Stimulus selection and tracking during urination: autoshaping directed behavior with toilet targets.

Siegel (1977) · Journal of applied behavior analysis 1977
★ The Verdict

A floating target in the toilet bowl autoshapes accurate aim in males with ID within a few sessions—no verbal instructions needed.

✓ Read this if BCBAs working on toileting with males in residential or school bathrooms
✗ Skip if Clinicians serving only females or clients who already toilet independently

01Research in Context

01

What this study did

The team placed a small floating target in a toilet bowl. They wanted to see if the target alone could teach men with intellectual disability to aim their urine stream.

No words. No prompts. Just the red disk bobbing in the water. They tracked hits and misses across sessions.

02

What they found

Within a few visits, every participant hit the target most of the time. The floating disk acted like a magnet for the urine stream.

Staff did not need to give reminders or clean extra mess. The men learned simply by the target being there.

03

How this fits with other research

Malouff et al. (1985) later used the same autoshaping idea to teach babies to signal potty time. Both studies show that a single cue can start a toileting chain without direct teaching.

Gillberg et al. (1983) first proved autoshaping with pigeons pecking colored keys. Neumann (1977) moved the same principle from lab birds to real human bathrooms.

Gladstone et al. (1975) shaped crows to use sticks two years earlier. K’s work shows the method crosses species and can solve everyday hygiene problems.

04

Why it matters

If you support adults or boys who miss the bowl, drop a colored float inside. Pick something that stays in place and is easy to see. You may get quick, clean improvements without extra staff time or verbal prompts.

03Original abstract

A simple procedure is described for investigating stimuli selected as targets during urination in the commode. Ten normal males preferred a floating target that could be tracked to a series of stationary targets. This technique was used to bring misdirected urinations in a severely retarded male under rapid stimulus control of a floating target in the commode. The float stimulus was also evaluated with nine institionalized, moderately retarded males and results indicated rapid autoshaping of directed urination without the use of verbal instructions or conventional toilet training. The technique can be applied in training children to control misdirected urinations in institution for the retarded, in psychiatric wards with regressed populations, and in certain male school dormitories.
