title: Parametric effects of reinforcement frequency, amount of reinforcement, and required response force on sheltered workshop behavior.
abstract: Three experiments involving parametric manipulation of reinforcement contingencies were performed with retardates in an automated Sheltered Workshop token economy. Experiment I showed that with amount of reinforcement held constant, work rates were positively related to reinforcement rates on fixed-interval schedules and inversely related to reinforcement rates on fixed-ratio schedules. Experiment II demonstrated an interaction between frequency of ratio reinforcement and torque required to complete a work unit: work rates were positively related to reinforcement rates when required response force was high and negatively related to reinforcement rates when required response force was low. Experiment III revealed that, with reinforcement frequency held constant, there was in inverse relationship between amount of reinforcement and work rate.
