(1971) â¢ Discriminability was measured by an increase in sucking rate toa second speech sound after habituation to the first sound. â¢ Recovery from habituation was greater when the two stimuli were from different adult phonemiccategories than when they were from the same category. Eimas et al.1971) reported that infants, like adults, demonstrate categorical ppp p perception for speech sounds. To explain this they proposed that infants are equipped with innate, speech-specific, phoneticfeature detectors tuned to the range of phonetic contrasts used in the worldâs languages.
Lesson Summary. The language acquisition device is a hypothetical tool in the brain that helps children quickly learn and understand language. Noam Chomsky theorized the LAD to account for the rapid speed at which children seem to learn language and its rules.LAD later evolved into Chomsky's greater theory of universal grammar.eep in mind that the LAD is a theoretical concept. There isn't a section of the brain with 'language acquisition device' printed on it and a big switch to turn on and learn a new language.
