Do girls attending a single-sex school outperform their same-sex counterparts attending co-educative schools when solving a mental rotation task known to produce substantial gender differences favoring males? In total, 252 German pupils (126 8th/12th graders each) attending single-sex (84 girls) or co-educative (84 boys and girls each) high-schools in North-Rhine Westphalia (west Germany) participated. All pupils completed the ??Mental Rotations Test?? (MRT). We found that in grade 12 girls attending a single-sex school outperformed their same-sex counterparts attending co-educational schools. In grade eight no differences between both groups were observed. As expected, the well known gender difference between 12th grade boys and co-educative girls had been found. Expectations as well as possible consequences are discussed.  相似文献

In many societies the prevalence of behavioural problems in school-aged children varies by national origin. We examined the association between national origin and behavioural problems in 1½-year-old children. Data on maternal national origin and the Child Behavior Checklist for toddlers (n?=?4943) from a population-based cohort in the Netherlands were used. Children from various non-Dutch backgrounds all had a significantly higher mean behavioural problem score. After adjustment for family risk factors, like family income and maternal psychopathology, the differences attenuated, but remained statistically significant. Non-Dutch mothers with immigration risk factors, such as older age at immigration or no good Dutch language skills, reported significantly more behavioural problems in their offspring. In conclusion, the present study indicated more behavioural problems in immigrant toddlers from various backgrounds. Researchers and policymakers aiming to tackle disparities in behavioural problems should take into account that risks associated with national origin are intertwined with unfavourable family and immigration characteristics.  相似文献

Work-family scholars now recognize the potential positive effects of participation in one life domain (i.e., work or family) on performance in other life domains. We examined how employees might benefit from team resources, which are highly relevant to the modern workplace, in both work and nonwork domains via work-family enrichment. Using the Resource-Gain-Development model (Wayne, Grzywacz, Carlson, & Kacmar, 2007), we explored how team resources contribute to enrichment and resulting project and family satisfaction. Using multilevel structural equation modeling (ML-SEM) to analyze student data (N = 344) across multiple class projects, we demonstrated that individuals with team resources were more likely to experience both work-to-family and family-to-work enrichment. Further, enrichment mediated the relationship between team resources and satisfaction with the originating domain.  相似文献

Professional skills to adequately manage patient aggression are a prerequisite for nurses working in psychiatric hospitals. These ‘technical’ skills, however, are necessary but not sufficient for effective nurse intervention. The attitude of nurses' towards client aggression also contributes to their response to a patient's behaviour. In order to study the domains (types) of attitudes towards aggression, a sample was taken of nurses working in the fields of general psychiatry (n=288), psychiatry for children and adolescents (n=242) and psychogeriatrics (n=88). A cross‐sectional survey design was adopted for the study. The Attitudes Towards Aggression Scale (ATAS) consisting of 32 items is presented, representing three types of attitudes towards aggression: aggression as a ‘harming’ reaction, a ‘normal’ reaction and a ‘functional’ reaction. The strongest predictors of the type of attitude respondents had towards the aggressive behaviour of their clients were (1) field, (2) setting they worked in, (3) gender and (4) type of shifts they predominantly had. Although the measure of domains of nurses' attitudes towards aggression needs further psychometric testing, it can be a useful tool in clinical practice for the assessment of staff attitudes towards aggression. This can support the decision‐making about the management of aggressive behaviour on a ward. Aggr. Behav. 00:1–10, 2005. © 2005 Wiley‐Liss, Inc.  相似文献

Despite centuries of contact and conquest, Indigenous communities persist in maintaining their cultures and psychologies. Key to this success in cultural survival is the maintenance of Indigenous languages, which contain distinct worldviews. However, Indigenous languages are at risk, with fewer and fewer fluent Elder speakers. Fortunately, there remain committed groups of community educators who carry out Indigenous language education. Current mainstream teacher education programs do not typically introduce the importance of Indigenous language education to teacher candidates, who are the next generation of K‐12 teachers. We view this as highly problematic, and thus carried out a proof‐of‐concept project in which one U.S. university's American Indian/Alaska Native teacher candidates collaborated with, and learned from, Indigenous language educators during a two‐week‐long summer institute at the university. In our article, we share three main findings, based on qualitative analyses of daily‐written student journals collected during the two‐week pilot project: (a) Indigenous language education supports the social justice vision in the American Psychological Association's Multicultural Guidelines; (b) intergenerational educational opportunities are invaluable for affirming Indigenous psychologies; and (c) Indigenous community language educators do important survivance work. Our findings provide insight into how Indigenous language education is crucial for advancing education that honors Indigenous community psychological well‐being.  相似文献

Many researchers across many experimental domains utilize the latency of spoken responses as a dependent measure. These measurements are typically made using a voice key, an electronic device that monitors the amplitude of a voice signal, and detects when a predetermined threshold is crossed. Unfortunately, voice keys have been repeatedly shown to be alarmingly errorful and biased in accurately detecting speech onset latencies. We present SayWhen--an easy-to-use software system for offline speech onset latency measurement that (1) automatically detects speech onset latencies with high accuracy, well beyond voice key performance, (2) automatically detects and flags a subset of trials most likely to have mismeasured onsets, for optional manual checking, and (3) implements a graphical user interface that greatly speeds and facilitates the checking and correction of this flagged subset of trials. This automatic-plus-selective-checking method approaches the gold standard performance of full manual coding in a small fraction of the time.  相似文献

This study investigated the effects of both environmental enrichment and individual behavioural characteristics on spatial cognitive capabilities of pigs, using a novel latent spatial learning paradigm based on Tolman’s detour experiments (1948). Pigs were housed either in ‘barren’ pens or in pens enriched with straw bedding from birth. Pigs were restrained in a Backtest at 10 and 17 days postpartum. Based on their escape behaviour in this test, which has been shown to reflect their behavioural style, six ‘high-resisting’(HR) and six ‘low-resisting’ (LR) pigs were selected from each housing environment (n = 24 in total). At 12 weeks of age, pairs of pen mates (LR and HR) were exposed to a maze three times (exploration trials). Pigs were then placed individually in the maze, and social reinstatement proved to be a strong incentive to find the exit leading to the home pen. We subsequently blocked the direct route to the exit, forcing animals to find a detour (memory test 1, MT1). This test was repeated once to investigate the relative improvement, i.e. detour learning (memory test 2, MT2). Housing condition and Backtest response strongly affected exploration patterns. In spite of this, no effects on performance during the subsequent memory tests were found. Performance was substantially improved in MT2, indicating that once a goal is apparent, pigs are able to solve a complex spatial memory task easily. In conclusion, social reinstatement provided a good incentive to complete a spatial task, and the substantial improvement in performance between MT1 and MT2 stresses the need for task complexity when testing spatial memory in pigs. Housing conditions or individual behavioural style did not affect spatial memory during MT1 or MT2. However, housing environment and behavioural style strongly affected explorative behaviour of pigs in an unfamiliar maze during both exploration trials and memory tests. This implicates that apparent effects of environmental enrichment on spatial learning and memory in pigs might reflect differences in explorative patterns rather than in cognitive processes.  相似文献
