Document Summary

Serial bottlenecks: serial bottlenecks points at which it is no longer possible to continue processing everything in parallel. Corbetta and shulman argue that somewhat different brain systems control goal-directed attention versus stimulus-driven attention. Goal-directed attentional system is more left lateralized, whereas the stimulus-driven system is more right lateralized. The attenuation theory and the late selection theory: treisman modifies broadbent"s model, hypothesized that certain messages would be attenuated (weakened) but not filtered out entirely on the basis of their physical properties. In a dichotic listening task, participants would minimize the signal from the unattended ear but not eliminate it: an alternative explanation was offered by j. It is necessary to search through a visual array for an object only when a unique visual feature does not distinguish that object. Judgments made faster when people didn"t have to shift attention between objects: the advantage of the within-object effect disappeared when the stimulus was present for only the brief period.
