Document Summary

It is the taking possession by the mind in clear and vivid form it implies withdrawal form some things in order to deal effectively with others . A person listens to two different messages, one message coming into one ear and a different message coming into another ear. However, unattended ear is being processed at some level: change in gender is noticed, change to a tone is noticed. Attention allows us to focus on some things at the expense of not focusing on others. Where does the attention filter occur: early in processing, later in processing. Early selection model: broadbent"s filter model (bottleneck model) (1958) Intermediate selection model: treisman"s attenuation theory (leaky filter model) (1964) Late selection model: e. g. mckay (1973) Filter is very early, cannot account for dear aunt jane and name, meaningful words can creep in. Early-selection model: filters message before incoming information is analyzed for meaning.
