When the stimuli in one perceptual class (A') become related to the stimuli in another perceptual class (B'), the two are functioning as a single "linked perceptual class". A common linked perceptual class would be the sounds of a person's voice (class A') and the pictures of that person (class B'). Such classes are ubiquitous in real world settings. We describe the effects of a variety of training procedures on the formation of these classes. The results could account for the development of naturally occurring linked perceptual classes. Two perceptual classes (A' and B') were formed in Experiment 1. The endpoints of the A' class were called anchor (Aa) and boundary (Ab) stimuli. Likewise, the anchor and boundary stimuli in the B' class were represented as Ba and Bb. In Experiment 2, the A' and B' classes were linked by the establishment of one of four cross-class conditional discriminations: Aa[right arrow]Ba, Aa[right arrow]Bb, Ab[right arrow]Ba, or Ab[right arrow]Bb. Results were greatest after Aa[right arrow]Bb training, intermediate after Aa[right arrow]Ba and Ab[right arrow]Ba training, and lowest after Ab[right arrow]Bb training. Class formation was influenced by the interaction of the anchor/boundary values and the sample/comparison functions of the stimuli used in training. Experiment 3 determined whether class formation was influenced by different sets of two cross-class conditional discriminations: Aa[right arrow]Ba and Ab[right arrow]Bb, or Aa[right arrow]Bb and Ab[right arrow]Ba. Both conditions produced equivalent results. Similarities were attributable to the use of anchor stimuli as samples and boundary stimuli as comparisons in each training condition. Finally, the results after joint Aa[right arrow]Ba and Ab[right arrow]Bb training were much greater than those produced by summing the results of Aa[right arrow]Ba training alone and Ab[right arrow]Bb training alone. This same synergy was not observed after joint Aa[right arrow]Bb and Ab[right arrow]Ba training or either alone. (Contains 6 tables and 4 figures.)
