In two instrumental conditioning experiments with rats, we examined the impacts of acquisition and extinction cues on ABC renewal of instrumental behavior. Animals were reinforced with food for lever pressing in one context, followed by extinction of the response in a second one. Presentations of a brief tone accompanied extinction in Experiment 1…

Aim: This study aims to evaluate the impact of a novel multicomponent nutrition education program (United for Healthier Kids; U4HK) on the diet consumed during school lunch among preschool children. Methods: The program comprised four tools: hero plates, hero content, hero menus, and hero books and stickers. The program was implemented for 16…

Behavioral flexibility is important in a changing environment. Previous research suggests that systems consolidation, a long-term poststorage process that alters memory traces, may reduce behavioral flexibility. However, exactly how systems consolidation affects flexibility is unknown. Here, we tested how systems consolidation affects: (1)…

Motivationally attractive cues can draw in behavior in a phenomenon termed incentive salience. Incentive cue attraction is an important model for animal models of drug seeking and relapse. One question of interest is the extent to which the pursuit of motivationally attractive cues is related to the value of the paired outcome or can become…

Food selectivity affects up to 72% and 45% of individuals with and without disabilities, respectively, and there is a need for interventions that rely on positive, unrestrictive strategies. We evaluated an assessment and treatment package for food selectivity for young children with developmental disabilities that prioritized caregiver…

Early studies evaluating the relative preference for leisure compared with edible items suggested that, for most participants (>80%), edible items are more preferred than leisure items. Recent studies suggest more variability in the percentage of participants with this preference. The rationale for this variability could be sampling, setting,…

Challenging behaviors involving food are common for individuals with Prader-Willi syndrome (PWS) and often lead to obesity and other chronic health conditions. Efforts to decrease these behaviors, such as isolation during meals and strict monitoring of food consumption, can be stigmatizing. To decrease the food stealing of a 7 year-old girl with…

Social skills--including the ability to participate appropriately in social activities--are predictive of later social and academic success and critical for children to successfully engage in typical early childhood contexts. For children with disabilities, deficits in social skills are not uncommon. To address the relation between social skills…

Background: People with intellectual disabilities are more at risk of obesity than the general population. Emerging literature indicates that multicomponent interventions are most effective, however, individual results are variable and little research exists as to why this is the case. Methods: Focus groups were conducted to explore lived…

When discrete localizable stimuli are used during appetitive Pavlovian conditioning, "sign-tracking" and "goal-tracking" responses emerge. Sign-tracking is observed when conditioned responding is directed toward the CS, whereas goal-tracking manifests as responding directed to the site of expected reward delivery. These…

The current study used differential reinforcement and shaping to increase the variety of foods accepted by children with autism who demonstrated significant feeding inflexibility. Participants were introduced to four new food items via a hierarchical exposure, which involved systematically increasing the desired response with the food item. Level…

Rates of inclusion for children with disabilities continue to increase. Schools are also experiencing an increase in culturally and linguistically diverse students. As such, the diversity of children in classrooms across the country continues to dramatically shift and teachers are challenged to implement culturally responsive and relevant…

Nudge theory describes how indirect suggestions and positive reinforcement can influence decision-making. We used nudge theory to implement a traffic-light labeling and choice architecture (modifying product placement) intervention at Harvard University cafeterias, but found no significant change in sales. Survey and focus group data showed that…

Foodborne diseases are a global burden, are preventable, and young people are a key population for behaviour change as they gain autonomy. This study aimed to explore young people's needs across several European countries in relation to learning about and implementing food hygiene and food safety. Qualitative focus groups and interviews were…

We examined the effects of reinforcement magnitude on skill acquisition during discrete-trial training. After conducting a magnitude preference assessment, we compared acquisition during conditions with large and small magnitudes of edible reinforcement to a praise-only condition. Although all participants showed a preference for the…
