Abstract

Firmino and Bueno (2008) found that retrospective time reproductions decreased in functionof the increasing of interkeys distances in 20s-long musical stimuli. If such tonal pathwaysincluded intermediate keys, the temporal reduction impact was smaller. The authors proposedthe expected development fraction model (EDF-model) with both an implicit working memory(IWM) component representing a subsequent psychoacoustic process through spatialtemporalkey coordinates relative to the immediate stimulus regularities and a semanticmemory (SM) representing the high order cognitive structure of tonality internalized throughlong-term passive exposure. After such induction, a comparison process obtains the perceivedIWM-duration being shorter than the expected SM-duration, implying a disproportion. Areproduction process applies such fraction to the IWM-duration, leading to timeunderestimation. In order to verify the EDF-model’s presuppositions regarding reversepathways, this work found that 20s-long music unfolding distant reverse pathways elicitedshorter time estimations than close ones.
