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 ...
A pilot randomized controlled trial with paroxetine for subthreshold PTSD in Operation Enduring Freedom/Operation Iraqi Freedom era veterans.
(Psychiatry Res, 2013-04-30)
Subthreshold posttraumatic stress disorder (PTSD) is associated with increased risk
for suicidality, depression, and functional impairment. We thus conducted a small
(N=12) pilot randomized controlled trial (RCT) with paroxetine ...
Randomized controlled trial of universal postnatal nurse home visiting: impact on emergency care.
(Pediatrics, 2013-11)
BACKGROUND AND OBJECTIVES: Although nurse home visiting has proven efficacious with
small samples, scaling up to community populations with diverse families has not yet
proven effective. The Durham Connects program was developed ...
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, ...
Looking at the ventriloquist: visual outcome of eye movements calibrates sound localization.
(PloS one, 2013-01)
A general problem in learning is how the brain determines what lesson to learn (and
what lessons not to learn). For example, sound localization is a behavior that is
partially learned with the aid of vision. This process ...
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 ...
Direct and indirect reputation formation in nonhuman great apes (Pan paniscus, Pan troglodytes, Gorilla gorilla, Pongo pygmaeus) and human children (Homo sapiens).
(J Comp Psychol, 2013-02)
Humans make decisions about when and with whom to cooperate based on their reputations.
People either learn about others by direct interaction or by observing third-party
interactions or gossip. An important question is ...
The impact of the developmental timing of trauma exposure on PTSD symptoms and psychosocial functioning among older adults.
(Dev Psychol, 2013-11)
The present study examined the impact of the developmental timing of trauma exposure
on posttraumatic stress disorder (PTSD) symptoms and psychosocial functioning in a
large sample of community-dwelling older adults (N = ...
A functional polymorphism in the 5HTR2C gene associated with stress responses also predicts incident cardiovascular events.
(PLoS One, 2013)
Previously we have shown that a functional nonsynonymous single nucleotide polymorphism
(rs6318) of the 5HTR2C gene located on the X-chromosome is associated with hypothalamic-pituitary-adrenal
axis response to a stress ...
