Final answer:
Cognitive therapy aims to modify irrational thoughts and beliefs, helping individuals recognize that their negative perceptions, such as self-blame in failed marriages, may not be entirely accurate.
Step-by-step explanation:
Cognitive therapy seeks to change irrational thoughts and unrealistic beliefs; a cognitive therapist would try to get John, a three-time divorced man who blames himself entirely for his failed marriages, to understand how his marital failures were not entirely his fault.
The goal of cognitive therapy is to help individuals like John identify patterns of negative thinking and to challenge and modify these constructs to improve emotional well-being and behavior. By adopting new, more rational beliefs, one can reduce feelings of distress and develop healthier patterns of thinking and behavior.
