Research demonstrates that within‐category visual variability facilitates noun learning; however, the effect of visual variability on verb learning is unknown. We habituated 24‐month‐old children to a novel verb paired with an animated star‐shaped actor. Across multiple trials, children saw either a single action from an action category (identical actions condition, for example, travelling while repeatedly changing into a circle shape) or multiple actions from that action category (variable actions condition, for example, travelling while changing into a circle shape, then a square shape, then a triangle shape). Four test trials followed habituation. One paired the habituated verb with a new action from the habituated category (e.g., ‘dacking’ + pentagon shape) and one with a completely novel action (e.g., ‘dacking’ + leg movement). The others paired a new verb with a new same‐category action (e.g., ‘keefing’ + pentagon shape), or a completely novel category action (e.g., ‘keefing’ + leg movement). Although all children discriminated novel verb/action pairs, children in the identical actions condition discriminated trials that included the completely novel verb, while children in the variable actions condition discriminated the out‐of‐category action. These data suggest that – as in noun learning – visual variability affects verb learning and children's ability to form action categories. 相似文献

采用眼动技术,通过两个实验探讨人工语言标签与真实语言标签在类别学习中的作用。实验一对33名大学本科被试施测,探讨了人工语言标签对类别学习的影响。结果发现,在人工语言标签下,个体会基于标签的相似性进行分类。实验二对34名大学本科被试施测,探讨了真实语言标签对类别学习的影响。结果发现,在真实语言标签下,个体会基于标签的类别知识进行分类。类别学习中语言标签效应的熟悉程度影响分类方式,不熟悉的类别语言标签基于相似性分类,熟悉的类别语言标签基于知识分类;基于类别知识分类准确性更高,速度更快。 相似文献

The effects of vocal intraverbal training and listener training on the emergence of untrained categorization skills were evaluated. Five typically developing preschool children initially learned to name a number of previously unfamiliar visual stimuli. Each child then received one of two types of training. Intraverbal training involved reinforcing vocally emitted category names by the child in the presence of a spoken exemplar name. Listener training involved reinforcing the selection of visual stimuli by the child in the presence of a spoken category name. A multiple baseline design was used to evaluate the effects of training on each child's intraverbal category naming and stimulus selection. Pre- and posttests were used to assess additional emergent relations. Four of 5 participants did not demonstrate the emergence of any untrained relations. The current findings suggest that additional research is needed to determine the optimal sequencing of conditions in programs designed to teach categorization skills. 相似文献

Cyberbullying: Another main type of bullying? 总被引:2,自引:0,他引:2
Cyberbullying has recently emerged as a new form of bullying and harassment. 360 adolescents (12-20 years), were surveyed to examine the nature and extent of cyberbullying in Swedish schools. Four categories of cyberbullying (by text message, email, phone call and picture/video clip) were examined in relation to age and gender, perceived impact, telling others, and perception of adults becoming aware of such bullying. There was a significant incidence of cyberbullying in lower secondary schools, less in sixth-form colleges. Gender differences were few. The impact of cyberbullying was perceived as highly negative for picture/video clip bullying. Cybervictims most often chose to either tell their friends or no one at all about the cyberbullying, so adults may not be aware of cyberbullying, and (apart from picture/video clip bullying) this is how it was perceived by pupils. Findings are discussed in relation to similarities and differences between cyberbullying and the more traditional forms of bullying. 相似文献

A critical issue in perception is the manner in which top-down expectancies guide lower level perceptual processes. In speech, a common paradigm is to construct continua ranging between two phonetic endpoints and to determine how higher level lexical context influences the perceived boundary. We applied this approach to music, presenting participants with major/minor triad continua after brief musical contexts. Two experiments yielded results that differed from classic results in speech perception. In speech, context generally expands the category of the expected stimuli. We found the opposite in music: The major/minor boundary shifted toward the expected category, contracting it. Together, these experiments support the hypothesis that musical expectancy can feed back to affect lower-level perceptual processes. However, it may do so in a way that differs fundamentally from what has been seen in other domains. 相似文献

应用EyelinkⅡ眼动仪, 通过两项消失文本实验分别考察了汉语阅读过程中眼跳的目标选择单元以及词汇加工方式。实验一操纵注视点上字和词的呈现方式, 发现中文读者以词为基本单元对注视点及其右侧文本信息进行加工, 且保持词的视知觉完整性对词内再注视眼跳和词间眼跳都有着非常重要的作用; 汉语阅读的眼动模式符合认知控制模型的预测。实验二操纵注视点左侧和右侧单词的呈现与消失, 结果显示在对词n注视持续50~55 ms后词n-1消失将严重影响被试的阅读, 词n+1和词n+2的消失均不影响总阅读时间, 但会导致读者的眼动模式发生改变, 说明中文读者可以并列加工阅读知觉广度内的词汇。 相似文献

Examined the effects of incidental sadness and anger on affiliative responses to crossed categorization targets. Affect manipulations included an anger-provoking frustration (Study 1), a sad film clip (Study 2), and autobiographical essays about sad or anger-provoking topics (Studies 3 and 4). By comparison with a neutral mood, anger (Study 1) reduced affiliative tendencies toward persons possessing an out-group membership but not toward those possessing only in-group memberships. Study 2 showed a similar pattern for sadness. Studies 3 and 4 replicated these effects in designs including both types of negative mood. Meta-analytic integration showed the pattern of greater rejection of targets with an out-group membership to be stronger under anger than sadness. Study 4 also showed that despite yielding a consistent pattern for affiliation, sadness and anger differentially elicited aggressive tendencies toward the same targets. 相似文献

This article analyses two ‘digital Bibles’, products that allow the user to engage with the Bible through the screen and speakers of his/her mobile phone, tablet or computer. Both products, ‘YouVersion’ and ‘GloBible’, have been created by Evangelical Christian companies. I argue that both are designed to train the user in traditional Evangelical Christian understandings of the work of reading. Digital media offer new opportunities to guide and influence the user, and this article applies the concepts of ‘persuasive technologies’ and ‘procedural rhetoric’ to analyse the design intentions of the two digital Bibles. This approach helps us to appreciate the significance of the material form of a sacred text as a vehicle for religious socialisation and raises important questions about the potential for digital media to re-shape traditional relationships of power in Evangelical Christian communities. 相似文献

The role of dual categorization and relative ingroup prototypicality in reparations to a minority group: An examination of empathy and collective guilt as mediators 下载免费PDF全文

In the current study, we investigate factors that facilitate or otherwise obstruct reparations of a perpetrating group (i.e. Muslims) to a victim group (i.e. Christians). The study (N = 200) reveals that among Muslim participants, the role of dual Abrahamic categorization in positively predicting reparation attitude towards Christians was mediated by the first group's prosocial emotions of empathy and collective guilt towards the latter group. In addition, relative Muslim prototypicality negatively predicted dual Abrahamic categorization and each of the two prosocial emotions. Empathy and collective guilt in turn mediated the role of relative ingroup prototypicality in negatively predicting reparation attitude. Moreover, as hypothesized, we found that the roles of empathy and collective guilt in predicting reparation intention, as manifested in participants' willingness to engage in collective action on behalf of the victim group, were not significant on their own, but were mediated by reparation attitude. These findings shed light on the importance of the relationship between the perpetrating group's shared identity with the victim group, reduced ingroup focus and its support for making reparations to the victim group. Theoretical implications, study limitations and practical strategies highlighting how to decrease relative Muslim prototypicality are discussed. 相似文献
