The King-Devick test can accurately distinguish between cognitively healthy individuals and those with cognitive impairment over 90% of the time.
A Clemson University psychology professor found that incorporating light physical activity into work or study improves mood, motivation, and morale, while maintaining cognitive performance. The study suggests that sedentary work may not be harmful in the short term, but long-term effects could lead to chronic disease and physical frailty.
A new study suggests that higher late-life cognitive reserve is linked to lower incidence and severity of delirium in older surgical patients. Participating in cognitively stimulating activities such as reading, singing, or playing computer games may help protect against delirium.
Adolescents outperform adults in choosing rewards but struggle with punishment, leading to the development of a new model for learning during adolescence. The study suggests that incentive systems based on reward rather than punishment may be more effective for this age group.
A new study from Ohio State University found that unemployed individuals who use skills commonly taught as part of cognitive therapy for depression are more likely to receive a job offer. These skills include identifying negative thoughts, countering them with positive responses, and planning enjoyable activities to improve mood.
A new study at CU-Boulder found that empathy for others' pain is rooted in cognitive neural processes rather than sensory ones. The research suggests that empathy involves mentalizing and taking another person's perspective, distinct from experiencing physical pain.
A study by the Center for BrainHealth found that strategy-based reasoning training can improve executive function and memory span in individuals with mild cognitive impairment. The training focused on higher-level brain functions such as strategic attention, integrated reasoning, and innovation.
Researchers at Simon Fraser University developed the mySleepButton app using a 'cognitive shuffle' technique called Serial Diverse Imagining (SDI). The method helps reduce pre-sleep arousal and improves sleep quality by keeping the mind off issues that disrupt sleep.

Research in this area aims to delay cognitive decline in the elderly, reducing welfare costs and improving overall quality of life.
A study by MIT neuroscientists reveals that the Shank gene plays a crucial role in the formation and maturation of synapses. In fruit flies lacking this gene, researchers found reduced functional synapses and improper development, which could impair neural circuit development and contribute to autism symptoms.
A recent study by York University researchers found that children and adolescents with a history of concussion experience prolonged difficulty in cognitive-motor integration. This impaired function can last for up to two years before they can perform tasks as skillfully as their peers without a concussion history.

When drivers are distracted or upset, their brain's automatic error correction system helps them stay on course, but texting significantly disrupts this process.
A new UCL study found that bad experiences are strongly remembered, but surrounding context is weakly recalled due to reduced activity in the hippocampus. This imbalance can lead to strong but fragmented memory for traumatic content, contributing to post-traumatic stress disorder symptoms.
Research on neural network interactions and related brain activity patterns provides insights into thought processes that make people vulnerable to depression. The study identifies increased activity in one important brain network, called the default mode network, which may contribute to maladaptive rumination.

In a study, MS patients showed more severe moral judgments than average, even in neutral conditions, attributing negative emotions to external causes. This 'externally oriented thinking' helps them minimize damage but also leads to an inability to reflect on emotions and identify real causes of their negative emotional state.
A recent study examined the relationship between empathy and understanding others' mental states. The findings suggest that people who tend to be empathic do not necessarily understand other people well at a cognitive level. Social skills seem to be based on multiple abilities that are independent of each other.
A new study found that bi-dialectal children exhibited similar cognitive advantages as multilingual children, including improved memory, attention, and cognitive flexibility. The research suggests that the ability to switch between two dialects of the same language provides mental stimulation and leads to higher cognitive performance.

Cognitive training on speed of information processing resulted in a 50% greater effect for those with less than a complete high school education.
A study found that genes associated with diseases like Alzheimer's, schizophrenia, and autism also impact cognitive functions. Researchers analyzed data from 100,000 people in the UK Biobank to discover shared genetic influences between health and thinking skills.
Researchers found that regions of the brain normally working together to process emotion become decoupled in people who experience multiple episodes of depression. This disruption may lead to inaccurate emotional information processing and negative biases.
Researchers found that high-challenge activities improved memory performance and brain activity efficiency in older adults. The study suggests that mentally demanding activities may be neuroprotective and essential for maintaining a healthy brain into late adulthood. Enhanced neural efficiency was maintained a year after participation.
Neuroscientists argue that computers will never truly understand human communication due to lack of contextual understanding. Brain scans reveal areas of the brain where 'meeting of minds' occurs, enabling nonverbal mutual understanding.
Turn-taking in human communication appears to have origins in primate gestural interactions, predating the development of language. This double-tasking of comprehension and production may motivate compact clause structures in all languages.
