Experimental Generation of Interpersonal Closeness

Instructions to Subjects Included With Task Slips Packet

This is a study of interpersonal closeness, and your task, which we think will be quite enjoyable, is simply to get close to your partner. We believe that the best way for you to get close to your partner is for you to share with them and for them to share with you. Of course, when we advise you about getting close to your partner, we are giving advice regarding your behavior in this demonstration only, we are not advising you about your behavior outside of this demonstration.

Principles of Adult Behavior

Be patient. No matter what.
Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.

Laugh at yourself frequently.
