Cognitive construction of <strong>categories</strong>: phonetic<br />
perceptual prototypes<br />
• Newborn babies have good discrimination of simplypresented<br />
“foreign” phonemic contrasts<br />
• They lose this ability as their own language develops.<br />
By 10-12 months of age, they tend only to<br />
discriminate those contrasts that are phonemic in<br />
their native language(s).<br />
• Kuhl: By 6 months of age, babies respond to classes<br />
of sounds (e.g. vowels, fricatives) spoken by different<br />
people as if they are all the same.
