Selective Attention

In 1958 Broadbent proposed a filter model of attention which attempted to explain why only some but not all aspects of the stimulus environment reached attention. Following Broadbent's lead, several variations on this model were proposed (Treisman, 1964; Deutsch & Deutsch, 1963).

Question 1: Sketch out all three models indicating:

a. What each model assumes about the sort of processing that takes place with respect to both targeted and non-targeted stimulus information.

b. Describe at least one experiment which supports Broadbent's model (indicat9ing, of course how the data support the model.)

Question 2: Based upon your assigned readings, class notes, outside readings etc.

a. Select and discuss at least two experiments that led to the rejection of Broadbent's model. (You may use but are not limited to Grey and Wedderborn, 1960; Treisman, 1964; Corteen and Wood, 1972; Mackay, 1973 etc.)

b. Explain how attenuation or late filtering models handle the data from the experiments you just described above.

c. Evaluate the merits of choosing between the Treisman's and Deutsch and Deutsch's model.
