Description

A dataset consisting of 38 empirical studies used in the meta-analysis of Pietschnig, Voracek, and Formann (2010) on the Mozart effect. Each study compared the spatial task performance of participants after hearing the first movement "allegro con spirito" of the Mozart sonata for two pianos in D major (KV 448) with the spatial task performance of participants who were exposed to a non-musical stimulus or no stimulus at all.
