Adverse Social Experiences in Adolescent Rats Result in Enduring Effects on Social Competence, Pain Sensitivity and Endocannabinoid Signaling
2016
Abstract: Social affiliation is essential for many species and gains significant importance during adolescence. Disturbances in social affiliation, in particular social rejection experiences during adolescence, affect an individual's well-being and are involved in the emergence of psychiatric disorders. The underlying mechanisms are still unknown, partly because of a lack of valid animal models. By using a novel animal model for social peer rejection, which compromises adolescent rats in their ability to appropriately engage in playful activities, here we report on persistent impairments in social behavior and dysregulations in the endocannabinoid (eCB) system. From postnatal day (pd) 21 to…
Aggressive and nonaggressive rejected students: An analysis of their differences
2006
The present study aimed to analyze differences between aggressive and nonaggressive rejected students in four sets of variables: personal, family, school, and social. Participants in the study were 843 Spanish adolescents ranging in age from 11 to 16 years old, of whom 47% were boys. Results indicated that these two subgroups of rejected students show a different profile. Aggressive rejected students informed of lower levels of family self-esteem, less parental support, higher levels of aggression between their parents at home, and a more offensive parent–child communication in comparison with nonaggressive rejected adolescents. Moreover, aggressive rejected students showed lower levels of …
Propiedades psicométricas de la Escala de Victimización Escolar entre Iguales (VE-I)
2018
<p>La violencia escolar entre iguales tiene graves consecuencias para las víctimas. La victimización puede ser directa, mediante agresiones físicas y verbales, y relacional mediante exclusión y rechazo social. El objetivo de este estudio fue analizar las propiedades psicométricas de la escala de Victimización Escolar entre Iguales (VE-I) que consta de 11 ítems relativos a diferentes formas de victimización. En este estudio participaron 1389 adolescentes (50.45% varones), de entre 11 y 15 años (M = 13.37, DE = 1.23). La estructura de la escala fue analizada mediante análisis factorial exploratorio y análisis factorial confirmatorio, por lo que se utilizaron dos submuestras diferentes.…
Being moved by listening to unfamiliar sad music induces reward‐related hormonal changes in empathic listeners
2021
Many people enjoy sad music, and the appeal for tragedy is widespread among the consumers of film and literature. The underlying mechanisms of such aesthetic experiences are not well understood. We tested whether pleasure induced by sad, unfamiliar instrumental music is explained with a homeostatic or a reward theory, each of which is associated with opposite patterns of changes in the key hormones. Sixty-two women listened to sad music (or nothing) while serum was collected for subsequent measurement of prolactin (PRL) and oxytocin (OT) and stress marker (cortisol and adrenocorticotropic hormone) concentrations. Two groups of participants were recruited on the basis of low and high trait e…
