An experimenter wanted to test the effects of music on learning by fourth grade children. To keep his work at a manageable level, he decided to introduce music into the classroom every afternoon for one week. No music would be played during the morning hours. The experimenter chose the music carefully--the music was from familiar TV cartoons, and the volume was moderate. After the week of music presentation, the students were given tests on the morning and afternoon material. Test scores for the morning material were much higher than the scores on the afternoon material. Thus, the experimenter concluded that cartoon music disrupted learning in the classroom. Do you agree or disagree with this conclusion? Justify your answer.
