In this 8‐year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty‐four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over 8 years. Between the ages of 4 to 10 years, they were administered tasks of vocabulary and related cognitive skills. At age 11, comprehensive reading skills, including character recognition, reading fluency, and reading comprehension were examined. Individual differences in vocabulary developmental profiles were estimated using the intercept‐slope cluster method. Vocabulary development was then examined in relation to later reading outcomes. Three subgroups of lexical growth were classified, namely high‐high (with a large initial vocabulary size and a fast growth rate), low‐high (with a small initial vocabulary size and a fast growth rate) and low‐low (with a small initial vocabulary size and a slow growth rate) groups. Low‐high and low‐low groups were distinguishable mostly through phonological skills, morphological skills and other reading‐related cognitive skills. Childhood vocabulary development (using intercept and slope) explained subsequent reading skills. Findings suggest that language‐related and reading‐related cognitive skills differ among groups with different developmental trajectories of vocabulary, and the initial size and growth rate of vocabulary may be two predictors for later reading development.  相似文献

The authors address the effects of money gain and loss on individually perceived value as predicted by prospect theory in a time gain‐and‐loss context. Three experiments were conducted. Experiment 1 results support the prospect theory concept of value function. According to Experiment 2 results, the amount of money involved exerted different impacts on individual perceptions—specifically, study participants preferred gaining $1 on one occasion to gaining 50 cents over two occasions and preferred losing $1 one time to losing 50 cents twice. Further, the combined results indicate that the study participants held different perceptions of the value of “short time” versus “little money”—that is, they preferred saving an extra 2 minutes on one occasion to saving 1 minute on two occasions and preferred waiting an extra 1 minute two times to waiting an extra 2 minutes one time.

This research investigates the effects of affect and cognition in consumers' information processing of branded content on Facebook pages. A model was suggested to delve into the elaboration process leading to consumer attitude formation. A 2 (purchase‐decision involvement: low versus high) × 2 (product categories: hedonic versus utilitarian) × 2 (sources of Facebook posts: brand posts versus consumer posts) between‐subjects experiment was conducted online. The validated model demonstrates the main effects that affective elaboration significantly supersedes cognitive elaboration in forming attitudes toward the posts and attitudes toward the brand. Post hoc analyses show further evidence of the interaction effects that affective elaboration is the dominant influencer when consumers process brand‐related information in Facebook posts across situations. Theoretical implications for future research and managerial suggestions for social media marketing are discussed. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Creaturely life is finite life. Transhumanism suggests that human life will be better and even fulfilled in a new way, if humans can overcome some of the finite conditions now given. I argue that there are theological, ethical, and biological points to be taken into consideration that may challenge the transhuman vision of a good life. The finite conditions of human life are what makes human life human, and these conditions are also part of why the deeper meaning of human life is realized in love for others, and not in the quest for making one's own life go on (almost) endlessly. In addition to looking at some material from popular culture and the philosopher Hans Jonas, the article also draws on recent discussions on transhumanism present in contemporary theology.  相似文献

Using longitudinal data collected at four time points from 191 dyads of Mexican‐origin adolescent first‐time mothers and their mother figures, we examined changes in and socialization of traditional gender role attitudes across the transition to parenthood using latent growth curve modeling and actor – partner interdependence modeling. Longitudinal growth models indicated that, regardless of nativity status, adolescent mothers' and their foreign‐born mother figures' gender role attitudes became more egalitarian across adolescents' transition to parenthood, spanning from the 3rd trimester of pregnancy to 36 months postpartum. Furthermore, actor‐partner interdependence modeling suggested that adolescents' and their mother figures' gender role attitudes during adolescents' third trimester of pregnancy equally contributed to subsequent increases in one another's gender role attitudes at 10 months postpartum. Importantly, this reciprocal socialization process was not moderated by adolescent mothers' nor by their mother figures' nativity status. Findings suggest that it is important to understand the cultural and intergenerational family processes that contribute to the development of gender role attitudes during the transition to parenthood for adolescent mothers and their mother figures in Mexican‐origin families.  相似文献

Grooming behaviours are thought to be a crucial aspect of parenting and integral to the sociality of non‐human mammals, but there have been few empirical studies on how grooming might be relevant to parenting and socialization processes in humans. Study 1 is a quantitative cross‐cultural comparison of grooming practices in two cultural settings: an urban centre in Burma (Myanmar) and an urban centre in the United States. The study uses naturalistic video data of 57 families to analyse grooming behaviours directed at children. A broad range of ages was sampled in each culture to examine the developmental trajectory of grooming behaviours. Results indicate that significant cultural differences exist between Burma and the United States, with Burmese children being groomed by their caregivers more often than U.S. children. Results also indicate that cultural differences in grooming practices begin early and remain constant across age. An unexpected finding was that Burmese families were more variable in their behaviour than U.S. families. Study 2 attempts to explain this variability by using ethnography to describe how sociodemographic changes in Burma are leading to changes in parental values and socialization practices in the schools, but how embodied primary care in the homes appear resistant to change.  相似文献

This study explores the relationship between emotional intelligence (EI) and health‐related quality of life (HRQoL) in a sample of Spanish older adults who are institutionalised in long‐term care (LTC) facilities. One hundred fifteen institutionalised individuals (47.82% women; 88.3 ± 7.9 years) from southern Spain completed a set of questionnaires that included measures of EI, health and personality. Data were analysed via hierarchical regression. After controlling for personality and sociodemographic variables, the EI dimensions, emotional comprehension and emotional facilitation, accounted for part of the variance in several HRQoL facets. These dimensions could have an important role in the HRQoL of residents in LTC. Moreover, the use of a performance measure addresses the limitations of previous studies that have relied on self‐report measures. These aspects underscore the importance of the results of this study.  相似文献
