AbstractBehavioral interventions for animals typically require the inclusion of programmed reinforcers. Although pet owners and human caregivers can often identify items that the animal will consume, preference assessments can more accurately determine relative preference rankings between various stimuli, which is important given that higher preferred items tend to function as more effective reinforcers than lower preferred items. Preference assessments have been developed to identify rankings for a variety of stimuli across species, including the domesticated dog (Canis lupus familiaris). However, previous preference assessments for dogs were developed for laboratory use and could be challenging for dog owners to perform alone. The purpose of this study was to modify existing dog preference assessment methods to produce a valid and feasible preference assessment for dog owners. Results suggest that the preference assessment identified preference rankings for individual dogs. Owners were able to implement the protocol with high integrity and found the protocol acceptable.

Neste trabalho, busco apresentar e discutir argumentos e problematizações de três textos em que o Prof. J. A. D. Abib explora potencialidades e limites de uma compreensão da subjetividade em uma perspectiva comportamentalista radical. Com especial enfoque na transcrição de uma comunicação proferida na XVIII Reunião Anual da Sociedade de Psicologia de Ribeirão Preto, destaco as premissas apresentadas por Abib que poderiam fun­damentar uma proposta comportamentalista radical para o problema do conhecimento da subjetividade; bem como exploro e amplifico as discussões sobre como o compromisso com as noções de acesso e privacidade corrompem essa possibilidade. Diante desse quadro, apre­sento a provocação do autor sobre a potencialidade de revisão crítica da proposta compor­tamentalista radical com base no encontro com a noção de intencionalidade da consciência, a partir da tradição fenomenológico-existencial. Por fim, transcrevo a proposta de itinerário de pesquisa indicado por Abib para a exploração dessa possibilidade para avançar os limites da proposta comportamentalista radical na consideração da subjetividade.

AbstractPica is a severe behavior disorder involving the persistent consumption of nonnutritive substances. Due to health complications and risks for fatality, designing effective behavioral treatments that are feasible for implementation by family members at home is imperative. This case report presents a parent‐conducted functional analysis and treatment evaluation of automatically maintained pica in a teenager with autism spectrum disorder. Initial treatment with a competing stimulus was effective when paired with response interruption and redirection. Although effective, this combination of treatment components required very close parental proximity and led to increases in untargeted body‐oriented pica (e.g., ingestion of skin, hair, and nails). Upon extending treatment to include the second topography of pica, both the originally targeted (object‐oriented) pica and body‐oriented pica decreased. Nonetheless, treatment effects were not sustained while fading parent proximity. The treatment was then augmented a third time with response cost. This final treatment package produced clinically significant reductions in all pica, facilitated parent proximity fading until the participant was alone, extended to their home, and maintained over a year of follow up.

AbstractPrior work has demonstrated canine search behavior and performance declines when challenged with infrequent target odors. The purpose of this study was to evaluate whether performance could be maintained in a low target odor prevalence context by explicitly training dogs through progressively leaner target odor schedules. In Experiment 1, nine control dogs were trained at 90% target prevalence rate. Nine experimental dogs were trained with progressively lower prevalence rates in 10% increments until reaching 20% prevalence with > 85% detection accuracy in the training context. Both groups were tested in the operational context at a 10% target odor prevalence. Experimental dogs had higher accuracy, hit percentage, and shorter search latency in the operational context compared with control dogs. In Experiment 2, twenty‐three operational dogs were challenged with a target frequency of 10%, which resulted in 67% accuracy. Control dogs were then trained with 90% target frequency, whereas experimental dogs received a progressively decreasing target rate from 90% to 20%. The dogs were rechallenged with target frequencies of 10, 5, and 0%. Experimental dogs outperformed control dogs (93% vs. 82% accuracy) highlighting the effect of explicit training for infrequent targets.

AbstractConditioned reinforcers are widely used in applied behavior analysis. Basic research evidence reveals that Pavlovian learning plays an important role in the acquisition and efficacy of new conditioned‐reinforcer functions. Thus, a better understanding of Pavlovian principles holds the promise of improving the efficacy of conditioned reinforcement in applied research and practice. This paper surveys how (and if) Pavlovian principles are presented in behavior‐analytic textbooks; imprecisions and knowledge gaps within contemporary Pavlovian empirical findings are highlighted. Thereafter, six practical principles of Pavlovian conditioning are presented along with empirical support and knowledge gaps that should be filled by applied and translational behavior‐analytic researchers. Innovative applications of these principles are outlined for research in language acquisition, token reinforcement, and self‐control.
