Herrnstein and Heyman

Area of Science:

Behavioral psychology
Animal behavior studies

Background:

Herrnstein and Heyman (1979) proposed matching law in concurrent schedules.
Observed behavior ratios matched reinforcer frequencies, not maximizing rates.

Purpose of the Study:

Investigate if choice allocation influences reinforcer frequencies.
Re-examine the primacy of matching over maximizing behavior.

Main Methods:

Computer simulations of behavior ratios on concurrent schedules.
Algebraic determination of reinforcement rates using reinforcement-feedback functions.
Experimental manipulation of choice ratios in pigeons using concurrent variable-interval variable-ratio schedules.

Main Results:

Simulated matching occurred across experimenter-specified choice ratios.

Related Experiment Videos

Matching also observed at arbitrary ratios when reinforcement rates were algebraically determined.

Experimental results showed matching between choice and reinforcer-frequency ratios.

Conclusions:

Reinforcer frequencies appear to track choice allocation, challenging previous interpretations.
The 'matching-as-outcome' may not solely result from 'matching-as-process'.
