Implicit and Explicit Measures of Transformation of Function from Facial Expressions of Fear and of Happiness via Equivalence Relations

How to Build and How not to Build an Implicit Measure in Behavior Analysis: A case Study Using the Function Acquisition Speed Test

This article provides a comprehensive overview of the development of a behavior-analytic alternative to the popular implicit association test (IAT), namely, the function acquisition speed test (FAST). The IAT appears, prima facia, to indirectly assess participants' learning histories with regard to the categorization of stimuli. However, its origin within cognitive psychology has rendered it replete with mentalism, conceptual ambiguity, statistical arbitrariness, and confounding procedural artifacts. The most popular behavioral alternative to the IAT, the widely used implicit relational assessment procedure (IRAP), has inherited many of these concerning artifacts. In this article, we present a behavior-analytic critique of both the IAT and IRAP, and argue that a behavior-analytic approach to implicit measures must have stimulus control front and center in its analysis. We then outline a series of early research studies that provided the basis for a potentially superior procedure within our field. We go on to outline how this early research was harnessed in stepwise research, guided by a strict adherence to traditional behavior-analytic methods for the analysis of stimulus relations, to increasingly modify a test format fit for the behavior analyst interested in assessing stimulus relatedness.

Variables involved in the acquisition and maintenance of racial aggression and its victims' reactions

This study aimed to investigate how behavior analysis can contribute to the understanding of some variables and processes involved in the acquisition and maintenance of racial aggressors' behaviors, as well as the victims' reactions. We describe how the concepts of rule-governed behavior and motivating operations may be involved in institutional racism: Individuals belonging to ethnic groups who hold the social administration in a context may keep important reinforcers available for their own group, while other racial groups may have their access to those reinforcers hindered. For these privileges to be perpetuated, the ruling group can arrange contingencies that reinforce the behavior of following certain rules that contribute to the maintenance of relevant reinforcers for the ruling group and exclusion of Black individuals and other people of color. For those underrepresented groups, motivating operations can be manipulated and reinforcers can be provided only when their responses are deemed appropriate by the dominant group. Individual learning through discriminative training, equivalence class formation, transfer of functions, stimulus generalization, and function altering were also discussed. Patterns such as aggression, escape, and avoidance, were identified in the actions of racial aggressors. Finally, the victim's reactions were also identified as escape, avoidance, or aggression of racial aggressors, but also as effects of processes such as learned helplessness, extinction after elimination of benefits, countercontrol, and respondent conditioning. Despite the lack of research in the field, behavior analysis has the power to elucidate some variables related to this theme, aiding, thus, evidence-based intervention proposals.

Equivalence relations and the contextual control of multiple derived stimulus functions

Contextual control is a key aspect in equivalence research to support the claim that stimuli may have multiple functions or symbols may have multiple meanings. The present study investigated the contextual control of multiple derived stimulus functions in two experiments. In Experiment 1, equivalence classes were formed and one stimulus set from each class was used to establish two different functions: one via positive reinforcement (key-pressing) and another via negative reinforcement (button clicking), both under contextual control of two different background colors. Later, other stimuli from the equivalence class were presented on those background colors and contextual control of multiple derived stimulus functions was assessed. Experiment 2 added a third background in which no programmed response was reinforced, that is, responses were extinguished. Transfer-of-function tests revealed contextual control of three different functions, including derived extinction. Implications for equivalence relations as a behavior-analytical model of symbolic functioning are discussed.
