Emotional pictures elicit enhanced parietal positivities beginning around 300 ms following stimulus presentation. The magnitude of these responses, however, depends on both intrinsic (stimulus-driven) and extrinsic (context-driven) factors. In the present study, event-related potentials were recorded while participants viewed unpleasant neutral that described either more neutrally or negatively prior to presentation; temporospatial principal components analysis identified early late...
Threatening stimuli have been shown to preferentially capture attention using a range of tasks and measures. However, attentional bias threat has not typically found in unselected individuals behavioral measures the dot-probe task, one most common ways examining threat. The present study leveraged event-related potentials (ERPs) conjunction with task examine whether more direct might reveal an individuals. As previous studies, we no evidence reaction time; additionally, this measure...
There is growing awareness across the neuroscience community that replicability of findings about relationship between brain activity and cognitive phenomena can be improved by conducting studies with high statistical power adhere to well-defined standardised analysis pipelines. Inspired recent efforts from psychological sciences, desire examine some foundational using electroencephalography (EEG), we have launched #EEGManyLabs, a large-scale international collaborative replication effort....
Neural activity is increasingly used in addition to behavioral measures study anxiety and attentional biases toward threatening stimuli. Event-related potentials (ERPs) might be particularly useful because of their excellent temporal resolution. In particular, the late positive potential (LPP) reflects increased attention emotional stimuli-and was recently found larger with increasing state anxiety. This sought examine LPP among individuals generalized disorder (GAD).Fifteen GAD 15 healthy...
To examine whether reappraisal modifies responses to subsequent encounters with stimuli, participants viewed neutral and unpleasant pictures that were preceded by negative or descriptions which served as frames. A half an hour later, the same presented, without preceding frames; EEG was recorded rated each picture on arousal valence. In line previous work, compared elicited more positive early- (359 ms), mid- (1074 ms) late-latency (2436 centrally-distributed ERP components. Pictures...
Background Collectively, functional neuroimaging studies implicate frontal–limbic dysfunction in the pathophysiology of posttraumatic stress disorder (PTSD), as reflected by altered amygdala reactivity and deficient prefrontal responses. These neural patterns are often elicited social signals threat (fearful/angry faces) traumatic reminders (combat sounds, script-driven imagery). Although PTSD can be conceptualized a emotion dysregulation, few to date have directly investigated correlates...
Functional magnetic resonance imaging (fMRI) resting-state studies show generalized social anxiety disorder (gSAD) is associated with disturbances in networks involved emotion regulation, processing, and perceptual functions, suggesting a network framework integral to elucidating the pathophysiology of gSAD. However, fMRI does not measure fast dynamic interconnections functional networks. Therefore, we examined whole-brain connectomics electroencephalogram (EEG) during resting-state....
Abstract Intolerance of uncertainty (IU) is a transdiagnostic risk factor for internalizing disorders. Prior work has found that IU may be associated with either increased reactivity to threat or, alternatively, decreased differential responding between and nonthreat/safety cues (i.e., generalization). For example, by Morriss, Macdonald, & van Reekum (2016) higher was generalization during acquisition (using skin conductance response (SCR)), as well less differentiation extinction...
Psychological assessments typically rely on self-report and behavioral measures. Augmenting these with neurophysiological measures of the construct in question may increase accuracy predictive power assessments. Moreover, thinking about from an assessment perspective facilitate under-utilized research approaches (e.g., brain-based recruitment participants). However, lack normative data for most has prevented comparison individual responses to general population, precluding approaches. The...
Generalized anxiety disorder (GAD) may be characterized by emotion regulation deficits attributable to an imbalance between top-down (i.e., goal-driven) and bottom-up stimulus-driven) attention. In prior work, these attentional processes were examined presenting unpleasant neutral pictures within a working memory paradigm. The late positive potential (LPP) measured attention toward task-irrelevant pictures. Results from this work showed that load reduced the LPP across participants; however,...
