In Korea, two number systems are in simultaneous use. One is somewhat irregular (like the English language number system), and the other regular (similar to the Chinese number system). This natural experiment allows a direct test of the hypothesis that structural regularity of the number system facilitates the acquisition of counting. Korean children initially suffer from their numerical ‘bilingualism’: they find it difficult to learn two counting systems at the same time. Yet, after this initial difficulty, they soon master the generative rules which are transparent in the regular system. The cognitive advantage provided by the regular number system then combines with other factors, like intensive teaching and parental pressure, to produce school achievement in mathematics superior to US children's. 相似文献

Ulrich (1987), exploring the shapes of psychometric functions obtained in the ternary-response paradigm, indicated several inconsistencies between observed and predicted relationships providing evidence against most popular models of temporal-order judgment. In this paper, a new model is presented. It assumes that there are two mechanisms involved in the order discrimination task: one is responsible for the recognition of whether or not the stimuli are successive, and the second is able to determine their order. The model was tested using Allan's (1975a, 1975b) and Ulrich's (1987) data; the model predictions were found to be consistent with the experimental results. 相似文献

The relative effect of each informational dimension in an information integration task is a joint function of its weight and the range of values over which it is varied. A method is developed for separating these two factors. Weights obtained by this method were compared across variations of stimulus range. Subjects rated the performance of students on the basis of midterm exam scores and final exam scores. For some subjects, the range of scores on the final exam was twice that on the midterm and the reverse was true for other subjects. An averaging model was shown to describe the results, and weights did not differ for different stimulus ranges. This was true for each of two instructional conditions: one in which a particular weighting strategy was prescribed and one in which there was no prescribed weighting. Students who were instructed to use a 2∶1 weighting were found to assign more than twice as much weight to the final as to the midterm. 相似文献

The editors of the JRE solicited short essays on the COVID-19 pandemic from a group of scholars of religious ethics that reflected on how the field might help them make sense of the complex religious, cultural, ethical, and political implications of the pandemic, and on how the pandemic might shape the future of religious ethics. 相似文献

Acculturation,stress, and depressive symptoms among Korean immigrants in the United States 总被引:2,自引:0,他引:2
A sample of 157 Korean immigrants responded to measures of acculturation level, stress from acculturation, and depressive symptoms. The authors hypothesized that adaptive acculturation would depend on assimilation regarding social interactions and the host culture's language as well as on retention of a core identity, including values and traditions of the culture of origin. Consistent with the mediation hypothesis, acculturation, based on a factor representing language use and social relationships, was related to lower acculturative stress and, in turn, lower depression. However, there was no direct support for the integrative, or bicultural, strategy of acculturation. Stress did not mediate the effect of a 2nd acculturation factor, identity and tradition-based acculturation. Rather, this measure of acculturation was directly related to higher depression (i.e., immigrants reporting abandonment of Korean identity, traditions, and values scored higher for depression). 相似文献

Olivopontocerebellar atrophy (OPCA) is a still debated condition, of which motor disruption is the most common feature. A high incidence of associated mood disorders may exist, but there are few studies on concomitant cognitive impairment. Our aim was to assess whether there is reading and writing disruption in olivopontocerebellar atrophy (OPCA). 6 patients were administered different reading and writing tasks. Scores were then compared to those obtained by healthy volunteers. There was an evident impairment in reading and writing execution in our patients compared to those of the control group. On the contrary, no difference could be found in abstraction, problem-solving, and memory tasks. We discuss the results, debating the role of the cerebellum in the conscious process of cognition or in ocular movement control (necessary for reading and writing fluidity and effective execution) and in the dynamic activation of all the cerebral cortex mediated by the diffuse projection to the reticular system. 相似文献

Many theories have proposed that visual working memory plays an important role in visual search. In contrast, by showing that
a nonspatial working memory load did not interfere with search efficiency, Woodman, Vogel, and Luck (2001) recently proposed
that the role of working memory in visual search is insignificant. However, the visual search process may interfere with spatial
working memory. In the present study, a visual search task was performed concurrently with either a spatial working memory
task (Experiment 1) or a nonspatial working memory task (Experiment 2). We found that the visual search process interfered
with a spatial working memory load, but not with a nonspatial working memory load. These results suggest that there is a distinction
between spatial and nonspatial working memory in terms of interactions with visual search tasks. These results imply that
the visual search process and spatial working memory storage require the same limited-capacity mechanisms. 相似文献

We previously reported that a total methanolic extract of the underground part of Angelica gigas Nakai (Umbelliferae) (here-in-after abbreviated AG) significantly inhibited acetylcholinesterase (AChE) activity. We characterized 12 coumarin derivatives including both decursin and decursinol from extracts of AG. In this study, we evaluated the anti-amnestic activity of decursin, a major coumarin constituent isolated from AG, in vivo using ICR mice with amnesia induced by scopolamine (1 mg/kg body weight, s.c.). Decursin, when administered to mice at 1 and 5 mg/kg body weight i.p., significantly ameliorated scopolamine-induced amnesia as measured in both the passive avoidance test and the Morris water maze test. Moreover, decursin significantly inhibited AChE activity by 34% in the hippocampus of treated mice. These results indicate that decursin may exert anti-amnestic activity in vivo through inhibition of AChE activity in the hippocampus. 相似文献

The purpose of the present study was to explore the relationships between three predictor variables (attitude toward school, parent-child communication, and school commitment action) and the criterion variable (parent involvement) in a representative sample and to examine if these relationships were consistent across three groups (English speaking Caucasian family, English speaking Latino family, and Spanish speaking Latino families). Using a national database (N = 9.841), multi-group SEM analyses were conducted to investigate the relationship between three predictor variables and the criterion variable in three family groups. While all three predictor variables significantly predicted parent involvement in English speaking Caucasian and Latino families, only two variables (parent-child communication and school commitment actions), significantly predicted parent involvement in Spanish speaking Latino families. The results of this study suggest that when administrators, teachers and counselors in school strive to share specific school-related information with Latino families, Spanish speaking families are more likely to become involved with schools. 相似文献
