The genetics of sports behaviour : the role of the DRD4 gene in sensation seeking in skiers

Thomson, Cynthia J 11 1900 (has links)
Previous research has shown a large genetic influence over personality traits, especially sensation seeking. One gene thought to influence this behavioural trait is the dopamine-4-receptor gene (DRD4), in which variants have been associated with sensation seeking and novelty seeking in some, but not all studies. The inconsistencies between studies may be due to heterogeneity in both the behaviours and the populations being assessed. Some studies included only males and few studies have a priori analyzed males and females separately. SS has been associated with high-risk sports, including skiing; however, this is the first study to address the possibility that genetics may play a role in individuals’ inclination towards SS in sport. Using the Contextual Sensation Seeking Questionnaire for Skiing (CSSQ-S), developed and validated for this study, and the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), levels of SS in males and females were analyzed in association with the alleles of a polymorphism in the dopamine-4-receptor, -521 C/T (a C or a T at position -521). Behavioural analysis of skiers (N = 200) revealed a significant correlation (r²= .506, p < .001) between skier behaviour (CSSQ-S) and skier personality score (ZKPQ) for sensation seeking. Genotype analysis (N = 74) revealed allele frequencies of .58 C and .42 T and an over-representation of the C allele was found in the population of skiers compared with a general Caucasian population (p < .01). In females, a significant association was found between the homozygous C/C genotype and high levels of contextual skiing SS behaviour (N = 36, p = .006, η² = .2), along with a non-significant trend between ZKPQ impulsive SS scores and the alleles of -521 C/T (p = .086). No association, however, was found in males (N=38, p ZKPQ = .473, p CSSQ-S = .345). This study supports the hypothesis that alleles of the DRD4 -521 C/T polymorphism are associated with context-specific SS behaviours, however only in females. Social pressures may differentially influence male and female sensation-seeking behaviour which may explain the lack of association in males, though this hypothesis requires further investigation.

Renegotiating Authoritative Conventions: Wilkie Collins's Blurring of High and Low in The Law and the Lady, The Moonstone and Armadale

Gullander-Drolet, Louise 16 August 2013 (has links)
This thesis is interested in Wilkie Collins’s blurring of high and low, authoritative and non-authoritative discourses, in The Law and the Lady, The Moonstone and Armadale. It looks at how these novels undermine the legal system, realism, and medicine respectively—three discourses that presumed high levels of authority during the nineteenth century. Collins supplements this undermining of authority by privileging less official approaches to human understanding and behavior. I argue that it is this self-reflexive subversion of Victorian normative values that renders his novels deserving of critical attention and reconsideration within the canon

Gifted underachievement and sensation seeking

Laird, Amanda J. January 1998 (has links)
The purpose of this study was to identify a relationship between sensation seeking and underachievement. Archival data of seventy seven students of the Indiana Academy were collected. It was hypothesized that scores on the Sensation Seeking Scale would negatively correlate with grade point average. It was also hypothesized that Sensation Seeking Scale scores would be associated with incidents of academic probation, behavioral problems, and withdrawal from the Indiana Academy. A weak yet significant negative correlation was found between Total Sensation Seeking scores and grade point average. A slightly stronger negative correlation was found between the Disinhibition subscale of the Sensation Seeking Scale and grade point average. Total Sensation Seeking scores were associated with incidents of behavioral problems, but were not associated with incidents of academic probation or withdrawal from the Indiana Academy. Disinhibition subscale scores were associated with incidents of behavioral problems and withdrawal from the Indiana Academy. / Department of Counseling Psychology and Guidance Services
