本研究采用《幼儿数感测评量表》对26名自闭症谱系障碍(autism spectrum disorders,ASD)幼儿、20名智力障碍幼儿及32名正常幼儿进行数感能力测评,并比较三组幼儿的数感特点。结果发现:(1)ASD幼儿的数感整体和各维度水平均显著低于正常幼儿,但与智力障碍幼儿相当;(2)三组幼儿数感各维度水平在5~7岁之间无明显变化;(3)三组幼儿在数量比较、数量估算和大小比较的能力水平均领先于其他维度,而类比推理和大小推理均相对落后。另外,ASD幼儿和智力障碍幼儿的体积比较与大小推理、类比推理的能力较为接近,而正常幼儿的体积比较能力显著优于大小推理和类比推理。研究表明5~7岁ASD幼儿的数感能力整体落后于同龄正常幼儿,且数感各维度的能力发展不均衡、不同步。本研究揭示了5~7岁ASD幼儿数感能力发展的特点及需求,可为制定相应数感干预方案、促进其数学学习提供参考。  相似文献

The Bullying Participant Behaviors Questionnaire (BPBQ) is an efficient self-report measure for investigating bullying participant role behaviors. The present study evaluated the psychometric properties of the BPBQ in a Chinese middle school sample. A total of 516 middle school students (47.7% girls; age range?=?12–14 years) were recruited from an urban middle school in China. Results revealed that a five-factor model fit the data best. Correlations between the BPBQ subscale scores and the external criterion variables, including empathy and sympathy, moral disengagement, and trait anger, provided evidence of criterion validity. Furthermore, the BPBQ had good alpha reliability and moderate to good test-retest reliability. In conclusion, the BPBQ is a promising assessment tool to measure bullying participant behaviors among Chinese middle school students.

Previous studies found that individuals with promotion focus are more likely to be persuaded by messages framed in terms of gain‐related words; individuals with prevention focus are more likely to be persuaded by messages framed in terms of loss‐related words. This is known as the message matching effect of regulatory focus. The present study extended this effect into the field of moral judgement of other‐orientation lies. Two experiments were conducted, revealing that (a) individuals with promotion focus judged gain‐framed other‐orientation lies to be more moral, while individuals with prevention focus judged non‐loss‐framed other‐orientation lies to be more moral; and (b) the subjective processing fluency had a partial mediating role in the message matching effect. Theoretical implications and future research directions were discussed.  相似文献

During sentence reading, low spatial frequency information afforded by spaces between words is the primary factor for eye guidance in spaced writing systems, whereas saccade generation for unspaced writing systems is less clear and under debate. In the present study, we investigated whether word-boundary information, provided by alternating colors (consistent or inconsistent with word-boundary information) influences saccade-target selection in Chinese. In Experiment 1, as compared to a baseline (i.e., uniform color) condition, word segmentation with alternating color shifted fixation location towards the center of words. In contrast, incorrect word segmentation shifted fixation location towards the beginning of words. In Experiment 2, we used a gaze-contingent paradigm to restrict the color manipulation only to the upcoming parafoveal words and replicated the results, including fixation location effects, as observed in Experiment 1. These results indicate that Chinese readers are capable of making use of parafoveal word-boundary knowledge for saccade generation, even if such information is unfamiliar to them. The present study provides novel support for the hypothesis that word segmentation is involved in the decision about where to fixate next during Chinese reading.  相似文献

对703名初中生(平均年龄14.30岁)进行问卷调查, 探讨了青少年歧视知觉、亲子依恋在家庭经济压力与青少年抑郁关系中的中介和调节作用。结果表明:(1)在控制了性别、年级后, 家庭经济压力对青少年抑郁具有显著的正向预测作用;(2)在家庭经济压力对抑郁的正向预测关系中, 歧视知觉起中介作用;(3)家庭经济压力通过歧视知觉对抑郁的中介作用受到亲子依恋的调节, 相对于亲子依恋水平较高的青少年, 中介效应仅在亲子依恋水平较低的青少年中显著。  相似文献

The electrophysiological correlates of successful insight problem solving (Chinese logogriphs) were studied in 18 healthy subjects using high-density event-related potentials (ERPs). A new experimental paradigm (learning-testing model) was adopted in order to make subjects find a solution on their own initiative rather than receive an answer passively. Results showed that Successful guessed logogriphs elicited a more positive ERP deflection (P200-600) than did Unsuccessful guessed logogriphs in the time window from 200 to 600 ms after onset of the stimuli. Subsequently Successful logogriphs elicited a more negative ERP deflection than did Unsuccessful logogriphs in the time windows of 1500-2000 ms (N1500-2000) and 2000-2500 ms (N2000-2500). Maps of the P200-600 showed strong activity in the midline parieto-occipital scalp regions. Dipole analysis localized the generator of P200-600 in the left superior temporal gyrus and parietotemporo-occipital cortex areas. The N1500-2000 and N2000-2500 had a distinct activation over left frontal scalp regions. Dipole analysis localized the generator of the N1500-2000 in the anterior cingulate cortex (ACC) and the N2000-2500 in the posterior cingulate cortex (PCC). This result indicates that the parietotemporo-occipital cortex areas might be involved in forming rich associations in the early stage of successful logogriph solving. Then, the ACC might play an important role in the breaking mental set and the forming of novel associations. At last, "Aha" feeling might activate the PCC.  相似文献

We examined the differential item functioning (DIF) of Rosenberg's (1965 ) Self‐Esteem Scale (RSES) and compared scores from U.S. participants with those from 7 other countries: Canada, Germany, New Zealand, Kenya, South Africa, Singapore, and Taiwan. Results indicate that DIF was present in all comparisons. Moreover, controlling for latent self‐esteem, participants from individualistic countries had an easier time reporting high self‐esteem on self‐competence‐related items, whereas participants from communal countries had an easier time reporting high self‐esteem on self‐liking items ( Tafarodi & Milne, 2002 ). After adjusting for DIF, we found larger mean self‐esteem differences between the countries than observed scores initially indicated. The suitability of the RSES, and the importance of examining DIF, for cross‐cultural research are discussed.  相似文献

糖皮质激素替代治疗目前是全身性感染和感染性休克治疗的主要手段之一。尽管理论上存在着相对性肾上腺功能不足和糖皮质激素抵抗,但是其具体机制和诊断手段并未充分廓清;同时感染性休克小剂量激素替代治疗也未能被最新的临床研究证实。有鉴于此,有必要针对激素替代治疗对预后影响进行更深入的基础与临床研究。  相似文献

毛泽东“实事求是”思想内涵的新维度   总被引:1,自引:0,他引:1  
毛泽东的“实事求是”思想作为中国共产党的思想路线主要是认识论意义上的内涵,仅在认识论的意义上理解“实事求是”就会遇到理论和实践上难以解释的困惑。按照生活实践的观点重新理解“实事求是”,就会发现其中还蕴涵着价值论和道德论内涵。毛泽东“实事求是”思想的实践主体是中国共产党人,这一思想当中蕴含的价值论与道德论内涵具有特殊的内容。揭示毛泽东“实事求是”思想的价值论和道德论内涵对于更好地坚持实事求是具有重要意义。  相似文献
