物体识别的两大理论一直存在争议。以物体为中心理论认为不管物体出现在什么位置,识别均与空间位置无关,而以观察者为中心理论认为识别与空间位置有关。研究参照物体识别的“小几何体”思想自制实验材料,采用启动范式下的分类任务,通过操纵物体自身的结构信息和相对的结构信息,考察了三维物体识别的影响机制。结果发现:(1)物体自身组成部分之间的分离水平和物体之间的相对空间位置对物体识别的影响均呈层级式。支持以观察者为中心理论的整体表征观;(2)不分离水平和相同位置上,整体启动快于部分启动;全分离水平和远距离位置上,部分启动快于整体启动。支持以物体为中心理论的小几何体优先加工观。实现两大理论的融合需要进一步厘清“What + Where”两通路联合表征的二级子层级。 相似文献

The seminar on anxiety marks a turning point in the development of Lacan's thought from several perspectives. First, Lacan implicitly abandons his theory that the unconscious is structured like a language. He also abandons the endeavour to identify Freud's theory with his own. He develops some original new ideas about anxiety, some of which are of great interest, such as the connection between castration anxiety and narcissism; others, such as his denial of the existence of separation anxiety, are absurd. Lacan's main point of divergence from Freud, his rejection of the inner world, also emerges clearly in this seminar. 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

Following the emergence of two four-member equivalence classes (A1B1C1D1 and A2B2C2D2), 5 students were exposed to a series of phases including a baseline conditional discrimination reversal (i.e., choosing D2 was reinforced and D1 punished given Sample A1; choosing D1 was reinforced and D2 punished given Sample A2), the delayed introduction of CD/DC transitivity/equivalence probes, DE conditional discrimination training, a second baseline conditional discrimination reversal (i.e., choosing C2 was reinforced given B1, etc.), and a return to original baseline reinforcement contingencies. Results showed that baseline and symmetry probe performances were extremely sensitive to baseline modifications. In contrast, patterns on transitivity/equivalence probes remained predominantly consistent with the originally established equivalence classes, although there were exceptions on some E probe relations for 2 subjects. The dissociation between baseline and symmetry versus transitivity/equivalence patterns may have important implications because it is not easily accounted for by current models of equivalence phenomena. 相似文献

Theory and research on social support have paid little attention to the existence of important macrosocial variables determining level and content of social relationships. This study examines variations in social integration as a function of social class and residential area characteristics. Results for 234 subjects living in high and low risk neighbourhoods indicated that differences between higher and lower social class groups follow different patterns in different residential areas. Also, same social class position appeared to have different significance as a function of residential area characteristics. The levels of three social integration measures—community integration and satisfaction, community association and participation, and contribution in community organizations—were significantly higher for lower class in low risk neighbourhoods than in high risk ones. However, significant differences were found in only one measure for higher social class groups, with higher levels of community association and participation in high risk neighbourhoods than in low risk ones. The discussion examines a ‘social impoverishment’ hypothesis for high risk environments, and proposes possible protective factors for higher status residents. Relations between formal and informal sources of support, and implications for social intervention strategies are also considered. 相似文献

Generic chaplaincy is the result of a devaluing of religiousworship and belief to the merely instrumental and experiential.It is an expectable consequence of non-belief in the uniqueobject that would render religious worship intrinsically meaningfuland valuable. Generic chaplaincy has no place because all desireGod, yet not all have found Him in the fullness with which Hehas revealed Himself to us, or even in the fullness with whichwe may be aware of Him through natural reason. In consequence,not all are equally aware of God. A chaplaincy that challengespatients respectfully, and encourages spiritual growth and awareness,including the overcoming of sin and error, is appropriate. 相似文献

本文采用一种新的偏好诱导方法——实物交换方法 ,对偏好反转中的兼容性假设进行实验验证。实验结果支持兼容性假设 ,并发现了一种新的现象 ,即偏好反转的倒置现象。偏好反转与偏好反转的倒置相映成趣 ,为解释风险决策中偏好反转的兼容性假设提供了充足的证据 ,也对风险决策中的纯粹理性提出了更多的挑战。 相似文献
