2 Reinforcement for Skill Acquisition

How reinforcement supports skills

Reinforcement supports skill development when a consequence follows a response and makes that response more likely in the future. It can help build skills such as asking for help, completing a task, or following a direction. A consequence is not necessarily a reinforcer just because it is offered or enjoyed; its effect on the response must be evaluated.

Selecting effective reinforcers

People differ in what they value, and preferences can change with time, context, and access. Learn about the learner’s interests, offer meaningful choices, and observe what the learner selects, approaches, and engages with.

A Preference assessment can help identify promising options by offering items in pairs or in an array. However, a preference assessment does not show by itself that an option will strengthen the skill being taught. A Reinforcer assessment checks whether access to the option actually increases the target response.

Whenever possible, choose options that are age-appropriate, safe, culturally responsive, and practical in the teaching environment. Social interaction, activities, breaks, and access to materials may be included when they are genuinely preferred; do not assume praise is reinforcing for everyone. Respect communication, choice, and signs that the learner wants to stop or change an activity. Essential needs and basic rights should never depend on completing instructional demands.

For example, when a learner is practicing requesting a marker, an instructor can offer a choice of marker colors and observe the selection. If access to the chosen marker after an independent request leads to more independent requests, that access is functioning as a reinforcer in that situation.

Delivering reinforcement effectively

For a newly taught response, deliver the selected consequence promptly and reliably after the defined target response. Make the connection clear—for example, “You asked for help—here it is.” Keep the consequence appropriate in amount and duration, and allow the learner to choose when feasible. A short delay, inconsistent delivery, or a consequence the learner no longer wants may weaken its effect.

During skill acquisition, instructors often reinforce each correct response. They may arrange more valuable or preferred consequences for independent responses than for prompted responses to encourage independence. This approach depends on fading prompts, while still providing supportive feedback for prompted attempts.

The effects of reinforcer type and delivery vary across learners and studies. Monitor the learner’s actual progress rather than relying on one preferred item or a general rule.

Choosing a reinforcement schedule

A reinforcement schedule specifies which responses, or how much time, must pass before reinforcement is delivered.

• Continuous reinforcement (FR 1): Reinforce every correct target response. This is commonly used when establishing a new skill so each response contacts its consequence.

• Intermittent reinforcement: Reinforce only some target responses. Once a skill is reliable, reinforcement can be thinned gradually so the skill continues when reinforcement is less frequent.

• Ratio schedules: Reinforcement depends on the number of responses. A fixed-ratio schedule requires a set number; a variable-ratio schedule requires a changing number that averages around a planned value.

• Interval schedules: Reinforcement depends on time. A fixed-interval schedule makes reinforcement available after a set period; a variable-interval schedule varies the period.

For example, a learner might initially receive reinforcement after every independently completed step. Once the steps become reliable, the instructor could reinforce after a short sequence of steps and then gradually increase the sequence. Change the schedule in small, data-informed increments; if performance drops, make reinforcement more available again. Continuous reinforcement is often used to teach skills, with intermittent schedules introduced for maintenance, but the appropriate arrangement depends on the learner and task.

Evaluating effectiveness and adjusting

Evaluate outcomes rather than assumptions. Record measures suited to the skill, such as independent correct responses, accuracy, response rate, or time to complete a task. Compare performance across sessions and note whether the learner engages with the consequence, requests it, or appears to prefer another option. A preference assessment can help generate choices; a direct reinforcer assessment tests whether a consequence strengthens responding.

If progress slows or engagement changes, check that the target response is clearly defined, reinforcement is delivered as planned, and prompts or task difficulty are appropriate. Then reassess preferences or compare a small number of safe, acceptable options. When practical, change one feature at a time—for example, the reinforcer, its timing, or the schedule—so the effect is easier to interpret. Preferences and effectiveness depend on context, so review them regularly.

Select reinforcers based on current preferences, then verify their effect by measuring behavior. Use frequent reinforcement while establishing a skill and thin schedules gradually as the skill becomes reliable. Continue monitoring progress, engagement, choice, and assent; revise the plan when the evidence shows it is not working.
