The in‐group preference and self‐concepts of urban Aboriginal‐Australian and Anglo‐Australian children have never been compared, nor their relationships to teachers' evaluations of academic performance. In this study, 60 Aboriginal (primarily local Nyoongah) and 60 Anglo children aged 6–12 years were tested on in‐group preference; children aged 8+ were tested on self‐concept. Also, their teachers evaluated them on their general academic performance. Results indicated that Anglo children showed greater in‐group preference and scored higher on teacher evaluations than Aboriginal children, although there was no difference on self‐concept. No correlation existed between in‐group preference and self‐concept. It was concluded that the problems faced by Aboriginal children are only likely to be alleviated by a great deal of structural change. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

Engineering science is a scientific discipline that from the point of view of epistemology and the philosophy of science has
been somewhat neglected. When engineering science was under philosophical scrutiny it often just involved the question of
whether engineering is a spin-off of pure and applied science and their methods. We, however, hold that engineering is a science
governed by its own epistemology, methodology and ontology. This point is systematically argued by comparing the different
sciences with respect to a particular set of characterization criteria.

Two studies examined the reduction of triggered displaced aggression (TDA) via bottom‐up processing modes of de‐categorization. Participants were provoked by the experimenter and then interacted with an ostensible out‐group member who either did or did not provide a second (triggering) provocation. Study 1 compared TDA toward a triggering out‐group member who had previously been either differentiated from the out‐group, made the focus of self‐other comparison, or was in a no‐information control condition. As predicted, both differentiation and self‐other comparison reduced aggression relative to the control condition. Study 2 examined the effect of negative self‐disclosure from the out‐group target, and contrasted its effects with both self‐other comparison with a negative other, and a no‐information control condition. As predicted, triggered participants in the negative self‐disclosure condition aggressed less than those triggered in the negative self‐other comparison or no‐information control conditions. The liking induced by self‐disclosure mediated its aggression‐reducing effect. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Most conceptions of episodic memory hold that reinstatement of encoding operations is essential for retrieval success, but the specific mechanisms of retrieval reinstatement are not well understood. In three experiments, we used saccadic eye movements as a window for examining reinstatement in scene recognition. In Experiment 1, participants viewed complex scenes, while number of study fixations was controlled by using a gaze-contingent paradigm. In Experiment 2, effects of stimulus saliency were minimized by directing participants' eye movements during study. At test, participants made remember/know judgments for each recognized stimulus scene. Both experiments showed that remember responses were associated with more consistent study-test fixations than false rejections (Experiments 1 and 2) and know responses (Experiment 2). In Experiment 3, we examined the causal role of gaze consistency on retrieval by manipulating participants' expectations during recognition. After studying name and scene pairs, each test scene was preceded by the same or different name as during study. Participants made more consistent eye movements following a matching, rather than mismatching, scene name. Taken together, these findings suggest that explicit recollection is a function of perceptual reconstruction and that event memory influences gaze control in this active reconstruction process. 相似文献

Home observations, ratings of interaction, and interviews were carried out in families with first-born 5-month-old infants. Comparisons were made between two groups of families differing as to whether the childbirth had been a Cesarean or vaginal delivery. Fathers whose babies had been born by Cesarean delivery reported greater involvement in child care and were rated as more responsive to infant distress. Both mothers and fathers tended to show less animation in interactions with their infants following a Cesarean delivery: mothers engaged less frequently in vigorous physical stimulation and showed less reciprocal positive affect with their infants, and fathers smiled less at their infants. 相似文献

In this paper I discuss two fundamental challenges concerning Crispin Wright’s notion of entitlement of cognitive project: first, whether entitlement is an epistemic kind of warrant since, seemingly, it is not underwritten by epistemic reasons, and, second, whether, in the absence of such reasons, the kind of rationality associated with entitlement is epistemic in nature. The paper investigates three possible lines of response to these challenges. According to the first line of response, entitlement of cognitive project is underwritten by epistemic reasons—and thus supports epistemic rationality—because, when P is an entitlement, trust in P is a dominant strategy with respect to promotion of epistemic value. The second line of response replaces dominance with maximization of expected utility. I argue that both of these proposals are flawed and develop an alternative line of response. 相似文献

In this paper we analyse the degree to which a distinction between social science and public health research and other non-research
activities can account for differences between a number of large scale social surveys performed at the national and European
level. The differences we will focus on are differences in how participation is elicited and how data are used for government,
research and other purposes. We will argue that the research / non-research distinction does not account for the identified
differences in recruitment or use and that there are no other convincing justifications. We argue that this entails that eliciting
participation by coercion or manipulation becomes very difficult to justify. 相似文献

In complex navigation using landmarks, an animal must discriminate between potential cues and show context (condition) sensitivity. Such conditional discrimination is considered a form of complex learning and has been associated primarily with vertebrates. We tested the hypothesis that octopuses and cuttlefish are capable of conditional discrimination. Subjects were trained in two maze configurations (the conditions) in which they were required to select one of two particular escape routes within each maze (the discrimination). Conditional discrimination could be demonstrated by selecting the correct escape route in each maze. Six of ten mud-flat octopuses (Octopus bimaculoides), 6 of 13 pharaoh cuttlefish (Sepia pharaonis), and one of four common cuttlefish (S. officinalis) demonstrated conditional discrimination by successfully solving both mazes. These experiments demonstrate that cephalopods are capable of conditional discrimination and extend the limits of invertebrate complex learning. 相似文献

Bivariate dual change score models were applied to longitudinal data from the Swedish Adoption/Twin Study of Aging to compare the dynamic predictions of 2-component theories of intelligence and the processing speed theory of cognitive aging. Data from up to 5 measurement occasions covering a 16-year period were available from 806 participants ranging in age from 50 to 88 years at the first measurement wave. Factors were generated to tap 4 general cognitive domains: verbal ability, spatial ability, memory, and processing speed. Model fitting indicated no dynamic relationship between verbal and spatial factors, providing no support for the hypothesis that age changes in fluid abilities drive age changes in crystallized abilities. The results suggest that, as predicted by the processing speed theory of cognitive aging, processing speed is a leading indicator of age changes in memory and spatial ability, but not verbal ability. 相似文献
