Background Research suggests that individuals with different attachment patterns process social information differently, especially in terms of facial emotion recognition. However, few studies have explored social information processes in adolescents. This study examined the behavioral and ERP correlates of emotional processing in adolescents with different attachment orientations (insecure attachment group and secure attachment group; IAG and SAG, respectively). This study also explored the association of these correlates to individual neuropsychological profiles. Methodology/Principal Findings We used a modified version of the dual valence task (DVT), in which participants classify stimuli (faces and words) according to emotional valence (positive or negative). Results showed that the IAG performed significantly worse than SAG on tests of executive function (EF attention, processing speed, visuospatial abilities and cognitive flexibility). In the behavioral DVT, the IAG presented lower performance and accuracy. The IAG also exhibited slower RTs for stimuli with negative valence. Compared to the SAG, the IAG showed a negative bias for faces; a larger P1 and attenuated N170 component over the right hemisphere was observed. A negative bias was also observed in the IAG for word stimuli, which was demonstrated by comparing the N170 amplitude of the IAG with the valence of the SAG. Finally, the amplitude of the N170 elicited by the facial stimuli correlated with EF in both groups (and negative valence with EF in the IAG). Conclusions/Significance Our results suggest that individuals with different attachment patterns process key emotional information and corresponding EF differently. This is evidenced by an early modulation of ERP components’ amplitudes, which are correlated with behavioral and neuropsychological effects. In brief, attachments patterns appear to impact multiple domains, such as emotional processing and EFs.

This study examines performance of schizophrenia patients, unaffected relatives and controls in social cognition, cognitive and psychiatric scales looking for possible markers of vulnerability in schizophrenia. Performance of schizophrenia patients from multiplex families, first-degree relatives, and matched controls was compared and, subsequently, discriminant analysis method was used for identifying the best predictors for group membership. By using Multigroup Discriminant Analyses on the three groups, the best predictors were PANSS, Premorbid Adjustment Scale, Faux Pas test, and a face/emotion categorizing task. This model obtained 82% correct global classification, suggesting that the combination of psychiatric scales and neuropsychological/social cognition tesks are the best approach for characterizing this disease. Although preliminary, our results suggest that social cognition tasks are robust markers of schizophrenia family impairments, and that combining clinical, social and neuropsychological measures is the best approach to asses patients and relatives vulnerability.

Low agreement between self-reports and parent reports of the behavioral adjustment of adolescents has been widely documented in the literature. However, it has been little studied in connection with adoptees. In the current research, the magnitude of agreement between reports of adolescents’ behavioral problems given by the adolescents themselves and their parents and the direction of the possible discrepancies between these reports were studied. A comparison was made between adopted and nonadopted adolescent–parent dyads. The research questions were tested on a sample of 294 adolescent–parent pairs (189 adoptees and 105 controls) from Belgium, Romania, Chile, Switzerland, Italy, and the Netherlands. Correlation analyses together with Fisher R to Z comparisons between countries and between adopted and nonadopted dyads and Repeated Measures Analyses revealed that both the magnitude of agreement and the direction of the discrepancies in internalizing and externalizing behavioral ratings between informants, that is, parents and their adolescent, did not depend on whether the adolescents were adopted or not. Compared with their parents, both adopted and control adolescents reported problems more frequently. Some variations in the magnitude of agreement were found between countries. An interaction effect between gender and informant indicated that discrepancies for internalizing behavior were higher in parent–adolescent daughter pairs than in parent–adolescent son pairs.

Este articulo es una revision teorica de los postulados de Peter Fonagy respecto a los Trastornos de Personalidad Borderline (TPB) y su propuesta de abordaje a traves de la psicoterapia basada en la mentalizacion. A partir de la revision se concluye que el modelo planteado para comprender el desarrollo de TPB y los lineamientos para realizar intervenciones psicoterapeuticas, resultan en gran medida un aporte al manejo de estos pacientes. Ya que el mismo ha mostrado empiricamente ser efectivo en la disminucion de riesgo suicida y conductas de autoagresion; siendo estos los sintomas de mayor severidad del trastorno
