Integrating Field Work and Laboratory in Small Group Research

The influences responsible for the rapid increase in preoccupation with small groups spring both from within the academic development of various disciplines and from various agencies instituted for devising practical solutions for immediate application. A brief mention of influences contributing to small group research will serve as orientation to the main trail of this paper. (1) Theoretically and empirically, works of sociologists have historical priority in showing persistent concern with the topic of small groups.[1] Since the early 1920's a definite research development in sociology related to small groups has been carried on, as represented by the works of men like Thrasher, Anderson, Clifford Shaw, Zorbaugh, Hiller, Whyte. In the recurrent findings reported in this line of research, which was carried out over a period of a good many


( 760) years, one cannot help finding crucial leads for a realistic approach to experimentation in this area.

(2) Another source of research impulse is the practical concern of business and military agencies. A series of studies initiated by Elton Mayo and his associates at the Harvard Business School in the late 'twenties has proliferated in various institutions both academic and technological. Another impetus along this line came from the concern of military agencies for establishing effective techniques for the assessment of leaders.

(3) Another major influence in the development of small group studies comes from psychological research. No matter with what theoretical concepts they were introduced, psychological experiments almost always showed differential effects on the behavior of individuals when persons undertook an activity in relation to other individuals or even in their presence, as can be ascertained readily by a glance at Murphy, Murphy, and Newcomb's Experimental Social Psychology. F. H. Allport's experiments, which started around 1915, are illustrative of this point. In the 'thirties, it became increasingly evident that such social behavior as cooperation-competition, ascendance-submission, and the like, could not be properly studied when the individual is considered in isolation. Psychological "trait" theories or personality typologies fell far short in explaining social relations. Therefore, when Moreno's work appeared in this country in the middle 'thirties presenting his sociometric technique for the study of interpersonal choices and reciprocities among individuals (i.e. role relations), it was not long before it found wide application. A few years later Kurt Lewin and his associates demonstrated the weighty determination of individual behavior by the properties of group atmosphere. This line of experimentation was the basis of other subsequent studies coming from the proponents of the Group Dynamics school. Some other major influences coming from psychology will be mentioned in the course of the paper.

INTERDISCIPLINARY COOPERATION AND THE CONCEPT OF "LEVELS"

As becomes apparent even from this brief mention of the background, men from various disciplines contributed to make the study of small groups the going concern that it is today. As a consequence there is diversity of emphasis in formulating problems and hypotheses, and diversity in concepts used. This state of affairs has brought about considerable elbow-rubbing and interdisciplinary bickering among sociologists, psychologists, and anthropologists. In consequence of this process the interdisciplinary approach has become a necessity for achieving a rounded picture.

Faced with the task of dealing with both psychological and socio-cultural factors in human relations problems, psychologists have too often yielded to the temptation of improvising their own "sociologies" in terms of their preferred concepts. Sociologists, on the other hand, have sometimes engaged in psychological improvisations. While sociological or psychological improvisation at times proves necessary on the frontiers of a discipline, it is difficult to justify on topics for which a substantial body of research exists in sociology or in psychology, as the case may be.

In usual practice interdisciplinary cooperation is taken to imply rallying psychologists, sociologists, anthropologists, and other social scientists to toss their theories and concepts into the ring. As we have seen in the past, mere juxtaposition of utterances of psychologists, sociologists, and others, does not bring interdisciplinary cooperation. Nor is it possible to secure interdisciplinary integration by arranging segments from each discipline in a series.

The outlines of an interdisciplinary approach appear more clearly with the realization that "psychological" and "sociological" signify different levels of analysis. Men working in the human relations area are approaching related, similar, or even the same problems at different levels of analysis, necessitating units and concepts appropriate for dealing with events on that level. If we are working on the psychological level, our unit of analysis is the individual; hence our treatment must be in terms of his psychological functioning in concepts such as motives, judging, perceiving, learning, remembering, and imagining. If we are working on a sociological or cultural level, our concepts are in such terms as social organiza-


(761) -tion, institutions, value systems, language, kinship systems, art forms, and technology.

The concept of levels holds a fairly obvious but invaluable check on the validity of our findings. For if it is valid, a generalization reached at one level of analysis on the same topic is not contradicted and, in fact, gains support from valid generalizations reached at another level. For example, the psychologist's findings of differential behavior of an individual when participating in the activities of his group should be (and are) substantiated by findings on the sociological level, namely that collective action in a group has properties peculiar to the group. Checking and cross-checking findings obtained at one level against those obtained at another level on the same topic will make interdisciplinary cooperation the integrating meeting ground that it should be.

During the last century in the social sciences, and more recently in psychology, the dependence of sub-units upon the setting or superordinate system of which they are parts has been gaining weight, especially in the face of unrewarding attempts to account for the functioning system in an additive way. Understanding of part processes is possible only through analysis of their relations within the functioning system, as well as by analysis of unique properties of the part process itself. Unless knowledge of the superordinate or larger functioning system is gained first, before tackling the part processes, there is the likelihood of unwarranted generalizations concerning the parts, and misinterpreting the true functional significance of the processes observed.

In this connection an observation reported by Malinowski in 1922 in relation to the Kula exchange system is instructive. Even from the most intelligent native no coherent account of this exchange system could be obtained. "For the integral picture does not exist in his mind; he is in it, and cannot see the whole from the outside." [3]

This point can be illustrated in relation to small group studies. Since Lewin's experiments in the 1940's comparing lecture and group discussion methods in changing attitudes, various studies have shown that in the American setting skillfully conducted group discussion in which members participate is more effective than lecture presentation. On the basis of results obtained in the American setting, it would seem that the superiority of group discussion methods might be universal. That this is not the case is indicated by one of the studies in the UNESCO project in India.[4] In an attempt to modify caste attitudes among college students in India using various methods, the greatest changes arose as a result of a lecture method using emotional appeals. The experimenter wrote: "Contrary to our original expectation and hypothesis, these young boys do not seem to be in a position to exploit fully the discussion technique, in bettering their social relationships. Does it indicate that our boys have got to be used to the democratic ways of discussion and at present prefer to be told what are the right attitudes rather than to be allowed to talk them out?" Within a social organization whose values clearly encourage dependence on authority and effectively discourage settling issues on a give-and-take basis in small sub-units, particular dependencies may become so much a part of the individual's ego system that one could predict that group discussion techniques used in American studies would be less effective than methods more in harmony with the social organization in which it takes place.

Such comparative results illustrate the value of starting first with due consideration of the socio-cultural setting with its organization and values, before generalizations are made about small groups functioning as parts of that setting.[5] For small groups are not closed systems, especially in highly complex and differentiated societies such as the United States.

Facts obtained concerning the group setting are in terms of concepts and units at the social or cultural level of analysis. They will not give the step-by-step analysis of the particular interaction process; they will not be adequate for the task of dealing with interpersonal relations or behavior of particular individual members. At this point, psychological concepts are needed for a detailed analysis of reciprocal relations, for handling motives, perceptions, judgments, and the like.

SOME RECENT INVESTIGATIONS

The rest of the present paper is devoted to a summary statement of the attempts on our part toward pulling together some relevant findings in sociology and in psychology in the study of small groups. In these attempts the guiding considerations have been the following:

(1) To extract some minimum generalizations from the sociological findings on small groups on the one hand; on the other, to extract relevant principles from work coming from the psychological laboratory.

(2) To formulate problems and hypotheses relating to one another indications of the two sets of relevant findings, that is from sociological and psychological research.

(3) To test hypotheses thus derived with methods and techniques which are appropriate for the particular problem-experimental, observational, sociometric, questionnaire, or combinations thereof as the case may be.

Let us start with the term "small group" itself, which is coming to mean all things to all people. If the concept is considered at the outset, research on small groups will gain a great deal in the way of selection of focal problems for investigation, and hence effective concentration of efforts.

"Small group" may mean simply small numbers of individuals. If this is the criterion, any small number of individuals in a togetherness situation would be considered a small group. But a conception of small groups in terms of numbers alone runs counter to the properties of the actual small groups which have made their study such a going concern today.

One of the objectives of concentrating on small group research should be attainment of valid generalizations which can be applied, at least in their essentials, to any group and to the behavior of individual members. Accordingly, one of our first tasks has been that of extracting some minimum essential features of actual small groups from sociological work. In this task there is a methodological advantage in concentrating on informally organized groups, rather than formally organized groups in which the leader or head, and other positions with their respective responsibilities, are appointed by a higher authority, such as a commanding officer or board. In informally organized groups, group products and the particular individuals who occupy the various positions are determined to a much greater extent by the actual interaction of individuals. If we are careful at the beginning to refer to the general setting in which small groups form and function, their products and structure can be traced through longitudinal observation of the interaction process.

On the basis of an extensive survey of sociological findings, the following minimum features in the rise and functioning of small groups were abstracted:

(1) There are one or more motives shared by individuals and conducive to their interacting with one another.

(2) Differential effects on individuals are produced by the interaction process, that is, each individual's experience and behavior is affected in varying ways and degrees by the interaction process in the group .[6]

(3) If interaction continues, a group structure is stabilized consisting of hierarchical status and role relationships, and is clearly delineated as an in-group from other group structures.

(4) A set of norms regulating relations and activities within the group and with non-members and out-groups is standardized.[7]


( 763)

We have not made interaction a separate item in these minimum features, as some writers have, because interaction is the sine qua non of any kind of social relationship, whether interpersonal or group. Since human interaction takes place largely on a symbolic level, communication is here considered part and parcel of the interaction process.

When group structure is analyzed in terms of hierarchical status positions, the topic of power necessarily becomes an integral dimension of the hierarchy. Power relations are brought in as an afterthought only if this essential feature of group hierarchy is not brought into the conception of group. Of course, power does in many cases stem from outside of the group, and in these cases the nature of established functional relations between groups in the larger structure has to be included in the picture.

Our fourth feature relates to the standardization of a set of norms. The term "social norm" is a sociological designation referring generically to all products of group interaction which regulate members' behavior in terms of the expected or even the ideal behavior. Therefore, norm does not denote average behavior.[8] The existence of norms, noted by sociologists, has been experimentally tested by psychologists in terms of convergence of judgments of different individuals [9] and in terms of reactions to deviation.[10] A norm denotes not only expected behavior but a range of tolerable behavior, the limits of which define deviate acts. The extent of the range of tolerable behavior varies inversely with the significance or consequence of the norm for the identity, integrity, and major goals of the group.

With these minimum essential features of small informally organized groups in mind, a group is defined as a social unit which consists of a number of individuals who, at a given time, stand in more or less definite interdependent status and role relationships with one another, and which explicitly or implicitly possesses a set of norms or values regulating the behavior of the individual members, at least in matters of consequence to the group.

Common group attitudes or sentiments are not included in this definition because social attitudes are formed by individuals in relation to group norms as they become functioning parts in the group structure. At the psychological level, then, the individual becomes a group member to the extent that he internalizes the major norms of the group, carries on the responsibilities, and meets expectations for the position he occupies. As pointed out by various authors, his very identity and self conception, and his sense of security, become closely tied to his status and role in the group through the formation of attitudes relating to his membership and position. These attitudes may be termed "ego-attitudes" which function as constituent parts of his ego system.

On the basis of findings at a sociological level, hypotheses concerning the formation of small in-groups and relations between them were derived and tested in our 1949 camp experiment." One of the major concerns of that study was the feasibility of experimental production of in-groups among individuals with no previous role and status relations through controlling the conditions of their interaction.

The hypotheses tested were:

(1) When individuals having no established relationships are brought together to interact in group activities with common goals, they produce a group structure with hierarchical statuses and roles within it.

(2) If two in-groups thus formed are brought into functional relationship under conditions of competition and group frustration, attitudes and appropriate hostile actions in relation to the out-group and its members will arise and will be standardized and shared in varying degrees by group members.

As sociologists will readily recognize, testing of these hypotheses is not so much concerned with the discovery of new facts as


( 764) getting a clearer picture of the formative process under experimentally controlled conditions. It aims rather at singling out the factors involved in the rise of group structure, group code or norms, and in-group-out-group delineation which will make their intensive study with appropriate laboratory methods on the psychological level possible.

To test these hypotheses, 24 boys of about 12 years of age from similar lower middle class Protestant backgrounds were brought to an isolated camp site wholly available for the experiment. The early phase (stage I) of the study consisted of a variety of activities permitting contact between all the boys, and observation of budding friendship groupings. After being divided into two groups of 12 boys each (stage II) in order to split the budding friendship groupings and at the same time constitute two similar units, the two groups lived, worked and played separately. All activities introduced embodied a common goal (with appeal value to all) the attainment of which necessitated cooperative participation within the group.

At the end of this stage, there developed unmistakable group structures, each with a leader and hierarchical statuses within it, and also names and appropriate group norms, including sanctions for deviate behavior. Friendship preferences were shifted and reversed away from previously budding relationships toward in-group preferences. Thus our first hypothesis concerning in-group formation was substantiated.

In the final phase (stage III), the two experimentally formed in-groups were brought together in situations which were competitive and led to some frustration as a consequence of the behavior of the groups in relation to each other. The result of intergroup contact in these conditions was enhancement of in-group solidarity, democratic interaction, and in-group friendship on the one hand, and out-group hostility, name calling and even fights on the other, indicating that in-group democracy need not lead to harmonious relations with outsiders when the nature of intergroup relations is fraught with conditions conducive to tension. The resistance which developed to post-experimental efforts at breaking down the in-groups and encouraging friendly interaction is indicative of the unmistakable effect of group products on individual members. Thus this study substantiated the second hypothesis concerning determination of norms toward out-groups by the nature of relations between groups, and demonstrated some effects of intergroup relations upon in-group functioning.

One of the main methodological considerations of this experiment was that subjects were kept unaware of the fact that they were participating in an experiment on group relations. The view that subjects cease to be mindful that their words and deeds are being recorded is not in harmony with what we have learned about the structuring of experience. The presence of a personage ever observing, ever recording our words and deeds in a situation in which our status and role concerns are at stake cannot help coming in as an important factor in the total frame of reference. Therefore, in our work, the aim is to establish definite trends as they develop in natural, life-like situations and to introduce precision at choice points when this can be done without sacrificing the life-like character which gives greatest hope for validity of these trends.

The study just summarized illustrates the testing of hypotheses derived from sociological findings in experimentally designed situations. Our next point relates to psychological findings, generalizations, and laboratory techniques relevant to the study of experience and behavior of individual group members. Here our task is to achieve a more refined analysis on a psychological level of individual behavior in the group setting through precise perceptual and judgmental indices. If such data obtained through precise judgmental and perceptual indices and other appropriate techniques are in line with findings concerning group relations on the sociological level, then we shall be moving toward integration of psychological and sociological approaches in the study of group relations.

Here we can state only the bare essentials of the psychological principles, coming from a major trend in experimental psychology, which are utilized in designing the experiments to be reported.[12]


( 765)

Judgments and perceptions are not merely intellectual and discrete psychological events. All judgments and perceptions take place within their appropriate frame of reference. They are jointly determined by functionally related internal and external factors operating at a given time. These interrelated factors-external and internal--constitute the frame of reference of the ensuing reaction. Observed behavior can be adequately understood and evaluated only when studied within its appropriate frame of reference or system of relations. The external factors are stimulus situations outside of the individual (objects, persons, groups, events, etc.). The internal factors are motives, attitudes, emotions, general state of the organism, effects of past experience, and the like. The limit between the two is the skin of the individual-the skin being on the side of the organism.

It is possible, therefore, to set up situations in which the whole appraisal, evaluation of a social situation, will be reflected in the judgments and perceptions of the individual. In short, under appropriate and relevant conditions, the way the individual sizes up a situation in terms of the whole person he is at the time can be tapped through seemingly simple perceptual and judgmental reactions.

An additional feature of this underlying principle should be clearly stated because of certain conceptions in psychology which make perception almost an altogether arbitrary, subjective affair. If external stimulus situations are well structured in definite objects, forms, persons, and groupings, perception will correspond closely to the stimulus structure on the whole. This is not to say that functionally related internal factors do not play a part in the perception of structured situations. The fact that some well-structured situations rather than others are singled out as "figure" by the individual indicates that they do. Such facts are referred to under the concept of perceptual selectivity.

If, on the other hand, the external field is vague, unstructured, in short, allows for alternatives-to that extent the relative weight of internal factors (motives, attitudes) and social factors (suggestion, etc.) will increase. It is for this reason that the exhortations of the demagogue are relatively more effective in situations and circumstances of uncertainty. Since perceptions, judgments, and like processes, are jointly determined by external and internal factors, it is possible to vary their relative weights in differing combinations, giving rise to corresponding judgmental and perceptual variations, and this has been done in various experiments. In a study carried out as part of our project at the University of Oklahoma, James Thrasher covaried systematically the stimulus situation in gradations of structure, and the nature of interpersonal relations of subjects (strangers and friends), to determine the reciprocal effects of these variations on judgmental reactions. It was found that as the stimulus situation becomes less structured, the correspondence between stimulus values and judgment values decreases, and the influence of social factors (established friendship ties in this case) increases.[13]

Following the implications of the above, it is plausible to say that behavior revealing discriminations, perceptions, evaluations of individuals participating in the interaction process as group members will be determined: not only by whatever motivational components and unique personality characteristics each member brings with him, and not only by the properties of stimulus conditions (social or otherwise) specified in an unrelated way, but as influenced, modified, and even transformed by these and by the special properties of the interaction process, in which a developing or established state of reciprocities plays no small part. Interaction processes are not voids.

The starting point in our program of research was the experimental production of group norms and their effects on perception and judgment.[14] This stems from our concern for experimental verification of one


( 766) essential feature of any group-a set of norms (feature 4 of small groups above). Groups are not transitory affairs. Regulation of behavior in them is not determined by the immediate social atmosphere alone.

Especially suggestive in the formulation of the problem was F. Thrasher's observation on small groups that behavior of individual members is regulated in a binding way (both through inner attachment and, in cases of deviation, through correctives applied) by a code or set of norms. Equally provocative in this formulation was Emile Durkheim's Elementary Forms of Religion, in which a strong point was made of the rise of représentations collectives in interaction situations and their effect in regulating the experience and outlook of the individual.

After thus delineating the problem, the next step was to devise an experimental situation which lacked in objective anchorages or standards (was vague or unstructured) in order to maximize the effects of the social interaction process. When individuals face such an unstructured stimulus situation they show marked variations in reaction. However, these marked individual variations will not occur if the stimulus is a definite, structured object like a circle or a human hand. There will be agreement among individuals on the whole when they face a circle or a normal hand even if they are five-thousand miles apart and members of different cultures. The fact of objective determination of perception and judgment and the ineffectiveness of social influences (suggestion, etc.) in relation to structured stimuli was clearly noted in the original report of this experiment in several contexts. In a later publication, to stress cases of objective determination of psychological processes, a chapter was devoted to the effects of technology and its decisive weight in determining social norms and practices, with numerous illustrations from various parts of the world. Among them was our study conducted in the early 'forties of five Turkish villages with varying degrees of exposure to modern technology, specifically dealing with the compelling effects of such differential exposure on judgmental, perceptual, and other psychological processes.[15]

The experimental situation chosen for the unit studying norm formation was the autokinetic situation (the apparent movement of a point of light in a light-proof room lacking visible anchorages). The dimension chosen was the extent of movement. As this study is printed in detail in various places, only the bare essentials are given here.

First it was established that the judgment of the extent of movement for given brief exposures varies markedly from individual to individual. Then individuals were brought to the situation to make their judgments together. If, during the course of their participation, their judgments converge within a certain range and toward some modal point, we can say they are converging to a common norm in their judgments of that particular situation. It is possible however that this convergence may well be due to immediate felt social pressure to adjust to the judgments spoken aloud by the other participants in the situation. Therefore, going a step further, if it is shown that this common range and modal point are maintained by the individual in a subsequent session on a different day when he is alone, then we can say that the common range and modal point have become his own.

The results substantiated these hunches. When individuals face the same unstable, unstructured situation for the first time together with other participants, a range of judgment and a norm within it are established which are peculiar to that group. After the group range and norm are established, an individual participant facing the same situation alone makes his judgments preponderantly in terms of the range and norm that he brings from the group situation. But convergence of judgments is not as marked as this when individuals first go through individual sessions and then participate in group sessions.

When the individual gives his judgments repeatedly in the alone situation, the judgments are distributed within a range and


( 767) around a modal point peculiar to the individual. This finding has important theoretical implications. The underlying psychological principle, in individual and group situations, is the same, namely that there is a tendency to reach a standard in either case. Here we part company with Durkheim and other sociologists who maintained a dichotomy between individual and social psychology, restricting the appearance of emergent properties to group situations alone. In both cases, there are emergent properties. In the individual sessions they arise within the more limited frame of reference consisting of the unstructured stimulus situation and special psychological characteristics and states of the individual; whereas in togetherness situations the norm is the product of all of these in the particular interaction situation. The norm that emerges in group situations is not an average of individual norms. It is an emergent product which cannot be simply extrapolated from individual situations; the properties of the unique interaction process have to be brought into the picture. Therefore, the fact remains that group norms are the products of interaction process.

In a subsequent unit, it was found that a characteristic mode of reaction in a given unstructured situation can be produced through the introduction of a prescribed range and norm.[16] When one subject is instructed to distribute his judgments, within a prescribed range around a modal point, which vary for each naive subject, the preponderant number of judgments by the naive subjects come to fall within the prescribed range and around the modal point introduced for them, and this tendency continues in subsequent alone sessions. This tendency is accentuated if the cooperating subject has prestige in the eyes of the naive subject. These findings have been substantiated in a number of studies. For example, it has been shown that the tendency to maintain the prescribed range persists after several weeks.[17] The actual presence of another person who makes judgments within a range prescribed by the experimenter is not essential. Norman Walter demonstrated that a prescribed norm can be produced through introduction of norms attributed to institutions with high prestige.[18] A prescribed distribution of judgments given by tape recording is similarly effective.[19] A prescribed range can be established, without social influence, through prior experience in a more structured situation with light actually moving distances prescribed by the experimenter.[20]

The advantages of a technique such as the autokinetic device for studying norm formation and other aspects of group relations are: (1) Compared with gross behavioral observations, it yields short-cut precise judgmental indices along definite dimensions reflecting individuals' own appraisals or sizing-up of the situation. (2) Judgmental or perceptual reaction obtained is indirect, that is, it is obtained in relation to performance and situations which do not appear to the subject as directly related to his group relations, his positive or negative attitudes. The feasibility of the use of judgmental variations demonstrated in this study constituted the basis of its use in subsequent studies dealing with various aspects of group relations.

At this point, longitudinal studies will bring more concreteness to the process of norm formation. As Piaget demonstrated in his studies of rules in children's groups, the formation of new rules or norms cannot take place until the child can perceive reciprocities among individuals.[21] Until then he abides by rules because people important in his eyes or in authority say that he shall. But when the child is able


( 768) to participate in activities grasping the reciprocities involved and required of the situation, then new rules arise in the course of interaction, and these rules become his autonomous rules to which he complies with inner acceptance. Although this is in contrast to some still prevalent psychological theories (e.g. Freud), these longitudinal findings are in line with observations on norm formation and internalization in adolescent cliques and other informally organized groups. These are among the considerations which led us to an intensive study of ego-involvements, and to experimental units tapping ego-involvements in interpersonal relations and among members occupying differing positions in the status hierarchy of a group.

These experimental units represent extensions of the approach summarized to the assessment of (a) positive or negative interpersonal relations, (b) status relations prevailing among the members of in-groups, (c) positive or negative attitudes toward given out-groups and their members.

The first units along these lines dealt with interpersonal relations. It was postulated that since estimates of future performance are one special case of judgmental activity in which motivational factors are operative, the nature of relations between individuals (positive or negative) will be a factor in determining variations in the direction of these estimates. This inference was borne out first in a study showing that estimates of future performance are significantly affected by strong positive personal ties between subjects. [22] In a later unit, the assessment of personal relations through judgments of future performance was carried to include negative interpersonal relations as well as positive.[23] In line with the hypothesis, it was found that individuals tended to overestimate the performance of subjects with whom they had close positive ties, and correspondingly to underestimate the future performance of those with whom they had an antagonistic relationship.

The study of status relations in small groups followed .[24] This study is related to feature 3 in our discussion of the essential properties of groups (above), namely, the rise and effects of hierarchical status structure. Observations by the sociologist, William F. Whyte, gave us valuable leads in formulating the specific problem of this study. During one period, a Street Corner clique that Whyte observed was engaged seriously in bowling. Performance in bowling became a sign of distinction in the group. At the initial stage, some low status members proved themselves on a par with high status members, including the leader. This ran counter to expectations built up in the group hierarchy. Hence, in time, level of performance was stabilized for each member in line with his relative status in the group. In the experiment, O. J. Harvey first ascertained the status positions of individual members in adolescent cliques. This was done through status ratings by adults in close contact with the subjects, through sociometric ratings from clique members, and through observations of some of the cliques by the experimenter during their natural interaction. Cliques chosen for the final experiment were those in which there was high correspondence between the status ratings obtained.

The overall finding is that the higher the status of a member, the greater his tendency and that of other group members to overestimate his future performance. The lower the status of a group member, the less is the tendency of other group members and of himself to overestimate performance, even to the point of underestimation. If these results are valid, it should prove possible to predict leaders and followers in informal groups through judgmental variations exhibited in the way of over- and underestimations of performance.

In the summer of 1953 our first attempt was made at a large-scale experiment starting with the experimental formation of in-groups themselves and embodying as an


( 769) integral part of the design the assessment of psychological effects of various group products.[25] This assessment involved laboratory-type tasks to be used in conjunction with observational and sociometric data. The overall plan of this experiment was essentially like that of the 1949 study and called for carrying through a stage of ingroup formation, to a stage of experimentally produced intergroup tension, and finally to integration of in-groups. The scope of this experiment embodying laboratory-type procedures at crucial points in each stage proved to be too great for a single attempt. During the period of intergroup relations (stage III), the study was terminated as an experiment due to various difficulties and unfavorable conditions, including errors of judgment in the directing of the experiment.

The work completed covered the first two stages and will be summarized here very briefly. The plan and general hypotheses for these stages are similar on the whole to those of the 1949 study summarized earlier.

Prior to the experiment, subjects were interviewed and given selected tests administered by a clinical psychologist. The results of these assessments will be related to ratings made by the experimental staff along several behavioral dimensions during the experiment proper, when in-group interaction had continued for some time.

At the end of the second stage, two in-groups had formed as a consequence of the experimental conditions, although the rate of group formation and the degree of structure in the two groups were somewhat different.

Our hypothesis concerning experimental formation of in-groups substantiated in the 1949 study was supported. As a by-product of in-group delineation we again found shifts and reversals of friendship choices away from the spontaneous choices made prior to the division of groups and toward other in-group members.

At the end of this phase of in-group formation, just before the first scheduled event in a tournament between the two groups, psychological assessment of group members within each status structure was made through judgments obtained in a laboratory-type situation. In line with methodological concerns mentioned earlier in the paper, the experimental situation was introduced to each group by a member of the staff with the proposal that they might like to get a little practice for the softball game scheduled later that day. When this proposal was accepted, the experimenter took each group separately and at different times to a large recreation hall where he suggested turning the practice into a game, in which everyone took turns and made estimates of each others' performance. This was accepted as a good idea. Thus each boy took a turn at throwing a ball at a target 25 times and judgments of his performance were made by all members after each trial.

It should be noted that in previous studies, judgments of future performance were used as an index. The important methodological departure here was using as the unit of measurement the difference between actual performance and judgment of that performance after it was executed. In order to do so the stimulus situation had to be made as unstructured as possible so that the developing status relations would be the weighty factor in determining the direction of judgmental variations.

In line with our hypothesis in this experimental unit, the results indicate that variations in judgment of performance on the task were significantly related to status ranks in both groups.[26] The performance of members of high status was overestimated by other group members; the performance of members of low status tended to be underestimated. The extent of over- or underestimation was positively related to the status rankings. Variations in judgment of performance on the task were not significantly correlated with skill, or actual scores, of the members. This should not be interpreted to mean that skill can be discarded as a factor or that it would not be highly related to judgmental variation in a more structured task. Of the two


( 770) groups, skill seemed to be of relatively greater importance in the group which achieved less stability and solidarity. This is one of several indications that the relationship between judgmental variation and status rankings is closer in the group of greater solidarity and greater stability of structure. This finding of a relationship between degree of stability of the structure on the one hand and psychological response of members as revealed in their judgments, on the other, points to the necessity of systematic concern with the degree of group structure and solidarity as a variable in small group studies. In particular it should be brought systematically into the study of leadership and problems of conformity.[27]

We hope to gain greater understanding of the relationship between stability of group structure and psychological reactions as revealed by judgmental indices through a new study designed for this purpose. In this attempt the task will be held constant and the degree of established status relationships among subjects will be varied. At one extreme, subjects will be complete strangers; at the other extreme, subjects will be members of highly structured groups. The hypothesis to be tested is that judgments will be more a function of actual performance in the task in the case of strangers, and progressively more a function of existing status relations and less of skill with the increasing degrees of stability of group structure.

Following the experimental assessment of psychological effects of group structure in existing and in experimentally formed in-groups, the next step in our program of research was to extend the use of judgmental variation techniques to the level of intergroup relations among already existing groups. Such an experimental unit has recently been completed by O. J. Harvey.[28]

Harvey investigated relations between existing informally organized groups and their effects on in-group functioning and on evaluations of the in-group and out-group. Organized cliques were chosen on the same basis as those in the study of status relations in existing informally organized groups already summarized. In the first experimental session, in-group members judge each others' performance on a task. In the second session, two cliques with either positive or negative relationships with each other, as the case may be, are brought to the situation together. Here a similar procedure is followed, with in-group members judging performance both of other in-group members and performance of members of the functionally related out-group. In addition, subjects rate in-group and out-group members on 10 adjectival descriptions presented on a graphic scale. These ratings were included to yield data relevant to our hypothesis concerning the nature of group stereotypes in the 1949 study and those of Avigdor's study on the rise of stereotypes among members of cooperating and rival groups.[29]

Results obtained in this experiment bear out the hypotheses. Greater solidarity is evidenced in the in-group when out-groups are present, as revealed by an increasing relationship between judgmental variation and status ranks and by greater overestimation of performance by in-group members. In-group performance tends to be judged above that of out-group members when the groups are antagonistic, which is not the case when the groups present are positively related to each other. Finally, results clearly show a much higher frequency of favorable attributes for in-group members (e.g." extremely considerate," "extremely cooperative") and a much higher frequency of unfavorable attributes given members of an antagonistic out-group (e.g. "extremely inconsiderate," "extremely uncooperative"). The difference between qualities attributed to in-group members and members of friendly out-groups is much


( 771) smaller and not so clear-cut, as would be expected.

Thus, having demonstrated the feasibility of experimental study of norm formation, of status relations within groups, and of positive and negative attitudes between groups through laboratory-type techniques on the one hand and, on the other, experimental production of in-groups themselves in two previous studies, our next step is to carry through the large-scale experiment, along the lines of our 1953 attempt, which will pull together all of these various aspects into one design. Judgmental indices reflecting developing in-group and intergroup relations are to be obtained through laboratory-type techniques at choice points, in a way that does not clutter the flow of interaction process. These judgmental indices can be checked against data obtained through more familiar observational, sociometric, and like methods. If indications of the findings through judgmental processes are in line with the trends obtained by gross observational and other methods, then we can say the generalizations reached are valid. If this can be established, the laboratory-type experiment can be offered as a more precise and refined method of assessing the effects of interaction process in group relations.

This approach, which takes the behavior of individuals as an outcome of interaction process into which factors coming from the individual himself with his unique characteristics and capacities, and coming from properties of the situation, enter, affords a naturalistic behavioral setting against which the claims of various personality tests can be evaluated.

The successive phases of this comprehensive experimental plan are:

(a) Experimental production of in-groups themselves with a hierarchical structure and set of norms (intra-group relations). In line with our 1949 and 1953 studies, this is done, not through discussion methods, but through the introduction of goals which arise in the situations themselves, which have common appeal value, and which necessitate facing a common problem, leading to discussion, planning and execution in a mutually cooperative way.

(b) Bringing into functional relations the two experimentally formed groups in situations in which the groups find themselves in competition for given goals and in conditions which imply some frustration in relation to one another (intergroup tension).

(c) Introduction of goals which cannot be easily ignored by members of the two antagonistic groups, but the attainment of which is beyond the resources and efforts of one group alone. In short, superordinate goals are introduced with the aim of studying the reduction of intergroup tension to derive realistic leads for the integration of hostile groups.[30]
