Transfer and the organization of Perceptual-Motor space

Transfer of adaptation to rotation of the visual field.

“…As found by Pick et al (1972), the results of Experiment I indicate that adaptation transfers from the exposure orientation to other orientations, and that transfer is greatest for an orientation to which S had not been exposed during the distortion.…”

“…Inspection of Figure 3 reveals a pattern of adaptation similar to that found by Pick et al (1972), i.e., primary adaptation (the test lines labeled 90° and 270°) was sometimes greater than generalized adaptation and sometimes less. (Note that in Figures 3, 4, and 5 the abscissa refers to test-line orientation with respect to the manual orientation of the track.)…”

“…Similarly, the present investigation employs a transfer paradigm to investigate the organization of perceptual-motor space. The experiments continue the exploration of a phenomenon reported by Pick, Warren, Mclntyre, and Appel (1972). In Experiment III of that study, 5s were exposed to a 90° rotation of the visual field.…”

Summation of transfer of adaptation gradients

“…Subsequent analyses revealed the pattern of adaptation obtained for the two-dimension exposure condition was similar to that predicted by an algebraic summation of the patterns associated with the one-dimension exposure conditions. These results indicated that the dimensions of perceptual-motor space are not organized as either an integrated system or as an independent set.Research by McIntyre and Pick (1974) and Pick, Warren, McIntyre , and Appel (1972) has been directed toward establishing whether or not perceptual-motor space is an integrated system. Initially, two alternative conceptualizations were considered: Either perceptual-motor space is an integrated system of dimensions in which a modification of one dimension results in the whole system's being modified , or it is a system of independent dimensions in which a modification of one dimension is confined specifically to that dimension.…”
