REINFORCEMENT VARIABLES IN THE CONTROL OF UNIT READING RESPONSES.

Area of Science:

• Behavioral Psychology
• Child Development
• Learning Sciences

Background:

• Understanding how reinforcement schedules influence behavior is crucial in developmental psychology.
• Previous research indicates varied effects of different schedules on learning and response rates.

Purpose of the Study:

• To investigate the impact of four distinct multiple schedules of reinforcement on the rate of verbal responding in children.
• To compare response rates across Continuous Reinforcement (CRF), Variable Ratio (VR), Variable Interval (VI), and Extinction (EXT) components.

Main Methods:

• Employed four multiple schedules: multiple CRF-EXT, multiple CRF-VR, multiple CRF-VI, and multiple VR-VI.
• Each schedule was applied to a single child participant.
• Quantified the rate of verbal responding to written material under each schedule component.

Main Results:

• Response rates were highest under Variable Ratio (VR) schedules and lowest under Extinction (EXT).
• Rates under Continuous Reinforcement (CRF) were lower than VR but higher than Variable Interval (VI).
• The multiple VR-VI schedule showed minimal rate differences between its VR and VI components.

Conclusions:

• Variable Ratio reinforcement schedules are highly effective in increasing verbal response rates in children compared to other schedules.
• The interplay between different schedules, particularly VR and VI, warrants further investigation regarding response rate consistency.
