Assessing object-to-picture and picture-to-object matching as prerequisite skills for pictorial preference assessments.
Journal of Applied Behavior Analysis,
38, 543-547.
Tangible and pictorial paired-stimulus (PPS) preference assessments were
compared for 6 individuals with developmental disabilities. During tangible
and PPS assessments, two edible items or photographs were presented
on each trial, respectively, and approach responses were recorded.
Both assessments yielded similar preference hierarchies for 3 participants
who could match pictures and objects but different hierarchies for 3
participants who could not. Reinforcer assessments verified that items
identified as high preference on PPS assessments functioned as
reinforcers only for participants with matching skills.
