Human altruism is a widespread phenomenon that puzzled evolutionary biologists since Darwin. Economic games illustrate human altruism by showing that behavior deviates from economic predictions of profit maximization. A game that most plainly shows this altruistic tendency is the Dictator Game. We hypothesized that human altruistic behavior is to some(More)
Dancing, which is integrally related to music, likely has its origins close to the birth of Homo sapiens, and throughout our history, dancing has been universally practiced in all societies. We hypothesized that there are differences among individuals in aptitude, propensity, and need for dancing that may partially be based on differences in common genetic(More)
Attention deficit hyperactivity disorder (ADHD) is a developmental syndrome expressed along three domains: inattention, hyperactive-impulsive, and combined type. Both environmental and genetic factors contribute to the etiology of this complex disease. In the current investigation, a catechol-O-methyltransferase (COMT) polymorphism that codes for a high(More)
Dopamine transmission is known to play an important role in the reinforcement system of the brain. Studies have identified dopamine system genes whose polymorphic variants have been linked with the intensity of psychological traits reflecting the tendency to form behaviors characterized by impulsivity and the need for additional stimulation. The aim of the(More)
BACKGROUND A key protein in maintaining neuronal integrity throughout the life span is brain-derived neurotrophic factor (BDNF). The BDNF gene is characterized by a functional polymorphism, which has been associated with stress-related disorders such as anxiety-related syndromes and depression, prompting us to examine individual responses by Genotype and(More)
OBJECTIVE In an ongoing molecular genetic study of temperament, participants were genotyped to examine the association of smoking with two polymorphisms of the serotonin transporter gene (SERT): the promoter region, 5-HTTLPR, and an intronic variable-number-of-tandem-repeats region (VNTR). METHOD Full information was available for 330 families, and 244(More)
Increasing evidence suggests that two nonapeptides, arginine vasopressin and oxytocin, shape human social behavior in both nonclinical and clinical subjects. Evidence is discussed that in autism spectrum disorders genetic polymorphisms in the vasopressin-oxytocin pathway, notably the arginine vasopressin receptor 1a (AVPR1a), the oxytocin receptor (OXTR),(More)
showing that patients who developed a greater increase in depressive symptoms during pegIFN-a2b and ribavirin treatment were less likely to show virologic response at the end of the treatment. As Raison et al suggest, a persisting or less responsive virus could cause worse fatigue and depression by inducing inflammation and immune activation. However, it is(More)
A functional polymorphism in the upstream regulatory region of the serotonin transporter gene has been recently reported to be associated with anxiety-related traits assessed by the NEO-PI-R. Individuals both hetero- and homozygous for the short form of a highly repetitive regulatory element in this gene have significantly higher neuroticism scores. We have(More)
Dopamine D4 receptor (DRD4), serotonin transporter promoter regulatory region (5-HTTLPR) and catechol O-methyltransferase (COMT) polymorphisms were examined for association with TPQ personality factors in 455 subjects. Significant interactions were observed by multivariate analysis, (COMT x 5-HTTLPR: Hotelling's Trace = 2.3, P = 0.02) and by subsequent(More)
