Preschoolers' cognitive level and locus of control orientation and their parents' locus of control orientation were considered as possible predictors of children's abilities to differentiate between safe and unsafe situations (safety score) and specify preventive measures (prevention score). Individual interviews were conducted with 3- to 6-year-old children enrolled at a daycare center, and their parents completed the Rotter Internal-External Locus of Control and the Accident Locus of Control (ALOC) scales. As hypothesized, children's level of causal reasoning was positively correlated with their safety and prevention scores. A curvilinear relationship was evident relationship existed with prevention score. Fathers' ALOC score was the only parent measure that predicted children's safety score, while none of the parent measures were predictive of children's prevention score. The findings were discussed in terms of safety education programs and directions for future research. 相似文献

以儿童抑郁量表为研究工具,对小学3到4年级771名儿童进行了2年的追踪研究。采用潜类别增长模型和终端结局潜发展模型,分别考察了童年期儿童抑郁情绪发展的亚群组类型,以及儿童抑郁情绪的发展特征对观察期结束时抑郁情绪的预测作用。结果表明:(1)童年期儿童的抑郁情绪发展呈现出三种不同的亚类型,即抑郁高风险组、抑郁低风险组和抑郁自愈组,各类型组人数比例分别为9.6%、53.4%和36.8%;(2)童年期儿童抑郁情绪的初始水平及其发展变化率均可以显著预测观察期结束时的抑郁情绪状况。童年期儿童抑郁情绪的早期监测工作有着重要的实践意义。 相似文献

以甘肃省陇南市成县6所幼儿园301名农村幼儿及其母亲为研究对象,采用流调中心抑郁量表(CES-D)、母亲教养方式量表和Achenbach儿童行为量表(CBCL)分别考察母亲抑郁、母亲回应性和幼儿社交退缩的现状及相互关系。主要结果如下:(1)西北农村地区母亲抑郁发生率较高,父亲外出打工和贫困家庭的母亲抑郁发生率更高;(2)母亲抑郁与幼儿社交退缩行为显著正相关,母亲抑郁水平越高,幼儿社交退缩得分越高;(3)母亲敏感性和反应性与幼儿社交退缩显著负相关,母亲敏感性和反应性得分越高,幼儿社交退缩得分越低;(4)母亲反应性在母亲抑郁和幼儿社交退缩之间起部分中介作用。 相似文献

A case history is presented of a four and-a-half year-old electively mute child who was successfully treated by the authors. The treatment approach involved paradoxical interventions in the context of a polarization model of cotherapy in combination with behavioral techniques in a family therapy framework. 相似文献

Orientation-specificity in kinesthetic spatial learning: The role of multiple orientations 总被引:2,自引:0,他引:2
In the current study we tested whether multiple orientations in kinesthetic learning affected how flexibly spatial information is stored and later used in making location judgments. Three groups learned simple routes by walking them while blindfolded, with (1) multiple orientations achieved through normal walking, (2) multiple orientations achieved through backward walking, or (3) a single orientation achieved through walking without turning (which required forward, backward, and sideways walking). When subjects had experienced multiple orientations while learning the routes, later directional judgments were equally accurate (and equally rapid) regardless of whether the judgments were aligned or were contra-aligned with the orientation of the routes as originally learned. In contrast, when routes were learned in a single orientation (without turning), subsequent judgments on contra-aligned trials were both less accurate and slower than judgments on aligned trials. Thus, multiple orientations are important to establish orientation-free, flexible use of spatial information in a kinesthetic learning environment. This contrasts with the pattern of results typically found in visual spatial learning and suggests that the factors that affect orientation specificity of spatial use may differ across spatial modality. 相似文献

A conceptual framework for the examination of alcohol and drug use as employee responses to work environments is proposed. Three sets of substance use antecedents are discussed. These are distancing forces, attractions, and constraints. Examples of these antecedents within the organizational setting are provided, and the dynamic interrelationships among them explored. Conditions for the use of different types of substances are also identified. 相似文献

A case of pure alexia due to an ischemic lesion of the occipital temporal region is described. Written words could be matched but not read. Immediate memory span for graphemes was defective. The reading defect probably depends on the inability to modify the written word “globally”; the phonological process was intact, but the memory disturbance impeded reading. The dissociation is explained by the preservation of word forms, which are linked to the semantic stage. Nonwritten stimuli trigger a “meaning” which evokes the word form and so the written word is recognized even though it cannot be read. 相似文献

問題 如果在构成閃光的相互交替的亮与黑两个时相中,黑时相不是完全黑,而是亮度不同程度的变暗,人們照样能看出閃光。暗时相的光強可以低到零,这就是一般閃光;但其光強也可以象亮时相一样高,那就变成了固定灯光。我們把一切強度的暗时相統称为“光坪”或“坪”,而把亮吋相叫作“光峯”或“峯”。 关于光坪对閃光信号辨认的影响的問題,是有关业务部門提出来的。根据我們的現場調查,使用者对某些带光坪的閃光信号的試用反应良好。我們前一研究表明,在实驗給定条件下,不宜使用两个同时性閃光,作为类似該实驗所用編碼的信号;同时提出“不 相似文献

An experimental test was made of two hypotheses formulated to account for age differences across adolescence in the learning of arbitrary associations. One hypothesis ascribes such differences to two factors: the propensity to elaborate coherent relationships among initially disparate items, and accessibility to event knowledge that can form the bases of such relationships. The other hypothesis assumes that propensity remains constant across age, and that development stems entirely from increases in the accessibility of relevant event knowledge. These hypotheses are evaluated with reference to the performance of 11- and 17-year-olds in learning relationships among paired nouns. The results discredited both hypotheses, instigating the formulation of a revised conception of the relationship between knowledge and propensity as developmental determinants. 相似文献
