Inverse reference in subtraction performance: an analysis from arithmetic word problems

Studies of elementary calculation have shown that adults solve basic subtraction problems faster with problems presented in addition format (e.g., 6 ± =?13) than in standard subtraction format (e.g., 13 - 6?=?). Therefore, it is considered that adults solve subtraction problems by reference to the inverse operation (e.g., for 13 - 6?=?7, "I know that 13 is 6?+?7") because presenting the subtraction problem in addition format does not require the mental rearrangement of the problem elements into the addition format. In two experiments, we examine whether adults' use of addition to solve subtractions is modulated by the arrangement of minuend and subtrahend, regardless of format. To this end, we used arithmetic word problems since single-digit problems in subtraction format would not allow the subtrahend to appear before the minuend. In Experiment 1, subtractions were presented by arranging minuend and subtrahend according to previous research. In Experiment 2, operands were reversed. The overall results showed that participants benefited from word problems where the subtrahend appears before the minuend, including subtractions in standard subtraction format. These findings add to a growing body of literature that emphasizes the role of inverse reference in adults' performance on subtractions.     

Borderline personality traits in nonclinical young adults

The main purpose of this study was to explore the dimensionality of the borderline personality disorder in nonclinical young adults by means of the Borderline Personality Questionnaire (BPQ; Poreh et al., 2006). We also studied the phenotypic expression of the borderline personality traits as a function of participants' gender and age, and the relationship between BPQ subscales and measures of depressive symptoms, anxiety, stress, hallucinatory predisposition, and paranoid ideation. The sample comprised 809 young adults, 562 (69.5%) were women, with a mean age of 20.2 years (SD = 2.9). The results indicate that the BPQ self-report has adequate psychometric properties. The levels of internal consistency for the BPQ subscales ranged between .78 and .93. Analysis of the internal structure of the BPQ subscales yielded a one-dimensional solution. In contrast, second-order principal components analysis at the item level yielded a five-dimensional solution. Likewise, statistically significant differences in the mean scores of the borderline personality traits as a function of participants' gender and age were found. The BPQ subscales correlated significantly with measures of depression, anxiety, stress, paranoid ideation, and hallucinatory predisposition. These results help to improve our understanding of the dimensional structure of the borderline personality in the general population. Future research should continue to identify participants who are at risk for the development of borderline personality disorder and facilitating the development of early detection and prevention programs.     

The use of dreams in the clinical context: convergencies and divergencies: an interdisciplinary proposal

This paper aims to define some unexpected convergences and foreseeable divergences regarding the conceptualization of dreams and their use as a research tool, specifically in clinical practice with non-neurotic patients. It includes a concise review of different lines of thought on the vicissitudes of dreams throughout the history of psychoanalysis: from their initial conception up to their use to examine transference and relational aspects in the context of a psychoanalytic process. The idea of the merely evacuative function of dreams from patients in certain diagnostic categories is discussed and compared with that of their potential communicative value. Lastly, the essay sets forth an interdisciplinary semiotic-pragmatic approach to the function of dreams and their clinical and technical use in the context of the intersubjective dynamic field. Based on the hypothesis that dreams related in the session are communicative signs, this proposal argues their significance as a symbolic matrix that generates processes of psychic semiosis. To do so, it combines certain lines of psychoanalytic thought with ideas coming from C. S. Peirce's analytic semiotics. Clinical material is included to illustrate this viewpoint.     

Body weight increase in expectant males and helpers of cotton-top tamarin (Saguinus oedipus): a symptom of the Couvade syndrome?

In the cooperative breeding system of cotton-top tamarin (TCB; Saguinus oedipus) males gain weight during the last months of pregnancy of their partners as a way to cope with energy costs of reproduction. This phenomenon was described only in humans as a symptom of . As after infants' birth, TCB male and female helpers lose weight, the same as fathers do, it might be expected that previously, they also gain weight. In 8 groups of TCB, we explored body weight changes of the three categories of individuals, in periods of six months, under three different reproductive conditions: control (no pregnancy and without offspring), pregnancy (pregnancy and without offspring), and raising (with offspring). We found that across pregnancy, TCBs increase their weight in the last trimester of that period while across breeding TCBs reduce their weight in the first trimester. Expectant males and also helpers could be preparing during pregnancy in relation to the weight losses they experience when raising their young.     

Crime prevention: more evidence-based analysis

This paper introduces a new section of Psicothema dedicated to the evidence-based approach to crime prevention. Along with an original sexual-offender-treatment programme implemented in Spain, this section presents four systematic reviews of important subjects in the criminological arena, such as sexual offender treatment, the well-known programme, the effectiveness of custodial versus non-custodial sanctions in reoffending and the fight against terrorism. We also highlight some of the focal points that scientists, practitioners and governments should take into account in order to support this evidence-based viewpoint of crime prevention.     

Justice Perceptions as Predictors of Customer Satisfaction: The Impact of Distributive,Procedural, and Interactional Justice1

This article attempts to extend prior research by testing the effects of justice components (distributive, procedural, and interactional) on customer satisfaction beyond the expectancy disconfirmation paradigm. To this end, two separate field survey studies were conducted. A total of 568 customers were surveyed in 38 hotels and 40 restaurants. The results showed that distributive justice was critical in predicting customer satisfaction, while the influence of procedural and interactional justice was secondary. Justice concepts were also robust against the simultaneous inclusion of disconfirmation and performance in the satisfaction equation. The article concludes with theoretical and managerial implications, as well as opportunities for future research.     

Social cognitive predictors of well-being in African college students

Lent and Brown's (2006, 2008) social cognitive model of work well-being was tested in two samples of African college students, one from Angola (N = 241) and one from Mozambique (N = 425). Participants completed domain-specific measures of academic self-efficacy, environmental support, goal progress, and satisfaction, along with measures of global positive affect and life satisfaction. Path analyses indicated that the model fit the data well overall, both in the full sample and in separate sub-samples by country and gender. Contrary to expectations, however, self-efficacy predicted academic satisfaction only indirectly, via goal progress; and goal progress predicted life satisfaction only indirectly, via academic satisfaction. The predictors accounted for substantial portions of the variance in both academic domain satisfaction and life satisfaction. Implications for research and practice involving the social cognitive model are considered.     

Social Identity and Social Exchange: Identification, Support, and Withdrawal From the Job

Integrating insights from the social exchange perspective and the social identity perspective, we propose that evaluations of support received from the organization and its representatives and organizational identification interact to predict withdrawal from the job. The relationship of support with withdrawal is proposed to be weaker the more strongly employees identify with the organization. This prediction was confirmed in 2 samples focusing on different operationalizations of support and withdrawal. Study 1 explored the interaction between organizational support and organizational identification in predicting turnover intention; Study 2 investigated the link between supervisor support and organizational identification and absenteeism. The present study thus yields evidence that may lay the groundwork for further integration of social exchange and social identity analyses of organizational behavior.     

Resonance and radical embodiment

One big challenge faced by cognitive science is the development of a unified theory that integrates disparate scales of analysis of cognitive phenomena. In this paper, I offer a unified framework that provides a way to integrate neural and behavioral scales of analysis of cognitive phenomena—typically addressed by neuroscience and experimental psychology, respectively. The framework is based on the concept of resonance originated in ecological psychology and aims to be the foundation for a unified theory for radical embodiment; that is, a unified theory for that dissident part of cognitive science that shares a methodological commitment to dynamic systems theory and remains skeptical about the adequacy of mechanism and representationalism as the guiding ideas in the field. In the course of my presentation, I analyze different issues regarding the requirements and constraints unification poses to radical embodiment.
