Performance of humans in concurrent avoidance/positive-reinforcement schedules
Journal of the Experimental Analysis of Behavior
|July 1, 1982
Summary
Human behavior under concurrent schedules shows increased avoidance responding and decreased reinforcement responding as avoided losses increase. Performance aligns with Herrnstein
Area of Science:
- Behavioral psychology
- Operant conditioning
Background:
- Concurrent schedules of reinforcement are fundamental in understanding choice behavior.
- Avoidance and positive reinforcement components interact in complex ways.
Purpose of the Study:
- To investigate human performance under concurrent schedules involving avoidance and positive reinforcement.
- To examine the influence of avoided losses on response allocation.
Main Methods:
- Three human subjects participated in a study using points exchangeable for money.
- Concurrent schedules included variable-interval avoidance and variable-interval positive reinforcement.
- Changeover delays were systematically manipulated (5.0 sec, 2.0 sec, none).
Main Results:
- Response rates in avoidance increased as avoided point-losses increased.
- Response rates in positive reinforcement decreased as avoided point-losses increased.
- Performance generally matched Herrnstein's equations for concurrent schedules, with variations in matching under different changeover delay conditions.
Conclusions:
- Avoidance of losses significantly influences response allocation in concurrent schedules.
- Changeover delay impacts the degree of matching between response rates and reinforcement rates.
- Findings support Herrnstein's quantitative analysis of behavior under concurrent schedules.

Reinforcement Schedules
Positive reinforcement is a powerful method for teaching new behaviors to both animals and humans. B.F. Skinner demonstrated this with his experiments using rats in a Skinner box. When a rat pressed a lever, it received a food pellet. This immediate reward encouraged the rat to repeat the behavior. This method, where a reward follows every instance of the behavior, is known as continuous reinforcement. It is highly effective for establishing new behaviors quickly.

Timing and Consequences on Behavior
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant factor...

Avoidance Learning and Learned Helplessness
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Operant Conditioning Intervention
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.

Social Facilitation
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.
Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the anxiety of...
