通过数字线任务和离散物体任务对81名拥有错误整数偏向的儿童进行干预,再进行分数比较任务,以考查不同干预对错误整数偏向的影响以及分数在心理数字线上的表征方式。结果表明:(1)离散物体组儿童在干预任务中表现较好,在分数比较任务中得分也显著高于数字线组儿童,但反应时要慢于数字线组儿童。(2)正确比较分数时,两组均出现正确整数偏向,但错误的整数偏向依然存在,二者在整数系统扩展到有理数系统这个过渡期同时存在。 相似文献

本研究通过两个实验考察了整数构成对分数加工的影响。实验一重复了Bonato等(2007)的研究,要求25名被试比较1/5与1/1、1/2、1/3、1/4、1/6、1/7、1/8、1/9等分数的大小,结果发现被试采用了成分加工策略,即通过比较分母判断分数的大小。实验二改变了分数的整数构成,让24名被试比较1/5与1/1、2/4、3/9、4/16、4/24、3/21、2/16、1/9等分数的大小。这些分数与实验一中的分数实数值相等但整数构成不同。结果表明被试既采取了成分策略,又采取了整体策略,即比较分数的实数值,不过成分策略比整体策略的作用更大。这些结果表明,分数加工具有成分和整体两种策略,具体使用哪种策略与分数的整数构成密切相关。 相似文献

认知偏向是焦虑障碍患者的重要认知特征, 是指患者或高焦虑个体对负性或威胁性信息存在认知加工方面的偏向。目前该领域的研究聚焦于注意偏向和解释偏向。近年来, 研究者致力于将认知偏向的矫正应用于焦虑障碍患者的临床治疗, 得到了不一致的结果。本文总结了将认知偏向矫正应用于临床实践的不同方式, 并从主观报告的疗效证据、行为及生理指标的疗效证据, 以及未发现疗效证据的研究三方面回顾了近年来的研究成果。对于结果的高度不一致, 本文从期望效应、干预对象、因变量和其它参数等方面探讨了可能的原因, 并讨论了未来可能的研究方向。 相似文献

文章综述了惊恐障碍患者对威胁性信息的注意偏向、解释偏向、记忆偏向等认知偏向。对威胁性信息的优先注意激发焦虑体验,对模糊信息的灾难化解释增加焦虑水平,对引起焦虑感信息的记忆保持促使惊恐体验更易于提取,这3种认知偏向促使具有焦虑倾向的个体对惊恐障碍更易感,也是惊恐障碍形成和保持的关键因素 相似文献

这篇文章从进化心理学的视角阐述了认知偏向研究的方法和基本理论,进化心理学认为人类认知存在系统的偏向,这种有偏的认知通常是自然选择设计的特征.认知偏向的误差管理理论认为:如果认知在不确定条件下做出,并且错误肯定和错误否定的错误的成本在进化历史上不对称情况循环出现,自然选择偏爱犯最小成本错误的认知偏向.认知偏向研究的进化心理学方式有助于系统地产生关于领域特定化的认知偏向的预测. 相似文献

自尊的认知加工偏向研究述评 总被引:4,自引:0,他引:4
随着认识心理学的发展,人们从认知的角度对自尊进行了拓展性的研究。主要揭示不同自尊水平对认知加工偏向的影响,找出低自尊水平的认知加工特点并期望通过选择性训练来提升个体的自尊水平。关于自尊的认知加工偏向的心理机制主要是心境一致性效应和特质一致性效应。虽然这一取向的研究具有巨大的实践意义,但是还没有取得阶段性成果。 相似文献

空间偏向意指人们在注意刺激物时普遍具有方向上的偏好.对其成因,目前主要存在“大脑说”和“文化说”两派观点.前者认为大脑的不对称性是决定因素,而后者则认为阅读和书写习惯等文化因素是主要成因.本文在综述空间偏向研究后指出,以上两派学说在解释力上各有得失,但并非完全对立,将二者结合起来的“大脑-文化说”才能更好地解释空间偏向现象. 相似文献

敌意解释偏向是一种认知加工偏向, 指个体将模棱两可信息以敌意的方式进行解释的倾向, 它会对个体的攻击行为产生影响。攻击也会影响个体的敌意解释偏向:作为一种人格特质, 高攻击性使个体更容易产生敌意解释偏向; 作为一种行为反应, 攻击对敌意解释偏向具有发展和强化作用。敌意解释偏向和攻击之间可能存在循环关系。两者关系会受到性别、年龄以及人格特点等因素影响。未来研究需要改进敌意解释偏向与攻击的测量工具, 使测量更为直接、客观; 拓展两者不同亚类之间的交互研究, 以全面系统地了解两者之间的关系; 深入探究情绪在敌意解释偏向与攻击行为关系中的作用; 整合信息加工过程, 探究它们的交互作用对攻击行为的影响等。 相似文献

本研究采用数字线索提示的刺激探测任务, 通过三个实验探讨负数的低水平加工能否,以及怎样引起空间注意的转移。实验一探讨只有负数单独呈现作为线索时能否引起空间注意的转移。结果表明:对负数绝对值大小的加工能引起空间注意的转移。实验二进一步探讨在正数、负数和零混合作为线索时能否引起空间注意的转移。结果表明:对负数数量大小的加工能引起空间注意的转移。实验三再次用正数, 负数和0三种数字混合作为探测刺激前的线索, 但仅对负数和零作为提示线索之后的探测刺激进行反应, 又一次得到了由有效提示线索所引发的对数字数量大小加工引起的空间注意的转移。本研究表明, 对负数的低水平加工可以引起空间注意的转移, 然而, 是对绝对值的加工还是数量大小的加工引起注意转移依赖于共同参与的其它数字加工产生的影响。 相似文献

Mature representations of space and number are connected to one another in ways suggestive of a ‘mental number line’, but this mapping could either be a cultural construction or a reflection of a more fundamental link between the domains of number and geometry. Using a manual bisection paradigm, we tested for number line representations in adults, young school children, and preschool children. Non-symbolic numerical displays systematically distorted localization of the midpoint of a horizontal line at all three ages. Numerical and spatial representations therefore are linked prior to the onset of formal instruction, in a manner that suggests a privileged relation between spatial and numerical cognition. 相似文献

Humans represent numbers on a mental number line with smaller numbers on the left and larger numbers on the right side. A left‐to‐right oriented spatial–numerical association, (SNA), has been demonstrated in animals and infants. However, the possibility that SNA is learnt by early exposure to caregivers’ directional biases is still open. We conducted two experiments: in Experiment 1, we tested whether SNA is present at birth and in Experiment 2, we studied whether it depends on the relative rather than the absolute magnitude of numerousness. Fifty‐five‐hour‐old newborns, once habituated to a number (12), spontaneously associated a smaller number (4) with the left and a larger number (36) with the right side (Experiment 1). SNA in neonates is not absolute but relative. The same number (12) was associated with the left side rather than the right side whenever the previously experienced number was larger (36) rather than smaller (4) (Experiment 2). Control on continuous physical variables showed that the effect is specific of discrete magnitudes. These results constitute strong evidence that in our species SNA originates from pre‐linguistic and biological precursors in the brain. 相似文献

ABSTRACTMental arithmetic is characterised by a tendency to overestimate addition and to underestimate subtraction results: the operational momentum (OM) effect. Here, motivated by contentious explanations of this effect, we developed and tested an arithmetic heuristics and biases model that predicts reverse OM due to cognitive anchoring effects. Participants produced bi-directional lines with lengths corresponding to the results of arithmetic problems. In two experiments, we found regular OM with zero problems (e.g., 3+0, 3?0) but reverse OM with non-zero problems (e.g., 2+1, 4?1). In a third experiment, we tested the prediction of our model. Our results suggest the presence of at least three competing biases in mental arithmetic: a more-or-less heuristic, a sign-space association and an anchoring bias. We conclude that mental arithmetic exhibits shortcuts for decision-making similar to traditional domains of reasoning and problem-solving. 相似文献

Recent evidence has highlighted the important role that number-ordering skills play in arithmetic abilities, both in children and adults. In the current study, we demonstrated that number comparison and ordering skills were both significantly related to arithmetic performance in adults, and the effect size was greater in the case of ordering skills. Additionally, we found that the effect of number comparison skills on arithmetic performance was mediated by number-ordering skills. Moreover, performance on comparison and ordering tasks involving the months of the year was also strongly correlated with arithmetic skills, and participants displayed similar (canonical or reverse) distance effects on the comparison and ordering tasks involving months as when the tasks included numbers. This suggests that the processes responsible for the link between comparison and ordering skills and arithmetic performance are not specific to the domain of numbers. Finally, a factor analysis indicated that performance on comparison and ordering tasks loaded on a factor that included performance on a number line task and self-reported spatial thinking styles. These results substantially extend previous research on the role of order processing abilities in mental arithmetic. 相似文献

Many learners have difficulties with rational number tasks because they persistently rely on their natural number knowledge, which is not always applicable. Studies show that such a natural number bias can mislead not only children but also educated adults. It is still unclear whether and under what conditions mathematical expertise enables people to be completely unaffected by such a bias on tasks in which people with less expertise are clearly biased. We compared the performance of eighth‐grade students and expert mathematicians on the same set of algebraic expression problems that addressed the effect of arithmetic operations (multiplication and division). Using accuracy and response time measures, we found clear evidence for a natural number bias in students but no traces of a bias in experts. The data suggested that whereas students based their answers on their intuitions about natural numbers, expert mathematicians relied on their skilled intuitions about algebraic expressions. We conclude that it is possible for experts to be unaffected by the natural number bias on rational number tasks when they use strategies that do not involve natural numbers. 相似文献
