To investigate why 3-year-olds have difficulty in switching sorting dimensions, children of 3 and 4 years were tested in one of four conditions on Zelazo's card sort task: standard, sleeve, label and face-up. In the standard condition, children were required to sort blue-truck and red-star cards under either a blue-star or red-truck model card, first by color or shape, and then by the other dimension. Here 3-year-olds sorted correctly until the dimension changed; they continue to sort by the initial dimension. The sleeve condition (placing the sorting cards in an envelope prior to sorting) had little effect. In the label condition, the child labeled the relevant sorting dimension on each trial. Most 3-year-olds succeeded; evidently their labeling helped them refocus their attention, overcoming ‘attentional inertia’ (the pull to continue attending to the previously relevant dimension). In the face-up condition, attentional inertia was strengthened because sorted cards were left face-up; 4-year-olds performed worse than in the standard condition. We posit that attentional inertia is the core problem for preschoolers on the card sort task. 相似文献

Researchers often debate about whether there is a meaningful differentiation between psychological well-being and subjective well-being. One view argues that psychological and subjective well-being are distinct dimensions, whereas another view proposes that they are different perspectives on the same general construct and thus are more similar than different. The purpose of this investigation was to examine these two competing views by using a statistical approach, the bifactor model, that allows for an examination of the common variance shared by the two types of well-being and the unique variance specific to each. In one college sample and one nationally representative sample, the bifactor model revealed a strong general factor, which captures the common ground shared by the measures of psychological well-being and subjective well-being. The bifactor model also revealed four specific factors of psychological well-being and three specific factors of subjective well-being, after partialling out the general well-being factor. We further examined the relations of the specific factors of psychological and subjective well-being to external measures. The specific factors demonstrated incremental predictive power, independent of the general well-being factor. These results suggest that psychological well-being and subjective well-being are strongly related at the general construct level, but their individual components are distinct once their overlap with the general construct of well-being is partialled out. The findings thus indicate that both perspectives have merit, depending on the level of analysis. 相似文献

Individual semi-structured interviews were conducted with 17 individuals who had experienced a traumatic spinal cord injury (SCI), focusing on the participants' lived experience of SCI. The interviews were transcribed verbatim and were analysed for recurrent themes using interpretative phenomenological analysis (IPA). Here, we present three inter-related recurrent themes all concerning difficulties in adjusting to home life following hospital discharge: "loss of camaraderie", "lack of post-discharge care" and "other people's reactions to spinal cord injury". Participants reported that the camaraderie they formed with fellow patients during their rehabilitative stay in hospital generated feelings of security and community. This was discussed in stark contrast to the isolation and loneliness that they subsequently experienced post-hospital discharge. A perceived lack of physical, practical and psychological support coupled with negative and stigmatising reactions of the wider community served to make adjustment to home life post-SCI particularly difficult for the participants. The findings are discussed in relation to extant SCI literature, and recommendations for future health care of individuals with SCI are made. 相似文献

Understanding (a) how responses become prepotent provides insights into when inhibition is needed in everyday life. Understanding (b) how response prepotency is overcome provides insights for helping children develop strategies for overcoming such tendencies. Concerning (a), on tasks such as the day‐night Stroop‐like task, is the difficulty with inhibiting saying the name of the stimulus due to the name being semantically related to the correct response or to its being a valid response on the task (i.e. a member of the response set) though incorrect for this stimulus? Experiment 1 (with 40 4‐year‐olds) suggests that prepotency is caused by membership in the response set and not semantic relation. Concerning (b), Diamond, Kirkham and Amso (2002) found that 4‐year‐olds could succeed on the day‐night task if the experimenter sang a ditty after showing the stimulus card, before the child was to respond. They concluded that it was because delaying children’s responses gave them time to compute the correct answer. However, Experiment 2 (with 90 3‐year‐olds) suggests that such a delay helps because it gives the incorrect, prepotent response time to passively dissipate, not because of active computation during the delay. 相似文献

Contemporary epistemology has assumed that knowledge is represented in sentences or propositions. However, a variety of extensions and alternatives to this view have been proposed in other areas of investigation. We review some of these proposals, focusing on (1) Ryle's notion of knowing how and Hanson's and Kuhn's accounts of theory-laden perception in science; (2) extensions of simple propositional representations in cognitive models and artificial intelligence; (3) the debate concerning imagistic versus propositional representations in cognitive psychology; (4) recent treatments of concepts and categorization which reject the notion of necessary and sufficient conditions; and (5) parallel distributed processing (connectionist) models of cognition. This last development is especially promising in providing a flexible, powerful means of representing information nonpropositionally, and carrying out at least simple forms of inference without rules. Central to several of the proposals is the notion that much of human cognition might consist in pattern recognition rather than manipulation of rules and propositions.The preparation of this article was supported in part by National Institutes of Health Grants No. NICHD-19265 and NICHD-06016.

Conceptions reported by various authors concerning omen dreams and prophetic nightmares are described followed by five brief case reports. Therapeutic approaches were primarily insight-oriented and educational but also included direct testing of associated superstitions and interactions with dream images in the awake state.An earlier version of this paper was presented at the Annual Meeting of the Association for the Study of Dreams, Ottowa, Canada, June 1986. 相似文献

Microcounselling approaches involve teaching the component behaviours of effective counselling or interviewing within a problem-solving framework. Egan, Ivey and Carkhuff, as proponents of this view, stress that later action stages of the problem-solving cycle should be based on an adequate understanding of the client's problem. The relationship between the skills which comprise the microcounselling approach and the goal of problem understanding is examined. It is argued that the approach lacks any explanation of how problem understanding is reached, and that it concentrates instead on the communication techniques involved in the discovery and modification of the client's understanding. This omission leaves counsellors without a rationale for the modification of their clients' views and without a means to regulate their use of the various microskills. Information theory and recent research on complex problem-solving are introduced to explain the skills involved in reaching a high-quality understanding of a client's problem. Given that these complex cognitive processes are not addressed in the microcounselling approach, suggestions are made for its modification. 相似文献

In two experiments, pigeons were trained on two-component multiple schedules in which responding in one component (S1) was always maintained by a variable-interval schedule. In Experiment I, low response rates were reinforced in the second (S2) component for six master subjects. This schedule was adjusted to equate reinforcement frequencies in the two components. These subjects were compared to yoked partners, for which reinforcement in the S2 component was made available on a variable-interval schedule whose value was determined by the master subjects. A similar procedure was used in Experiment II, where the S2 schedule for master subjects made reinforcers contingent on the absence of responding. No evidence was found in either experiment for a behavioral contrast effect in the S1 component attributable to response reduction in the S2 component. A reliable contrast effect was obtained from a group of pigeons given extinction conditions in the S2 component, which was compared to a group maintained throughout on a multiple variable-interval schedule. The results suggest that previous indications of behavioral contrast in similar situations were probably caused by uneven reinforcement distributions or reflect uncontrolled fluctuations in response rates. 相似文献

Behavioral contrast was obtained in two experiments, which both employed a standard free-operant successive discrimination (a multiple variable-interval extinction schedule), without the occurrence of reductions of response rate in the extinction component. In Experiment I, one group of four pigeons was trained on a multiple schedule in which one stimulus was associated with a variable-interval schedule and the second stimulus with response-independent reinforcement on a free variable-interval schedule. Though by the end of this training three pigeons were responding very little to the second stimulus, when this stimulus was associated with extinction all subjects showed a contrast effect. In Experiment II, eight pigeons were trained extensively to respond to a single stimulus on a variable-interval schedule, before a second stimulus associated with extinction was introduced. This second stimulus was dissimilar to the initial stimulus and five pigeons never responded in its presence. Nevertheless, all pigeons showed a contrast effect and there was no evidence that the effect was smaller in errorless subjects or smaller than in a subsequent discrimination where all subjects made many errors. Both experiments indicated that response reduction in one component of a multiple schedule is not a necessary condition for the occurrence of contrast. 相似文献
