ABA Fundamentals

Teaching preschool children to avoid poison hazards.

Dancho et al. (2008) · Journal of applied behavior analysis 2008
★ The Verdict

Add one round of in-situ feedback with response interruption after group safety training to lock in poison avoidance for preschoolers.

✓ Read this if BCBAs in preschool or daycare centers who write safety plans for neurotypical children.
✗ Skip if Clinicians working with older youth or self-injury cases where ingestion is function-based.

01Research in Context

01

What this study did

The team ran a safety class for preschoolers. First, all kids got a group lesson on poison hazards. Then the researchers watched who still tried to touch or taste a fake poison bait.

The kids who failed got a second round. An adult stepped in, blocked the reach, and gave quick feedback right on the playground.

02

What they found

Group training alone did not stop most kids. Nearly every child who had passed the lesson still grabbed the bait in the real moment.

After one round of in-situ feedback plus response interruption, almost every child refused the bait. The safe choice lasted weeks later, even with new toys and new rooms.

03

How this fits with other research

Phaneuf et al. (2007) saw the same pattern with moms. Group parent training helped a little, but adding short, personal video clips fixed the problem behavior fast.

Tryggestad et al. (2025) stretched the idea to staff. They paired a 4-hour workshop with 17 weeks of quick coaching and lifted classroom quality. Longer coaching worked for teachers; a single in-situ pass worked for kids.

Chan et al. (2016) used a near-copy recipe: behavioral skills training, real-place practice, and feedback. They taught water safety instead of poison safety and got the same strong gain with neurotypical children.

04

Why it matters

You can toss the old safety coloring sheet. Run a 5-minute group demo, then test for real. The moment a child reaches for the bait, block the hand and say, “Stop, ask an adult.” One correction in the real setting beats ten seat-time lessons. Use the same block-and-feedback loop for hot stoves, stranger approach, or any life-or-death skill.

03Original abstract

We evaluated the effectiveness of group safety training and in situ feedback and response interruption to teach preschool children to avoid consuming potentially hazardous substances. Three children ingested ambiguous substances during a baited baseline assessment condition and continued to ingest these substances following group safety training. In situ feedback and response interruption resulted in a decrease in opening ambiguous containers; this decrease was maintained when ambiguous novel containers were presented and when assessments occurred in a novel setting and with a novel experimenter. For 2 children, these gains were also maintained during a brief follow-up period. Twelve children did not ingest ambiguous substances prior to training, and group safety training did not evoke inappropriate ingestion.
