Document Summary
Inattentional blindness= a failure to notice, or at least to report, a stimulus that would be easily reportable if it were attended. Attention= any of the very large set of selective processes in the brain. Selective attention= the form of attention involved when processing is restricted to a subset of the possible stimuli. Divided attention= splitting attention between 2 different stimuli. External= attending to stimuli in the world. Internal= attending to one line of thought over another or selecting one response over another. Overt= directing a sense organ toward a stimulus, like turning your eyes or your head. Covert= attending without giving an outward sign you are doing so. Try to understand the cocktail party effect; how can we concentrate our attention on one conversation and ignore all other conversations. Broadbent used dichotic listening tasks to test the cocktail party effect. Given two streams of information in the two ears, and are asked to only pay attention to one.
