Although math anxiety is associated with poor mathematical knowledge and low course grades (Ashcraft & Krause, 2007), research establishing a connection between math anxiety and math achievement has generally been conducted with young adults, ignoring the emergence of math anxiety in young children. In the current study, we explored whether math anxiety relates to young children's math achievement. One hundred and fifty-four first- and second-grade children (69 boys, 85 girls) were given a measure of math achievement and working memory (WM). Several days later, children's math anxiety was assessed using a newly developed scale. Paralleling work with adults (Beilock, 2008), we found a negative relation between math anxiety and math achievement for children who were higher but not lower in WM. High-WM individuals tend to rely on WM-intensive solution strategies, and these strategies are likely disrupted when WM capacity is co-opted by math anxiety. We argue that early identification and treatment of math anxieties is important because these early anxieties may snowball and eventually lead students with the highest potential (i.e., those with higher WM) to avoid math courses and math-related career choices. 相似文献

Generic statements about the abilities of children's social groups (e.g. ‘Girls/Boys are good at this game’) negatively impact children's performance – even if the statements are favorable towards children's own social groups. We explored the mechanism by which generic language impairs children's performance. Across three studies, our findings suggest that generic statements influence children's performance by creating an entity belief (i.e. a belief that a fixed ability determines performance). Children who were exposed to a generic statement about their social group's ability performed worse than children in control conditions. This effect hurt children's performance even when the person who made the generic statement was no longer present and a new person not privy to the statement replaced them. However, when children heard a generic statement paired with an effort explanation (i.e. ‘Girls/Boys are good at this game because they try really hard when they draw’) they performed better than children who heard the generic statement with no explanation (i.e. just ‘Girls/Boys are good at this game’) and children who heard the generic statement paired with a trait explanation (i.e. ‘Girls/Boys are good at this game because they are smart and really good at drawing’). This work uncovers when and how generic statements that refer to the ability of one's social group hinder performance, informing the development of practices to improve student motivation and learning. 相似文献

Privacy is psychologically important, vital for democracy, and in the era of ubiquitous and mobile surveillance technology, facing increasingly complex threats and challenges. Yet surveillance is often justified under a trope that one has ‘nothing to hide’. We conducted focus groups (N = 42) on topics of surveillance and privacy and using discursive analysis, identify the ideological assumptions and the positions that people adopt to make sense of their participation in a surveillance society. We find a premise that surveillance is increasingly inescapable, but this was only objected to when people reported feeling misrepresented, or where they had an inability to withhold aspects of their identities. The (in)visibility of the surveillance technology also complicated how surveillance is constructed. Those interested in engaging the public in debates about surveillance may be better served by highlighting the identity consequences of surveillance, rather than constructing surveillance as a generalised privacy threat. 相似文献

Children with pre‐ or perinatal brain injury (PL) exhibit marked plasticity for language learning. Previous work has focused mostly on the emergence of earlier‐developing skills, such as vocabulary and syntax. Here we ask whether this plasticity for earlier‐developing aspects of language extends to more complex, later‐developing language functions by examining the narrative production of children with PL. Using an elicitation technique that involves asking children to create stories de novo in response to a story stem, we collected narratives from 11 children with PL and 20 typically developing (TD) children. Narratives were analysed for length, diversity of the vocabulary used, use of complex syntax, complexity of the macro‐level narrative structure and use of narrative evaluation. Children’s language performance on vocabulary and syntax tasks outside the narrative context was also measured. Findings show that children with PL produced shorter stories, used less diverse vocabulary, produced structurally less complex stories at the macro‐level, and made fewer inferences regarding the cognitive states of the story characters. These differences in the narrative task emerged even though children with PL did not differ from TD children on vocabulary and syntax tasks outside the narrative context. Thus, findings suggest that there may be limitations to the plasticity for language functions displayed by children with PL, and that these limitations may be most apparent in complex, decontextualized language tasks such as narrative production. 相似文献

The principle of absolute sovereignty may have been consigned to history, but a strong presumption against foreign intervention
seems to have been left in its stead. On the dominant view, only massacre and ethnic cleansing justify armed intervention,
these harms must be already occurring or imminent, and the prudential constraints on war must be satisfied. Each of these
conditions has recently come under pressure. Those looking to defend the dominant view have typically done so by invoking
international peace and stability, or the value of communal self-determination. But the internal aspect of legitimacy has been overlooked in all of this. If a government insists on defending the human rights of foreigners,
it must also be sure not to violate the rights of its own citizens in the process. I argue that the current presumption against
humanitarian intervention cannot be substantially relaxed for internal reasons, or given the obligations that states owe to
their own constituents. 相似文献

There is ample evidence that humans (and other primates) possess a knowledge instinct—a biologically driven impulse to make coherent sense of the world at the highest level possible. Yet behavioral decision‐making data suggest a contrary biological drive to minimize cognitive effort by solving problems using simplifying heuristics. Individuals differ, and the same person varies over time, in the strength of the knowledge instinct. Neuroimaging studies suggest which brain regions might mediate the balance between knowledge expansion and heuristic simplification. One region implicated in primary emotional experience is more activated in individuals who use primitive heuristics, whereas two areas of the cortex are more activated in individuals with a strong knowledge drive: one region implicated in detecting risk or conflict and another implicated in generating creative ideas. Knowledge maximization and effort minimization are both evolutionary adaptations, and both are valuable in different contexts. Effort minimization helps us make minor and routine decisions efficiently, whereas knowledge maximization connects us to the beautiful, to the sublime, and to our highest aspirations. We relate the opposition between the knowledge instinct and heuristics to the biblical story of the fall, and argue that the causal scientific worldview is mathematically equivalent to teleological arguments from final causes. Elements of a scientific program are formulated to address unresolved issues. 相似文献

Based on a three-dimensional model of self-construal (independent, collective interdependent, and relational interdependent self-construal), the present study investigated whether self-construal systematically related to exchange and communal orientation with data (357 participants) collected in Taiwan ( N = 178) and the USA ( N = 179). United States participants scored significantly higher on all scales except for relational interdependent self-construal. Females exhibited significantly higher scores for relational interdependent self-construal and communal orientation. As predicted, independent self-construal was related to exchange orientation and relational interdependent self-construal was related to communal orientation. However, in contrast to what was expected, collective interdependent self-construal was only marginally related to communal orientation. The findings for scales revised for validity were compared with scales including all items. This comparison disclosed differences for exchange orientation. 相似文献
