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 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

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

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

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

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

Many studies have reported that individuals frequently over- or underestimate their risk of developing cancer both before and after they attend genetic counseling for breast and/or ovarian cancer. Using a combination of interviews and written questionnaires, we investigated counselees' understanding of their risk of developing cancer before and after genetic counseling. We demonstrate that although 76% of the sample thought that their risk was elevated relative to women in general, only a small proportion (17%) were willing or able to provide a numerical estimate of their risk of developing cancer before they attended the clinic. Following the consultation, 43% indicated that their risk of developing cancer was lower than they had anticipated. Twenty-two percent described their risk in absolute rather than relative terms, i.e., that they would definitely (not) develop cancer in the future. The implications of these findings for further research are discussed. 相似文献

In familial breast/ovarian cancer, the information that the proband is able to supply about other family members is of critical importance for genetic counseling. This frequently requires family communication. Forty-six women attending a cancer genetics clinic were interviewed as part of a longitudinal study. Nearly all reported affected maternal, rather than paternal relatives, which may indicate lack of awareness by women with paternal histories. There was also much more communication among female relatives. Mothers, where they were still alive, were key figures in supplying family information. Although the majority of the sample contacted at least one relative regarding counseling, most named a relative with whom they did not feel able to communicate on this subject. Probands balanced the perceived obligation of passing on information with that of not causing alarm. Communication, both obtaining and giving information, was impeded by adoption, divorce and remarriage, family rifts, and large age gaps between siblings. 相似文献

Discovering that participants who received therapy in a research project and were being debriefed in a therapy outcome study considered those assessment sessions therapeutic, the authors conclude that participants: (a) are aware of the research context, (b) have some idea about how it affected the treatment they got, and (c) see positive outcomes for taking part in the study. Assessment and treatment were not separated in the minds of some participants, as they had been in the mind of the researchers.This study was supported in part by National Institute on Drug Abuse grant #1R 18DA 1069232001. 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
