Summary: The present study found that pictures of oneself elicited a larger late positive potential (LPP) compared to pictures of strangers and objects. The LPP was related to self-reported appearance anxiety and symptoms of BDD. These findings suggest that the LPP may serve as a neural marker of appearance concerns.

Summary: This study aimed to investigate whether error monitoring increases in unpredictable contexts, and whether ERN is also increased. The results showed that ERN increased when participants evaluated their responses in unpredictable moments. Furthermore, EMG data revealed slower response times and fewer inhibitory errors in temporally unpredictable trials, indicating enhanced control of unwanted actions. Overall, this study demonstrated that temporal unpredictability increases the control of unwanted actions.

Summary: Mindfulness practice was found to increase prepulse facilitation in the study, using a prepulse inhibition/facilitation paradigm to investigate the effect on automatic attention regulation processes. The brief mindfulness exercise was shown to have an impact on startle response modulation, specifically increasing preparation for upcoming stimuli.

Summary: The defensive reaction to threats consists of non-specific physiological arousal and specific attentional prioritization. The low-road hypothesis suggests that these reactions are induced automatically and unconsciously. This study used ERPs to compare the engagement of attention in perceiving subliminal and supraliminal fearful facial expressions. The results showed that attentional selection only occurs when threatening stimuli are consciously perceived, challenging the low-road hypothesis.

Summary: This study assessed the hypothesis that neural markers of emotional and task stimulus significance can be demonstrated at the individual level. The findings showed that event-related components sensitive to emotional significance and explicit task demands reached statistical significance in the tests, demonstrating that these neural markers can be assessed at the individual level.

Summary: The preferential processing of self-related information is influenced by its high familiarity, but individuals may also show a preference for initially unfamiliar stimuli associated with themselves. This research aims to address the role of early attention in prioritizing newly acquired self-associated information and whether both familiar and new information referring to a subjectively significant person benefits from preferential attentional processing.

Summary: Despite focus on investor attention and positive jump returns, there is little research on Bitcoin's market reactions to information shocks. Results show abundant positive daily jump returns and reveal Bitcoin investors' underreaction to large shocks. Mechanism analysis suggests that investor attention reduces the underreaction magnitude.

Summary: The study confirms the anticipatory nature of the vN component in relation to preparatory visuospatial attention, showing that attention effects start before stimulus presentation. In the top-down attentional control process, the orientation of attention emerges before the selection of hands.

Summary: Evidence suggests reduced self-referential processing in individuals with autism spectrum disorder (ASD). Compared to typically developing individuals, those with ASD show similar attentional biases towards their own face and the face of a close-other, with impaired differentiation between self and others.

Summary: This study examines the impact of predictive capability on learning. The results demonstrate that the predictability of stimulus attributes affects the learning of other attributes, and that temporal unpredictability caused by random onsets reduces neurophysiological responses.

Summary: The study found differences in latency and amplitude of reward positivity (RewP) in 4- to 6-year-old children, with RewP latency decreasing and amplitude increasing with age. These findings suggest that both amplitude and latency of RewP may function as individual difference measures of reward processing in early childhood.

Summary: Reduced flanker P300 amplitude is associated with heightened depression and anxiety symptoms in adolescents, but uniquely related to depressive symptoms. This negative association between P300 and depression is more apparent in female adolescents.

Summary: In older adults, the severity of depressive symptoms is associated with reduced go and no-go P300 amplitudes, with the most unique variance accounted for by a reduced no-go P300 amplitude. Loneliness significantly moderates the relationship between no-go P300 and depressive symptom severity, indicating that there is no relationship between the two among older adults reporting low levels of loneliness.

Summary: This study examined the electrocortical measures of error monitoring in early adolescents with and without OCD, using a data-driven, cluster-based approach. The results showed that participants with OCD exhibited increased error-related negativity and error-related theta, as well as reduced error-related beta power compared to those without OCD. The findings suggest that pediatric OCD may be characterized by enhanced error monitoring and post-error inhibition.

Summary: Reduced cue-P300, RewP, and FN amplitudes were found to be associated with increased depressive symptoms in adolescents. This study provides valuable insights into the individual differences in reward processing among adolescents with increased depressive symptomatology, using the monetary incentive delay (MID) task.

Summary: A framework suggests that anxiety has two dimensions: anxious apprehension and anxious arousal, which have been linked to differential neural responses in previous research. This study investigated the association between trait worry, anxious arousal, and neural processing of anticipated threat. Results showed that worry was associated with increased responses to unpredictable threat and increased attention to threat-irrelevant stimuli during predictable threat anticipation. Anxious arousal was associated with increased responses to unpredictable threat anticipation. These findings highlight the importance of anxiety dimensions in understanding physiological responses to threat and support the notion that worry is associated with hypersensitivity to unpredictable aversive contexts.

Summary: Lower neural response to reward predicts subsequent depression during adolescence. Pubertal development and biological sex have important effects on reward system development and depression. Relations among these variables across the transition from childhood to adolescence are not well characterized.

Summary: A heightened sensitivity to unpredictable threat has been identified as a potential transdiagnostic mechanism of psychopathology, but most research has been conducted in adults. This study examined if psychophysiological indicators of sensitivity to unpredictable threat were comparable in youth during developmental periods associated with increased risk for psychopathology. The study also investigated whether sensitivity to unpredictable threat is correlated between parents and their offspring. Results showed that adolescents demonstrated greater defensive motivation and attentional engagement in anticipation of unpredictable threat compared to their parents, and there was correlation in overall startle potentiation between adolescents and parents. Sensitivity to threat might be a mechanism of vulnerability that is partially shared between parents and their offspring.

Summary: This study examined neurophysiological differences in adolescents with and without a history of preschool-onset depression (PO-MDD) using electroencephalography (EEG). The results showed that adolescents with a history of PO-MDD had smaller doors-P300 amplitude during cognitive exploration, while there were no group differences in reward feedback. Furthermore, smaller doors-P300 amplitude was associated with lower baseline income-to-needs ratio, older age, and female gender.

Summary: This study examined the impact of COVID-related worries on changes in anxiety symptoms among community dwelling older adults. It was found that COVID-related worries were associated with increased anxiety symptoms, but pre-COVID psychological resilience was associated with a decrease in anxiety symptoms. Furthermore, psychological resilience moderated the association, with greater increases in anxiety symptoms observed among individuals with low pre-COVID psychological resilience.
