潮汕话-普通话双言者的词汇习得年龄效应

采用潮汕话-普通话双言者为被试, 通过3个实验, 考察了词汇习得年龄效应。实验1采用汉字命名和图片命名范式, 证实了在双言者的两种语言中都存在词汇习得年龄效应。实验2和实验3分别采用语义范畴判断及声母监控任务, 在语义层面及语音层面检验了双言者的两种语言的词汇习得年龄效应的特点。结果表明, 在语义任务上发现了词汇习得年龄效应, 在语音任务上未发现。整个研究表明, 语义在汉语词汇习得年龄效应产生中具有重要作用, 支持了语义假设。     

Different attitudes toward humor between Chinese and American students: evidence from the Implicit Association Test

Although cross-cultural research indicates that Chinese people demonstrate less humor than do Americans, little research addresses the reasons. This cross-cultural difference may be largely due to different implicit attitudes toward humor held by Chinese and Americans, deeply rooted in the two cultural traditions. Both self-report evaluation and the Implicit Association Test (IAT) were used to compare Chinese and American attitudes toward humor. Although 60 Chinese undergraduate students showed no significant difference from 33 American exchange students in explicit attitudes toward humor, the former associated humor more frequently with unpleasant adjectives and seriousness with pleasant adjectives on the IAT; the opposite pattern was found for the American group. This indicated a negative implicit attitude toward humor among the Chinese students.     

当下高等医学人文教育的困境与出路

医学人文教育是医学教育不可或缺的重要组成部分,医学科学精神与医学人文精神的融合是医学学科发展的目标和方向.当下医学人文教育的困境在于:医学人文教育与政治教育混谈,人文教育目标不明;医学人文教学与社会现实脱节,人文教学效果不佳.破解医学人文教育的困境,必须从顶层设计,跳出医学人文教育看教育,实施医学人文教育发展战略,实现医学教育的全面、协调、可持续发展.

Cognitive obstacles against organ donation: The influence of negative attitudes,norms, and traditional beliefs on Chinese people's intention to donate organs after death

In China, the organ supply is severely insufficient to cover all people on the waiting list for donated organs, and numerous patients die awaiting transplant. To achieve a better understanding of cadaveric organ donation in Chinese culture, this study examined 300 Chinese adults, in both Fujian Province and Macao, regarding attitudes towards organ donation, subjective norms about organ donation and traditional beliefs about the body and death, examining the influences of these factors on respondents' donation intentions. Multiple hierarchical regression results suggest that more negative attitudes, unfavourable norms and traditional beliefs lead to lower donation intentions.

Type-based associations in grapheme-color synaesthesia revealed by response time distribution analyses

Determining the nature of binding in grapheme-color synaesthesia has consequences for understanding the neural basis of synaesthesia and visual awareness in general. We evaluated type- and token-based letter-color binding using a synaesthetic version of the object-reviewing paradigm. Although mean response times failed to reveal any significant differences between synaesthetes and control participants, RT analyses with ex-Gaussian distributions revealed that the response facilitation in the synaesthesia group reflected type representations exclusively, while response facilitation in the control group, who learned letter-color associations, was dominated by token representations. Thus, letter-color associations in associator synaesthetes are type-based, and do not involve binding to object tokens, consistent with their subjective reports. Contrary to recent studies that failed to find differences between synaesthetes and non-synaesthetes with behavioral measures, response time distribution analyses indicate that color sensations in synaesthetes are not simply the extreme form of normal letter-color associations, and cannot be attributed to demand characteristics.     

Acceptability of Behavioral Family Therapy among Caregivers in China

In the U.S., helping the noncompliant child and parent child interaction therapy represent behavioral family therapy programs that are empirically supported for treating the conduct problems of 2- to 7-year old children. This study examined how caregivers in China would view behavioral family therapy. Caregivers in Hangzhou, China reported the perceived age of deviance for behavioral family therapy targets (e.g., noncompliance) and rated the acceptability of behavioral treatment components (e.g., timeout). Chinese caregivers agreed with European-American culture on considering noncompliance, aggression, tantrums, and negative talk deviant during the pre-school period. Overall, Chinese caregivers considered all the following nine behavioral family therapy components acceptable: contingent praise, responsive play, ignoring deviant attention seeking, authoritative instruction-giving, warnings, chair timeouts, ignoring tantrums during timeout, room backups for chair timeouts, and immediate timeouts for aggression. However, specific parental reservations were found regarding backup procedures for chair timeouts, particularly room backups. Possible treatment accommodations of behavioral family therapy for Chinese families are discussed.     

The role of color information on object recognition: a review and meta-analysis

In this study, we systematically review the scientific literature on the effect of color on object recognition. Thirty-five independent experiments, comprising 1535 participants, were included in a meta-analysis. We found a moderate effect of color on object recognition (d = 0.28). Specific effects of moderator variables were analyzed and we found that color diagnosticity is the factor with the greatest moderator effect on the influence of color in object recognition; studies using color diagnostic objects showed a significant color effect (d = 0.43), whereas a marginal color effect was found in studies that used non-color diagnostic objects (d = 0.18). The present study did not permit the drawing of specific conclusions about the moderator effect of the object recognition task; while the meta-analytic review showed that color information improves object recognition mainly in studies using naming tasks (d = 0.36), the literature review revealed a large body of evidence showing positive effects of color information on object recognition in studies using a large variety of visual recognition tasks. We also found that color is important for the ability to recognize artifacts and natural objects, to recognize objects presented as types (line-drawings) or as tokens (photographs), and to recognize objects that are presented without surface details, such as texture or shadow. Taken together, the results of the meta-analysis strongly support the contention that color plays a role in object recognition. This suggests that the role of color should be taken into account in models of visual object recognition.     

Bayesian analogy with relational transformations

How can humans acquire relational representations that enable analogical inference and other forms of high-level reasoning? Using comparative relations as a model domain, we explore the possibility that bottom-up learning mechanisms applied to objects coded as feature vectors can yield representations of relations sufficient to solve analogy problems. We introduce Bayesian analogy with relational transformations (BART) and apply the model to the task of learning first-order comparative relations (e.g., larger, smaller, fiercer, meeker) from a set of animal pairs. Inputs are coded by vectors of continuous-valued features, based either on human magnitude ratings, normed feature ratings (De Deyne et al., 2008), or outputs of the topics model (Griffiths, Steyvers, & Tenenbaum, 2007). Bootstrapping from empirical priors, the model is able to induce first-order relations represented as probabilistic weight distributions, even when given positive examples only. These learned representations allow classification of novel instantiations of the relations and yield a symbolic distance effect of the sort obtained with both humans and other primates. BART then transforms its learned weight distributions by importance-guided mapping, thereby placing distinct dimensions into correspondence. These transformed representations allow BART to reliably solve 4-term analogies (e.g., larger:smaller::fiercer:meeker), a type of reasoning that is arguably specific to humans. Our results provide a proof-of-concept that structured analogies can be solved with representations induced from unstructured feature vectors by mechanisms that operate in a largely bottom-up fashion. We discuss potential implications for algorithmic and neural models of relational thinking, as well as for the evolution of abstract thought.
