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 labeled as "bright" learned the maze faster than did rats arbitrarily labeled 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:
A)expectations can influence observations.
B)observations can influence measurement.
C)expectations can influence reality.
D)observations can influence reality.
