Abstract
The purpose of this study was to investigate the effect of music training on preschoolers' Performance IQ (Wechsler Preschool and Primary Intelligence Scale-Revised, 1989). Preschoolers in the treatment group (N = 15) met weekly from October 1996 through April 1997. A Mann-Whitney test on Performance IQ (scaled) gain scores by group yielded U = 67, p =.059; a Mann-Whitney test on Performance IQ (raw) gain scores by group yielded U = 65, p =.049. Regressions of IQ gain scores on age showed significantly less gain for older children in the control group (N = 15). A regression analysis showed that the relationship of Performance IQ to age was not significant for the treatment group. Slopes intersected at age 3. For 3-year-olds in this study, an intellectually stimulating environment, per se, results in a gain in the ability to perform spatial-temporal tasks.
