SPCH 1000 Lecture Notes - Lecture 2: Phonological Development, Communicative Competence, Linguistic Competence
Document Summary
Infancy development- when babies begin gazing into the eyes of their caregiver and become sensitive to the emotional tone of voices. Phonological development- when babies babble, they began to learn sounds and the patterns of those sounds: babies may comprehend sounds, but they are not always able to produce the sounds. Semantic development- young children begin to relate words to meanings. Language is marked by productivity, language is symbolic, and language can be displaced. Productivity: make new utterances combine/expand forms already know to hear something you never heard before. Semantics (symbolism): language represents ideas, events, and objects. Displacement: messages are not always tied to the real meaning. Broca"s area is in the left frontal region of the brain. Broca"s aphasia is when the broca"s area is damaged and a person will have difficulties with pronunciation. Wernicke"s area is in the posterior left temporal lobe. Damage to this area produces an aphasia that is characterized by fluent speech and poor comprehension.
