Effects of chosen versus assigned jobs on the work performance of persons with severe handicaps.
Letting adults with severe ID pick their work task doubles on-task time.
01Research in Context
What this study did
Parsons et al. (1990) asked adults with severe intellectual disability to do three kinds of work sessions.
In one session each person picked the job. In another the supervisor gave them a job they liked. In the third the supervisor gave them a job they did not like.
Staff watched and timed how long each adult stayed on task.
What they found
When people chose the job or were given a liked job, they worked almost twice as long.
Non-preferred jobs cut work time in half.
A simple choice doubled engagement.
How this fits with other research
Eberhart et al. (2006) later showed the same boost works at home. Three adults in supported living tripled their leisure time when staff offered a quick choice and light prompt.
The 2006 study extends the 1990 finding from the workshop to the living room and adds a small prompt.
Ford et al. (2022) looked at choice too, but with older adults who have neurocognitive disorder. They found single-stimulus preference tests predict engagement better than rank-order lists.
All three papers say the same thing in different places: let the person pick, and they will stay engaged longer.
Why it matters
If you run a day program or sheltered workshop, build in a one-minute choice period before each task. Ask "Which job today?" and honor the answer. You will see longer work bursts and less staff prompting. No extra cost, big payoff.

03Original abstract
We evaluated the effects of several choice-related variables on the work performance of adults with severe handicaps. After assessing client work preferences, three choice-related situations were presented: (a) providing clients with the opportunity to choose a work task, (b) assigning a preferred task, and (c) assigning a nonpreferred task. Results indicated that clients attended to work tasks almost twice as much when they chose their tasks and when assigned to work on preferred tasks versus when assigned to work on nonpreferred tasks. Results are discussed regarding the need to assess systematically the effects of choice-related variables.
