Extinction of conservation by observation may be caused by social pressure. In order to demonstrate this, 2 variables were manipulated: the model's age (the model was a 4- or 7-year-old child, or an adult) and the model's absence or presence during both observation and posttest. Second-grade children who had succeeded on pretests involving liquid conservation observed a nonconserving model and were subsequently retested. Regression to nonconservation was obtained only among some of the children who had been submitted to maximal pressure in the presence of an adult model.
