Document Summary
* view james" quote: describes what attention achieves but not what processes or mechanisms produce these effects. Early studies used a set up called dichotic listening which involves two different inputs in each ear. they are told to pay attention to the attended channel and ignore the unattended channel . To make sure the participants were paying attention one gave the task of shadowing reciting the speech word for word after it is said to them and remember little from the unattended channel. They discovered the same pattern along for visual inputs. hence, people are not altogether oblivious to the unattended channel because apparently the physical attributes of the channel are heard even if they"re oblivious to it"s semantic context. The central early theory was called the bottleneck theories - which suggest that you erect a lter that shields you from potential distractors. Ltered out and so goes on to receive further processing.
