PSY387H5 Lecture Notes - Lecture 5: Hear Music, Xxxo, Implicit Memory
Document Summary
300 hz < 400 hz: after 6 months, it"s impossible to study attentive responses to music (2 methods, preferential looking (sometimes combined with previous exposure/habituation, procedures with infants, conditioned head-turn, preferential looking. Infants and contour: 9-11-month-olds- perceive and classify melodies on the basis of their contour. Infants can detect when a melody is shifted in pitch (transposed) and when its intervallic structure is changed (same contour) Infants discriminate changes in tempo and small changes in pitch: 3-tone rhythms were x xx vs. xx x, 4-tone rhythms were xx xx vs. xxx x, sequences changed in pitch and tempo from presentation to presentation. Infants succeeded at both tasks- they classify tone sequences on the basis of rhythm. Infants were successful only when the silent increments occurred within a group. Infant-directed speech is more like singing than it is like adult-directed speech. Id speech- greater pitch range, more rhythmic and repetitive compared to ad speech.
