The present study examined the impact of working memory capacity (WMC) on college students' ability to solve probability problems while using a self‐explanation strategy. Participants learned to solve probability problems in one of three conditions: a backward‐faded self‐explanation condition, an example problem pairs self‐explanation condition, or a control (no self‐explanation) condition. Even when accounting for the impact of WMC, learning to problem‐solve using self‐explanation led to superior problem‐solving performance. Conditions that prompted self‐explanation during problem‐solving resulted in significantly better problem‐solving performance than the control condition. These findings provide insight into the influence of individual differences on problem‐solving when strategies are provided, as well as information about the effectiveness of the self‐explanation strategy during mathematical problem‐solving.

The Engaged Living Scale (ELS) is a measure of the process of engaged living, defined by Acceptance and Commitment Therapy as the evaluation and performance of valued life activities. This 16-item measure was recently created and has been validated in middle-aged and chronic pain samples. The aim of the present study was to validate the ELS-16 in a young-adult sample and additionally to develop a shorter ELS. This study was conducted using different samples of Portuguese young-adult college students. The dimensionality of the ELS-16 (which was translated to Portuguese from the original Dutch) was tested through a CFA. The adequacy of the shorter ELS (ELS-9) was also tested through a CFA. The scales’ internal reliability and other psychometric qualities were additionally analysed. Results from the CFA suggested that the model benefits from the establishment of correlations between pairs of error terms of items with similar contents. These results led to the decision to shorten the measure by excluding the item of each pair with the lowest communalities. The ELS-9 was then created and its CFA results revealed good to excellent adjustment values and goodness-of-fit indices. Results also showed that the ELS-16 and the ELS-9 present adequate to good psychometric properties. The present study thus shows that these instruments seem to be reliable measures of engaged living and to perform adequately in young-adult college students, with the ELS-9 being a new contribution to health research and allowing faster administrations. 相似文献

Estimates of intelligence in young children with neurodevelopmental disorders are critical for making diagnoses, in characterizing symptoms of disorders, and in predicting future outcomes. The limitations of standardized testing for children with developmental delay or cognitive impairment are well known: Tests do not exist that provide developmentally appropriate material along with norms that extend to the lower reaches of ability. Two commonly used and interchanged instruments are the Mullen Scales of Early Learning (MSEL), a test of developmental level, and the Differential Ability Scales, second edition (DAS-II), a more traditional cognitive test. We evaluated the correspondence of contemporaneous MSEL and the DAS-II scores in a mixed sample of children aged 2–10 years with autism spectrum disorder (ASD), non-ASD developmental delays, and typically developing children across the full spectrum of cognitive ability. Consistent with published data on the original DAS and the MSEL, scores on the DAS-II and MSEL were highly correlated. However, curve estimation revealed large mean differences that varied as a function of the child’s cognitive ability level. We conclude that interchanging MSEL and DAS-II scores without regard to the discrepancy in scores may produce misleading results in both cross-sectional and longitudinal studies of children with and without ASD, and, thus, this practice should be implemented with caution. 相似文献

In order to better understand the heterogeneous nature of Obsessive-Compulsive (OC) symptoms, a typological or a dimensional approach can be used to structure the variety of symptoms into a set of core components. However, there is still no consensus on which approach is the most robust to predict several OC-related criterion measures, especially in adolescents. From this perspective, the current study empirically identified OC classes (i.e., types), and explored whether types or dimensions are the strongest predictors of adolescent OC-related criterion variables. To identify OC classes, we conducted latent class analysis on the Youth Obsessive-Compulsive Symptoms Scale (YOCSS; De Caluwé and De Clercq 2014) that was completed by 682 community and referred adolescents (71.4 % girls, 12–18 years old, mean age = 15.67, SD = 1.53), and we also computed OC dimension scores as outlined in De Caluwé and De Clercq (2014). We subsequently used hierarchical regression analysis to examine the incremental validity of the OC classes beyond the OC domains, and vice versa, in predicting several OC-related criterion variables that were completed by the adolescents or their mothers (N = 325). The results indicated that the two identified OC classes only differed quantitatively but not qualitatively, hence reflecting severity classes, and also showed that OC domains have significant effects beyond the effects of the OC classes, whereas the reverse did not hold. The dimensional approach appears to have the strongest predictive value for OC symptomatology in adolescents, leading to clinical implications for conceptualization and assessment of obsessive and compulsive problems in younger age groups. 相似文献

Purpose
This study draws from social comparison theory to explore why and under which circumstances individuals receiving idiosyncratic deals (i-deals) are likely to help their co-workers.Design
Data were collected with an alumni association of engineers. Participants completed two questionnaires (N = 182 at Time 2).Findings
We find that the relationship between i-deals and helping behavior is not direct, but is mediated by organizational-based self-esteem. This relationship is stronger when i-deal recipients believe that their co-workers do not have the opportunity to get i-deals for themselves.Implications
I-deal recipients are expected to help their colleagues because helping colleagues is consistent with the positive self developed thanks to i-deals. When co-workers have the opportunity to get i-deals for themselves, social comparison between the i-deal recipient and colleagues is likely to be more salient, which strengthen the indirect relationship between i-deal and helping behavior.Originality
This study tests i-deals from the vantage point of social comparison theory rather than from the perspective of social exchange. We thereby provide a richer account of the complexities involved in helping behavior. By exploring contextual variables that are likely to trigger social comparisons, we also expect to better understand the circumstances under which i-deals are likely to be associated with helping behavior.886.

Conventional views purport that mindfulness includes two components: present moment contact (PMC) and nonjudgment. While mindfulness-based interventions that target a broad spectrum of psychopathology, including posttraumatic stress disorder (PTSD), emphasize “being present” as a key mechanism toward wellness, researchers have struggled to measure PMC and assess its clinical utility. Is there any inherent value in PMC or is its clinical utility contingent upon simultaneously engaging in nonjudgment? This pilot study introduces an experimental paradigm designed to dismantle mindfulness and examine the utility of these two components. Forty women with interpersonal victimization histories were assigned to either a nonjudgment condition or a control condition. Next, participants recalled their trauma and then wrote down whatever information was present in their awareness. PMC was measured in both conditions by assessing the frequency of present tense verbs used within these written protocols. As predicted, in the absence of nonjudgment, PMC was related to high negative affect and low positive affect, though unrelated to trauma intrusion frequency. In the nonjudgment condition, PMC was no longer related to state affect and inversely related to trauma intrusion frequency. These pilot data suggest that isolating PMC from nonjudgment may be unhelpful and perhaps iatrogenic. 相似文献

This study aimed to determine whether the recall of gestures in working memory could be enhanced by verbal or gestural strategies. We also attempted to examine whether these strategies could help resist verbal or gestural interference. Fifty-four participants were divided into three groups according to the content of the training session. This included a control group, a verbal strategy group (where gestures were associated with labels) and a gestural strategy group (where participants repeated gestures and were told to imagine reproducing the movements). During the experiment, the participants had to reproduce a series of gestures under three conditions: “no interference”, gestural interference (gestural suppression) and verbal interference (articulatory suppression). The results showed that task performance was enhanced in the verbal strategy group, but there was no significant difference between the gestural strategy and control groups. Moreover, compared to the “no interference” condition, performance decreased in the presence of gestural interference, except within the verbal strategy group. Finally, verbal interference hindered performance in all groups. The discussion focuses on the use of labels to recall gestures and differentiates the induced strategies from self-initiated strategies. 相似文献

Destination memory is the ability to remember the destination to which a piece of information has been addressed (e.g., “Did I tell you about the promotion?”). This ability is found to be impaired in normal ageing. Our work aimed to link this deterioration to the decline in theory of mind. Forty younger adults (M age = 23.13 years, SD = 4.00) and 36 older adults (M age = 69.53 years, SD = 8.93) performed a destination memory task. They also performed the False-belief test addressing cognitive theory of mind and the Reading the mind in the eyes test addressing affective theory of mind. Results showed significant deterioration in destination memory, cognitive theory of mind and affective theory of mind in the older adults. The older adults’ performance on destination memory was significantly correlated with and predicted by their performance on cognitive theory of mind. Difficulties in the ability to interpret and predict others’ mental states are related to destination memory decline in older adults. 相似文献

Many have argued that moral judgment is driven by one of two types of processes. Rationalists argue that reasoned processes are the source of moral judgments, whereas sentimentalists argue that emotional processes are. We provide evidence that both positions are mistaken; there are multiple mental processes involved in moral judgment, and it is possible to manipulate which process is engaged when considering moral dilemmas by presenting them in a non-native language. The Foreign-Language Effect (FLE) is the activation of systematic reasoning processes by thinking in a foreign language. We demonstrate that the FLE extends to moral judgment. This indicates that different types of processes can lead to the formation of differing moral judgments. One implication of the FLE is that it raises the possibility that moral judgments can be made more systematic, and that the type of processing used to form them might be relevant to normative and applied ethics. 相似文献

Although previous research indicates that both employment and adult attachment style have an influence on academic achievement, the interaction of these two factors has not been clarified. The purpose of this study was to investigate the moderating effect of adult attachment style on the relationship between employment status and first semester academic achievement in higher education. A sample of 378 freshman college students answered a series of questionnaires (Academic Amotivation Inventory, the Relationship Questionnaire and demographic), and their high school averages and first semester academic results were obtained from the Registrar’s office. The Analysis of covariance showed that employment status (having employment vs. no employment) and adult attachment style of students (secure vs. dismissing) strongly interacted in predicting academic achievement (first semester average adjusted for high school average, perceived financial burden, and amotivation). More specifically, the first semester averages of secure students with or without employment, and that of dismissing students without employment was indistinguishable. However, dismissing students with employment had significantly lower first semester averages than the secure students. This study showed that dismissing students entering postsecondary education who also have employment are at greater risk of academic difficulties than students with a secure attachment style. 相似文献
