The Lewin, Lippitt and White study of leadership and "social climates" revisited.

Sparked by the 100th Anniversary of Kurt Lewin's birth, this paper re-examines a classic 1939 study by Lewin, Lippitt, and White, of three leadership styles and the resulting different social climates, that is, autocratic, democratic, and laissez faire. A gradual extension of Lewinian field theory to include unconscious motivations in individual and in group behavior has served to broaden the already significant influence of this research on the behavioral sciences. Two recent developments moved me to write this communication: (1) The 100th Anniversary in 1990 of Kurt Lewin's birth (Maccoby, 1992); and (b) a broadening of Lewinian field theory to encompass unconscious motivations (White, 1992).
