Generic sentences (e.g., "Birds lay eggs") convey generalizations about entire categories and may thus be an important source of knowledge for children. However, these sentences cannot be identified by a simple rule, requiring instead the integration of multiple cues. The present studies focused on 3- to 5-year-olds' (N = 91) use of morphosyntactic cues--in particular, on whether children can (a) interpret indefinite singular noun phrases (e.g., "a strawberry") as generic and (b) use a verb's tense and aspect (e.g., "A bat sleeps/slept/is sleeping upside down") to determine whether its subject noun phrase is generic. Children demonstrated sensitivity to both cues. Thus, solving the in-principle problem of identifying generics may not be beyond the reach of young children's comprehension skills. 相似文献

How do children reason about academic performance across development? A classic view suggests children’s intuitive theories in this domain undergo qualitative changes. According to this view, older children and adults consider both effort and skill as sources of performance (i.e., a “performance = effort + skill” theory), but younger children can only consider effort (i.e., a “performance = effort” theory). Results from two studies (N = 240 children aged 4–9) contradict the claim of theory change, suggesting instead that children as young as 4 operate with an intuitive theory of academic performance that incorporates both effort and skill as explanatory concepts. This work reveals that children’s understanding of academic performance is more continuous across development than previously assumed. 相似文献

These studies investigate how the distinction between generic sentences (e.g., "Boys are good at math") and nongeneric sentences (e.g., "Johnny is good at math") shapes children's social cognition. These sentence types are hypothesized to have different implications about the source and nature of the properties conveyed. Specifically, generics may be more likely to imply that the referred-to properties emerge naturally from an internal source, which may cause these properties to become essentialized. Four experiments (N = 269 four-year-olds and undergraduates) confirmed this hypothesis but also suggested that participants only essentialize the information provided in generic form when this construal is consistent with their prior theoretical knowledge. These studies further current understanding of language as a means of learning about others. 相似文献

A valuable extension of the single-rating regression discontinuity design (RDD) is a multiple-rating RDD (MRRDD). To date, four main methods have been used to estimate average treatment effects at the multiple treatment frontiers of an MRRDD: the “surface” method, the “frontier” method, the “binding-score” method, and the “fuzzy instrumental variables” method. This article uses a series of simulations to evaluate the relative performance of each of these four methods under a variety of different data-generating models. Focusing on a two-rating RDD (2RRDD), we compare the methods in terms of their bias, precision, and mean squared error when implemented as they most likely would be in practice—using optimal bandwidth selection. We also apply the lessons learned from the simulations to a real-world example that uses data from a study of an English learner reclassification policy. Overall, this article makes valuable contributions to the literature on MRRDDs in that it makes concrete recommendations for choosing among MRRDD estimation methods, for implementing any chosen method using local linear regression, and for providing accurate statistical inferences. 相似文献

Generic statements (e.g., “Lions have manes”) make claims about kinds (e.g., lions as a category) and, for adults, are distinct from quantificational statements (e.g., “Most lions have manes”), which make claims about how many individuals have a given property. This article examined whether young children also understand that generics do not depend purely on quantitative information. Five‐year‐olds (n = 36) evaluated pairs of questions expressing properties that were matched in prevalence but varied in whether adults accept them as generically true (e.g., “Do lions have manes?” [true] vs. “Are lions boys?” [false]). Results demonstrated that children evaluate generics based on more than just quantitative information. Data suggest that even young children recognize that generics make claims about kinds. 相似文献

Describing behaviors as reflecting categories (e.g., asking children to “be helpers”) has been found to increase pro-social behavior. The present studies (N = 139, ages 4–5) tested whether such effects backfire if children experience setbacks while performing category-relevant actions. In Study 1, children were asked either to “be helpers” or “to help,” and then pretended to complete a series of successful scenarios (e.g., pouring milk) and unsuccessful scenarios (e.g., spilling milk while trying to pour). After the unsuccessful trials, children asked to “be helpers” had more negative attitudes. In Study 2, asking children to “be helpers” impeded children's helping behavior after they experienced difficulties while trying to help. Implications for how category labels shape beliefs and behavior are discussed. 相似文献

Young Children's Self‐Concepts Include Representations of Abstract Traits and the Global Self 
下载免费PDF全文
下载免费PDF全文 There is debate about the abstractness of young children's self‐concepts—specifically, whether they include representations of (a) general traits and abilities and (b) the global self. Four studies (N = 176 children aged 4–7) suggested these representations are indeed part of early self‐concepts. Studies 1 and 2 reexamined prior evidence that young children cannot represent traits and abilities. The results suggested that children's seemingly immature judgments in previous studies were due to peculiarities of the task context not the inadequacy of children's self‐concepts. Similarly, Studies 3 and 4 revealed that, contrary to claims of immaturity in reasoning about the global self, young children update their global self‐evaluations in flexible, context‐sensitive ways. This evidence suggests continuity in the structure of self‐concepts across childhood. 相似文献

In a Registered Report, the authors propose a new survey-bias-mitigation method—incorporating inverse probability weighting via boosted regression—to better understand lesbian, gay, bisexual, or questioning (LGBQ)-heterosexual youth risk disparities. This method is tested using the 2019 US Centers for Disease Control and Prevention-collected Youth Risk Behavior Survey (YRBS) national data, which contain 12,847 observations (ages 12–18 [M = 16, SD = 1.25]; 49.1% male [8.7% LGBQ] and 50.9% female [22.4% LGBQ]; nationally representative regarding race and ethnicity). Looking across 44 outcomes, the authors found that the YRBS contains responses that are potentially biased against LGBQ youth in systematic ways, inflating perceived risk for this group in some outcomes. This potential bias is more pronounced among reported males than among reported females, and it is more pronounced for low-incidence outcomes. For example, the steroid-use disparity estimate among reported males reduced by 67%, while the reduction in bullying victimization was small and not statistically significant. The authors discuss robustness of results, the new method, and data policy implications. 相似文献

When do adolescents' dreams of promising journeys through high school translate into academic success? This monograph reports the results of a collaborative effort among sociologists and psychologists to systematically examine the role of schools and classrooms in disrupting or facilitating the link between adolescents' expectations for success in math and their subsequent progress in the early high school math curriculum. Our primary focus was on gendered patterns of socioeconomic inequality in math and how they are tethered to the school's peer culture and to students' perceptions of gender stereotyping in the classroom. To do this, this monograph advances Mindset × Context Theory. This orients research on educational equity to the reciprocal influence between students' psychological motivations and their school-based opportunities to enact those motivations. Mindset × Context Theory predicts that a student's mindset will be more strongly linked to developmental outcomes among groups of students who are at risk for poor outcomes, but only in a school or classroom context where there is sufficient need and support for the mindset. Our application of this theory centers on expectations for success in high school math as a foundational belief for students' math progress early in high school. We examine how this mindset varies across interpersonal and cultural dynamics in schools and classrooms. Following this perspective, we ask:
- 1. Which gender and socioeconomic identity groups showed the weakest or strongest links between expectations for success in math and progress through the math curriculum?
- 2. How did the school's peer culture shape the links between student expectations for success in math and math progress across gender and socioeconomic identity groups?
- 3. How did perceptions of classroom gender stereotyping shape the links between student expectations for success in math and math progress across gender and socioeconomic identity groups?
