BACKGROUND: Temperament and character dimensions of personality remain largely unexplored in young adults exhibiting binge drinking patterns. Moreover, the available studies do not consider gender differences, and dismiss possible personality heterogeneity among binge drinkers. In the present study, we aimed to compare temperament and character dimensions between young binge drinkers and age- and sex-matched social drinkers. We further applied cluster analysis to investigate the potential heterogeneity of personality patterns among binge drinking college students...

Touch is one of the first senses to develop and one of the earliest modalities for infant-caregiver communication. While studies have explored the benefits of infant touch in terms of physical health and growth, the effects of social touch on infant behavior are relatively unexplored. Here, we investigated the influence of neonatal handling on a variety of domains, including memory, novelty seeking, and social interest, in infant monkeys (Macaca mulatta; n=48) from 2 to 12 weeks of age. Neonates were randomly assigned to receive extra holding, with or without accompanying face-to-face interactions...

Background and aims The main aim of this study was to analyze and describe the clinical characteristics and shared personality traits in different impulsivity-compulsivity spectrum disorders: substance use disorders (SUD), gambling disorder (GD), and bulimia nervosa (BN). The specific aims were to compare personality differences among individuals with pure SUD, BN with and without SUD, and GD with and without SUD. In addition, we assessed the differential predictive capacity of clinical and personality variables in relation to diagnostic subtype...

OBJECTIVE: This study aimed to examine the association between novelty seeking (NS) and antisocial behaviours (age 18-35). METHOD: A New Zealand general population birth cohort was studied from 1977 to 2012. Sample sizes ranged from n = 962 (age 35) to n = 1025 (age 18). NS was measured at age 16 using the Tridimensional Personality Questionnaire. Perpetration of antisocial behaviours was ascertained by self-report at ages 18, 21, 25, 30 and 35. Generalized estimating equation models investigated the association between NS and antisocial behaviours net of individual factors and correlates of NS before age 16 and alcohol and substance use disorders at age 18-35...

INTRODUCTION: One of the most common reasons individuals do not seek mental health treatment is a preference to manage emotional concerns on their own. Self-management refers to the strategies that individuals use on their own (i.e., without professional guidance) to manage symptoms. Little research has examined self-management for anxiety despite its potential utility as the first step in a stepped care approach to primary care. The objectives of this study were to describe patients' anxiety self-management strategies, identify which types were perceived to be effective, and explore potential correlates...

Gambling disorder is associated to an increased impulsivity, a high level of novelty-seeking and a dysregulation of the forebrain neurotransmission systems. However, the neurobiological mechanisms of this addictive disorder are not fully understood and no valid pharmacological approach has yet been approved. The present study aimed to investigate the effect of 5-HT7 receptor (5-HT7 R) stimulation with a brain penetrant and selective agonist, LP-211 (0.25 and 0.50 mg/kg i.p.) during post-experience consolidation, i) acutely in a novelty-preference test (Exp...

Novelty preference (NP) is an evolutionarily conserved, essential survival mechanism often dysregulated in neuropsychiatric disorders. NP is mediated by a motivational dopamine signal that increases in response to novel stimuli, thereby driving exploration. However, the mechanism by which once-novel stimuli transition to familiar stimuli is unknown. Here we describe a neuroanatomical substrate for familiarity signaling, the interpeduncular nucleus (IPN) of the midbrain, which is activated as novel stimuli become familiar with multiple exposures...

The Roman high- (RHA-I) and low-avoidance (RLA-I) rat strains are bi-directionally bred for their good versus non-acquisition of two-way active avoidance, respectively. They have recently been re-derived through embryo transfer (ET) to Sprague-Dawley females to generate specific pathogen free (SPF) RHA-I/RLA-I rats. Offspring were phenotyped at generations 1 (G1, born from Sprague-Dawley females), 3 and 5 (G3 and G5, born from RHA-I and RLA-I from G2-G4, respectively), and compared with generation 60 from our non-SPF colony...

The observation that children's activity level (AL) differs between novel and familiar situations is well established. What influences individual differences in how AL is different across these situations is less well understood. Drawing on animal literature, which links rats' AL when 1st placed in a novel setting with novelty seeking phenotypes, and child temperament literature, which links AL, novelty response, and shyness, we hypothesized that shyness would be an important component of children's AL in a novel situation...

WHAT IS KNOWN: Drug addiction is a novelty-seeking personality trait that is associated with the candidate genes OPRD1 (opioid delta receptors), OPRK1 (opioid kappa receptors) and PDYN (prodynorphin). However, associations between single nucleotide polymorphisms (SNPs) rs1042114 (80G>T) of the OPRD1 gene, rs702764 (843 A>G) of the OPRK1 gene, and rs910080 (3' UTR _743T>C), rs1997794 (5' UTR -381A>G) and rs1022563 (3' UTR) of the PDYN gene and novelty seeking remain controversial as reported results have not been reproducible...

BACKGROUND: Subthalamic stimulation improves the motor and neuropsychiatric symptoms of Parkinson's disease. However, the impact of this treatment on impulse control and personality is the subject of heavy debate. The objective of this study was to investigate personality changes after subthalamic stimulation. METHODS: Using Cloninger's biosocial model, we assessed personality in 73 Parkinson's disease patients before and 12 months after subthalamic stimulation accompanied by a drastic reduction in dopaminergic medication...

Intrinsic motivation is the inherent tendency to seek out novelty and challenge, to explore and investigate, and to stretch and extend one's capacities. When people imagine performing intrinsically motivating tasks, they show heightened anterior insular cortex (AIC) activity. To fully explain the neural system of intrinsic motivation, however, requires assessing neural activity while people actually perform intrinsically motivating tasks (i.e., while answering curiosity-inducing questions or solving competence-enabling anagrams)...

BACKGROUND: Suicide and mood disorders (especially major depressive disorder (MDD) and bipolar affective disorder (BD)) represent a significant global health burden. Major depressive disorder and bipolar affective disorder have been associated with increased risk for suicide. Some specific suicide risk factors might be found in underlying individual personality traits. Specific personality features may predispose an individual to mood disorders (MDD or BD) hence increased suicide risk...

Zonisamide (ZNS) is an effective drug for not only motor symptoms but also non-motor symptoms in Parkinson's disease. However, the actions of ZNS as an anti-Parkinsonian drug are not well understood. To clarify the actions of ZNS in vivo, we administered ZNS to mice and examined the effects on neurotransmitter metabolism and behaviors, focusing on motor and non-motor symptoms. Administration of ZNS decreased dopamine (DA) turnover in various brain regions, including the striatum. In behavioral tests, ZNS enhanced locomotor activity and novelty seeking in the open field test, light-dark transition test, and the social interaction test...

Mild traumatic brain injury (mTBI) caused by exposure to high explosives has been called the "signature injury" of the wars in Iraq and Afghanistan. There is a wide array of chronic neurological and behavioral symptoms associated with blast-induced mTBI. However, the underlying mechanisms are not well understood. Here we used a battlefield-relevant mouse model of blast-induced mTBI and in vivo fast-scan cyclic voltammetry (FSCV) to investigate whether the mesolimbic dopamine system contributes to the mechanisms underlying blast-induced behavioral dysfunction...

Social familiarization is a process of gaining knowledge that results from direct or indirect participation in social events. Cooperative exchanges are thought to be conditional upon familiarity with others. Indeed, individuals seem to prefer to engage with those that have previously interacted with them, which are more accurate predictors of reward than novel partners. On the other hand, highly social animals do seek novelty. Truth is that the physiological bases underlying how familiarity and novelty may affect cooperative decision-making are still rather obscure...
