Most things we study in psychology—behaviour, emotion, cognition and so on—show widespread individual differences. Some of us experience anxiety more readily or frequently than others, and some of us are more gregarious and talkative compared to our quieter counterparts. The description of such individual differences, and identification of their various causes and consequences, is the focus of personality psychology.


Researchers in the Personality Processes Lab study a broad range of topics in personality psychology, ranging from the neurobiological correlates and causes of personality traits through to the implications of those traits for our wellbeing and social behavior.
