The ability to discriminate speech sounds. The ability to remember a sequence of speech sounds in the correct order. The ability to discriminate between sequences of speech sounds The ability to compare a sequence of speech sounds to a model that has been stored in memory. The ability to make discriminations among intonational patterns. 1. The ability to attend specifically to speech sounds Infants show a greater interest in human speech rather than other noises. Infants prefer their own mothers voice to that of other womens voices. 2. The ability to discriminate between speech sounds The older an infant gets the more difficulty she will have in discriminating speech sounds that do not occur in her native language. It is a childs environmental experiences that will shape her discrimination abilities. 3. The ability to remember a sequence of speech sounds in the correct order Short term memory plays a key role in this perceptual ability. Children dont produce sounds in isolation, but is in conjunction with other sounds. 4. Discriminating Between sequences of speech sounds Within the 1st 6 mos. infants can discriminate among sounds and sequences of sounds. Some words are identical except for one sound. 5. Comparing Sequences of Sounds Stored Models Sometime after 6 mos. she is beginning to understand words. This means that the child is developing an auditory sequence meaning association. 6. Discriminating Intonational Patterns. Intonation = duration, fundamental frequency, intensity It is thought that is the intonational patterns of speech that help her parse out 1st phrase boundaries, 2nd word boundaries. Building a Conversation Infant-Adult Interactions/Joint Attention Phase 1 The caregiver directs the infants attention toward an object, person, etc. Phase 2 The child begins to demonstrate joint referencing by pointing to an object and looking for a response....
