attentional spotlight
- cannot process everything in visual field - attentional
spotlight describes metaphorically how one part of field has
priority - little processing outside that area - zoom lens analogy
- reversible figures e.g. Rubin's face/vases suggest
spotlight is on an object rather than an area
- Driver & Bayliss found attention directed to
items grouped with common movement even if
they were not near each other
- idea is important as it postulates we have some
control over what we process - attention is selective
- attention involves higher cognitive processes
such as expectancy - attention can be switched
to where you expect something to appear
- sometimes have little control e.g. perceptual
load is high - attentional tunnelling can occur
- do not have complete control over where the spotlight is e.g. loud
noise or sudden movement distracts (stimulus-induced shift of
attention) - may also be affected my motivational factors e.g. hunger
