The Effect of Discrimination Training on Responses to a New Stimulus

Abstract: Most previous research on the effect of the duration of preceding discrimination training on responding to a new stimulus has measured the responding during extinction. To reduce effects originating in the extinction procedure itself, the present study assessed the effect of discrimination training on responses to a new negative stimulus added during continued discrimination training. Pigeons were given a new negative stimulus (blue key) after 0, 1, 3, or 9 days of discrimination training with a yellow key as … Show more

“…Another objective stems from the work with errorless discriminations of pigeons (Terrace, 1963), which indicates remarkable specificity of conditioning effects to particular colors. Terrace (1966) and Anger and Anger (1972) found errorless discrimination for color stimuli without the special techniques of fading-in and gradual lengthening of S-(the stimulus during which pecks are not reinforced). If the effects of both conditioning and extinction can be quite specific to different colors, then changing the key color between each conditioning-extinction pair may make the second conditioning-extinction pair more independent of the first, etc., and thus may reduce the decline in responding between successive extinctions.…”
