Physical characteristics of messages are used to select one message for further processing and that all others are lost

What is Treisman's Attenutation Model? (1960)
Unattended messages are processed weakly
5 of 13
What did the Late Selection Model argue? (Deutsch and Deutsch, 1963)
all stimuli get processed in full, with the crucial difference being a filter placed later in the information processing routine, just before the entrance into working memory

What is load theory?
Locus of selection is both early and late, it depends on how hard the task is

What is perceptual load?
Refers to the complexity of the stimuli in the display
9 of 13
What is cognitive load?
The load that the task goals and prioritises place on working memory
10 of 13
What is biased competition?
Stimuli compete for limited capacity in multiple system, this competition can be biased in favour of relevant stimuli and so can be selected at multiple loci
11 of 13
What is early selection?
Locus of selection is at early stages of processing and so unattended stimuli is not fully processed
12 of 13
What is late selection?
Attention operates only after stimuli have been fully processed
