Final answer:
It is true that in REBT, 'musts,' 'oughts,' and 'shoulds' are replaced with preferences, helping clients think more flexibly and reduce stress.
Step-by-step explanation:
The statement that clients learn in Rational Emotive Behavior Therapy (REBT) that "musts," "oughts," and absolute "shoulds" can be replaced by preferences is true. In REBT, developed by Albert Ellis, the idea is to challenge and change irrational beliefs, such as rigid demands on oneself or others, which are often phrased as 'musts' and 'shoulds'. Instead, clients are encouraged to adopt more flexible and realistic preferences, which alleviates the stress and pressure that comes with absolute thinking.
This practice aligns with the principles of metacognition, in which individuals reflect on their thoughts and feelings more objectively.
