Studies conducted have documented the formation of ordinal classes in humans through the teaching of independent sequences. Teaching sequences for overlapping pairs (e.g. A1A2, A2A3, A3A4, A4A5) may be the basis for the formation of ordinal relations within and between sequences unequivocally. The objective of this study was to replicate the teaching procedure by overlapping trios of stimuli, from the expansion of ordinal classes in three preschoolers. We used two sets of stimuli: one with cardinal numbers 1 to 9 and another with non-representational forms in these quantities. Software was used in the presentation of stimuli and recording responses. A notebook with 15' screen presented animated videos contingent to each hit. Tests of transitivity (eg, 3-5-7 or 5-7-9) were presented after teaching overlap with sequences of three stimuli (eg 1-2-3, 3-4-5, 5-6-7, 7-8-9). The second set of stimuli was presented with the same sequence of training and testing. Then the connectivity test was applied. Results showed that three participants responded with 100% accuracy in most tests. These results also suggest a baseline programmed correctly.
