The notion is expressed in the DSM-IV that some personality disorders (PDs) tend to remit with age whereas other types do not. This notion is supported by the literature and the study reported here. Studies published between 1951 and 2000 show that (1) in old age, PDs are prevalent both in normal subjects and to a greater extent in the mentally ill; (2) the evidence for general age-relatedness of PDs is scarce and contradictory; (3) there is evidence for specific age-relatedness of PDs in old age. This empirical study focused on the prevalence of PDs in five different age groups ranging from adolescence to old age. It included both community residents (N = 623, aged 17-87), and mental health patients (N = 315, aged 18-86). Dimensional scores for PDs were assessed by means of the DSM-III-R- and ICD-10- based self-report Questionnaire of Personality Traits (VKP) (Duijsens, Eurelings-Bontekoe & Diekstra, 1996). There was consistent evidence for a specific effect of aging: community residents in the oldest age group reported more schizoid and more obsessive-compulsive characteristics compared to one or more of the younger age groups. Older mental health patients showed more schizoid disorder characteristics and fewer high-energy disorder characteristics compared to one or more of the younger patient groups. 相似文献

The objective of this exploratory one-group pretest-posttest study was to evaluate the nature of psychological change in inward depressed psychiatric patients attending multi-disciplinary treatment, including physical activity, designed to improve mental well-being. Female depressed psychiatric patients (n?=?51) were examined before and after this programme over a period of 3 months. The following psychological parameters were assessed: depression, anxiety, global self-esteem, and physical self-perceptions. Depressed patients demonstrated statistically significant improvements in depression, anxiety, global self-esteem and physical self-worth (t(50) ranging from -3.76 to 4.65, all p?0.007; ES ranging from 0.53 to -0.65). Changes in depression and anxiety displayed a strong negative correlation with changes in global self-esteem, and those changes are independent of the initial severity of the depressive symptoms (?F(2,48) ranging from 0.03 to 0.70, n.s.). Patients with greater improvement in physical self-perceptions reported greater improvement anxious symptoms then patients who did not improve. Consequently, within the limitations of the research design it can be concluded that the programme appeared successful in improving psychological well-being in female depressed patients. Results also provide preliminary insight into the potential role of the physical self in recovery. 相似文献

Patients with right unilateral cerebral stroke, four of which showed acute hemispatial neglect, and healthy aged-matched controls were tested for their ability to grasp objects located in either right or left space at near or far distances. Reaches were performed either in free vision or without visual feedback from the hand or target object. It was found that the patient group showed normal grasp kinematics with respect to maximum grip aperture, grip orientation, and the time taken to reach the maximum grip aperture. Analysis of hand path curvature showed that control subjects produced straighter right hand reaches when vision was available compared to when it was not. The right hemisphere lesioned patients, however, showed similar levels of curvature in each of these conditions. No behavioural differences, though, could be found between right hemisphere lesioned patients with or without hemispatial neglect on either grasp parameters, path deviation or temporal kinematics. 相似文献

Cueing effects, i.e., early facilitation of reaction time and inhibition of return (IOR), are well-established and robust phenomena characterizing exogenous orienting and are widely observed in experiments with a traditional Posner cueing paradigm. Krüger, MacInnes, and Hunt (2014) proposed that facilitatory effects of peripheral cues are the result of a cue-target perceptual merging due to re-entrant visual processing. To test the role and timing of these feedback mechanisms in peripheral cueing effects, we modified the traditional cueing task in Experiments 1-3 by interleaving pre- and post-cue trials at the valid and invalid location and random cue-target onset asynchrony (CTOA) ranging from ?300 to +1,000 ms. Analysis of the manual reaction time distribution over CTOA showed well-pronounced IOR in the valid pre-cue condition and a small cost of perceptual merging in the post-cue condition, but no early facilitation of reaction time was observed in the pre-cue condition. In Experiment 4, we tested directly whether temporal ambiguity eliminated facilitation by restricting CTOAs to only the pre-cue time range and including a between-subject manipulation of a) random, b) mixed discrete, and c) blocked discrete CTOAs. Results obtained in the continuous and binned conditions showed no facilitation but robust IOR. We found both early facilitation and IOR in the blocked condition. Overall, the present findings show a small perceptual merging result without accompanying facilitation, suggesting different underlying mechanisms. Second, they demonstrate that early facilitation is likely to be affected by the presence or absence of temporal expectations and that the early onset of IOR might be masked by stronger facilitation in traditional cueing experiments. 相似文献

Background and Objectives: We investigated how adolescents from five regions around the world perceived and coped with parent- and peer-related stress. Design: The study comprised N = 4957 adolescents (mean age of 15.2 years) from 18 countries. Methods: The study used self-report measures for stress perception and coping style. Results: Across countries, adolescents perceived parent-related stress to be considerably greater than peer-related stress. They coped less actively with parent-related stress than with peer-related stress. Significant differences emerged with respect to geographic region and key demographic indicators. Adolescents from Eastern European and Western countries had generally quite low levels of stress. Adolescents from Southern Europe exhibited the highest stress levels and the greatest coping activity in dealing with stress in both domains, whereas adolescents from Southern Emerging and Asian countries reported high levels of parent-related stress and dealt much less actively with parent-related stress than with peer-related stress. Conclusions: Adolescents from all countries were remarkably competent in dealing with relationship stressors. Cultural and regional differences have a stronger effect on stress perception and coping style than gender. 相似文献

Particular differences between an object and its surrounding cause salience,
guide attention, and improve performance in various tasks. While much research
has been dedicated to identifying which feature dimensions contribute to
salience, much less regard has been paid to the quantitative strength of the
salience caused by feature differences. Only a few studies systematically
related salience effects to a common salience measure, and they are partly
outdated in the light of new findings on the time course of salience effects. We
propose Bundesen’s Theory of Visual Attention (TVA) as a theoretical basis for
measuring salience and introduce an empirical and modeling approach to link this
theory to data retrieved from temporal-order judgments. With this procedure, TVA
becomes applicable to a broad range of salience-related stimulus material. Three
experiments with orientation pop-out displays demonstrate the feasibility of the
method. A 4th experiment substantiates its applicability to the luminance
dimension. 相似文献

Implementation intentions are if-then plans that spell out when, where, and how a set goal has to be put into action: If situation x is encountered, then I will perform behavior y!, thereby linking a critical situation with a goal-directed behavior. Over the last fifteen years, implementation intentions, as compared to simple goal intentions (I intend to reach z!), have demonstrated their effectiveness as self-regulation strategies in promoting desired behaviors or when unpleasant actions have to be carried out. By forming implementation intentions, the control of unwanted influences (e.g., temptations, bad habits, adverse self-states) on an ongoing goal pursuit can also be facilitated. Furthermore, implementation intentions have been shown to ease goal-directed actions in critical populations such as patients with a frontal brain lesion, schizophrenic patients, and opiate addicts in withdrawal, for whom the initiation problems of the goaldirected action are more accentuated. 相似文献
