Document Summary
Jan 22: limited selection of everything that is available, when you focus on something, you withdrawal attention from something else, attention under different theoretical umbrellas. What is attention: attention as a mental process, process of concentrating effort on a stimulus, selective attention, attention as a limited mental resource, the limited mental energy that powers the mind. Selective attention: attention is limited, must select relevant info to attend to and combine, massive info + limited capacity = selective attention. Information processing model: sensation perception mental representation. Cocktail party effect: we can attend to only one conversation among many, but will notice critical info, examples: name, favourite sport team etc. Dichotic listening experiment: test when does cocktail party effect occur, shadowing- verbally saying what is being attended to in the one ear, suggests some info is processed to some extent, but is filtered, not interpreting unattended to message.
