Loneliness

Research and theory on the origins of loneliness and social isolation. Brain mechanisms, personality traits, and environmental factors that influence loneliness. Cultural differences in loneliness, and how loneliness differentially influences different populations. Interventions and ways to enhance social connections. 

Stereotyping and Prejudice
Ageism; Cognitive processes associated with use of stereotypes in impression formation; role of affect in guiding attitudes about stereotyped others; affective outcomes of using cognitive heuristics in intergroup interaction.

Cognitive Neuroscience
Neural substrates associated with various social behaviors, with special emphasis on working memory, and cognitive inhibition. Neural substrates of inhibition of affective and non-affective concepts. Influence of age on the ability to inhibit influence of unwanted & irrelevant information in working memory tasks (e.g. attitude formation). Use of fMRI to examine social cognitive neuroscience questions.

Attitudes
Impact of affective and cognitive attitude components on attitude change; formation and representation of attitude components in memory; measurement of peripheral cue representation; direct and indirect means of attitude formation and change.

Prosocial Behavior
Egoistic vs. altruistic motives for prosocial behavior; evidence for a unitary or multifaceted ultimate goal in prosocial behavior; cognitive and affective processes in empathy-motivated helping behavior; effects of implicit attitudes on prosocial behavior.

Self-Regulation
Organization of goal-directed behavior; action maintenance; cognitive arousal in discrepancies between real-ideal behavioral states; effects of affective states on goal-pursuit and disengagement; cognitive self-efficacy appraisal processes at decisional junctures in goal-directed behavior.
