A right-neglect patient with focal left-hemisphere damage to the posterior superior parietal lobe was assessed for numerical knowledge and tested on the bisection of numerical intervals and visual lines. The semantic and verbal knowledge of numbers was preserved, whereas the performance in numerical tasks that strongly emphasize the visuo-spatial layout of numbers (e.g. number bisection) was impaired. The behavioral pattern of error in the two bisection tasks mirrored the one previously described in left-neglect patients. In other words, our patient misplaced the subjective midpoint (numerical or visual) to the left as function of the interval size. These data, paired with the patient's lesion site are strictly consistent with the tripartite organization of number-related processes in the parietal lobes as proposed by Dehaene and colleagues. According to these authors, the posterior superior parietal lobe on both hemispheres underpins the attentional orientation on the putative mental number line, the horizontal segment of the intraparietal sulcus is bilaterally related to the semantic of the numerical domain, whereas the left angular gyrus subserves the verbal knowledge of numbers. In summary, our results suggest that the processes involved in the navigation along the mental number line, which are related to the parietal mechanisms for spatial attention, and the processes involved in the semantic and verbal knowledge of numbers, are dissociable. 相似文献

This research aimed to investigate the time course effect of a moderate steady-state exercise session on response execution and response inhibition using a stop-task paradigm. Ten participants performed a stop-signal task whilst cycling at a carefully controlled workload intensity (40% of maximal aerobic power), immediately following exercise and 30 min after exercise cessation. Results showed that moderate exercise enhances a subjects’ ability to execute responses under time pressure (shorter Go reaction time, RT without a change in accuracy) but also enhances a subjects’ ability to withhold ongoing motor responses (shorter stop-signal RT). The present outcomes reveal that the beneficial effect of exercise is neither limited to motor response tasks, nor to cognitive tasks performed during exercise. Beneficial effects of exercise remain present on both response execution and response inhibition performance for up to 52 min after exercise cessation. 相似文献

以124名处于不同戒除时相的男性海洛因戒除者为被试, 采用金钱和海洛因延迟折扣任务(DDT), 并以基于线索暴露的渴求感测量为效度指标, 探讨了该类人群对海洛因延迟强化超快速折扣倾向及其心理机制。结果发现: (1) 相对于金钱延迟强化, 戒除者对海洛因延迟强化表现出显著的超快速折扣倾向, 且该倾向不随戒除期的延长而改变; (2) 戒除者对海洛因延迟强化的超快速折扣行为可能是其冲动性特质与海洛因相关线索共同作用的结果, 海洛因相对于金钱折扣率的增量部分可能反映了海洛因及其相关线索对该类人群主观渴求感的诱发效应。 相似文献

In a recent paper, Jiri Benovsky argues that the bundle theory and the substratum theory, traditionally regarded as ‘deadly
enemies’ in the metaphysics literature, are in fact ‘twin brothers’. That is, they turn out to be ‘equivalent for all theoretical
purposes’ upon analysis. The only exception, according to Benovsky, is a particular version of the bundle theory whose distinguishing
features render unappealing. In the present reply article, I critically analyse these undoubtedly relevant claims, and reject
them.

In this study adults performed numerical and physical size judgments on a symbolic (Arabic numerals) and non-symbolic (groups
of dots) size congruity task. The outcomes would reveal whether a size congruity effect (SCE) can be obtained irrespective
of notation. Subsequently, 5-year-old children performed a physical size judgment on both tasks. The outcomes will give a
better insight in the ability of 5-year-olds to automatically process symbolic and non-symbolic numerosities. Adult performance
on the symbolic and non-symbolic size congruity tasks revealed a SCE for numerical and physical size judgments, indicating
that the non-symbolic size congruity task is a valid indicator for automatic processing of non-symbolic numerosities. Physical
size judgments on both tasks by children revealed a SCE only for non-symbolic notation, indicating that the lack of a symbolic
SCE is not related to the mathematical or cognitive abilities required for the task but instead to an immature association
between the number symbol and its meaning. 相似文献

首先对143名11岁儿童进行认知风格测验,从中选取反省型和冲动型认知风格儿童各30名,采用序列学习研究范式,对其内隐学习进行了实验研究,结果表明:(1)虽然冲动型儿童序列学习的反应时显著低于反省型儿童,但采用“比例测量法”的方差分析两组被试无显著差异。(2)采用“对立法”对包含和排除的生成成绩进行方差分析,无论反省型儿童还是冲动型儿童,其包含和排除成绩均没有显著差异,而且成绩均在几率水平以下。说明两种认知风格儿童的序列学习没有差异,且都具有内隐性。 相似文献

虚拟社会关系的心理学研究及展望 总被引:4,自引:0,他引:4
随着计算机及网络的普及,一种新型的、不同于传统“面对面(facetoface)”交往的社会关系——虚拟社会关系(virtualsocialrelationship)——已逐渐形成。该文从心理学角度对虚拟交往的动机、影响虚拟关系发展的因素及“虚拟”与“现实”的关系等进行了阐述,并在此基础上对未来虚拟社会关系的研究取向进行了展望,认为虚拟社会关系形成的心理基础、心理机制等将成为今后的研究热点 相似文献
