[visionlist] immunity from illusions

Just to add to this interesting discussion that, although Grzeczkowski et al. (2017) found only one significant correlation between visual illusions out of 15 comparisons, our latest paper (to be published in the same special issue of Vision Research) shows a strong interindividual relationship between spatial and temporal contextual effects in motion perception. Specifically, our data show a strong positive correlation between individual estimates of the direction aftereffect and direction illusion/repulsion. In the same paper, we also report a weak, but ultimately non-significant, correlation between the direction and tilt aftereffects.

Subject: Re: [visionlist] immunity from illusions

To summarise various contributions, here is a list of factors modulating responses to visual illusions and thus contributing to individual differences:

Age. Simon Rushton has already mentioned Piaget (Piaget et al., 1942). There is also more recent work (Doherty et al., 2010)
Anatomy. Size illusions correlate to size of V1 (Schwarzkopf et al., 2011). I imagine the individual differences reviewed by David Peterzell (2016) may also relate to different sensitivity to visual illusions.
Autism spectrum. Many studies on this (best known study by Happé, 1996; recent review in Gori et al., 2016)
Culture. The Himba in Namibia have weaker illusions, may focus more on local info (de Fockert et al., 2007). Also Asians differ from Westerners, showing greater sensitivity to context in size illusions (Doherty et al., 2008).
Developmental dyslexia. Slaghuis et al. (1996) using Ternus stimulus, found a reduction of group motion.
Schiophrenia (review in Notredame et al., 2014, see also link in Chris Sims post to an article by Laura Sanders).
Schizotypy. Not sure whether this should be listed separately from schizophrenia (Partos et al., 2016).
Sex. In relation to males having a stronger lateralisation (Rasmjou et al., 1999)

It has also already been mentioned that recent work found weak correlations between visual illusions in a sample of over 100 people (Grzeczkowski et al., 2016) thus suggesting that maybe some variability is idiosyncratic.

Are there more factors to add to the list?
