Introduction: Chronic use of opiates is associated with a wide range of neuropsychological deficits. Therefore, this study aimed to evaluate one of the neuropsychological functions, updating function of working memory, in three groups, including substance abusers (heroin and opium), those under ...
Working memory (WM) for sign language has an architecture similar to that for speech-based languages at both functional and neural levels. How-ever, there are some processing differences between language modalities that are not yet fully explained, although a number of hypotheses have been mooted....
工作记忆(working memory) 工作记忆是指将信息保存在大脑中,并且将这些信息在头脑中加工、处理。暂时记忆只储存,不加工。信息在头脑中加工、处理是工作记忆和暂时记忆(short termmemory)不同之处。有了工作记忆我们才能够学习和运用语言,我们通过调出存储在记忆中的字,来组成词,再造句,再组成段落和文章,这些都需要工...
Dementia research suggests executive dysfunction is best understood within the context of disease-specific neuropathology. Leukoaraiosis (LA) results in executive dysfunction yet little is known about its impact on specific aspects of working memory (WM). This study aimed to investigate the relationship...
Blair equates the constructs of working memory (WM), executive function, and general fluid intelligence (gF). We argue that there is good reason not to equate these constructs. We view WM and gF as separable but highly related, and suggest that the mechanism behind the relationship is control...
The human working memory system provides an experimentally useful model for examination of neural overload effects on subsequent functioning of the overloaded system. This study employed functional magnetic resonance imaging in conjunction with a parametric working memory task to characterize the behavioral ...
Bipolar disorder Healthy controls fMRI Working memory Systematic review Meta-analysis 1. Introduction Bipolar disorders (BD) are serious mental health disorders associated with reduced quality of life (Sylvia et al., 2017) and high societal, as well as individual, burden (Cloutier et al., 2018; ...
Systems that supported operators with higher levels of information-analysis and decision-selection automation had varying effects on human performance and situation awareness. The authors investigated whether information-processing and working-memory abilities moderate the effects of automation on human performan...
Physical exercise enhances prefrontal cortex activity and improves working memory performance in healthy older adults, but it is not clear whether this remains the case in post-stroke patients. Therefore, the aim of this study was to examine the acute effect of physical exercise on prefrontal cortex...
Threat-related stimuli are strong competitors for attention, particularly in anxious individuals. We used functional magnetic resonance imaging (fMRI) with healthy human volunteers to study how the processing of threat-related distractors is controlled a
