Using a priming procedure, 4 experiments were carried out to investigate the effects of a short preexposure of a prime that was a radical or contained radicals identical to the target. Significant facilitation was found when the target contained the prime as a radical, although only for low-frequency targets which did not arise merely as a result of graphical similarity. Facilitation also occurred when the prime and target shared a radical in the same position but not when in different positions. When the prime and target had exactly the same radicals but in different positions, however, the priming effect was inhibitory. This set of results suggests that simple characters (radicals) and complex characters are represented at a different level. 相似文献
This article aims to investigate the training effect of working memory in older adults. A total of 43 older adults ranging in age from 75 to 95 were recruited to participate in the study. A battery of tests regarding central executive function, working memory, and primary mental ability were administered in the pretest phase. A total of 22 of the older participants were randomly selected as the intervention group. Thirteen days after the pretest, the same tests were administered to all of the participants. The results showed that (1) the differences in the pretest and posttest gains in the task-switching tests were not significant between the intervention group and the control group; (2) the performance of the intervention group on the operation working memory span test and the graphical reasoning test showed a significant improvement after the intervention compared with the control group who did not receive the intervention. We can conclude that the working memory of old adults may be improved by an intervention targeting the central executive system. However, this possibility needs further investigation. 相似文献
It has become increasingly common for young children to be taken care of by multiple caregivers in China after the socio-economic reforms. Complex migration patterns and high female labour force participation have led to children receiving care from various individuals in different contexts. However, little is known about how childcare arrangements are associated with child health well-being. This study examines various early childhood caregivers and their influences on children’s physical health in China. Using data from the China Health and Nutrition Survey (CHNS 1991–2011) with 3,470 children aged 2 to 6, we first identified different types of childcare arrangements in and outside of the household based on who provides the care, where they provide the care, and the intensity of the care. Then we examined the relationship between various childcare arrangements and health outcomes for children. Overall, household members undertook early childhood care tasks in China, with an increase in grandparents as primary caregivers between 1991 and 2011. The proportion of children receiving formal childcare fluctuated around 20% during this period. The findings suggest that: 1) primary caregiver in the household other than parents is not associated with undesirable physical health outcomes; 2) formal childcare outside the household is associated with higher height and lower BMI scores; 3) primary caregivers in the household, particular grandparents, moderate the association between childcare arrangements outside the household and children’s health outcomes. It yields an implication that early childhood care policies incorporating multiple caregivers would benefit children’s well-being in China.

The current research tested the concept of institutional agency (IA) and its implications for laypeople's attribution patterns related to economic behaviors and organizational responsibilities. The term “institutional agency” refers to a set of lay theories about whether or not an organization can have personhood and related mental properties, such as wishes, desires, intents, and responsibility. Through three cross‐cultural studies, we found that people do form certain beliefs about IA which are similar to the legal discourse of institutional responsibility. However, there are significant cultural differences in views of IA, and the concept is more mentally salient for Americans than for Chinese. In Study 1, we distinguished institutional from group agency by showing the cultural differences on attributions in the scenario with “individual vs. group agency” and the scenario with “individual vs. institutional agency.” In Study 2, we again demonstrated the stronger salience of IA for Americans than for Chinese by including the individual, group, and institutional agencies together in one scenario. In Study 3, we further demonstrated that the concept of IA is more salient for Americans by presenting three different agents in separate scenarios. The practical implications of these cultural differences for cross‐cultural understanding and the psychological effects of economic globalization are discussed. 相似文献
