ABSTRACT Most Western societies face the challenge of steadily ageing workforces. In recent decades, research on ageing has intensively focused on the subjective age concept to understand the challenges and risks of increasingly ageing workforces. Nevertheless, the subjective age construct is subject to several conceptual uncertainties, namely, regarding its stability and potential work-specific drivers of subjective age. We address these limitations by a) investigating the stability of subjective age in a worker sample, and b) identifying work-specific drivers (e.g., negative work events, positive work events, work stress) of subjective age perceptions. Building on social identity and lifespan theories, we test our conceptual assumptions with an online sample of 168 U.S. employees, applying growth curve modelling in a daily diary study over one workweek. Results indicate that subjective age is a mutable construct and varies between- and within-person in the course of a workweek. We identify positive work events and work stress as between-person drivers and negative work events as a within-person driver of subjective age. We discuss theoretical implications of these findings as well as consequences for practitioners. 相似文献

We tested adolescents growing up in institutional care and adolescents living with their birth families using the ‘Do you know?’ scale and other measures of psychosocial functioning. We found that children living in group homes knew significantly less of their family history, exhibited more behavioural problems and had a more external locus of control. Moreover, the correlations between self-esteem and knowledge of family history were significantly different between the groups. This may suggest that the contribution of the knowledge of family history to self-esteem is different depending on the quality of family history. We also found a significant correlation between locus of control and behavioural problems for the children in institutional care, but not children living with their birth families, which may indicate that their behavioural problems may partially stem from the sense of lack of control over their lives. 相似文献

This study aimed to design a program incorporating a narrative perspective that promotes resilience. A program was implemented that conveys an appreciation for the internal qualities of a familiar other person through the creation of a story about them. The experiment was conducted with 36 pairs of women; each pair had a “giver” and a “recipient.” The giver created a story that praised the “good points” of the recipient. There were significant increases in recipients' scores on measures of resilience, self-esteem, and sense of acceptance of the giver. Additionally, the use of a story can help expand the interpretative ability of receiving and expressing praise. 相似文献

Given a drift diffusion model with unknown drift and boundary parameters, we analyse the behaviour of maximum likelihood estimates with respect to changes of responses and response times. It is shown analytically that a single fast response time can dominate the estimation in that no matter how many correct answers a test taker provides, the estimate of the drift (ability) parameter decreases to zero. In addition, it is shown that although higher drift rates imply shorter response times, the reverse implication does not hold for the estimates: shorter response times can decrease the drift rate estimate. In the light of these analytical results, we illustrate the actual impact of the findings in a small simulation for a mental rotation test. The method of analysis outlined is applicable to a broader range of models, and we emphasize the need to further check currently used reaction time models within this framework. 相似文献

AbstractThe purpose of this study was to facilitate sensory feedback, with textured foot orthotics, to evaluate dynamic stability and turning behavior in Parkinson’s disease individuals. Seven participants with a diagnosis of idiopathic Parkinson’s disease, aged 55–80?years old, participated in this study. Participants completed three testing sessions; baseline, 4?weeks post-baseline, and 5?weeks post-baseline. Three experimental conditions were tested: footwear only (F), footwear?+?non-textured orthotic (FO), and footwear?+?textured orthotic (FOT). Kinematic, kinetic, and video data were collected during the steps preceding a turn task. Variables of interest included dynamic stability (maximum mediolateral (ML), minimum ML, and ML range of the center of mass (COM)-base of support (BOS) relationship) and turning performance (gait velocity and step count). There was a statistically significant increase in maximum ML COM-BOS distance (week 4 [0.1298 m?±?0.054] compared to week 0 [0.1069 m?±?0.050] p = .0076), and a significant decrease in step count (week 0-F [5.52 steps ± 1.08] to week 0-FO [5.23 steps ± 0.87] p = .0296) and (week 4-FO [5.24 steps ± 1.31] to week 4–FOT [4.67 steps ± 0.76] p = .0004). Textured foot orthotics modified dynamic stability and turning performance in Parkinson’s disease individuals completing a 180° degree turn. These preliminary results support this potential treatment option for rehabilitation professionals treating Parkinson’s disease. 相似文献

The coefficients of internal consistency and retest reliability had been rarely investigated within the methodology of dream content analysis. Analyzing a dream series of elderly, healthy persons obtained from weekly telephone interviews, the internal consistency of a series of 20 dreams and retests after 4 or 22 weeks, respectively, had been computed. The findings indicate that dream recall and dream length are quite stable, but dream characteristics such as bizarreness and emotional tone underlie large intraindividual fluctuations. In order to obtain reliable measures for these variables which will be important for correlational studies, including waking-life trait measures, one has to obtain as many dreams as possible (about 20) in a very short time period. Further research is needed to extend the present findings to diary dreams and laboratory dreams. 相似文献

This study demonstrates how challenge stressor, a job demand that can bring potential gains for employees, influences voice, a change-oriented behaviour challenging the status quo. Specifically, we develop and test an inverted U-shaped relationship that integrates social exchange theory and the framework of resource allocation. Using data collected from 204 employees in Eastern China, we find that the U-shaped relationship between challenge stressor and voice is only emerged at low levels of leader–member exchange. At high levels of leader–member exchange the relationship between challenge stressor and voice is U-shaped. Furthermore, the interactive effect of challenge stressor and leader–member exchange on voice behaviour is mediated by organisation-based self-esteem. The findings of this study have important implications for stress and voice literature. 相似文献
