Kyttälä, M., Aunio, P. & Hautamäki, J. (2010). Working memory resources in young children with mathematical difficulties. Scandinavian Journal of Psychology, 51 , 1–15.
Working memory (WM) ( Baddeley, 1986, 1997 ) is argued to be one of the most important cognitive resources underlying mathematical competence ( Geary, 2004 ). Research has established close links between WM deficits and mathematical difficulties. This study investigated the possible deficits in WM, language and fluid intelligence that seem to characterize 4- to 6-year-old children with poor early mathematical skills before formal mathematics education. Children with early mathematical difficulties showed poor performance in both verbal and visuospatial WM tasks as well as on language tests and a fluid intelligence test indicating a thoroughly lower cognitive base. Poor WM performance was not moderated by fluid intelligence, but the extent of WM deficits was related to language skills. The educational implications are discussed. 相似文献

Dynamical models based on three steady‐state equations for the law of effect were constructed under the assumption that behavior changes in proportion to the difference between current behavior and the equilibrium implied by current reinforcer rates. A comparison of dynamical models showed that a model based on Navakatikyan's (2007) two‐component functions law‐of‐effect equations performed better than models based on Herrnstein's (1970) and Davison and Hunter's (1976) equations. Navakatikyan's model successfully described the behavioral dynamics in schedules with negative‐slope feedback functions, concurrent variable‐ratio schedules, Vaughan's (1981) melioration experiment, and experiments that arranged equal, and constant‐ratio unequal, local reinforcer rates. 相似文献

Child abuse can negatively affect neurobiological systems involved in regulating emotions. Adults who were maltreated as children show diminished capacity to flexibly integrate the prefrontal and limbic circuits underlying emotion regulation. Using a facial identification Stroop task with nonemotional and emotional stimuli, we found that women who reported more childhood abuse (N = 44) were no different from women reporting less childhood abuse (N = 45) on nonemotional conflict adaptation, but were significantly less able to adapt to emotional conflict. Women who reported more abuse were especially impaired in adapting to emotional conflict when incongruent stimuli involved a fearful face. These results help characterize the relation between cognitive control and emotion regulation and highlight the far-reaching effects of childhood abuse on cognitive-emotional flexibility. 相似文献

The twenty-first century is certainly in progress by now, but hardly well underway. Therefore, I will take that modest elasticity in concept as a frame for this essay. This frame will serve as background for some of my hopes and gripes about contemporary psychology and mathematical psychology’s place therein. It will also act as platform for earnest, if wistful thoughts about what might have (and perhaps can still) aid us in forwarding our agenda and what I see as some of the promising avenues for the future. I loosely structure the essay into a section about mathematical psychology in the context of psychology at large and then a section devoted to prospects within mathematical psychology proper. The essay can perhaps be considered as in a similar spirit, although differing in content, to previous editorial-like reviews of general or specific aspects of mathematical psychology such as [Estes, W. K. (1975). Some targets for mathematical psychology. Journal of Mathematical Psychology, 12, 263-282; Falmagne, J. C. (2005). Mathematical psychology: A perspective. Journal of Mathematical Psychology, 49, 436-439; Luce, R. D. (1997). Several unresolved conceptual problems of mathematical psychology.

即便在相同的情形中, 每个人所做的决策也有千差万别, 导致决策个体差异的因素之一就是数学能力。文章综述了算术能力、数量表征、概率推理能力以及数学认知启发式对各种决策的影响。目前这方面的研究或者采用相关范式将数学能力作为决策的外部关联因素, 或者采用成分范式确定决策过程所需要的特定数学认知成分; 观点上的主要争论在于是一般认知能力还是数学能力在预测决策表现, 以及数学能力是否总是对决策有积极作用; 此外, 双系统模型和模糊痕迹理论有望为决策的个体差异提供理论解释。今后研究应该澄清上述争论, 确定合适的研究范式和结果解释框架, 并探讨更多提高决策能力的措施。 相似文献

本研究考察了226名大、中学生的气质类型与学业成就的关系,结果发现:无论哪个学习年限段的学生的气质类型中,与胆汁质、抑郁质有关的气质类型与学业不良有关。并认为其主要以任务坚持性和社会灵活性缺乏为特征影响学业不良学生的学习成就。 相似文献

The present research describes the development and psychometric evaluation of a second version of the Acceptance and Action Questionnaire (AAQ-II), which assesses the construct referred to as, variously, acceptance, experiential avoidance, and psychological inflexibility. Results from 2,816 participants across six samples indicate the satisfactory structure, reliability, and validity of this measure. For example, the mean alpha coefficient is .84 (.78–.88), and the 3- and 12-month test–retest reliability is .81 and .79, respectively. Results indicate that AAQ-II scores concurrently, longitudinally, and incrementally predict a range of outcomes, from mental health to work absence rates, that are consistent with its underlying theory. The AAQ-II also demonstrates appropriate discriminant validity. The AAQ-II appears to measure the same concept as the AAQ-I (r = .97) but with better psychometric consistency. 相似文献

Background and objectives: Individuals with social anxiety disorder have often been considered inflexible in their emotion regulation. The aim of this study was to investigate emotion regulation flexibility in socially anxious individuals in response to two contextual factors, namely different levels of emotion intensity and emotion type.Methods: A daily diary approach was employed, investigating emotion regulation (i.e., experiential avoidance, expressive suppression and cognitive reappraisal) in college students scoring high (N?=?62; HSA) and low (N?=?52; LSA) on social anxiety.Results: Results revealed that HSAs were found to use more experiential avoidance than LSAs, especially at higher levels of negative intensity. The use of this emotion regulation strategy appeared to be driven by guilt, nervousness, and sadness. There were no between-group differences concerning the other strategies in response to varying levels of emotional intensity.Conclusions: Together, the results provide evidence for inflexible emotion regulation in HSAs, reflected in an unwillingness to experience negative emotions. 相似文献

认知灵活性作为执行功能的三个主要成分之一,对个体能力发展和环境适应起着重要作用。但以往研究多采用不同范式来考察不同年龄段儿童在一个优势规则失效后灵活转换至新规则的能力。本研究旨在威斯康星卡片分类任务(WCST)的基础上设计一种新任务范式,考察年龄范围更大的群体在规则习得过程中根据不同性质的反馈信息保持与灵活修订假设的能力。我们设计了目标选择任务(target choose task,TCT),考察181名5~11岁儿童的认知灵活性。其中24名儿童亦完成WCST。结果表明,TCT通过率界于32~65.7%;TCT高分组成绩显著高于低分组;分半信度计算结果表明奇数编号题目与偶数题目得分正相关;TCT分数与WCST完成分类数和概念化水平数分别呈正相关。这些结果表明TCT难度适中,具有区分度,内部一致性高,效度良好,可以在更大的年龄跨度上研究儿童在规则习得过程中的认知灵活性。 相似文献
