The aim of this short-term longitudinal study, based on the system theory, was to test the association between different aspects of family functioning of preschoolers and their socioaffective competencies at the end of the first grade. The total sample included 278 children (137 boys and 141 girls) and their families. The analysis of variance results regarding the aspects of family cohesion and harmony showed that preschoolers from more cohesive families display more social skills, while those from more conflicting families display more externalizing behavior problems (aggression and irritability). With respect to the family's ability to resolve problems, it was observed that, especially for middle and upper class families, this aspect is associated with better social skills and fewer internalized behavior problems. Overall, results of the present study suggest that the family functioning at early stage might influence children's abilities to regulate their emotions and to establish/maintain important relationships with peers and teachers in their early school years.  相似文献

The posterior parietal cortex (PPC) is fundamental for sensorimotor transformations because it combines multiple sensory inputs and posture signals into different spatial reference frames that drive motor programming. Here, we present a computational model mimicking the sensorimotor transformations occurring in the PPC. A recurrent neural network with one layer of hidden neurons (restricted Boltzmann machine) learned a stochastic generative model of the sensory data without supervision. After the unsupervised learning phase, the activity of the hidden neurons was used to compute a motor program (a population code on a bidimensional map) through a simple linear projection and delta rule learning. The average motor error, calculated as the difference between the expected and the computed output, was less than 3°. Importantly, analyses of the hidden neurons revealed gain-modulated visual receptive fields, thereby showing that space coding for sensorimotor transformations similar to that observed in the PPC can emerge through unsupervised learning. These results suggest that gain modulation is an efficient coding strategy to integrate visual and postural information toward the generation of motor commands.  相似文献

Individuals decide to use healthcare when the expected benefits outweigh the perceived costs. One of these cost factors in this decision can be stigma. So far, it has not been researched how former soldiers of the German Armed Forces with a service-induced mental illness perceive stigma and how it influences their healthcare use. As stigma is shaped by the socio-cultural context, the setting of the potential healthcare use must be considered. Narrative interviews were conducted with 33 former soldiers with mental health problems. The data were analyzed using a thematic analysis approach, in which codes were formed and emerging themes were systemized. The relationship between stigma and healthcare use was analyzed. Occupational discrimination and social exclusion were experienced in both in the military and civilian context, but stigma functioned differently in each context. In the military context, former soldiers’ self-stigma of mentally ill individuals being weak was in stark contrast to their internalized military standards. This contrast let them avoid disclosure and subsequent healthcare use. In civilian context, the participants perceived 2 different stigma costs: mental illness stigma and former soldier stigma (i.e., stigmatization because of their military past). Both were perceived as barriers to healthcare use. A model, illustrating these different stigma costs in the different contexts, was developed. Further research on the link between stigma and healthcare use of this group is urgently needed.  相似文献

Recent research suggests that there is an advantage for processing configural information in scenes and objects. The purpose of this study was to investigate the extent to which attention may account for this configural advantage. In Experiment 1, we found that cueing the location of change in single object displays improved detection performance for both configural and shape changes, yet cueing attention away from the location of change was detrimental only for shape change detection. A configural advantage was present for each cueing condition. Experiments 2A and 2B examined whether the configural advantage persisted in conditions where attention was distributed more widely, using a visual search paradigm. Although searches for configural changes were faster than those for shape changes across all set sizes, both types of information appeared to be processed with similar efficiency. Overall, these results suggest that the configural advantage is independent of the location or distribution of visual attention.  相似文献

This study tests whether cognitive failures mediate effects of work-related time pressure and time control on commuting accidents and near-accidents. Participants were 83 employees (56% female) who each commuted between their regular place of residence and place of work using vehicles. The Workplace Cognitive Failure Scale (WCFS) asked for the frequency of failure in memory function, failure in attention regulation, and failure in action execution. Time pressure and time control at work were assessed by the Instrument for Stress Oriented Task Analysis (ISTA). Commuting accidents in the last 12 months were reported by 10% of participants, and half of the sample reported commuting near-accidents in the last 4 weeks. Cognitive failure significantly mediated the influence of time pressure at work on near-accidents even when age, gender, neuroticism, conscientiousness, commuting duration, commuting distance, and time pressure during commuting were controlled for. Time control was negatively related to cognitive failure and neuroticism, but no association with commuting accidents or near-accidents was found. Time pressure at work is likely to increase cognitive load. Time pressure might, therefore, increase cognitive failures during work and also during commuting. Hence, time pressure at work can decrease commuting safety. The result suggests a reduction of time pressure at work should improve commuting safety.  相似文献

Cognitive flexibility is one of the essential mental abilities underlying creative thinking. Previous findings have shown that cognitive flexibility can be enhanced by schema violations, and it has been suggested that active involvement is needed for schema violations to facilitate cognitive flexibility. The possibility that identification with an actor performing a schema violation (i.e., corepresenting an active schema violation) can enhance cognitive flexibility was investigated in 2 studies. In the first study, under conditions of high or low identification, participants watched an actor preparing a sandwich. The way the actor made the sandwich followed either a schema violation or contained the normal schema of preparing a sandwich. When identification was high, watching a schema-violation-enhanced cognitive flexibility as compared to watching the corresponding normal event. No effect of schema violation occurred under conditions of low identification. As little is known about the neural correlates of schema violations, in the second study the brain activity during schema violations was explored by means of functional Magnetic Resonance Imaging (fMRI). Participants were instructed to identify with an actor and brain activity was measured while participants watched the actor performing a schema violation or the corresponding normal schema. Activity in the temporal parietal junction (TPJ), a brain region that is associated with violation of expectations, was higher in the schema-violation condition than in the normal schema condition. These findings enhance the theoretical understanding of the effects of schema violations and may provide important practical implications in various settings where creative thinking is needed.  相似文献

In this paper we propose an extension of Defeasible Logic to represent and compute different concepts of defeasible permission. In particular, we discuss some types of explicit permissive norms that work as exceptions to opposite obligations or encode permissive rights. Moreover, we show how strong permissions can be represented both with, and without introducing a new consequence relation for inferring conclusions from explicit permissive norms. Finally, we illustrate how a preference operator applicable to contrary-to-duty obligations can be combined with a new operator representing ordered sequences of strong permissions. The logical system is studied from a computational standpoint and is shown to have linear computational complexity.  相似文献

It is customarily assumed that propositional attitudes present two independent components: a propositional component and a psychological component, in the form of an attitudes. These two components are caught by means of two different methods: propositions by some model theoretic theory, psychological attitudes by making appeal to their functional or psychological role. Some authors have seek a convergence by individuating propositions by some Functional role semantics. In this paper I show that when it comes to emotional attitudes with propositional content, either the independence of proposition and attitude collapses or functional role semantics brings to unstable individuation conditions for propositions. Some consequences of these two outcomes are considered.  相似文献
