Muller Lyer – Distance scaling, perceived as further away but the same size, therefore your brain perceives it as larger even though it’s the same size on the retina. (Size-distance scaling) (This is Gregory’s view on the illusion, and can be refuted with the dumbbell version of the Muller Lyer illusion that removes depth as a factor) Another (DAY) theory is local versus global cues, even though parts of the shape are aligned, the whole shape is not aligned, and therefore the brain takes an average of the two which results in a slightly misaligned Navon also investigated local versus global theories HHHHHH H HHHHHH H HHHHHH (What is that letter?) Time taken to record answer is collated, to see whether local conflicts with global cues. Local cues reaction is slower than global cue recognition. Macrae and Lewis 2002 They can be used to bias processing level. (Face recognition) Faces are looked at holistically, but they would not recognise the faces globally aa second time if they were asked to pay attention to local cues only. Global cues are much more useful?*
