La Impulsividad y su Asociación con la Inclinación de la Frente

Avances en embriología, genética o neuroimagen, están ayudando a discernir posibles correlaciones entre estructuras del rostro, cerebro y personalidad. Una conducta que ha sido objeto de numerosas investigaciones es la impulsiva, de la que han surgido distintas conceptualizaciones con cierta controversia etiológica. En el presente trabajo estudiamos si el rostro refleja de manera objetiva el nivel de impulsividad. Para ello, se utilizó en población adulta (N=33), la dimensión Búsqueda de Novedad del Inventario de Temperamento y Carácter-Revisado de Cloninger, la Escala de Impulsividad de Barratt (BIS-11) y la Escala de Impulsividad Estado (EIE). En el rostro se midió el grado de inclinación de la frente hacia atrás, resultando una asociación positiva con las 3 puntuaciones psicométricas. Tres jueces evaluaron visualmente el nivel de inclinación de la frente. Se obtuvo un alto acuerdo entre ellos, así como una alta correlación con la medida objetiva de inclinación. Aunque la muestra es reducida, los datos ofrecen una aproximación al objetivo de estudi

Bizygomatic width and personality traits of the relational field Ancho bizigomático y rasgos de personalidad del campo relacional

The bizygomatic width when compared to the bigonial width (WD) has been proposed as a craniofacial marker of some social and personality traits, such us self-reliance or the ability to express emotions. However, no studies have examined the association between WD and psychopathic traits, as happens with other craniofacial variables such us the facial width-to-height ratio (fWHR). In a sample of 70 adults (male and female) we took measures of the bizygomatic and the bigonial arches. Subjects performed self-assessment tests to evaluate their self-reliance, their alexithymia and emotional expressiveness and their coldheartedness or callous-unemotional. Results showed a significant relationship between WD and self-reliance, emotional expression and alexithymia, and a tendency towards significance with general psychopathic scores. Additionally, we found a modificatory effect of the variables sex and age when analyzing the influence of the WD on the Factor 3-"Coldheartedness" of the Psychopathic Personality Inventory-Revised (PPI-R), where this effect diminished depending on the subject's sex and age. Results suggested that the WD seem to be a good marker to be taken into consideration in further research that examines craniofacial traits and personality traits of the socio-emotional field
