The aim of this study was to explore whether children with and without learning difficulties use orthographic rules to write words. To study this, two types of tasks from the Early Grade Writing Assessment (EGWA) test were used: (1) a dictation task which included pseudowords with an implicit orthographic rule; and (2) a dictation task which included words with arbitrary, unregulated orthography. An initial sample of 1,447 students from grades 1 to 3 of elementary school was selected. The results showed that the variables task type and grade were significant when explaining the differences found between the groups. These findings are discussed from the perspective of the orthographic representations self-teaching hypothesis as related to the orthographic depth hypothesis, associated with the orthographic transparency of Spanish. 相似文献

Two studies of therapeutic communication and popularity were conducted in the framework of Dialogic Action Therapy (Ho & Wang, 2009) that accords centrality to the bidirectional nature of interpersonal perceptions. Pooled peer ratings, self-ratings, and estimates of peer ratings were collected from 88 Chinese students in psychology who knew one another well. Self-inflation was operationally defined as the self-rating minus the peer rating, and overestimation as the estimated rating minus the peer rating, for each participant; negative values would be indicative of self-deflation or underestimation. Major results are: (a) Pooled peer ratings have superior validity over self-ratings of therapeutic communication; (b) bias effects (above-average and self-deflation) are found in ratings of popularity; (c) self-inflation and overestimation decrease as pooled peer ratings of therapeutic communication increase and, similarly, self-inflation decreases as pooled peer ratings of popularity increase. These results strengthen the case for a relational methodological approach that includes assessing how one views oneself and others, how one is viewed by others, and discrepancies between perceptions. 相似文献

To understand the Invar anomalies, such as negative thermal expansion and spontaneous magnetization, we have applied our recently developed thermodynamic framework for a system with itinerant-electron magnetism to the ordered Fe3Pt. The framework has coherently predicted the finite temperature intermixing between the fully ferromagnetic (FM) configuration and the spin-flipping configurations (SFCs). We have also discovered a tri-critical point at which a high-temperature second-order phase transition, between the fully ordered FM phase and the paramagnetic phase which is disordered due to SFCs, becomes first order at low temperatures. 相似文献

Magnesium oxide (MgO) films and particles have been collected by pressurised filtration of a Mg-8.6wt%Al-0.67wt%Zn (AZ91D) alloy melt. The morphology of the oxides and their interfaces with the α-Mg phase were investigated by high-resolution transmission electron microscopy. It was found that the oxide films consisted of large numbers of sub-micrometre-sized MgO particles, and that melt shearing can effectively break up the oxide films and disperse the oxide particles. For the first time, orientation relationships (ORs) of OR I: [1?1?1]MgO~2° from (0?0?0?1)α-Mg and (0?1?1)MgO?//[2?1?1?0)α-Mg; and OR II: (1?1?1)MgO//(1?1?0?1)α-Mg and [0?1?1]MgO//[1?2?1?1]α-Mg, were observed between the MgO particles and the α-Mg matrix. The calculated Bramfitt planar disregistries were 5.5% and 2.5% for the two ORs, respectively, indicating good lattice matching between MgO and α-Mg at the interface. With the evidence of grain refinement effect observed in the sheared AZ91D magnesium alloy, the possibility of MgO particles to act as potent nucleants for heterogeneous nucleation of α-Mg grains is discussed in terms of the crystallographic criterion. 相似文献

主观幸福感的结构及其与人格特质的关系 总被引:19,自引:1,他引:19
以239名大学生为被试,考察了主观幸福感(SWB)的结构及其与人格特质的关系。分析表明,SWB由生活满意度、积极情感和消极情感三个相关的维度构成,而且它们可以共同负荷于一个高阶因子。外倾和神经质是SWB的重要预测指标,积极情感的主要预测指标是外倾,神经质则是消极情感最有力的预测指标,而外倾和神经质对消极情感和生活满意度有相同的预测力。情感平衡是外倾和神经质影响生活满意度的中介变量。 相似文献

Negative information processing biases have been hypothesised to serve as precursors for the development of depression. The current study examined negative self-referent information processing and depressive symptoms in a community sample of adolescents (N = 291, Mage at baseline = 12.34 ± 0.61, 53% female, 47.4% African-American, 49.5% Caucasian and 3.1% Biracial). Participants completed a computerised self-referent encoding task (SRET) and a measure of depressive symptoms at baseline and completed an additional measure of depressive symptoms nine months later. Several negative information processing biases on the SRET were associated with concurrent depressive symptoms and predicted increases in depressive symptoms at follow-up. Findings partially support the hypothesis that negative information processing biases are associated with depressive symptoms in a nonclinical sample of adolescents, and provide preliminary evidence that these biases prospectively predict increases in depressive symptoms. 相似文献

Stigma appears to influence emotional distress and well-being in cancer survivors, but cross-cultural differences have been ignored. Previous studies suggest that stigma may be especially relevant for survivors of Asian origin. However, their study designs (e.g. focused on female cancers, qualitative designs, and an absence of comparison groups) limit the strength of this conclusion. We hypothesized that (1) Asian-born Chinese immigrants (AI) would report more perceived cancer-related stigma than Western-born Caucasians (WBC); and (2) the impact of stigma on emotional distress and well-being would be greater in AI as compared to WBC. Head and neck cancer survivors (n = 118 AI and n = 404 WBC) completed measures of well-being, emotional distress, and a three-item indicator of stigma in structured interviews. The majority of respondents (59%) reported one or more indicators of stigma. Stigma correlated significantly with emotional distress (r = .13, p = .004) and well-being (r = ?.09, p = .032). Contrary to our hypotheses, WBCs and AIs did not differ in reported stigma nor did we detect differences in its psychosocial impact. Stigma exerts a deleterious psychosocial impact on head and neck cancer survivors. It did not differ significantly between AI and WBC survivors. 相似文献
