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
<i>Vision Research</i>) 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. </p>

<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:times">To summarise various contributions, here is a list of factors modulating responses to visual illusions and thus contributing to individual differences:<span></span></span></p>
<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:times"> </span></p>
<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:times">Age. Simon
</span><span lang="EN-US" style="font-family:times">Rushton<b> </b></span><span style="font-family:times">has already mentioned Piaget (Piaget et al., 1942). There is also more recent work (</span><span style="font-family:times">Doherty et al., 2010</span><span style="font-family:times">)<span></span></span></p>
<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:times">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.<span></span></span></p>
<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:times">Autism spectrum. Many studies on this (best known study by Happé, 1996; recent review in Gori et al., 2016)<span></span></span></p>
<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:times">Culture. The Himba in Namibia have weaker illusions, may focus more on local info (</span><span style="font-family:times">de Fockert et al., 2007</span><span style="font-family:times">).
Also Asians differ from Westerners, showing greater sensitivity to context in size illusions (</span><span style="font-family:times">Doherty et al., 2008</span><span style="font-family:times">).<span></span></span></p>
<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:times">Developmental dyslexia. Slaghuis et al. (1996) using Ternus stimulus, found a reduction of group motion.

<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:times">It has also already been mentioned that recent work found weak correlations between visual illusions in a sample of over 100 people (</span><span lang="EN-US" style="font-family:times">Grzeczkowski
