Sensation seeking and impulsivity are personality traits that are correlated with risk for antisocial behavior (ASB). This paper uses two independent samples of twins to (a) test the extent to which sensation seeking and impulsivity statistically mediate genetic influence on ASB, and (b) compare this to genetic influences accounted for by other personality traits. In Sample 1, delinquent behavi...

Temperament and personality traits such as neuroticism and behavioral inhibition are prospective predictors of the onset of depression and anxiety disorders. Exposure to stress is also linked to the development of these disorders, and neuroticism and inhibition may confer or reflect sensitivity to stressors. Several lines of research have documented hyperactivity of the hypothalamic-pituitary-a...

OBJECTIVES Although changes in novelty seeking and harm avoidance have been reported among patients with Parkinson's disease (PD), the findings regarding the neurochemical correlates of such changes are inconsistent. This study was designed to examine the hypothesis that different patterns of motor and neurochemical asymmetry in PD may have contributed to the conflicting results. METHODS Fort...

Parkinson's disease (PD) is, apart from the well-known motor symptoms, also characterized by neuropsychological and emotional disturbances. However, patients also often present with a personality profile of low Novelty Seeking and high Harm Avoidance. This profile can be identified as the disease emerges, which raises the question whether these traits correlate with more fundamental neuropsycho...

Novelty preference or sensation seeking is associated with disorders of addiction and predicts rodent compulsive drug use and adolescent binge drinking in humans. Novelty has also been shown to influence choice in the context of uncertainty and reward processing. Here we introduce a novel or familiar neutral face stimuli and investigate its influence on risk-taking choices in healthy volunteers...

This paper proposes a conceptual framework for creative information seeking drawing upon Weisberg’s argument that creativity exists in everyone, and mapping the creative process described in the holistic model of creativity to the information seeking activities identified in the behavioural model of information seeking. Using scenarios of information seeking behaviour, mappings between the crea...

This research set out to investigate the internet information seeking behavior of older users in New Zealand. The findings show that older internet users are diverse group with a wide range of skills and attitudes but that they do exhibit specific internet behaviors based on their information seeking behavior. A classification of how older New Zealanders use the Internet is presented based on a...

Many research-based models of information seeking behaviour are limited in their ability to describe everyday life information seeking. Such models tend to focus on active information seeking, to the neglect of less-directed practices. Models are often based on studies of scholars or professionals, and many have been developed using a cognitive approach to model building. This article reports o...

With the aim of improving human-centric risk communication, this research in progress paper argues for a social-cognitive perspective focusing on the interaction between laypeople and the information environment. A model is designed to predict laypeople’s environmental risk perception and information seeking behavior. Using data from a national online survey (N=1,032), our research is an effort...
