婴幼儿消极行为特征与影响母亲抚养困难的因素

以５７２名１－６岁儿童的母亲为研究对象,探讨了婴幼儿消极行为特征在各年龄组的分布、与母亲抚养困难的关系,并考察了在儿童消极行为较多情况下,与母亲抚养困难有关联的若干因素。结果表明;１．儿童消极行为特征的分布在各年龄组水平上是相似的。２．儿童的消极行为特征与母亲的抚养困难有显著的正相关。３．在儿童消极行为较多的情况下,母亲的职业、文化程度、生产年龄、婚姻关系及获得社会支持的程度等因素与母亲抚养困难有密切的关系。     

Perceived mother‐infant relationship difficulties in postnatal depression

Postnatal depression has been associated with mother–infant relationship difficulties, but there has been less research in clinical populations. This study aims to identify characteristics of reported mother–infant relationship difficulties in mothers with postnatal depression who had been referred to a tertiary Mother and Baby Service. Forty‐one mothers with postnatal depression completed self‐report and interview measures with regards to their mental state, social adversity, and perceptions on their relationship with their infants. Almost one‐third of mothers (31.7%) reported severe difficulties, including rejection of the infant and maternal pathological anger. A low birth weight and maternal dissatisfaction towards their social role were found to be significantly related to perceived mother–infant interaction difficulties. Self‐reports correlated satisfactorily with interview schedules. A significant proportion of mothers reported difficulties in relating to their infants which can be reliably identified by means of the self‐report measures used.

A model of academic enablers and mathematics achievement in the elementary grades

The purpose of this study was to test a model of the relations between specific academic enablers (motivation, interpersonal skills, engagement, and study skills) and mathematics achievement. Using teacher judgments of academic enablers and achievement, we examined the fit of this model for primary (Grades K-2) and intermediate (Grades 3-6) samples of elementary students. The results of structural equation modeling analyses indicated that prior achievement and interpersonal skills predict motivation, which then predicts study skills and engagement. These latter skills, in turn, are positively associated with academic achievement. Differences in magnitude of specific model pathways, however, were noted between the primary and intermediate samples. Implications of the findings and directions for future research regarding models of academic enablers are discussed.

Learning new problem-solving strategies leads to changes in problem representation

Children sometimes solve problems incorrectly because they fail to represent key features of the problems. One potential source of improvements in children's problem representations is learning new problem-solving strategies. Ninety-one 3rd- and 4th-grade students solved mathematical equivalence problems (e.g., 3 + 4 + 6 = 3 + __) and completed a representation assessment in which they briefly viewed similar problems and either reconstructed each problem or identified it in a set of alternatives. Experimental groups then received a lesson about one or both of two solution strategies, the equalize strategy and the add–subtract strategy. A control group received no instruction. All children completed posttest assessments of representation and problem solving. Children taught the equalize strategy improved their problem representations more than those not taught it. This pattern did not hold for the add–subtract strategy. These results indicate that learning new strategies is one source of changes in problem representation. However, some strategies are more effective than others at promoting accurate problem representation.     

The predictive value of numerical magnitude comparison for individual differences in mathematics achievement

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.     

Children’s mapping between symbolic and nonsymbolic representations of number

When children learn to count and acquire a symbolic system for representing numbers, they map these symbols onto a preexisting system involving approximate nonsymbolic representations of quantity. Little is known about this mapping process, how it develops, and its role in the performance of formal mathematics. Using a novel task to assess children’s mapping ability, we show that children can map in both directions between symbolic and nonsymbolic numerical representations and that this ability develops between 6 and 8 years of age. Moreover, we reveal that children’s mapping ability is related to their achievement on tests of school mathematics over and above the variance accounted for by standard symbolic and nonsymbolic numerical tasks. These findings support the proposal that underlying nonsymbolic representations play a role in children’s mathematical development.     

Exploring the impact of phonological awareness, visual–spatial working memory, and preschool quantity–number competencies on mathematics achievement in elementary school: Findings from a 3-year longitudinal study

This longitudinal study explored the importance of kindergarten measures of phonological awareness, working memory, and quantity–number competencies (QNC) for predicting mathematical school achievement in third graders (mean age 8 years 8 months). It was found that the impact of phonological awareness and visual–spatial working memory, assessed at 5 years of age, was mediated by early QNC, which predicted math achievement in third grade. Importantly, and confirming our isolated number words hypothesis, phonological awareness had no impact on higher numerical competencies (i.e., when number words needed to be linked with quantities [QNC Level II and above]) but predicted basic numerical competencies (i.e., when number words were isolated from quantities [QNC Level I]), explaining the moderate relationship between early literacy development and the development of mathematical competencies.     

The perils of double consciousness: The role of thought suppression in stereotype threat

The goal of the present research is to demonstrate, and then alleviate, the role of thought suppression in depressing women’s math performance under stereotype threat. We hypothesize that when taking a math test, women (but not men) attempt to suppress thoughts of the math-related gender stereotype. Suppression leads to underperformance when it uses up cognitive resources. In Study 1, women underperform on a math test and show postsuppressional rebound of the stereotype when cognitive resources are reduced. In Study 2, women suppress the stereotype after a math test begins, but show rebound when the test is complete. In Study 3, making the stereotype irrelevant to the test improves performance and reduces postsuppressional rebound. In Studies 4 and 5, we test a strategy women can use to make suppression easier, and show that it restores math performance. Theoretical and practical implications are discussed.     

Perceived benefits of using an Internet-based interactive career planning system

Making Better Career Decisions (MBCD) is an Internet-based interactive career planning system designed to help deliberating individuals. The present research examined the benefits of a dialogue with MBCD, by analyzing 712 users’ perceptions of its contribution to their career decision-making process, and locating variables associated with these perceptions. A pre-dialogue and a post-dialogue questionnaire were used to collect the users’ perceptions of its benefits and measure the change in the degree of decidedness. Perceived benefit was derived from participants’ ratings of the degree of progress they had made in their career decision-making process, whether they had learned about additional factors to be considered and their career-related preferences, as well as their ratings of the quality of the list of “promising” career alternatives presented to them during their dialogue with MBCD. This composite perceived benefit was found to be positively associated with the users’ decidedness at the completion of the dialogue with MBCD. Users’ satisfaction with the length and variety of their personal “promising alternatives” list was associated with a higher perceived benefit.
