Three-dimensional gait analysis is the gold standard for gait-assessment in patients with stroke. This technique is commonly used to assess the effect of treatment on gait parameters. In clinical practice, three gait analyses are usually carried out (baseline, after treatment and follow-up), the objectives were to define the reproducibility and the Minimum Detectable Change (MDC) for gait parameters in stance and swing measured using 3D-gait analysis, and to assess changes in MDC across three repeated 3D-gait analyses. Three gait analyses (V1, V2 and V3) were performed at 7-day intervals in twenty-six patients with chronic stroke. Kinematic data (in the sagittal plane, during swing and stance) and spatiotemporal data were evaluated for the paretic limb. Reliability was tested using repeated measures ANOVA with a Tukey post hoc test, and the MDC values were calculated for each parameter. Only the range of hip motion during swing changed significantly between V1 and V2, but no other kinematic parameters changed. No significant differences were observed for the spatiotemporal parameters. MDC values were always higher during the V1vsV2 comparison for both kinematic and spatiotemporal parameters. This is the first study to evaluate the MDC for kinematic and spatiotemporal parameters during stance and swing. Reliability of kinematic and spatiotemporal data across sessions was very good over the three sessions. MDC values were the lowest between V2 and V3 for most parameters. Use of the MDC will allow clinicians to more accurately determine the effect of treatments. 相似文献

ABSTRACTThe Francis Scale of Attitude toward Christianity was designed in the mid-1970s to assess individual differences in attitude through childhood, adolescence, and adulthood from the age of 8?years upwards. This study examines the internal consistency reliability, factor structure, and construct validity of the instrument 40?years later among 1511 year 4 students (8–9 years), 1544 year 5 students (9–10 years), and 1526 year 6 students (10–11 years) in Wales attending Church in Wales voluntary aided and voluntary controlled primary schools. The data support the internal consistency reliability and construct validity of the instrument among the age range and commend the instrument for continued use in research. 相似文献

To probe the inconsistent link between education and attitude change toward minority social groups, we conducted a field study that focused on audience characteristics and education about lesbian, gay, and transgender (LGT) targets. Participants enrolled in a sexuality course were compared to those in a neurology course, both taught by the same professor. Multiple regression analyses predicted attitude change toward LGT targets from social dominance orientation (SDO), right-wing authoritarianism (RWA), ratings of professor’s characteristics, SDO by course interaction, and RWA by course interaction. Only the SDO by course interaction significantly predicted attitude change. Simple slopes analyses indicated that high-SDO participants in the sexuality course showed the most positive attitude change. These findings suggest that education may reduce prejudice for certain audience characteristics. 相似文献

People often reason proportionally, perceiving fixed outcomes as larger or smaller depending upon the reference condition. Thus, for policies affecting individuals, presenting data as percentages rather than frequencies can alter perceived effects on high versus low base rate group members, even though identical numbers of individuals in each group are affected. Such numerical framing effects were explored through a case analysis of public debates over race-conscious selection policies and through experimental manipulations employing a race-conscious university admissions scenario. Undergraduates (N = 193) received data reporting the expected impact on black and white student enrollment resulting from a university shift to race-neutral admissions. Compared to those encountering percentages or proportions, participants receiving identical information expressed as frequencies revealed a predicted greater preference for race-neutral or “race blind” admissions. Structural equation analysis supported a model in which perceived impact and fairness mediated the relationship between format and endorsement of race-neutral admissions. 相似文献

We tested the hypothesis that Faith in Intuition (FI) would moderate implicit–explicit attitude relationship strength for attitudes formed via associative processes, but not propositional processes. Experiments 1 and 2 demonstrated that FI moderated I–E relationship strength for attitudes formed via evaluative conditioning. High FI people had stronger I–E correlations. Experiment 2 showed that FI did not moderate I–E relationship strength for attitudes formed via propositional reasoning. Those low in Need for Cognition (NC), however, showed stronger I–E correlations than those high in NC. The importance of considering trait variables in combination with the method of attitude formation is discussed. 相似文献

Statistical properties in the visual environment can be used to improve performance on visual working memory (VWM) tasks. The current study examined the ability to incidentally learn that a change is more likely to occur to a particular feature dimension (shape, color, or location) and use this information to improve change detection performance for that dimension (the change probability effect). Participants completed a change detection task in which one change type was more probable than others. Change probability effects were found for color and shape changes, but not location changes, and intentional strategies did not improve the effect. Furthermore, the change probability effect developed and adapted to new probability information quickly. Finally, in some conditions, an improvement in change detection performance for a probable change led to an impairment in change detection for improbable changes. 相似文献

Perceivers generally show a poor ability to detect changes, a condition referred to as “Change Blindness” (CB). They are, in addition, “blind to their own blindness”. A common explanation of this “Change Blindness Blindness” (CBB) is that it derives from an inadequate, “photographical” folk-theory about perception. This explanation, however, does not account for intra-individual variations of CBB across trials. Our study aims to explore an alternative theory, according to which participants base their self-evaluations on two activity-dependent cues, namely search time and perceived success in prior trials. These cues were found to influence self-evaluation in two orthogonal ways: success-feedback influenced self-evaluation in a global, contextual way, presumably by recalibrating the norm of adequacy for the task. Search time influenced it in a local way, predicting the success of a given trial from its duration. 相似文献

Visual attentional processing was examined in adult meditators and non-meditators on behavioral measures of change blindness, concentration, perspective-shifting, selective attention, and sustained inattentional blindness. Results showed that meditators (1) noticed more changes in flickering scenes and noticed them more quickly, (2) counted more accurately in a challenging concentration task, (3) identified a greater number of alternative perspectives in multiple perspectives images, and (4) showed less interference from invalid cues in a visual selective attention task, but (5) did not differ on a measure of sustained inattentional blindness. Together, results show that regular meditation is associated with more accurate, efficient, and flexible visual attentional processing across diverse tasks that have high face validity outside of the laboratory. Furthermore, effects were assessed in a context separate from actual meditation practice, suggesting that meditators’ better visual attention is not just immediate, but extends to contexts separate from meditation practice. 相似文献

Three experiments investigate expertise as a moderator of the relationship between implicit and explicit attitude measures. Prior research suggests that greater expertise leads to stronger implicit–explicit relations; however, a cognitive view of expertise can also predict a weaker implicit–explicit relation. Our framework helps to resolve that seeming contradiction on the basis of the availability/accessibility of attributes versus attitudes in explicit attitude measures. We show that object specificity and contextual factors (e.g., instructions and prior evaluations in a survey) differentially affect the availability/accessibility of global attitudes and attribute information for novices versus experts, thus determining how expertise moderates the implicit–explicit relation. 相似文献
