Affiliative stimuli as primers to prosocial predispositions

Affiliative stimuli are pleasant and highly biologically relevant. Affiliative cues are thought to elicit a prosocial predisposition. Here affiliative and neutral pictures were exposed prior to a reaction time task which consisted in responding to a visual target. Half the participants responded with finger-flexion, a movement frequently involved in prosocial activities. The other half responded with finger extension, a less prosocially compatible movement. Results showed that under the exposure to affiliative pictures, as compared to neutral ones, participants who used finger flexion were faster, while those using finger extension were slower. Performance benefits to the task, when flexing the finger, together with performance costs, when extending it, indicate the relevance of movement compatibility to the context. These findings put forward a possible link between affiliative primers and motor preparation to facilitate a repertoire of movements related to prosocial predispositions including finger flexion.     

The Lexical Stroop Sort (LSS) picture-word task: a computerized task for assessing the relationship between language and executive functioning in school-aged children

The relationship between language development and executive function (EF) in children is not well understood. The Lexical Stroop Sort (LSS) task is a computerized EF task created for the purpose of examining the relationship between school-aged children’s oral language development and EF. To validate this new measure, a diverse sample of school-aged children completed standardized oral language assessments, the LSS task, and the widely used Dimensional Change Card Sort (DCCS; Zelazo, 2006) task. Both EF tasks require children to sort stimuli into categories based on predetermined rules. While the DCCS largely relies on visual stimuli, the LSS employs children’s phonological loop to access their semantic knowledge base. Accuracy and reaction times were recorded for both tasks. Children’s scores on the LSS task were correlated with their scores on the DCCS task, and a similar pattern of relationships emerged between children’s vocabulary and the two EF tasks, thus providing convergent validity for the LSS. However, children’s phonological awareness was associated with their scores on the LSS, but not with those on the DCCS. In addition, a mediation model was used to elucidate the predictive relationship between phonological awareness and children’s performance on the LSS task, with children’s vocabulary fully mediating this relationship. The use of this newly created and validated LSS task with different populations, such as preschoolers and bilinguals, is also discussed.     

Repetition priming within and between languages in verb generation: evidence for shared verb concepts

Although translation equivalents for concrete nouns are known to have shared core conceptual representations in bilingual memory (Francis, 1999), the status of translation-equivalent verbs has not been systematically tested. Three repetition-priming experiments using a verb generation task were used to determine whether verbs have shared representations across languages and to identify the processes facilitated in repeated verb generation. In Experiment 1 fluent Spanish-English bilingual speakers exhibited repetition priming both within and between languages, but between-language priming was weaker. In Experiment 2 performance of non-bilingual English and Spanish speakers was equivalent to that of bilingual speakers responding in their dominant language. Experiment 3 used manipulations meant to isolate noun comprehension, verb concept selection, and verb production. The between-language priming in Experiments 1 and 3 indicates that verb concepts are shared across languages and that verb concept selection exhibits facilitation. Experiment 3 showed that the greater within-language priming was due primarily to facilitation of verb production processes.     

A modular,computer-controlled system for olfactory stimulation in the MRI environment

Although the cerebral networks involved in sensory perception are of general interest in neuroscience, registration of the effects of olfactory stimulation, especially in a magnetic resonance imaging (MRI) environment, presents particular problems and constraints. This article presents details of a reliable and portable system for olfactory stimulation that is modular in design and based on microcontroller technology. It has the following characteristics: (1)?It is under software control; (2)?the presentation of olfactory stimulation can be synchronized with respiration; (3)?it can be manually controlled; and (4)?it is fully compatible with an MRI environment. The principle underlying this system is to direct an odor to the subject’s nostrils by switching airflow to different odor diffusers. The characteristics of this system were established using (1)?ultraviolet (UV) spectroscopy, to measure its response time, and (2)?gas chromatography, to measure the repeatability of odor presentation in terms of gas concentration. A response time of 200?± 25 ms was obtained for the system, and the standard deviations of the gas concentration delivered during stimulation ranged from 1.5% to 22%, depending on the odor, the airflow, and the dilution of the odor used. Since it is portable, controlled by software, and reliable, on the basis of the results we obtained, this system will lend itself to a wide range of applications in olfactory neuroscience.     

Problematic eating behaviors and nutritional status in 7 to 12 year-old Chilean children

Overweight and obesity are medical conditions that require a multidisciplinary analysis of their causes and treatment. In Chile a sustained increase in the presence of obesity and excess weight has been observed in children. However, the amount and the dynamics of the aforementioned problematic eating behaviours in Chilean children are unknown. The aim of this study was to assess the relationship between restrained, external, and emotional eating, and variations in body mass index (BMI) in Chilean children. Consequently, 453 children from 7 to 12 years of age responded to the Children's Dutch Eating Behaviour Questionnaire, Spanish version. In addition, their anthropometric data were obtained. A positive association was found between restrained eating and BMI, and a negative correlation between external eating and BMI. Emotional eating demonstrated a modest inverse relationship with BMI. A significant interaction between problematic behaviour and nutritional status (normal-weight, overweight, obese) was revealed. Restrained eating was characteristic of obese children whereas external eating of normal-weight children. These results suggest that problematic eating behaviours and their relationship with body weight are similar to those described in studies in Europe.     

Challenges in treating patients with psychosomatic disorders: some patterns of resistance

The treatment of people suffering from psychosomatic disorders poses important clinical challenges to psychoanalytic practice, including early abandonment, difficulties in engagement and superficial involvement in the treatment. The lack of systematic research on the subject suggests that a better understanding of the resistances and dynamics involved in such episodes is needed. Using supervision group to study treatments and inspired by action-research paradigm, this paper presents the results of an 18-month mixed-method qualitative clinical research on treating 22 cases. Thematic analysis revealed a frequent pattern of resistance to experience emotions that presented in two states: failure of repression (thin-skin) and massive repression (thick-skin). Narcissistic dynamics in the therapeutic relationship taking the form of ‘resistance to transference’ and a tendency to action were evident in both presentations. Symmetric and complementary counter-transference reactions, which compromised treatment, were also identified. Some technical implications are highlighted, such as the need to focus in the recovery of the patient's actual emotional experience and to understand such experience in the context of the ‘here and now’ of the therapeutic encounter. These findings suggest the need for a flexible approach to therapeutic work that moves between an ‘intrapsychic’ and a ‘relational’ focus.

Translation and validation of the Spanish version of the "Echelle de Satisfaction des Besoins Psychologiques" in the sports context

The aim of the present research was to translate and to analyze the psychometric properties of the Spanish version of the Satisfaction of Psychological Needs Scale, using a sample of 284 athletes (204 male and 78 female). Results of the confirmatory factor analysis confirmed the correlated three-factor structure of the scale. Furthermore, the results showed evidence of convergence validity with the Basic Psychological Needs in Exercise Scale. The predictive validity was tested using a structural equation model in which task orientation climate predicted the three basic psychological needs and these, in turn, intrinsic motivation. Likewise, we documented evidence of reliability, analyzed as internal consistency and temporal stability. Results partially support the use of the Spanish version of the scale in sports.     

Women’s physical attractiveness and short-term mating strategies

The current study examined the relationship between women’s physical attractiveness – as rated by themselves and a set of third-party raters – and their mating strategy and sexual experience. Male (N = 105) and female (N = 113) undergraduates rated the attractiveness of face and body photographs of 93 female undergraduates. Attractiveness ratings – particularly bodily attractiveness ratings – were significantly related to women’s mating psychology and behavior. More attractive women reported more sexual experience and a less restricted sociosexual orientation. In addition, some traits better predicted women’s perception of their overall attractiveness, and this pattern was further linked to mating strategy: more sociosexually unrestricted women showed a stronger relationship between bodily traits (i.e., body mass index) and overall attractiveness than less sociosexually unrestricted women. Discussion focuses on the findings that a woman’s mating strategy is linked to both her self-perceived and objective measures of attractiveness, particularly bodily attractiveness.     

The family therapist as a change agent: Using principles and strategies of organization development in family therapy

Abstract

Families are compared to work organizations from a systems perspective, establishing parallels in needs for change and growth. The theoretical underpinnings of Organization Development (O.D.) are reviewed and discussed in light of their use in conceptualizing family therapy. From this systems viewpoint, the consultant role, systems diagnosis and a variety of O.D. interventions are proposed to the family therapist.
