To assess an infant's attention to sound, researchers often use a method called high-amplitude sucking. Describe how this method is used.
What will be an ideal response?
In this method, infants are given a nonnutritive nipple to suck, and it is connected to a sound-generating system. The researcher computes a baseline high-amplitude sucking rate in a one-minute silent period. Following the baseline, presentation of a sound is made contingent on the rate of high-amplitude sucking. Initially babies suck frequently so the sound occurs often. Gradually they lose interest in hearing the same sound, so they begin to suck less often. Then the researcher changes the sound that is being presented. If the babies renew their vigorous sucking, the inference is that they have discriminated the sound change and are sucking more because they want to hear the interesting new sound.
