Interpersonal Violence and its Association with US Migration Desires and Plans among Youths in Guanajuato, Mexico

This study examined interpersonal physical and sexual violence and its association with desires and plans to migrate to the USA among 500 alternative high school students, aged 14?C17?years, from Guanajuato, Mexico. Two thirds of the youths had ever experienced interpersonal violence, the most common form being physical fights. More youths, and more boys relative to girls, reported wanting to migrate than planning to migrate. Although those who had experienced interpersonal violence were not more likely to want to migrate to the USA, their odds of planning to migrate were 44% greater. Gender did not moderate the effect of interpersonal violence.     

Co-occurrence of non-suicidal self-injury and impulsivity in extreme weight conditions

The aims of the present study were to determine the prevalence of non-suicidal self-injury (NSSI) in different eating disorder (ED) groups and morbid obesity, and to investigate whether NSSI in different ED/obesity groups co-occur with impulsivity. We assessed 535 individuals (365 ED and 170 obese patients) by means of a single item assessing lifetime NSSI and the Barratt Impulsivity Scale, which measures different dimensions of impulsivity. The results showed that 19.1% of the ED patients engaged in at least one act of NSSI during their life-time. NSSI was more prevalent in Bulimia Nervosa, Binge Eating Disorder, Eating Disorder Not Otherwise Specified compared to Anorexia Nervosa, Restrictive type and morbid obesity. Finally, ED/obese patients who engaged in NSSI scored significantly higher on the attentional, motor and non-planning subscales than patients without NSSI. The implications of these findings for the treatment of NSSI in binge/purging ED patients are discussed.     

Developmental dissociation of visual dorsal stream parvo and magnocellular representations and the functional impact of negative retinotopic BOLD responses

Localized neurodevelopmental defects provide an opportunity to study structure–function correlations in the human nervous system. This unique multimodal case report of epileptogenic dysplasia in the visual cortex allowed exploring visual function across distinct pathways in retinotopic regions and the dorsal stream, in relation to fMRI retinotopic mapping and spike triggered BOLD responses.     

Exams? Why worry? Interpreting anxiety as facilitative and stress appraisals

Background and Objectives: The present study examined why people differ in how they appraise the same stressful situation (an approaching exam). Design: We explored whether interpreting anxiety as a facilitative emotion can affect the type of stress appraisal people make. Method: One hundred and three undergraduate students took part in this study, which lasted for 10 days (leading up to an exam). The students completed a daily self-reported evaluation of anxiety, emotional exhaustion, and stress experienced. Results: The findings suggest a process by which a stressful time can be experienced as motivating rather than threatening or emotionally exhausting. For example, interpreting anxiety as facilitative moderated the relationship between anxiety and stress appraisals. When interpreting their anxiety as facilitative, individuals showed a higher tendency to make challenge stress appraisals and a lower tendency to appraising the stressor as a threat. These differences were especially visible with high levels of anxiety. Furthermore, interpreting anxiety as facilitative was negatively associated with emotional exhaustion, but positively associated with the academic performance. Conclusions: These findings suggest an explanation why people differ in how they appraise the same stressor: how people interpret their anxiety may to a large part affect how they appraise difficult events and situations.     

Emotional responses to a negative emotion induction procedure in Borderline Personality Disorder

The aim of this study was to determine if patients with Borderline Personality Disorder (BPD) present higher emotional response than healthy controls in a laboratory setting. Fifty participants (35 patients with BPD and 15 healthy controls) underwent a negative emotion induction procedure (presentation of standardized unpleasant images). Subjective emotional responses were assessed by means of self-reported questionnaires while biological reactivity during the procedure was measured through levels of salivary cortisol (sCORT) and alphaamylase (sAA). Patients with BPD exhibited significant lower cortisol levels and higher sAA levels compared to controls. Self-reported emotional reactivity did not give rise to differences between groups but participants with BPD did present higher levels of negative emotional intensity at baseline and during the entire procedure. The findings do not give support to the emotional hyperreactivity hypothesis in BPD. However, BPD patients presented heightened negative mood intensity at baseline, which should be considered a hallmark of the disorder. Further studies using more BPD-specific emotion inductions are needed to confirm the trends observed in this study.     

Parent – infant psychotherapy,the transition to parenthood and parental narcissism: Implications for treatment

In this article the author discusses some of the indications for short- or long-term parent?–?infant psychotherapeutic interventions in terms of what he defines as ‘problems of parenthood’ and ‘problems of parental narcissism’. Brief parent?–?infant psychotherapeutic interventions are most frequently indicated in the case of the former: more neurotic problems of parenthood where the parents present a manic or counter-depressive type of narcissism. Masochistic problems of parenthood are also susceptible to treatment through brief parent?–?infant interventions, although in such cases treatment may have to be continued in another modality of long-term psychotherapy. More dissociated problems of parental narcissism constitute a contraindication for brief psychotherapeutic parent?–?infant interventions. The persecutory narcissism of these parents contributes to a ‘negative pre-transference’ which creates a major resistance to the therapeutic process.     

Time Course of Tactile Gating in a Reach-to-Grasp and Lift Task

Humans’ sensory systems are bombarded by myriad events every moment of our lives. Thus, it is crucial for sensory systems to choose and process critical sensory events deemed important for a given task and, indeed, those that affect survival. Tactile gating is well known, and defined as a reduced ability to detect and discriminate tactile events before and during movement. Also, different locations of the effector exhibit different magnitudes of sensitivity changes. The authors examined that time course of tactile gating in a reaching and grasping movement to characterize its behavior. Tactile stimulators were attached to the right and left mid-forearms and the right index finger and fifth digit. When participants performed reach-to-grasp and lift targets, tactile acuity decreased at the right forearm before movement onset (F. L. Colino, G. Buckingham, D. T. Cheng, P. van Donkelaar, &; G. Binsted, 2014 Colino, F. L., Buckingham, G., Cheng, D. T., van Donkelaar, P., &; Binsted, G. (2014). Tactile Gating in a reaching and grasping task. Physiology Reports, 2(3), e00267.[Crossref] , [Google Scholar]). However, tactile sensitivity at the right index finger decreased by nearly 20% contrary to expectations. This result reflecting that there may be an additional source acting to reduce inhibition related to tactile gating. Additionally, sensitivity improved as movement end approached. Collectively, the present results indicate that predictive and postdictive mechanisms strongly influence tactile gating.     

Susceptibilidad a la sugestión en función de los factores de personalidad

Resumen

Se presentó a los sujetos un informe estándar sobre su personalidad para estudiar hasta qué punto lo acaptaban como adecuado para describirlos a ellos mismos. Se predecía que el grado de aceptación de estos informes variaría en función de las características de personalidad de los sujetos. De acuerdo con Eysenck (1967), los sujetos con valores máximos en E y N a la vez (NE y CI) serían los menos sugestionables, mientras que los sujetos con valores altos en una dimensión y bajos en la otra (NI y CE) serían los más sugestionables. Los resultados apoyan ligeramente esta hipótesis. No obstante se cuestiona el que las predicciones se deriven realmente del modelo de Eysenk y no sean formulaciones «ad hoc».
