She and Matt Brown, Gwen Jewett, Alex Gilbert, James Hills, Kimberly Kaye, Heather White and a number of other people I'm not particularly interested in, share some concerns about communication standards on the web. Social communication standards, that is, not TCP/IP, HTTP and the like. They find they get to know just a little bit too much detail about their 'friends' lives, and point out how people can 'miss behave' on facebook. I wasn't aware that that is very particular to social websites. Apparently they rather have their friends hide much of their personal lives, interests and likes, and are not so keen on knowing what their friends think of things. They languish for the rules of social engagement of the past century. Well, in the new rules they are welcome to. Everybody has their own tastes, and if you don't like knowing about me, good for you!

J.; Dodd, Michael D.; Enns, James T.</p>
<p><i>Journal of Experimental Psychology: Human Perception and Performance. Vol 35(1), Feb 2009</i>, 133-145.</p>
<p>The authors describe a new visual illusion first discovered in a natural setting. A cyclist riding beside a pair of sagging chains that connect fence posts appears to move up and down with the chains. In this illusion, a static shape (the chains) affects the perception of a moving shape (the bicycle), and this influence involves assimilation (averaging) rather than opposition (differentiation). These features distinguish the illusion from illusions of motion capture and induced motion. The authors take this bicycle illusion into the laboratory and report 4 findings: Naïve viewers experience the illusion when discriminating horizontal from sinusoidal motion of a disc in the context of stationary curved lines; the illusion shifts from motion assimilation to motion opposition as the visual size of the display is increased; the assimilation and opposition illusions are dissociated by variations in luminance contrast of the stationary lines and the moving disc; and the illusion does not occur when simply comparing two stationary objects at different locations along the curved lines. The bicycle illusion provides a unique opportunity for studying the interactions between shape and motion perception. </p>
