The effects of providing access to stimuli following choice
making during vocal preference assessments.
Journal of Applied Behavior Analysis,
39, 501-506.
Two variations of a vocal paired-stimulus preference assessment were
evaluated to determine whether the verbal reports of preference, given
by individuals with developmental disabilities when no access to the
activity was given, matched their verbal reports when access to the
activity was given contingent on their choice. The results indicated
different outcomes between the two methods for 6 of the 7 participants.
Subsequent reinforcer assessments, conducted for 2 participants, showed
that activities identified in the preference assessments that provided
access contingent on selection resulted in more responding than did
activities identified in the preference assessment that did not include
access to items following their selection.
