Perceptual Narrowing - CORRECT ANSWER - - Face perception is shaped by
experience
- Infants become face specialists, better at discriminating amongst the kinds of faces that are
frequently experienced in their environments
Auditory Perception - CORRECT ANSWER - - Begins prenatally
- Well developed at birth (mid range, localization reflex)
- Adult like by ~ 6 months (frequency range, intensity, advanced localization)
Results Related to Music Perception - CORRECT ANSWER - - Changes in beat
(newborns in their sleep)
- Changes in melody (~7 months, relative & some absolute pitch)
- Irregular musical phrases (4 months, e.g. clipped Mozart Minuets)
- Culture-specific rhythm patterns (e.g. Western vs Balkan)
Rhythm Matching - CORRECT ANSWER - - Infants can make melodic perceptual

Cross-Modal Perception Methods & Results - CORRECT ANSWER - - In addition to

straightened
- Birth to about 5-7 months
Babinski Reflex - CORRECT ANSWER - - Stroke bottom of foot
