Motor influences on the mental transformation of body parts have been observed in both children and adults. Previous findings indicated that these influences were more pronounced in children than in adults, suggesting a stronger link between motor processes and imagery in children. The present series of two experiments casts doubt on the general validity of such an interpretation. Kindergartners' (aged 5–6 years), first graders' (aged 7 years), and adults' performance in the mental rotation of pictures of body parts was monitored for influences of internal representations of motor constraints (motor effect). In both experiments, evidence for mental rotation was obtained for each group. Unexpectedly, kindergarten boys made significantly more errors than kindergarten girls. A motor effect was only found in the second experiment, where it was least pronounced in the youngest age group. Our results suggest that mental transformations of body parts do not necessarily involve motor processes and that embodiment may become stronger with development rather than weaker with certain tasks. 相似文献

Hand hygiene in wound care by health care providers (HCPs) is a key principle in treating hospitalized patients with diabetic foot infections. This study aimed to estimate the extent to which patients with type-2-diabetes (T2D) intend to speak up for HCPs’ hand hygiene during inpatient foot treatment, test whether this motivation increases given the hospital would invite patients to speak up, and identify associations with socio-demographics, knowledge of hand hygiene requirements, and diabetes-related factors. A questionnaire-survey was conducted in eight diabetes outpatient centres in Lower Saxony/Germany. Intentions to speak up (without and with institutional encouragement) and knowledge about hand hygiene during foot-care were assessed. Analyses of variance were conducted, partly as repeated measures-models with intention-items as within-subject factor. N = 473 patients participated (response = 77.4%). N = 177 (41%) strongly intended to speak up. Institutional encouragement was associated with an increased rate of strong (54% vs. 41%; p < .001) and higher mean intention (M = 3.9 vs. 3.4 with vs. without encouragement [5-point-scales]; F(1, 434)?=?41.5, p < .001). In patients without diabetic foot syndrome, this effect was limited to those with at least medium school education (F(2, 292)?=?4.4, p = .013) and knowledge on HCPs’ hand hygiene (F(2, 294)?=?3.1, p = .047). In conclusion, a majority of T2D-patients in diabetes outpatient centres intend to speak for HCPs’ hand hygiene in inpatient foot treatment, and are receptive to institutional encouragement. However, this presupposes at least medium education and knowledge about hand hygiene, emphasizing that patient empowerment begins with knowledge. 相似文献

The scientific study of happiness requires accurate measurement of the construct that satisfies assumptions of parametric statistics and thus allows both researchers and clinicians to make reliable and valid comparisons with the relevant data sources. The 29-item Oxford Happiness Questionnaire (OHQ) is a widely-used scale for assessment of personal happiness. While its psychometric properties are acknowledged to be acceptable, it presents scores on an ordinal scale and may thus not discriminate precisely between individual happiness levels. The current study aimed to improve precision and item functioning of the OHQ by applying Rasch analysis to a sample of 281 participants. To correct disordered thresholds items were rescored in a uniform fashion. Four items displayed poor relationships with the latent trait of happiness and were removed. Best fit to the unidimensional Rasch model was achieved after locally dependent items were combined into subtests and adjusted for personal differences. Using the ordinal-to-interval conversion tables published here, ordinal OHQ scores can now be transformed to interval level data and thus subjected to parametric statistical analysis without violating fundamental assumptions. The precision of the instrument can be improved significantly by these minor modifications without the need to modify the original response format. 相似文献

Social media technologies offer several features that allow users to monitor other people’s opinions on public issues. Initial research showed that user-generated content can shape recipients’ perceptions of the majority opinion on societal problems. Still, it remains largely unexplored under which circumstances people gauge other users’ opinions through social media and whether perceived opinion climates affect people’s opinions and communication behavior in these environments. Results of a two-session experiment revealed that people’s fear of isolation sharpens their attention toward user-generated comments on Facebook which, in turn, affect recipients’ public opinion perceptions. The latter influenced subjects’ opinions and their willingness to participate in social media discussions. These findings are discussed in light of the spiral of silence theory and the social projection hypothesis. 相似文献

We aimed at using simple judgments of event segmentation to reveal cognitive problems in workers with intellectual disability regarding their assembly performance. We investigated event perception and assembly performance in 32 workers (mean IQ = 64.4). First, we assessed their ability to segment activity into meaningful events. The task involved segmenting four videos in coarse and fine events. We assessed event segmentation performance and compared it to 30 controls (IQ > 100). The workers detected fewer event boundaries than controls. A subgroup of the workers (12 of 32) defined more event boundaries in the coarse than the fine condition, indicating misconception of higher‐ and lower‐level content. The remaining 20 workers showed diminished hierarchical alignment compared to controls. Second, workers executed a Lego task. Better event segmentation performance was associated with enhanced assembly performance. These results suggest that the event segmentation task can serve as a diagnostic assessment for cognitive potential.Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

Studies on prospective memory (PM) development in adolescents point to age-related increases through to adulthood. The goal of the present study was to examine whether instructing adolescents to engage in an episodic prospection of themselves executing future actions (i.e., future thinking) when forming an intention would improve their PM performance and reduce age-related differences. Further, we set out to explore whether future thinking instructions result in stronger memory traces and/or stronger cue–context associations by evaluating retrospective memory for the PM cues after task completion and monitoring costs during PM task processing. Adolescents and young adults were allocated to either the future thinking, repeated-encoding or standard condition. As expected, adolescents had fewer correct PM responses than young adults. Across age groups, PM performance in the standard condition was lower than in the other encoding conditions. Importantly, the results indicate a significant interaction of age by encoding condition. While adolescents benefited most from future thinking instructions, young adults performed best in the repeated-encoding condition. The results also indicate that the beneficial effects of future thinking may result from deeper intention-encoding through the simulation of future task performance. 相似文献

Socioanalytic theory postulates that job performance ratings are predicted by basic social motives moderated by social competency. The two motives are the motive to get along with others and the motive to achieve status and power. The present two-study investigation assessed these motives as work values and collected supervisors' job performance and promotability assessments. Social competency was assessed as political skill at work. The results provided strong and consistent support for the hypotheses, thus providing a more direct test of socioanalytic theory and extending it to demonstrate effects beyond overall job performance ratings on contextual performance and promotability assessments. Contributions and implications of these results, strengths and limitations, directions for future research, and practical implications are discussed. 相似文献

To ensure successful implementation of genetic screening and counselling according to patients best interests, the attitudes and motives of the public are important to consider. The aim of this study was to apply a theoretical framework in order to investigate which individual and disease characteristics might facilitate the uptake of genetic testing. A questionnaire using an extended version of the Theory of Planned Behaviour was developed to assess the predictive value of affective and cognitive expected outcomes, subjective norms, perceived control and uncertainty avoidance on the intention to undergo genetic testing. In addition to these individual characteristics, the predictive power of two disease characteristics was investigated by systematically varying the diseases fatality and penetrance (i.e. the probability of getting ill in case one is a mutation carrier). This resulted in four versions of the questionnaire which was mailed to a random sample of 2400 Norwegians. Results showed genetic test interest to be quite high, and to vary depending on the characteristics of the disease, with participants preferring tests for highly penetrant diseases. The most important individual predictor was uncertainty avoidance. 相似文献

Tic disorders are heterogeneous, with symptoms varying widely both within and across patients. Exploration of symptom clusters
may aid in the identification of symptom dimensions of empirical and treatment import. This article presents the results of
two studies investigating tic symptom clusters using a sample of 99 youth (M age = 10.7, 81% male, 77% Caucasian) diagnosed
with a primary tic disorder (Tourette’s disorder or chronic tic disorder), across two university-based outpatient clinics
specializing in tic and related disorders. In Study 1, a cluster analysis of the Yale Global Tic Severity Scale (YGTSS) identified
four symptom dimensions: predominantly complex tics; simple head/face tics; simple body tics; and simple vocal/facial tics.
In Study 2, these clusters were shown to be differentially associated with demographic and clinical characteristics. Findings
lend support to prior research on tic phenomenology, help to organize treatment goals, and suggest symptom dimensions of tic
disorders for further evaluation. 相似文献

Works councillors are elected representatives of employees in German companies. It is their job to protect and bargain the interests of the employees with the company. We investigated the impact of 558 works councillors' individual political skill on their career success, where career ascendancy is based on success in upward elections and not on appointments by supervisors. The participants were from core German industries mostly working in large companies. We found that the stronger works councillors' political skill the more successful they were in their career still after controlling for sex, age, and union membership. Implications and limitations of the study and consequences for future research are discussed. 相似文献
