Rosenthal (1976)asked students to teach a rat to learn a maze.Some students were told they had been given a genetically engineered "intelligent" rat,whereas others were told that they had a "dull" rat.Although there were no actual differences among the rats,the "intelligent" rats learned the maze more quickly than the "dull" rats.What is the most likely cause of these results?
A) experimenter expectancy effects
B) mundane realism
C) experimental realism
D) high construct validity

The most likely cause of these results is experimenter expectancy effects, as the expectations of the students who were told they had an "intelligent" rat may have influenced their behavior and teaching methods, leading them to inadvertently give more attention and positive reinforcement to the "intelligent" rat, ultimately affecting its performance in the maze. There is no evidence to suggest that the other options (mundane realism, experimental realism, and high construct validity) are responsible for these results.
