Differing task and motivational characteristics of the competitive setting (viz., task-involving/ego-involving climates, cooperative/individual, and win/loss competitive outcome) were explored in relation to need satisfaction and subjective well-being (SWB). Participants, one-on-one or in pairs, were required to participate in a physical co-ordination task. Results revealed participants exposed to a task-involving condition and those who worked in cooperation to report higher levels of need satisfaction and SWB. Conversely, individuals exposed to ego-involving conditions and those who competed individually experienced higher levels of negative affect. Winning resulted in higher levels of need satisfaction and SWB, whereas losing led to higher levels of negative affect. Losing individually in an ego-involving condition led to the highest levels of negative affect responses and attenuated levels of reported need satisfaction and SWB. Via structural equation modeling, a model of motivational processes grounded in self-determination theory was supported in which elements of the competitive situation that facilitated need satisfaction led to increments in reported indices of SWB. 相似文献

This paper examined conceptual versus perceptual priming in identification of incomplete pictures by using a short-term priming
paradigm, in which information that may be useful in identifying a fragmented target is presented just prior to the target’s
presentation. The target was a picture that slowly and continuously became complete and the participants were required to
press a key as soon as they knew what it was. Each target was preceded by a visual prime. The nature of this prime varied
from very conceptual (e.g., the name of the picture’s category) to very perceptual (e.g., a similar-shaped pictorial prime
from a different category). Primes also included those that combined perceptual and conceptual information (e.g., names or
images of the target picture). Across three experiments, conceptual primes were effective while the purely perceptual primes
were not. Accordingly, we conclude that pictures in this type of task are identified primarily by conceptual processing, with
perceptual processing contributing relatively little. 相似文献

Four monkeys and 6 humans representing five different native languages were compared in the ability to categorize natural CV tokens of /b/ versus /d/ produced by 4 talkers of American English (2 male, 2 female) in four vowel contexts (/i, e, a, u/). A two-choice "left/right" procedure was used in which both percentage correct and response time data were compared between species. Both measures indicated striking context effects for monkeys, in that they performed better for the back vowels /a/ and /u/ than for the front vowels /i/ and /e/. Humans showed no context effects for the percentage correct measure, but their response times showed an enhancement for the /i/ vowel, in contrast with monkeys. Results suggest that monkey perception of place of articulation is more dependent than human perception on the direction of the F2 onset transitions of syllables, since back-vowel F2s differentiate /b/ and /d/ more distinctively. Although monkeys do not provide an accurate model of the adult human in place perception, they may be able to model the preverbal human infant before it learns a more speech-specific strategy of place information extraction. 相似文献

Patients with corticobasal degeneration (CBD) appear to have impaired number knowledge. We examined the nature of their number deficit while we tested the hypothesis that comprehension of larger numbers depends in part on verbal mediation. We evaluated magnitude judgments and performance on number conservation measures rooted in Piagetian theory in nonaphasic patients with CBD (n=13) and patients with a fluent form of progressive aphasia known as semantic dementia (SD; n=15). We manipulated the numbers of the arrays and the visual-spatial properties of the stimuli being compared during magnitude judgments and Piagetian conservation measures. CBD patients were consistently impaired judging the magnitudes of larger numbers (4-9), while they had minimal difficulty with smaller numbers (magnitudes < or = 3). By comparison, SD patients performed all measures of number knowledge at a ceiling level regardless of number magnitude. Neither patient group was significantly impacted by manipulations of the spatial properties of the stimuli. CBD patients' impairment with larger numbers despite minimal aphasia, and SD patients' intact performance despite an aphasia, challenge the proposal that understanding larger numbers depends on verbal mediation. 相似文献

Two studies of the clinical work of experienced psychoanalysts are presented. Study I is a retrospective study of all the analytic work--161 cases--of sixteen analysts from 1973 to 1977, including their evaluations of the treatments at outcome. Study II is a prospective study of the ninety-two cases started in analysis by a group of twenty analysts between 1984 and 1989 and followed to termination, including their reports. The history of each treatment as reported and evaluated by the analyst is examined in terms of: nature of the population, the analyst's view of the case when the initial recommendation was made, duration of treatment, therapeutic benefit, rating of analyzability at termination of treatment, nature of the termination, and cases changed to psychotherapy. Some old shibboleths are challenged as perspective on both the limitations and achievements of psychoanalysis emerges from the findings of the study. 相似文献

Emerging therapies for Alzheimer's disease offer hope to patients and their caregivers. Future treatments will probably include combination approaches with agents that modify amyloid processing, deposition, and clearance. One example, the AD vaccine, reduced amyloid burden and changed behavior in animal models of AD, but the human trial was halted when several subjects developed brain inflammation. Anti-inflammatory agents have epidemiologic support, but clinical trials have been disappointing, possibly related to inadequate study with anti-inflammatory agents that modify amyloid processing. Agents that target known cardiovascular risk factors, such as hypercholesterolemia, hypertension, and insulin resistance, have epidemiologic, preclinical, and clinical evidence to warrant further investigation. Heavy metal chelators, antioxidants, neurotrophic factors, glutaminergic modulators, and agents that modify hyperphosphorylation of Tau are other approaches in research and development. 相似文献

On tasks that require overcoming an obstacle along an existing path to a physically present goal, infants and very young children evince planning. In each of 3 experiments, the authors tested 21- and 27-month-olds' ability to construct a path to a mentally re-presented goal. Across experiments, the authors varied the number and type of cues to the solution provided. After exposure to the goal-state configuration of problems, both age groups showed evidence of planning (Experiment 1). Demonstration of the initial step in the solution path in Experiment 2 was not as effective as exposure to the goal state in Experiment 1. Even with specification of a greater proportion of the goal path, goal-state configuration information was particularly effective in facilitating performance (Experiment 3). The results suggest productive generation of solutions to novel problems by young children; planning is facilitated by goal-state configuration information. 相似文献
