Raeanne Moore & colleagues found that individuals who engaged in cognitively stimulating activities scored better on cognitive performance tests than those who engaged in passive, less mentally taxing pursuits.

 

Raeanne C. Moore and colleagues published a paper on "Daily Activities Related to Mobile Cognitive Performance in Middle-Aged and Older Adults: An Ecological Momentary Cognitive Assessment Study".

Working, reading and other cognitively stimulating activities are related to better cognitive functioning. Conversely, studies have found that passive activities such as watching television are related to worse cognitive functioning. One problem with the current research on understanding the relationships between daily activities and cognitive functioning is that cognitive testing is usually done on a single day in a lab, which may not reflect real world cognitive performance. In this study, we used smartphones to test participants’ cognitive functions multiple times a day immediately after different types of activity (i.e., at different times during the day, participants’ smartphones would survey what they were doing and then ask them to complete a short cognition test.). The cognitive abilities we tested were executive functioning and learning.

HNRP at INS 2021

Several HNRP investigators contributed to the International Neuropsychological Society (INS) Annual Meeting in San Diego (virtual event) on February 2-5, 2021. This year's theme was: From Autism to Alzheimer's: New Perspectives in Neuropsychology. HNRP researchers presented on topics such as cognition, HIV, substance use, medical measures and behavior.
