AI Article Synopsis
- The study investigates the link between self-reported sleep and cognitive function using a large dataset of 1,054 participants, employing specification curve analysis (SCA) for a comprehensive evaluation.
- Results indicate that poorer self-reported sleep correlates with worse cognitive performance, but the strength of this relationship varies across different aspects of cognitive function.
- Key findings highlight that daytime dysfunction significantly impacts subjective cognitive function, while sleep duration and efficiency are more closely related to objective cognitive measures, suggesting that the relationship between sleep and cognition is complex and context-dependent.
Article Abstract
The relationship between self-reported sleep and cognitive function is complex; it is unclear whether self-reported sleep is a robust correlate of people's cognitive function. We address this gap by using a comprehensive large-scale dataset (N = 1054) coupled with a novel modeling approach, specification curve analysis (SCA), to test the association between self-reported sleep and cognitive function. The results of the SCA showed robust correlations between self-reported sleep and cognitive function, with poorer sleep associated with worse cognitive function. Furthermore, the correlations between sleep components and cognitive function were heterogeneous, with differences emerging across cognitive measures and domains. Specifically, daytime dysfunction was associated with the strongest effect on subjective cognitive function, whereas sleep duration and sleep efficiency had the strongest effect on objective cognitive function. Therefore, the relationship between self-reported sleep and cognition depends largely on what and how cognitive function is measured. Our findings guide measurement and domain selection for future research on the role of sleep in cognitive function.

The twenty-first century has brought forth a deluge of theories and data shedding light on the neural mechanisms of motivated behavior. Much of this progress has focused on dopaminergic dynamics, including their signaling properties (how do they vary with expectations and outcomes?) and their downstream impacts in target regions (how do they affect learning and behavior?). In parallel, the basal ganglia have been elevated from their original implication in motoric function to a canonical circuit facilitating the initiation, invigoration, and selection of actions across levels of abstraction, from motor to cognitive operations.

Background: Health inequalities among older adults become increasingly pronounced as aging progresses. In the digital era, some researchers argue that access to and use of digital technologies may contribute to or exacerbate these existing health inequalities. Conversely, other researchers believe that digital technologies can help mitigate these disparities.

Background And Objectives: Previous studies have shown inconsistent associations between red meat intake and cognitive health. Our objective was to examine the association between red meat intake and multiple cognitive outcomes.
Methods: In this prospective cohort study, we included participants free of dementia at baseline from 2 nationwide cohort studies in the United States: the Nurses' Health Study (NHS) and the Health Professionals Follow-Up Study (HPFS).
Empathy is an aspect of social cognition which has gained much attention to explain sexual violence perpetration, with research resulting in mixed and contradictory findings. Another aspect of social cognition, which has been linked to, and even used synonymously with, cognitive empathy is Theory of Mind (ToM). However, research is severely lacking on the role which ToM may play in sexual violence.
