ABA Fundamentals

An analysis of physical guidance as reinforcement for noncompliance.

Kern et al. (2002) · Behavior modification 2002
★ The Verdict

Physical guidance can turn into a prize for saying no when the child just wants your eye contact.

✓ Read this if BCBAs treating noncompliance in clinic or classroom settings.

01Research in Context

01

What this study did

Lee and team looked at physical guidance after kids said no. They asked children with developmental delays to do easy tasks.

When a child did not start, the adult gently moved their hands to finish the task. The team watched if this extra help made future yes or no answers more likely.

02

What they found

The guidance backfired for some kids. If the child wanted adult attention, the hand-over-hand touch gave them exactly that and refusals grew.

For kids who wanted to escape work, the same touch ended the task faster and compliance rose. The same move had opposite effects.

03

How this fits with other research

McConkey et al. (1999) showed guided compliance can beat high-p sequences, but they did not test why it worked. Lee et al. (2002) reveal the hidden reason: the reinforcer behind the refusal decides the outcome.

Boudreau et al. (2015) later proved high-p sequences also flop unless the high-p responses earn real treats, echoing Lee’s warning that weak praise is not enough.

Bullock et al. (2006) went further, showing fixed-time snacks alone can match high-p gains. Together these papers say the same thing: check what the child is really getting before you pick any prompt or guidance.

04

Why it matters

If you skip a quick functional test, your helping hands can become an accidental reward for defiance. Run a 5-minute probe: does noncompliance bring your face closer, or does it stop the demand? Choose guidance only for escape-maintained refusal; use attention extinction plus powerful reinforcers for attention-maintained refusal. This small check saves weeks of accidental practice.

Before you guide a child’s hands, test if compliance rises when you look away after the prompt.

03Original abstract

Physical guidance is a strategy commonly used for noncompliance. In two experiments, we evaluated reinforcing effects of physical guidance. Experiment 1 include three individuals with developmental disabilities who were noncompliant with tasks. Anecdotal observations indicated physical contact was highly reinforcing, and a functional analysis identified attention as a reinforcer for problem behavior. Two conditions compared physical guidance following noncompliance and no physical guidance following noncompliance. Results showed noncompliance increased for all three participants when physical guidance followed noncompliance. The second experiment empirically evaluated the function of noncompliance prior to examining the effect of physical guidance on noncompliance. A functional analysis, conducted with two participants, indicated noncompliance served an escape function for one and an attention function for the other. Comparisons of physical guidance and no physical guidance indicated physical guidance resulted in decreased noncompliance for the participant with an escape function but increased noncompliance for the participant with an attention function.
