Document Summary
Focal attention - controlled internally by intentions and goals. Automatic attention - controlled externally by sensory events that demand attention. Before choose what to attend to, how do we select it on a basis without attention. What information can be gotten from stimulus without attention so that we know to attend to it. Based on physical qualities like colour or direction of movement [meaning of object is not considered]? or abstract qualities like name or categories [select based on meaning] Choice can be governed by what is out there in the world. Behaviourist view; behaviour controlled by things in world. Early is soon after stimulus occurs; before much processing has occurred. Shape, size, colour, direction of movement generated; not meaning. Filter means only one stimuli will be processed for meaning and other stimuli will be ignored; physical characteristics may be processed.
