Conditioned reinforcement dynamics in three-link chained schedules
Article Abstract:
The effects of stimuli in a chain schedule are due to the time to food correlated with the stimuli and to the time to the next conditioned reinforcer in the sequence. Rats prefer the chain with the additional terminal-link presentations in the presence of food, and in its absence, the outcome depends upon the nature of the stimuli associated with these links. Preference is against choice alternative in case of stimuli different from the reinforced baseline terminal links, and is near indifference in case of same stimuli.

Effects of reinforcement schedule on facilitation of operant extinction by chlordiazepoxide
Article Abstract:
Male C57BI/6 mice, were trained to lever press on discrete-trial fixed-ratio 5 or fixed-interval schedules of food reinforcement and then exposed to 15 extinction session following vehicle or chlordiazepoxide injections, administered prior to all extinction sessions, or prior to the final 10 extinction sessions. Resistance to extinction was equally high, following training with either schedule type and was reduced by drug administration in both the cases.

Comparing locomotion with lever-press travel in an operant simulation of foraging
Article Abstract:
Experimentation with laboratory conditions that modeled various rat foraging environments indicated that operant techniques can be used for studying foraging behavior. Results support the use of lever-press travel to model rat movement between foraging patches although this technique may not be appropriate for movements that expend more energy. Data contradict some optimal foraging models but support a model of optimal giving-up time in foraging.
