Individuals with high anxiety show heightened neural activation in affective processing regions, including the amygdala and insula. Activations have been shown to be correlated with anxiety severity, but although anxiety is a heterogeneous state, prior studies have not systematically disentangled whether neural activity in affective processing circuitry is uniquely related to specific domains o...

Sensation seeking has been widely studied when investigating individual differences in the propensity for taking risks. However, risk taking can serve many different goals beyond the simple management of physiological arousal. The present study is an investigation of affect self-regulation as a predictor of risk-taking behaviors in high-risk sport. Risk-taking behaviors, negative affectivity, e...

OBJECTIVE Psychological interactions between parents,children and social environment are very important for childhood health. The type of personality and stressful events are probably also cancer risk factors. We investigated personality types A/B and D (negative affectivity and social inhibition) in parents of children with cancer (PCC), as well as social environmental factors, and family / ch...

PURPOSE/OBJECTIVES To explore the association between quality of life (QOL) and type D personality, which is characterized by the traits of negative affectivity and social inhibition, and to further identify impacts of these traits after controlling for biophysical and psychological factors in colorectal cancer survivors. DESIGN Cross-sectional and correlational. SETTING Oncology and surgic...

BACKGROUND It has been suggested that participant withdrawal from studies can bias estimates. However, this is only possible when withdrawers and nonwithdrawers differ in an important way. We tested the hypothesis that withdrawers are more likely than nonwithdrawers to be avoidant and negatively affected. METHODS A total of 1160 participants with inflammatory bowel disease were recruited at d...

Humans have a fundamental need for strong interpersonal bonds, yet individuals differ appreciably in their degree of social integration. That these differences are also substantially heritable has spurred interest in biological mechanisms underlying the quality and quantity of individuals' social relationships. We propose that polymorphic variation in the oxytocin receptor gene (OXTR) associate...

OBJECTIVE To quantify the influence of genes and environment on individual differences in type-D status, and the type-D subcomponents negative affectivity and social inhibition. Type-D personality independently predicts poor prognosis in patients with cardiovascular disease. However, no previous study has determined the heritability of type-D personality. METHODS This study determined type-D ...

Although Obsessive-Compulsive Disorder (OCD) and Depression are classified as separate disorders, the high incidence of co-morbidity and the strong correlations between measures of each has led to debate about the nature of their relationship. Some authors have proposed that OCD is in fact a mood disorder while others have suggested that the two disorders are grounded in negative affectivity. A...

Aims: The present study examined the effects of protracted alcohol withdrawal on affectivity, craving, selective attention and executive functions (EFs) in alcohol-dependent patients.Methods: Selective attention (The D2 Cancellation Test), flexibility (Trail Making Test), inhibition (Stroop Task), decision making (Iowa Gambling Task), craving (Obsessive–Compulsive Drinking Scale) and state affe...

This article addresses the topic: Affectivity and Learning has as an investigation problem: how can negative affectivity affect student learning? The following research questions are: does affective relationship influence How with school community occur? What are main problems of this in relation to affectivity? As a central assumption: impairs students’ learning. objectives analyze whether rel...
