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...
متن کاملYounger but Not Older Adults Benefit from Salient Feedback during Learning
Older adults are impaired in reinforcement learning (RL) when feedback is partially ambiguous (e.g., Eppinger and Kray, 2011). In this study we examined whether older adults benefit from salient feedback information during learning. We used an electrophysiological approach and investigated 15 younger and 15 older adults with a RL task in which they had to learn stimulus-response associations un...
متن کاملBelow-baseline suppression of competitors during interference resolution by younger but not older adults.
Resolving interference from competing memories is a critical factor in efficient memory retrieval, and several accounts of cognitive aging suggest that difficulty resolving interference may underlie memory deficits such as those seen in the elderly. Although many researchers have suggested that the ability to suppress competitors is a key factor in resolving interference, the evidence supportin...
متن کاملShort-term and long-term collaboration benefits on individual recall in younger and older adults.
A recent study of younger adults suggests that, compared to repeated individual recall trials, repeated collaborative recall trials produce better individual recall after a short delay (Blumen & Rajaram, 2008). Our study was designed to determine if such collaboration benefits would remain after a one-week delay, in both younger and older adults. Sixty younger (M age = 24.60) and 60 older (M ag...
متن کاملA positivity effect in autobiographical memory, but not phonemic fluency, in older adults.
To investigate whether processing fluency or cognitive control processes underlie aging-related positivity effects in memory, we compared retrieval of words on a fluency task, and of events on an autobiographical task, in younger and older adults. No positivity effect in word output was found on the fluency task, though older adults output more neutral words. For our autobiographical task, part...
