Document Summary

Cognitive neuroscience: study of connection between brain activity and cognitive processes; ex: perception, thinking, language, and memory. **evidence of consciousness even when lack ability to communicate. Dual processing: we evaluate our environment both consciously and unconsciously. Blind sight: respond to visual stimulus without consciously experiencing it (**disorder) Functioning visual action track because can grasp it. Functioning visual perception track: can see and recognize objects but difficulty pointing toward or grasping. Ball example; person consciously can"t see, but will make appropriate hand gesture for ball size. Selective attention: focus conscious awareness on a particular stimulus. **if you don"t attend to something, you won"t remember that thing. Accidents (car); when engaged in task, blink less. Cocktail party effect: can ignore all other incoming info, but become aware of your own name. Inattentional blindness: failing to see visible objects when our attention is directed elsewhere (black/white shirts & gorilla) Change blindness: failing to notice changes in the environment (person swap)
