Unformatted text preview: Cognitive­Interactionist Cognitive­Interactionist Model of Language Acquisition 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) ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
