Attention Flashcards
Who devised the filter model of selective attention?
Broadbent
Explain the filter model
Early selection model - filtration occurs before the stimulus is processed for its meaning
Physical characteristics of the input e.g. volume serve as the criteria for filtering
What is the limitation of the Broadbent model?
doesn’t account for the cocktail party effect where one can hear their name across a noisy room in a low volume
Who devised the attenuation theory of selective attention?
Treisman
Explain the attenuation theory of selective attention
Instead of strictly filtering out unattended information, this model weakens or attenuates it
two stage filtering mechanism
What is a dictionary unit?
certain words that have a lower threshold for capturing our attention
Who devised the late stage model of selective attention?
Deutsch and Deutsch
Explain the late stage model of selective attention
stimuli are analysed for their meaning before any filtration takes place
selection is made after the stimuli have been comprehensively processed for meaning, implying a more in-depth, post-cognitive filtering
Who devised the multimode model of selective attention?
Johnston and Heinz
Explain the multimode model of selective attention
people can switch between early and late selection based on task demands and individual decisions
