5/6/2013 5 People report always tracking the ball. But eye data show that we look at the magician’s face before the apex of the ball. Arrows show typical eye movement pattern. On the fake throw, we look at the magician’s face, but not the expected apex of the ball, but nevertheless report seeing the ball disappear there. Dissociation between perception and oculomotor system (not fooled) (recall distinction between what and where/how systems). Eye patterns were same for those who saw the illusion and those that didn’t. First two throws increase expectation of third throw (priming) Sensory Illusions Sensory afterimages and pickpocketing (plus active misdirection of attention with endogenous and exogenous cues and social shared attention) Sleights of mind Thought question Why might a flash of light be used as a device to cover up surreptitious actions?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
