Two experiments compared 7- and 8-year-olds' and 9- and 10-year-olds' ability to use semantic analysis and inference from context to understand idioms. We used a multiple-choice task and manipulated whether the idioms were transparent or opaque, familiar or novel, and presented with or without a supportive story context. Performance was compared with that of adults (Experiment 1) and 11- and 12-year-olds (Experiment 2). The results broadly support Cacciari and Levorato's global elaboration model of figurative competence with a notable exception: Even the youngest children were able to use semantic analysis to derive the meanings of transparent idioms as well as being sensitive to meaning in context. The findings show that young children process language at both the small-grain phrase level and the discourse level to establish figurative meaning, and they demonstrate that the language processing skills that aid idiom comprehension, as well as idiom knowledge itself, are still not fully developed in 11- and 12-year-olds. 相似文献

We examined the psychological dimensions of parents’ perceptions of their infant children and their own abilities as parents
at two observation points in a racially and socio-economically diverse sample of 174 mothers. Parenting perceptions and life
circumstances were hypothesized to predict interactive behavior observed in the home. Baseline assessments were conducted
in hospital, within 36 hr of delivery. Follow-up assessments were conducted in their homes when the children were 6 to 12
months old. Of five major psychological constructs studied, only parents’ perceptions of children, represented particularly
by empathic responsiveness and absence of role-reversal, predicted the quality of behavioral interactions in the home. Perceptions
of children were themselves predicted by parents’ perceptions of the quality of care they themselves received from their own
parents, and by lifestyle stress. Our findings suggest that clinical interventions with parents should include a focus on
strengthening reflective capacities with respect to caregiving experiences, and empathic responsiveness to their children. 相似文献

Like extinction, latent inhibition of conditioned fear in mice is blocked by systemic inhibition of L-type voltage-gated calcium channels 下载免费PDF全文
Having recently shown that extinction of conditioned fear depends on L-type voltage-gated calcium channels (LVGCCs), we have been seeking other protocols that require this unusual induction mechanism. We tested latent inhibition (LI) of fear, because LI resembles extinction except that cue exposures precede, rather than follow, cue-shock pairing. Systemic injections of two LVGCC inhibitors, nifedipine and diltiazem, before pre-exposure blocked LI completely with no evidence of state-dependent learning. The results indicate that extinction and LI share a common molecular requirement and may support the notion that LI, like extinction, is a form of inhibitory learning. 相似文献

The L-type calcium channel blocker nifedipine impairs extinction, but not reduced contingency effects, in mice 下载免费PDF全文
We recently reported that fear extinction, a form of inhibitory learning, is selectively blocked by systemic administration of L-type voltage-gated calcium channel (LVGCC) antagonists, including nifedipine, in mice. We here replicate this finding and examine three reduced contingency effects after vehicle or nifedipine (40 mg/kg) administration. In the first experiment, contingency reduction was achieved by adding USs to the training protocol (degraded contingency), a phenomenon thought to be independent of behavioral inhibition. In the second experiment, contingency reduction was achieved by varying the percentage of CS-US pairing, a phenomenon thought to be weakly dependent on behavioral inhibition. In the third and fourth experiments, contingency reduction was achieved by adding CSs to the training protocol (partial reinforcement), a phenomenon thought to be completely dependent on behavioral inhibition. We found that none of these reduced contingency effects was impaired by nifedipine. In a final experiment, we found that extinction conducted 1 or 3 h post-acquisition, but not immediately, was LVGCC-dependent. Taken together, the results suggest that reduced contingency effects and extinction depend on different molecular mechanisms and that LVGCC dependence of behavioral inhibition develops with time after associative CS-US learning. 相似文献

The context-free diagnoses outlined by the Diagnostic and Statistical Manual of Mental Disorders might not provide enough information to represent the heterogeneity observed in depressed patients. Interpersonal factors have been linked to depression in a mutually influencing pathoplastic relationship where certain problems, like submissiveness, are related to symptom chronicity. This study evaluated interpersonal pathoplasticity in a range of depressive presentations. We examined archival data collected from 407 participants who met criteria for major depressive disorder (MDD), dysthymic disorder (DD), or subthreshold depression (sD). Latent profile analysis (LPA) identified 5 interpersonal subtypes (vindictive, intrusive, socially avoidant, exploitable, and cold). Apart from gender, the subtypes did not differ significantly on demographic characteristics, psychiatric comorbidity, or self-report depression severity. Socially avoidant participants were more likely to meet criteria for a clinical depression diagnosis (MDD or DD), whereas vindictive participants were more likely to have sD. Our results indicate that interpersonal problems could account for heterogeneity observed in depression. 相似文献

Bridging Science and Religion: How Health‐Care Workers as Storytellers Construct Spiritual Meanings 下载免费PDF全文
Contrary to the notion that medical science has supplanted religious understandings of human suffering, recent research suggests that health‐care workers like nurses can still portray their confrontations with illness and death in spiritual terms through storytelling. However, scholars have yet to systematically analyze the rhetorical devices used to construct spiritual meanings. Drawing on a symbolic interactionist perspective, we theorize that front‐line health professionals can deploy various rhetorical devices to infuse their workplace interactions with a spiritual significance. We also propose novel fuzzy set analysis techniques for determining which configurations of devices are most important in developing spiritual meanings. This approach was illustrated by examining 173 stories elicited from nurses at a nonsectarian, teaching hospital about encounters at work that significantly impacted their understanding of spirituality. Consistent with our expectations, the way in which nurses tell stories about their experiences not only shapes whether they attach spiritual significance to them, but whether they perceive spirituality and medicine to be compatible. We discuss the implications of our findings for future research on lived religion, conflicting identities, and institutional boundaries. 相似文献

There is a dearth of suitable metrics capable of objectively quantifying motor competence. Further, objective movement quality characteristics during free play have not been investigated in pre-school children. The aims of this study were to characterize children's free play physical activity and investigate how gait quality characteristics cluster with free play in pre-school children (3–5 years old). Sixty-one children (39 boys; 4.3 ± 0.7 years, 1.04 ± 0.05 m, 17.8 ± 3.2 kg) completed the movement assessment battery for children and took part in free play while wearing an ankle- and hip-mounted accelerometer. Characteristics of movement quality were profiled using a clustering algorithm. Spearman's rho and the Mann-Whitney U tests were used to assess relationships between movement quality characteristics and motor competence classification differences in integrated acceleration and spectral purity, respectively. Significant differences were found between motor competency classifications for spectral purity and integrated acceleration (p < .001). Spectral purity was hierarchically clustered with motor competence and integrated acceleration. Significant positive correlations were found between spectral purity, integrated acceleration and motor competence (p < .001). This is the first study to report spectral purity in pre-school children and the results suggest that the underlying frequency component of movement is clustered with motor competence. 相似文献

AbstractIn intervention studies having multiple outcomes, researchers often use a series of univariate tests (e.g., ANOVAs) to assess group mean differences. Previous research found that this approach properly controls Type I error and generally provides greater power compared to MANOVA, especially under realistic effect size and correlation combinations. However, when group differences are assessed for a specific outcome, these procedures are strictly univariate and do not consider the outcome correlations, which may be problematic with missing outcome data. Linear mixed or multivariate multilevel models (MVMMs), implemented with maximum likelihood estimation, present an alternative analysis option where outcome correlations are taken into account when specific group mean differences are estimated. In this study, we use simulation methods to compare the performance of separate independent samples t tests estimated with ordinary least squares and analogous t tests from MVMMs to assess two-group mean differences with multiple outcomes under small sample and missingness conditions. Study results indicated that a MVMM implemented with restricted maximum likelihood estimation combined with the Kenward–Roger correction had the best performance. Therefore, for intervention studies with small N and normally distributed multivariate outcomes, the Kenward–Roger procedure is recommended over traditional methods and conventional MVMM analyses, particularly with incomplete data. 相似文献
