Another failure to generalize the Mozart effect

Several studies have not replicated Rauscher, Shaw, and Ky's 1993 finding that 10 minutes of exposure to Mozart piano music temporarily enhanced performance on three spatial reasoning tasks. Later Rauscher and Shaw argued that enhanced performance is unlikely unless three conditions are met. The present study was designed to meet those three conditions. 36 adults were exposed to one of six listening orders and one of six test orders. Listening and test orders had no systematic effect on spatial reasoning performance. A one-factor, repeated-measures analysis of variance yielded no significant difference on spatial reasoning performance after listening to classical music, jazz, or silence. A reanalysis, using only those items most likely to tap spatial reasoning, fell short of significance, and mean scores were in the direction opposite to that hypothesized. These results were inconsistent with studies that have supported a Mozart effect.
