Evaluation of a vocal mand assessment and vocal mand training procedures.
A five-minute vocal mand test shows which teaching tactic will unlock a child’s first spoken request.
01Research in Context
What this study did
Bourret et al. (2004) worked with three children who had autism or developmental delays. None of the kids could ask for things with spoken words.
First the team ran a quick vocal mand assessment. They tested if prompting, extra reinforcement, or shaping worked best for each child. Then they used the winning tactic to teach each kid to ask for favorite toys or snacks.
What they found
Every child learned to ask for what they wanted out loud. The assessment picked the right teaching method each time.
Kids started using the new words during normal class time, not just at the table.
How this fits with other research
Rosenthal et al. (1980) showed that you must teach the request under the real cue you want the child to use later. Jason et al. add a pre-test so you know which teaching tactic to pick first.
Ringdahl et al. (2023) found that lots of prompts do not always make manding last longer. Jason et al. agree; their quick assessment helps you choose the least prompt the child actually needs.
Carnett et al. (2016) later used the same assess-then-train idea to teach kids to ask questions with an iPad. The logic works for speech or devices.
Frampton et al. (2024) tutorial tells you to watch for pointing or gaze before you prompt. Jason et al. did not look at those early signs, so you can blend both tips: note the child’s reach, then run the vocal mand test.
Why it matters
You can copy the five-minute vocal mand assessment in any clinic or classroom. Test prompting, extra reinforcers, and shaping once. Pick the tactic that gives the first clear word. You will waste fewer sessions on the wrong prompt level and see faster spontaneous requests.

03Original abstract
A common deficiency in the verbal repertoires of individuals with autism and related disorders is the absence of socially appropriate vocal mands. The vocal mand repertoires of these individuals may be lacking in several respects: (a) The individual might engage in no mands whatsoever, (b) the mand might be topographically dissimilar to an appropriate response, (c) the mand might be only partially topographically similar to an appropriate response, and (d) the mand might occur only after prompting. Depending on specific deficiencies in an individual's repertoire, different procedures for establishing appropriate mands may be needed. The purpose of Study 1 was to evaluate an assessment prior to teaching vocal mands for 3 individuals with developmental disabilities. The assessment showed that 1 individual displayed partial utterances of mands, 1 displayed vocal mands after mands had been reinforced, and 1 displayed vocal mands when prompted. Thus, in Study 2, a different teaching strategy was tested for each individual. Results showed that the assessment information could be linked directly to mand training for all 3 participants.
