Previous research showed that handwriting production is mediated by linguistically oriented processing units such as syllables and graphemes. The goal of this study was to investigate whether French adults also activate another kind of unit that is more related to semantics than phonology, namely morphemes. Experiment 1 revealed that letter duration and inter-letter intervals were longer for suffixed words than for pseudo-suffixed words. These results suggest that the handwriting production system chunks the letter components of the root and suffix into morpheme-sized units. Experiment 2 compared the production of prefixed and pseudo-prefixed words. The results did not yield significant differences. This asymmetry between suffix and prefix processing has also been observed in other linguistic tasks. In suffixed words, the suffix would be processed on-line during the production of the root, in an analytic fashion. Prefixed words, in contrast, seem to be processed without decomposition, as pseudo-affixed words. 相似文献

This paper investigates whether culture can be used to segment a market. Using Indians, resident in Britain (British Indians) as an example, previous research suggests that culture's manifestation within buyer behaviour provides sufficient evidence to justify its use as a market segment variable. Using brown goods (television sets, video equipment, music systems etc) a comparative quantitative study examined the impact of a range of cultural values upon the buying behaviour of British Indians and British Caucasians, to identify significant differences between the two. Although a significant difference was found, the amount of similarity between the two sample groups suggests culture should not be used as a segmentation variable. This research has implications for organisations seeking to develop ethnic minority orientated marketing strategies. Copyright © 2003 Henry Stewart Publications. 相似文献

本研究将"童年创伤"定义为"个体14岁以前所经历的,站在主体的角度主观感受到的创伤性事件"。采用问卷调查法对302名大学生进行调查,通过定量加定性的方式探索了童年创伤与抑郁之间的关系。相关分析表明:主观童年创伤症状、外向性、抗挫折能力、抑郁之间两两显著相关;结构方程模型表明:主观童年创伤症状通过外向性、抗挫折能力完全、多重中介作用间接预测抑郁。本研究结果在理论和实践层面对大学生抑郁问题的预防和干预工作提供重要的借鉴依据。 相似文献

The present research investigated how different dimensions of narcissism (i.e., assertive, antagonistic, and vulnerable) and content-specific forms of assertive narcissism (i.e., intellectual ability, physical attractiveness, social dominance) are related to overclaiming bias (i.e., the tendency to illegitimately claim knowledge). In the data from a large-scale online study (N = 1,658), the associations between overclaiming bias and any kind of narcissism were smaller than in many previous studies. Furthermore, assertive narcissism was more positively related to overclaiming bias than antagonistic and vulnerable narcissism were. Intellectual-ability-specific and social-dominance-specific assertive narcissism were more positively related to overclaiming bias than physical-attractiveness-specific assertive narcissism was. Finally, multiple regression analyses suggested that the narcissism-overclaiming link is most robust for social-dominance-specific assertive narcissism. 相似文献

时距认知分段性指不同长度时距加工机制和表征方式不同。以往研究对1s范围时距认知分段性仍存在分歧,为此在规避以往研究局限基础上设计实验1和实验2。实验1和实验2分别采用双任务范式探讨心算任务对100ms和1000ms听、视时距比较的选择性干扰,结果表明,心算任务影响了1000ms听、视时距比较的75%差别阈限,心算加工负荷越大,75%差别阈限越大,但对100ms听、视时距比较的75%差别阈限没有影响。两项实验支持了1s范围视、听时距认知均具有分段性。 相似文献

Are Words Easier to Learn From Infant‐ Than Adult‐Directed Speech? A Quantitative Corpus‐Based Investigation 下载免费PDF全文

We investigate whether infant‐directed speech (IDS) could facilitate word form learning when compared to adult‐directed speech (ADS). To study this, we examine the distribution of word forms at two levels, acoustic and phonological, using a large database of spontaneous speech in Japanese. At the acoustic level we show that, as has been documented before for phonemes, the realizations of words are more variable and less discriminable in IDS than in ADS. At the phonological level, we find an effect in the opposite direction: The IDS lexicon contains more distinctive words (such as onomatopoeias) than the ADS counterpart. Combining the acoustic and phonological metrics together in a global discriminability score reveals that the bigger separation of lexical categories in the phonological space does not compensate for the opposite effect observed at the acoustic level. As a result, IDS word forms are still globally less discriminable than ADS word forms, even though the effect is numerically small. We discuss the implication of these findings for the view that the functional role of IDS is to improve language learnability. 相似文献

The ability to perform movement imagery has been shown to influence motor performance and learning in sports and rehabilitation. Self-report questionnaires have been developed to assess movement imagery ability in adults, such as the Movement Imagery Questionnaire 3 (MIQ-3); however, there is a dearth of developmentally appropriate measures for use with children. To address this gap, the focus of this research was to develop an imagery ability questionnaire for children. This process involved adaptation of the MIQ-3 via: i) cognitive interviewing with twenty children, ii) validation with 206 children by examining its factor structure via multitrait-multi method confirmatory factor analysis, and iii) examination of test-retest reliability with 23 children. The findings of Study 1 led to changes to the wording of the questionnaire and modifications of the instructions to successfully adapt the MIQ-3 for children aged 7–12 years. The validation undertaken in Study 2 found that a correlated-traits correlated-uniqueness model provided the best fit to the data. Finally, test-retest reliabilities varied from fair (for external visual imagery) to substantial (for kinesthetic imagery). With respect to ease of imaging, no significant gender or age-group differences were noted. However, significant difference were found among the three imagery modalities (p < .001), with external visual imagery rated as easiest to image and kinesthetic imagery rated as the most difficult. Taken together, findings support the use of the MIQ-C for examining movement imagery ability with children. 相似文献

We investigated the effects of linguistic experience and language familiarity on the perception of audio-visual (A-V) synchrony in fluent speech. In Experiment 1, we tested a group of monolingual Spanish- and Catalan-learning 8-month-old infants to a video clip of a person speaking Spanish. Following habituation to the audiovisually synchronous video, infants saw and heard desynchronized clips of the same video where the audio stream now preceded the video stream by 366, 500, or 666 ms. In Experiment 2, monolingual Catalan and Spanish infants were tested with a video clip of a person speaking English. Results indicated that in both experiments, infants detected a 666 and a 500 ms asynchrony. That is, their responsiveness to A-V synchrony was the same regardless of their specific linguistic experience or familiarity with the tested language. Compared to previous results from infant studies with isolated audiovisual syllables, these results show that infants are more sensitive to A-V temporal relations inherent in fluent speech. Furthermore, the absence of a language familiarity effect on the detection of A-V speech asynchrony at eight months of age is consistent with the broad perceptual tuning usually observed in infant response to linguistic input at this age. 相似文献
