Representations of numerical and non‐numerical magnitude both contribute to mathematical competence in children 下载免费PDF全文
A growing body of evidence suggests that non‐symbolic representations of number, which humans share with nonhuman animals, are functionally related to uniquely human mathematical thought. Other research suggesting that numerical and non‐numerical magnitudes not only share analog format but also form part of a general magnitude system raises questions about whether the non‐symbolic basis of mathematical thinking is unique to numerical magnitude. Here we examined this issue in 5‐ and 6‐year‐old children using comparison tasks of non‐symbolic number arrays and cumulative area as well as standardized tests of math competence. One set of findings revealed that scores on both magnitude comparison tasks were modulated by ratio, consistent with shared analog format. Moreover, scores on these tasks were moderately correlated, suggesting overlap in the precision of numerical and non‐numerical magnitudes, as expected under a general magnitude system. Another set of findings revealed that the precision of both types of magnitude contributed shared and unique variance to the same math measures (e.g. calculation and geometry), after accounting for age and verbal competence. These findings argue against an exclusive role for non‐symbolic number in supporting early mathematical understanding. Moreover, they suggest that mathematical understanding may be rooted in a general system of magnitude representation that is not specific to numerical magnitude but that also encompasses non‐numerical magnitude. 相似文献

The aim of the current study was to create a new measure of parenting practices, constituted by items from already established measures, to advance the measurement of parenting practices in clinical and research settings. Five stages were utilized to select optimal parenting items, establish a factor structure consisting of positive and negative dimensions of parenting, meaningfully consider child developmental stage, and ensure strong psychometric properties (reliability and validity) of the final measure. A total of 1790 parents (44% fathers) were recruited online through Amazon’s Mechanical Turk for three cohorts: Stages 1 (N?=?611), 2 (N?=?615), and 3 (N?=?564). Each sample was equally divided by child developmental stage: Young childhood (3 to 7 years old), middle childhood (8 to 12 years old), and adolescence (13 to 17 years old). Through the five-stage empirical approach, the Multidimensional Assessment of Parenting Scale (MAPS) was developed, successfully achieving all aims. The MAPS factor structure included both positive and negative dimensions of warmth/hostility and behavioral control that were appropriate for parents of children across the developmental span. The MAPS demonstrated strong reliability and longitudinal analyses provided initial support for the validity of MAPS subscales. 相似文献

How long does it take for a newborn to recognize an object? Adults can recognize objects rapidly, but measuring object recognition speed in newborns has not previously been possible. Here we introduce an automated controlled‐rearing method for measuring the speed of newborn object recognition in controlled visual worlds. We raised newborn chicks (Gallus gallus) in strictly controlled environments that contained no objects other than a single virtual object, and then measured the speed at which the chicks could recognize that object from familiar and novel viewpoints. The chicks were able to recognize the object rapidly, at presentation rates of 125 ms per image. Further, recognition speed was equally fast whether the object was presented from familiar viewpoints or novel viewpoints (30° and 60° azimuth rotations). Thus, newborn chicks can recognize objects across novel viewpoints within a fraction of a second. These results demonstrate that newborns are capable of both rapid and invariant object recognition at the onset of vision. 相似文献

Despite widespread agreement that ambivalence precludes agency “at its best,” in this paper I argue that ambivalence as such is no threat to one’s agency. In particular, against “unificationists” like Harry Frankfurt I argue that failing to be fully integrated as an agent, lacking purity of heart, or being less than wholehearted in one’s choices, tells us nothing about whether an agent’s will is properly functioning. Moreover, it will turn out that in many common circumstances, wholeheartedness with respect to some motive or course of action is itself a defect in an agent’s will. 相似文献

Thai installation art provides a view into modern, non-monastic experiences of Buddhism. Buddhist practice and scholarship often depend on centuries-old ritual practices and texts, and designated religious sites and persons. However, installation art illumines a fluxing and organic Buddhism – and one that is increasingly globalised and public. An evolving artistic zeitgeist is fused with classical tenets of Buddhism and diverse spiritualties. Each with a unique flair and multi-media repertoire, artists such as Jakkai Siributr, Montien Boonma, Sarawut Duangjampa, Chalermchai Kositpipat and others are offering creative contemplations on Buddhism today. Their works are often experienced in a leisurely fashion by the attending public, amidst social outings or intellectual excursions. People are encouraged to react however they wish to installations, which are themselves fundamentally transient – lasting usually between three and six months. Buddhism is thus asserted as an on-going project: a continual discovery rather than a quest for knowledge from the past. 相似文献

When reading a text and searching for a target letter, readers make more omissions of the target letter if it is embedded in frequent function words than if it is in rare content words. While word frequency effects are consistently found, few studies have examined the impacts of passage familiarity on the missing-letter effect and studies that have present conflicting evidence. The present study examines the effects of passage familiarity, as well as the impacts of passage familiarization strategy promoting surface or deep encoding, on the missing-letter effect. Participants were familiarized with a passage by retyping a text, replacing all common nouns with synonyms, or generating a text on the same topic as that of the original text, and then completed a letter search task on the familiar passage as well as an unfamiliar passage. In Experiment 1, when both familiar and unfamiliar passages use the same words, results revealed fewer omissions for the retyping and synonyms conditions. However, in Experiment 2, when different words are used in both types of texts, no effect of familiarization strategy was observed. Furthermore, the missing-letter effect is maintained in all conditions, adding support to the robustness of the effect regardless of familiarity with the text. 相似文献

Children's emotion dysregulation and depressive symptoms are known to be affected by a range of individual (parent, child) and systemic (parent–child, marital, and family) characteristics. The current study builds on this literature by examining the unique role of coparental affect in children's emotion dysregulation, and whether this association mediates the link between parent and child depressive symptoms. Participants were 51 mother–father–child triads with children aged 7 to 12 (M age = 9.24 years). Triads discussed a time when the child felt sad and a time when the child felt happy. Maternal and paternal displays of positive affect were coded, and sequential analyses examined the extent to which parents were congruent in their displays of positive affect during the emotion discussions. Results indicated that interparental positive affect congruity (IPAC) during the sadness discussion, but not the happiness discussion, uniquely predicted parent‐reported child emotion dysregulation, above and beyond the contributions of child negative affect and parental punitive reactions. The degree of IPAC during the sadness discussion and child emotion dysregulation mediated the association between maternal, but not paternal, depressive symptoms and child depressive symptoms. Findings highlight the unique role of coparental affect in the socialization of sadness in youth and offer initial support for low levels of IPAC as a risk factor for the transmission of depressive symptoms in youth. 相似文献

Public attitudes toward abortion have long been an issue in American political debates. Theoretical understanding of influences
on abortion attitudes may assist researchers in determining contributors of the attribution. Accordingly, this study administered
a 40-item abortion opinion survey to 396 college students at a Midwestern university to determine potential factors correlated
with abortion attitudes. Several factors such as religious involvement, knowledge of someone who has an abortion, and one’s
definition as to when life begins were correlated with abortion attitudes. Furthermore, Democrats reported stronger pro-choice
views than Republicans did. Similarly, Liberals were more pro-choice oriented than Conservatives. Although causal relationships
were not directly explored, theoretical explanations and support provide for a thorough understanding of potential factors
of abortion attitude formation and a preliminary model. Future implications are also discussed. 相似文献
