ABA Fundamentals

Covariation between bizarre and nonbizarre speech as a function of the content of verbal attention.

DeLeon et al. (2003) · Journal of applied behavior analysis 2003
★ The Verdict

The words you speak while giving attention can turn bizarre speech up or down.

✓ Read this if BCBAs testing functional analyses of unusual vocal behavior in day or residential programs.
✗ Skip if Clinicians working only with physical aggression or with very young verbal children.

01Research in Context

01

What this study did

The team ran a functional analysis on bizarre speech in adults with developmental delay.

They tested whether the words the therapist said changed the client’s odd statements.

Attention was given either about the bizarre talk or about normal talk, then they counted what happened.

02

What they found

Bizarre speech jumped when the therapist spoke about the bizarre content.

The same speech dropped when the therapist spoke about everyday topics.

The form of attention, not just its presence, controlled the behavior.

03

How this fits with other research

Duker et al. (1991) already showed that steady attention or teaching new phrases can erase bizarre speech.

DeLeon et al. (2003) adds a twist: the words you use while giving that attention still matter.

Taylor et al. (1993) found problem behavior only when the adult talked to another adult, proving attention details count.

Repp et al. (1992) split kids into attention-seeking and social-avoiding groups, again showing attention is not one-size-fits-all.

04

Why it matters

During your next functional analysis, script what you will say before you say it.

If the client’s odd talk grows when you comment on it, switch your comments to ordinary topics and watch it shrink.

This tiny change costs nothing and can speed up treatment.

03Original abstract

A functional analysis suggested that the bizarre speech of an individual with developmental disabilities was maintained by attention. The content of verbal attention was manipulated in two subsequent analyses and revealed that (a) bizarre speech was more frequent when attention was related to the participant's bizarre speech and (b) the participant's statements tended to reflect the content of the therapist's attention, whether bizarre or nonbizarre.
