The premise that an individual's behavior and affect are largely determined by his or her attitudes and assumptions about the world underlies:

Cognitive Behavioural therapy is a form of psychotherapy that emphasizes the important role of thinking in how we feel and what we do.

Key Points

• It takes into account the individual's behavior as well as cognition which includes thinking and emotions.
• It focuses on identifying and changing maladaptive patterns of information processing and related behaviors. 
• It shares three fundamental propositions:
  • Cognitive activity affects behavior
  • Cognitive activity may be altered and monitored
  • Desired behavior change may be effective through cognitive change.
• The cognitive behavioral approach is based on the assumption that anxiety, depression, and negative emotions develop from maladaptive thought processes.

Hence we conclude that the premise that an individual's behavior and effect are largely determined by his or her attitudes and assumptions about the world underlies Cognitive-behavior therapy.
