Introduction

The principles of operant conditioning, as detailed within behavioral psychology, hinge upon the nuanced understanding of various reinforcement schedules and the mechanisms through which behaviors are learned and sustained. This paper aims to explore two specific reinforcement schedules—fixed-interval and variable-interval—by providing illustrative examples. Additionally, it examines which schedule yields the most effective and resistant behavior, then delves into the concept of shaping through successive approximations, providing a detailed example to illustrate this process.

Fixed-Interval and Variable-Interval Schedules

A fixed-interval (FI) schedule involves providing reinforcement following a constant, predetermined amount of time, provided that the desired behavior occurs at least once after the interval elapses. An example of an FI schedule is a weekly paycheck in a workplace where employees receive their salary every Friday regardless of their performance during the week. In this case, the reinforcement (salary) is contingent on the passage of a fixed time, and the behavior of working is reinforced only after the specified interval.

Conversely, a variable-interval (VI) schedule involves reinforcement after unpredictable amounts of time that fluctuate around a certain average. An example of a VI schedule would be an employee receiving an email response from a supervisor, but the response time varies unpredictably from a few minutes to several hours. The reinforcement (email response) occurs after an unpredictable time interval, which maintains a steady rate of responding because the individual cannot predict exactly when the reinforcement will occur.

Comparison of Schedules: Response Rate and Resistance to Extinction

When evaluating which schedule yields the best response and maintains behavior most resistant to extinction, research indicates that variable schedules, particularly variable-ratio (VR), are most effective (Lucke, 2020). However, among interval schedules, the variable-interval schedule generally produces a steadier and more persistent response compared to the fixed-interval schedule, whose pattern often shows a “scalloped” response curve—where responses are concentrated just before reinforcement (Miller, 2019).

The reason for the heightened resistance to extinction in variable schedules lies in their unpredictability; subjects learn that reinforcement is unpredictable, which enhances persistence. A VR schedule, for example, tends to produce high response rates because the subject perceives that reinforcement is available after an unpredictable number of responses, leading to greater resistance to extinction as the subject continues behavior in hope of reinforcement, even after reinforcement ceases.

Shaping by Successive Approximations

Shaping by successive approximations refers to a behavioral modification process where complex behaviors are gradually learned through reinforcing closer and closer versions of the target behavior. This method involves reinforcing behaviors that approximate the desired response initially, then reinforcing behaviors that are increasingly similar to the final behavior, until the complete response is achieved (Bobrow & Pickens, 2021).

A practical example of shaping is training a dog to roll over. Initially, the trainer rewards the dog for lying down (first approximation). Once the dog reliably performs lying down, the trainer then rewards the dog for turning its head in the rolling direction (second approximation). Subsequently, the trainer reinforces a partial roll, then a full rollover, each step reinforcing behaviors that progressively resemble the final goal.

The step-by-step process involves:

1. Identifying the final targeted behavior (full rollover).

2. Breaking the behavior into manageable, teachable steps (lying down, turning the head, partial roll, full roll).

3. Reinforcing each successive behavior that remotely resembles the final response.

4. Gradually increasing the criterion for reinforcement until the complete behavior is performed consistently.

This method utilizes principles of operant conditioning where reinforcement is contingent upon behavior approximating the final desired response, facilitating learning of complex behaviors that might not be acquired through direct teaching alone.

Conclusion

In sum, understanding reinforcement schedules and the process of shaping provides powerful tools in behavioral modification. Variable schedules, especially the variable-ratio schedule, tend to produce more persistent and resistant behaviors as they introduce unpredictability, which sustains response rates and resilience against extinction. Shaping, through successive approximations, enables the gradual acquisition of complex behaviors by reinforcing behaviors that incrementally approach the ultimate goal, exemplifying the practical application of operant conditioning principles.
