Affective Style, Mood, and Anxiety Disorders
An Affective Neuroscience Approach
This chapter opens with a definition of affective style and its role in an individual's temperament, personality, and vulnerability to psychopathology. The constituents of affective style which involve concepts of emotion regulation, individual response thresholds, peak amplitude, response peaking time, recovery time, and affective chronometry are then discussed. An overview of two basic motivational systems—approach and withdrawal—is also provided, followed by a presentation of findings from studies examining individual differences in prefrontal activation statistics in relation to emotion, affective style, and biological constructs. These differences identified in the studies are then applied to psychopathology to reveal which individual affective styles are more prone to vulnerabilities and which exhibit resilience. This in turn has implications for an individual's response to stressful life events. The final section discusses applications of the above research in the assessment, treatment, and plasticity of affective and anxiety disorders.
