PSY247: illusions
Cards in this deck (3)
- 1explain the Bistable figures illusiondemonstates that perception is not always automatic, does involve top-down processes. actively seeks solution from stimulus
- 2explain size illusions like ponzo and muller lyer.they are both cases of misaplied constancy scaling. our brain is used to interpreting the retinal size of an image in relation to depth and distance. and so some lines just seem too big for their context.
- 3explain shape and orientation illusions; like the Hering illusion.they could also be a case of misapplied scaling constancy. However they more likely result from 'perceived repulsion of similar orientations'; our over estimation of acute angles. when lines of similar orientation are presented we presume the size between them as bigger than reality. this causes the line to curve as more acute angles get 'bigger'
