Abstract

Using electroencephalographic (EEG) and cardiac measures, the study examined relevant mechanisms that may explain individual differences in self-rated emotion perception (i.e., the propensity of perceiving the emotional states of other persons in everyday life). Healthy women (n = 122) were confronted with film scenes showing the suffering of other people. Functional coupling between prefrontal and posterior cortices, measured by EEG coherences, more strongly decreased in individuals higher on emotion perception. This finding suggests that the propensity to loosen prefrontal inhibitory control on posterior cortical areas involved in basic processes of emotion perception is associated with higher susceptibility to social-emotional information and, therefore, with higher scores on self-rated emotion perception. In addition, higher self-rated perception of other persons' emotions was related to more pronounced cardiac responses to the observation of horrifying events occurring to people in the film which indicate enhanced attention and heightened perceptual processing

Abstract

Resumen Reconocer y denominar expresiones emocionales son habilidades en cuyo estudio existe un creciente interés por parte de la psicología y las neurociencias; trastornos tales como el autismo, la esquizofrenia y la depresión se caracterizan por dificultades en reconocer las emociones ajenas. El hallazgo de diferencias a favor de las mujeres en Percepción Emocional (PE) ha sido replicado transculturalmente por lo que sirve como evidencia de validez. En esta investigación, de diseño instrumental, se construyeron 28 ítems y se pusieron a prueba mediante el modelo de Rasch (MR) en una muestra de población general española (102 varones y 102 mujeres; rango de edad=18-65). El ajuste datos-modelo fue suficiente. Las medidas de las personas muestran que el test resultó fácil (rango = -.60 a 4.14 logits). Se hallaron las diferencias sexuales predichas, d= -.36 (d con corrección de la atenuación= -.50); que ningún ítem mostrase funcionamiento diferencial (DIF) asociado al sexo y que la variable construida tenga propiedades intervalares añade confianza al valor estimado del tamaño del efecto. La construcción de una escala de intervalo en la que se localizan conjuntamente ítems y personas ofrece información cuantitativa y permite detectar patrones inesperados de respuesta que pueden ser de utilidad para el diagnóstico neuropsicológico. Abstract Recognizing and labeling emotion expressions are abilities in whose study psychology and the neurosciences are increasingly interested; disorders such as autism, schizophrenia and depression are characterized by difficulties in recognizing others' emotions. The finding of sex differences favoring women in Emotion Perception (EP) has been replicated cross-culturally, and so it can be used as validity evidence. In this instrumental design study, some 28 items were constructed and tested by means of the Rasch model (RM) in a Spanish community sample (102males and 102 females; age range=18-65). Data-model fit was good enough. Person measures show that the test was easy (range = -.60 to 4.14 logits). Even so, the predicted sex differences favoring women were found, d= -.36 (disattenuated d= -.50). That no item showed sex-related Differential Item Functioning (DIF) and that the constructed variable has interval scale properties add confidence to the effect size estimated value. The construction of an interval scale on which EP items and persons are conjointly represented offers quantitative information and allows the discovery of unexpected response patterns.
