Abstract:
Schellenberg (2004) reported results from a study that measured IQ scores of a large sample of 6-year-olds before and after they were assigned at random to one of four groups. Two groups received music lessons (keyboard or voice) for a year. Two control groups received drama lessons or no lessons. Compared with the control groups, the music groups had larger increases in IQ. Steele (2005) criticizes the decision to collapse the two music groups in the sta-tistical analyses, whereas Black (2005) criticizes collapsing the two control groups. In both cases, the decision to collapse the groups was motivated conceptually as well as empirically. The results complement established findings that attending school raises IQ. Out-of-school activities appear to exaggerate this effect depending on the degree to which they resemble school.
