Critical Flicker Fusion Predicts Executive Function in Younger and Older Adults

Critical Flicker Fusion Predicts Executive Function in Younger and Older Adults.

Critical flicker fusion (CFF), a measure of visual processing speed, has often been regarded as a basic metric underlying a number of higher cognitive functions. To test this, we measured CFF, global cognition, and several cognitive subdomains. Because age is a strong covariate for most of these variables, both younger (n = 72) and older (n = 57) subjects were measured. Consistent with expectat...

Motor Learning and Movement Performance: Older versus Younger Adults

Introduction: Motor skills play an important role during life span, and older adults need to learn or relearn these skills. The purpose of this study was to investigate how aging affects induction of improved movement performance by motor training. Methods: Serial Reaction Time Test (SRTT) was used to assess movement performance during 8 blocks of motor training. Participants were tested i...

Erg Assessment of Scotopic and Photopic Critical Flicker Frequency in Older and Younger Human Subjects

Effect of Different Cognitive Loads on Gait Stability in Younger and Older Adults

Purpose: As many older people fall during dual tasks, we aimed to examine the effect of different cognitive loads on learning gait stability in younger and older adults. Methods: 10 younger (Mean±SD age: 25.91±3.42 years) and 10 older adults (Mean±SD: 66.65±4.28 years) were healthy volunteers without a history of falls. They were asked to do three tasks on a treadmill with cognitive load (none...

FMRI activation during executive function predicts response to cognitive behavioral therapy in older, depressed adults.

OBJECTIVES To test our hypothesis that pre-treatment executive function and brain regional activation during executive function would discriminate between responders and non-responders to cognitive behavioral therapy (CBT) in elderly depressed outpatients. DESIGN Clinical cohort study. SETTING University-affiliated hospital. PARTICIPANTS Sixty outpatients (age 59 years and older) complete...
