Is a lack of cerebral hemisphere dominance a risk factor for social ¬タワconflictedness¬タン?: Mixed-handedness in shyness and sociability

چکیده
Recent evidence suggests that a combination of shyness and sociability is associated with distinct behavioral and psychophysiological correlates at rest and in response to social stress and may be a risk factor for developmental psychopathology in children and illicit substance use in adolescents and young adults. Using the Cheek and Buss (1981) measurement model on the relative independence of shyness and sociability as a theoretical platform, we examined whether shyness and sociability were distinguishable on a measure of cerebral hemisphere dominance (i.e., a continuous measure of handedness) in young adults. We found a significant interaction between shyness and sociability on handedness. Undergraduates classified as high shy/high social had a higher degree of mixed-handedness compared with other combinations of shyness and sociability. Findings are discussed in terms of how mixed-handedness may reflect a lack of cerebral lateralization of some psychological processes important to the regulation of social behavior. 2005 Elsevier Ltd.

There are certain well-known relationships between handedness and mode of brain organization. For instance, the large majority of right-handers have speech represented in the left cerebral hemisphere; however, of the left-handed population, about two-thirds have speech represented in the left hemisphere and about one-third in the right. Furthermore, whereas right-handers tend to show a clear-cu...

A number of studies have suggested that shyness and sociability may be orthogonal dimensions of personality, each of which is associated with distinct behavioral and psychophysiological correlates, and that a combination of shyness and sociability may be a risk factor for illicit drug use. We examined whether self-reported shyness, sociability, and sensation seeking measures predicted substance...

Introduction: Based on the previous studies, we know that the hemispheric lateralization defects, increase the probability of psychological disorders. We also know that dominant limb is controlled by dominant hemisphere and limb preference is used as an indicator for hemisphere dominance. In this study we attempted to explore the hemispheric dominance by the use of three limbs (hand, foot...

Numerous studies have suggested that shyness and sociability may be orthogonal personality traits, each of which are associated with distinct behavioural and psychophysiological correlates. Shyness has been linked to a variety of adverse mental health outcomes, and individuals who are high on both shyness and sociability (conflicted subtype) may be particularly at risk. The current study first ...
