Neural Mechanisms of Interference Control in Working Memory: Effects of Interference Expectancy and Fluid Intelligence
BACKGROUND A critical aspect of executive control is the ability to limit the adverse effects of interference. Previous studies have shown activation of left ventrolateral prefrontal cortex after the onset of interference, suggesting that interference may be resolved in a reactive manner. However, we suggest that interference control may also operate in a proactive manner to prevent effects of ...
متن کاملWorking Memory Capacity Affects the Interference Control Of
1 It is important to understand the role of individual differences in working memory capacity 2 (WMC). We investigated the relation between differences in WMC and N1 in event-related 3 brain potentials as a measure of early selective attention for an auditory distractor in 4 three-stimulus oddball tasks that required minimum memory. A high-WMC group (n = 13) 5 showed a smaller N1 in response to...
متن کاملDissociable brain mechanisms for inhibitory control: effects of interference content and working memory capacity.
In this study, event-related fMRI was used to examine whether the resolution of interference arising from two different information contents activates the same or different neuronal circuitries. In addition, we examined the extent to which these inhibitory control mechanisms are modulated by individual differences in working memory capacity. Two groups of participants with high and low working ...
متن کاملMechanisms of Interference in Vibrotactile Working Memory
In previous studies of interference in vibrotactile working memory, subjects were presented with an interfering distractor stimulus during the delay period between the target and probe stimuli in a delayed match-to-sample task. The accuracy of same/different decisions indicated feature overwriting was the mechanism of interference. However, the distractor was presented late in the delay period,...
متن کاملSynaptic mechanisms of interference in working memory
Information from preceding trials of cognitive tasks can bias performance in the current trial, a phenomenon referred to as interference. Subjects performing visual working memory tasks exhibit interference in their trial-to-trial response correlations: the recalled target location in the current trial is biased in the direction of the target presented on the previous trial. We present modeling...
