The emergence of equivalence relations and the role of overall verbal competence and stimulus nameability and familiarity in this regard were investigated across 3 experiments involving 15 children diagnosed with autistic spectrum disorder (ASD), as well as 3 typically developing children. The experimental sequence comprised 4 identical stages,…

The current study examined the malleability of implicit attitudes using the Implicit Relational Assessment Procedure (IRAP). In Experiment 1, "similar" and "opposite" were presented as response options with the sample terms "old people" and "young people" and various positive and negative target stimuli.…

The current article reports the first attempt to test the Implicit Relational Assessment Procedure (IRAP), as a group-based measure of natural verbal relations, using both response-latency and event-related potentials as dependent variables. On each trial of the IRAP, participants were presented with 1 of 2 attribute stimuli ("Pleasant"…

Recent research has demonstrated the transfer of induced mood functions through equivalence relations by means of a musical mood-induction procedure. The research described in this article replicated and extended such work, primarily with the inclusion of a baseline and two types of reversal procedures. First, 16 adult participants were trained…

Investigators examined the role of deictic complexity in the context of false-belief understanding. Deictic relations (i.e., I and YOU, HERE and THERE, and NOW and THEN) are used to describe one's perspective on events in the environment. Differences in complexity between responding in accordance with "I" (self) and "YOU" (other) relations are…

The current article examines patterns of adult responding to different types of more-than and less-than relations, as well as procedures for facilitating responding in accordance with these relations. Using parameters suggested in the three-term series literature, the more-than and less-than relations were separated into six distinct trial types.…

The current study consisted of 2 parts, with the same 4 normally developing 4-yr-old children employed across both parts. The primary aim of Part 1 was to replicate previous research on exemplar training and its impact upon the emergence of repertoires of derived symmetry or mutually entailed relations. In this part of the study, the children were…

The present study investigated the transfer of induced happy and sad mood functions through equivalence relations. Sixteen subjects participated in a combined equivalence and mood induction procedure. In Phase 1, all subjects were trained in 2 conditional discriminations using a matching-to-sample format (i.e., A1-B1, A2-B2, A1-C1, A2-C2). In…
