Document Summary
Help to organize the flow of info. An event with greater perceptual salience or importance (event is highlighted) Salient melodic event (such as a high note) When note was accented every 3rd note, most accented the downbeat by tapping harder &/ or longer. The notes in the previous examples were equally loud. Perceived accentes need not have a physical correlate. They can be generated by our minds. A - pair an ambiguous rhythm with bouncing to either every 2nd beat or every 3rd beat for 2 min. B - examine 7 month old infants preference for disambiguated stimulus. Bouncing reinforced whether it"s on 2 or 3 beats. Either duple or triple meter during testing. This is either congruous or incongruous depending on whether the baby was bounced with the same or different meter during training. Bouncing affected baby"s ability to remember beat. Infants bounced in synchrony were more likely to help. Infants out of synchrony were less likely to help.
