Document Summary

Selective: restricted to a subset of the possible stimuli: broadbent"s filter model: dichotic listening task, selective filter for thing paying attention to. Selection in space: cue: stimulus that might indicate where/what a subsequent stimulus will be (valid, invalid, neutral) Exogenous/peripheral: at the desired final location of attention. Endogenous/symbolic: located in/near current location of attention: stimulus onset asynchrony (soa): time dif btwn onset of one stimulus and another. Endogenous cues take more time than exogenous cues to attract attention: value-driven attentional control: stimuli that have acquired value attract attention. Training phase, testing phase: spotlight model: attention restricted in space and moves from one point to the next, areas w/in the spotlight receive extra processing. Top-down (endogenous) control: voluntarily directed towards stimuli relevant to current goals, focus during test. Bottom-up (exogenous) control: involuntarily captured by things that stand out, hearing fire alarm.
