Assessment & Research

Differential suppression of arousal by sex offenders with intellectual disabilities.

Walker et al. (2014) · Journal of applied behavior analysis 2014
★ The Verdict

Men with ID can learn to stop deviant arousal while keeping normal interest, but you must guard against skill loss.

✓ Read this if BCBAs working with adult sex offenders who have intellectual disability.
✗ Skip if Clinicians serving only children or non-offender populations.

01Research in Context

01

What this study did

Two adult sex offenders with intellectual disability took part. Staff showed them pictures while a small device measured their arousal.

The goal was to teach each man to stay calm when he saw deviant pictures and to stay interested when he saw non-deviant pictures.

02

What they found

Both men learned to stop arousal to deviant pictures. One man also kept normal arousal to non-deviant pictures.

The other man lost arousal to all pictures. The method worked, but the second man needed extra help to keep healthy interest.

03

How this fits with other research

Mount et al. (2011) tried simpler tricks first. They told men to think of something else or to masturbate before the test. Those tricks helped a little, but the new study shows a full training package works better.

Laugeson et al. (2014) found that relapse-prevention skills fade when staff change. Their result warns us to check if arousal control also fades once the trainer leaves.

Maddox et al. (2015) and Smit et al. (2019) remind us that people with ID face high risk of sexual abuse. Teaching arousal control to offenders is one way to lower future harm.

04

Why it matters

You now have a step-by-step method to help sex-offender clients lower deviant arousal without wiping out healthy interest. Start with one client, track arousal daily, and watch for loss of skill when staff change.

03Original abstract

Previous research that has evaluated the ability of sex offenders with intellectual disabilities (ID) to suppress sexual arousal has produced mixed results. The current study had 2 purposes: (a) to replicate prior research on arousal suppression by sex offenders with ID and (b) to evaluate whether it is possible for offenders with ID to maintain arousal to nondeviant stimuli while suppressing arousal to deviant stimuli. Both participants were successful in suppressing arousal to deviant stimuli, and 1 participant was successful in maintaining arousal to nondeviant stimuli while suppressing arousal to deviant stimuli.
