Teaching young children to make accurate portion size estimations using a stimulus equivalence paradigm

Climate Change and Six Americas: What Can Behavior Analysts Do?

Climate change, directly impacted by human behavior, has been investigated and evaluated across disciplines. The Six Americas was developed as a segmentation tool to communicate effectively with the United States population about climate change (Leiserowitz et al., 2021) across a spectrum from those likely to act in opposition to climate change mitigation strategies to those actively seeking to remediate the climate change effects. Behavior analysts offer unique skills to intervene at the individual level effectively. Behavior analysts will benefit from learning about this conceptual model and its tools, particularly to inform intervention across the spectrum of the Six Americas. This paper will cover a background of the Six Americas and suggestions on how to intervene for these different segments at the individual level, followed by a brief review of the existing effective literature, particularly regarding changing behavior in the food, energy, and transportation sectors. Specifically, behavior analytic interventions will be suggested for a population concerned about climate change who may also be posed for action. Finally, we will provide suggestions to guide behavior analysts to intervene with those disengaged or actively dismissive of the threats posed by climate change.

Derived Relational Responding and Transformations of Function in Children: A Review of Applied Behavior-Analytic Journals

Theoretical extensions of Skinner's verbal behavior that emphasize derived relational responding (stimulus equivalence, relational frame theory, and bidirectional naming) can improve the complexity and scope of applied behavior-analytic training models with children. We evaluated the prevalence and content of empirical research on derived relational responding in children within 8 major applied behavior-analytic journals. We identified 123 empirical articles that met all inclusion criteria (i.e., they demonstrated derived relational responding in children). Whereas prior citation analyses have shown higher rates of research with adult participants, considerable research within these journals has involved child participants. In addition, 55% of the research targeted socially relevant or culturally established verbal relations, rather than culturally arbitrary relations (e.g., unknown symbols, consonant-vowel-consonant combinations) that are unlikely to affect real-world behavior. Generalization and transformation tests were also present in 47% of articles. We also conducted a content analysis of all articles that contained culturally relevant relations and demonstrated generalization or transformation of stimulus function (21% of all articles, N = 26); we argue that studies that meet these criteria are likely to be the most immediately impactful for learners. Results suggest that future research is needed to evaluate relational frames other than coordination (e.g., distinction, opposition), as well as to extend considerably the complexity of target relational classes and transformations of stimulus function with children.

Using Stimulus-Equivalence Technology to Teach Skills About Nutritional Content

Twenty-two adult participants, assigned to three conditions, were trained nutrition knowledge (i.e., carbohydrate values) for different food items. In a stimulus sorting test, the participants were asked to sort stimuli (names of food items) into one of three different ranges of carbohydrate values ("less than 20", "20–40", "more than 40" gram per 100 gram). Conditional-discrimination training and testing followed the sorting test, and finally, a postclass formation sorting test of the stimuli used in the conditional-discrimination training. The conditional-discrimination training used tailored stimuli, that is, the food items that each of the participants categorized incorrectly in the sorting test. Participants exposed to Conditions 1 and 2 were trained on six conditional discriminations and tested for the formation of three 3-member classes. Conditions 2 and 3 had a “don’t know” option together with the three different ranges of carbohydrate values in the sorting for tailoring the stimuli. Participants exposed to Condition 3 trained were trained on 12 conditional discriminations and tested for the formation of three 5-member classes. The main findings showed that all but one of the participants responded correctly on at least one test for equivalence class formation and sorted the stimuli correctly in the postclass formation sorting test.

Plating up appropriate portion sizes for children: a systematic review of parental food and beverage portioning practices

Consumption of larger portion sizes is associated with higher energy intake and weight status in children. As parents play a pivotal role in child feeding, we synthesized literature on 'parental portioning practices' using a mixed methods systematic design to inform future strategies addressing portion sizes served to children. Electronic databases PubMed, EMBASE, SCOPUS, PsycINFO and CINAHL Plus were searched. Two reviewers independently screened 385 abstracts and assessed 71 full-text articles against eligibility criteria: studies assessing portioning of foods or beverages by parent(s) with ≥1 child aged 2-12 years. Narrative synthesis of 14 quantitative studies found that portion sizes parents serve vary substantially and are influenced by amounts parents serve themselves, perceived child hunger and parent and child body size. Thematic synthesis of 14 qualitative studies found that parents serve the portion sizes they learn to be appropriate for their child to be fed. Portioning is influenced by parents' desires for a healthy child with a balanced diet. Future guidance on appropriate portion sizes for children would ideally present recommended portion sizes for first serving, incremental with age. Future research is however needed to assess the adoption and efficacy of providing such guidance to families.
