Article Synopsis
  • Decentralized clinical trials (DCTs) are designed to improve trial participation by moving activities closer to participants, but understanding what motivates people to join these trials, especially those with type 2 diabetes, is still unclear.
  • Focus groups in the Netherlands, Germany, and Austria with participants aged around 66 identified seven key themes about trial participation, including location, time, interaction with healthcare professionals, and technology use, revealing a total of 20 different motivating factors.
  • The most significant motivators for DCT participation were flexibility in location and time; however, factors like digital infrastructure and personal interaction were seen as both helpful and challenging, suggesting future DCT designs could benefit from addressing these barriers directly.

Article Synopsis
  • Humans and many animals tend to make relative quantity judgments consistently, but can also fall for quantity-related illusions, with the connectedness illusion being one example in humans.
  • This illusion causes people to underestimate the number of connected items compared to unconnected ones.
  • A study tested rhesus and capuchin monkeys to see if they experienced the same illusion, but the results showed that the monkeys actually preferred arrays of connected items as more numerous, indicating they do not experience the illusion as humans do.

Article Synopsis
  • This study examined the link between plasma biomarkers indicating endothelial dysfunction and cognitive performance in a sample of 9,414 older adults from the Netherlands, aged 57 to 93 years.
  • Researchers created a composite score from three specific biomarkers and assessed various cognitive functions like executive function and memory.
  • Results indicated a small, consistent association between higher endothelial dysfunction scores and poorer cognitive performance, but no evidence suggested that these markers influenced cognitive decline over time.

This article discusses the ephemeral reward task and how it is not always a clear and concise choice. This is demonstrated through some animal studies involving birds and primates. This article also shows that when compared to human studies, that there are positive correlations between the BART and optimal choice in the ephemeral reward task, meaning that those who took more risks also were more inclined to be optimal.

Maze studies have provided substantial information about nonhuman cognition, such as insights on navigational strategies, spatial memory, and choice discriminations. This knowledge can aid in how we understand the foraging strategies of many animals, particularly understudied and endangered species, such as the Guatemalan beaded lizard (). These actively foraging lizards rely on chemoreception to locate prey, but it is unknown to what extent they engage in olfaction and vomerolfaction to hunt and navigate their environment.

  • The study investigated how age, education, and sex/gender relate to performance in semantic fluency, which is the ability to generate words within a certain category.
  • Data from 2,391 individuals across three different cohorts were analyzed, measuring factors like average cluster size and lexical decision response time in addition to the total number of words generated.
  • Results indicated that older age and being female were both linked to lower performance in word generation, while higher education correlated with better performance across various metrics, showing consistent trends across different cohorts.

Among the many important empirical and theoretical contributions in her career Clayton and her colleagues advanced the idea that comparative cognition researchers would benefit from considering the role of magic and the techniques of the magician in some areas of cross-species cognitive study. They provided compelling and exciting studies using the techniques of the magician and demonstrated how those affect nonhuman animals that rely on vision, showing that there are similarities and dissimilarities in how susceptible some nonhuman species are to the magician's effects that typically work so well on human observers.

Background: Establishing collaborations between cohort studies has been fundamental for progress in health research. However, such collaborations are hampered by heterogeneous data representations across cohorts and legal constraints to data sharing. The first arises from a lack of consensus in standards of data collection and representation across cohort studies and is usually tackled by applying data harmonization processes.

The ability to quickly perceive and interpret threatening facial expressions from others is critical for successfully maintaining group cohesion in social nonhuman primate species. Rapid detection of threatening or negative stimuli in the environment compared to neutral stimuli, referred to as an attentional bias toward threat, is adaptive in that faster threat detection can lead to greater survival outcomes. However, the evolutionary roots of attentional bias formation toward social threat are not well understood.

Engaging executive functions provides an individual with the means to engage in cognitive control by adjusting to the environment and processing information in a way that leads to optimal outcomes. There are some claims that explicit training on certain executive functioning abilities provides benefits beyond the training tasks, but other studies indicate that this may not be true or may be limited based on age and other factors. This same mixed pattern has been reported with nonhuman species, where training or even experience in one specific area, like inhibition, sometimes leads to positive transfer in new but similar tasks that presumably also require executive functions.

Mazes have been used in many forms to provide compelling results showcasing nonhuman animals' capacities for spatial navigation, planning, and numerical competence. The current study presented computerized two-arm mazes to four rhesus macaques. Using these mazes, we assessed whether the monkeys could maximize rewards by overcoming mild delays in gratification and sum the values of Arabic numerals.

Delay of gratification and inhibitory control are generally considered measures of self-control. In humans, individual differences in measures of self-control are associated with a host of behavioral, neurological, cognitive, and health-related outcomes. Self-control is not unique to humans and has been demonstrated in a variety of nonhuman species using a variety of paradigms.

Cartilage defects alter natural function of articular cartilage and can predispose patients to further cartilage wear and eventual osteoarthritis. These injuries present a challenging problem with a multitude of treatment options and lack of consensus on when to employ each. Options include conservative measures (limited weightbearing and immobilization), debridement, microfracture, autologous chondrocyte implantation, and osteochondral autograft and allograft.
