回溯线索范式在视觉工作记忆相关研究中被广泛用于提高工作记忆效能,前人研究已经证实了时间序列线索在工作记忆提取过程中的促进效应。然而,记忆负荷与时间序列线索的交互作用依然有待探索。当前研究采用工作记忆的变化检测任务结合回溯线索范式,考察记忆项目负荷变化对时间序列线索效应的影响。实验设计连续呈现两个记忆阵列,并使用序列线索提取指定的记忆阵列来考察线索对记忆表征的提取效应。结果表明:在高负荷与低负荷条件下都可以观测到序列线索效应,并且序列线索效应会随记忆负荷变化,记忆负荷的上升会减弱线索效应。该研究评估了不同负荷条件下序列线索对视觉工作记忆表征的加强,加深了对时间序列线索作用机制的理解,并拓展了时间序列线索在视觉工作记忆中的应用范围。  相似文献

心智游移(mind-wandering,简称MW)是指个体将部分或全部注意转向了内部体验和感受,是一种注意分散状态。通过n-back任务以及go/no-go任务,考察工作记忆广度、工作记忆负载和目标出现概率等因素对MW的影响,借助Broadbent等人编制的认知失败问卷进行实验室情境下MW发生率与实际生活中的分心现象的相关性研究,结果发现:在高负载水平下,被试的MW报告率显著低于低负载水平,高广度组被试比低广度组被试报告更少的MW;目标呈现概率与工作记忆负载存在交互作用,二者共同影响MW报告率;在高负载水平下,目标呈现概率无论大小,MW报告率都较小,而在低负载水平下,目标呈现概率高时MW报告率更小;MW报告率与反应抑制正确率存在负相关,说明MW的发生对于任务反应存在消极影响;MW报告率与个体在CFQ问卷上的得分存在正相关。我们认为心智游移受工作记忆资源的影响,并且实验室情况下的MW与日常生活中的MW具有一定程度的相关。  相似文献

The effect of test anxiety on learning superficial and deep level tasks was examined. Ninety college students classified as either high or low test-anxious learned a paired-associate word list using either a superficial level or a deep level processing strategy. The results indicated that on the superficial level processing task, the performance of the low test-anxious students was not significantly different from that of the high test-anxious students, while on the deep level processing task the performance of the low test-anxious students was significantly better than the performance of the high test-anxious students. The results are discussed in the context of a cognitive-attentional theory of test anxiety and the mechanisms by which test anxiety may disrupt performance.  相似文献

The term ‘modality effect’ in multimedia learning means that students learn better from pictures combined with spoken rather than written text. The most prominent explanations refer to the split attention between visual text reading and picture observation which could affect transfer of information into working memory, maintenance of information in working memory or the effective size of working memory. The assumption of a continuous need for split attention is questionable, however. Learners can keep pictorial information in working memory, when they have seen the picture before, especially if they have higher prior knowledge. Instead of suffering from a permanent split attention, learners frequently show tendencies to simply ignore pictures. This suggests guiding learners towards picture analysis by picture-related text paragraphs. We assume that these paragraphs are associated with stronger modality effects than content-related paragraphs, especially if the pictures are new to learners. These assumptions were tested in an experiment with 120 students learning about volcanism from illustrated text consisting of segments each including a content-related paragraph followed by a picture-related paragraph describing the accompanying visualization. Content-related and picture-related paragraphs were presented as visual or auditory texts leading to 2x2 conditions of text presentation. Picture novelty was manipulated by presenting a picture throughout the whole segment or only when the picture-related paragraph was read. As expected, picture-related paragraphs were associated with stronger modality effects than content-related paragraphs if picture novelty is high. The distinction between different kinds of paragraphs seems to be important for the prediction of modality effects.  相似文献

The authors’ aim was to examine the relations among mental multiplication, working memory load (WML), and automaticity by alternating the difficulty level of task characteristics. In Experiment 1, involving 30 fifth-grade students with mixed abilities, a 2 (WML) × 2 (automaticity) design was utilized. In Experiment 2, involving 21 high-achieving mathematics learners and 21 low-achieving mathematics learners in Grade 4, a 2 (WML) × 2 (automaticity) × 2 (achievement) design was utilized. Regardless of level of automaticity, individuals under low-WML conditions performed more accurately and faster. Regardless of level of WML, individuals under high automaticity conditions performed more accurately and faster. Group difference was significant. The simple effect of WML was bigger under the conditions with low automaticity, in comparison to the conditions with high automaticity. Alternating difficulty level simultaneously in 2 dimensions of testing conditions posed an amplified impact on the low-achieving group.  相似文献

We investigated processes underlying performance decrements of highly test-anxious persons. Three experiments contrasted conditions that differed in the degree of activation of concepts related to failure. Participants memorized a list of words either containing words related to failure or containing no words related to failure in Experiment 1. In Experiment 2, all participants initially memorized words related to failure, but one experimental condition subsequently required the intentional forgetting of these words, thereby, decreasing the words’ activation in memory. The performance of highly test-anxious participants in unannounced cognitive ability tests following the memorizing phase profited from the activation of failure-related concepts. Experiment 3 replicated this finding by contrasting a condition priming failure–related concepts with a neutral control condition. The results point to a mechanism of suppressing worrying thoughts that is detrimental to test performances of highly test-anxious persons. Bringing the feared threat of failure to their awareness prevents that suppression.  相似文献

The motor control of 49 unmedicated boys clinically diagnosed with ADHD, case‐matched with 49 non‐ADHD boys, was assessed while playing Crash Bandicoot I, a SonyTM Playstation platform computer video game. In Crash Bandicoot participants control the movements of a small‐animated figure through a hazardous jungle environment. Operationally defined measures of motor control were designated by (1) the stage of the game completed (ie, the number of obstacles successfully passed) before losing the figure's ‘life’, (2) the level of complexity that the stage represented and (3) the time taken to get to that point during the video game play. These measures were assessed under contrasting conditions of low or high working memory and distracter loads. Four tasks were administered (totalling 12 trials), incorporating both with and without distracter conditions. For those trials with the distracter, a segment of the television show The Simpsons was simultaneously played on a television screen adjacent to the computer game monitor. A 5‐way MANOVA revealed that ADHD boys took less time to complete their trials under the direct condition (ie, no working memory load) on Crash Bandicoot, compared to their matched non‐ADHD peers. When the task required additional working memory, however, the ADHD boys took significantly longer. Cumulative frequency plots of game performance revealed that in terms of the number of obstacles completed, the control participants successfully navigated more obstacles on the low working memory load task than the ADHD participants, but that the performance of the two groups was less distinguishable on the high working memory load task. The findings have implications for assessment and management of children with ADHD.  相似文献

The purpose of this study was to assess aspects of college students' organization of concepts related to emotions and their regulation during test taking. The authors also evaluated whether students who report having problems with test anxiety hold a different conceptual organization about test taking compared with students who do not report having such problems. Concepts relevant to emotions and their regulation during test taking were sampled from the emotion and emotional regulation literature. Participants rated how similar these concepts were during test taking. These ratings were then submitted to multidimensional scaling analyses (MDS). The resulting arrangement of concepts provides insight into the underlying organizational conceptions held by low, moderate, and high test-anxious participants. Students' organizational schemes surrounded 2 dimensions: (a) task-focus and (b) pleasantness. High test-anxious participants had differing conceptual organizations about test taking than moderate and low test-anxious participants with regard to pleasantness. In addition, the high test-anxious participants saw task-focused processes such as reading directions during test taking as more highly related to unpleasant emotions like anxiety than moderate and low test-anxious participants.  相似文献

There is growing evidence supporting the importance of executive functions, and specifically working memory updating (WMU), for children’s academic achievement. This study aimed to assess the specific contribution of updating to the prediction of academic performance. Two updating tasks, which included different updating components, were administered to 97 fourth-grade children. The keeping track task involves retrieval and substitution of information, while the numerical updating task also includes a transformation component. Academic attainment was assessed through standardised tests of verbal comprehension, arithmetic operations, mathematical problems and an assessment made by the teacher. The relative contribution to academic attainment, of the updating measures and measures related to intelligence, was compared. Results showed that both updating tasks are predictive measures of academic attainment, although the numerical updating task appeared to be a more consistent predictor of children’s performance. The relationship between updating and academic attainment is discussed, and possible educational implications are considered. The role of the transformation component of WMU is highlighted. This component could make a distinct and independent contribution to performance and, by extension, could be particularly relevant to the prediction of academic achievement.  相似文献
