EFFECTS OF CLOSE AND DISTANT REVERSE TONAL PATHWAYS IN MUSICAL STIMULI ON RETROSPECTIVE TIME REPRODUCTIONS
AbstractFirmino 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-modelâ€™s presuppositions regarding reversepathways, this work found that 20s-long music unfolding distant reverse pathways elicitedshorter time estimations than close ones.
