When an animal is conditioned to make an operant response to a definitive stimulus is referred to as discrimination training (Gray & Bjorklund, 2014). Herrnstein, Loveland and Cable (1976) argued that comparing the definitive stimuli commonly used in operant conditioning (100 Hz tones, 465 mµ lights) to real natural setting defy concept of responding to a specific stimuli. For example, in natural settings a squirrel will not only respond to acorns similar to the one presented on an image in a controlled lab experiment, the squirrels would respond to all colors and shaped acorns. They generalize the variety of acorns and discriminate other objects within their environment (Herrnstein, Loveland & Cable, 1976). In Herrnstein and others’ discriminative stimuli experiment using variations of stimuli similar to nature, eleven pigeons were put in one of three experimental cages. The pigeons were set on a variable interval schedules with 80 slides being presented. Basically, pigeons were reinforced when they pecks at the images of trees or parts of trees and other random images. If the pigeon pecked at the incorrect image then the latency before the next stimulus was increased. All three experiments were basically the same except the combination of images presented (trees, parts of trees, water and people) Results supports the concept of generalization within images and discrimination (Herrnstein, Loveland & Cable, 1976). The pigeons had ta faster response to the stimulus if it had…
