Multiple Choice

In a classic experiment,psychology students were assigned to work either with "bright" rats or with "dull" rats,described as such by the experimenter.In a task involving learning a maze,rats arbitrarily labelled as "bright" learned the maze faster than did rats arbitrarily labelled as "dull." The experimenter suspected that the psychology students with "bright" rats took the learning task more seriously,and this was reflected in their rats' performance.This finding illustrates how:
