This is the second in a series of experiments designed to examine the possibility of increasing the size of the visual form field by specialized training. The present investigation was concerned with the effect of various amounts of perimetric training on the visual form field. Five groups were used: a control group which received no training, and four groups which received, respectively 10, 20, 30 and 40 half-hour sessions of training. As in a previous experiment, there was considerable improvement in ability to identify familiar stimuli presented farther and farther from the foveal area, but no evidence of transfer to other stimuli.
