Abstract: The present experiment explored the effects of an observing response, or “memory aid,” in a delayed matching-to-sample procedure with pigeons. Trials began with the onset of a sample stimulus (one of two colors on the center key). After a delay (retention interval), two comparison stimuli were presented on side keys, only one of which matched the sample color. Responses on the matching stimulus were reinforced with food. A third (observing) key was made available when the comparison colors were shown, responses on which reproduced the sample color. This effectively converted the delayed matching-to-sample procedure to a simultaneous matching-to-sample procedure. The response requirement on this observing key increased according to a progressive-ratio schedule that began each session at its minimum of 1 response and increased in fixed increments each time the sample stimulus was reproduced. The retention interval was manipulated systematically across conditions to quantify the tradeoff between the costs of remembering and using a memory aid. Accuracy declined with increases in the retention interval. Observing responses rarely occurred spontaneously, but increased in frequency with additional training on simultaneous matching-to-sample trials. The results are discussed in relation to the training histories required to establish observing in a remembering context.
