Document Summary
Prisms are lenses that displace the visual world laterally. Reaching for objects while wearing prisms leads to error because objects are not where they appear to be. There is also a discrepancy between visual and proprioceptive information (the sense of position) in that we see our hand in one place yet feel it in another. This laboratory exercise demonstrates the phenomenon of adaptation. Materials: prisms mounted in goggles with one eye occluded. Prisms are base right or base left and displace light by 11 degrees. The displacement is away from the base of the prism: wooden pointing boxes. Two ends are open - one end is curved, the other is straight. The curved end contains small holes at equal radial intervals: golf pencil targets, pointers. Students will work in pairs, one as subject the other as experimenter. After running the entire procedure, switch roles and run it again.
