ABA Fundamentals

An evaluation of labeling-then-doing with moderately handicapped persons: acquisition and generalization with complex tasks.

★ The Verdict

Have students say the step aloud right before doing it—this simple 'label-then-do' sequence boosts generalization of computer and money tasks.

✓ Read this if BCBAs teaching vocational or daily-living skills to teens or adults with intellectual disability.
✗ Skip if Practitioners working with non-verbal clients or very young children.

01Research in Context

01

What this study did

Researchers taught young adults with intellectual disability two real-life tasks: typing numbers into a computer and writing checks. Before each step, the learner said the step out loud, then did it. This 'label-then-do' method was tested in a multiple-baseline design across participants.

02

What they found

Every learner mastered both tasks. They kept using the spoken labels on their own. The skills and the labels transferred to new settings and similar tasks without extra teaching.

03

How this fits with other research

Volkmar et al. (1985) had already shown that picture prompts alone can teach computer steps. P et al. added the self-spoken label and still got strong generalization, so the label seems to boost transfer beyond pictures.

Charlop et al. (1990) taught the same checkbook skill with a self-paced workbook instead of spoken labels. Both studies saw wide generalization, giving you two proven paths for money skills.

Gianoumis et al. (2012) reviewed 54 caregiver-training studies and flagged 'mediated generalization'—where the learner uses self-speech or self-cues—as a top tactic. The 1988 paper is a clear example of that tactic working.

04

Why it matters

If a client can talk, have them state the step right before they do it. The tiny pause embeds a self-prompt that travels with them to new places. You can add this label to any task list or picture strip you already use.

03Original abstract

We conducted two experiments in which moderately mentally retarded persons were trained first to label and then to enter characters into a computer, calculator, or checkbook (label-then-do) within a multiple baseline design. In Experiment 1, 5 young adults were trained to enter statistical programs into computers in an office setting. Following training, all subjects' use of verbal labels and key-entry skills generalized across tasks (programs) and settings (offices and computer terminals). In Experiment 2, 3 junior high school students were trained with self-labeling procedures to complete a key-entry task and to balance a checkbook. The performance of all students generalized across tasks and settings, and the use of labels generalized for 2 of the students. Results are discussed relative to mediated generalization and to establishing verbal control over behavior.
