I only get the digest so I'll have to wait for tomorrow morning to read any more about this but we are just now covering sensation/perception in intro so of course I had to talk about this in class. Most of the explanations I have seen on tips so far do not account for the fact that two people can be looking at the dress from approximately exactly the same angle with the same lighting conditions and their first impression is opposite of the other. The fact that simultaneously two people see it differently is what needs to be explained.
Sure enough in class, about 75% of the class saw blue/black and 25% saw white/gold. They were all looking at the same time on the projection from my laptop to the overhead display, so many of the explanations about light and shadow cannot stand because the distribution was such that it would be impossible for such dramatic shifts. So far the best I was able to find online to use in class yesterday was that this is a combination effect of individual differences in perception of light and shadow--some people's first impression is that the dress is in shadow and others that it is in light and the brain the interprets the colors accordingly. I did bring in the link to the nice website here: http://www.michaelbach.de/ot/lum-adelsonCheckShadow/index.html (my favorite website for explaining illusions). This all happens along with individual differences in receptors--some people having more or less of the different receptors, particularly red and green, and THEN individual differences in how these combine for opponent processes. I don't know, that's a lot of mushy combinations that I would think would show up more often in day-to-day life than just for this one event. So I hope when I open up tips tomorrow morning I will have more to take to class on Monday :) Annette Annette Kujawski Taylor, Ph. D.
