experiments diffi cult to explain based on Broadbent’s fi lter model of attention? - Describe Treisman’s attenuation theory. First indicate why she proposed the
theory, then how she modifi ed Broadbent’s model to explain some results that
Broadbent’s model couldn’t explain. - Describe MacKay’s “bank” experiment. Why does his result provide evidence
for late selection? - What is the fl anker compatibility task? How have experiments using this task
shown how attention is affected by load and by the nature of task-irrelevant
