Figure 4.

Percent of trials the high preference objects (dark bar) and pictures (light bar) were selected during the interspersed object and picture preference assessments at baseline (BL), after training each task, and at follow-up. Participants 1 and 2 showed improved concordance between preference assessments using objects and pictures of the same objects after mastering two and three training tasks, respectively. Participant 3 did not show concordance between object and picture preference assessments after mastering two tasks.
