Cool executive dysfunction is a crucial feature in people living with schizophrenia which is related to cognition impairment and the severity of the clinical symptoms. Based on electroencephalogram (EEG), our current study explored the change of brain network under the cool executive tasks in individuals living with schizophrenia before and after atypical antipsychotic treatment (before_TR vs. after_TR). 21 patients with schizophrenia and 24 healthy controls completed the cool executive tasks, involving the Tower of Hanoi Task (THT) and Trail-Marking Test A-B (TMT A-B). The results of this study uncovered that the reaction time of the after_TR group was much shorter than that of the before_TR group in the TMT-A and TMT-B. And the after_TR group showed fewer error numbers in the TMT-B than those of the before_TR group. Concerning the functional network, stronger DMN-like linkages were found in the before_TR group compared to the control group. Finally, we adopted a multiple linear regression model based on the change network properties to predict the patient's PANSS change ratio. Together, the findings deepened our understanding of cool executive function in individuals living with schizophrenia and might provide physiological information to reliably predict the clinical efficacy of schizophrenia after atypical antipsychotic treatment.

Although individual differences in children's moral self-concept emerge during early childhood and predict future behavioral outcomes, the cognitive skills underlying the development of the moral self have received little attention. We addressed this gap with a longitudinal sample of 106 children (M = 52.78 months, SD = 6.

: The early identification of executive function (EF) delays should involve parental reports on children's executive control in daily activities, capturing both "hot" and "cool" executive functions. This study aimed to revalidate the reliability and validity of the Executive Functions and Occupational Routines Scale (EFORTS) and examine whether it represents both hot and cool EFs : Parents of 971 children (469 boys) aged 3 to 11 years (M = 6.08, SD = 1.

Background: Multiple sclerosis (MS) is an immune-mediated inflammatory disease that primarily targets the myelin of axons. Extremities are frequently affected, resulting in a negative impact on both activities of daily living (ADL) and quality of life. In recent years, there has been increasing interest in the potential benefits of exercise and blood flow restriction training (BFRT) programs as a therapeutic tool in people with neurological disorders.

Article Synopsis
- Short-term heat acclimation (HA) for trained athletes boosts sweating adaptations and thermal resilience, but prolonged HA is better for benefits in cooler conditions and red blood cell production.
- In a study with 20 elite cyclists, those undergoing 5 weeks of HA saw significant improvements in exhaustion time, sweat rates, and reduced sodium concentration after intense heat exposure.
- However, these benefits diminished quickly after a 2-week break from HA, indicating that while short-term acclimation is effective, the endurance gains may not last long without continued practice.
Comparison of Cold and Cool Cognition in Children With and Without Attention Deficit-Hyperactivity Disorder (ADHD).

Children with ADHD suffer from impaired attentional, executive, and emotional processing. This study aimed to compare attentional and executive processing using (non)emotional stimuli in children with and without ADHD. Eighty-five children with ADHD and 72 matched typically developing children performed the Stroop, continuous performance, and Go/No-Go tasks using (non)emotional stimuli.
