The Effects of Using a Conditioned Stimulus to Cue DRO Schedules

A reversal design was used to examine the effects of a differential reinforcement of other behavior (DRO) procedure and the presence of a stimulus (i.e., a bracelet), conditioned via discrimination training, on reducing socially maintained non‐contextual vocalizations in an adolescent girl with autism. Initially, a functional analysis determined that non‐contextual vocalizations were maintained by social attention. Then, discrimination training was used to establish the presence of the bracelet as a discriminative stimulus for the absence of vocalizations. Specifically, when the bracelet was on, non‐contextual vocalizations were interrupted, and edible reinforcement was provided for the absence of vocalizations. When the bracelet was off, vocalizations were not interrupted and the teacher provided social attention to the participant (i.e., reciprocated conversation with the participant about the topic). During intervention, a DRO procedure was used. The participant was presented with the bracelet, a timer set for a specified interval, and the instruction to work quietly. If vocalizations did not occur for the entire duration of the interval, the bracelet was removed and the learner was given the opportunity to engage in vocalizations. The DRO interval was systematically increased throughout the intervention. Results are discussed in terms of discrimination training as an effective addition to differential reinforcement procedure.

Identifying the role of sociodemographic factors in major depressive disorder and suicidality among Spanish-speaking Latino patients in a federally qualified health center

Rates of suicide and major depressive disorder (MDD) are currently at the highest point in the history of the United States (US). However, these rates are not distributed evenly among the population and Latinos show disproportionately high rates of both suicide and MDD. Yet, past research has infrequently explored factors related to suicide and MDD in primary care settings that serve as the major community portal for mental health among the Latino population. Thus, the current study investigated sociodemographic variables (marital status, nativity, education, employment, primary language, age, and gender) in terms of their relations with suicidal ideation, suicide risk, MDD, and MDD symptom severity among Latino primary care patients in a Federally Qualified Health Center (N = 634, M _age = 39.46, SD = 11.46, 87.1% female). Results indicated that gender and Nativity were associated with suicidal ideation, older age was associated with suicide risk, and higher education and having a partner were negatively associated with MDD and depressive symptom severity. These results provide novel insight into the role of sociodemographic factors predicting suicide and MDD among Latinos in primary care, and suggest greater scientific and clinical attention can be focused on certain sociodemographic factors to offset mental health disparities among this group.     

Global Collaborative Team Performance for the Revision of the International Classification of Diseases: A Case Study of the World Health Organization Field Studies Coordination Group

Background/Objective: Collaborative teamwork in global mental health presents unique challenges, including the formation and management of international teams composed of multicultural and multilingual professionals with different backgrounds in terms of their training, scientific expertise, and life experience. The purpose of the study was to analyze the performance of the World Health Organization (WHO) Field Studies Coordination Group (FSCG) using an input-processes-output (IPO) team science model to better understand the team's challenges, limitations, and successes in developing the eleventh revision of the International Classification of Diseases (ICD). Method: We thematically analyzed a collection of written texts, including FSCG documents and open-ended qualitative questionnaires, according to the conceptualization of the input-processes-output model of team performance. Results: The FSCG leadership and its members experienced and overcame numerous barriers to become an effective international team and to successfully achieve the goals set forth by WHO. Conclusions: Research is necessary regarding global mental health collaboration to understand and facilitate international collaborations with the goal of contributing to a deeper understanding of mental health and to reduce the global burden of mental disorders around the world.     

Emotional processing in people with obsessive-compulsive symptomatology

The present study was aimed at assessing obsessive-compulsive symptomatology based on visualization of affective pictures, elaborated following Peter Lang's dimensional model of emotion. Participants were 370 psychology students at Malaga University, selecting those with high and low scores in obsessive-compulsive symptomatology. All participants assessed a set of pictures containing obsessive-compulsive cues using the three scales of the Self-Assessment Manikin: affective valence, arousal, and control/dominance. The results show that participants with high scores in obsessive-compulsive symptomatology experience reduced control over the affective pictures and rate as more unpleasant the neutral and obsessive-compulsive pictures.     

Objective and subjective measures indicate that orthographically similar words produce a blocking experience

Memory blocks are a common experience characterised by inappropriate retrieval of information that impairs memory search processes. In five studies, memory blocks were induced via exposure to orthographically similar words (Smith & Tindell, 1997) while participants reported their subjective experiences to determine whether the memory block effect (MBE) paradigm produces a feeling of being blocked. Experiments 1 and 3 provided evidence that the MBE is associated with more blocked experiences. In Experiments 2 and 4 increased blocking experiences correlated with blocked fragments when the experimental manipulation was disguised, which demonstrates that ratings were not contaminated by demand characteristics. Experiment 5 demonstrated that blocking happens even when there is no study list. Collectively, the subjective retrieval ratings and the objective response data provide converging evidence that exposure to orthographically similar words induces a memory block characterised by an ineffective memory search that perseverates on interfering information.     

Can Constructive Thinking Predict Decision Making?

We assume that executive function constitutes an integrated set of cognitive processes that mediate working memory, planning, inhibition, flexibility, and decision making. Despite the acknowledged theoretical connection between executive function processes and emotional intelligence, such relationships have rarely been investigated. The purpose of this study was to examine the potential relationship between constructive thinking, conceived as a component of emotional intelligence, and executive function, as indexed by various existing neuropsychological and experimental instruments. We used the Constructive Thinking Inventory as a measure of emotional intelligence. We found that some constructive thinking subscales were able to predict distinct executive function variables. Emotional Coping, Categorical Thinking, and Esoteric Thinking subscales explained performance on various measures of executive function. Thus, we conclude that intervention programs designed to train a specific component of emotional intelligence, namely constructive thinking, could also facilitate performance in executive function processes, and vice versa.

Confidence and accuracy of lineup selections and rejections: Postdicting rejection accuracy with confidence

Correlation and calibration approaches show meaningful, positive confidence-accuracy relations for witnesses making selections from lineups, but rarely for rejections (Brewer and Wells, 2006, Sauerland and Sporer, 2009). This disparity may reflect the difference between selecting a single photo versus rejecting a set of photos. Participants (N = 101) in two experiments made selections from and rejections of lineups in situations requiring either a single confidence rating about a single face (typical of “choosers”) or a single confidence rating about multiple faces (typical of “nonchoosers”). Mean confidence ratings were significantly higher for accurate versus inaccurate decisions for both selections and rejections when decisions were based on single faces. Single decisions about multiple faces produced no significant difference in confidence between correct and incorrect rejections but a significant difference for selections.     

The Ethics of Ethics Reviews in Global Health Research: Case Studies Applying a New Paradigm

With increasing calls for global health research there is growing concern regarding the ethical challenges encountered by researchers from high-income countries (HICs) working in low or middle-income countries (LMICs). There is a dearth of literature on how to address these challenges in practice. In this article, we conduct a critical analysis of three case studies of research conducted in LMICs. We apply emerging ethical guidelines and principles specific to global health research and offer practical strategies that researchers ought to consider. We present case studies in which Canadian health professional students conducted a health promotion project in a community in Honduras; a research capacity-building program in South Africa, in which Canadian students also worked alongside LMIC partners; and a community-university partnered research capacity-building program in which Ecuadorean graduate students, some working alongside Canadian students, conducted community-based health research projects in Ecuadorean communities. We examine each case, identifying ethical issues that emerged and how new ethical paradigms being promoted could be concretely applied. We conclude that research ethics boards should focus not only on protecting individual integrity and human dignity in health studies but also on beneficence and non-maleficence at the community level, explicitly considering social justice issues and local capacity-building imperatives. We conclude that researchers from HICs interested in global health research must work with LMIC partners to implement collaborative processes for assuring ethical research that respects local knowledge, cultural factors, the social determination of health, community participation and partnership, and making social accountability a paramount concern.     

Discriminative game-related statistics between basketball starters and nonstarters when related to team quality and game outcome

The aim of the present paper was to examine the differences in game-related statistics between basketball players who are selected for the starting five of the team (starters) and those who are not (nonstarters) when related to game outcome (winning and losing) and team quality (best teams, teams classified for the playoffs; and worst teams, teams who miss playoff classification). Archival data were gathered for all 2002-2003 regular season games from the Portuguese Professional League (N = 156). Discriminant analysis was used to identify the game-related statistics that differentiate between starters and nonstarters and interpreted by the examination of the structure coefficients (SC). When the best teams won the games, results described differences between starters and nonstarters with an emphasis on defensive rebounds (SC = .32), assists (SC = .32) and committed fouls (SC = -.68). When the worst teams won the games, results described differences between starters and nonstarters with an emphasis on 2-point field goals successful (SC = .47) and unsuccessful (SC = .48), defensive rebounds (SC =.39), successful free throws (SC =.32), and committed fouls (SC = -.55). An also important finding was that, in best teams, the nonstarters' performance was worse in the games that the team lost, whereas in worst teams, it was the starters' performance that was worse in the games that the team lost.
