Document Summary
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 two different stimuli. 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. Inputs -> sensory store -> selective filter (based on physical properties) (unattended message is completely ignored at this stage) -> bottleneck -> higher level processing -> working memory. Listening to two stimuli at once but focusing on only one. The content of the other stimuli was completely lost. Attentional bottleneck: getting the stimulus from sensory processes to memory processes requires attention. spotlight model of attention: attention is restricted in space and moves from one point to the next.
