The Mozart effect: questions about the seminal findings of Rauscher, Shaw, and colleagues

Seminal evidence for the Mozart effect was presented by Rauscher, Shaw, and colleagues in 1993 and 1994. A critical evaluation of their methodologies and interpretation of findings raises questions that must be answered before this evidence can be regarded as valid. We discuss issues such as their scoring of the Stanford-Binet Intelligence Scale, the experimental design used in their 1993 study, the validity of their 1993 IQ measure, the duration of the Mozart effect, their choice of experimental tasks in relation to predictions of the trion model of neural functioning, and the statistical analyses and interpretation of results in the 1993 and 1994 studies.
