We used a dual-task paradigm to examine the degree to which domain-specific spatial and verbal subsystems depend on the domain-general central executive. Forty participants were asked to retain spatial or verbal information while performing a concurrent secondary task related to simple arithmetic. The secondary tasks consisted of three cognitive processes: single-digit addition, a digit-carrying operation, and digit reading. The single-digit addition and carry operation include central executive functioning, while digit reading relies solely on the phonological loop. The single-digit addition caused a performance decrement on the spatial working memory task, while the digit reading impaired performance on the verbal working memory task. The carry operation interfered with recall accuracy on both working memory tasks. The spatial working memory task was significantly correlated with the verbal working memory task only when the secondary task was more demanding on the central executive. Our results suggest that spatial working memory rather than verbal working memory is susceptible to failure of central executive functioning and that the central executive plays an important role in regulating the cognitive demands of different domains. 相似文献

采用Stroop任务和前瞻记忆双任务实验范式,比较不同自我损耗条件对被试基于时间前瞻记忆(TBPM)的影响,及其对TBPM的加工阶段和成分的作用。然后通过添加外部时钟监控条件,探讨外部时钟是否可以减少自我损耗对TBPM的消极影响,以及自我损耗对时钟监控情况的作用。结果表明:(1)在内部控制条件下,自我损耗会严重影响TBPM的表现,高损耗组的TBPM成绩显著低于低损耗组,另外,自我损耗主要干扰前瞻记忆的前瞻成分和TBPM的第三个加工阶段。(2)在外部控制条件下,自我损耗没有降低TBPM的表现,说明外部时钟可以降低自我损耗对TBPM的消极影响。(3)自我损耗使个体呈现出不同的时钟监控模式,且邻近目标时间内的时钟监控次数与TBPM成绩呈显著正相关。 相似文献

In a colour variation of the Deese–Roediger–McDermott (DRM) false memory paradigm, participants studied lists of words critically related to a nonstudied colour name (e.g., “blood, cherry, scarlet, rouge … ”); they later showed false memory for the critical colour name (e.g., “red”). Two additional experiments suggest that participants generate colour imagery in response to such colour-related DRM lists. First, participants claim to experience colour imagery more often following colour-related than standard non-colour-related DRM lists; they also rate their colour imagery as more vivid following colour-related lists. Second, participants exhibit facilitative priming for critical colours in a dot selection task that follows words in the colour-related DRM list, suggesting that colour-related DRM lists prime participants for the actual critical colours themselves. Despite these findings, false memory for critical colour names does not extend to the actual colours themselves (font colours). Rather than leading to source confusion about which colours were self-generated and which were studied, presenting the study lists in varied font colours actually worked to reduce false memory overall. Results are interpreted within the framework of the visual distinctiveness hypothesis. 相似文献

ABSTRACT Long-term memory retrieval ability and working memory can share attention control ability. Based on cognitive plasticity, a hypothesis that cognitive training could improve long-term memory retrieval efficiency and that this could transfer to retrieval involving working memory was proposed. 60 undergraduates were randomly assigned to a group of training and an active control group; all the participants completed the same tasks in the same order before and after the training, the tasks included a long-term memory retrieval access task, a intelligence test, a switching task, a working memory updating task, a response inhibition task and an interference control task. The statistics results indicate that cognitive training can improve long-term memory retrieval efficiency and has a transfer effect on working memory updating, interference control and switching ability, but not on response inhibition or intelligence. This reveal the plasticity of long-term memory retrieval and its influence on working memory. 相似文献

The theory of signal detection is convenient for measuring mnemonic ability in recognition memory paradigms. In these paradigms,
randomly selected participants are asked to study randomly selected items. In practice, researchers aggregate data across
items or participants or both. The signal detection model is nonlinear; consequently, analysis with aggregated data is not
consistent. In fact, mnemonic ability is underestimated, even in the large-sample limit. We present two hierarchical Bayesian
models that simultaneously account for participant and item variability. We show how these models provide for accurate estimation
of participants’ mnemonic ability as well as the memorability of items. The model is benchmarked with a simulation study and
applied to a novel data set.

本研究编制了一种用于测量儿童语音工作记忆的测验———非词复述测验,并在48名四年级小学生中初步进行信度、效度检验和项目分析。结果表明:(1)该测验有较高的重测信度;(2)该测验具有较高的结构效度和效标效度;(3)分测验二的项目难度分布比较合理,多数项目鉴别力较高,而分测验一的项目难度分布和项目鉴别力则有待于在今后的研究中进一步提高。 相似文献

前瞻记忆年老化研究的自然情境和实验室情境比较 总被引:1,自引:0,他引:1
年龄—前瞻记忆矛盾现象在实验室情境和自然情境研究中普遍存在。当任务设置为日常情境时, 前瞻记忆不受年龄影响或随年龄增长而促进, 前瞻记忆成绩可能受人格、生活方式、任务材料、提示等因素的影响; 当任务是实验室情境设置时, 与年轻被试相比, 老年被试前瞻记忆成绩一般都较差, 前瞻记忆成绩可能受回溯记忆负载、线索类型和策略控制加工的需求等因素的影响。年龄-前瞻记忆矛盾现象可能来自于环境与意向的社会性特征、认知资源分配策略等方面的原因。最后, 从被试控制、任务材料的设置、动机因素的探索等方面对今后的研究提出建议和展望。 相似文献

左前额叶参与非相关词对的语义编码过程──来自光学成像的佐证 总被引:8,自引:0,他引:8
通过研究左前额叶在非相关同对的语义编码过程中的作用,探讨近红外光学成像技术用于脑高级认知活动检测的可行性。被试在两种实验条件下分别学习视觉呈现的20个汉字非相关词对,要求被试或将词对组成一个有意义的句子(深加工),或判断两个词是否具有相同的结构组合(浅加工)。光学成像器即时记录连续光透过额骨及前额皮层后760nm和850nm的漫射光强变化,以此推测相应脑组织的血容量变化。结果表明,与浅加工相比,左下前额叶在深加工时的血容量增多,尤其是背外侧部分。 相似文献
