Abstract:
Schellenberg (2004) reported that music lessons increase the IQ of children more than comparable nonmusical activ-ities do. However, this conclusion was based on a comparison that pooled two music groups (keyboard and voice) and two control groups (drama and no lessons). Pooling the controls negates the value of the drama group as a control for nonspecific factors. In a reanalysis, contrasts with the drama group were examined. They showed that the IQ of each music group following lessons did not differ significantly from those of the drama group. Moreover, increases in IQ for the music groups, separately and pooled, also did not differ significantly from those of the drama group. Thus, the hypothesis that music lessons specifically enhance IQ is not supported.
