Water Presentation

Two dogs were trained to perform a left-right discrimination task in which depressing a treadle presented a compound visual and auditory stimulus in random order appropriate to one or the other of two distant reinforcement stations. Depression of the appropriate discrimination treadle was reinforced by water presentation. A modified correction procedure was used in training. Following acquisition, probe test trials consisting of the visual stimulus component alone, the auditory stimulus component alone, and reversed or cues-opposed compound stimulus were presented. Test trials demonstrated the visual component of the compound stimulus to have acquired discriminative control, but the cues-opposed test trials also demonstrated a low but extant degree of discriminative control exerted by the auditory stimulus component. As the compound stimulus employed here consisted of visual components differing only in location and auditory components differing only in pitch, implications for future research manipulating further these qualitative and quantitative variables were discussed.

Per Se

Six rats were exposed to schedules of free-operant shock avoidance. For three of these, auditory or visual stimuli were present continuously throughout each experimental session. For the remaining three rats, these stimuli were presented only 5 sec. before an avoidable shock, and were removed by any operant response to be emitted during their presence. For these latter rats, the stimuli developed strong discriminative control over the emission of operant responses. When the avoidance behaviour had stabilized, the effects were studied of a stimulus which preceded an unavoidable shock of the same intensity as that maintaining the avoidance responding. These effects were studied in the following conditions: against the ongoing avoidance behaviour; with no avoidance stimuli present; and against extinction of avoidance behaviour. With the animals exposed to continuous schedule stimuli, all these experimental conditions resulted in an acceleration of responding during the signal which preceded an unavoidable shock. The rats with the strong stimulus control of avoidance responding afforded by the discontinuous schedule stimuli never showed such an acceleration; indeed all three animals showed suppression of their operant responding in the final experimental condition. It therefore appears that experience of shock avoidance per se is not sufficient to produce the acceleration effect: the discriminative control of behaviour, or lack of it, is also implicated.
