Definition: People prefer increasing rewards and praise, and dislike decreasing evaluations and treatment; this is a social psychological phenomenon. Core Principles: 1. **First Criticize, Then Praise:** Highest Likelihood: Initial criticism followed by gradual praise is most likely to generate goodwill. 2. **First Praise, Then Criticize:** Lowest Likelihood: Initial praise followed by constant negativity is most likely to cause resentment. 3. **Constant Praise/Constant Criticism:** Both lead to a relatively neutral experience. Simple Examples: - A colleague's initial indifferent attitude towards you, followed by increasing recognition, will make you happy. - A friend's initial constant praise followed by gradual coldness and criticism will leave you feeling extremely disappointed. Life Applications: - Interpersonal Relationships: Avoid excessive flattery at the beginning; gradually affirm others for a more stable relationship. - Education/Management: Timely encouragement after criticism is far more effective than constant criticism or praising first and then suppressing. - Self-Presentation: Don't showcase all your strengths at the first meeting; gradually reveal your advantages to gain favor.
