The effect of geographic indication in advertising background pictures on product evaluation: The moderating role of familiarity 下载免费PDF全文
This study investigates whether geographic indications in the backgrounds of advertising pictures might affect the viewer's evaluation of a product. The findings reveal that participants in the proximal geographic indication evaluated the product more favourably than those in the distal geographic indication when they were exposed to feasibility‐related information. By contrast, participants in the distal geographic indication evaluated the product more favourably than those in the proximal geographic indication when they were exposed to desirability‐related information. However, familiarity with geographic indications eliminated this effect. 相似文献

School Substance Use Norms and Racial Composition Moderate Parental and Peer Influences on Adolescent Substance Use 下载免费PDF全文
Parental and peer influences on adolescent substance use have been well demonstrated. However, limited research has examined how parental and peer influences vary across school contexts. This study used a multilevel approach to examine the effects of school substance use norms and school racial composition in predicting adolescent substance use (a composite measure of alcohol, tobacco, and marijuana use) and in moderating parental and peer influences on adolescent substance use. A total of 14,346 adolescents from 34 schools in a mid‐western county completed surveys electronically at school. Analyses were conducted using hierarchical linear modeling. Results indicated that school‐level disapproval against substance use and percentage of minority students at school were negatively associated with adolescent substance use. School‐level disapproval moderated the association between peer substance use and adolescent substance use, with the association being stronger when school‐level disapproval was lower. School racial composition moderated the influence of parental disapproval and peer substance use on adolescent substance use. Specifically, both the association between parental disapproval and adolescent substance use and the association between peer substance use and adolescent substance use were weaker for adolescents who attended schools with higher percentages of minority students. Findings highlighted the importance of considering the role of school contexts, in conjunction with parental and peer influences, in understanding adolescent substance use. 相似文献

启动效应被严格界定为先前刺激对后续无关情境中的行为反应产生的无意识影响,而且启动对象应是某种认知表征或思维过程。启动研究最早源于认知心理学领域,后被用于社会心理学研究中,并逐渐发展出概念启动、心理定势启动和序列启动三大启动范式及诸多新技术。已有研究存在启动术语混淆和实验者效应等内外部效度问题,其中最大的争议为启动研究结果的可重复性问题。未来研究应致力于解决这些问题,并探讨启动的作用机制。 相似文献

研究采用同伴提名法、教师和家长报告法,对农村135名一年级小学生进行了为期一年的追踪调查,在此基础上,考察了学前教育年限、母亲受教育水平与学校适应之间的关系。结果表明:(1)学前教育年限越长,小学生越多地表现出积极社会行为,但这种优势仅体现在小学入学初期;(2)母亲受教育水平越低,小学生越多地表现出敏感退缩行为和受拒绝同伴关系;(3)对于母亲受教育水平较低的小学生,学前教育年限越长,其攻击冒犯行为越多;而对于母亲受教育水平较高的小学生,学前教育年限越长,其攻击冒犯行为越少。可见,母亲受教育水平与学前教育年限相互作用,共同影响儿童发展结果,且母亲受教育水平的影响作用更为明显。 相似文献

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明:(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用:在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。 相似文献

Stimuli in many visual stimulus control studies typically are presented simultaneously; in contrast the stimuli in auditory discrimination studies are presented successively. Many everyday auditory stimuli that control responding occur simultaneously. This suggests that simultaneous auditory discriminations should be readily acquired. The purpose of the present experiment was to train rats in a simultaneous auditory discrimination. The apparatus consisted of a cage with two response levers mounted on one wall and a speaker mounted adjacent to each lever. A feeder was mounted on the opposite wall. In a go-right/go-left procedure, two stimuli were presented on each trial, a wide-band noise burst through one speaker and a 2-kHz complex signal through the other. The stimuli alternated randomly from side to side across trials, and the stimulus correlated with reinforcement for presses varied across subjects. The rats acquired the discrimination in 400 to 700 trials, and no response position preference developed during acquisition. The ease with which the simultaneous discrimination was acquired suggests that procedures, such as matching to sample, that require simultaneous presentation of stimuli can be used with auditory stimuli in animals having poor vision. 相似文献

对幼儿从电视中伴随学习单词的可能性及其影响因素进行了初步的探讨。40名小班幼儿和46名大班幼儿参加了实验,他们在接近自然的状态下观看有字幕的动画片。结果发现:幼儿在无任何指导的情况下观看有字幕的动画片,能伴随学习到汉字,这表明,电视对幼儿的词汇发展有着积极的影响;不同性别的儿童都能同等程度地从电视中伴随学习到单词;词义的伴随学习受幼儿原有的词汇水平和幼儿对目标词熟悉程度的影响;词音的伴随学习只发生在词汇水平较高的幼儿当中,并且随着幼儿对目标词熟悉程度的增加而增加;词音和词义的伴随学习存在频度效应。 相似文献
