Abstract:	The emergence of transitivity-indicative performances occasioned by novel probes was observed following exposure to multiple-exemplar transitivity training and/or staged testing for transitivity. Twenty-four of 101 college students failed to demonstrate transitivity-indicative performances in an initial test that contained 6 stimulus sets drawn from 3 domains: glyphs, satellite images, and nonsense syllables, each of whom was assigned to 1 of 4 experimental conditions. Subjects in Condition 1 did not receive any intervention. Subjects in Condition 2 received transitivity training with 20 new glyph sets. Subjects in Condition 3 were reexposed to the stimuli from the initial test, but with one domain at a time (i.e., staged testing). Subjects in Condition 4 received both transitivity training and staged testing. Finally, all subjects were reexposed to the initial test (i.e., posttest). The number of subjects and the number of stimulus sets in the posttest that occasioned transitivity-indicative responding did not change for subjects in Condition 1, showed moderate increases for subjects in Conditions 2 and 3, and showed large increases for subjects in Condition 4. The improvements in Conditions 2 and 3, however, varied with stimulus domain. Improvements were minimal for the glyph stimuli, moderate for the satellite stimuli, and largest for the nonsense syllables. Thus, the emergence of a generalized transitivity repertoire was influenced by an interaction between transitivity training, test repetition, and the perceptual similarities of the stimuli used for testing.
