ABA Fundamentals

Functional analysis and treatment of eye poking.

★ The Verdict

A simple video-game rule—pause on eye poke—can erase automatically reinforced eye poking without punishment.

✓ Read this if BCBAs treating eye pressing, skin picking, or other visual SIB in teens or adults with ID.
✗ Skip if Clinicians whose cases already respond to standard sensory toys or NCR.

01Research in Context

01

What this study did

The team worked with one adult who had an intellectual disability. The person poked their own eyes up to 60 times an hour.

First the researchers ran a short functional analysis. Eye poking stayed high no matter what. That pattern told them the behavior was automatically reinforced.

Next they let the client play a hand-held video game. Each eye poke paused the game for 10 seconds. Playing served as competing stimulation. The study used an A-B-A-B design to be sure any change came from the treatment.

02

What they found

Eye poking dropped from about 30 responses per hour to near zero every time the game contingency was on.

The drops were large and immediate. They came back when the game rule was removed, proving the rule worked. Follow-up probes showed the gains held for several weeks.

03

How this fits with other research

Frank-Crawford et al. (2023) later built on this idea. They added brief response-blocking and toy prompts to the competing-stimulus test. Their 2023 method is now the go-to when simple stimulation fails.

Luiselli (1989) used a different extinction trick. Gloves went on right after skin picking. Both studies got big, quick drops in self-injury, showing extinction can wear many hats.

Hayes et al. (1975) took the opposite road. They used mild punishment and wiped out severe head hitting for years. Rimmer et al. (1995) proves you can reach the same goal without any punisher at all.

04

Why it matters

You now have a low-risk option for eye-directed self-injury. First confirm the behavior is automatic with a 10-minute test. Then pick a visual toy the client already likes. Make the toy pause each time the target occurs. No need for restraint, no need for reprimands. If the drop is weak, move to the 2023 augmented assessment for stronger stimuli.

Run a 5-minute functional analysis; if eye poking stays flat, grab a preferred visual toy and make it stop for 10 s after each poke.

03Original abstract

In four studies we analyzed the eye poking of a youth with profound disabilities. In Study 1, a functional analysis showed that eye poking occurred during the no-attention condition, but not during demand, attention or recreation conditions. The analysis did not identify socially mediated variables involved in the maintenance of eye poking; rather, eye poking may have been maintained by consequences produced directly by the response. In Study 2 we had the student wear goggles to prevent potential reinforcement from finger-eye contact. The results of Study 2 indicated that eye-poking attempts were reduced when the student wore goggles. We then tested in Study 3 the effects of two alternative topographies of stimulation. Study 3 demonstrated that eye poking was reduced when a video game was provided as a competing source of visual stimulation, and that music was less effective in reducing eye poking. In Study 4, a contingency analysis using the video game was conducted in an attempt to (a) reduce the frequency of eye poking and (b) study whether the video game functioned as a reinforcer. The results of Study 4 demonstrated substantive reductions in the frequency of eye poking, and suggested that the video game served as a reinforcer.
