Robert F. Bales observed these entities using a three-dimensional space that captured images like “dominance” and “friendliness” in the SYMLOG analysis method. Susan Wheelan’s integrated model of these entities’ development builds on a model whose five stages include storming, norming, and performing, (15[3]-5[1])developed by Bruce Tuckman. Donald Campbell contrasted social exchange theory with a model of these entities (15[1])that he dubbed “realistic (*) conflict theory.” An experimental technique (10[1])created to study these entities (10[1])assigned subjects randomly after showing them paintings by Klee (“clay”) or Kandinsky. That “paradigm” for creating the “minimal” (10[1])form of these (10[2])entities was devised by Henri Tajfel (“TY-fell”). For 10 points, situations like “Vladimir’s choice” illustrate the favoritism shown towards the (10[1])“in-” (10[1])type of what (10[1])social formations? ■END■
