TORRES CHAVEZ, ÁLVARO  and  TOVAR Y ROMO, ÁNGEL. EQUIVALENT CLASS FORMATION VIA VERBAL RULES AND PAPER-AND-PENCIL FORMAT. Act.Colom.Psicol. [online]. 2008, vol.11, n.2, pp.47-53. ISSN 0123-9155.

Equivalent class formation through verbal rules was analyzed. A matching-to-sample procedure for training and probing of conditional discriminations in a "paper and pencil" format was used. Participants were 36 voluntary students, divided in two groups. The baseline training for the experimental group was carried out via verbal rules. This group also received maintenance probes and equivalence probes during the baseline period. The control group was only given the probes. The instrument used proved to be effective. The majority of participants in the experimental group formed two equivalent classes, unlike the control group in which none of the participants showed class formation. The development of effective procedures using "paper and pencil" and verbal rules format, could support the teaching of basic reading skills in large populations with a resulting economy of time and money.

Keywords : stimulus equivalence; matching-to-sample; conditional discrimination; verbal rules; paper-and-pencil format; college students.
