The Wilcoxon–Mann–Whitney procedure is invariant under monotone transformations but its use as a test of location or shift is said not to be so. It tests location only under the shift model, the assumption of parallel cumulative distribution functions (cdfs). We show that infinitely many monotone transformations of the measured variable produce parallel cdfs, so long as the original cdfs intersect nowhere or everywhere. Thus there are infinitely many effect sizes measured as shifts of medians, invalidating the notion that there is one true shift parameter and thereby rendering any single estimate dubious. Measuring effect size using the probability of superiority alleviates this difficulty. 相似文献

Two studies were conducted to assess appearance-related visual processing mechanisms in populations at risk of disorders characterized by body image disturbance. Using inverted stimuli, Experiment 1 assessed visual processing mechanisms associated with body, face, and house viewing in adolescents. Experiment 2 applied the same protocol to assess appearance-related configural processing in high- and low-risk adolescent women, and women recovering from disorders characterized by body image disturbance. Experiment 1 found evidence for typical configural face and body processing, although adolescent women reported higher levels of body image concern (BIC) and self-objectified to a greater extent than adolescent men. In Experiment 2, typical body inversion effects were seen in the low-risk group, whilst there was some evidence to suggest a disruption to the configural processing of body stimuli in high-risk adolescents and in women recovering from body image disorders. Women in recovery were also quicker to respond to all stimuli, whilst high-risk adolescents took longer to respond to bodies than to other stimuli. Configural face processing was intact in all groups, and effects did not directly relate to BIC or self-objectification. These findings have implications for future research looking to inform early interventions and treatment, suggesting that there could be a tendency to visually process individual body parts at the expense of the whole-body form in women at risk of developing body image disorders, as well as those in recovery. 相似文献

There have been frequent attempts in psychology to reduce the reliance on null hypothesis significance testing (NHST) as the criterion for establishing the importance of results. Many authorities now recommend the reporting of effect sizes (ESs) as a supplement or alternative to NHST. However, there is extensive specialist literature highlighting problems associated with the use and interpretation of ESs. A review of the coverage of ESs in over 100 textbooks on statistical analysis in behavioural science revealed widespread neglect of ESs and the relevant critical issues that have widespread coverage in the more specialist literature. For example, many textbooks claim that ESs should be interpreted as a simple measure of the practical real-world importance of a result despite the fact that ESs are profoundly influenced by features of design and analysis strategy. We seek to highlight areas of misunderstanding about ESs found in the pedagogical literature in the light of the more specialist literature and make recommendations to researchers for the appropriate use and interpretation of ESs. This is critical as statistics textbooks have a crucial role in the education of researchers. 相似文献

AbstractBackground: Transgender individuals belong to one of the most stigmatized groups in society. Although the social stigma of transgender individuals has been examined many times, post transition stigma experiences among transgender individuals have received limited research attention. The aim of this study was to examine experiences with stigmatization among Dutch transgender individuals after their transition.Method: Ten trans women (age: M?=?58.50, SD?=?9.49) and 10 trans men (age: M?=?42.90, SD?=?13.62) participated in face-to-face semistructured interviews. Grounded theory was used to conceptualize and analyze the data. We examined the positive and negative reactions that transgender individuals experienced in the period after their transition. Furthermore, we explored differences between experiences of trans men and trans women. Finally, we examined differences between cisgender men and women regarding their reactions toward transgender individuals.Results: Participants reported improved psychological well-being since transition. However, they still experienced different forms of stigmatization. Trans women appeared to experience stronger social stigma than trans men. Trans women also experienced lower social status after their transition. They mainly experienced negative responses from cisgender men. Participants emphasized the importance of social and peer support.Conclusion: The current study findings demonstrate the presence of stigmatization after transition and argue for psychological aftercare. Social and peer support appeared to be important for coping with stigmatization, and improving the social network of transgender individuals is beneficial. Health providers and researchers are recommended to promote the development of constructive coping skills for transgender individuals with interventions especially targeting trans women. 相似文献

Theory and research on self‐regulation, emotional adjustment, and interpersonal processes focus increasingly on parasympathetic functioning, using measures of vagally mediated heart rate variability (vmHRV) or respiratory sinus arrhythmia (RSA). This review describes models of vmHRV in these areas, and issues in measurement and analysis. We propose a framework organizing theory and research as examining (a) vmHRV as an individual difference or a situational response, and (b) resting, reactive, or recovery levels. Evidence supports interpretation of individual differences in resting vmHRV as a broad biomarker for adaptive functioning, but its specificity and underlying mechanisms require elaboration. Individual differences in vagal reactivity (i.e., trait‐like differences in vmHRV decreases during challenge or stress) are less commonly studied in adults and results are mixed. Many stressors and challenges evoke temporary decreases in vmHRV, and in some research self‐regulatory effort evokes increases. In a smaller literature, positive interpersonal experiences and some restorative processes increase resting vmHRV, whereas depletion of self‐regulatory capacity through related effort decreases it. Greater attention to conceptual distinctions regarding vmHRV constructs and several methodological issues will strengthen future research. Importantly, researchers should exercise caution in equating vmHRV with specific psychosocial constructs, especially in the absence of converging assessments and precise experimental manipulations. 相似文献

ABSTRACT Sequential modulations in symbolic cueing tasks have been attributed to complete versus partial repetition/alternation of stimulus features between consecutive trials. This feature-integration hypothesis is questioned by recent findings and further investigated in the present study. In the first two experiments, when the cueing axes switched between trials, only complete alternation of cue directions and target locations existed. Nevertheless, significant sequence effects were still found in this condition, which did not support the feature-integration hypothesis. Furthermore, although sequence effects were still significant when stimulus identities were manipulated in Experiment 3, it was abolished when different cue categories (gaze and arrow) were presented as cues in Experiment 4. The findings suggest that the integration of stimulus features is not the only source of the sequential effect and some higher level cognitive mechanisms, possibly as described in the task-file or task organization hypotheses, are involved in the sequential modulations of symbolic cueing. 相似文献

ABSTRACT The present study aimed to explore whether the modulation effects of attentional biases toward time information representing immediate rewards and delayed rewards differ between individuals with high and low trait self-control. Forty participants with high trait self-control and 40 with low trait self-control were selected based on their responses to the Chinese version of the self-control scale, and they were asked to complete an intertemporal choice task and dot probe task first and then a cue-target task a week later. The results showed that the participants with low trait self-control were more likely to choose immediate rewards than participants with high trait self-control. Furthermore, facilitated attention and difficulty in attention disengagement toward present-related words were found among participants with low trait self-control with higher frequency than among those with high trait self-control. Finally, facilitated attention toward present-related words moderated the indifference points among the participants with low trait self-control. 相似文献

As the population ages, it is important to understand the factors that contribute to well‐being in the elderly. The purpose of this study is to perform a systematic review and meta‐analysis of research on well‐being among elderly people conducted particularly within the framework of self‐determination theory and, more precisely, to study the relationships among basic psychological need satisfaction, motivation, and well‐being. Therefore, a systematic search of the literature was conducted using the databases PsycINFO, PsycARTICLES, Academic Onefile, MEDLINE, Science Direct, and ERIC to find studies published in English and French. China National Knowledge Infrastructure (CNKI) was used to find studies published in Chinese. Ultimately, 23 studies (mainly from the United States, Canada, and Europe; no studies published in China were found) in the field of aging were used for the systematic analysis, 17 of which were used for the meta‐analysis. The results reported in these publications are relatively congruent with the idea that basic psychological need satisfaction and motivation (autonomous types) are positively associated with positive indicators of well‐being (meaning in life, life satisfaction, positive affect, self‐esteem, etc.) and negatively associated with negative indicators of well‐being (depression, apathy, etc.). 相似文献
