Neuroimaging studies have shown that the dorsolateral prefrontal cortex (DLPFC) is recruited during motor skill learning, which suggests the involvement of the DLPFC in working memory (WM) processes, such as selection and integration of motor representations temporarily stored in WM. However, direct evidence linking activation of the DLPFC to WM storage and manipulation during motor skill learning in real-time is rare. In this study, we conducted two experiments to investigate the causal role of DLPFC activity in WM storage and manipulation during motor skill learning under low and high WM-demand conditions. Participants received continuous theta burst stimulation (cTBS) and sham stimulation (crossover design) over the left DLPFC (experiment 1) or right DLPFC (experiment 2). Before and after stimulation, participants in both experiments performed a sequential finger-tapping (SFT) task containing repeated sequence (low-WM demand) and non-repeated sequence (high-WM demand) conditions which are used to study WM processes. The number of correct sequences (NoCS) and reproduction error rate were analyzed. Learning gains in NoCS improved significantly with the practice for both sequence types in the presence of either stimulation type. Compared to sham stimulation, cTBS over the left DLPFC resulted in significantly reduced learning gains in NoCS for non-repeated sequences. These results suggest that the left DLPFC contributes to WM manipulation during motor skill learning. 相似文献

In this paper we explore migrants' and minorities' memories and memory-making associated with death, funerary and remembrance practices, with particular attention to how this intersects with experiences of migration and/or being part of a cultural or religious minority. The paper examines different spaces including bodies, homes, translocal networks, cemeteries and crematoria, centred on insights from focus groups, biographical and key participant interviews in four medium sized multicultural towns in England and Wales. These case studies afford an exploration of the complex and dynamic ‘ecologies’ of migrant and minority memories and sense of citizenship in relation to death, bereavement and remembrance spaces and practices. Participant accounts highlight memories of past practices, (post)colonial marginalization, disenfranchisement, changes in practices, the strains of transnational grieving, pragmatic compromises and collaborating to improve funerary provision as endeavours of everyday citizenship. These are explored through two broad interlinked themes: firstly, translocal memories of past and evolving funerary and remembrance spaces, customs and practices; and secondly, relationality and autonomy through the choice of where to situate the dead, and implications for associated future memory-making. 相似文献

执行功能缺陷是网络成瘾发生、维持和复发的原因之一,以往研究侧重于探讨网络成瘾者注意控制、反应抑制等执行功能成分的损伤状况,而其记忆抑制状况尚不清楚。本研究通过考察网络成瘾大学生的提取诱发遗忘(RIF)来探讨其记忆抑制的特点及RIF的产生机制。结果发现:低网络成瘾个体在高项目竞争强度下表现出显著的RIF,在低项目竞争强度下未产生;高网络成瘾个体在低项目竞争强度下表现出显著的RIF,在高项目竞争强度下未产生。结果表明网络成瘾大学生的记忆抑制能力受损严重,其在低项目竞争强度下易受相关代价与效益问题(CCB)影响而产生干扰性RIF。 相似文献

As a clinical model of hippocampal dysfunction, transient global amnesia (TGA) causes reversible memory disturbance. While episodic memory deficits in TGA patients have been extensively described, data regarding semantic memory involvement are sparse and contradictory. We report impaired semantic fluency performance in 16 patients with hippocampal lesions on MRI during acute TGA compared to their performance one day later and to that of 20 healthy subjects. Our findings support the involvement of the hippocampus in semantic retrieval. 相似文献

Against the background of a reconstruction of the reasons for the vanishing role of remembering in the history of psychoanalysis, Botella's (2014, Int J Psychoanal, 95 ) arguments regarding the therapeutic significance of reconstruction and remembering and of the therapist's role are discussed. The difference between intellectual reconstruction and actual emotional remembering are underlined, the term regredience is compared to competing concepts such as equally suspended attention, countertransference and reverie. It is argued that to conceptualize the use of countertransferential associations for reconstructing past traumatic events is difficult with a monadic conception of the unconscious and problematic both in terms of truth claims and in terms of achieving a shared creative atmosphere in which therapist and patient participate alike. It is concluded that historical truth may be important for traumatic experiences, and that biographical reconstruction and change in the subjective life story help to make sense of neurotic patterns and integrate diachronic identity. 相似文献

The survival processing paradigm has recently drawn attention to the functional aspects of memory functioning. The survival effect, characterized by better memory performance when information is processed in a survival context, as compared with a variety of controls, is now well established in healthy populations. The main goal of this study was to test this paradigm in a group of cognitively impaired older adults and elderly; their data were compared to the data obtained in a group of healthy older adults and elderly. Seventeen cognitively impaired and 17 healthy participants performed a typical survival task using a blocked within‐subject design procedure and free recall as the memory test. The healthy older adults and elderly performed better on this memory task as well as on other tests included in a neuropsychological evaluation protocol. Importantly, both groups benefited from survival processing. These results provide further support for the power of survival processing, extending this phenomenon to cognitively impaired aging participants. The data also suggest that the survival effect is not simply a form of deep processing. Potential applied considerations are presented. 相似文献

The present study examined individual differences in susceptibility to two similar forms of memory distortion: the misinformation effect and hindsight bias. The misinformation effect occurs when individuals witness an event, are provided with misinformation, and recall the original event as containing elements of the misinformation. Hindsight bias occurs when individuals make judgments, are provided with feedback, and recall their original judgments as being more similar to the feedback than they actually were. Seventy-five participants completed a misinformation task, a hindsight bias task, and several individual difference measures related to memory distortions. Working memory capacity was negatively correlated with the misinformation effect and hindsight bias, and the misinformation effect and hindsight bias were negatively correlated with one another. Although the misinformation effect and hindsight bias are measured with similar designs, and both are predicted by working memory capacity, the negative correlation between them suggests these phenomena result from somewhat different processes. 相似文献

Accounts of comprehension failure, whether in the case of readers with poor skill or when syntactic complexity is high, have overwhelmingly implicated working memory capacity as the key causal factor. However, extant research suggests that this position is not well supported by evidence on the span of active memory during online sentence processing, nor is it well motivated by models that make explicit claims about the memory mechanisms that support language processing. The current study suggests that sensitivity to interference from similar items in memory may provide a better explanation of comprehension failure. Through administration of a comprehensive skill battery, we found that the previously observed association of working memory with comprehension is likely due to the collinearity of working memory with many other reading-related skills, especially IQ. In analyses which removed variance shared with IQ, we found that receptive vocabulary knowledge was the only significant predictor of comprehension performance in our task out of a battery of 24 skill measures. In addition, receptive vocabulary and non-verbal memory for serial order—but not simple verbal memory or working memory—were the only predictors of reading times in the region where interference had its primary affect. We interpret these results in light of a model that emphasizes retrieval interference and the quality of lexical representations as key determinants of successful comprehension. 相似文献
