网站临场感能否增强女性购买意愿?

为了克服网络虚拟性的影响,网络商铺往往通过提升网站临场感以弥补购物体验不足的问题。那么,网站临场感是否会对女性消费者这一细分群体产生影响呢?本研究从网站临场感的视角出发,以女大学生为研究对象、服装网站为实验材料,采用实验法研究了网站临场感对女性网络购买意愿的影响及其发生机制。研究发现:网站临场感对女性网络购买意愿具有显著的正向影响;网站临场感可以通过风险感知和沉醉感的中介作用对女性网络购买意愿产生影响,且该中介作用包含了三条路径,即风险感知的中介作用、沉醉感的中介作用以及风险感知和沉醉感的链式中介作用。

Parental Involvement in Primary School Education: its Relationship with Children’s Academic Performance and Psychosocial Competence through Engaging Children with School

The benefits of parental involvement in children’s education have been well established but increasing evidence suggests that overparenting may have adverse effects on children. The question of whether excessive parental involvement hinders children’s academic and psychosocial development warrants further investigations. This study examined the associations of parental educational involvement at home and in school with academic performance and psychological health of 507 Chinese Grade 3 schoolchildren in Hong Kong. Parents reported on their level of involvement in children’s schooling and their children’s psychosocial issues. Children were surveyed to determine their school engagement, and their Chinese language and mathematics attainment was assessed. We also explored the underlying mechanism by testing children’s engagement with school as a mediator of the relationships. Our results showed that home-based parental educational involvement was positively associated with children’s language competence and psychosocial wellbeing, and the associations were linked through engaging children with school. However, the benefits reached a plateau at higher level of parental involvement in children’s learning at home. School-based parental involvement had an indirect effect on children’s prosocial behavior through school engagement. These findings highlight the significance of optimal level of parental involvement in children’s education at home for children’s development.

个体对效价预期和风险评估的时程加工机制:来自ERP的证据

采用事件相关电位技术(ERP),通过简单赌博任务,操纵结果预期的效价(输或赢)与风险(高风险与低风险),考察了个体对结果预期阶段的效价和风险评估的脑内时程动态加工过程。脑电结果发现:(1)在N2成分上,结果预期的效价主效应显著,预期输比预期赢能够引起更大的N2波幅;结果预期的风险主效应不显著。(2)在N500成分上,效价与风险之间的交互作用边缘显著,进一步简单效应分析发现,在预期输的条件下,肯定会输的N500波幅显著大于可能会输;而在预期赢的条件下,肯定会赢与可能会赢之间的N500波幅差异不显著。这说明,在不确定决策过程中的结果预期阶段,个体可能先对结果预期的效价进行加工,然后再对风险进行评估。     

Life as a Pregnant Genetic Counselor: Take Two

Pregnancy is not always an expected or happy event. When a woman is facing an unplanned pregnancy, it can be a very difficult emotional experience. As with any pregnancy, working in a prenatal setting can impact how a woman feels about and handles her pregnancy. Once again, one genetic counselor discusses her experiences, this time during a second, unplanned pregnancy.     

Eye movements of second language learners when reading spaced and unspaced Chinese text

The effect of spacing in relation to word segmentation was examined for four groups of non-native Chinese speakers (American, Korean, Japanese, and Thai) who were learning Chinese as second language. Chinese sentences with four types of spacing information were used: unspaced text, word-spaced text, character-spaced text, and nonword-spaced text. Also, participants' native languages were different in terms of their basic characteristics: English and Korean are spaced, whereas the other two are unspaced; Japanese is character based whereas the other three are alphabetic. Thus, we assessed whether any spacing effects were modulated by native language characteristics. Eye movement measures showed least disruption to reading for word-spaced text and longer reading times for unspaced than character-spaced text, with nonword-spaced text yielding the most disruption. These effects were uninfluenced by native language (though reading times differed between groups as a result of Chinese reading experience). Demarcation of word boundaries through spacing reduces non-native readers' uncertainty about the characters that constitute a word, thereby speeding lexical identification, and in turn, reading. More generally, the results indicate that words have psychological reality for those who are learning to read Chinese as a second language, and that segmentation of text into words is more beneficial to successful comprehension than is separating individual Chinese characters with spaces.     

Non-target language processing in Chinese-English bilinguals: a study of event-related potential

The event-related brain potential (ERP) technique was used to investigate the neural mechanism of non-target language processing in Chinese-English bilinguals. Participants were presented with a mixed list of Chinese and English words and required to make conceptual decisions for words in one language and ignore words in the other non-target language. Regardless of whether the nontarget word was in Chinese or English, the ERPs they elicited were modulated by word frequency, suggesting that their meaning had been accessed. The N400 peak was delayed in the English as the non-target language condition, probably because participants were less proficient in English. The results suggest that the non-target language can be processed during conceptual tasks with participants' proficiency in this language being a critical factor.     

Return Migrant or Diaspora: An Exploratory Study of New-Generation Chinese–Canadian Youth Working in Hong Kong

The circular movement of migrants between their homelands and adopted countries has problematized the previous linear understanding of return migration. However, the concept of circular migration tends to apply to migrants whose movement is enabled by their extensive pre-migration connections with their homelands. In this paper, we report findings of a study on a group of new-generation Chinese–Canadian youth working in Hong Kong. Although, like many return migrants, this group of young people had economic reasons for moving to Hong Kong (their parents' homeland), they do not position themselves as return migrants. Instead, they have kept a strong Canadian identity by maintaining unique friendship circles and perceiving Canada as a home to which they will one day return. We highlight in this paper some implications of their experiences for transnational migration studies.
