Social and motivational functioning is not critically dependent on feedback of autonomic responses: neuropsychological evidence from patients with pu…
2004
Social, emotional and motivational behaviours are associated with production of automatic bodily responses. Re-representation in the brain through feedback of autonomic and skeletomuscular arousal is proposed to underlie "feeling states". These influence emotional judgments and bias motivational decision-making and guide social interactions. Consistent with this hypothesis, dissocial behaviour and deficits on emotional and motivation tasks are associated with blunted bodily responses in patients with orbitofrontal brain lesions or developmental psychopathy. To determine the critical dependence of social and emotional behaviours on bodily responses mediated by the autonomic nervous system, w…
Mental Toughness Moderates Social Loafing in Cycle Time-Trial Performance
2016
The purpose of this study was to determine if mental toughness moderated the occurrence of social loafing in cycle time-trial performance.Twenty-seven men (Mage = 17.7 years, SD = 0.6) completed the Sport Mental Toughness Questionnaire prior to completing a 1-min cycling trial under 2 conditions: once with individual performance identified, and once in a group with individual performance not identified. Using a median split of the mental toughness index, participants were divided into high and low mental toughness groups. Cycling distance was compared using a 2 (trial) × 2 (high-low mental toughness) analysis of variance. We hypothesized that mentally tough participants would perform equall…
Chronic social defeat-induced social avoidance as a proxy of stress resilience in mice involves conditioned learning
2019
Abstract Chronic social defeat (CSD)-induced social avoidance is considered to model a feature of stress-related mental dysfunction, while its absence has been used as a proxy of resilience in rodents. However, knowledge on the mechanisms shaping CSD-induced individual outcomes remains fragmentary. Fear conditioning has been described as a suitable model in humans for better understanding the pathophysiology of stress related mental disorders. We sought to explore the extent to which conditioned learning is involved in CSD-induced social avoidance. In experiment 1 (social avoidance specificity), C57BL/6 J male mice underwent CSD followed by a modified social interaction test offering the si…
Blaming the Victim: The Effects of Extraversion and Information Disclosure on Guilt Attributions in Cyberbullying
2013
Cyberbullying victims' success in coping with bullying largely depends on schoolmates and other bystanders' social support. However, factors influencing the degree of social support have as yet not been investigated. In this article, the concept of victim blaming is applied to cyberbullying incidents. It is assumed that a cyberbullying victim receives less social support when the victim's behavior is perceived as very overt. It is further assumed that this effect's underlying process is the partial attribution of responsibility for the incident to the victim and not to the bully. The hypotheses are tested with a 2×2 online experiment. In this experiment, varying online self-presentations of…
An aggression machine. II. Interindividual differences in the aggressive defence responses aroused by varying stimulus conditions.
1973
PitkAnen, L. An aggression machine. II. Interindividual differences in the aggressive defence responses aroused by varying stimulus conditions. Scand. J. Psychol., 1973, 14, 65–74.-The subjects, six aggressive and nonaggressive groups of ten 9-year old boys, selected by rating method, were tested with an “aggression machine” (PAM) constructed by the writer. The varying stimulus conditions included two situations of impulsive aggression and six variations of specified attackers. The results showed that (1) the larger part of the variance of the intensity of aggression in the PAM was accounted for by the situational variations than by interindividual differences in coping with thwarting situa…
Drinking motives mediate cultural differences but not gender differences in adolescent alcohol use
2015
Item does not contain fulltext PURPOSE: To test whether differences in alcohol use between boys and girls and between northern and southern/central Europe are mediated by social, enhancement, coping, and conformity motives. METHODS: Cross-sectional school-based surveys were conducted among 33,813 alcohol-using 11-to 19-year-olds from northern Europe (Denmark, Estonia, Finland, Ireland, Poland, Scotland, and Wales) and southern/central Europe (Belgium, Hungary, Italy, Portugal, Slovakia, and Switzerland). RESULTS: Particularly in late adolescence and early adulthood, boys drank more frequently and were more often drunk than girls. Instead of mediation, gender-specific motive paths were found…
Effects of bupropion, alone or coadministered with nicotine, on social behavior in mice
2008
Bupropion, administered alone or combined with nicotine, is presently used to treat nicotine dependence. Despite experimental evidence of the complex behavioral actions of this drug, there have been little data reported about its effects on social behavior. Our main aim was to investigate the effects of acute administration of bupropion, alone or plus nicotine, on social interaction in mice. OF1 group-housed male mice were confronted in a neutral cage with an anosmic opponent during a 10 minutes encounter. Time allocated to body care and digging was reduced by administration of bupropion (40 mg/kg) both when administered alone and with nicotine (1 and 0.5 mg/kg). The lowest dose of bupropio…
Simulated poaching affects global connectivity and efficiency in social networks of African savanna elephants-An exemplar of how human disturbance im…
2022
Selective harvest, such as poaching, impacts group-living animals directly through mortality of individuals with desirable traits, and indirectly by altering the structure of their social networks. Understanding the relationship between disturbance-induced, structural network changes and group performance in wild animals remains an outstanding problem. To address this problem, we evaluated the immediate effect of disturbance on group sociality in African savanna elephants—an example, group-living species threatened by poaching. Drawing on static association data from ten free-ranging groups, we constructed one empirically based, population-wide network and 100 virtual networks; performed a …
Cocaine exposure during adolescence affects anxiety in adult mice.
2006
Psychostimulant drugs such as cocaine have profound and long-lasting neurobiological effects, which may affect anxiety or social behaviors. These actions could be greater when cocaine is administered during a developmental period such as adolescence. The present work attempts to further clarify the long-lasting effects of cocaine administration on mice, examining three major variables: age; pattern of drug administration; and housing conditions. Adolescent (postnatal day 26) or early adult mice (postnatal day 46) were exposed to a daily or binge cocaine administration and 15 days later their behavior was evaluated, the mice being housed either in isolation or in groups during this stage. Af…
A Type A and Type D Combined Personality Typology in Essential Hypertension and Acute Coronary Syndrome Patients: Associations with Demographic, Psyc…
2016
Many studies have focused on Type A and Type D personality types in the context of cardiovascular diseases (CVDs), but nothing is known about how these personality types combine to create new profiles. The present study aimed to develop a typology of Type A and Type D personality in two groups of patients affected by and at risk for coronary disease. The study involved 711 patients: 51.6% with acute coronary syndrome, 48.4% with essential hypertension (mean age = 56.4 years; SD = 9.7 years; 70.7% men). Cluster analysis was applied. External variables, such as socio-demographic, psychological, lifestyle, and clinical parameters, were assessed. Six groups, each with its own unique combined pe…
