As a word moves from isolation in a list to being contextually bound in meaningful discourse, its probability of priming in tests of implicit memory decreases. The present experiments explore whether considerable priming effects can be revealed with conceptual tests of implicit memory as compared to perceptual tests. In the study phase, meaningful actions were described within a coherent text. In Experiment 1 subjects elaborated half of the actions by visual imagery. In Experiment 2, subjects elaborated the actions by enacting them symbolically. In both experiments, subjects in a control condition were simply required to read the same activities. In Experiment 2, a further group of subjects had to detect orthographic errors. The results demonstrated reliable effects of implicit memory in terms of associations with verbs repeated from the studied text. This form of repetition priming for textual materials in a conceptual test of implicit memory was enhanced by both types of elaboration. A word-stem completion task for the same targets revealed a less pronounced and inconsistent priming effect, uninfluenced by both types of elaboration. But the latter form of perceptual priming was found to be more pronounced within the error-detection condition. Measures of explicit memory showed similar effects of elaborative encoding conditions but there were some dissimilarities to measures of implicit memory, too. In general and in accordance with a transfer-appropriate processing view, conceptual tests rather than perceptual tests may be more suitable for detecting effects of implicit memory within the domain of text processing. 相似文献

The aim of this study was to scrutinize the relationship between personality type as described by Grossarth-Maticek and Eysenck, health-related behaviours, and indicators of transitory ill health in a community sample. The sample consisted of all per sons aged 40 years (45 men and 35 women) in a Swedish municipality who agreed to take part in a health examination at the primary health care centre of the municipality. The Short Interpersonal Reactions Inventory (Grossarth-Maticek and Eysenck, 1990) was used to measure personality type. Self-report data were obtained regarding seven health-related behaviours. Health was assessed in three ways; self-report (paper and pencil), self-report (interview response to physician), and measures of 36 biological variables including immune system indicators. The allocation of persons to the different personality types proved problematic using the established methods. By combining the types, according to Eysenck's personality model, and performing a cluster analysis on this combination, a ‘healthy’ and a ‘stressed’ profile were identified within both the male and the female group of subjects. Persons in the healthy personality cluster showed more favourable scores on the health-related behaviour indices and on the self-report health scales than the persons in the stressed cluster. They also tended to score lower than those in the stressed cluster on most of the biological markers known to increase during acute stress. The possibility that this implies a higher level of strain for the persons in the stressed cluster on various bodily systems is discussed. 相似文献

Intractable controversies and other types of policy disagreements correspond to policy problems with a different structure.
The more structured a problem is, the more consensus there is about which values and information are at stake in the process
of problem solving. Policymakers like to treat problems in as structured a way as possible. Three policy strategies are described
to move away from the unstructured to the more structured problem type. However, policymakers run the risk of oversimplifying
an ill-structured problem, which means that elements of the problem situation relevant to other actors are overlooked or denied.
Hence, policy controversies may become intractable. The remedy is a fourth strategy, characterised by problem structuring.
This strategy requires political participation of actors with different views on the problem, and an argued political problem
choice.
His main research areas are problem structuring in public policy, knowledge use, environmental risk, technology and democracy.
He is currently working on knowledge-based policy strategies for addressing the issue of climate change.
His research interest is to develop and apply discursive and/or argumentative approaches to the policy process. 相似文献

What visual information do children normally require for the control of reaching movements? How is performance affected when children do not have access to the preferred mode of perceptual information? These questions were studied in 28 children who were tested on 3 occasions: at 6, 7, and 8 years of age. The task was to pick beads, 1 at a time, from 1 cup and carry them to another cup. With the aid of a mirror arrangement and a curtain, the amount of visual information was manipulated with regard to both the target and the performing hand. The movements were monitored with an optoelectronic device (SELSPOT II) and analyzed in terms of transport and object-handling phases. Results showed that object handling required visual information on both hand and target. For the transport phase of the movement, visual information on the spatial location of the target was sufficient, and sight of the hand did not improve performance. In contrast to adult subjects, when children did not have access to the required visual information, their performances deteriorated markedly. These results indicate that from the age of 6, children use visual information for control of arm movements in a manner like that of adults, although with less accuracy and speed. However, even 8-year-old children are limited in their ability to use alternative perceptual strategies for movement control, and they therefore become less flexible and more dependent on visual information. 相似文献

To test the hypothesis that the major evaluative beliefs postulated by Rational-Emotive Behaviour Therapy are related to marital adjustment, 50 married couples completed the Dyadic Adjustment Scale (DAS) and the Survey of Personal Beliefs (SPB). Significant correlations were found between DAS scores and three subscales (Other directed shoulds, Low frustration tolerance and Self worth) of the SPB. On the interpersonal dimension of assumed similarity, females in the high dyadic adjustment group were better able to predict their spouses' awfulizing, low frustration tolerance and self-worth beliefs than were females in the low adjustment group. However, the present study offers only limited support for the hypothesis that interpersonal perception of irrational evaluative beliefs is related to marital adjustment. 相似文献

Speech can be described either in terms of acoustics, as a perceptual outcome, or as a motor event. Central to theories of speech perception and production is an attempt to describe how these aspects of speech are interrelated. The present experiment investigated how the nonstutterers' and stutterers' reproductions of acoustically presented interrogative sentences were influenced by experimental variations of intonation (sentence initial vs. sentence final) and speech rate (normal vs. time compressed). We studied the effects of these stimulus manipulations on the speech rate and fundamental frequency (F0
) of 10 adult German-speaking nonstutterers and seven stutterers. Experimental manipulations of intonation and speech rate significantly influenced the syllable duration and speech rate of both normal speakers and stutterers. The fundamental frequency of the subjects' responses were also significantly influenced by the intonation of the stimulus. But the stutterers' increase in F0
for stressed syllables was generally less pronounced than that of nonstutterers. These results imply that (a) the subjects not only extract linguistic meaning from intonation but that they also store extragrammatical speech rate information, and (b) the speakers adopt these speech rate variations for their own productions. Generally, these results demonstrate that speech perception is not limited to extracting linguistically invariant information. The results show that speakers actively generate their own prosody and that this generative process is influenced by the prosodic structure of another speaker's antecedent speech. The implications of these results for theories of speech production are discussed. 相似文献

We investigated the nature of the relationship between experiences of transcendental consciousness and psychological health. In Study 1, three groups with different levels of experience in transcendental meditation (TM) and in the TM-Sidhi program (techniques that have been shown to produce experiences of transcendental consciousness) were studied, using the self-investigation method of Hermans (1976). We employed blind interviewers and raters with various attitudes toward TM to minimize the possible impact of a variety of artifacts. Cross-sectionally, experience with TM and the TM-Sidhi program was positively related to a general measure of psychological health (p = .002); longitudinally, the meditating groups improved more than the control group on the psychological health measure (p less than .03). In Study 2, two contrast groups of long-term participants were similar on several confounding variables but differed on physiological indicators of experiences of transcendental consciousness. The groups with the positive physiological indicators showed a trend toward higher scores on the psychological health factor (p = .092), indicating that psychological health may be developed through the systematic cultivation of transcendental meditation and the TM-Sidhi program. 相似文献
