At what age do foetuses show changes in heart rate as a direct response to auditory stimuli
26 weeks
Explain the findings of DeCasper & Spence
Pregnant women read a 3 min story every day for the last 6 weeks of their pregnancy.
Newborn infants preferred hearing the familiar story to an unfamiliar story, even when read by a stranger. Babies in a control condition showed no preference.
Explain perceptual narrowing
Infants gradually exchange their limitless potential for processing all types of information in return for quicker, greater expertise in processing the kind of info they tend to see in their particular environment
