This paper explores the relation between an unknown place name written in hiragana (a Japanese syllabary) and its corresponding written representation in kanji (Chinese characters). We propose three principles as those operating in the selection of the appropriate Chinese characters in writing unknown place names. The three principles are concerned with the combination of on and kun readings (zyuubako-yomi), the number of segmentations, and the bimoraicity characteristics of kanji chosen. We performed two experiments to test the principles; the results supported our hypotheses. These results have some implications for the structure of the Japanese mental lexicon, for the processing load in the use of Chinese characters, and for Japanese prosody and morphology. 相似文献

This study examined the structure of negative emotions in a sample of nonclinical adolescents, using an approach that exclusively relied on child self-report. A large sample of adolescents (N = 968) completed self-report questionnaires measuring symptoms of fear, anxiety, and depression. Confirmatory factor analysis provided support for the notion that fear, anxiety, and depression are distinct yet correlated components of negative emotions. This result is in agreement with recent empirical findings and current theoretical notions on the structure of negative emotions in children and should be taken as an encouragement for researchers to develop more specific measures for assessing fear, anxiety, and depression in children. 相似文献

Most of the extant research on welfare reform has neglected to consider the experiences of families in rural settings. Fifty women receiving welfare for their dependent children in a rural community were interviewed about their work experiences and aspirations, barriers to employment and service use, as well as mental health and social support. The findings indicate that the majority of participants were connected to the labor force and expressed positive attitudes about work. Barriers to employment (lack of available jobs, child care) and service use (transportation, inconvenient office hours) were endorsed. Perceived social support was negatively related to depression symptoms and positively related to self-efficacy and self-esteem. The importance of understanding the life experiences of welfare recipients in different contexts is discussed. 相似文献

This paper reviews key findings on juvenile mental health problems in boys, psychopathy, and personality traits, obtained in the first 14 years of studies using data from the Pittsburgh Youth Study. This is a study of 3 samples, each of about 500 boys initially randomly drawn from boys in the 1st, 4th, and 7th grades of public schools in Pittsburgh. The boys have been followed regularly, initially each half year, and later at yearly intervals. Currently, the oldest boys are about 25 years old, whereas the youngest boys are about 19. Findings are presented on the prevalence and interrelation of disruptive behaviors, ADHD, and depressed mood. Results concerning risk factors for these outcomes are reviewed. Psychological factors such as psychopathy, impulsivity, and personality are described. The paper closes with findings on service delivery of boys with mental health problems. 相似文献

转型期初中生心理健康与父母养育方式的研究 总被引:38,自引:1,他引:37
本研究采用《心理健康诊断量表》和《父母养育方式问卷》对196名初中生进行测量,探讨初中生心理健康与父母养育方式的影响因素及其相互之间的关系。结果表明,初中生的心理健康问题的检出率依次是自责倾向、恐怖倾向、冲动倾向和对人焦虑;性别因素只在心理健康的学习焦虑、养育方式上的父亲的惩罚、严厉、母亲的过干涉、过保护、父母的拒绝、否认等因素上表现出了显著差异;独生子女与非独生子女子女比较,在恐怖倾向以及惩罚、严厉的养育方式上存在显著差异;父母的文化程度、职业状况、离异、下岗等因素,只有母亲的职业状况因素对心理健康构成了影响;父母消极的教养方式将使学生的焦虑增加,母亲积极的教养方式将使学生的焦虑减少。 相似文献

Contingent physical guidance was used to treat chronic aerophagia. This consisted of guiding the participant's hand over her mouth following each attempt to engage in aerophagia. A wristwatch was then correlated with the contingent physical guidance procedure. Responding remained low in the presence of the wristwatch, even after contingent physical guidance was withdrawn. 相似文献

The present study addressed limitations of a recent confirmatory factor analytic study challenging the hypothesized factor structure of the Beavers Interactional Scales. That dataset (n = 97) was reanalyzed and two additional datasets (n = 95, n = 91) were explored. With all three samples, taken separately and together, the Beavers Systems Model, when operationalized in the BIS, was not supported. A body of evidence is accumulating which suggests that clinicians and researchers should be wary of the BIS. 相似文献

A number of hypotheses have emerged regarding the etiology of physical aggression in persons with mental retardation. Although a multicomponent model is appropriate, results of functional analysis-based studies have yielded promising results in identifying instigating and maintaining factors of aggression. However, the relationship between functional variables and conditions such as psychiatric diagnosis to aggressive behavior has yet to be investigated in persons with mental retardation. We conducted a study examining the prevalence of environmental or physical factors in aggressive behavior in mentally retarded persons with and without psychiatric disturbance. One hundred and thirty-five individuals with mental retardation who exhibited physical aggression were assessed with the Questions About Behavior Function Scale (QABF) to identify environmental or physical contribution to aggressive behavior. One or more behavioral functions were identified for 75% of the participants. Additionally, of 66 of the participants scoring above the clinical cutoff on an assessment for dual diagnosis, 75% met criteria for an environmental or physical function for aggression. No significant differences in number of participants with an identifiable function of aggression were found between the no dual diagnosis and dual diagnosis groups. Our findings underscore the importance of identifying functions underlying aggressive behavior in persons with mental retardation, and the need to consider functional variables regardless of psychiatric condition in treatment planning efforts for such individuals. 相似文献

本研究以北京地区398名初中学生为被试,以适度睡眠、合理饮食、口腔卫生、体育锻炼、防止久坐五类健康促进行为与冒险、越轨、吸烟、过量饮酒、冒险骑车五类健康危害行为为对象,对其健康行为的因素结构特点进行了分析。研究结果表明,初中阶段青少年的健康危害行为间具有显著的正相关,而健康促进行为间的关系则较为复杂。验证性因素分析结果表明,初中阶段青少年健康行为的因素结构主要包含了两个因素,其中健康生活习惯因素主要包括适度睡眠、合理饮食与口腔卫生三类健康促进行为;冒险生活方式因素则包括了冒险、越轨、吸烟、过量饮酒、冒险骑车五类健康危害行为以及体育锻炼、防止久坐两类健康促进行为。 相似文献
