Document Summary

Filter is located before long term memory. Filter located after entry into long term memory. Evidence reduced detection accuracy on unattended channel (treisman & Study divided attention instead: some phenomena are not predicted by either theory, shadowing tasks investigate attentional filtering (try to exclude distracting material) Is it possible to distinguish between weak semantic activation (early selection) and brief semantic activation (late selection) on the unattended channel: how well can we distribute attention across multiple channels, divided attention (moray, 1970) Anderson & stenman, 1975: early selection vs. late selection means. Auditory signal detection pure tone stimuli (brief, Selective monitor for targets on one channel only. Large cost of simultaneous detection (rate of correct response: and << or) -> and deficit predicted by late. Late selection by pertinence and compete to get through the filter: predicts and << or because two simultaneous targets will both be selected, doesn"t predict or < sel because if two targets are not present, no.
