Effects of a signaled delay to reinforcement in the previous and upcoming ratios on between-ratio pausing in fixed-ratio schedules
(Society for the Experimental Analysis of Behavior, 2012)Domestic hens responded under multiple fixed-ratio fixed-ratio schedules with equal fixed ratios. One component provided immediate reinforcement and the other provided reinforcement after a delay, signaled by the offset ... -
The effects of delay-to-reinforcement, response requirement and schedule duration on performance under fixed-ratio schedules
(University of Waikato, 2011)Experiment 1 examined the effects of delay-to-reinforcement on between-ratio pausing in multiple fixed-ratio 5 fixed-ratio 5 schedules. In one component the reinforcer was delivered immediately on completion of the ratio, ... -
The relation between preference and demand for litter substrates in the domestic hen
(The University of Waikato, 2006)Six hen's preferences between 5-min access to each of two litter substrates, sand and sawdust, were measured using dependent concurrent VI 60 s VI 60 s schedules of reinforcement. The obtained preferences were small and ...
