Two archival studies examined the impact of people's appearance on the status and type of civilian and military jobs they hold. Study 1 found that, although appearance was not related to job status, taller men had higher incomes. Additionally, appearance was significantly related to the type of jobs people held. Attractive women and tall men held jobs requiring traits more consistent with the attractiveness halo, while babyfaced women and short men held jobs more consistent with the babyface stereotype. These effects remained after controlling for job-relevant personality and educational variables, suggesting an unjustified bias toward people with certain appearances. Study 2 found that heavier men had lower job status, as reflected in military rank attainment. However, this relationship was eliminated when controlling for intelligence and dependability. Also, babyfaced men achieved higher status through being marginally more likely to win a military award. This unexpected effect was attributed to the contrast between heroic actions and the babyface stereotype. Finally, appearance affected the type of military experience men had. Heavier men were more likely to be in situations involving gunfire or casualties. These studies make an important contribution by extending laboratory findings to the real world, exploring the effects of appearance on job type as well as status, and providing evidence that appearance effects are not solely due to covariation with bona fide job qualifications. 相似文献

This paper presents, discusses and evaluates empirical studies concerned with Christian prayer. These studies are classified within four main areas. The first area concerns what is known about the practice of prayer from empirical surveys and demonstrates that a much higher proportion of people pray privately than attend public places of worship. The second area concerns what is known about changing patterns of prayer during childhood and adolescence and argues that these changes need to be interpreted within the context of both developmental and social psychology. The third area concerns the subjective effects of prayer, beginning with Galton's early observations concerning the comparative longevity of the clergy (who are regarded as praying people) and including more recent studies of the psychological correlates of self-reported prayer, like personal well-being and purpose in life. It is concluded that, while such studies may demonstrate the beneficial nature of prayer, they cannot demonstrate the causal efficacy of prayer. The fourth area concerns the objective effects of prayer, beginning with Galton's early observations concerning the absence of comparative longevity among royalty (who are regarded as prayed for people) and including more recent studies of the growth correlates of prayer for pot plants. It is concluded that such studies currently provide contradictory evidence. It is recommended that further research in the field needs both to observe the strict criteria of objective empirical research and to be alert to theological nuances regarding the actual claims made for the efficacy of prayer within the community of believers. 相似文献

Responses to an object may be slower or less accurate if that object shares attributes with a recently ignored object(negative priming). Some studies have found negative priming only if the probe trial required selection against a distractor stimulus. In the present experiment, subjects responded to the location of a target (O), ignoring a distractor (X) if it appeared in another location. Reaction time was slower to probe targets that appeared in the same location as the prime distractor, regardless of whether or not the probe target was accompanied by a distractor. 相似文献

The World-Wide Web provides an inviting opportunity to reach large numbers of people, both as an audience for psychoacoustical discussions and demonstrations and as subjects for psychoacoustical experiments. Such use of the Web poses a unique set of challenges. We present the methodologies used to prepare a multimedia primer in auditory perception at McGill University. As well as instructional material, this primer includes acoustical experiments conducted over the Web. We discuss the response and experiences with this site in general and in a particular class situation at Hanover College. 相似文献

Ten subjects served as their own controls in two conditions of continuous, centrifugally produced hypergravity (+2 Gz) and a 1-G control condition. Before and after exposure, open-loop measures were obtained of (1) motor control, (2) visual localization, and (3) hand-eye coordination. During exposure in the visual feedback/hypergravity condition, subjects received terminal visual error-corrective feedback from their target pointing, and in the no-visual feedback/hypergravity condition they pointed open loop. As expected, the motor control measures for both experimental conditions revealed very short lived underreaching (the muscle-loading effect) at the outset of hypergravity and an equally transient negative aftereffect on returning to 1 G. The substantial (approximately 17°) initial elevator illusion experienced in both hypergravity conditions declined over the course of the exposure period, whether or not visual feedback was provided. This effect was tentatively attributed to habituation of the otoliths. Visual feedback produced a smaller additional decrement and a postexposure negative aftereffect, possible evidence for visual recalibration. Surprisingly, the target-pointing error made during hypergravity in the no-visual-feedback condition was substantially less than that predicted by subjects’ elevator illusion. This finding calls into question the neural outflow model as a complete explanation of this illusion. 相似文献

Considerable scientific evidence demonstrates the reduction in risk for neural tube defects (NTDs) associated with maternal preconceptional folic acid supplementation. The National Society of Genetic Counselors (NSGC) endorses the U.S. Public Health Service recommendations for folic acid supplementation at the 0.4 mg level for women in the general population and at the 4.0 mg level for women at high or increased risk for NTD pregnancies for at least 4 weeks prior to active pursuit of conception. We encourage targeted educational efforts and surveillance to assess results of this dietary supplementation. The NSGC further urges the Food and Drug Administration to fortify staple foodstuffs with folic acid for a population-based approach to minimize the number of NTD births. 相似文献

Previous experiments have shown that overshoot rate in a linear positioning task is determined by the distance of the target from the boundary of the task in the direction of movement. Present experiments have served to specify distance more precisely as being relative rather than absolute, and as proximal rather than distal, and to show that the position of the boundary depends on the movements demanded by the task and not the visual and proprioceptive limits of the display. The operational boundary may be regarded as a cognitive construct by reference to which subjects locate targets. 相似文献
