重点中学与普通中学学生非智力因素的比较研究   总被引:8,自引:0,他引:8  
崔丽娟  瞿平 《心理科学》1998,21(1):39-42
本研究分别对重点中学与普通中学初一、初三年级学生的非智力因素状况进行调查,结果表明初一年级学生的非智力因素水平在两类学校之间不存在差异,而初三年级学生的非智力因素水平在两类学校之间存在着显著性差异(P<0.05)。随着年龄的增长,重点中学与普通中学学生的非智力因素水平都有所发展,但重点中学的学生发展得更好。本研究表明学校的教育环境影响着学生非智力因素的发展。  相似文献

初中一,二年级学生的亲子冲突   总被引:24,自引:1,他引:24  
方晓义  董奇 《心理科学》1998,21(2):122-125
本研究选取北京市两所普通中学192名初一和初二学生为被试,通过学生对8个方面亲子冲突的评价,探讨初中生亲子冲突的特点。研究发现,(1)初中生早期的亲子冲突处于较低水平;(2)与母亲的冲突多于与父亲的冲突,女生尤其如此;(3)多数亲子冲突随年级而增加;(4)在多数冲突上,男生与父母的冲突多于女生;(5)亲子冲突最多的三个方面为日常生活安排、学业和家务,而冲突最少的为隐私。  相似文献

The behavior of children diagnosed with attention deficit hyperactivity disorder (ADHD) has been hypothesized to be the result of decreased sensitivity to consequences compared to typical children. The present study examined sensitivity to reinforcement in 2 boys diagnosed with ADHD using the matching law to provide more precise and quantitative measurement of this construct. This experiment also evaluated the effects of methylphenidate (MPH) on sensitivity to reinforcement of children with ADHD. Subjects completed math problems to earn tokens under four different variable-interval (VI) schedules of reinforcement presented in random order under both medicated and nonmedicated conditions. Results showed that, in the medicated condition, the matching functions for both subjects resulted in higher asymptotic values, indicating an overall elevation of behavior rate under these conditions. The variance accounted for by the matching law was also higher under the medicated conditions, suggesting that their behavior more closely tracked the changing rates of reinforcement while taking MPH compared to placebo. Under medicated conditions, the reinforcing efficacy of response-contingent tokens decreased. Results are discussed with respect to quantifying behavioral changes and the extent to which the drug interacts with prevailing contingencies (i.e., schedule values) to influence behavioral variability.  相似文献

Forensic facial professionals have been shown in previous studies to identify people from frontal face images more accurately than untrained participants when given 30 s per face pair. We tested whether this superiority holds in more challenging conditions. Two groups of forensic facial professionals (examiners, reviewers) and untrained participants were tested in three lab-based tasks: other-race face identification, disguised face identification, and face memory. For other-race face identification, on same-race faces, examiners were superior to controls; on different-race identification, examiners and controls performed comparably. Examiners were superior to controls for impersonation disguise, but not consistently superior for evasion disguise. Examiners' performance on the Cambridge Face Memory Test (CFMT+) was marginally better than reviewers and controls. We conclude that under laboratory-style conditions, professional examiners' identification superiority does not generalize completely to other-race and disguised faces. Future work should administer other-race and disguise face identification tests that allow forensic professionals to follow methods and procedures they typically use in casework.  相似文献

Abstract

Our study aimed to analyze movement control strategies using predefined criteria for amplitude and differences in these strategies between children with and without DCD. Children with (n?=?28) and without DCD (n?=?15) were included. A video-observation-tool was used to score the moving body parts during a Wii Fit slalom task over multiple time points. Two-step cluster analysis was used to extract distinct movement strategies. Two different movement strategies were identified that were independently validated by a measure of task performance and a subjective mark of quality of the movement. Initial differences between groups and changes over time toward the more successful strategy were found in both groups, albeit in a different percentage. This study shows that the more efficient movement strategy is seen in the majority of the TD children and only in a small number of children with DCD, even after practice.  相似文献

Face matching is the act of deciding whether two facial images depict the same person or different people. The real-world face-matching task of checking photo IDs typically occurs under conditions of image-size disparity: A small picture is compared with a life-size face. We examined the effect of image-size disparity on face-matching accuracy. In three experiments, subjects were presented with pairs of equivalently or disparately sized images that depicted the same person or different people. Subjects made same/different judgments and, in two experiments, also reported confidence. Difference detection was significantly poorer given disparate (versus equivalent) image size. Confidence was significantly higher when responses were correct versus incorrect. These findings held whether viewing and decision time was unlimited or limited. Our results raise the practical concern that image-size disparity may undermine difference detection in ID checking, while also indicating that people have some insight into the accuracy of their face-matching judgments.  相似文献

The visual acuity of the eyes varies outside the range of normal vision, requiring corrective lenses, but also within the normal range. This study investigated whether both types of variation relate to individual differences in face-identity matching, considering this applied task requires perception of detail. Across two experiments, face-matching accuracy correlated with variation in acuity when this fell outside the normal range of vision and was uncorrected with glasses or contact lenses. In contrast, variation in visual acuity within the normal range did not affect face-matching accuracy, whereas matching accuracy at a given level of acuity could vary substantially. These results indicate that visual acuity is only a problem for occupations performing face-identity matching when below-normal acuity is not diagnosed or adequately corrected. In turn, these findings suggest that variation in acuity within the normal range is not a contributing factor to individual differences in face matching accuracy.  相似文献

IntroductionDominant theories of wayfinding may have underestimated the ease with which adults can learn a route, even with minimal exposure to that route.ObjectivesIn this paper we present three different experiments to provide a comprehensive picture of whether adults can learn complex routes consisting of a number of choicepoints, and if so, what strategies they might be employing to do so.Methodand results We found that adults could learn a 15-junction route after only a single experience of the route (Experiment 1) but that they underestimated how good they would be at learning the 15-junction route (Experiment 2). In Experiment 3, we found that when learning a route made up of “T” shaped junctions, participants relied on a “beacon” strategy based on visual matching.ConclusionsCollectively, these findings suggest that adults can learn complex routes, even with as many as 15 choicepoints, very quickly and without the need for repeated exposure. These findings have implications for theories of wayfinding and call into question the need for repeated exposure.  相似文献
