Abstract
Following initial discrimination training between two wavelength stimuli and a subsequent generalization test to the wavelength dimension, Group 1 was “overtrained” for 105 days on the original discrimination. Group 2 was “overtrained” with the original positive stimulus and a new negative stimulus, a white line. Group 3 was “overtrained” with the original negative stimulus and a new positive stimulus, the white line. Each 15 days of extended training were followed by a wavelength generalization test similar to the first test. The results suggest that there is no consistent relationship between the response rate in positive stimulus immediately before the generalization test and whether or not a peak shift occurs during the test.
