Three arbitrary successive matching tasks used for baseline training (left three columns) to test for emergent reflexivity (right column). Sample stimuli are shown to the left of the arrows, and comparison stimuli are shown to the right of the arrows. “+” indicates baseline trials ending in food reinforcement; “−” indicates baseline trials ending without food reinforcement. “(p)” denotes positive (matching) probe trials. “(n)” denotes negative (non-matching) probe trials.
