Abstract: | Pigeons’ choices between larger, more delayed and smaller, less delayed reinforcers were examined while the pigeons lived in the experimental chamber for 23-h sessions. In Condition 1, 4 pigeons were food deprived prior to each session and exposed to one session every 4th day. Condition 2 was identical except that the pigeons began each session at their ad-lib weights. Condition 3 was identical to Condition 2 except that sessions were conducted on consecutive days. Condition 4 was identical to Condition 3 except that the subjects (2 pigeons from Conditions 1–3 plus a naive pigeon) could obtain reinforcers much less frequently. In all of the conditions, the pigeons consistently chose the smaller, less delayed reinforcers; the pigeons were impulsive. The restriction of food access caused a disruption in the diurnal pattern of feeding, but did not decrease impulsiveness even in this 23-h live-in procedure. |
