Veena Dwivedi delivered an invited lecture at the Donders Institute for Brain, Cognition and Behaviour (centre includes Max Planck Institute of Psycholinguistics and Radboud University) in Nijmegen, The Netherlands. Her talk was entitled, Investigations in neurocognitive mechanisms underlying semantic ambiguity.
Language comprehension requires integration of information derived from world-experience and grammar. Nevertheless, how these different sources of information interact is debated. The present work suggests that language processing requires both heuristic and algorithmic processing streams, where the heuristic processing strategy precedes the algorithmic phase. This claim contrasts with recent accounts in the ERP language literature, which propose that these two streams operate in parallel. However, I suggest that evidence supporting the parallel processing model could be artefacts of Event Related Potential (ERP) language methodology.
The proposal is based on three self-paced reading experiments in which the processing of two-sentence discourses was investigated, where context sentences exhibited quantifier scope ambiguity. Experiment 1 demonstrates that such sentences are processed in a shallow manner. Experiment 2 uses the same stimuli as Experiment 1 but adds questions to ensure deeper processing. Results indicate that reading times are consistent with the lexical-pragmatic interpretation of number associated with context sentences, whereas responses to questions are consistent with the algorithmic computation of scope. Experiment 3 shows the same pattern of results using stimuli exhibiting a different lexical-pragmatic bias. These results suggest that for certain constructions, language processing is superficial and deeper processing sensitive to structure only occurs if required. Finally, recent ERP results in our lab confirm these hypotheses.

Veena Dwivedi presented a poster entitled “Evidence of competition for resources in number interpretation" (co-authors were former lab member Rae Gibson now at Western pursuing MSc. in Neuroscience, and James Desjardins) at the 11th International Symposium of Psycholinguistics in Tenerife, Spain.
As part of the Department of Applied Linguistics Speaker Series, Dr. John Connolly, who is Senator William McMaster Chair in Cognitive Neuroscience of Language at McMaster University, presented his talk, “Applied Neurolinguistics: the nexus of speech processing, linguistics, and applied linguistics.”
Congratulations to two members of the Brain and Language Lab, Lynsey Endicott and Rae Gibson, who graduated in June.
Kaitlin Curtiss gave her first national conference presentatation at Wilfried Laurier University, in Waterloo, Ontario at Congress 2012 Humanties and Social Sciences.
She presented a poster at the Canadian Linguistics Association entitled “Interpreting quantifier scope ambiguity” (co-authors were lab members Lynsey Endicott, Rae Gibson and Veena Dwivedi).
Veena Dwivedi gave a talk entitled “Concepts before composition: semantic processing”, earlier that day at the conference.
Veena Dwivedi was in New York City presenting at the 25th annual meeting of the CUNY Sentence Processing Conference.
The title of her poster was “Quantifier scope ambiguity and the timing of algorithmic processing”. Later that month, at the the annual meeting of the Cognitive Neuroscience Society in Chicago, she presented a poster “Doubly quantified sentences: Shallow vs. deep processing” (co-authors were lab member Rae Gibson and lab alumna, Leanne Angus).
Veena Dwivedi gave a talk entitled “Semantic ambiguity in language processing” (co-authors are Leanne Angus, now at SUNY-Buffalo, Raechelle Gibson and Chi Ho Alex Cheung), on May 29, 2011 at the Canadian Linguistic Association which held its 2011 conference as part of the Congress of the Social Sciences and Humanities, at the University of New Brunswick, Fredericton.
Veena Dwivedi gave an invited lecture entitled “Shallow processing of scope” for the Cognitive Science of Language Lecture Series at McMaster University on Jan. 26, 2011.
