A domain-specific hierarchical conceptualization of mathematics achievement can be represented by the standard psychometric model in which a single latent dimension accounts for observed individual differences in scores on the respective subdomains (e.g., quantity). Alternatively, a fully hierarchical conceptualization of achievement can be represented by a nested-factor model in which individual differences in subdomain-specific scores are explained by both general student achievement and specific mathematics achievement. The authors applied both models to study the gender similarity hypothesis, the greater male variability hypothesis, and the masking hypothesis, which predicts that gender differences in general student achievement mask gender differences in both the means and the variability of specific mathematics achievement. Representative data were obtained from 275,369 15-year-old students in 41 countries. The results supported these hypotheses in most countries, demonstrating that a fully hierarchical conceptualization of achievement in terms of the nested-factor model significantly contributes to a better understanding of gender differences in the mean level, variability, and shape of students' achievement profiles. 相似文献

The aim of this study was to specify whether cerebellar lesions cause visuospatial impairments in children. The study sample consisted of 40 children with low‐grade cerebellar astrocytoma, who underwent surgical treatment and 40 healthy controls matched with regard to age and sex. Visuospatial abilities were tested using the spatial WISC‐R subtests (Block Design and Object Assembly), Rey–Osterrieth Complex Figure, Benton Judgment of Line Orientation Test, PEBL Mental Rotation Task, and Benton Visual Retention Test. To exclude general diffuse intellectual dysfunction, the WISC‐R Verbal Intelligence IQ, Performance IQ, and Full‐Scale IQ scores were analysed. Post‐surgical medical consequences were measured with the International Cooperative Ataxia Rating Scale. Compared to controls, the cerebellar group manifested problems with mental rotation of objects, visuospatial organization, planning, and spatial construction processes which could not be explained by medical complications or general intellectual retardation. The intensity of visuospatial syndrome highly depends on cerebellar lesion side. Patients with left‐sided cerebellar lesions display more severe spatial problems than those with right‐sided cerebellar lesions. In conclusion, focal cerebellar lesions in children affect their visuospatial ability. The impairments profile is characterized by deficits in complex spatial processes such as visuospatial organization and mental rotation, requiring reconstruction of visual stimuli using the imagination, while elementary sensory analysis and perception as well as spatial processes requiring direct manipulation of objects are relatively better preserved. This pattern is analogous to the one previously observed in adult population and appears to be typical for cerebellar pathology in general, regardless of age. 相似文献

Research has focused on students’ difficulties understanding phenomena in which agency is distributed across actors whose individual-level behaviors converge to result in collective outcomes. Building on Levy and Wilensky (2008), this study identified features of distributed causality students understand and that may offer affordances for instruction. Students displayed more distributed reasoning than anticipated, used hybrid and flexible reasoning, and reasoned about additive effects of collections of agents and their interactions, even when intent was unaligned. 相似文献

The purpose of this cross-sectional study was to examine the developmental trajectory of creative potentials of Polish students. A total of 1,522 Polish students aged between 7 and 18 from lower and upper primary school, middle school, and high school participated in the study. Creative potential was measured by means of the Test for Creative Thinking-Drawing Production. The findings showed that older students achieved higher scores than the younger ones, drops in mean scores among students aged 13 and 16 were noted, and levelling of scores was found among students aged from 10 to 13, with a slight drop at the age of 13. Moreover, a phenomenon was discovered which was described as a mini plateau, i.e., an emergence of similar mean scores in 2 consecutive age groups. Possible explanations of the results are discussed, including interpretations in the context of the CMC and educational and environmental conditions which act as inhibitors or stimulators of the development of creative abilities. 相似文献

When people synchronize taps with isochronously presented stimuli, taps usually precede the pacing stimuli [negative mean
asynchrony (NMA)]. One explanation of NMA [sensory accumulation model (SAM), Aschersleben in Brain Cogn 48:66–79, 2002] is that more time is needed to generate a central code for kinesthetic-tactile information than for auditory or visual stimuli.
The SAM predicts that raising the intensity of the pacing stimuli shortens the time for their sensory accumulation, thereby
increasing NMA. This prediction was tested by asking participants to synchronize finger force pulses with target isochronous
stimuli with various intensities. In addition, participants performed a simple reaction-time task, for comparison. Higher
intensity led to shorter reaction times. However, intensity manipulation did not affect NMA in the synchronization task. This
finding is not consistent with the predictions based on the SAM. Discrepancies in sensitivity to stimulus intensity between
sensorimotor synchronization and reaction-time tasks point to the involvement of different timing mechanisms in these two
tasks. 相似文献

Self-humanization is defined as the tendency to view oneself as more essentially human than others. Researchers have claimed that people attribute human nature traits more strongly to themselves than to others, but not uniquely human traits. In this article we suggest that such claims are based on the misinterpretation of results. Most studies have not presented mean comparative judgments, making it impossible to determine whether people thought they possessed characteristics less strongly or more strongly than the average person. We found that people (N = 256) in Poland, Italy, and Korea perceived themselves as possessing desirable human nature and uniquely human characteristics more than others, as possessing undesirable uniquely human traits less than others, and as similar to others in terms of undesirable human nature characteristics. It seems that being more human than others means possessing some traits more than others and possessing some traits less than others. 相似文献

Cognitive deficits in depression are mostly apparent in executive functions, especially when integration of information and reasoning is required. In parallel, there are also numerous studies pointing to the frontal alpha band asymmetry as a psychophysiological marker of depression. In this study, we explored the role of frontal alpha asymmetry as a potential factor explaining the cognitive problems accompanying depression. Twenty-six depressed and 26 control participants completed a reasoning task and underwent 5 minutes of electroencephalography recording. In line with the previous studies, depressed people showed difficulties with reasoning but we did not observe the relationship between frontal asymmetry in the alpha band and depression. However, we found that in the depressed group the frontal alpha asymmetry index was characterised by larger variance than in the control group, and it was also a strong predictor of cognitive functioning exclusively in the depressed group. Our results point to the disruption of a psychophysiological balance, reflected in changed frontal alpha asymmetry (into more left-sided frontal asymmetry in the alpha band, reflecting more right-sided cortical activity) as a possible brain correlate of cognitive disturbances present in depressive disorders. 相似文献

This study is an attempt to reconstruct and sum up philosophical interpretations of Stavrogin, the main hero of the classic
Dostoevsky’s novel “The Devils”, given by the outstanding Russian religious thinkers in the twentieth century. The author
emphasizes that, however different can be their philosophical premises, the discussed interpretations of Dostoevsky’s hero
are compatible and complementary. Confronting and, above all, synthesizing different points of view, he tries to grasp the
basic historiosophical, anthropological and religious ideas of Russian renaissance. 相似文献
