基线选择影响词语认知启动实验结果的研究 总被引:1,自引:0,他引:1
探讨了词语认知启动实验中,启动基线的选择问题。一项有关汉字识别中形音义激活时间进程的实验表明:是采用无关字启动还是采用图形符号启动作为衡量启动效应的基线,会对词语认知启动实验的结果产生不同的影响。根据本研究结果,对词语认知启动实验中基线的选择问题提出了建议。 相似文献

近年来,歧视研究领域中的"强势心理学"现象开始减弱,研究者们逐渐重视弱势群体自身对于歧视现象的知觉与反应.本文在整合歧视知觉相关领域研究成果的基础上,首先就歧视知觉的概念内涵、测量进行阐述;继而从"风险"与"弹性"两个方面,分别探讨歧视知觉的消极影响效应与间接性的积极影响效应;最后从整合的视角,对歧视知觉影响效应的内在机制——拒绝认同理论进行讨论.未来歧视知觉领域的研究将会进一步细化群体成员资格;重视考察个体和群体歧视知觉的作用差异;加强探讨个体水平的中介变量的作用;更多关注儿童群体的歧视知觉问题. 相似文献

Fifty-eight smokers received abstinence-contingent monetary payments for 1 (n = 15) or 14 (n = 43) days. Those who received contingent payments for 14 days also received 0, 1, or 8 experimenter-delivered cigarette puffs on 5 evenings. The relative reinforcing effects of smoking were assessed in a 3-hr session on the final study day, when participants made 20 choices between smoking or money. The reinforcement contingencies exerted robust control over smoking, and programmed smoking lapses produced few discernible effects. These results further illustrate the robust control that reinforcement contingencies can exert over cigarette smoking and suggest that any effects of lapses on the relative reinforcing effects of smoking are modest under conditions involving abstinence-contingent reinforcement contingencies. 相似文献

Although researchers have consistently found that neighborhoods matter, relatively little is known about the processes through which neighborhood-level characteristics influence individual outcomes, and whether interventions targeting improving neighborhood characteristics will be beneficial for children. I examine whether relocating from high- to low-poverty neighborhoods affected low-income Black children's exposure to promotive developmental experiences. Participating families voluntarily relocated from high-poverty, minority segregated, inner-city Chicago neighborhoods to mostly White, low-poverty, suburban and Chicago neighborhoods. Data come from retrospective qualitative interviews with 22 Gautreaux One families an average of 15 years after initial relocation, and from interviews with 43 Gautreaux Two families as they relocated into their new communities. I find that children primarily benefited from the institutional versus the social interaction resources in their new neighborhoods. Furthermore, suburban placement was key in facilitating children's access to higher quality resources. 相似文献

We tested whether children show greater internalizing symptoms when their parents are actively abusing alcohol. In an integrative data analysis, we combined observations over ages 2 through 17 from two longitudinal studies of children of alcoholic parents and matched controls recruited from the community. Using a mixed modeling approach, we tested whether children showed elevated mother- and child-reported internalizing symptoms (a) at the same time that parents showed alcohol-related consequences (time-varying effects), (b) if parents showed greater alcohol-related consequences during the study period (proximal effects), and (c) if parents had a lifetime diagnosis of alcoholism that predated the study period (distal effects). No support for time-varying effects was found; proximal effects of mothers' alcohol-related consequences on child-reported internalizing symptoms were found and distal effects of mother and father alcoholism predicted greater internalizing symptoms among children of alcoholic parents. Implications for the time-embedded relations between parent alcoholism and children's internalizing symptoms are discussed. 相似文献

Although bidirectional parent and child influences have been incorporated in theoretical models pertaining to the development of internalizing and externalizing behaviors in youth, studies have historically focused on the socializing influence that parents have on their children. This has left several important research questions unanswered about the nature of bidirectional parent-child relations across development, including how these bidirectional effects are related to different types of child and adolescent psychopathology. The goal of this special section is to examine some longstanding issues regarding the nature of bidirectional parent-child effects across time using a diverse array of longitudinal datasets. The results from these studies emphasize the importance of considering bidirectional effects in developmental psychopathology research, particularly the often overlooked influence that children and adolescents have on their parents' behavior and emotional well-being. Following these empirical articles, an expert in the field provides a scholarly commentary designed to outline the progress that has been made in understanding bidirectional parent-child effects across development as well as to propose fruitful areas for future research. 相似文献

In order to investigate whether the Lidcombe Program effects a short-term reduction of stuttered speech beyond natural recovery, 46 German preschool children were randomly assigned to a wait-contrast group or to an experimental group which received the Lidcombe Program for 16 weeks. The children were between 3;0 and 5;11 years old, their and both of their parents’ native language was German, stuttering onset had been at least 6 months before, and their stuttering frequency was higher than 3% stuttered syllables. Spontaneous speech samples were recorded at home and in the clinic prior to treatment and after 4 months. Compared to the wait-contrast group, the treatment group showed a significantly higher decrease in stuttered syllables in home-measurements (6.9%SS vs. 1.6%SS) and clinic-measurements (6.8%SS vs. 3.6%SS), and the same increase in articulation rate. The program is considered an enrichment of currently applied early stuttering interventions in Germany.
Educational objectives: Readers will discuss and evaluate: (1) the short-term effects of the Lidcombe Program in comparison to natural recovery on stuttering; (2) the impact of the Lidcombe Program on early stuttering in German-speaking preschool children. 相似文献
