There is converging evidence that infants are sensitive to prosodic cues from birth onwards and use this kind of information in their earliest steps into the acquisition of words and syntactic regularities of their target language. Regarding word segmentation, it has been found that English-learning infants segment trochaic words by 7.5 months of age, and iambic words only by 10.5 months of age [Jusczyk, P. W., Houston, D. M., & Newsome, M. (1999). The beginnings of word segmentation in English-learning infants. Cognitive Psychology, 39, 159–207]. The question remains how to interpret this finding in relation to results showing that English-learning infants develop a preference for trochaic over iambic words between 6 and 9 months of age [Jusczyk, P. W., Cutler, A., & Redanz, N. (1993). Preference for the predominant stress patterns of English words. Child Development, 64, 675–687]. In the following, we report the results of four experiments using the headturn preference procedure (HPP) to explore the trochaic bias issue in German- and French-learning infants. For German, a trochaic preference was found at 6 but not at 4 months, suggesting an emergence of this preference between both ages (Experiments 1 and 2). For French, 6-month-old infants did not show a preference for either stress pattern (Experiment 3) while they were found to discriminate between the two stress patterns (Experiment 4). Our findings are the first to demonstrate that the trochaic bias is acquired by 6 months of age, is language specific and can be predicted by the rhythmic properties of the language in acquisition. We discuss the implications of this very early acquisition for our understanding of the emergence of segmentation abilities. 相似文献

In a recent working paper, Chen (2008) argues that a methodology central to the cognitive dissonance literature (the free-choice paradigm) has suffered from an inability to separately measure how much choices affect people’s preferences, and how much they simply reflect those preferences, by failing to fully control for the fact that subjects tend to choose goods they prefer. Although Sagarin and Skowronski concede this, they discount Chen’s argument, claiming that for revealed preferences to completely account for observed choice-effects the relationship between choice and preference would have to be unrealistically high. In this comment, we argue that their critique both misses the crux of Chen’s analysis, and is incorrect. Specifically, to properly test whether choices affect preferences, it is essential that researchers experimentally control for revealed preferences rather than speculate how much of a role they may play. Moreover, Sagarin and Skowronski’s critique rests on two fundamental errors—a misunderstanding of the function of the null-hypothesis and a misunderstanding of preference-measurement psychometrics. These errors leads Sagarin and Skowronski to suggest alternative experimental designs which while a good first step, do not address the problems identified in Chen (2008). 相似文献

Up to now functional hemispheric asymmetries for global/local processing have mainly been investigated with hierarchical letters as stimuli. In the present study, three experiments were conducted to examine whether corresponding visual-field (VF) effects can also be obtained with more naturalistic stimuli. To this end, images of animals with a pattern placed on their body were displayed as stimuli. The task for the global level and for the local level was to categorize the animals and the patterns, respectively. As a result, VF-effects were also found for these stimuli and tasks. It is concluded that the hemispheric differences observed for hierarchical letters also hold for naturalistic stimuli. 相似文献

句子语境中语义联系效应和句法效应的研究 总被引:2,自引:1,他引:1
通过对比研究句子语境中句法成分和语义联系对目标词加工的不同影响,来探讨句子语境的作用机制和作用点问题。实验一采用词汇命名任务研究发现,句法违反对词汇命名会产生抑制作用,而语义违反对词汇命名却没有发现抑制作用。实验二利用词汇决定任务发现,句法和语义成分影响词汇决定任务,句法违反和语义违反对词汇决定任务均会产生抑制作用。结果表明,句子语境加工中,对内容词语义整合过程中存在一个句法成分的独立加工水平。 相似文献

Making a Party Leader Less of a Party Member: The Impact of Ambivalence on Assimilation and Contrast Effects in Political Party Attitudes 总被引:1,自引:0,他引:1
Geoffrey Haddock 《Political psychology》2003,24(4):769-780
The present study tested the degree to which attitudes about a political party would be influenced by the context in which the party leader was rendered cognitively accessible. A sample of British undergraduates evaluated Prime Minister Tony Blair before expressing their opinion about the Labour party. In one condition, the two items were structured such that Blair was expected to be included in participants' representation of the party. In a second condition, the same items were structured such that Blair was expected to be excluded from participants' representation of the party. The results supported the hypothesis that manipulating the context in which Blair was made salient would produce different effects on a subsequent judgment of the Labour party, but only among politically ambivalent respondents. 相似文献

Recent studies have documented a “third-person effect” whereby people are found to judge others as more influenced than themselves by the mass media. Meanwhile, contemporary research on issue framing has demonstrated the powerful role of mass media in shaping people's political judgments. But are the perceptual judgments that define third-person effects sensitive to how the media frame an issue? Two studies investigated this question in the context of the Lewinsky-Clinton scandal, one in late August 1998 and the other during spring 1999. Several hundred undergraduates in each study were randomly assigned to one of two media frames. In the 1998 study, the political scandal was depicted as a matter of sexual indiscretion by the president or as legal wrongdoing; in the 1999 study, the recently concluded impeachment process was depicted as the consequence of partisanship or of Clinton's actions. The participants’ judgments of media influence on themselves and on the public were then recorded. The results show that third-person effects were sensitive to issue framing, but change occurred primarily in participants’ judgments about their own vulnerability to media influence. 相似文献

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
