Neural mechanisms of context effects on face recognition: automatic binding and context shift decrements.
(J Cogn Neurosci, 2010-11)
Although people do not normally try to remember associations between faces and physical
contexts, these associations are established automatically, as indicated by the difficulty
of recognizing familiar faces in different ...
The architecture of cross-hemispheric communication in the aging brain: linking behavior to functional and structural connectivity.
(Cereb Cortex, 2012-01)
Contralateral recruitment remains a controversial phenomenon in both the clinical
and normative populations. To investigate the neural correlates of this phenomenon,
we explored the tendency for older adults to recruit prefrontal ...
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 ...
Adult age differences in functional connectivity during executive control.
(Neuroimage, 2010-08-15)
Task switching requires executive control processes that undergo age-related decline.
Previous neuroimaging studies have identified age-related differences in brain activation
associated with global switching effects (dual-task ...
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 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 ...
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 ...
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 ...
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 ...
