PSY 447LEC Lecture Notes - Lecture 7: Crossmodal, Cochlea, Low Frequency
Document Summary
Dolschied et al. (2014) - prelinguis tic infants are sensi ti ve to space-pi tch associations found. What we"re used to: height metaphor (high pitch vs. low pitch) Infants are sensitive to height-pitch mappings pre- linguistically. Height-pitch is reflected in most languages, therefore we see it most often in research. If space-pitch associations are innate, infants should prefer congruent relationships. But, if associations are driven by environment, dutch infants should prefer height over thickness relationships. Due to the roughly linear place coding of pitches in the cochlea, from apex to base. Preferential-looking paradigm: follow infants" tendency to look at certain situations *particularly when the presented stimuli matches their expectations. Infants watch vertical tubes changing thickness on a screen, accompanied by the sound of a sliding whistle. Infants watch ball moving up and down a screen, accompanied by the sound of a sliding whistle. Infants looked at 3 congruent and 3 incongruent scenarios (in random order)
