Categorisation salience and ingroup bias: The buffering role of a multicultural ideology

The current work sought to test the moderating role of a multicultural ideology on the relationship between categorisation salience and ingroup bias. Accordingly, in one experimental study, we manipulated categorisation salience and the accessibility of a multicultural ideology, and measured intergroup attitudes. Results show that categorisation salience only leads to ingroup bias when a multiculturalism (MC) ideology is not made salient. Thus, MC ideology attenuates the negative effects of categorisation salience on ingroup bias. These results pertain to social psychology in general showing that the cognitive processes should be construed within the framework of ideological contexts.     

Learning from parents' stories about what works in early intervention

Using a multiple case study approach, this ethnography examined the experiences of parents of children deemed at risk for developmental delays or disabilities who had received early intervention (EI) services (birth to age 3 years) in a large urban location in Western Canada. Participants (11 adult parents and 7 children) were drawn from six families. Methods of data collection included focus groups (FG), face‐to‐face interviews and file reviews. Member check and expert reviews were conducted throughout data collection and data analyses as part of the validation process in this ethnography. Qualitative content analyses followed by thematic analyses highlighted the implementation of family‐centred practices (FCP) as a main theme. Parents identified how EI professionals using FCP embraced collaborative practices. FCP resulted in parents leading the EI process for their children. More specifically, EI professionals shared strategies and information to support parents in gaining a deeper understanding of their children's individual developmental characteristics. Parents expressed how empowering this level of understanding was for them as they learned to articulate what were their children's needs for developmental, health and educational services. Recommendations for future research include inquiring about parents' experiences for families of diverse constellations and/or residing in smaller urban or rural communities.     

The relationship between sensory responsiveness profiles,attachment orientations,and anxiety symptoms

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.     

Examination of the bidirectional influences of leisure activity and memory in old people: A dissociative effect on episodic memory

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.     

Estimation of the predictive power of the model in mixed‐effects meta‐regression: A simulation study

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.     

Sample size determinations for Welch's test in one‐way heteroscedastic ANOVA

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.     

On the limitations of fixed‐step‐size adaptive methods with response confidence

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.     

The mediating role of feelings of guilt in the relationship between burnout and the consumption of tobacco and alcohol

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.
