Does increasing absolute conditioned reinforcement rate improve sensitivity to relative conditioned reinforcement...

Area of Science:

• Behavioral psychology
• Operant conditioning

Background:

• Procedural modifications can enhance sensitivity to conditioned reinforcement rates.
• The impact of absolute S+ production rate on this sensitivity remains unevaluated.

Purpose of the Study:

• To investigate how the absolute rate of conditioned reinforcement (S+) production influences sensitivity to relative S+ production rates.
• To assess the effect of varying absolute S+ production rates while keeping relative rates constant.

Main Methods:

• Thirty undergraduate students were randomly assigned to three experimental groups.
• Each group experienced a different absolute S+ production rate, with relative S+ production rates held constant.
• Behavioral sensitivity and the generalized matching equation were analyzed.

Main Results:

• Many participants showed results consistent with prior research on relative reinforcement rates.
• The absolute rate of S+ production did not systematically influence behavioral sensitivity.
• No systematic effect was observed on the quality of fits for the generalized matching equation.

Conclusions:

• Absolute S+ production rate appears to have no significant impact on sensitivity to relative S+ production rates in this context.
• Future research should explore methods for achieving steady-state responding.
• Improving the predictive validity of conditioned stimuli (S+) is a crucial area for future investigation.
