-ERPs, Vagal Tone

Dr. Dywan is a clinical neuropsychologist who studies age-related changes in cognitive function as they occur in healthy older adults. She focuses particularly on the relationship between a decline in attentional control and the ability to monitor the source of remembered events. By examining electrical event-related brain activation while participants engage in various cognitive tasks, she monitors neural activity occurring prior to a behavioural response. In this context, Dr. Dywan has also been examining the relation between heart-rate variability (vagal tone), an index of general physiological response, and control attention and response tendencies. She is also investigating how the general physiological reactivity associated with the perception of emotional information interacts with other cognitive functions. The inability to accurately perceive and physiologically respond to emotional expression may lead to an inappropriate response. In this regard, she has studied individuals with traumatic brain injury and violent offenders who vary in their degree of psychopathy.
