A sequential exploratory diagnostic model using a Pólya-gamma data augmentation strategy

Cognitive diagnostic models provide a framework for classifying individuals into latent proficiency classes, also known as attribute profiles. Recent research has examined the implementation of a Pólya-gamma data augmentation strategy binary response model using logistic item response functions within a Bayesian Gibbs sampling procedure. In this paper, we propose a sequential exploratory diagnostic model for ordinal response data using a logit-link parameterization at the category level and extend the Pólya-gamma data augmentation strategy to ordinal response processes. A Gibbs sampling procedure is presented for efficient Markov chain Monte Carlo (MCMC) estimation methods. We provide results from a Monte Carlo study for model performance and present an application of the model.     

卫生保健的伦理教学:寻求一种新的教育学

鉴于要使全球性的生命伦理学包括边缘化人群进入主流社会,一个重要方面就是重构教育学.通过这种重构,伦理语境从一代代的医学专业人士或社会/医学研究者中复制出来.我们当前的伦理学教学是哲学的,从理性的观点来看,这不是奇怪的.如果伦理学教学方法本身是家长主义的,这种伦理学教学如何传递文化上的多种声音或真理的相对性?     

Thinking About Thinking About Work: A Meta-Analysis of Off-Job Positive and Negative Work-Related Thoughts

Work is frequently on the minds of employees—even during evenings, weekends, and vacations. The present study is the first comprehensive meta-analysis of off-job work-related thoughts (WRTs; i.e., thoughts employees have about work when they are not at work). We were particularly interested in comparing off-job positive and negative work-related thoughts (PWRTs and NWRTs; i.e., thoughts about positive/negative work experiences or characteristics) to each other and other off-job WRT constructs, which we integrated into a typology. We coded 520 effect sizes from 171 independent samples (N = 58,682) and conducted a random-effects, individual-correction meta-analysis. We found that PWRTs and NWRTs were unrelated, and psychological detachment was negatively related to NWRTs but unrelated to PWRTs. Furthermore, PWRTs and NWRTs exhibited significantly different relationships with various antecedents (e.g., age, negative affectivity) and outcomes (e.g., work engagement, burnout). Compared to PWRTs and NWRTs, psychological detachment and problem-solving pondering exhibited generally weaker relationships with outcomes. NWRTs contaminated with negative affective strains (i.e., negative work-related thoughts and feelings) exhibited generally stronger relationships with outcomes. Overall, our meta-analytic findings indicate that PWRTs and NWRTs are different and underscore the importance of empirically and conceptually separating PWRTs and NWRTs from each other and other off-job WRT constructs. The findings also complement the nascent literature on interventions that target promoting PWRTs and reducing NWRTs.

     

Implicit sequence learning in a search task

This study investigated the effects of selection demands on implicit sequence learning. Participants in a search condition looked for a target among seven distractors and responded on the target identity. The responses followed a deterministic sequence, and sequence learning was compared to that found in two control conditions in which the targets were presented alone, either at a central location or over a series of unpredictable locations. Sequence learning was obtained in all conditions, and it was equivalent for the two variable location conditions, regardless of the perceptual demands. Larger effects of learning were observed in the central location, both on the indirect measures and on the measures taken from a cued-generation task. The expression of learning decreased selectively in this condition when the sequence validity was reduced over a test block. These results are consistent with the claims that implicit and explicit learning are mixed in this central condition and that implicit learning is not affected by selection difficulty.     

Le comportement de « prise de parole » (voice) : validation de la version française de la mesure de Maynes et Podsakoff

Voice is an essential behaviour that can inhibit or generate processes of innovation and organisational change. To date, few measurement scales adapted to the French context and allowing to analyse this behaviour exists. This article proposes to translate the 4’factors Voice scale from Maynes and Podsakoff (2014). The translation of this scale was tested by 4 studies on different samples of 1275 French workers from various organisational backgrounds. The first studies test the reliability, internal consistency, divergent and convergent validity of the scale. Then, a gender invariance analysis tests the metric properties of the scale. The results obtained present acceptable psychometric qualities that validate the French version.     

How not to be seen: the contribution of similarity and selective ignoring to sustained inattentional blindness

When people attend to objects or events in a visual display, they often fail to notice an additional, unexpected, but fully visible object or event in the same display. This phenomenon is now known as inattentional blindness . We present a new approach to the study of sustained inattentional blindness for dynamic events in order to explore the roles of similarity, distinctiveness, and attentional set in the detection of unexpected objects. In Experiment 1, we found that the similarity of an unexpected object to other objects in the display influences attentional capture: The more similar an unexpected object is to the attended items, and the greater its difference from the ignored items, the more likely it is that people will notice it. Experiment 2 explored whether this effect of similarity is driven by selective ignoring of irrelevant items or by selective focusing on attended items. The results of Experiment 3 suggest that the distinctiveness of the unexpected object alone cannot entirely account for the similarity effects found in the first two experiments; when attending to black items or white items in a dynamic display, nearly 30% of observers failed to notice a bright red cross move across the display, even though it had a unique color, luminance, shape, and motion trajectory and was visible for 5 s. Together, the results suggest that inattentional blindness for ongoing dynamic events depends both on the similarity of the unexpected object to the other objects in the display and on the observer's attentional set.

Wearable activity schedules to promote independence in young children

Activity schedules consist of a series of visual discriminative stimuli, arranged in booklets or binders, which function as prompts for appropriate behavior. Although activity schedules are useful, their typical presentation in binders can be cumbersome and stigmatizing, placing additional barriers for independence and inclusion. The purpose of the present studies was to evaluate the usefulness of a wearable activity schedule and determine whether prompts provided by it would be sufficient to support completion of a complex chain of behaviors by young children. In Experiment 1, the Octopus watch® provided prompts to children of typical development to complete a morning routine independently. In Experiment 2, the usefulness of the watch was evaluated in children with autism spectrum disorder engaged in play activities in a clinical setting. In both experiments, children reliably displayed a greater proportion of independent engagement in target behaviors when prompts were delivered by the watch compared to control conditions.
