Analysis of accuracy of responses to balance scale problems gives a global idea of the cognitive processes that underlie problem-solving behavior on this task. We show that response times (RTs) provide additional detailed information about the kind and duration of these processes. We derive predictions about the RTs from Siegler's (1981) model for the balance scale task, including the counterintuitive prediction that young adults are slower than children in solving particular balance scale problems. The predictions were tested in a study in which 191 6- to 22-year-old participants were presented with a computerized balance scale task. RTs were analyzed with regression models. In addition to qualitative differences between items, we also modeled quantitative differences between items in the regression models. Analyses supported the predictions and provided additional knowledge on the rules. Rule II was reformulated as a rule that always involves the encoding, but not always the correct application of the distance cue. RTs provided evidence for the use of a buggy-rule and not an addition-rule. Finally, a relation between rule inconsistency and increased RT was found. 相似文献

Although the notion of a down low life style, called various things at various times, has a long history in the black community, the past few years have been marked by an exponential increase in attention of this phenomenon in both the mainstream press and scholarly work. However, much of this work has focused on exploring whether men on the down low present a unique threat for HIV infection to black women. Currently, there exist very few scholarly works exploring the lives of black men who have sex with men and women that specifically address their own experiences living on the down low or how these men personally define what it means to be on the down low. In this article, we explore why black men who have sex with men and black men who have sex with men and women, including those who self-identify as gay, bisexual or as being on the down low, come to use the down low label and what it means to them to be on the down low. 相似文献

This paper follows the tradition of treating Zhuangzi's Butterfly Dream episode as presenting a version of skepticism. However, unlike the prevalent interpretations within that tradition, it attempts to show that the skepticism conveyed in the episode is more radical than it has been conceived, such that the episode can be read as a skeptical response to Descartes’ refutation of skepticism based on the Cogito, ergo sum proof. The paper explains how the lack of commitment in Zhuangzi to the dubious assumption about ‘I’ that it necessarily refers to something existing to which Descartes seems to uncritically adhere allows Zhuangzi to doubt what for Descartes is absolutely indubitable: I exist. 相似文献

We present a review of empirical evidence that suggests that a substantial portion of phenotypic variance is due to nonlinear (epigenetic) processes during ontogenesis. The role of such processes as a source of phenotypic variance in human behaviour genetic studies is not fully appreciated. In addition to our review, we present simulation studies of nonlinear epigenetic variance using a computational model of neuronal network development. In each simulation study, time series for monozygotic and dizygotic twins were generated and analysed using conventional behaviour genetic modelling. In the results of these analyses, the nonlinear epigenetic variance was subsumed under the non-shared environmental component. As is commonly found in behaviour genetic studies, observed heritabilities and unique environmentabilities increased with time, whereas common environmentabilities decreased. The fact that the phenotypic effects of nonlinear epigenetic processes appear as unsystematic variance in conventional twin analyses complicates the identification and quantification of the ultimate genetic and environmental causes of individual differences. We believe that nonlinear dynamical system theories provide a challenging perspective on the development of individual differences, which may enrich behaviour genetic studies. 相似文献

Abstract In the days and weeks following the Oklahoma City bombing on April 19,1995, Oklahoma state authorities, university faculty and staff, and leading experts from across the nation formed a coalition to address issues of clinical service delivery, educational intervention, and research. This article focuses on the centralized approach applied to the administration of research endeavors. This centralization was designed to minimize revictimization of both survivors and affected families, enhance the quality of data collected, and facilitate cooperation between participating investigators. The resultant set of projects includes a variety of research methodologies and study populations and will serve to significantly enhance understanding of the mental health sequelae of such disasters. 相似文献

Perceivers generally show a poor ability to detect changes, a condition referred to as “Change Blindness” (CB). They are, in addition, “blind to their own blindness”. A common explanation of this “Change Blindness Blindness” (CBB) is that it derives from an inadequate, “photographical” folk-theory about perception. This explanation, however, does not account for intra-individual variations of CBB across trials. Our study aims to explore an alternative theory, according to which participants base their self-evaluations on two activity-dependent cues, namely search time and perceived success in prior trials. These cues were found to influence self-evaluation in two orthogonal ways: success-feedback influenced self-evaluation in a global, contextual way, presumably by recalibrating the norm of adequacy for the task. Search time influenced it in a local way, predicting the success of a given trial from its duration. 相似文献

This study develops a Science–Technology–Society (STS)-based science ethics education program for high school students majoring in or planning to major in science and engineering. Our education program includes the fields of philosophy, history, sociology and ethics of science and technology, and other STS-related theories. We expected our STS-based science ethics education program to promote students’ epistemological beliefs and moral judgment development. These psychological constructs are needed to properly solve complicated moral and social dilemmas in the fields of science and engineering. We applied this program to a group of Korean high school science students gifted in science and engineering. To measure the effects of this program, we used an essay-based qualitative measurement. The results indicate that there was significant development in both epistemological beliefs and moral judgment. In closing, we briefly discuss the need to develop epistemological beliefs and moral judgment using an STS-based science ethics education program. 相似文献
