Sequential cotherapy of groups for training and clinical care

Cotherapy has often been used as the leadership model in group therapy. The literature is full of contradictory data and impressions as to the efficacy of this model. In this article a new form of cotherapy is presented which may offer some of the assets attributed to the cotherapy leadership model while at the same time reducing some of the liabilities. Sequential cotherapy refers to cotherapy when each of the therapists leads sequentially rather than at the same time. The pros and cons of such an approach are discussed from both the perspectives of training new group therapists and of service to patients in groups.Dr. Rutan and Mrs. Alonso are members of the faculty of Harvard University Medical School and share responsibility for training psychiatric residents in group therapy at Massachusetts General Hospital, Boston, Massachusetts.     

Watching the best nutcrackers: what capuchin monkeys (Cebus apella) know about others’ tool-using skills

The present work is part of a decade-long study on the spontaneous use of stones for cracking hard-shelled nuts by a semi-free-ranging group of brown capuchin monkeys (Cebus apella). Nutcracking events are frequently watched by other individuals--usually younger, less proficient, and that are well tolerated to the point of some scrounging being allowed by the nutcracker. Here we report findings showing that the choice of observational targets is an active, non-random process, and that observers seem to have some understanding of the relative proficiency of their group mates, preferentially watching the more skilled nutcrackers, which enhances not only scrounging payoffs, but also social learning opportunities.     

Relationship between fine/gross motor skills and language and math development in Colombian Caribbean children: A study in Barranquilla

Literature suggests that motor skills are associated with other areas of development or domains, such as language and math, especially at early ages. These results are mainly based on studies developed in medium-to-high sociocultural contexts. Thus, this study was conducted in a medium-to-low-income area. The aim was to know the 4–5 years old children's motor development (both fine and gross motor skills), and its relation to language and mathematical development. A total of 219 Colombian Caribbean children (105 boys and 114 girls) aged 4 and 5 years participated in this study. Results revealed higher motor skills among girls, although differences by gender were not notable. Positive and significant correlations were found between motor skills and language and mathematical skills, although most of the correlations were weak or moderate. Also, it was observed that fine motor skills were less related to language or mathematical development in comparison with gross motor skills, especially among boys. These results suggest that among Colombian Caribbean children gross motor skills could have a higher influence on the development and acquisition of some language and mathematical skills in comparison with fine motor skills.     

Why do we share aggressive online content? Testing a short cycle model

The present study aimed to observe the impacts of aggressive online content exposure and personality on aggressive content sharing, considering the mediating role of positive and negative affects. A total of 302 Brazilians, equally divided into two groups, participated in a social network simulation, being exposed to aggressive (experimental group) or neutral (control group) posts and choosing what they would like to share on this site (among aggressive or nonaggressive material). A factorial MANOVA showed a significant difference for positive and negative affects and aggressive content sharing (Wilks' Λ = 0.936; F[3, 298] = 6.812; p = .001; η² = 0.064). Through structural equation modeling, an explanatory model was also tested, in which this behavior was directly predicted by aggressive online content exposure and suffered indirect effects from openness, conscientiousness, and extroversion, mediated by positive affects (goodness-of-fit index = 0.997, comparative fit-index = 0.998, Tucker-Lewis index = 0.996, SRMR = 0.028, root-mean-square error of approximation = 0.035, CI = 0.003−0.054). It is possible to conclude that the objectives are met, highlighting the contribution to understanding aggressive online behavior through the proximal processes described in the general aggression model.     

Effect of observing response requirements to sample and comparison stimuli on the establishment of reject control (sample/S- relations)

The establishment of sample/S- relations (or reject control) during conditional discrimination training (AB, BC) affects transitivity (AC), equivalence (CA) and reflexivity (AA, BB, CC) test outcomes. The present study parametrically evaluated the effects of different observing patterns to comparison stimuli on the establishment of reject control during baseline conditional relation training. A matching-to-sample with observing requirements (MTS-OR) procedure was implemented during AB and BC conditional discrimination training. During training, the participants were required to observe the sample and incorrect comparison on every trial before responding. In addition, the participants were divided into three groups that differed regarding the percentage of training trials on which they were prevented from observing the correct comparison stimuli: 25%, 50%, and 75%. Once the mastery criteria were achieved during training, transitivity (AC), symmetry (BA, CB), equivalence (CA), and reflexivity (AA, BB, CC) tests were conducted with all comparison stimuli visible from the beginning. The results suggest that the number of errors during transitivity, equivalence, and reflexivity tests progressively increased as participants were prevented from observing the correct comparison on a greater number of trials during training. Symmetry test results, however, were not affected by the experimental manipulation. Moreover, the number of participants showing reject-control patterns during tests slightly increased and the number of participants showing select-control patterns decreased as a function of the number of trials on which the participants were prevented from observing the correct comparison. Thus, we suggest that observing patterns during training is a relevant variable that affects equivalence test outcomes.     

Relative age effect in Olympic Taekwondo athletes

Relative age effects refer to the effects of age differences among individuals who have been grouped together for a performance activity. This study aimed to investigate the relative age effect on Olympic Taekwondo athletes, in several Olympic Games, and in both sexes. The study sample consisted of 291 athletes who had competed in Atlanta, Sydney, and Beijing Olympic Games. The relative age effect was examined for the general distribution of athletes by quartile, for each of the individuals, and for male and female athletes. There were no discernable effects of relative age on Olympic Taekwondo athletes.     

THE MORAL MURDERER. A (MORE) EFFECTIVE COUNTEREXAMPLE TO CONSEQUENTIALISM

My aim in this paper is to provide an effective counterexample to consequentialism. I assume that traditional counterexamples, such as Transplant (A doctor should kill one person and transplant her organs to five terminal patients, thereby saving their lives) and Judge (A judge should sentence to death an innocent person if he knows that an outraged mob will otherwise kill many innocent persons), are not effective, for two reasons: first, they make unrealistic assumptions and, second, they do not pass the rule‐consequentialist institutional test. My example (The Moral Murderer), instead, assumes a realistic empirical framework and the relevant action does not undermine basic social institutions. On the contrary, it reinforces them. In The Moral Murderer, Tom (an adult male) is morally allowed to murder a person (preferably a woman) in order to be punished to death.     

Evaluation of the effectiveness of minimum intervention measures on young offenders

The goal of this study was to analyze the recidivism rate in minor offenders to whom a minimum intervention measure was applied after their first felony or misdemeanor, and to determine the variables associated with recidivism. The sample was made up of 154 minors from the province of Santa Cruz of Tenerife (Canary Islands, Spain). The information was collected from the database of the Minors' Court. The recidivism rate depends on the measure imposed, ranging between 14 and 40.6%. The degree of agreement between the Technical Team's proposal and the court decision was 70%. With regard to the variables associated with recidivism, a model was obtained through logistic regression that correctly classified 83.7% of the cases, and was made up of the variables perception of parenting problems, intervention of social services, and social isolation.
