There is a lot of debate in the literature with regards to whether the effects of working memory span training generalize to working memory tasks that are different from the trained task, however, there is little evidence to date supporting this idea. The present randomized controlled trial included 80 undergraduate students who were randomly assigned to either the experimental group (N = 40) or the control group (N = 40) in order to receive a working memory span intervention for 20 sessions over the course of 4 weeks. Brain electrophysiological signals during a dot pattern expectancy (DPX) task and a change detection task were recorded both before and after the intervention. The amplitudes of characteristic event-related potential (ERP) components reflecting working memory maintenance capability during the delay period of both tasks (i.e., the contingent negative variation or CNV, derived from the DPX task, and the contralateral delay activity or CDA, derived from the change detection task) were used as the primary outcome measures. Our data indicated that the intervention resulted in specific changes in both, the CNV and the CDA, suggesting that working memory span training generalized to working memory maintenance processes as observed in working memory tasks that were different from the trained task. We conclude that working memory span training might serve as a useful tool to improve working memory maintenance capability. Trial Registration: Chinese Clinical Trial Registry (chiCTR-INR-17011728).

Purpose Many perceptual processing processes, such as cognition, vision, sensation, and audition, are affected due to fatigue. Musicians are prone to fatigue because of long working hours and demandin...
Genetic factors have been suggested to affect the efficacy of working memory training. However, few studies have attempted to identify the relevant genes.
Working memory training research has produced mixed results in terms of finding benefits beyond the trained tasks (i.e., transfer). One potential limitation is that the research thus far has failed to...
Previous research suggests that the perception of stimulus onset can be accelerated by a match between the contents of visual working memory and the stimulus presented alone in the peripheral visual f...
Our aim was to determine if deficits in intentional forgetting that are associated with depression and dysphoria (subclinical depression) could be explained, at least in part, by variations in working...
According to the working memory model, which accounts for the organisation of working memory, the processing of non-meaningful gestures is not clear. Some authors suggest that working memo...
This study is an investigation of the effect of a computer-based working memory training program on memory and language processing in at-risk children (e.g., those with working memory weak...
The purpose of this study is to investigate whether working memory training improves behavioral symptoms, neurocognitive performance, and neural functioning in young children with ADHD.

Type of declarative memory, consisting of personal memory in contrast to general knowledge.
People who are in the labor force either working or looking for work for 27 weeks or more in a year, but whose income fall below a given poverty line.
A neuropsychological test designed to assess different memory functions. It may incorporate an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess memory related cognitive function.
A set of cognitive functions that controls complex, goal-directed thought and behavior. Executive function involves multiple domains, such as CONCEPT FORMATION, goal management, cognitive flexibility, INHIBITION control, and WORKING MEMORY. Impaired executive function is seen in a range of disorders, e.g., SCHIZOPHRENIA; and ADHD.
Neurological process involving the conversion of learned information into long-term memory.
