How do children acquire exact meanings for number words like three or forty‐seven? In recent years, a lively debate has probed the cognitive systems that support learning, with some arguing that an evolutionarily ancient “approximate number system” drives early number word meanings, and others arguing that learning is supported chiefly by representations of small sets of discrete individuals. This debate has centered around the findings generated by Wynn's ( 1990 , 1992 ) Give‐a‐Number task, which she used to categorize children into discrete “knower level” stages. Early reports confirmed Wynn's analysis, and took these stages to support the “small sets” hypothesis. However, more recent studies have disputed this analysis, and have argued that Give‐a‐Number data reveal a strong role for approximate number representations. In the present study, we use previously collected Give‐a‐Number data to replicate the analyses of these past studies, and to show that differences between past studies are due to assumptions made in analyses, rather than to differences in data themselves. We also show how Give‐a‐Number data violate the assumptions of parametric tests used in past studies. Based on simple non‐parametric tests and model simulations, we conclude that (a) before children learn exact meanings for words like one, two, three, and four, they first acquire noisy preliminary meanings for these words, (b) there is no reliable evidence of preliminary meanings for larger meanings, and (c) Give‐a‐Number cannot be used to readily identify signatures of the approximate number system. 相似文献
This study examines how consumers' corporate social responsibility (CSR)‐related activities in social media affect their responses to brands. We defined consumers' CSR‐related activities in social media as the extent to which consumers use social media to engage in CSR communication by companies. An online survey was conducted to examine social media users in China, the largest consumer market in today's global economies. This study developed a theoretical model and empirically tested the relationships between consumers' CSR‐related activities in social media, identification with the brand, and three consumer behavior outcomes: electronic word‐of‐mouth (eWOM) intention, brand attitude, and purchase intention. The results suggested that consumers' CSR‐related activities in social media significantly impacted eWOM intention and purchase intention through enhancing identification with the brand and positive brand attitude. This study provides important insights on consumer behavior and CSR by investigating social media, an important and emerging marketing platform. Moreover, this study fills in the research gap about the association between consumers' CSR‐related activities in social media and their responses to brands. Theoretical and managerial implications for CSR strategies in social media are discussed. 相似文献
Phonotactic probability, neighborhood density, and onset density were manipulated in 4 picture-naming tasks. Experiment 1 showed that pictures of words with high phonotactic probability were named more quickly than pictures of words with low phonotactic probability. This effect was consistent over multiple presentations of the pictures (Experiment 2). Manipulations of phonotactic probability and neighborhood density showed only an influence of phonotactic probability (Experiment 3). In Experiment 4, pictures of words with sparse onsets were named more quickly than pictures of words with dense onsets. The results of these experiments provide additional constraints on the architecture and processes involved in models of speech production, as well as constraints on the connections between the recognition and production systems. 相似文献

The present pioneering study investigated the differences across various types of family structure among Chinese adolescents with proactive and reactive aggression. It aimed at providing frontline social workers and family therapists with inspirations for designing suitable interventions for adolescents with specific subtypes of aggressive behavior from different family structure backgrounds. After completing an online survey including the Reactive and Proactive Aggression Questionnaire (RPQ) and the subscales of the Child Behavior Checklist – Youth Self-report (CBCL-YSR) on aggressive behavior, delinquent behavior, and anxious/depressed symptom, 520 out of 13,338 Chinese adolescents aged 11 to 18 were randomly selected and stratified based on the types of family structure (intact family, single father family, single mother family, stepfather family, and stepmother family). Expectedly, boys elicited more proactive aggression, delinquent behaviors, and aggressive behaviors than girls. Besides, significant cross-structural differences were found between children from stepmother family, who showed more proactive aggression, anxious/depressed symptoms, aggressive behaviors, and delinquent behaviors, and those from intact family regardless of gender. The interaction effects between gender and family structure were significant for reactive aggression, anxious/depressed behavior, and aggressive behavior. An interaction effect showed boys from stepmother families were more reactively aggressive than those from intact families. In addition, more anxious/depressed symptoms were found in boys from stepmother family than those from intact and single mother families. In conclusion, the impacts of family structure on proactive aggression and delinquent behavior are not gender specific, but the impacts on reactive aggression and anxious/depressed behavior are only specific to boys.
Children's understanding of the quantities represented by number words (i.e., cardinality) is a surprisingly protracted but foundational step in their learning of formal mathematics. The development of cardinal knowledge is related to one or two core, inherent systems – the approximate number system (ANS) and the object tracking system (OTS) – but whether these systems act alone, in concert, or antagonistically is debated. Longitudinal assessments of 198 preschool children on OTS, ANS, and cardinality tasks enabled testing of two single‐mechanism (ANS‐only and OTS‐only) and two dual‐mechanism models, controlling for intelligence, executive functions, preliteracy skills, and demographic factors. Measures of both OTS and ANS predicted cardinal knowledge in concert early in the school year, inconsistent with single‐mechanism models. The ANS but not the OTS predicted cardinal knowledge later in the school year as well the acquisition of the cardinal principle, a critical shift in cardinal understanding. The results support a Merge model, whereby both systems initially contribute to children's early mapping of number words to cardinal value, but the role of the OTS diminishes over time while that of the ANS continues to support cardinal knowledge as children come to understand the counting principles. 相似文献
In the present study, we tested a serial mindfulness facets‐trait emotional intelligence (TEI)‐emotional distress‐multiple health behaviors mediation model in a sample of N =427 German‐speaking occupational therapists. The mindfulness facets‐TEI‐emotional distress section of the mediation model revealed partial mediation for the mindfulness facets Act with awareness (Act/Aware) and Accept without judgment (Accept); inconsistent mediation was found for the Describe facet. The serial two‐mediator model included three mediational pathways that may link each of the four mindfulness facets with multiple health behaviors. Eight out of 12 indirect effects reached significance and fully mediated the links between Act/Aware and Describe to multiple health behaviors; partial mediation was found for Accept. The mindfulness facet Observe was most relevant for multiple health behaviors, but its relation was not amenable to mediation. Implications of the findings will be discussed. 相似文献
