Dr. Swathi Vanniarajan Information Processing Approach to Information Processing Approach to Language Acquisition Language is a huge memory network. Language acquisition is a process of moving from controlled to automatic processing. Language is a rule like behavior. Acquisition is a four stage process: perception, processing, storage, and retrieval. Parallel distributed versus serial processing What is innate? Language is a huge memory network Language is a huge memory network Language is encoded in our memory in the form of neural synapses. It is both localized and dispersed all over the memory network. There may not exist a critical period for learning. It is possible to grow nodes all through your life. You use it or lose it. Language acquisition is a process of moving Language acquisition is a process of moving from controlled to automatic processing. There are three kinds of memory systems: sensory registers, shortterm memory, and longterm memory
Input Sensory registers Shortterm memory Longterm memory Sensory registers Sensory registers Not all information gets processed Unless transferred to shortterm memory or rehearsed, the information will disappear from sensory registers from a fraction of a second to a maximum of 4 seconds. The information is still raw. Shortterm memory Shortterm memory Also known as working memory This is also the place of consciousness or what is called attention. Once the information comes to working memory, if attended to, it gets interpreted. Encoding, interpretation, and organization take place in working memory. Shortterm memory Shortterm memory Working memory Responsible for storage and processing. Reading – pronoun computation – storyline Plus or minus 7 chunks of information Storage and processing – a trade off Controlled means a great deal of attention is given to details Automatic processes require very minimal attention. Language Acquisition Language Acquisition Language acquisition is a process of moving from controlled to automatic processing. Emotional memory (affect) can speed up (facilitate) or slowdown or even inhibit the process. Language is rulelike behavior Language is rulelike behavior Chomsky: language is a rule governed system. Cognitive parsimony (economy) Cognitive psychologists: Brain mechanisms do not need cognitive parsimony – they have enough resources – Language is a rulelike system built on associative connections among neurons Acquisition is a four stage process: perception, processing, storage, and retrieval.
Perception is what you perceive and process (noticing) Processing is important – there may be both conscious and subconscious processing Storage – you need to remember Retrieval – successful retrieval of information in real time Parallel distributed processing Parallel distributed processing We process information at multilevels all the time – it is possible we process information at the discourse, syntactic, morphological, phonological, pragmatic, and semantic levels at the same time – also, any new learning affects what has already been learnt and the network will undergo what is called restructuring (this can involve backsliding also since the learner needs to consolidate his/her learning) What is innate? What is innate? Ability to learn iswhat is innate (this includes ability to perceive and organize information) ...
