Duration-based measures of preference for vocational tasks.

We compared results from two preference assessments with data on
extended performance of vocational tasks by 4 participants with
developmental disabilities. All participants engaged in one task
exclusively when seven tasks were available concurrently during a
5-min multiple-stimulus assessment. By contrast, all participants
exhibited high levels of engagement in most tasks when the tasks
were presented singly for 5 min, and these data showed a high
degree of correspondence with those obtained during extended
(60-min) vocational assessments.
