Infants aged 2 and 6 months were tested with the precedence effect, an auditory phenomenon involving sound localization. Each infant was tested with two types of stimuli: sound from a single loudspeaker and precedence‐effect sounds produced by the same sound put through two loudspeakers, with one output leading the other by 7 msec. Older infants localized precedence‐effect stimuli as they did single‐source stimuli, indicating that they perceived this phenomenon as expected. Two‐month‐olds turned their heads toward single‐source sounds, but did not localize precedence‐effect sounds, suggesting that that more difficult perceptual task had not been achieved at this age. In general, headturning toward sound proved far more difficult to elicit in younger infants. A click train was ineffective, but a tape‐recorded human voice elicited above‐chance low‐level turning. The developmental changes in auditory behavior are discussed in terms of the rapid growth of the auditory cortex.
