The effect of phenobarbitone (phenobarbital), predominantly a central depressant, on kinaesthetic after-effect was examined. The subjects were selected after a preliminary testing with the Maudsley Personality Inventory. They were classified into two groups: extraverts and introverts. The drug was used at different dose levels. A 2 × 4 randomized block design was replicated ten times. The study supports the following conclusions: (a) the extraverted subjects show larger kinaesthetic after-effect than introverted subjects under placebo condition; (b) phenobarbitone has no effect on kinaesthetic after-effects in extraverted subjects except in small doses (30 mg) which reduce the size of the effect; (c) the drug in larger doses (60 mg and 100 rng) produces a significant increasing effect in the introverted group. 相似文献

The present study attempts to examine how people perceive non-conforming behaviour and what do they infer about subjects who demonstrate non-conformity. Interviews were conducted to determine the operational definition and perception about non-conformity. Analysis of the interviews revealed that non-conformity is attributed to not abiding by the rules that have been defined or laid out by an authority in a particular context. Scenario-based experiments were conducted, and the obtained data were analysed to reach a conclusion regarding observers’ perception about non-conforming individuals in a collectivist culture. The results showed that non-conforming behaviour leads to a negative inference about status and competence. Also, we found that the attractiveness of non-conforming individuals does not lessen the negative inferences derived by the observers in a collectivist culture. The findings can be extended to devise several communication and signalling strategies to influence the mass behaviour in a collectivist culture, like India. The study provides us insights about achieving social objectives as well as driving behavioural change in a collectivist context. 相似文献

We question the widespread assumption that linguistic theory should guide the formulation of mechanistic accounts of human language processing. We develop a pseudo-linguistic theory for the domain of linguistic stress, based on observation of the learning behavior of a perceptron exposed to a variety of stress patterns. There are significant similarities between our analysis of perception stress learning and metrical phonology, the linguistic theory of human stress. Both approaches attempt to identify salient characteristics of the stress systems under examination without reference to the workings of the underlying processor. Our theory and computer simulations exhibit some strikingly suggestive correspondences with metrical theory. We show, however, that our high-level pseudo-linguistic account bears no causal relation to processing in the perception, and provides little insight into the nature of this processing. Because of the persuasive similarities between the nature of our theory and linguistic theorizing, we suggest that linguistic theory may be in much the same position. Contrary to the usual assumption, it may not provide useful guidance in attempts to identify processing mechanisms underlying human language. 相似文献

Recently, scientific and popular press articles have begun to represent sex as a health-promoting activity. A number of scientific studies have identified possible health benefits of sexual activity, including increased lifespan and decreased risk of certain types of cancers. These scientific findings have been widely reported on in the popular press. This "sex for health" discourse claims that sexual activity leads to quantifiable physical and mental health benefits in areas not directly related to sexuality. Analyzing this discourse provides an opportunity to better understand both broader health promotion discourses and current norms and anxieties about sexuality. In this article, I place this "sex for health" discourse within the context of broader health promotion discourses and within the context of a number of historical and contemporary discourses connecting health and sexuality. I argue that although the "sex for health" discourse may serve to de-stigmatize sexual activity for some, it may also increase pressure on others to be sexually active and may further pathologize sexual "dysfunction." In addition, these representations often serve to further privilege a normative form of sexual behavior - coitus in the context of a monogamous heterosexual partnership - at the expense of non-normative sexual desires, identities, and practices. 相似文献

The present research examined the relationship between endogenous glucocorticoids, navigational strategies in a virtual navigation task, and performance on standard neuropsychological assessments of memory. Healthy young adult participants (N = 66, mean age: 21.7) were tested on the 4 on 8 virtual maze (4/8 VM) and standard neuropsychological tests such as the Rey-Osterrieth Complex Figure (RO) and the Rey Auditory Verbal Learning Task (RAVLT), which measure episodic memory. The 4/8 VM differentiates between navigational strategies, where participants either use a hippocampal-dependent spatial strategy by building relationships between landmarks, or a caudate nucleus-dependent stimulus–response strategy by automatizing a pattern of open and closed arms to learn the location of objects within the maze. Degree of stress was assessed by administering the Perceived Stress Scale (PSS) questionnaire. Cortisol samples were taken on two consecutive days upon waking, 30 min after waking, at 11 am, 4 pm, and 9 pm. There was a significant difference in basal levels of cortisol between spatial and response learners. Interestingly, response learners had significantly lower cortisol levels throughout the day. The two groups did not differ in terms of perceived stress as measured with the PSS questionnaire. Moreover, there was no significant correlation between PSS scores and salivary cortisol levels, indicating that the higher cortisol levels in the spatial group were not associated with greater perceived stress. In addition, participants who spontaneously used a spatial strategy performed significantly better on the RAVLT and RO. These data indicate that the cortisol levels in the spatial group may be optimal in terms of episodic memory performance whereas the cortisol levels in the response group may be associated with poorer memory. These results are suggestive of an inverted U-shaped curve describing the effects of basal levels of circulating cortisol on memory in young adults. 相似文献

There are pragmatic benefits to trait-consistent mood states, especially when people are evaluating new objects within the environment (M. Tamir, M. D. Robinson, & G. L. Clore, 2002). The present studies, involving both naturally occurring (Studies 1 and 2) and manipulated (Study 3) mood states, demonstrated such trait-consistent interactions within the context of neuroticism and negative mood states. Individuals high in neuroticism were faster to make evaluations when in a negative mood state like sadness. By contrast, individuals low in neuroticism were faster to make evaluations when in a neutral mood state. The present studies demonstrate that although negative mood states are hedonically unpleasant, they can be beneficial in some ways for individuals high in neuroticism. 相似文献
