Lab Facilities

Our Cognitive and Affective Neuroscience Laboratory includes several high-density EEG recording systems, including ones that are portable for data acquisition with special populations, and the latest software in modelling source generators. We also examine other psychophysiological responses, especially heart rate variability, as a reflection of parasympathetic control.

Current research interests outline for potential new graduate students

My research focus has been on methodological innovations in EEG and ERP research that allow us to examine more deeply psychological questions of information processing and the effect of individual differences on that processing. Most recently, we have been working with techniques involving ICA (for the derivation of latent components in the ERP), with source modelling (especially using sLORETA and sometimes BESA), ITC (inter-trial consistency measures for intra-subject variability in ERP responses), some new measures of cortical connectivity derived from EEG, and bootstrapping techniques for N=1 analyses.

With these techniques, we are able to ask questions of psychological importance such as those outlined below.

Performance monitoring

What happens in the human brain when people make correct or incorrect responses on simple challenge tasks, or when they make a gambling choice (pick one of two boxes to win or lose money)? The result is an interaction between the subcortical reward system of the brain and the prefrontal cortex monitoring region. I use EEG/ERPs to monitor these brain responses. Human brains react to a disappointing outcome with what are called error-related ERP components (especially the medial frontal negativities), which are easily recorded when someone realizes they have made an error.

These include the error-related negativity (ERN, or Ne) and positivity (Pe). Similarly, when one receives feedback concerning performance, a feedback-related negativity (FRN) is generated. We are working on understanding the cortical sources for these components and the cognitive and emotional contexts which influence their appearance, including the effects of heightened arousal during a task because of excitement.

Developmental differences

Some of the effects described above are affected by age. The prefrontal cortex of the adolescent brain is still rapidly maturing, and so does its production of the ERN. We are examining the relation between brain maturation and the production of various ERP components dependent on activity in the medial prefrontal cortex and what cognitive or personality characteristics account for the individual differences in this growth. These traits include executive functions, emotional self-regulation and reward-related personality characteristics, all aspects related to the mental health of children and youth.

Early stages of face, word and object perception

Information is processed extremely rapidly in the brain and reflected in ERPs. We are examining this rapid processing in the context of face perception, word reading and object perception. Some of our studies concern emotional face perception, especially as a function of the viewer’s personality, and others concern individual differences in the skill of the viewer in processing the stimuli.

Personality individual differences

We have also found that a person’s personality relates to his or her performance-related ERP responses (the ERN, Pe, FRN, and also the nogo-N2). Of particular interest to us are personality characteristics of risk-taking and sensation-seeking personality styles, responses to rewards and punishments, and the degree of empathy and obsessive-compulsiveness or perfectionism that the person shows. We think that the functioning of the medial prefrontal cortex is central to some of these individual differences.
