Functional analysis of aberrant behavior maintained by automatic reinforcement: assessments of specific sensory reinforcers.

Patel et al. (2000) · Research in developmental disabilities 2000
★ The Verdict

Match DRO rewards to the exact sensory channel that fuels the behavior—auditory for stereotypy, tactile for SIB.

✓ Read this if BCBAs treating automatically reinforced stereotypy or SIB in older children or adults.
✗ Skip if Clinicians whose clients’ problem behavior is socially reinforced.

01Research in Context

01

What this study did

Logan et al. (2000) tested a new way to find the exact sensory payoff for self-injury and stereotypy. Two males took part. The team first ran a functional analysis to confirm the behaviors ran on automatic reinforcement. Next they let the men sample different sensory items—vibration, music, squeeze balls—while they recorded which items matched the behavior’s sensory channel.

They then built a DRO plan that gave the matched sensory item for time without the problem behavior. Auditory items paid off for stereotypy; tactile items paid off for self-injury. The design was an ABAB reversal so the effect could be seen quickly.

02

What they found

When the DRO reward matched the behavior’s sensory channel, both men’s problem behavior dropped to near zero. When the reward was removed, the behavior returned. When it was reinstated, behavior fell again. Stereotypy was best cut by music; self-injury was best cut by vibration.

03

How this fits with other research

Rooker et al. (2018) reviewed 33 years of automatic-reinforcement SIB studies and found that noncontingent reinforcement works best when items come from a competing-stimulus assessment, not from a simple preference test. Logan et al. (2000) foreshadowed this by matching the DRO item to the exact sensory channel.

Verriden et al. (2025) later compared CSA-selected items with preference items under NCR and showed CSA items won for most kids. Their data extend the 2000 finding: modality match beats general preference.

Virues‐Ortega et al. (2022) offered a short-cut: after any automatic-reinforcement FA, pick the condition with the lowest problem rate and use its sensory item as treatment. This operationalizes the 2000 idea for busy clinics.

Why it matters

You can copy this package in one afternoon. Run a brief alone condition to confirm automatic reinforcement, test a handful of sensory items, then set a DRO timer that delivers the matched item for clean intervals. No need for big preference assessments or dense FCT. If the behavior returns, you know the reward lost its punch—swap in a new modality-matched item. This keeps treatment fresh and avoids escalation.

03Original abstract

The purpose of this study was to develop a systematic functional assessment package for aberrant behaviors maintained by nonsocial (automatic) reinforcement. The assessment package included four components: (1) functional analysis, (2) antecedent assessment of specific automatic reinforcement sources, (3) stimulus preference assessment, and (4) treatment evaluation. Functional analysis data indicated automatic reinforcement functions of the stereotypy exhibited by a 10-year-old male and the self-injury (SIB) exhibited by a 30-year-old male. Antecedent assessments of sensory classes indicated that auditory stimulation and tactile stimulation were associated with stereotypy and SIB, respectively. A multiple-stimulus-without-replacement procedure was conducted with each participant to identify the most- and least-preferred stimuli within the identified sensory classes. In an attempt to validate the assessment package for each participant, a DRO procedure was implemented using a reversal design with a multielement component. DRO procedures using stimuli within the targeted sensory classes were successful in eliminating the aberrant behaviors of both participants. The results are discussed in the context of improving the methodology for assessing and treating automatically reinforced behaviors.
