Script Training Rationale Instance Theory of Automatization Automatic processing is fast, effortless, autonomous, stereotypic and unavailable to conscious awareness Automaticity of skills achieved by retrieving memories of complete, context-bound, skilled performance These memories are formed with repeated exposures to a consistent task (practice) (Logan, 1988) Instance Theory of Automatization Each instance of exposure contributes to the acquisition of a domain specific knowledge base when stimuli are mapped consistently on to the same responses Retrieval occurs automatically when the same stimuli from the practice environment are present Practice increases amount and speed of retrieval (Logan, 1988) 1

H: She can now name our children, which she couldn t do before without being prompted MCM Exit Interview H: But one of the biggest things that I ve noticed about M, since she started this program is that, her ability to be able to read a little more than what she could before. She now picks up signs, words. She could always read to a degree, a very small degree, the menu in a restaurant, where today i think she pretty well can read the menu as a whole and understand pretty much what s there H: She s more eager now. She looks at her mail by herself. Magazines, literature when it comes, advertisements. MCM Exit Interview H: Since she started the program. And she s much better now, talking with her friends sometimes. As an example, Monday night, her girlfriends invited her to go play golf so she went and played golf. And at first they didn t talk to her. But after a while they started to talk to her and she opened up and she just... M: Talk talk talk talk talk (laughs) H: Talking quite a bit.
