When families migrate the new culture and culture of origin may conflict, with possible consequences for parenting and children's development. Turks form one of the largest immigrant groups in Western Europe, and there is also much movement within Turkey. This study compares three groups; Turkish immigrants to the UK (N = 142), migrants within Turkey (N = 229), and Turkish non-migrants (locals, N = 396). The children were 39–71 months old (M = 58 months, SD = 6.5), 392 were boys and 375 were girls. Parents supplied data on family characteristics and parenting, and teachers supplied data on children's behaviour. Using Baumrind's parenting model and allowing for background effects, compared to non-migrants and migrants, the immigrant parents were less permissive and more authoritarian. Children in immigrant families had more externalizing problems, internalizing problems and emotional dysregulation and less social competence than migrant and non-migrant children. Multilevel models and structural equation models both found that these effects upon child behaviour were evident after taking into account demographic factors and were not eliminated by taking into account parenting style differences, and thus suggest that immigration and migration are risk factors for child behaviour. Effects of immigrant and migrant status were partly direct and partly indirect via their effects on parenting.  相似文献

Preschoolers were tested on a variety of oddity problems—that is, problems where one object in a set of four differed from the other three on one dimension. These dimensions consisted of colour, size, or form. The children were most accurate on size oddity problems in which one object was bigger than the others. They were almost as accurate on colour oddity problems. Form problems were next, and size oddity problems wherein the odd object was smaller than the other three objects were next. These decalages are interpretable in terms of relational complexity theory and executive function.  相似文献

Collective moral disengagement refers to shared group beliefs that morally justify negative actions. This study reports an initial validation of the newly developed Classroom Collective Moral Disengagement Scale (CCMDS) for adolescents. This self-report instrument assesses the degree to which mechanisms of moral disengagement are shared by students in their class. Data were collected from two samples of 486 and 654 adolescents attending middle and high schools in Italy. Through exploratory and confirmatory factor analyses the unidimensional structure of the scale was established. Multigroup analyses demonstrated configural, metric and scalar invariance of the model across age and gender groups. The final version of the scale consists of 17 items and it has good internal consistency and validity. It is concluded that the scale is a promising measure for research concerning group level morality.  相似文献

In this paper, we study the connections between working memory capacity (WMC) and learning in the context of economic guessing games. We apply a generalized version of reinforcement learning, popularly known as the experience-weighted attraction (EWA) learning model, which has a connection to specific cognitive constructs, such as memory decay, the depreciation of past experience, counterfactual thinking, and choice intensity. Through the estimates of the model, we examine behavioral differences among individuals due to different levels of WMC. In accordance with ‘Miller’s magic number’, which is the constraint of working memory capacity, we consider two different sizes (granularities) of strategy space: one is larger (finer) and one is smaller (coarser). We find that constraining the EWA models by using levels (granules) within the limits of working memory allows for a better characterization of the data based on individual differences in WMC. Using this level-reinforcement version of EWA learning, also referred to as the EWA rule learning model, we find that working memory capacity can significantly affect learning behavior. Our likelihood ratio test rejects the null that subjects with high WMC and subjects with low WMC follow the same EWA learning model. In addition, the parameter corresponding to ‘counterfactual thinking ability’ is found to be reduced when working memory capacity is low.  相似文献

When facing potential conflicts, whether to make interventions is an important decision for air traffic controllers and vital for aviation safety and efficiency. While many task-related factors in influencing such decisions have been identified, the large portion of individual differences has remained insufficiently explained. This paper proposes that controllers with a more holistic thinking style will be more likely to make interventions because they envision more uncertainties in the system which can lead to a higher level of perceived risk and a greater likelihood to take proactive measures. To test these hypotheses, forty-two licensed controllers were invited to complete a questionnaire measuring holistic thinking style and later a conflict detection/resolution task. Multilevel regression analyses showed that (1) when the real risk level (the minimum lateral distance between two converging aircraft) dropped, controllers who think more holistically still tended to maintain a higher risk perception level (perceived likelihood of aircraft collision in the future) which lead to a higher intervention ratio and (2) even when real and perceived risk levels were controlled, those who think more holistically were more likely to make interventions. These findings are discussed with reference to literature in cognitive style, risk perception and workload management. Potential implications for personnel selection and training are also discussed.  相似文献

This study aimed to evaluate the latent structure of the Prospective and Retrospective Memory Questionnaire (PRMQ) and to estimate the reliability and validity of scores from the measure in a Nigerian adult population (N = 758; age range = 18 - 63 years; females = 52.24%). Respondents also completed the Cognitive Failures Questionnaire (CFQ). The data were analysed utilising confirmatory factor analysis (CFA). The results suggest the PRMQ to have a tripartite structure characterised by the following features: general memory, plus eight prospective and eight retrospective memory items. Scores from the PRMQ had evidence of convergent validity with the CFQ. The reliability of scores from the PRMQ was of acceptable magnitude for the research purposes investigated in the study.  相似文献

Background: This study aimed to determine whether there were gender differences in trauma types and cognitive-emotional themes among veterans with deployment-related posttraumatic stress disorder (PTSD). Methods: Case notes or writing excerpts from two pilot studies were reviewed to determine types of traumas and emerging themes, with 20 women and 31 men comprising the sample. Results: Most women developed PTSD after sexual assault, with reactions emphasizing mistrust, betrayal, and anger. Men experienced more combat, with reactions including survivor guilt, moral injury, and horror. Conclusions: Both genders developed PTSD, but the causes of and reactions to their traumas differed. Emerging themes can be useful treatment foci.  相似文献

The present research evaluates how people integrate factual ‘if then’ and semifactual ‘even if’ conditional premises in an inference task. The theory of mental models establishes that semifactual statements are represented by two mental models with different epistemic status: ‘A & B’ is conjectured and ‘not-A & B’ is presupposed. However, following the principle of cognitive economy in tasks with a high working memory load such as reasoning with multiple conditionals, people could simplify the deduction process in two ways, by discarding: (a) the presupposed case and/or (b) the epistemic status information. In Experiment 1 and Experiment 2, we evaluated each of these hypotheses. In Experiment 1, participants make inferences from two conditionals: two factual conditionals or one factual and one semifactual, with different representations. In Experiment 2, participants make inferences with a factual conditional followed by two different semifactual conditionals that share the same representations but differ in their epistemic status. Accuracy and latency data suggest that people think of both the conjectured and the presupposed situations, but do not codify the epistemic status of either when the task does not require it. The results are discussed through theoretical predictions about how people make inferences from different connected conditionals.  相似文献
