Summary: This study aimed to investigate the relationship between subjective sleep measures and cognitive function. The results showed a U-shaped association between sleep duration and cognitive decline, and insomnia symptoms were associated with memory decline. Older men were at a higher risk of cognitive decline related to sleep factors compared to women and younger men.

Summary: Male vulturine guineafowl strategically exhibit higher-cost aggressive interactions toward individuals with lower ranks, while lower-cost aggressive interactions are directed toward individuals further down the hierarchy. These results support the hypothesis that the costs associated with different interaction types can determine their expression in social groups with steep dominance hierarchies.

Summary: The study suggests that socio-spatial behavior can be seen as a series of excursions originating and ending in close proximity to another individual. By measuring the social distance between two individuals, different types of social excursions can be distinguished. Research on rodents shows that each group displays a prevalent excursion type reflecting distinct social dynamics.

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: The global increase in lifespan is expected to lead to a rise in cognitive impairment, prompting a shift towards natural products like curcumin for potential treatment. Despite promising preclinical studies, challenges such as low bioavailability and rapid metabolism have hindered curcumin's clinical efficacy, prompting the need for new strategies to improve its use.

Summary: This study investigates and compares the effects of late-life labour market participation on cognitive functioning in South Korea and USA. The results show that entering the labour market benefits cognitive functioning in South Korea but not in the USA, while exiting the late-life labour market leads to cognitive decline in both countries. The findings suggest that participant characteristics and reasons for labour market participation may contribute to the differential effects.

Summary: Research has shown that the functional connectivity between brain regions is modulated by social context, with different social interactions resulting in significant changes in fronto-temporal connectivity. Viewing aggressive behavior leads to a limited increase in temporo-temporal and a weak increase in cingulate-temporal connectivity, while interactions with uncertain outcomes are associated with a pronounced increase in temporo-temporal and cingulate-temporal functional connectivity.

Summary: Maintaining executive functions is crucial for autonomy and daily activities. This study examined changes in executive function over a 3-year period using data from the Canadian Longitudinal Study on Aging (CLSA). Social determinants, such as social positioning, social support, and education, were not significantly associated with changes in executive function, suggesting that they may be related to initial differences in cognitive functioning rather than rapid cognitive aging.

Summary: This study examined the role of social network types in moderating the impacts of having a child with a developmental disability on parents' health. The results showed that parents of children with developmental disabilities were more likely to have restricted/unsupported networks, while parents in the comparison group were more likely to have diverse/supported networks. Social support was more important for differentiating the network types of parents with developmental disabilities, while social integration was more salient for the comparison group. Parents of children with developmental disabilities had worse physical and mental health outcomes compared to parents of children without disabilities. However, the diverse/supported network type had a compensatory effect and conferred greater mental health benefits to parents of children with developmental disabilities. The diverse/supported network type was also associated with better physical health, with no differences between the two parent groups.

Summary: Comparing two independent studies of older adults, it was found that there is no evidence to suggest that today's older adults have more positive views on aging than older adults did two decades ago. The subjective views on aging have not improved over time, and there is a possibility that individual age views have become increasingly decoupled from societal age views.

Summary: The stress systems play a crucial role in mediating the physiological responses to stress in animals. While the individual-level effects of stress on behavior and performance have been well studied, it remains largely unknown how stressed individuals can influence the stress systems of other group members and subsequently affect collective behavior. This article proposes that understanding the extent to which stress transmission modulates animal collectives is an important research avenue.

Summary: In this study, the impact of a probiotic product containing different strains of probiotics on stress processing was investigated. The results showed that probiotic intervention subtly altered brain activity and functional connectivity in specific brain regions and had a greater effect on the initial stress response. These findings support the potential of probiotics as a non-pharmaceutical treatment modality for stress-related disorders.

Summary: Emodiversity, the variety and abundance of emotions experienced, plays a significant role in mental and physical health outcomes. Greater positive emodiversity is associated with fewer symptoms of depression, anxiety, and physical health issues. However, greater negative emodiversity is linked to more symptoms of depression, anxiety, and physical health problems.

Summary: The study focused on the effects of an online version of the Trier Social Stress Test (TSST) on cortisol, alpha amylase, pleasure, and arousal levels in adults. It also compared the cortisol responses between men and women. The results showed that the online TSST successfully induced psychophysiological stress in adults, with significant increases in cortisol, alpha amylase, and arousal levels, and a decrease in pleasure. Moreover, cortisol responses were found to be stronger in males compared to females.

Summary: Growing evidence suggests that natural environments contribute to psychological health and physiological relaxation. This study investigates the effects of nature-based relaxation videos on heart rate variability (HRV) and heart rate (HR), revealing a decrease in HR and an increase in HRV during video interventions. The findings suggest that aspects of early life adversity and trait mindfulness may influence individual responses to relaxation videos.
