Ability to recognize a runner as a teammate from only a brief visual exposure is suggested from research on gait recognition with point-light displays and has particular importance for ball-passing in sports. 15 touch football players of mean age 20 yr. (SD=0.7), on two teams of 7 wk. standing, observed 31 400-msec, video clips of running individuals whose familiarity varied from high to low. These were their teammates, players from the other team, or nonfootball players. After viewing each clip, participants rated their certainty that each running player was a teammate. Despite the brevity of the visual display, overall performance at discriminating teammates from other runners was significantly better than chance, and accuracy did not differ between colour or black-and-white formats. Recognition of teammates was better if familiar nonteammates were removed from the set of analyzed clips and worse if unfamiliar nonplayers were removed. 相似文献

There is a need to evaluate the effectiveness of stuttering treatment programs delivered in domestic and international contexts and to determine if treatment delivered internationally is culturally sensitive. Evaluation of the effectiveness of the ISTAR Comprehensive Stuttering Program (CSP) within and across client groups from the Netherlands and Canada revealed generally positive results. At 2 years post-treatment both groups were maintaining statistically significant reductions in stuttering frequency and improvements in attitudes, confidence, and perceptions as measured by the Revised Communication Attitude Inventory (S24), Perceptions of Stuttering Inventory (PSI), and the approach scale of the Self-Efficacy Scaling by Adult Stutterers (SESAS). Data pooled across the groups on these measures gave evidence of a global treatment effect with standardized effect sizes ranging from typical to larger than typical in the behavioural sciences. Only two differences between the groups emerged: differences in speech rate and perception of self. Given that these groups represent two distinct cultures, differences were discussed in terms of whether they could be due to cultural, methodological, or other variables. Overall, results suggest that, the CSP appears to be similarly effective in both cultures and thus, sufficiently sensitive to the culture of Dutch adults who stutter.
Educational objectives: The reader will be able to (a) describe a methodology that can be used in a clinical setting to evaluate the long-term effectiveness of stuttering treatment with adults, (b) describe some of the challenges in developing a model of clinically meaningful outcome, (c) explain the rationale for the need for cross-cultural investigations of treatment outcome, and (d) summarize speech and self-report results of the cross-cultural evaluation of an integrated stuttering treatment program. 相似文献

At the heart of evidence-based practice in stuttering treatment are four issues: (1) the collection of data to inform treatment; (2) the long standing concern with maintenance of treatment gains; (3) the need to demonstrate accountability to clients, payers and our profession as service providers; and (4) the desire to advance theoretical knowledge. This article addresses the first three of these issues from a practical point of view, illustrating how data collection for stuttering treatment outcome research in a clinical setting is intimately blended with that required for clinical purposes and providing an example of a process of evaluating data for clinical and research purposes. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to (1) differentiate between treatment outcome and treatment efficacy research, (2) describe models for integrating data collection for treatment outcome and clinical purposes, and (3) utilize guidelines for treatment efficacy that are applicable to outcome research to evaluate data for use in treatment outcome studies and to design outcome studies. 相似文献

Researchers in a growing number of areas (including cognitive development, aging, and neuropsychology) use Brinley plots to compare the processing speed of different groups. Ratcliff, Spieler, and McKoon (2000) argued that a Brinley plot is a quantile-quantile (Q-Q) plot and that therefore Brinley plot regression slopes measure standard deviation ratios rather than relative speed of processing. We show that this argument is incorrect. Brinley plots, by definition, are not Q-Q plots; the former are based on unranked data and the latter are based on ranked data. Furthermore, the relationship between standard deviation ratios and slopes is a general property of regression lines and has no implications for the use of Brinley plot regression slopes as processing speed measures. We also show that the relative speed interpretation of Brinley plot slopes is strongly supported by converging evidence from a metaanalysis of visual search, mental rotation, and memory scanning in young and older adults. As to Ratcliff et al.'s hypothesis that age differences in response time are attributable to greater cautiousness on the part of the elderly, rather than true processing speed differences, this hypothesis has been extensively tested in previous studies and found wanting. 相似文献

Patients desire to have information about health-related behaviors (e.g., exercise) provided to them by their health care provider. Outcomes of clinical trials in physical activity counseling are modest at best and therefore, the degree of effectiveness of physical activity counseling in the primary care setting remains unclear. We describe what may be considered a real-world example of behavior change counseling aimed at primary or secondary risk factor identification and modification for CHD in women. We examined rates of baseline and follow-up physical activity in our sample of midlife Caucasian and African American women (N = 227) participating in a hospital-based CHD-risk screening. Baseline physical activity levels and rates of return for follow-up appointments were quite low with only negligible achievement of behavior change recommendations. In light of these findings, the potential role of behavioral medicine in training and collaboration with health care providers in primary care behavior counseling is discussed. 相似文献

We investigated the reliability and validity of a video-based method of measuring the magnitude of children’s emotion-modulated
startle response when electromyographic (EMG) measurement is not feasible. Thirty-one children between the ages of 4 and 7
years were videotaped while watching short video clips designed to elicit happiness or fear. Embedded in the audio track of
the video clips were acoustic startle probes. A coding system was developed to quantify from the video record the strength
of the eye-blink startle response to the probes. EMG measurement of the eye blink was obtained simultaneously. Intercoder
reliability for the video coding was high (Cohen’sκ = .90). The average within-subjects probe-by-probe correlation between the EMG- and video-based methods was .84. Group-level
correlations between the methods were also strong, and there was some evidence of emotion modulation of the startle response
with both the EMG- and the video-derived data. Although the video method cannot be used to assess the latency, probability,
or duration of startle blinks, the findings indicate that it can serve as a valid proxy of EMG in the assessment of the magnitude
of emotion-modulated startle in studies of children conducted outside of a laboratory setting, where traditional psychophysiological
methods are not feasible. 相似文献

The objective of the study was to investigate how self-enhancing evaluations, obtained via positive social comparisons and reflected appraisals, were related to mental health in a later life transition. The sample consisted of 266 women who were interviewed once before and 3 times after the experience of community relocation. Results extended prior findings suggesting the dynamic impact of self-enhancing evaluative processes on psychological well-being and depressive symptoms. Additional analyses showed evidence for reverse causality, that is, that mental health also influenced self-evaluative processes. This study underscores the significance of holding a positive view of self vis-à-vis others in negotiating life challenges as well as the reciprocal influence of well-being on social self-evaluative processes. 相似文献

Three experiments tested whether the relationship between age differences in temporal and item memory depends on the degree to which the item memory measure relies on memory for context. The authors predicted a stronger relationship of temporal memory to free recall than to recognition memory. Results showed that age differences in temporal memory could be eliminated after controlling for free recall but not recognition memory performance. Under some conditions recognition memory accounted for a significant portion of age-related variance in temporal memory. These results challenge past research that has interpreted age differences in temporal and item memory as independent and suggest that a generalized decline in context memory may underlie reduced performance in older adults on all types of memory tests. 相似文献

Two studies investigated overweight in African American girls. First, African American adolescent girls (BMI was ≥ 85th percentile) and their mothers participated in focus groups addressing weight and eating. Although mothers and daughters shared some similar views on these issues, there were important discrepancies, with mothers expressing greater doubt about the potential success of a healthy weight program. The second study evaluated baseline data from 39 African American girls participating in a weight management program; mothers' reports were also analyzed. In both studies, adolescents reported significant teasing, and in the second study, teasing was inversely associated with social quality of life (β=.55, t=3.01, p=.007). Motivation to participate was positively associated with teasing (r=.50, p < .01). Self-esteem was inversely related to positive health habits (all p < .05). Mothers who viewed their daughters as having higher self-esteem were less concerned about their daughters' weight. Differences in mothers' and daughters' perceptions highlight the importance of a family approach in pediatric overweight interventions. Results provide evidence that overweight African American girls face significant weight stigmatization and suggest areas to target regarding intervention implementation.
