Comprehensively examining the relationship between cognition and emotion, this authoritative handbook brings together leading investigators from multiple psychological subdisciplines. Biological underpinnings of the cognition-emotion interface are reviewed, including the role of neurotransmitters and hormones. Contributors explore how key cognitive processes -- such as attention, learning, and memory -- shape emotional phenomena, and vice versa. Individual differences in areas where cognition and emotion interact -- such as agreeableness and emotional intelligence -- are addressed. The volume also analyzes the roles of cognition and emotion in anxiety, depression, borderline personality disorder, and other psychological disorders.
