The purpose of the current study was to extend the research on the possible role of verbal mediation in the establishment of comparative relations. We conducted four experiments in which 14 participants received conditional discrimination training with nonarbitrary and arbitrary stimuli, followed by derived comparative and transformation of function tests. Participants learned to select the smallest or biggest comparison across multiple exemplars in the presence of abstract samples. Next, participants learned to select arbitrary comparisons in the presence of contextual cues to establish a size ranking among comparisons. To assess verbal mediation during mutual and combinatorial entailment tests, participants were instructed to talk out loud. When they failed to perform correctly during derived relations tests, participants were trained to tact and intraverbally relate stimuli. The results suggest that relational training alone was not sufficient to establish comparative relations and that adult participants engaged in problem solving consistent with intraverbal bidirectional naming during emergent relations tests.

Resurgence can be defined as increases in previously reinforced and subsequently extinguished target responding when conditions for an alternative response worsen. Worsening of alternative conditions, such as extinction, has been linked to relapse of clinically relevant behavior. Preclinical researchers have evaluated whether punishing target responses while differentially reinforcing an alternative response could reduce resurgence when conditions are worsened with extinction, with mixed results. In the present investigation, we systematically replicated this line of research with human participants recruited via crowdsourcing, using response cost as punishment. During Phase 1, we reinforced target responses with 100 points per delivery, exchangeable for money. During Phase 2, we reinforced alternative responses, discontinued point reinforcement for target responses, and parametrically manipulated across groups the magnitude of point loss (1, 100, 320, or 1,000 points) contingent on target responses. During Phase 3, we tested for resurgence by extinguishing target and alternative responses. Added punishment systematically decreased target responding during Phase 2 but did not influence resurgence during Phase 3. With a meta-analysis, we compared our findings with existing research examining a range of punishers and species. The results of the meta-analysis comport with the present findings, suggesting that the inclusion of punishment reduces target responding during DRA but, overall, has no systematic effects on resurgence.

The principles of social justice, equity, diversity, inclusion (JEDI) have received increasing attention in behavior analysis circles, but the conversation has largely centered on implications for applied behavior analysis practice and research. It may be less clear to researchers who conduct basic and translational research how JEDI principles can inform and inspire their work. This article synthesizes publications from behavior analysis and other scientific fields about tactics of JEDI-informed research. We organized this scholarship across five stages of research from developing the research question to sharing findings and curated sources for an audience of behavioral science researchers. We discuss reflexive practice, representation, belongingness, participatory research, quantitative critical theory, and open science, among other topics. Some researchers may have already adopted some of the practices outlined, some may begin new practices, and some may choose to conduct experimental analyses of JEDI problems. Our hope is that those actions will be reinforced by the behavior analysis scientific community. We conclude by encouraging the leadership of this journal to continue to work toward the structural changes necessary to make the experimental analysis of behavior just, equitable, diverse, and inclusive.

Literature concerning operant behavioral economics shows a strong preference for the coefficient of determination (R²) metric to (a) describe how well an applied model accounts for variance and (b) depict the quality of collected data. Yet R² is incompatible with nonlinear modeling. In this report, we provide an updated discussion of the concerns with R². We first review recent articles that have been published in the Journal of the Experimental Analysis of Behavior that employ nonlinear models, noting recent trends in goodness-of-fit reporting, including the continued reliance on R². We then examine the tendency for these metrics to bias against linear-like patterns via a positive correlation between goodness of fit and the primary outputs of behavioral-economic modeling. Mathematically, R² is systematically more stringent for lower values for discounting parameters (e.g., k) in discounting studies and lower values for the elasticity parameter (α) in demand analysis. The study results suggest there may be heterogeneity in how this bias emerges in data sets of varied composition and origin. There are limitations when using any goodness-of-fit measure to assess the systematic nature of data in behavioral-economic studies, and to address those we recommend the use of algorithms that test fundamental expectations of the data.

This note discusses the apparently unpublished correspondence between B. F. Skinner and the Belgian psychologist Albert Michotte, preceding Skinner's visit to the Thirteenth International Congress of Psychology in Stockholm in 1951. Skinner's letters, written in French, were intended to arrange a visit to Michotte's laboratory in Leuven (then called Louvain) in Belgium, which in the end never took place, although it seems highly likely that they met in Stockholm. There is no record of the topic of the conversations they may have had, although one possible speculation concerns discussions of causality, as both Skinner and Michotte had published work relating to this topic in the 1940s, Michotte's La Perception de la Causalité and Skinner's Superstition in the pigeon. The note also discusses the way in which Skinner's visit to the Thirteenth Congress influenced the development of the experimental analysis of behavior in both Europe and Japan.

Visual imagining has been proposed to play a role in the emergence of derived stimulus relations. We examined whether test-relevant visual imagining during baseline training would, accordingly, facilitate emergent visual–visual conditional discriminations at test. Adult participants (n = 75) were randomly assigned to three groups. Baseline tact training established conditional discriminations among sets of image samples and textual comparisons (AC/BD), and baseline intraverbal training established conditional discriminations among pairs of textual stimuli (CD). Two groups received tact before intraverbal training, and one group received the reverse sequence. During intraverbal training, one of the former groups was instructed to visualize the images that went with the textual stimuli. These instructions did not affect participants' retrospective self-reports of test-relevant visual imagining during training. Nevertheless, they produced a large effect on correct responding in an image-matching test (AB/BA) that followed intraverbal training. This effect was independent of baseline retention.

In this article, we describe a mediational theory of emergent or derived relations resulting from matching-to-sample procedures that produce equivalence and transformation of function. According to a mediational theory, behaviors that occur at the time of reinforcement mediate subsequent behavioral relations referred to as “derived” or “emergent.” Such relations have been documented for decades in studies using mostly matching-to-sample procedures with humans and nonhumans. In both verbal human and nonhuman participants, the mediating behaviors consist of differential responding to the sample stimulus. In humans, such behaviors are mostly, but not necessarily, verbal; in nonhumans they include a variety of sample-specific responses, sometimes called “coding.” The proposed mediational theory, based only on the four-term contingency and the basic principles of operant learning, makes specific predictions and explains results from a broad range of experiments. There are at least three important implications of a mediational theory. First, if by “derived” or “emergent” one means untrained or unreinforced, then derived relations may not exist. Second, if there are no derived relations, then theories of such relations may not be necessary. Third, a mediational theory of relational responding has potentially important implications for clinical practice.
