As the workforce ages it becomes important to examine if there is misperception of creativity and age in work contexts. A laboratory experiment examined perceptions of the creativity of a team with both young and old workers and of a team composed entirely of young workers. Scripted videos portrayed such teams engaged in designing an outdoor advertising campaign. Altogether, 220 participants were randomly assigned to watch one of the video clips and complete a structured questionnaire. No significant differences were observed in the perceptions of the two teams' performance or of the quality of the resulting advertising proposal. In general, there was also no significant difference in the individual characteristics attributed to the four characters on the teams. However, participants aged 35 or above evaluated both teams and all four characters more favorably than participants aged 20–34. 相似文献

Although dispositional optimism serves as a resource for psychological and physical well-being, very little research has explored how to promote child dispositional optimism within the family context. The authors evaluated paternal emotional expressiveness within the family as a mediator of the association between father's and child's dispositional optimism. Participants were 422 father (M age = 44.97 years, SD = 4.21 years)–child (M age = 11.75 years, SD = 0.77 years) dyads in South Korea. Results showed that fathers’ dispositional optimism was positively linked to their expressiveness, which in turn was positively linked to their children's dispositional optimism. No significant gender or socioeconomic status differences were found. The findings have important implications for future research and for preventive interventions. 相似文献

AbstractThis 1-year longitudinal study examined the bidirectional mediating role of loneliness in the association between shyness and generalized pathological Internet use (GPIU) in a sample of 291 Chinese university students (143 men, mean age =?19.07?years). A fully cross-lagged panel design was used in which shyness, loneliness, and GPIU were assessed at 3 time points separated by 6-month intervals (named T1, T2, and T3). The results indicated that relationships among shyness, loneliness, and GPIU were dynamic and bidirectional. Specifically, T1 shyness positively predicted increased T2 loneliness, T2 shyness positively predicted increased T3 loneliness, and T2 loneliness positively predicted increased T3 shyness. Additionally, T1 GPIU positively predicted increased T2 loneliness, T2 GPIU positively predicted increased T3 loneliness, and T2 loneliness positively predicted increased T3 GPIU. Loneliness was found to play a bidirectional mediating role in the association between shyness and GPIU. Specifically, T1 shyness and T3 GPIU were mediated through increased loneliness at T2, and T1 GPIU and T3 shyness were mediated through increased loneliness at T2. Furthermore, relationships among shyness, loneliness, and GPIU were the same across the 2 groups, with the strength of relationships being stronger for men. 相似文献

This article reviews a wide range of risk factors associated with the development of conduct problems in children, with a particular focus on the influence of time spent engaged in different types of activities. The review reveals the behavioral benefits to children and adolescents of participation in activities with physical, social, and restful properties and those that can be described as structured. Further highlighted is the need for parents and occupational therapists to be aware of children's time use and daily activity participation, and the potential for these activities to be harnessed to facilitate positive behavioral outcomes for children. 相似文献

The purpose of this study was to investigate the differences of knee concentric and eccentric strength and impact related knee biomechanics between jumpers and non-jumpers during step-off landing tasks. Ten male college swimming athletes (non-jumpers) and 10 track and volleyball athletes (jumpers) were recruited to participate in two test sessions: a muscle strength testing session of concentric and eccentric extension for dominant knee joint at 60 °/s and 180 °/s and a landing testing session. The participants performed five trials of step-off landing in each of four conditions: soft and stiff landing from 0.4 m and 0.6 m landing heights. The three-dimensional kinematics and ground reaction force were recorded simultaneously during step-off landing conditions. The results showed that the jumpers had significantly greater peak knee eccentric extension and concentric flexion torques compared to the non-jumpers. No significant group effects were found for peak vertical ground reaction force and knee range of motion during landing. The jumpers had significantly greater knee contact flexion angle, maximum knee flexion angle and initial knee extension moment compared to the non-jumpers. These results suggest that these athletes adopted a favorable impact attenuation strategy that is related to the greater knee eccentric muscle strength and training. 相似文献

The current research examined the moderating role of employees' need for cognitive closure in the relationship between their perceived person–job fit and their work-related attitudes. In Study 1, a survey was conducted among 176 Chinese employees from various organizations, and the results confirmed that both demand–ability fit and need–supply fit were positively related to employees' job satisfaction; moreover, these relations were stronger among people with higher need for closure than those scoring lower in need for closure. In Study 2, a survey was conducted among 242 employees from a Chinese city government, and the results replicated the findings of Study 1, but also found that need for closure moderated the relation between demand–ability fit and turnover intention. These results have important implications for research in organizational psychology and human resource management. 相似文献

Two studies investigated whether one dimension of action–state orientation, namely, persistence-volatility, would moderate the effect of implementation intentions on goal progress. Results from Study 1 indicated that spontaneous implementation intentions predicted goal progress 2 weeks later only among participants who scored high on persistence. In Study 2, participants were randomly allocated to an implementation intentions group and a control group. Results indicated that persistence was positively associated with goal progress among participants in the implementation intentions group but not among those in the control group. Theoretical and practical implications of these findings were discussed. 相似文献

The Multilevel Latent Class Model (MLCM) proposed by Vermunt (2003) has been shown to be an excellent framework for analyzing nested data with assumed discrete latent constructs. The nonparametric version of MLCM assumes 2 levels of discrete latent components to describe the dependency observed in data. Model selection is an important step in any statistical modeling. The task of model selection for MLCM amounts to the decision on the number of discrete latent components at both higher and lower levels and is more challenging than standard Latent Class Models. In this article, simulation studies were conducted to systematically examine the effects of sample sizes, clusters/classes distinctness, and the number of latent clusters and classes on the performance of various information criteria in recovering the true latent structure. Results of the simulation studies are summarized and presented. The final section presents the remarks and recommendations about the simultaneous decision regarding the number of latent classes and clusters when applying MLCMs to analyze empirical data. 相似文献

The present study examined the developmental issue of cognitive factors that explain Chinese literacy. Phonological awareness, rapid automatized naming, short-term memory, orthographic awareness and morphological awareness and two literacy tasks (character naming and reading fluency) were administered to 408 second-graders, 428 fourth-graders and 496 six-graders. Results from linear regression analysis and path analysis model showed that the five reading-related cognitive constructs explained unique variances in character naming. Second, character naming is primary for reading fluency after controlling other cognitive constructs; third, the relation between the cognitive factors and literacy changes significantly as a function of reading skills. Results give a clear direction to understanding Chinese reading development. 相似文献

It is still unclear how attentional control influences stimulus processing. We investigated this issue in four Stroop task experiments utilizing a pretest–training–posttest design. Subjects were given extensive training on the Stroop task using typical incongruent Stroop trials. The rates of color naming and word reading, which reflect the efficiency of stimulus processing, were assessed in pretest and posttest. The difference in rates between posttests and pretests reflects the influence of attentional control, acquired during the training phase, on stimulus processing. In Experiment 1, members of color category were used in the training phase; in Experiment 2, members of color category were used, but not in the training phase; in Experiment 3, they were neither in the color category nor were they used in the training. The results consistently showed that the suppression of word reading and the enhancement of color naming were developed in the training phases and they were not due to general training of color-naming task without conflict but to color-naming training with Stroop conflict (Experiment 4). More importantly, both suppression and enhancement affected the members of color category regardless of whether they were trained or not. The present findings suggest that the influence of attentional control on stimulus processing is category specific. We discuss the implications of the present results in terms of existing research on the locus of attentional control in Stroop tasks. 相似文献
