本研究采用注意瞬脱实验范式探讨了语义信息在数量表征中的作用。结果发现:(1)在双任务方式中,字母辨认任务对大数(5及以上)的辨认产生干扰,但不影响小数(4及以下)的辨认绩效;(2)数量表征在视野上出现差异性,表现为在小数辨认时,左侧视野呈现绩效高于右侧;大数辨认正好相反,即右侧视野呈现高于左侧。结果表明,语义信息在表征小数和大数中的作用不同:小数的表征无需语言参与;而大数则更多地涉及语义信息,可能需语音回路中无声复述机制的参与。 相似文献

Tokachi sub‐prefecture in Hokkaido is one of the most famous dairy and crop farming regions in Japan. It is known that Tokachi is faced with various difficult problems such as soil degradation, water contamination and unpleasant odours because of the excessive use of chemical fertilizers and inappropriate treatment of livestock excretion. In this paper, we focus on Shihoro town where agricultural outputs are relatively large in Tokachi, and propose collaborative circulating farming with collective operations between arable and cattle farmers. Under the assumption that the decision‐maker in this problem is a representative of a farming organization who hopes for sustainable agricultural development and values the intentions of local residents including arable and cattle farmers in this region, we employ multi‐attribute utility theory in order to evaluate multiple alternatives of the farming management problem.

Abstract The dismantling of apartheid and the postapartheid dispensation had far-reaching implications for all the citizens of South Africa. In an urban sample of White Afrikaans-speaking South Africans (Afrikaners) in postapartheid South Africa, the authors investigated perceptions of threat to ethnic identity, as well as correlates of those perceptions. The respondents experienced threat on 2 levels: The 1st was distinctive continuity, the concern that their ethnic group would not continue as a distinctive group in society. The 2nd was the evaluative dimension of ethnic identity (i.e., well-being), the concern that group membership would no longer contribute to positive self-esteem. The respondents experienced greater threat on the 2nd level, reflecting predominantly negative experiences as White Afrikaans-speaking persons in postapartheid South Africa. A high threat perception on the 2nd level was associated with (a) a perception of other groups' negative evaluations of their ethnic group, (b) negative attitudes toward political changes, and (c) perceptions of illegitimacy and instability of the postapartheid political system. The respondents who felt that Afrikaners would not continue as a distinctive group in society had a more positive attitude toward the sociopolitical changes, did not show strong ethnic identification, and had a negative collective self-esteem. They were also politically more liberal. Those findings are discussed in relation to theoretical expectations. 相似文献

Thinking about the abstract concept power may automatically activate the spatial up-down image schema (powerful up; powerless down) and consequently direct spatial attention to the image schema-congruent location. Participants indicated whether a word represented a powerful or powerless person (e.g. ‘king’ or ‘servant’). Following each decision, they identified a target at the top or bottom of the visual field. In Experiment 1 participants identified the target faster when their spatial position was congruent with the perceived power of the preceding word than when it was incongruent. In Experiment 2 ERPs showed a higher N1 amplitude for congruent spatial positions. These results support the view that attention is driven to the image schema congruent location of a power word. Thus, power is partially understood in terms of vertical space, which demonstrates that abstract concepts are grounded in sensory-motor processing. 相似文献

How people process and represent magnitude has often been studied using number comparison tasks. From the results of these tasks, a comparison distance effect (CDE) is generated, showing that it is easier to discriminate two numbers that are numerically further apart (e.g., 2 and 8) compared with numerically closer numbers (e.g., 6 and 8). However, it has been suggested that the CDE reflects decisional processes rather than magnitude representation. In this study, therefore, we investigated the development of symbolic and nonsymbolic number processes in kindergartners and first, second, and sixth graders using the priming paradigm. This task has been shown to measure magnitude and not decisional processes. Our findings revealed that a priming distance effect (PDE) is already present in kindergartners and that it remains stable across development. This suggests that formal schooling does not affect magnitude representation. No differences were found between the symbolic and nonsymbolic PDE, indicating that both notations are processed with comparable precision. Finally, a poorer performance on a standardized mathematics test seemed to be associated with a smaller PDE for both notations, possibly suggesting that children with lower mathematics scores have a less precise coding of magnitude. This supports the defective number module hypothesis, which assumes an impairment of number sense. 相似文献

IntroductionStudies have shown the importance of psychosocial risks for physical and mental health particularly in the medical sector and among hospital workers.ObjectiveThe main goal of our study is to measure the magnitude of the six dimensions of the psychosocial work environment in a French hospital. The second goal is to highlight from the six dimensions, which are the most important ones for the hospital workers in order to propose specific actions of improvement of the well-being at work and prevention of social risks.MethodOur sample is composed of 1139 hospital workers. (1) A 24-item scale was created, based on the six dimensions identified by the DARES study. This scale allows measuring the degree of psychosocial risk and of well-being at work. (2) Social representations are measured by a free association task based on the target expression: well-being at work in the hospital. (3) Participants also answered an open-ended question, on how to improve well-being at work in the hospital; answers were analyzed by a hierarchical classification.ResultsFour of the six dimensions extracted from the factorial analysis are equal to those identified by the DARES’ report: Work demand, Emotional demands, Relationships at work and Job insecurity. Quantitative analyses show that, for hospital workers, the level of risk is the highest on the first two. The social representation of well-being at work in the hospital, and the discourse analysis indicate that the dimension which is the most important for the hospital workers is Relationships at work.ConclusionIn this study, the use of both quantitative and qualitative assessments allows having some elements to analyze the quality of working conditions in the hospital. Moreover, reducing the level of psychosocial risk has a positive effect on workers’ satisfaction, well-being and health. 相似文献

The second person is often set in contrast to the first person. And there is a contrast. It does not reside in a difference of what is thought as I from what is thought as you. For that is not different. The contrast is that of monadic and dyadic predication, action and transaction. It is the contrast, not of I and You, but of I and I–You. The second person does not add a You to an I. It divides the I and makes it a relation. We consider, first, the form of predication that is common to first- and second-person thought. Then, we define the second person as a species of this form of thought. Last, we find the source and condition of this form of thought in a thought of this very form. This thought, being the source of its own form, is one of which one cannot be conscious from outside it. It is a last word, or, better, a first word.1 相似文献

Young infants’ successful performance on false belief tasks has led several researchers to argue that there may be a core knowledge system for representing the beliefs of other agents, emerging early in human development and constraining automatic belief processing into adulthood. One way to investigate this purported core belief representation system is to examine whether non-human primates share such a system. Although non-human primates have historically performed poorly on false belief tasks that require executive function capacities, little work has explored how primates perform on more automatic measures of belief processing. To get at this issue, we modified Kovács et al. (2010)’s test of automatic belief representation to examine whether one non-human primate species—the rhesus macaque (Macaca mulatta)—is automatically influenced by another agent’s beliefs when tracking an object’s location. Monkeys saw an event in which a human agent watched an apple move back and forth between two boxes and an outcome in which one box was revealed to be empty. By occluding segments of the apple’s movement from either the monkey or the agent, we manipulated both the monkeys’ belief (true or false) and agent’s belief (true or false) about the final location of the apple. We found that monkeys looked longer at events that violated their own beliefs than at events that were consistent with their beliefs. In contrast to human infants, however, monkeys’ expectations were not influenced by another agent’s beliefs, suggesting that belief representation may be an aspect of core knowledge unique to humans. 相似文献
