Ambiguous Quartet

This page shows a classic perceptual rivalry stimulus, the dot quartet. Also you can try some adaptation on yourself, by staring at the biased quartet for a bit and then flipping over to the ambiguous quartet. Have a look. (I made this so people could understand our paper on tactile rivalry, which essentially delivered these dots in tactile form to your finger tip.) [paper] [press release]

Massive Memory

We showed people thousands of pictures of objects, one at a time, for three seconds each, and afterwards we asked what people could remember about the images they viewed. It turns out people can distinguish which object they saw when presented with two very similar objects, demonstrating people can remember many object details about thousands of objects. If you're not convinced, try out the demo! Also, you can download the stimuli used in the experiment at this webpage. [paper] [press release]

Crossmodal Motion Aftereffects

Are there shared representations between visual and tactile motion? To test this question we used an adaptation paradigm. Adapting to visual motion upward will cause a subsequently presented static stimulus to look as if it's moving downard. Suprisingly, we find that this motion illusion transfers between vision and touch: adapting to visual motion can lead to a tactile motion illusion across your finger; adapting to tactile motion sweeps can lead to a visual motion illusion as well!
