Building such models forces one to be explicit about the mechanisms underlying a particular phenomenon and how those mechanisms interact with each other.\u00a0 Running such models provides a plausibility test\/existence proof for the theories you develop and implement in such models.\u00a0 Our lab focuses on building neurobiologically plausible neural network models in a variety of different domains:<\/p>\n<ul style=\"font-weight: 400;\">\n<li>Motivation\n<ul>\n<li>The Structure and Dynamics of Human Personality<\/li>\n<li>Motivated Decision-making and Behavior<\/li>\n<li>Pathologies of Motivation: Depression, Anxiety<\/li>\n<\/ul>\n<\/li>\n<li>Social Evaluation and Threat Perception<\/li>\n<li>Coherence-based Reasoning in Legal and Everyday Decision-making<\/li>\n<li>Coherence in Belief Systems, Belief Change attitude accessibility and the consistency of belief systems<\/li>\n<li>Impression Formation and Person Perception<\/li>\n<\/ul>\n<p style=\"font-weight: 400;\">We are currently developing connectionist (neural network) models to better understand motivation, personality, depression &amp; anxiety, person perception, attitudes &amp; beliefs, social reasoning, and social behavior.
