Emily Moonan 1. List some of the explanations for why infants prefer infant-directed speech (IDS) as compared to adult-directed speech (ADS). What do you think of these explanations? • Because they are more sensitive to acoustic features, like high pitch, long pauses, slower speaking duration, repetition, etc. • Because IDS has more emotion in it than ADS (can hear the “happy” or “sad” in speech) 2. How does mother’s use of emotional intent change across the infant’s development? Infants that are 1.5 to 4 months old pay close attention to slow IDS, even if the pitch is the same as when it is spoken in a normal duration. But, once the infant is 8 months old, he/she does not show any change in attention when something is said in a normal or slow way. A study found that during the first few months, mothers use a comforting tone when interacting with their infant. Then, at around six months, the mother begins to express more affection when interacting.
