Enumeration performance modulated by spatial working memory load

Stroop proactive control and task conflict are modulated by concurrent working memory load.

Performance on the Stroop task reflects two types of conflict-informational (between the incongruent word and font color) and task (between the contextually relevant color-naming task and the irrelevant, but automatic, word-reading task). According to the dual mechanisms of control theory (DMC; Braver, 2012), variability in Stroop performance can result from variability in the deployment of a p...

Visuo-spatial Working Memory

Modulation of slow brain potentials by working memory load in spatial and nonspatial auditory tasks.

Slow event-related brain potentials were recorded from the human scalp during spatial and nonspatial auditory delayed matching-to-sample and n-back tasks to find out whether there are differences in the distribution of slow potentials during the retention of audiospatial and pitch information. The performance of both the location and pitch tasks produced slow potentials during the delay phase o...

The 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...

Serotonin regulates performance nonmonotonically in a spatial working memory network.

The prefrontal cortex (PFC) contains a dense network of serotonergic [serotonin, 5-hydroxytryptamine (5-HT)] axons, and endogenous 5-HT markedly modulates PFC neuronal function via several postsynaptic receptors. The therapeutic action of atypical antipsychotic drugs, acting mainly via 5-HT receptors, also suggests a role for serotonergic neurotransmission in cognitive functions. However, psych...
