小学四年级儿童简算策略获得的认知过程研究

研究策略获得的过程是了解认知机制的重要途径。本研究采用口语报告和教学实验的结合研究,采用策略意识和策略状况两个维度的评价指标考察,结果表明：策略运用从低到高体现出8级认知序列,策略获得者在策略的掌握过程中有四种认知状态：策略运用初期的倒退状态、策略从不熟练向熟练发展过渡的不稳定状态、策略运用的不彻底状态、有较强的策略意识但缺乏条件化知识的刻板状态。这四种状态反映出,学习者在策略获得过程中策略运用缺陷的常见状况。     

孝意识的时间分析

The reason for the emergence of consciousness of filial piety is that parental care could activate reciprocal filial piety. Parental care and filial piety are two supplementary phenomena caused by the same time consciousness. Phenomenology neglects consciousness of filial piety because it lacks the thinking that sees the fundamental “meaning of time” in the intersection of “past” and “future”. The consciousness of filial piety can only be really constituted by a human being’s personal experience. “Frustrations in personal life” and “breeding of children for oneself” are two occasions for an adult to fight against the separating effect of individualized consciousness and regain awareness of filial piety.

"我思":从笛卡儿到萨特

Cogito, as the first principle of Descartes’ metaphysical system, initiated the modern philosophy of consciousness, becoming both the source and subject of modern Western philosophical discourse. The philosophies of Maine de Biran, Kant, Husserl, Heidegger, Sartre, Merleau-Ponty, and others developed by answering the following questions? Is consciousness substantial or not? Does consciousness require the guarantee of a transcendental subject? Is Cogito epistemological or ontological? Am I a being-for-myself or a being-for-others? Outlining the developmental history of the idea of Cogito from Descartes to Sartre is important for totally comprehending the evolution and development of Western philosophy.     

Building an active citizenry: the role of neighborhood problems, readiness, and capacity for change

Community-building initiatives strive to involve residents as the drivers of the change process, involving them in an array of activities including collective action efforts. Recent evaluations of many of these initiatives, however, suggest that developing the levels of resident involvement needed in such efforts is challenging. This study examines the neighborhood conditions that are related to whether and how much residents become involved in individual activism and collective action efforts. A random-digit-dial phone survey of 460 residents in 7 distressed neighborhoods suggested that while demographic variables were relatively unimportant, resident perceptions of neighborhood readiness (i.e., hope for the future and collective efficacy) and capacity for change (i.e., social ties and neighborhood leadership), and the level of neighborhood problems were strongly related to whether and how much residents were involved in individual and collective action efforts. Moreover, different elements of these neighborhood conditions were more or less important depending on the type and level of resident involvement. For example, while perceptions of neighborhood problems was the strongest predictor of whether an individual became involved at all, perceived strength of neighborhood leadership was the strongest predictor of an individual's level of activity. The implications of these findings for practitioners and scientists are discussed.     

Personal Political Salience: The Role of Personality in Collective Identity and Action

Personal political salience (PPS) is proposed as a personality characteristic that assesses individuals' linkage of political events with their personal identities. Its role in facilitating the development of politicized collective identity and action is examined. In four samples of midlife and activist women, we show that PPS was consistently related both to politicized gender identity and political participation. Further analyses show similar results for PPS, politicized racial identity, and political participation. Politicized gender identity mediated the relationship between PPS and women's rights activism, and politicized racial identity mediated the relationship between PPS and civil rights activism. PPS is demonstrated to independently predict political action and also to provide a personality link between group memberships, politicized collective identity, and political participation.     

On the Correlation between Synchronized Oscillatory Activities and Consciousness

Recent experiments have shown that the amplitudes of cortical gamma band oscillatory activities that occur during anesthesia are often greater than amplitudes of similar activities that occur without anesthesia. This result is apparently at odds with the hypothesis that synchronized oscillatory activities constitute the neural correlate of consciousness. We argue that while synchronization and oscillatory patterning are necessary conditions for consciousness, they are not sufficient. Based on the results of a binocular rivalry study of Fries et al. (1997), we propose that the degrees of oscillatory strength and synchronization of neuronal activities determine the degree of awareness those activities produce. On the other hand, the overal firing rates of neurons in cortical sensory areas are not correlated with the degree of awareness the activities of those neurons produce. The results of the experiment of Fries et al. (1997) appear to conflict with the results of another binocular rivalry experiment, in which monkeys were trained to pull a lever in order to report which stimulus object was being perceived (Leopold & Logothetis, 1996). In the latter experiment, it was demonstrated that the firing rates of neurons in striate cortex did not change during perceptual alterations, while 90% of neurons in inferior and superior temporal cortices changed their firing rate when the perceived image changed. This result led to the conclusion that activities in temporal cortex are correlated with visual awareness, but those in striate cortex are not. We argue that activities in temporal cortex contribute little, if anything, to perceptual awareness, and that their primary function is computational. Thus the correlation between the firing rates of neurons in these areas and the responses of the monkeys is due to the recognition of a particular stimulus object, which in turn is due to the computations made there.     

Spiritual Development: Han F. De Wit's and Stanislav Grof's Differing Approaches

For both Han F. de Wit and Stanislav Grof, spirituality constitutes an essential part of humaneness; a life built on materialism is deemed an impoverished life. For de Wit, spirituality yields courage, compassion, joy, clarity of mind, and consequently wisdom. For Grof, personal spiritual experiences gained during altered states of consciousness are of central interest. After defining spirituality, these views, built on long-term personal experiences of the authors and those of others, are explicated in detail. Both authors describe their respective approaches to spiritual development. In either approach, third-person knowledge and judgments (e.g., on humanness) have to be supplemented by first-person knowledge and judgments arrived at appropriately (e.g., on humaneness).     

Theism, Dualism, and the Scientific Image of Humanity

Recently, some philosophers of religion have suggested that a reduction of the classical image of humanity may jeopardize classical theism. To obstruct reductionism, some theologians have argued for dualism on the basis of the argument of consciousness. In this essay, I argue that even consciousness must be considered a brain-based phenomenon. This does not commit one to reductionism, however. Nonreductive physicalism appears to offer a promising alternative to either dualism or reductionism, without necessarily compromising more traditional views of humanity. I do suggest that a modification of the classical image of God may be inevitable.     

EVOLUTION AND SUBJECTIVITY

Evolutionary theory is becoming an all‐encompassing form of explanation in many branches of philosophy. However, emergence theory uses the concept of self‐organization to support yet alter traditional evolutionary explanation. Biologist Stuart Kauffman suggests that the new science will need to tell stories, not simply as a heuristic device but as part of its fundamental task. This claim is reminiscent of C. S. Peirce's criticism of the doctrine of necessity. Peirce's suggestions reference Hegel, and this essay draws out this Hegelian background, addressing the question of subjectivity and issuing some Hegelian reminders so that such evolutionary and emergent theories will consider the implication of this research program on philosophy of mind. The primary focus is on two post‐Kantian, neo‐Hegelian thinkers in contemporary philosophy who deal with this problem: John McDowell and Robert Brandom.
