In interpersonal interaction, body language can indeed convey strong messages, but ethics and the impact on others need to be carefully considered when using these techniques. The following are some possible effects of non-verbal behavior and suggestions for reflection. They are for understanding human behavior only.： **1. Space and location** -Invade personal space (such as suddenly shortening the distance) -Stand in a higher position or communicate from a top view angle - *Reflection: This may trigger the opponent's defense mechanism and destroy the foundation of trust* **2. Time control** -Deliberately extend the silence before responding -Slow down the motion - *Note: Excessive use may be regarded as manipulation rather than effective communication* **3. Micro-expression management** -Gaze that reduces the frequency of blinking -Slight tilt of the head (may be interpreted as examination) -*Reminder: There is a subtle difference between real eye contact and oppressive gaze* **4. Attitude control** -Show an "authoritative standing position" behind your hands -Asymmetric sitting posture (such as armrests) -*Risk: may create an atmosphere of unnecessary power confrontation* Research by psychologist Amy Cuddy shows that open posture does enhance self-perceived authority, but a meta-analysis in Psychological Science in 2019 pointed out that this effect may be overestimated. The real social influence comes more from： 1. Consistency: the harmony and unity of verbal and non-verbal signals 2. Empathetic ability: establish connections through mirror neurons 3. Situational adaptability: adjust behavior according to cultural background **A more active alternative：** • Establish a connection through moderate eye contact • Maintain open gesture delivery credibility • Use encouraging actions such as nodding to guide the conversation Any communication skills should be based on respect. If the goal is to exert a positive influence, it is recommended to cultivate： -Emotional awareness - Clear expression skills -Conflict resolution wisdom Mental health experts remind that long-term use of oppressive communication may lead to： ✓ Interpersonal tension ✓ Team creativity declines ✓ Distortion of self-awareness True leadership comes from the ability to stimulate the potential of others, not from creating pressure. How to balance firmness and friendliness is a interpersonal art that requires continuous practice.
