What is meant by a "perceptual map" for language and how does it develop?
What will be an ideal response?
A perceptual map forms that represents similarities among sounds and helps the infant learn to discriminate among different phonemes. These maps form quickly; 6-month-old children of English-speaking parents already have auditory maps different from infants in non–English-speaking homes, as measured by neuron activity in response to different sounds (Kuhl et al., 2006). By their first birthday, the maps are complete, and infants are less able to discriminate sounds that are not important in their own language.
