Abstract Background Based on facial expression experiments, childhood adversity may be associated with threat-related information processing bias. Yet, it is unclear whether this generalizes to other stimuli, such as social and non-social visual scenes. Methods We combined fast periodic stimulation frequency-tagging electroencephalography (EEG) eye-tracking assess automatic implicit neural discrimination, salience preferential looking towards negative versus neutral scenes in young adults...
Abstract Background and Hypothesis Childhood adversity is associated with a myriad of psychiatric symptoms, including psychotic experiences (PEs), multiple psychological processes that may all mediate these associations. Study Design Using network approach, the present study examined complex interactions between childhood adversity, PEs, other mediators (ie, activity-related social stress, negative affect, loneliness, threat anticipation, maladaptive cognitive emotion regulation, attachment...
BACKGROUND: Studies linking childhood adversity with risk for psychopathology suggest a threat-related information processing bias in those exposed. METHODS: We combined frequency-tagging electroencephalography (EEG) and eye-tracking to assess automatic implicit facial expression young adults aged 16–24 years emerging psychiatric symptoms history of (N = 52) as compared healthy controls 61). Neural discrimination angry or happy faces from neutral was assessed via an EEG oddball paradigm....
Uncertainty contributes to stress and anxiety-like behaviors by impairing the ability of participants objectively estimate threat. Our study used cue-picture paradigm in conjunction with event-related potential (ERP) technique explore temporal dynamics anticipation for response uncertain threat healthy individuals. This task two types cue. While 'certain' cues precisely forecasted valence subsequent pictures (negative or neutral), following 'uncertain' was not predictable. ERP data showed...
Abstract Uncertainty of threat has been linked to anxiety, but little is known about how neurophysiological responses change as uncertain threats approach and whether trait anxiety modulates these changes. The current study was designed explore aspects the dynamics defensive motivation (startle reflex elicited by acoustic startle probes), attention (probe N100 component event‐related potentials autonomic nervous system activity (heart rate) when approaching certain or in a variant...
Childhood adversity has been associated with alterations in threat-related information processing, including heightened perceptual sensitivity and attention bias towards threatening facial expressions, as well hostile attributions of neutral faces, although there is a large degree variability inconsistency reported findings. Here, we aimed to implicitly measure neural expression processing 120 adolescents between 12 16 years old (M = 13.93) without exposure childhood adversity. We combined...
Background: Fear learning and generalization is one of the postulated transdiagnostic processes linking childhood adversity to psychopathology. Methods: Twenty-seven adversity-exposed individuals with (sub-)clinical psychiatric symptoms across at least two symptom dimensions (depressive, anxiety psychotic symptoms) 30 healthy controls, aged 17-24 years old, underwent a fear paradigm. Risk ratings reaction times were measured indicate responses.Results: During acquisition, reduced...
Abstract Exercise has been widely recognized for its benefits on cognitive health. One potential underlying mechanism is the modulation of hippocampal pattern separation (PS), a memory process crucial accurate storage and preventing interference. PS can be gauged behaviorally with mnemonic discrimination task using images, neurally functional magnetic resonance imaging assessing activation primarily dentate gyrus CA3 subregions. While number studies have demonstrated positive effect acute...
Acute exercise has been associated with cognitive improvements, particularly in memory processes linked to the hippocampus, such as ability discriminate between similar stimuli, called hippocampal pattern separation. This can be assessed behaviorally a mnemonic discrimination task and neurally functional magnetic resonance imaging (fMRI). Additionally, previous research shown an emotional modulatory effect on separation, involving amygdala. In this randomized between-subject study, we...
The social salience hypothesis proposes that the neuropeptide oxytocin (OT) can impact human behavior by modulating of cues. Here, frequency-tagging EEG was used to quantify neural responses versus non-social stimuli while administering a single dose OT (24 IU) placebo treatment. Specifically, two streams faces and houses were superimposed on one another, with each stream tagged particular presentation rate (i.e., 6 7.5 Hz or vice versa). These distinctive frequency tags allowed...
Anxiety and depression have been shown to negatively influence the processing of emotional information in working memory. However, most studies examined anxiety-related or depression-related memory deficits independently, without considering their high co-morbidity. We tested effects valence on performance among healthy young adults with varying levels anxiety depressive symptoms. Ninety aged between 18–24 (51 female) completed an 2-back task which positive, negative, neutral images were...
The anticipation of oncoming threats is emotionally challenging and related to anxiety. current study aimed investigate the neural regulatory processes during anticipatory preparations in stressful situations relation trait anxiety, especially an uncertainty-related situation. To this end, we measured within-subject delta-beta amplitude-amplitude correlation (AAC) phase-amplitude coupling (PAC) with electroencephalography using a well-defined stress-inducing paradigm 28 high-trait-anxiety...
