Influence of Global Structure on Musical Target Detection and Recognition

subject

description

The present study adapted a paradigm used in visual perception by Biederman, Glass, and Stacy (1973) and analyzed the influence of a coherent global context on the detection and recognition of musical target excerpts. Global coherence was modified by segmenting minuets into chunks of four, two, or one bar. These chunks were either reordered (Experiments 1, 3, 4, 5) or transposed to different keys (Experiment 2). The results indicate that target detection is influenced only by a reorganization on a very local level (i.e. chunks of one bar). Context incoherence did not influence the recognition of the real targets, but rendered the rejection of wrong target excerpts (foils) more difficult. The present findings revealed only a weak effect of global context on target identification and only for extremely modified structures. Cette etude reprend un pardigme utilise dans la perception visuelle par Biederman, Glass, et Stacy (1973) pour analyser l'influence du contexte global sur la detection et la reconnaissanc...
