This study evaluated a device that applied a sustained increase in accelerator pedal back force whenever drivers exceeded a preset speed criterion without buckling their seat belts. This force was removed once the belt was fastened. Participants were 6 commercial drivers who operated carpet-cleaning vans. During baseline, no contingency was in place for unbuckled trips. The pedal resistance was introduced via a multiple baseline design across groups. On the first day of treatment, the device was explained and demonstrated for all drivers of the vehicle. The treatment was associated with an immediate sustained increase in seat belt compliance to 100%. Occasionally, drivers initially did not buckle during a trip and encountered the force. In all instances, they buckled within less than 25 s. These results suggest that the increased force was sufficient to set up an establishing operation to reinforce seat belt buckling negatively. Drivers indicated that they were impressed with the device and would not drive very long unbelted with the pedal force in place. 相似文献

We observed 11 undergraduates in an experiment designed to simulate infant caregiving. In negative reinforcement conditions experienced by all participants, a targeted caregiving response (e.g., rocking a baby doll) produced escape from, and avoidance of, a recorded infant cry. Nine participants' caregiving was shown to be controlled by this negative reinforcement contingency. Nine participants experienced an extinction condition that consisted of an inescapable cry, and the previously reinforced caregiving responses of 2 of these participants were resistant to extinction. For both of these participants, the previously reinforced response was eliminated when an alternative form of caregiving was reinforced. These results highlight the role of negative reinforcement in infant caregiving and suggest the need for additional research on the effects of crying on caregivers as well as the development of effective strategies for minimizing infant crying. 相似文献

本文根据埃里克森、玛西娅、加藤厚等人的自我同一性理论,对某中学初一至高三学生的自我同一性及情绪表达进行问卷调查研究。研究发现,中学生自我同一性发展各个维度总体呈"低-高-低-高"的发展趋势。高一是自我同一性发展的转折时期,在现在的自我投入上处于低谷,与其他各年级存在显著性差异。同时自我同一性度数分布也存在显著性差异。中学生的正性情绪表达在性别上存在显著差异。从初一至高三,学生的情绪表达三个维度都呈下降趋势,高二、高三学生的正性情绪表达、负性情绪表达、情绪表达强度显著低于初一、初二学生。中学生现在的自我投入和将来自我投入的愿望与正性情绪表达呈显著正相关。 相似文献

观点采择对人们加工情绪具有明显的影响。已有研究发现人们对负性情绪信息存在加工偏向, 且观点采择对外显情绪的加工具有调节作用。但观点采择如何影响内隐情绪的加工尚不清楚。为了考察观点采择对内隐情绪加工的影响, 当前研究要求被试分别通过自我视角和他人视角完成情绪图片(中性图片和负性图片)的形状辨别任务, 同时记录其脑电活动。成分分析的结果显示, 与他人视角条件相比, 自我视角条件下加工负性信息引发了更大的额部及中央的N200 (180~220 ms)和顶区的LPC (267~567 ms)波幅。相位锁定的时频分析结果显示, 刺激呈现后0 ms 至300 ms时间窗口内, 在自我视角条件下, 负性信息的加工引发了显著增大的theta (4~8 Hz)节律的能量活动。成分分析和时频分析的结果均表明, 自我视角条件对负性信息加工具有启动效应, 他人视角条件则抑制了对负性信息的加工, 说明观点采择对内隐情绪加工具有调节作用, 反映了人不仅能够区分环境中潜在的危险信息, 而且能通过观点采择区分自我与他人。 相似文献

探讨类别型状态不确定独立否定句(如“裙子不是蓝色的”)的动态表征过程。实验1和实验2分别仅给被试提供“与事件备择选项一致的图片” (红色裙子)和“含有否定标签的与事件否定状态一致的图片” (含有否定标签的蓝色裙子); 实验3同时提供以上两种选项。结果发现:3个实验中被试在早期均对“与事件否定状态一致的图片”注视概率更高, 在晚期阶段, 实验1仅对“与事件备择选项一致的图片” 注视概率更高, 实验2和实验3均仅对“含有否定标签的与事件否定状态一致的图片”注视概率更高, 并且选择为事件的最终状态; 实验4的评定结果表明, 当被试有充裕时间完成任务时, 37名评定者中有30名选择“与事件备择选项一致的图片”为事件的最终状态。4个实验的结果为锚激活与限制满足模型和抑制假设提供了进一步证据。 相似文献

本文基于关联习得理论, 探讨了模糊产品展示对产品态度的影响。结合4个实验的结果, 发现模糊产品展示对产品态度的影响呈现倒U型。相比于低模糊度的产品展示, 中等模糊度的产品展示能够激发更高水平的柔软度感知, 进而提升产品质量评价, 最终导致产品态度更积极。但过高模糊度的产品展示会激发消费者强烈的消极情绪, 消极情绪对产品态度的消极影响会抵消掉柔软度感知的积极影响, 最终导致产品态度的降低。 相似文献

Though acknowledged by scholars, Plato’s identification of the Beautiful and the Good has generated little interest, even
in aesthetics where the moral concepts are a current topic. The view is suspect because, e.g., it is easy to find examples
of ugly saints and beautiful sinners. In this paper the thesis is defended using ideas from Plato’s ancient commentators,
the Neoplatonists. Most interesting is Proclus, who applied to value theory a battery of linguistic tools with fixed semantic
properties—comparative adjectives, associated gradable adjectives, mass nouns, and predicate negations—all with a semantics
that demand a privative scale of value. It is shown how it is perfectly possible to interpret value terms Platonically over
privative Boolean algebras so that beautifuland good diverge while at higher levels other value terms are coextensional. Considerations are offered that this structure conforms
to actual usage. 相似文献

This paper will focus on the concept of 'absence', which describes a continuum of non-responsiveness and misattunement of the environment in the stage of absolute dependence; it refers to concepts like lack, failure, non-recognition, impingement, neglect, tantalizing, ranging to mental, physical and sexual abuse. An extreme external absence causes shock and fear. The automatic survival response is an inner absence, an intrapsychic absence, a dissociation of parts of the self. The external and the inner absence are the negative image of each other. The concept of absence points to the synchronicity of outer and inner reality and portrays the non-responded-to needs of the self. This point of view of the development of psychopathology of the self on the basis of massive dissociation is inherently an intersubjective-field-theory. As the inner absence is created as a reaction to an absence of the other, in analysis - the analyst has an active role in reviving it. This paper will explore the language of absence, that is, the derivatives and consequences of these situations in the inner realm, and in the relations with the analyst. It is the author's contention that understanding and speaking this language has important clinical and technical implications. Understanding the language of absence enables the analyst to recognize its intersubjective and its intrapsychic presence, to provide an environment that allows for its revival, and to facilitate and regulate the annihilation anxiety that awakens when dissociated self-states are experienced. When the absence is present, i.e. when the traumatic experience and the dissociated reactions to it are experienced in an attuned relationship, it is rendered with meaning, symbolization, and validation, and enables the survival mode of dissociation to be relinquished. 相似文献
