Multiple‐exemplar training with stimuli in four domains induced two new fill‐based (A19 and A29) and satellite‐image‐based (B19 and B29) perceptual classes. Conditional discriminations were established between the endpoints of the A19 and B19 classes as well as the A29 and B29 classes. The emergence of linked perceptual classes was evaluated by the performances occasioned by nine cross‐class probes that contained fill variants as samples and satellite variants as comparisons, along with nine other cross‐class probes that consisted of satellite variants as samples and fill variants as comparisons. The 18 probes were first presented serially and then concurrently. Class‐consistent responding indicated the emergence of linked perceptual classes. Of the linked perceptual classes, 70% emerged during the initial serial test. An additional 20% of the linked perceptual classes emerged during the subsequently presented concurrent test block. Thus, linked perceptual classes emerged on an immediate or delayed basis. Linked perceptual classes, then, share structural and functional similarities with equivalence classes, generalized equivalence classes, cross‐modal classes, and complex naturally occurring categories, and may clarify processes such as intersensory perception.
