ABA Fundamentals

An evaluation of factors that influence children's instruction following.

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

Kids with ID follow directions better when only task objects are in view and each set links to one command.

✓ Read this if BCBAs running tabletop or classroom programs for children with intellectual disability.
✗ Skip if Clinicians who only treat verbal adults or home-based parent coaching without object tasks.

01Research in Context

01

What this study did

Ellingsen et al. (2014) watched kids with intellectual disability during tabletop tasks.

They moved toys on and off the table to see what made the kids follow adult directions.

Each child got the same instruction, but the objects in sight changed every few trials.

02

What they found

Kids followed directions best when only the needed items were on the table.

When many toys were present, or when one set of toys went with two different instructions, compliance dropped.

The setup of stuff, not the instruction itself, drove most of the yes-or-no answers.

03

How this fits with other research

Wilder et al. (2020) later added prizes to the same three-step prompt package and got better results. Their upgrade shows that when objects alone are not enough, pairing the first prompt with a reinforcer can close the gap.

Planer et al. (2018) also boosted compliance by picking high-probability tasks and mixing the order. Both papers echo R et al.: change what happens before the instruction and you change the child’s response.

Harrington et al. (2006) saw the highest preschool compliance when teachers used quick, embedded “do” requests. That natural-room result lines up with R et al.’s lab finding: fewer distractions and clearer cues make kids say “okay” more often.

04

Why it matters

Clear the table before you give a direction. Leave out only the materials that go with that one task. If the child still hesitates, add a quick reinforcer like Wilder et al. (2020) or a high-p warm-up like Planer et al. (2018). This simple room reset costs nothing and can cut repeated prompts in half.

03Original abstract

Behavior that resembles instruction following might sometimes be under stimulus control of extraneous variables. We evaluated the effects of some of these variables (i.e., presence of relevant objects, associations between instructions and object sets) with 3 children with intellectual disabilities. In Experiment 1, we assessed whether subjects were more likely to follow instructions that required object manipulation and whether subjects were more likely to follow these instructions when only relevant objects were present. All subjects were more likely to follow instructions that required object manipulation when only relevant objects were present. In Experiment 2, we evaluated whether instruction following would be less likely if the same object set was associated with multiple instructions, and found this to be the case for 2 of 2 subjects. Findings highlight the need to train instruction following under different conditions to ensure that responding comes under stimulus control of the instructions.
