Abstract: College Students is a special group. Many students are deeply afflicted by unhealthy emotions. Therefore, a lot of psychological problems appear. One important reason for the appearance of these unhealthy emotions is the conflict and dislocation of cognitions. Cognitive theories such as the RET theory have original effects on the relieving of students′ emotional afflictions. The effects are as follows: (1) to help the students find and change their unrational belief;(2) to help the students to set a rule of "changing the train of thought" in their lives;(3) to help the students to use Rational-Emotive Imagery;(4) to help the students to learn self-evaluation objectively.

Key words: cognitive theories, emotion, distress, relieving
