Vision, Visibility, and Empirical Research. In general, natural scientists use the concept of observation in a liberal way:
they talk of observing electrons, DNA, or distant quasars. Several philosophers of science have recently argued for a similar
use of the concept of observation: they have claimed that the important aspects of scientific research can only be properly
reconstructed in accordance with how this term is actually used in science. With reference to an example from astronomy, I
point out that the proposed generalisation of the concept of observation leads to undesirable consequences. I argue that a
differentiated conceptual framework is required in order to give an adequate account of the varieties of scientific experience.
Thus, the appropriate starting point for distinguishing these various scientific research practices should not be the generalised
scientific conception of observation, but instead distinctly different uses of the term observation drawn from ordinary language.

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

Although past research provided some clues about the relation of language use with mental health, the mediatory functions of personality variables in this relationship have been ignored. This research examined the mediatory role of self‐concept clarity in the relationship between language use perceived by individuals and mental health indicators including anxiety, depression, and alexithymia. Based on the theoretical framework suggested by ?im?ek (2010), two studies sought to test two alternative structural equation models in data from university students in the first study (n = 250) and data from other groups in the second study (n = 331). The first model assumed that the relationship of language use with anxiety, depression, and alexithymia was mediated by self‐concept clarity. The second model tested the mediatory role of both anxiety and self‐concept clarity in this relationship. The results of the first study showed that the second model fitted better to the data than the first. Consistent with the first study, the results of the second study confirmed that the second model produced better goodness of fit statistics than the first model. 相似文献

已有大量研究揭示了近似数量系统与计算流畅性的相关关系, 但缺少对二者关系原因的系统检验与论证。视觉形状知觉假设有别于传统的数量领域特异性解释, 认为对形状的快速知觉是近似数量系统与计算流畅性的共同认知机制, 即视觉形状的快速知觉能力可以解释二者之间的相关关系。近似数量系统和计算流畅性在加工过程中依赖对形状的快速知觉, 二者在加工过程中都涉及了复杂视觉刺激的快速处理。视觉形状知觉假设得到了一系列研究结果的支持, 但局限在视觉形状知觉与二者关系的探讨上, 视觉形状知觉在二者关系中作用的加工机制仍不清楚。未来研究需要结合多种研究方法和技术, 多角度深入探讨视觉形状知觉在二者关系中作用的认知与脑机制, 并将研究结果应用于数学课堂教学和计算困难的干预中。 相似文献

Adorno contends that something of what we think of knowing and rational agency operate in ways that obscure and deform unique, singular presentations by relegating them to survival-driven interests and needs; hence, in accordance with the presumptions of transcendental idealism, we have come to mistake what are, in effect, historically contingent, species-subjective ways of viewing the world for an objective understanding of the world. And further, this interested understanding of the world is deforming in a more radical way than just obscuring what is there for the sake of interested needs and purposes; these instrumental ways of knowing and acting, are broadly self-interested, in the interest of survival, without effective concern for the well-being and worth of others; by becoming generalized and exclusive, hegemonic, by driving out modes of encountering things and persons that support their differences and independence, their needs and interests, these instrumental practices are the deepest cause of the ills of our time. As heightened forms of rational self-interest, self-interest being the drive of reason, transcendental interests suppress the interests of others. Adorno argues that modernist artistic practices perform a critique of the set of assumptions governing idealism by demonstrating how there is a suppressed rational form of human comportment directed towards the making and comprehension of unique sensuous particulars. Art, according to Adorno's ‘Aesthetic Theory’, is a broken off and isolated fragment of human knowing; in its hibernates the rational forms of acting and knowing that have been suppressed in the coming to be of Enlightened modernity. 相似文献

ABSTRACTThree-to-five-year-old French children were asked to add or remove objects to or from linear displays. The hypothesis of a universal tendency to represent increasing number magnitudes from left to right led to predict a majority of manipulations at the right end of the rows, whatever children's hand laterality. Conversely, if numbers are not inherently associated with space, children were expected to favour laterality-consistent manipulations. The results showed a strong tendency to operate on the right end of the rows in right-handers, but no preference in left-handers. These findings suggest that the task elicited a left-to-right oriented representation of magnitudes that counteracted laterality-related responses in left-handed children. The young age of children and the lack of a developmental trend towards right preference weaken the hypothesis of a cultural origin of this oriented representation. The possibility that our results are due to weaker brain lateralisation in left-handers compared to right-handers is addressed in Discussion section. 相似文献

采用康春花、孙小坚和曾平飞(2016)提出的等级反应多水平侧面模型探讨了评分者人数和项目个数对被试能力估计准确性的影响。模拟研究的结果表明:(1)随着项目个数的增加,估计值与真值之间的相关也不断增加;(2)评分者人数和项目个数在平均绝对偏差(MAB)和误差均方根(RMSE)上的主效应均显著,两者间的交互效应也显著;(3)简单效应分析发现,当项目较少时,3个评分者条件下的能力估计准确性最好; 随着项目个数的增加,4个评分者的估计误差迅速下降,且表现变为最好。 相似文献

This article describes an approach for assessing and comparing complex cognition in rhesus monkeys and pigeons by training them in a sequence of synergistic tasks, each yielding a whole function for enhanced comparisons. These species were trained in similar same/different tasks with expanding training sets (8, 16, 32, 64, 128 … 1024 pictures) followed by novel‐stimulus transfer eventually resulting in full abstract‐concept learning. Concept‐learning functions revealed better rhesus transfer throughout and full concept learning at the 128 set, versus pigeons at the 256 set. They were then tested in delayed same/different tasks for proactive interference by inserting occasional tests within trial‐unique sessions where the test stimulus matched a previous sample stimulus (1, 2, 4, 8, 16 trials prior). Proactive‐interference functions revealed time‐based interference for pigeons (1, 10 s delays), but event‐based interference for rhesus (no effect of 1, 10, 20 s delays). They were then tested in list‐memory tasks by expanding the sample to four samples in trial‐unique sessions (minimizing proactive interference). The four‐item, list‐memory functions revealed strong recency memory at short delays, gradually changing to strong primacy memory at long delays over 30 s for rhesus, and 10 s for pigeons. Other species comparisons and future directions are discussed. 相似文献
