Multiple-exemplar training with stimuli in four domains induced two new fill-based (A1' and A2') and satellite-image-based (B1' and B2') perceptual classes. Conditional discriminations were established between the endpoints of the A1' and B1' classes as well as the A2' and B2' 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 fuctional similarities with equivalence classes, generalized equivalence classes, cross-modal classes, and complex maturally occurring categories, and may clarify processes such as intersensory perception.
对四个领域的刺激进行多范例训练诱导出了两个新的基于填充的（A1'和A2'）以及基于卫星图像的（B1'和B2'）知觉类别。在A1'和B1'类别以及A2'和B2'类别的端点之间建立了条件辨别。通过九个交叉类别探测来评估关联知觉类别的出现，这九个探测包含填充变体作为样本以及卫星变体作为比较项，还有另外九个交叉类别探测，由卫星变体作为样本以及填充变体作为比较项组成。这18个探测首先依次呈现，然后同时呈现。类别一致的反应表明了关联知觉类别的出现。在关联知觉类别中，70%在最初的依次测试中出现。另外20%的关联知觉类别在随后呈现的同时测试块中出现。因此，关联知觉类别在即时或延迟的基础上出现。那么，关联知觉类别与等价类别、广义等价类别、跨模态类别以及复杂的自然出现的类别在结构和功能上具有相似性，并且可能阐明诸如跨感觉通道知觉等过程。
