Summary: People often struggle to distinguish between internal and external knowledge when using the internet for information, leading to overconfidence in their ability to access external information and in their own cognitive abilities. The swift and seamless interface of online search may contribute to this misattribution, causing individuals to mistake internet knowledge for their own.

Summary: The cultural and geographical properties of the environment have a significant impact on cognition and mental health. Living near green spaces is beneficial, while urban residence is associated with a higher risk of some psychiatric disorders. Growing up outside cities influences non-verbal spatial navigation ability, with better performance observed in individuals who grew up in environments similar to the ones they navigated.

Summary: Within memory research, destination memory, which refers to the ability to remember to whom information was previously told, is closely linked to social cognition. This review provides a comprehensive overview of destination memory research and highlights its involvement in social interaction. It examines various factors that influence destination memory, including recipient-related factors (e.g., familiarity, emotional states, and distinctiveness/attractiveness) and sender-related factors (e.g., sender's extroversion) in social communication. The review suggests that destination memory requires the sender to infer the cognitive and affective state of the recipient and attribute the output message to a recipient-related stereotype. Extrovert senders may have an advantage in destination memory due to their preference for social communication and processing of social information. The review also emphasizes the importance of recipient features such as familiarity, age, emotional state, distinctiveness, and attractiveness. By providing a comprehensive framework, this review demonstrates the significance of destination memory in communicative efficacy and social interactions.

Summary: This systematic review explores the association between daytime napping and cognitive function in older adults. Observational studies suggest a U-shaped relationship between napping duration and cognitive function, with moderate napping benefiting cognitive health compared to no napping or long napping. Intervention studies indicate that a single session of afternoon napping may improve psychomotor function and working memory, but more research is needed on the effects of multiple napping sessions.

Summary: Considerable evidence supports the importance of specific nutrients for brain development. This study proposes the existence of different vital nutrients for the aging brain due to aging's distinct pathophysiology, which causes cognitive aging. By isolating brain regions and pathways linked to either cognitive aging or late-life diseases, researchers have identified nutrients relevant to cognitive aging. A research program on flavanols has illustrated the benefits of dietary bioactives on the brain, aiming to generate dietary recommendations for cognitive fortification in the elderly.

Summary: A systematic review and meta-analysis found that acute ingestion of Guarana has a small positive effect on human cognitive performance, improving response time but not accuracy. Whether the changes in cognitive performance are related to the caffeine content or other bioactive substances in Guarana remains unknown and requires further research.

Summary: Cognitive inhibition, specifically the ability to inhibit irrelevant information from memory, is impaired with aging. This study used three computer-based tasks to assess memory inhibition and identified distinct memory retrieval and memory inhibition processes that were age-dependent. The findings suggest that inhibitory impairments may precede memory deficits in healthy aging.

Summary: Memory impairment is common in patients after symptomatic stroke and is strongly associated with the risk of poststroke dementia. This review discusses the natural history of memory impairment after stroke, including factors influencing its trajectory. It also explores the pathophysiology of memory impairment, as well as methods for measuring deficits and potential therapeutic approaches. The review highlights gaps in knowledge, particularly regarding long-term memory trajectory and the use of advanced neuroimaging and biomarkers to better understand the underlying mechanisms.

Summary: The studies demonstrate that direct social evaluation of multitasking is a more potent stressor compared to multitasking with indirect evaluation. Additionally, anticipation of socially evaluated multitasking leads to increased anxiety, tension, and worry, supporting the idea that threat anticipation may prolong the activation of stress mechanisms. The period of anticipation of stressful events may be critical to understanding the process of stress regulation, and further investigation into these processes is recommended.

Summary: Previous studies on error processing have primarily focused on the posterior medial frontal cortex, but the role of other brain regions has been underestimated. This study used activation likelihood estimation meta-analyses to explore brain activity related to committing errors and responding successfully in interference tasks. It was found that the salience network and the temporoparietal junction were commonly involved in both correct and incorrect responses, indicating their general involvement in coping with situations that require increased cognitive control. Error-specific convergence was observed in the dorsal posterior cingulate cortex, posterior thalamus, and left superior frontal gyrus, while successful responding showed stronger convergence in the dorsal attention network and lateral prefrontal regions. Underrecruitment of these regions in error trials may reflect failures in activating the appropriate stimulus-response contingencies necessary for successful response execution.
