The dynamics of proactive and reactive cognitive control processes in the human brain.
(J Cogn Neurosci, 2014-05)
In this study, we leveraged the high temporal resolution of EEG to examine the neural mechanisms underlying the flexible regulation of cognitive control that unfolds over different timescales. We measured behavioral and ...
Rapid modulation of sensory processing induced by stimulus conflict.
(J Cogn Neurosci, 2011-09)
Humans are constantly confronted with environmental stimuli that conflict with task goals and can interfere with successful behavior. Prevailing theories propose the existence of cognitive control mechanisms that can suppress ...
Improvement in visual search with practice: mapping learning-related changes in neurocognitive stages of processing.
(J Neurosci, 2015-04-01)
Practice can improve performance on visual search tasks; the neural mechanisms underlying such improvements, however, are not clear. Response time typically shortens with practice, but which components of the stimulus-response ...
Cortical Brain Activity Reflecting Attentional Biasing Toward Reward-Predicting Cues Covaries with Economic Decision-Making Performance.
(Cereb Cortex, 2016-01)
Adaptive choice behavior depends critically on identifying and learning from outcome-predicting cues. We hypothesized that attention may be preferentially directed toward certain outcome-predicting cues. We studied this ...
Rapid brain responses independently predict gain maximization and loss minimization during economic decision making.
(J Neurosci, 2013-04-17)
Success in many decision-making scenarios depends on the ability to maximize gains and minimize losses. Even if an agent knows which cues lead to gains and which lead to losses, that agent could still make choices yielding ...
Reward associations reduce behavioral interference by changing the temporal dynamics of conflict processing.
(PLoS One, 2013)
Associating stimuli with the prospect of reward typically facilitates responses to those stimuli due to an enhancement of attentional and cognitive-control processes. Such reward-induced facilitation might be especially ...
