Educational Success in High-Risk Settings: Contributions of the Chicago Longitudinal Study 总被引:1,自引:0,他引:1
I provide an overview of the Chicago Longitudinal Study. This prospective study traces the educational and social success of a large sample of low-income children (over 90% of whom are African American) from high-poverty neighborhoods in the Chicago Public Schools. In 1985–1986, the sample participated in the Child–Parent Centers and other early childhood programs. The four studies reported in this special issue highlight the contributions of school mobility, parent involvement, educational expectations, and other family and school experiences in preventing learning problems and promoting educational success. 相似文献

Pluripotent human stem cell research may offer new treatments for hundreds of diseases, but opponents of this research argue that such therapy comes attached to a Faustian bargain: cures at the cost of the destruction of many frozen embryos. The National Bioethics Advisory Commission (NBAC), government officials, and many scholars of bioethics, including, in these pages, John Robertson, have not offered an adequate response to ethical objections to stem cell research. Instead of examining the ethical issues involved in sacrificing human embryos for the goal of curing fatal and disabling diseases, they seek to either dismiss the moral concerns of those with objections or to find an "accomodation" with those opposed to stem cell research. An ethical argument can be made that it is justifiable to modify or destroy certain human embryos in the pursuit of cures for dread and lethal diseases. Until this argument is made, the case for stem cell research will rest on political foundations rather than on the ethical foundations that the funding of stem cell research requires. 相似文献

Action explanations like 'I am heading to the ferry because the bridge is closed,' are supposed to require restatement: 'I am . . . because I believe the bridge is closed,' because (i) the objective claim may be false though the intended explanation is correct, and (ii) because objective circumstances have to be cognitively mediated if they are to bear on action. This supposition is rejected here. Restatements cannot withdraw the objective claim without withdrawing the explanation. In the context of reason-giving, belief statements do not function as assertions about the inner life. The fact that belief statements may be true though the belief itself is false creates the illusion of distinctive subject matters. The illusion is exploited by conceptions of belief positing stored representations. Even if there were such representations, retrieved for the sake of expressing previously acquired beliefs, the expression of belief must endorse p and cannot merely advert to the existence and content of a representation. The reverse of the standard philosophical view about restatement is actually correct. Wherever an agent correctly adduces a belief that an objective circumstance obtains in explaining his action, a de-psychologizing restatement that merely makes the objective claim must be ascribable to the agent. 相似文献

Abstract— Automatic processes are characterized as being rapid, as requiring little attentional effort, and as obligatory (once initialed, the activity cannot be inhibited or controlled). In contrast, controlled processes are slower, require attention, and are non-obligatory. This distinction appears in the Stroop effect the interference that appears when a person tries to name the color of the ink in which a word is printed when the word spells the name of a different color. This effect has historically been attributed to an automatic reading of the color name interfering with the slower, less automatic, naming of the ink color (MacLeod, 1991, Stroop, 1935). In this report, we describe a patient with focal brain atrophy whose speed of reading was no faster than his speed of naming colors, but who still showed the classic Stroop effect. This finding critically challenges the traditional identification of automaticity with processing speed. 相似文献

Brian Garrett constructs cases satisfying Andy Hamilton's definition of weak q -memory. This does not establish that a peculiar kind of memory is at least conceptually coherent. Any 'apparent memory experiences' that satisfy the definition turn out not to involve remembering anything at all. This conclusion follows if we accept, as both Hamilton and Garrett do, a variety of first-person authority according to which memory judgements may be false, but not on the ground that someone other than the remembering subject had the remembered experience. Garrett's brain-bisection illustration sounds convincing, but only because we retain the idea that the subjects created by implanting a hemisphere each in two different bodies are entitled to say that they remember experiences before the surgery in the ordinary sense. To that extent the illustration presents a case of ordinary memory, not q -memory. 相似文献

Explanations of the cause of the Challenger disaster by the Presidential Commission and by communication scholars are flawed. These explanations are characterized by a common tendency to emphasize the technical and procedural aspects of organizational life at the expense of the cognitive and ethical. Rightly construed, the Challenger disaster illustrates both the need for a revived art of rhetoric and the importance of putting in place the political and social conditions that make this art efficacious in furthering cognitive understanding and ethical conduct. 相似文献

In the past several years, there has been an acceleration in the publication of cognitive research on the interplay between linguistic and pictorial/spatial information. To report on and encourage this sort of research, we organized a symposium at the 1991 meeting of the Midwestern Psychological Association. The articles in this special section ofMemory & Cognition are based on the work presented at the symposium. In this introduction, we offer a suggestion forwhy the integration of linguistic and spatial information is not only a possibility, but a requirement for effective communication. Our suggestion follows the linguistic analysis of the closed-class elements that convey spatial relations, the prepositions (Talmy, 1983). The structure of language provides but a small set of prepositions to encode the vast number of spatial relations that we can perceive. Thus, to understand a situation that a speaker or a writer is conveying, the listener or reader must combine linguistic information with (perhaps metric) spatial information derived from pictures, the environment, or memory. 相似文献

The present study was designed to examine the effects of social stimulation on the joint attention behavior of 20 autistic children under 6 years of age, 20 receptive language-matched Down syndrome children, and 20 receptive language matched-normally-developing infants. Children's social and non-social engagement states were measured during two experimental play sessions and during free play with parent. For all groups, joint attention was increased when adult play behavior closely followed and was contingent on the behavior of the children; however, the autistic children were significantly less responsive to the experimental manipulation than control subjects. In contrast, the autistic children were no less responsive in terms of other forms of social engagement. Results are interpreted as supporting a model of joint attention deficits in autism that involves factors inherent to the disorder in transaction with social context. 相似文献
