The identity‐to‐politics link assumes that individuals who share a certain demographic feature also share common political pursuits. This article critically examines that presumed relationship by analyzing how voting probability is affected by social identification in combination with other elements—namely, perception of shared grievances and group resources. Tallying responses from Muslim immigrants in Belgium, Germany, Switzerland, and the United Kingdom via surveys conducted for the European research project EURISLAM, this study supports the assumption that social identification affects voting in specific circumstances. The results show that identifying with the origin country decreases voting probability among Muslim immigrants in Europe. Another finding was the context‐specific effect of social identification. That is, origin‐country identification's effect is contingent on an individual's perception of shared grievances and national identification; and origin country and religious identifications' effects are contingent on an individual's perception of shared grievances, national identification, and group differences.  相似文献

As the preschool years are a formative period for long-term physical and mental health, this period is recognised as an important window for early effective intervention. Parenting behaviour is a key factor to target in order to optimise child development. Group-based interventions for parents are considered efficient and cost effective methods of early intervention and have been found to improve child behaviour and adjustment. Self-efficacy is key to behaviour change and as such parental self-efficacy should be a consideration in interventions aimed at influencing parenting behaviour. Therefore, the purpose of this systematic review was to examine the impact of group-based early interventions for parents of preschool children on parental self-efficacy. Nine databases were searched (ASSIA, CINAHL, EMBASE, Maternity and Infant Care, Ovid Medline, PsycINFO, Pubmed, Science Direct and Web of Science). Studies were included if they were a randomised controlled trial of a group-based intervention for parents of preschool children and measured change in parental self-efficacy. Fifteen studies were identified. Although changes in parental self-efficacy following a group-based intervention were noted in the majority of studies reviewed, the methodological quality of the studies included in the review means these findings have to be interpreted with caution; only seven studies were rated to be methodologically adequate. Further research is needed to understand the mechanisms by which these interventions may improve parental self-efficacy. Studies specifically examining the impact of such interventions on paternal self-efficacy are also warranted.  相似文献

Embodied cognition accounts posit that concepts are grounded in our sensory and motor systems. An important challenge for these accounts is explaining how abstract concepts, which do not directly call upon sensory or motor information, can be informed by experience. We propose that metaphor is one important vehicle guiding the development and use of abstract concepts. Metaphors allow us to draw on concrete, familiar domains to acquire and reason about abstract concepts. Additionally, repeated metaphoric use drawing on particular aspects of concrete experience can result in the development of new abstract representations. These abstractions, which are derived from embodied experience but lack much of the sensorimotor information associated with it, can then be flexibly applied to understand new situations.  相似文献

This study aimed to construct a model to explain trauma exposure and life satisfaction among black South African school learners. A random sample of 366 black adolescents selected from ten South African schools participated (females = 63.2%; rural = 24.2%; mean age = 13.9 years). The school learners were surveyed on trauma exposure, resources, coping and resilience, and life satisfaction. A structural equation modelling analysis indicated that interpersonal, intrapersonal and affective strengths, coping skills, family involvement, and school functioning were associated with increased resilience, which in turn predicted life satisfaction. Interventions aimed at increasing resilience in contexts characterised by high levels of trauma exposure should prioritise helping adolescents access both internal and external resources, such as coping skills and family involvement respectively.  相似文献

In recent years many controversial verdicts and studies have brought discussions about the quality of expert opinions in family law into the focus of the media, political and expert public spheres. With the coalition contract, the ruling parties agreed on improving the quality of expert opinions, especially in the sector of family law, in collaboration with professional institutions. Representatives of the legal, psychological and medical associations, the Federal Bar Association and the Federal Chamber of Psychotherapists worked out guidelines for expert opinions in family law in cooperation with the Federal Ministry of Justice and Consumer Protection. The three main quality assurance aspects are scientifically founded procedures, transparency and traceability. These requirements are concretely illustrated in this article with recommendations concerning the procedure and composition of expert opinions.  相似文献

This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions – Improvement (CGI-I) scale. Cronbach’s alpha and intraclass correlations (ICC) assessed internal consistency and test-retest reliability, with correlations evaluating validity. Receiver- and Quality-Receiver Operating Characteristic analyses assessed the efficiency of percent and raw-reduction cutoffs associated with positive treatment response. The PTQ demonstrated good internal consistency (α = 0.80 to 0.86), excellent test-retest reliability (ICC = .84 to .89), good convergent validity with the YGTSS and HM/VTS, and good discriminant validity from hyperactive, obsessive-compulsive, and externalizing (i.e., aggression and rule-breaking) symptoms. A 55% reduction and 10-point decrease in PTQ Total score were optimal for defining positive treatment response. Findings help standardize tic assessment and provide clinicians with greater clarity in determining clinically meaningful tic symptom change during treatment.  相似文献

Night eating syndrome (NES) is characterized by excessive evening and/or nocturnal eating episodes. Studies indicate an attentional bias towards food in other eating disorders. For NES, however, evidence of attentional food processing is lacking. Attention towards food and non-food stimuli was compared using eye-tracking in 19 participants with NES and 19 matched controls without eating disorders during a free exploration paradigm and a visual search task. In the free exploration paradigm, groups did not differ in initial fixation position or gaze duration. However, a significant orienting bias to food compared to non-food was found within the NES group, but not in controls. A significant attentional maintenance bias to non-food compared to food was found in both groups. Detection times did not differ between groups in the search task. Only in NES, attention to and faster detection of non-food stimuli were related to higher BMI and more evening eating episodes. The results might indicate an attentional approach-avoidance pattern towards food in NES. However, further studies should clarify the implications of attentional mechanisms for the etiology and maintenance of NES.  相似文献

Accumulating evidence suggests that in order to understand and respond to the difficulties presented by illness, patients construct their own "common sense" cognitive model of illness. This study set out to examine self-help group members, and students' beliefs about their atopic dermatitis (AD) and to investigate their relationship with symptom report and clinical and demographic variables. A total of 284 participants with AD undertook a self-assessment of their disease severity and completed the Revised Illness Perception Questionnaire. The most frequent symptoms associated with AD were itching, sleep difficulties and pain. The most commonly reported triggers of AD were stress, hereditary factors and emotional state. Over 75% of participants believed that their condition would be chronic. Self-help group members reported more significant consequences of the condition, a greater emotional impact, while the student group felt they had more personal control of their AD. Multiple regression analyses indicated that illness beliefs, in particular perceived consequences associated with AD and personal control, accounted for a significant proportion of the variance in emotional response to the condition. This study suggests that participants' beliefs and emotional response are more strongly associated with the meaning they ascribe to their condition rather than its severity.  相似文献

Objective

Recent research suggests that binge eating is a common experience in youth. However, it remains largely unknown how children's binge eating presents in everyday life and which psychological factors serve to maintain this binge eating.

Methods

Children aged 8-13 years with binge eating (n = 59), defined as at least one episode of loss of control (LOC) over eating within the past three months, and 59 matched children without LOC history were recruited from the community. Following a combined random- and event-sampling protocol, children were interviewed about their day-to-day eating behavior, mood, and eating disorder-specific cognitions using child-specific cell phones during a 4-day assessment period in their natural environment.

Results

LOC episodes led to a significantly greater intake of energy, particularly from carbohydrates, than regular meals of children with and without LOC eating. While LOC episodes were preceded and followed by cognitions about food/eating and body image, there was minimal evidence that negative mood states were antecedents of LOC eating.

Conclusions

The results provide support for the construct validity of LOC eating in children. Maintenance theories of binge eating for adults apply to children regarding eating disorder-specific cognitions, but the association with affect regulation difficulties requires further investigation.  相似文献

The NMDA receptor (NMDAR) subunit GluN1 is an obligatory component of NMDARs without a known functional homolog and is expressed in almost every neuronal cell type. The NMDAR system is a coincidence detector with critical roles in spatial learning and synaptic plasticity. Its coincidence detection property is crucial for the induction of hippocampal long-term potentiation (LTP). We have generated a mutant mouse model expressing a hypomorph of the Grin1N598R allele, which leads to a minority (about 10%) of coincidence detection-impaired NMDARs. Surprisingly, these animals revealed specific functional changes in the dentate gyrus (DG) of the hippocampal formation. Early LTP was expressed normally in area CA1 in vivo, but was completely suppressed at perforant path-granule cell synapses in the DG. In addition, there was a pronounced reduction in the amplitude of the evoked population spike in the DG. These specific changes were accompanied by behavioral impairments in spatial recognition, spatial learning, reversal learning, and retention. Our data show that minor changes in GluN1-dependent NMDAR physiology can cause dramatic consequences in synaptic signaling in a subregion-specific fashion despite the nonredundant nature of the GluN1 gene and its global expression.According to Hebb''s postulate, neurons require a molecular mechanism to detect synchronous activity in order to change the strength of synaptic connectivity (Hebb 1949). NMDA receptors (NMDARs) are molecular coincidence detectors, and selective NMDAR antagonists block the induction of long-term potentiation (LTP) in both the dentate gyrus (DG) and CA1 regions of the hippocampus (Bliss and Collingridge 1993; Martin et al. 2000). NMDARs have been long known for their role in spatial learning, but more recently have been implicated in other forms of cognitive function and dysfunction (Gruart et al. 2006; Whitlock et al. 2006; Castner and Williams 2007; Kristiansen et al. 2007; Wilson and Linster 2008).Neuronal NMDARs are hetero-tetrameric ligand-gated ion channels typically comprised of two types of subunits. Two copies of the mandatory GluN1 subunit (or NR1 subunit [Collingridge et al. 2009] encoded by Grin1) are associated with two copies from the GluN2 family, GluN2A–D (or NR2A–D). The GluN1 subunit is expressed ubiquitously both spatially and temporally throughout the developing and adult brain. Global knockout mice models of the GluN1 subunit are postnatally lethal within hours after birth (Forrest et al. 1994; Li et al. 1994), and cell-specific GluN1 mice knockouts (Tsien et al. 1996; Nakazawa et al. 2002; McHugh et al. 2007; Niewoehner et al. 2007) have provided insights on how specific synapses and regional neuronal networks are dependent on NMDAR function.The early postnatal lethality of the global GluN1 knockout is in contrast to the null mutants of the four AMPA receptor genes and other major synaptic proteins, such as αCaMKII (Silva et al. 1992a,b; Jia et al. 1996; Zamanillo et al. 1999; Meng et al. 2003). This can be at least partially explained by the absence of any close GluN1 homologs, which could functionally compensate for the absence of the GluN1 subunit. Recombinant expression studies defined the GluN1 subunit as a mandatory component of NMDARs. This constellation provides a specific opportunity to test whether different local neuronal subnetworks are affected differentially by mutant Grin1 alleles associated with subtle alterations of the functional properties of NMDARs.GluN1 subunits with the N598R point mutation (GluN1R) yield functional NMDARs that are Mg2+ insensitive and Ca2+ impermeable (Burnashev et al. 1992; Mori et al. 1992). The Grin1N598R allele that codes for GluN1R subunits is a gain-of-function mutation that is dominant lethal, even in heterozygous and hemizygous lines (Single et al. 2000; Rudhard et al. 2003). NMDARs with GluN1R subunits do not act as coincidence detectors and, interestingly, mice expressing exclusively the GluN1R allele lack whisker-related pattern formation in the neonate brainstem (Rudhard et al. 2003).To investigate the functional importance of GluN1 subunits with the N598R point mutation, we took advantage of the generation of a variant mutant line of mice (GluN1Rneo/+) expressing a minority (around 10%) of these mutant NMDARs. Even though the majority of the NMDARs are normal, all neurons expressing NMDARs will contain a subset of receptors carrying this mutation.Therefore, this mouse model is an ideal candidate to study the impact of subtle alterations of NMDAR function on different neuronal networks, such as those comprising the hippocampal formation.Studies examining region-specific targeted disruption of GluN1 expression in subregions of the hippocampus have revealed subtle yet important contributions of this NMDAR subunit in synaptic plasticity and spatial learning and memory. CA1-restricted knockout of GluN1 expression in the hippocampus caused impaired spatial learning and memory as well as reduced CA1-LTP (Tsien et al. 1996). In the case of the disruption of GluN1 expression in the DG region of the hippocampus, more subtle behavioral impairments were apparent, including the inability to discriminate between two similar contexts (pattern separation) and deficits in spatial working memory despite normal LTP in the CA1 region (McHugh et al. 2007; Niewoehner et al. 2007).Our GluN1Rneo/+ mice differ from the region-specific GluN1 mutant mice in that they express the mutant hypomorph at the same level in different subregions of the hippocampus. Interestingly, we found that this allele leads to substantial differences in short- and long-term plasticity between area CA1 and the DG of the hippocampus. The specific impairment in the DG was accompanied by impaired spatial recognition, spatial learning, reversal learning, and retention. Our data establish the possibility of a circuit-specific phenotype caused by a mutant variant of a globally expressed major nonredundant synaptic protein.  相似文献
