Human altruism is a widespread phenomenon that puzzled evolutionary biologists since Darwin. Economic games illustrate human by showing behavior deviates from economic predictions of profit maximization. A game most plainly shows this altruistic tendency the Dictator Game. We hypothesized to some extent hardwired and likely candidate may contribute individual differences in arginine vasopressin 1a ( AVPR1a ) receptor mammals such as vole has profound impact on affiliative behaviors. In...
Economic games observe social decision making in the laboratory that involves real money payoffs. Previously we have shown allocation of funds Dictator Game (DG), a paradigm illustrates costly altruistic behavior, is partially determined by promoter-region repeat region variants arginine vasopressin 1a receptor gene (AVPR1a). In current investigation, encoding related oxytocin (OXTR) was tested for association with DG and paradigm, Social Values Orientation (SVO) task.Association (101 male...
Dancing, which is integrally related to music, likely has its origins close the birth of Homo sapiens, and throughout our history, dancing been universally practiced in all societies. We hypothesized that there are differences among individuals aptitude, propensity, need for may partially be based on common genetic polymorphisms. Identifying such lead an understanding neurobiological basis one mankind's most universal appealing behavioral traits—dancing. In current study, 85 performing...
In an ongoing molecular genetic study of temperament, participants were genotyped to examine the association smoking with two polymorphisms serotonin transporter gene (SERT): promoter region, 5-HTTLPR, and intronic variable-number-of-tandem-repeats region (VNTR).Full information was available for 330 families, 244 "ever smokers" identified (54 past smokers, 190 current smokers). The average number cigarettes smoked per day 13.12, mean Fagerstrom Tolerance Questionnaire score 4.79....
Definitions of "full recovery" from anorexia nervosa (AN) vary, and rarely include the cognitive criteria lack body image distortion fear weight gain. We investigated implications including or excluding AN in definition recovery". Current symptomatology personality characteristics associated with were assessed compared 42 behaviorally but not cognitively recovered women, 32 both 253 controls. On all measures included, scores women significantly more anorexic-like than those as well, who...
One hundred and seven healthy volunteers were administered Cloninger's Tridimensional Personality Questionnaire (TPQ), the Differential Attentional Processes Inventory (DAPI), Tellegen Absorption Scale (TAS), Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C). Polymorphisms of catechol O-methyltransferase (COMT), an enzyme involved in dopamine metabolism, assessed. Highly hypnotizable subjects self-reported greater TPQ persistence, absorption, focused attentional abilities. Hierarchical...
Abstract The dopamine D4 receptor ( DRD4 ), a well‐characterized, polymorphic gene, is an attractive candidate for contributing risk to disordered eating and anorexia nervosa (AN). We tested association using UNPHASED 5 loci, 3 promoter region SNPs (C‐521T, C‐616G, A‐809G), the 120 bp tandem duplication exon III repeat, in 202 AN trios 418 control families. Since perfectionism characterizes AN, we these five loci with Child Adolescent Perfectionism Scale (CAPS) groups. Single locus analysis...
Abstract Objective The Eating Disorders Examination–Questionnaire (EDE-Q) is widely used but time-consuming to complete. In recent years, the advantages and disadvantages of several brief versions have therefore been investigated. A seven-item scale (EDE-Q-7) has excellent psychometric properties excludes items on bingeing purging. This study aimed evaluate a thirteen-item (EDE-Q-13) including Method Participants were 1160 (188 [11.4%] males) community volunteers mean age 28.79 ± 9.92. They...
Only recently have studies of electrocortical activity, event-related potentials, and regional cerebral blood flow begun to shed light on the anatomical neurobiological underpinnings hypnosis. Since twin show a significant heritable component for hypnotizability, we were prompted examine role common, functional polymorphism in contributing individual differences hypnotizability. A group 109 subjects (51 male, 59 female) administered three psychological instruments tested high/low enzyme...
Early experiences and childhood perceptions of interparental conflict (IPC) have consistently been shown to detrimental consequences for future psychological adjustment, in particular attachment couple relationships during adolescence adulthood. We hypothesized that 1. IPC would predict anxious avoidant styles, three relational attitudes associated with relationships: sense entitlement, pathological concern, authenticity; 2. Attachment style mediate the associations between these attitudes....
Adult picky eating (PE) can cause distress, malfunction, and malnutrition. The purpose of this study was to examine adult PE, its relationship childhood PE symptoms obsessive-compulsive disorder (OCD), sensory processing disorder, food general disgust, maternal child feeding practices. participants (N = 772; 636 women) self-reported on measures (Adult Picky Eating Questionnaire (APEQ)), (Obsessive-Compulsive Inventory-Revised (OCI-R)), difficulties (Sensory Responsiveness...
Persistence (RD2) is a subscale of the reward dependence trait, one three major personality factors assessed by Tridimensional Personality Questionnaire (TPQ). Subjects with high RD2 scores are characterized as industrious, hard-working, ambitious, perfectionistic. TPQ were examined in 577 normal subjects inventoried for two common genetic polymorphisms, catechol O-methyltransferase (COMT) valine to methionine (val met) amino acid substitution that determines and low enzyme activity,...
Abstract Towards further clarifying the role of dopamine D5 receptor (DRD5) microsatellite polymorphism in etiology ADHD, we used a robust family based strategy to test for association between DRD5 and this disorder. Additionally, neuropsychological mechanism by which allele may confer risk was explored examining relationship genotype scores on continuous performance test. DNA obtained from 164 probands their parents. majority these were administered computerized test, Test Of Variables...
Purpose: We tested the hypothesis that aesthetic athletes (AA) have anorexic-like eating attitudes and behaviors, share personality characteristics such as perfectionism obsessiveness, are at high risk of disorders. Methods: compared symptomatology, variables typical anorexia nervosa, lifetime disorder prevalence across four groups Israeli women: 31 anorexics, 111 AA (mostly dancers), 68 nonaesthetic (NAA), 248 controls. All participants completed self-report measures harm avoidance,...
Abstract. Two markers near the vasopressin receptor (AVPR1A) gene located on chromosome 12q14-15 were tested for linkage to two complex social behaviors in humans: Sibling relationships and self-presentation style. Self-report questionnaires administered 552 same-sex siblings from 248 families. Suggestive was observed between both microsatellites (RS1 RS3) Relationship Questionnaire Conflict scale (RS1: χ 2 = 13.65, LOD 2.96, p .0001; RS3: 14.54, 3.16, .00007) Concern Appropriateness Scale...
