PSYB51H3 Chapter Notes - Chapter 7: Visual Search, Zoom Lens, Attentional Shift
Document Summary
Chapter 7- attention and scene perception: retinal array contains far more information than we can process, attention is not a single thing, and it does not have a single locus in the nervous system. In this chapter we will be concerned with selective attention, the ability to pick one (or a few) out of many stimuli. After that, the effect of the cue levels off or declines a bit. Symbolic cues take longer to work, presumably because we need to do some work to interpret: we are built to get information from the gaze of others. The spotlight of attention: attention could be deployed from spot to spot in a number of ways. It might move in a manner analo- gous to the movements of our eyes. When we shift our gaze, our point of fixation sweeps across the inter- vening space.
