Social facilitation in young toddlers

As a test of Zajonc's social facilitation hypothesis, the behavior of 18 young toddlers (16-24 mo.) was observed. Their performance on a simple task was incongruent with his hypothesis, that is, these young toddlers may not evaluate their outcomes in relation to a social standard.     

Roles of salience and strategy in conjunction search

In some cases, the search for a conjunction target proceeds through the smaller group of elements in a display, whereas in others, search is limited to those elements that share a particular feature with the target. In 6 experiments, participants searched for a conjunction target among displays consisting of various proportions of 2 distractor types. Smaller-group search was more prevalent than target-feature search with denser displays and with features that were highly discriminable. Explicit instructions to limit search to a specific feature affected performance only when the discriminability of the guiding feature was much greater than the other target feature. Together, these experiments show that bottom-up factors have more influence in guiding conjunction searches than previously thought.     

Teaching General Safety and Body Safety Training Skills to a Latino Preschool Male with Autism

This case study describes the implementation of a safety training program with a 5-year-old Latino boy diagnosed with Autism Spectrum Disorder. The program focused on teaching him general safety rules and body safety in an effort to reduce his likelihood of sexual victimization and injury. The boy was treated in conjunction with another child by two therapists, while his caretakers participated in a caretaker group. Both groups consisted of 10 h of safety education instruction. Results show that the boy was able to learn a few safety concepts as well as increase his knowledge of personal safety. Caregiver data revealed a minor increase in knowledge of general safety and an increase in family communication regarding safety issues. However, upon a 3-month follow-up, the boy appeared to lose some knowledge. Recommendations for implementing the Body Safety Training program with children with disabilities and providing their caretakers with information regarding the risk of child sexual abuse is provided.     

Perceptual identification and the cross-race effect

The current research examined whether the cross-race effect (CRE) was evident in perceptual identification tasks and the extent to which certain boundary conditions moderated the effect. Across two experiments, a significant CRE was observed in measures of accuracy and response latency. As predicted, Experiment 1 showed that the CRE was exacerbated when encoding time was brief and test set size was increased. Experiment 2 replicated the effect of set size, but also showed that the CRE was more pronounced when the retention interval was lengthened. The theoretical and practical implications of the results are discussed.     

An Experiential, Game-Theoretic Pedagogy for Sustainability Ethics

The wicked problems that constitute sustainability require students to learn a different set of ethical skills than is ordinarily required by professional ethics. The focus for sustainability ethics must be redirected towards: (1) reasoning rather than rules, and (2) groups rather than individuals. This need for a different skill set presents several pedagogical challenges to traditional programs of ethics education that emphasize abstraction and reflection at the expense of experimentation and experience. This paper describes a novel pedagogy of sustainability ethics that is based on noncooperative, game-theoretic problems that cause students to confront two salient questions: “What are my obligations to others?” and “What am I willing to risk in my own well-being to meet those obligations?” In comparison to traditional professional ethics education, the game-based pedagogy moves the learning experience from: passive to active, apathetic to emotionally invested, narratively closed to experimentally open, and from predictable to surprising. In the context of game play, where players must make decisions that can adversely impact classmates, students typically discover a significant gap between their moral aspirations and their moral actions. When the games are delivered sequentially as part of a full course in Sustainability Ethics, students may experience a moral identity crisis as they reflect upon the incongruity of their self-understanding and their behavior. Repeated play allows students to reconcile this discrepancy through group deliberation that coordinates individual decisions to achieve collective outcomes. It is our experience that students gradually progress through increased levels of group tacit knowledge as they encounter increasingly complex game situations.     

The Southern Pub Crawl and Brawl: An Examination of the Alcohol–Violence Nexus in a Southern City

This research examines the relationship between alcohol availability and crime, specifically the variation of effects between the presence of off- and on-site establishments on violent crime. We contribute to extant research by providing a more comprehensive disaggregation of alcohol establishments. Framed in routine activities theory, we argue that alcohol availability will exacerbate violent crime rates by increasing quantities of motivated offenders and suitable targets, while simultaneously decreasing the number of capable guardians. We find a nuanced relationship between the presence of alcohol establishments and violence that varies based on establishment type as well as the characteristics of its block group.     

Trends in Behavior-Analytic Gambling Research and Treatment

The purpose of the present review was to analyze research outcomes for all gambling studies reported in the behavior analysis literature. We used the search term “gambling” to identify articles that were published in behaviorally oriented journals between the years 1992 and 2012 and categorized the content of each article as empirical or conceptual. Next, we examined and categorized the empirical articles by inclusion of an experimental manipulation and treatment to alleviate at least some aspect of pathological gambling, participant population used, type of gambling task employed in the research, whether the participants in the study actually gambled, and the behavioral phenomena of interest. The results show that the rate of publication of gambling research has increased in the last 6 years, and a vast majority of articles are empirical. Of the empirical articles, examinations of treatment techniques or methods are scarce; slot machine play is the most represented form of gambling, and slightly greater than half of the research included compensation based on gambling outcomes within experiments. We discuss implications and future directions based on these observations of the published literature.     

Reducing Identity Distress: Results of an Identity Intervention for Emerging Adults

Emerging adulthood is a transitional period between adolescence and adulthood where positive and negative life trajectories tend to diverge, with issues surrounding identity formation playing a key role. The present study evaluated the Miami Adult Development Project, a self-facilitated identity-focused intervention. The sample consisted of 141 emerging adults (19?29 years old; M = 23.08) who completed pretest and posttest assessments. Results indicated participation in the intervention relative to the comparison group was associated with lower levels of identity distress and higher levels of well-being via the reduction of identity distress and the development of a consolidated identity (commitment and synthesis). The present study provides evidence for the effectiveness of positive identity interventions during emerging adulthood.
