Synaptic Correlates of Working Memory Capacity
Psychological studies indicate that human ability to keep information in readily accessible working memory is limited to four items for most people. This extremely low capacity severely limits execution of many cognitive tasks, but its neuronal underpinnings remain unclear. Here we show that in the framework of synaptic theory of working memory, capacity can be analytically estimated to scale w...
متن کاملThe Effect of Working Memory Training on Working Memory Capacity and Performance of Novice Karateka
Objective: This study aimed to investigate the effect of working memory (WM) training on WM capacity and performance of novice karate practitioners (karateka). Methods: Research method is quasi-experimental with a pretest posttest control group design. A total of 24 karate practitioners were selected among Alborz (Alborz Province, iran) novice karateka by convenience sampling me...
متن کاملSynaptic theory of working memory.
It is usually assumed that enhanced spiking activity in the form of persistent reverberation for several seconds is the neural correlate of working memory. Here, we propose that working memory is sustained by calcium-mediated synaptic facilitation in the recurrent connections of neocortical networks. In this account, the presynaptic residual calcium is used as a buffer that is loaded, refreshed...
متن کاملEffect of Working Memory Training on the Improving Reading Performance and Working Memory Capacity in Children with Dyslexia
Introduction: In recent years, researchers have focused on students who have challenges in learning, and these problems effect on their educational process. This study aimed to investigate the effect of working memory training programs on the improving reading performance and working memory capacity in children with dyslexia. Method: The research method was quasi-experimental. In this regard 30...
متن کاملWorking memory capacity and gender
The working memory capacity (WMC) of 400 Russian college students was measured using the Tarnow Unchunkable Test [2] which tests WMC alone without requiring explicit working memory operations. We found small-sized WMC differences by gender and a u-shaped curve: the male/female ratio increases for low and high WMC. The gender proportion in each academic fields was a strong determinant of the ave...
