STIMULUS GENERALIZATION OF THE EFFECTS OF PUNISHMENT.

Three pigeons were trained to respond to seven spectral stimulus values ranging from 490 to 610 mmu and displayed in random order on a response key. After response rates had equalized to these values, a brief electric shock was administered when the subject (S) responded to the central value (550 mmu) while positive reinforcement for all values was maintained. Initially, there was broad generalization of the resulting depression in response rate, but the gradients grew steeper in the course of testing. When punishment was discontinued, the rates to all values recovered, and equal responding to all stimuli was reattained by two of the Ss. Stimulus control over the effects of punishment was clearly demonstrated in the form of a generalization gradient; this probably resulted from the combined effects of generalization of the depression associated with punishment and discrimination between the punished value and neutral stimuli.

Discrimination and generalization on a dimension of stimulus difference.

Four pigeons were trained to peck at one key when two identical stimuli were displayed, and at another key when the stimuli were displayed with a wavelength difference of 40 mmicro. With stimulus combinations ranging in difference from 0 to 70 mmicro in a generalization test, key preference was a function of the degree of difference between the stimuli.

Stimulus generalization of imprinting.

Chicks were imprinted with a bluish object, then tested with different spectral values ranging to yellow-green. A systematic decrement in following was related to the stimulus series, although there was considerable generalization to all test values, which increased during testing. These data lead us to question the "irreversibility" of imprinting.
