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 ...
Action video game playing is associated with improved visual sensitivity, but not alterations in visual sensory memory.
(Atten Percept Psychophys, 2013-08)
Action video game playing has been experimentally linked to a number of perceptual
and cognitive improvements. These benefits are captured through a wide range of psychometric
tasks and have led to the proposition that action ...
The neural dynamics of stimulus and response conflict processing as a function of response complexity and task demands.
(Neuropsychologia, 2016-04)
Both stimulus and response conflict can disrupt behavior by slowing response times
and decreasing accuracy. Although several neural activations have been associated
with conflict processing, it is unclear how specific any ...
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 ...
The role of stimulus salience and attentional capture across the neural hierarchy in a stop-signal task.
(PLoS One, 2011)
Inhibitory motor control is a core function of cognitive control. Evidence from diverse
experimental approaches has linked this function to a mostly right-lateralized network
of cortical and subcortical areas, wherein a ...
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 ...
The influence of different Stop-signal response time estimation procedures on behavior-behavior and brain-behavior correlations.
(Behav Brain Res, 2012-04-01)
The fundamental cognitive-control function of inhibitory control over motor behavior
has been extensively investigated using the Stop-signal task. The critical behavioral
parameter describing stopping efficacy is the Stop-signal ...
Cross-modal stimulus conflict: the behavioral effects of stimulus input timing in a visual-auditory Stroop task.
(PLoS One, 2013)
Cross-modal processing depends strongly on the compatibility between different sensory
inputs, the relative timing of their arrival to brain processing components, and on
how attention is allocated. In this behavioral study, ...
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 ...
