Emotional interference in enumeration: A working memory perspective
We investigated the influence of emotional stimuli on enumeration. On each trial a set of 1 to 10 affectively positive, negative or neutral words were presented for 200 ms each. Participants counted the words after each trial. Error was greater and response times were longer for negative and positive words than for neutral words. Most importantly, this effect was shown only for set sizes within...
متن کاملCausal evidence for frontal involvement in memory target maintenance by posterior brain areas during distracter interference of visual working memory.
Dorsolateral prefrontal cortex (DLPFC) is recruited during visual working memory (WM) when relevant information must be maintained in the presence of distracting information. The mechanism by which DLPFC might ensure successful maintenance of the contents of WM is, however, unclear; it might enhance neural maintenance of memory targets or suppress processing of distracters. To adjudicate betwee...
متن کاملPrefrontal inhibition of threat processing reduces working memory interference
Bottom-up processes can interrupt ongoing cognitive processing in order to adaptively respond to emotional stimuli of high potential significance, such as those that threaten wellbeing. However it is vital that this interference can be modulated in certain contexts to focus on current tasks. Deficits in the ability to maintain the appropriate balance between cognitive and emotional demands can ...
متن کاملAn unpleasant emotional state reduces working memory capacity: electrophysiological evidence
Emotional states can guide the actions and decisions we make in our everyday life through their influence on cognitive processes such as working memory (WM). We investigated the long-lasting interference that an unpleasant emotional state had on goal-relevant WM representations from an electrophysiological perspective. Participants performed a change detection task that was preceded by the pres...
متن کاملThe neural bases of distracter-resistant working memory.
A major difference between humans and other animals is our capacity to maintain information in working memory (WM) while performing secondary tasks, which enables sustained, complex cognition. A common assumption is that the lateral prefrontal cortex (PFC) is critical for WM performance in the presence of distracters, but direct evidence is scarce. We assessed the relationship between fMRI acti...
