Article Abstract
Studies have shown that there are overlapping neural bases for cognitive and affective conflict control, but whether the neural activity patterns caused by the two types of conflict are similar remains to be explored. The present study utilizes electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) to temporally and spatially analyze the differences between cognitive and affective conflict control. We employ a semantic conflict task which includes blocks of cognitive and affective judgements primed by conflicting and non-conflicting contexts. The results showed a typical neural conflict effect in the cognitive judgment blocks as reflected by greater amplitudes of P2, N400, and the late positive potential (LPP), as well as greater activation of the left pre-supplementary motor area (pre-SMA) and the right inferior frontal gyrus (IFG) in the conflict condition relative to the non-conflict condition. These patterns did not emerge in the affective judgments, but instead, showed reversed effects of the LPP and in the left SMA. Taken together, these findings suggest that cognitive and affective conflict control result in different neural activity patterns.

Background: Stroke is a leading cause of death and disability globally, with frequent cognitive sequelae affecting up to 60% of stroke survivors. Despite the high prevalence of post-stroke cognitive impairment (PSCI), early detection remains underemphasized in clinical practice, with limited focus on broader neuropsychological and affective symptoms. Stroke elevates dementia risk and may act as a trigger for progressive neurodegenerative diseases.

This study compared symptom reporting and cognitive test performance within 72 h of a suspected concussion between high school student-athletes with and without pre-injury self-reported mental health treatment. Eight hundred seventy-nine high school athletes with ( = 75) and without ( = 804) a self-reported history of treatment for anxiety or depression underwent preseason baseline testing, and post-injury testing within 72 h of suspected concussion. At baseline, adolescents with a self-reported history of treatment for anxiety or depression ( = 75, 8.

Purpose: Sleep is essential for effective daily cognitive and affective functioning, both of which are critical in the school context. In recent years, average nighttime sleep duration has been decreasing, particularly among teenagers, in parallel with an increase in screen time. Here, we aimed at assessing whether parental rules pertaining to the use of electronic devices in the evening were associated with enhanced sleep duration in healthy adolescents.

Background: Older adults are more vulnerable to severe consequences caused by seasonal influenza. Although seasonal influenza vaccination (SIV) is effective and free vaccines are available, the SIV uptake rate remained inadequate among people aged 65 years or older in Hong Kong, China. There was a lack of studies evaluating ChatGPT in promoting vaccination uptake among older adults.
