what is divided vs selective attention
divided- paying attention to more than one thing at once
selective- focussing on one specific thing
why do we need attention
because there is too much info available to process it all, we have finite capacity
what is exogenous attention
guided by enviroment
what is endogenous attention
guided by the individual
what is interattentional blindness
we often do not perceive an object/ event if we do not attend to it
what is change blindness
when scenes change between two discrete views we are not sensitive to large differences between scenes. observers fail to notice significant changes in a visual scene
what are continuity errors
a mistake which can be due to inattentional or change blindness in films where there is a visible inconsistency between scenes
how can attention be related to a spotlight
we have selective attention/ can only pay attention to so much at one. cant pay attention outside of spot light
how can attention be compared to glue
focussed attention binds separate visual features into a coherent perceived object
what is feature integration theory
an explanation of how we go from seeing seperate features to whole objects.
preattentive stage- features are free floating
focussed attention stage- features are bound together
what type of vision is required to percieve fine detail
central vision
how is eye movement involved in directing attention (stimulus salience)
we direct our eyes to the most salient object in the scene (that pops out the most)
what is the criticism of stimulus salience in eye movement directing attention in real life
in real world, eye gaze is directed to the right place and right time to guide actions (this may differ in neurodivergent conditions e.g. autism)
what is monotrophism
cognitive style characterised by an intense, narrow focus of attention on a small number of interests at a time. seen in autism
what happens in a monotrophic mind
fewer interests are aroused and they attract more processing resources. it is harder to deal with things outside of these interests.
how can attention enhance perception
we respond faster to attended objects, attention enhances physiological responses
