Individual variations in the way people respond to sensory stimuli can sometimes lead to maladaptive representations of the world. Indeed, sensory responsiveness profiles were found to be associated with mood symptoms such as depression and anxiety. The goal of the current study was to investigate whether attachment orientations can account for the relationship between sensory responsiveness profiles and anxiety symptoms. Participants (N = 194) completed a battery of questionnaires assessing sensory responsiveness profiles, attachment orientations, and anxiety symptoms. As expected, various associations between sensory responsiveness profiles and anxiety symptoms were accounted for by attachment anxiety and avoidance. We suggest a possible causal path, in which early‐developing sensory responsiveness profiles lead to attachment insecurities, which in turn may lead to mood symptoms such as anxiety. 相似文献

The present study examined the relationships between different types of social and cognitive activities and different types of episodic and semantic memory. A total of 794 adult men and women from five age cohorts (aged 65–85 at baseline), participating in the longitudinal Betula project on ageing, memory, and health, were included in the study. The participants were studied over 10 years (1995–2005) in three waves. Recognition and recall were used as episodic memory tasks, and knowledge and verbal fluency as semantic memory tasks. The results, after controlling for age, gender, education, and some diseases, including heart disease and hypertension, as covariates, showed unidirectional effects of social activity on episodic memory on all test occasions (β = .10). Also, episodic memory predicted change in cognitive activity for all test waves (β = .21–.22). Findings suggest that social activity can be seen as protective factor against memory decline. It also seems that episodic memory performance is a predictor of cognitive activity in old people. However, the opposite direction does not hold true. 相似文献

Estimation of the predictive power of the model in mixed‐effects meta‐regression: A simulation study
José Antonio López‐López Fulgencio Marín‐Martínez Julio Sánchez‐Meca Wim Van den Noortgate Wolfgang Viechtbauer 《The British journal of mathematical and statistical psychology》2014,67(1):30-48
Several methods are available to estimate the total and residual amount of heterogeneity in meta‐analysis, leading to different alternatives when estimating the predictive power in mixed‐effects meta‐regression models using the formula proposed by Raudenbush (1994, 2009). In this paper, a simulation study was conducted to compare the performance of seven estimators of these parameters under various realistic scenarios in psychology and related fields. Our results suggest that the number of studies (k) exerts the most important influence on the accuracy of the results, and that precise estimates of the heterogeneity variances and the model predictive power can only be expected with at least 20 and 40 studies, respectively. Increases in the average within‐study sample size () also improved the results for all estimators. Some differences among the accuracy of the estimators were observed, especially under adverse (small k and ) conditions, while the results for the different methods tended to convergence for more optimal scenarios. 相似文献

For one‐way fixed effects ANOVA, it is well known that the conventional F test of the equality of means is not robust to unequal variances, and numerous methods have been proposed for dealing with heteroscedasticity. On the basis of extensive empirical evidence of Type I error control and power performance, Welch's procedure is frequently recommended as the major alternative to the ANOVA F test under variance heterogeneity. To enhance its practical usefulness, this paper considers an important aspect of Welch's method in determining the sample size necessary to achieve a given power. Simulation studies are conducted to compare two approximate power functions of Welch's test for their accuracy in sample size calculations over a wide variety of model configurations with heteroscedastic structures. The numerical investigations show that Levy's (1978a) approach is clearly more accurate than the formula of Luh and Guo (2011) for the range of model specifications considered here. Accordingly, computer programs are provided to implement the technique recommended by Levy for power calculation and sample size determination within the context of the one‐way heteroscedastic ANOVA model. 相似文献

The family of (non‐parametric, fixed‐step‐size) adaptive methods, also known as ‘up–down’ or ‘staircase’ methods, has been used extensively in psychophysical studies for threshold estimation. Extensions of adaptive methods to non‐binary responses have also been proposed. An example is the three‐category weighted up–down (WUD) method (Kaernbach, 2001) and its four‐category extension (Klein, 2001). Such an extension, however, is somewhat restricted, and in this paper we discuss its limitations. To facilitate the discussion, we characterize the extension of WUD by an algorithm that incorporates response confidence into a family of adaptive methods. This algorithm can also be applied to two other adaptive methods, namely Derman's up–down method and the biased‐coin design, which are suitable for estimating any threshold quantiles. We then discuss via simulations of the above three methods the limitations of the algorithm. To illustrate, we conduct a small scale of experiment using the extended WUD under different response confidence formats to evaluate the consistency of threshold estimation. 相似文献

Earlier studies have shown that feelings of guilt appear to be involved in the burnout process. However, the exact nature of the relationship between burnout, feelings of guilt, and tobacco and alcohol use is unclear. The purpose of this study was to analyze the role of feelings of guilt in the relationship between burnout and the consumption of tobacco and alcohol. Role conflict, Role clarity, and Feedback were included as predictors of burnout. The sample of this cross‐sectional study consisted of 260 Chilean administration and customer service workers. Hypotheses were tested using a path model. The hypothesized model (i.e., Indolence to guilt to tobacco/alcohol use) showed an adequate data fit, including a mediator role of feelings of guilt in the relationship between burnout and alcohol use. The results of this study recommending taking into consideration the evaluation of feelings of guilt as a symptom of burnout in order to develop a more reliable diagnosis of burnout syndrome and its consequences. 相似文献

Philosophers frequently defend definitions by appealing to intuitions and contemporary folk classificatory norms. I raise methodological concerns that undermine some of these defenses. Focusing on Andrew Kania's recent definition of music, I argue that the way in which it has been developed leads to problems, and I show that a number of other definitions of interest to philosophers of art (and others) run into similar problems. 相似文献

Two studies examined how the effect of dependency and emotions on the dynamics of relationship conflict differs between men and women. In Study 1, 96 women and 67 men were presented with conflict situations that might occur in their relationship; the probability of aggression, anger, and dependency was measured. Results showed that anger mediated the relationship between dependency and the intention to use aggression, in men, but not in women. In Study 2, 95 women and 65 men wrote about a conflict situation that they had experienced with their partner; loyalty, guilt, and dependency were measured. Results showed that dependency predicted loyalty among women, and that this effect was mediated by guilt. 相似文献
