Abstract— The "flash of insight" sometimes observed m problem solving and in scientific discovery has been thought to be due to a sudden cognitive restructuring of the problem situation Direct confirmation of restructuring has been difficult without an independent procedure Graph structures were derived from judgments of concept relatedness made by subjects who had an insight and by several groups who either did not or could not have the insight The graphs of the solvers differed from the graphs of subjects who tried and failed, those who listened to the solvers, and those who were given the solution When other subjects in a subsequent experiment repeatedly judged similarity of pairs of Concepts, there was evidence that those lections critical to the new cognitive order were targeted long before there was the breathtaking cognitive reorganization 相似文献

Summary The capacity to estimate the orientation of an object with respect to gravity was investigated by having Ss rotate a tactile-kinesthetically (tk) perceived bar (under exclusion of all visual cues) to the subjective horizontal. The 1st experiment was conducted to compare tk judgements with the visual judgements obtained by Udo de Haes (1970a,b) about an object's orientation in order to study the underlying mechanism, particularly to show possible vestibular influence, if any. For this purpose Ss were required to orient the tk-perceived bar while subjected to changes in both the magnitude (by centrifugation) and the direction (by tilting the body) of the gravitational force. Great variability of S's adjustments in the nearly inverted body positions (120°, 150°), indicating a low stability of spatial orientation in this range, was common to both tk and visual estimations. The relationship between body tilt and the corresponding judgement about the object's orientation, was however different for the two systems: No linear proportionality to the shear force in the utricles, as was established earlier in the visual experiments of Udo de Haes, was found in the tk settings. Vestibular influence was further studied in the 2nd experiment by comparing bar adjustments of the right hand with those of the left hand. Increasing angles of body tilt produced similar results in the responses of both hands although shifted differently from the true values. Standard deviations of left-hand settings were lower than those of right-hand ones. Reactions to increased gravity differed between hands. In the 3rd experiment the hand-weight alone, not the whole gravitational force, was increased. A direct effect of gravity on the adjusting hand was found. It was concluded that 1) the underlying mechanisms for tk and visual space estimations with respect to gravity are different; 2) with the given tk stimulation vestibular influence is not recognizable; 3) muscle receptors are probably significant, in addition to joint receptors, for this mode of space estimation, and 4) both arms may represent a system to perceive the direction of gravity independent of each other and of the labyrinth. 相似文献

Forgiveness is a core value within Christianity and many other religions, but it is unclear whether valuing forgiveness results in individuals being more forgiving. This study examines the effect of Christian religious belief on forgiveness; tests the theoretical speculation that trust fosters forgiveness; explores the effect of cynicism, and examines age effects on forgiveness with a British sample. Christian clergy (N?=?209), general population samples of Christians (N?=?176), and a group with NRA (N?=?65) completed the Heartland Forgiveness Scale measuring forgiveness of self, others, and situations, and measures of trust, cynicism, and the importance of forgiveness. The clergy score higher on total forgiveness, forgiveness of self, others, and situations; rate forgiveness as being more important; are more trusting; and are less cynical than the Christian and no religious affiliation (NRA) samples in the general population. While the Christian sample value forgiveness more than the NRA group, they are not more forgiving on any of the measures tested. Age is a significant predictor only for situational forgiveness. Trust is not a positive mediator of forgiveness for any of the participant groups, and neither is cynicism a negative mediator of forgiveness. 相似文献

Previous studies (Case, 1985; Siegler, 1981) have shown that children under the age of 5 years have little understanding of balance scales when required to encode the influence of weight or distance from the fulcrum. More recently, however, Halford, Andrews, Dalton, Boag, and Zielinski (2002) noted that an understanding based on weight alone is present even in 2-year-olds. In all these experiments, weight was varied using multiple objects of the same weight. Consequently, the children's decisions could have been based upon visual features (size, number) without necessarily taking the weight into account. The present study investigated whether young children are able to correctly encode the relevance of weight in influencing the behavior of a balance scale. We studied how well 3- to 4-year-old children learn to use one of two different weights (of equal appearance) to tip the scale. In the plausible condition, the heavy weight produced the desired outcome. In the implausible condition, the light weight caused the scale to tip. Only 4-year-olds' performance differed between conditions by learning more effectively in the plausible than the implausible condition. Our results suggest that children younger than 4 years of age have not yet developed clear expectations of the role of weights on the movements of a balance scale. 相似文献

ABSTRACTTo study the nature of irradiation-induced nanofeatures in oxide dispersion strengthened (ODS) Fe-Cr alloys, post-irradiation isochronal thermal annealing up to 600°C was performed for ODS Fe-9%Cr and Fe-14%Cr alloys ion-irradiated at 300°C and 500°C. Nanoindentation indicated hardening for all as-irradiated alloys and complete hardness recovery upon post-irradiation annealing. Cross-sectional TEM indicated an irradiation-induced defect band near peak damage mainly consisting of dislocation loops. Candidate mechanisms of recovery were critically evaluated. Shrinkage of loops via capture of thermal vacancies was found to correctly reflect the annealing behaviour of ODS Fe-9Cr irradiated at 300°C. 相似文献

This study analyzed the provision of outpatient psychotherapy services in Germany in typical practice settings. In a representative survey (from June 2008 to September 2009) 1,212 subjects who received outpatient psychotherapy during the past 6 years were questioned about their experiences with outpatient psychotherapy via telephone interviews. Socio-economic data, reasons for seeking treatment, access paths, financial resources and psychosocial support data were collected. Therapeutic settings and modalities and concomitant medication treatment are described. The findings illustrate the problem of multiple psychiatric morbidity in the clinical practice and confirm the urgent need for patient access to professional psychotherapeutic services. Improving access to these services requires close cooperation between care providers. 相似文献

In this cross-sectional study, we explored the relationship between premorbid personality and its changes over 5 years, and cognitive deterioration in patients with mild Alzheimer’s disease. The cognitive level of 54 patients was compared with that of 64 control subjects using the Mini Mental State (MMSE). Family members completed the NEO-PI-R (form R) twice, once to evaluate the participants’ current personality and again to assess personality traits as they were remembered to be 5 years earlier. Furthermore, the family filled in the Informant Questionnaire on Cognitive Decline (IQCODE), the Activities of Daily Living (ADL), and the Instrumental Activities of Daily Living (IADL) scales to assess their proxies’ cognitive level and daily living functioning. Regarding the relationship between personality characteristics and cognitive status, we observed trends for premorbid personality and significant links for personality changes in the clinical group. Thus, changes in neuroticism and conscientiousness were associated with cognitive deterioration, whereas decreased openness to experience and conscientiousness over time predicted loss of independence in daily functioning in the clinical group. Our study suggests that premorbid features can be considered as latent traits linked to the neuropathology underlying the disease process, while personality changes are probably the consequences of the pathological process. 相似文献

The present research introduces the concept of decisional fit. A decision maker experiences decisional fit when the individually preferred decision strategy fits the actually applied strategy. In accordance to other fit‐concepts in psychology (e.g., person–environment fit), we expected positive effects of decisional fit. Five studies examine the effects of a fit between the individual preference for intuition and deliberation (PID) and the actually used decision strategy (intuition or deliberation). A comparison of extreme types (according to participants' values on the PID scale) revealed that decisional fit enhances the perceived value of the chosen or evaluated object (Studies 1–3). In Studies 4 and 5, participants experienced less regret after decisional fit. The findings highlight the importance of considering individual differences when comparing intuitive and deliberate decision making, because strategy preferences interact with applied strategies.
