Affective perception has been suggested to involve the coordinated activation of widely distributed cortical networks, including those involved in sensory storage/analysis and higher-order structures, such as the prefrontal cortex that regulate these processes. We measured regional electroencephalogram (EEG) activity while young adult participants viewed(More)
The capacity to associate neutral stimuli with affective value is an important survival strategy that can be accomplished by cell assemblies obeying Hebbian learning principles. In the neuroscience laboratory, classical fear conditioning has been extensively used as a model to study learning-related changes in neural structure and function. Here, we review(More)
Although previous studies have shown that socially anxious individuals exhibit greater relative right frontal electroencephalogram (EEG) activity at rest, no studies have investigated whether improvements in symptoms as a result of treatment are associated with concomitant changes in resting brain activity. Regional EEG activity was measured at rest in 23(More)
Coupling between EEG delta and beta oscillations is enhanced among anxious and healthy individuals during anticipatory anxiety. EEG coupling patterns associated with psychotherapy have not yet been quantified in socially anxious individuals. In this study, we used a double baseline, repeated measures design, in which 25 adults with a principal diagnosis of(More)
OBJECTIVE Recent studies have noted personality differences among adult survivors of very preterm birth, including higher neuroticism and cautiousness and lower extraversion. We attempted to replicate and extend these recent studies by examining personality characteristics across multiple components of personality that traditionally define personality(More)
When organisms confront unpleasant objects in their natural environments, they engage in behaviors that allow them to avoid aversive outcomes. Here, we linked visual processing of threat to its behavioral consequences by including a motor response that terminated exposure to an aversive event. Dense-array steady-state visual evoked potentials were recorded(More)
Increasing evidence suggests that cross-frequency spectral coupling between slow (SW) and fast (FW) wave activity in the EEG supports information exchange between separate and functionally distinct neural systems. Further, evidence suggests that states of uncertainty, anticipation and anxious apprehension involve a high degree of SW-FW coupling. We examined(More)
Spectral coupling between delta and beta oscillations has been related to anxiety. The authors provide preliminary evidence that frontal brain oscillatory coupling discriminates children born to socially phobic versus healthy parents, despite there being no difference in parental perceptions of their children's shyness.
Although the search for psychophysiological manifestations of social anxiety has a rich history, there appear to be no published reports examining the reliability of continuous electrocortical measures that putatively index stress vulnerability and stress reactivity in socially anxious individuals. We examined the 1-week test-retest reliability of regional(More)
Social fearfulness is expressed on a continuum of severity from moderate distress to incapacitating fear. The present article focuses on the brain states associated with this broad dimension of social anxiety in humans. In total, 70 published studies are summarized documenting the neural correlates of social anxiety during states of rest, threat-related(More)
