The predictive value of numerical magnitude comparison for individual differences in mathematics achievement 总被引:2,自引:0,他引:2

Although it has been proposed that the ability to compare numerical magnitudes is related to mathematics achievement, it is not clear whether this ability predicts individual differences in later mathematics achievement. The current study addressed this question in typically developing children by means of a longitudinal design that examined the relationship between a number comparison task assessed at the start of formal schooling (mean age = 6 years 4 months) and a general mathematics achievement test administered 1 year later. Our findings provide longitudinal evidence that the size of the individual’s distance effect, calculated on the basis of reaction times, was predictively related to mathematics achievement. Regression analyses showed that this association was independent of age, intellectual ability, and speed of number identification. 相似文献

The present study explored the viability of Kivnick's 5-factor model of grandparental meaning (Kivnick, 1983), wherein this model was tested and subsequently refined on a sample of traditional grandparents (N = 102), and then cross-validated using a sample of custodial grandparents (N = 101). The data suggested that Kivnick's model of grandparental meaning was untenable in both grandparent samples. Instead, a single-factor model was supported in both samples. This suggests that grandparental meaning is best understood without regard to Kivnick's distinctions (Kivnick, 1983). This may reflect a cohort effect in the meaning of grandparenting, as evidenced in the diversity of roles into which grandparents are thrust, increased role confusion, as well as the idiosyncratic manner in which grandparents are often forced to define their roles in today's society. 相似文献

The global neuronal workspace theory [Dehaene, S., & Naccache, L. (2001). Towards a cognitive neuroscience of consciousness: basic evidence and a workspace framework. Cognition, 79, 1–37.] proposes that it is impossible for an unconscious stimulus to be used strategically to enhance task performance (bottom–up effect), while a fully consciously perceived stimulus can be used to improve task performance (top–down effect). Two experiments were designed to investigate these hypotheses. In a first experiment we investigated whether a manipulation of the proportion of Arabic/number word targets had a top–down effect. Since the subjects were fully aware of the target, we expected that this manipulation could be used to enhance task performance. In a second experiment we determined whether a manipulation of the proportion of Arabic/number word primes had a bottom–up effect. Since the subjects were unaware of the prime, we hypothesized that they would be unable to use the manipulation to enhance task performance and therefore the manipulation would have no effect. Both hypotheses were largely confirmed. 相似文献

There is an ongoing debate about how supervisors should communicate desired end‐states to subordinates, that is, whether they should set concrete goals (according to goal setting theory) or communicate abstract visions (according to transformational leadership theory). In this paper, we draw on construal level theory (CLT) to reconcile both views and develop a model of when supervisors communicating concrete goals versus abstract visions are seen as more effective. According to CLT, being psychologically removed from (vs. near to) an event or object makes people construe the event or object in a more abstract (vs. concrete) way, which, in turn, leads people to process abstract (vs. concrete) information more fluently and thus evaluate the sender of this information more favorably. Accordingly, supervisor effectiveness may be higher in conditions where communication and psychological distance to the supervisor converge (vision/far and goals/close) rather than diverge (vision/close and goals/far). We tested this hypothesis in two experiments, using different operationalizations of psychological distance. In these studies, we found supervisor effectiveness to be higher when vision was communicated at a far versus near distance and goals were communicated at a near versus far distance. 相似文献

Research has suggested the importance of applicants' expectations of forthcoming selection procedures in predicting how applicants react to selection procedures. Validated measures of selection expectations are still scarce, however. This study reports on the validation of the Applicant Expectation Survey (AES), intended to measure applicants' expectations of forthcoming selection procedures. The AES was validated using three military applicant samples and showed sound psychometric properties (i.e., reliability, measurement invariance, discriminant validity) for a five‐factorial oblique structure consisting of 26 items. The five factors (i.e., Warmth/respect, Chance to demonstrate potential, Difficulty of faking, Unbiased assessment, Feedback) were positively related to several organizational outcome measures and to applicants' perceptions of the selection procedure, providing evidence for the predictive validity of the AES. 相似文献

Test anxiety has received limited attention in personnel selection research, although it may impair the test performance of applicants. This paper describes the development and validation of a new two‐dimensional measure of applicants' test anxiety, namely the Self‐ versus Other‐Referenced Anxiety Questionnaire (SOAQ), that embeds worrisome cognitions of anxious applicants in the social evaluative context of ‘self’ (Self‐Referenced Anxiety) and ‘significant others’ (Other‐Referenced Anxiety). An exploratory factor analysis (calibration sample), followed by a confirmatory factor analysis (validation sample) and correlations with several proximal and distal theoretical constructs indicated satisfactory psychometric properties and construct validity for both SOAQ scales. Structural equation modeling further showed a differential impact of Self‐ and Other‐Referenced Anxiety on applicants' test performance within a real personnel selection context. The scientific and practical relevance of these findings are discussed. 相似文献

Collaborative problem solving may be used by older couples to optimize cognitive functioning, with some suggestion that older couples exhibit greater collaborative expertise. The study explored age differences in 2 aspects of collaborative expertise: spouses' knowledge of their own and their spouse's cognitive abilities and the ability to fit task control to these cognitive abilities. The participants were 300 middle-aged and older couples who completed a hypothetical errand task. The interactions were coded for control asserted by husbands and wives. Fluid intelligence was assessed, and spouses rated their own and their spouse's cognitive abilities. The results revealed no age differences in couple expertise, either in the ability to predict their own and their spouse's cognitive abilities or in the ability to fit task control to abilities. However, gender differences were found. Women fit task control to their own and their spouse's cognitive abilities; men only fit task control to their spouse's cognitive abilities. For women only, the fit between control and abilities was associated with better performance. The results indicate no age differences in couple expertise but point to gender as a factor in optimal collaboration. 相似文献
