Aging and Learning New Complex Tasks

What’s This Research About?

To determine whether older adults benefit from random order practice or
blocked practice when learning a complex, bimanual task.

Retention of a learned skill is affected by how we practice. Older adults may
experience a loss of performance levels during various motor tasks; in order to
regain those skills, it is necessary to practice in an effective way that allows for
retention. Contextual interference (CI) is a method used to improve retention
by practicing task variants in a random order. This is in contrast to practicing
the same variant repeatedly, or through blocked practice. CI is an effective way
to learn and retain simple motor tasks; however, whether CI is effective for more
complex tasks is unclear. Little research has been done to answer whether older
adults benefit from CI as a practice method for learning complex tasks.

Suggested hypothesis: It has been demonstrated random practice leads to better
skill persistence in both high and low complexity task variants; as a result, the
authors hypothesize random practice will lead to better skill persistence in low
and high complexity task variants in both young and old adults.

TITLE: Challenge to promote change: both young and older adults benefit from contextual interference

Motor learning: A set of processes associated with practice or experience leading to relatively permanent changes in movement capability.

Blocked practice:  when a learner performs a single skill over and over, with repetition being the key. Variance in training is minimized or nonexistent. The learner then moves on to practice another discrete skill in the same way.

Contextual Interference Effect (CI effect):  The learning benefit that results from practicing task variants in a random practice order.

About the Author:

Jenn Pilotti has a BS in exercise physiology from UC Davis. After graduating in 2002, she was hired by the Beach and Tennis Club at Pebble Beach as a full time personal trainer. While there, she had the privilege of working with individuals of all ages, many of whom had aches and pains from a life well led. This piqued her interest in injuries, prevention, and pain. After years of undirected self study (and after leaving the security of a full time position to go out on her own), she enrolled in an online program through AT Still University, eventually acquiring a master's in human movement while working full time. After graduating, she continued to read research and write about its application to her work with clients. She fell in love with yoga in 2004, finally became 200 hour RYT in 2014 after years of workshops and self study (there seems to a theme), and continues to study somatic disciplines. She is DNS exercise trainer certified, FRCms, MovNat level I certified, GMB trainer certified, has taken PRI respiration, myokinematics, impingement and instability, and pelvis restoration, and has read an embarrassing number of books on movement, psychology, and wellness. She has an insatiable curiosity about what makes for a healthy person, physically and mentally, and she finds herself often asking why things work for some and not for others. She strongly believes in the power of knowledge and the power of movement. Learn more about Jenn Pilotti.
