Effects Of Age On Motor Preparation And Restructuring, Paul Amrhein, Noreen Goggin, George Stelmach

Age-related decrements in motor plan restructuring were investigated. In this experiment, older and younger adults performed a discrete aiming task that involved responses that were precued and responses that were modified at the time of an imperative signal. On 75% of the trials, the precue specified the response-stimulus (valid trials) with respect to the movement parameters of the arm (left or right) and direction (toward or away). On the remaining 25% of the trials, the response-stimulus was different from the precue (invalid trials) in that the subject was required to modify a planned movement by changing the arm to be …

Subject-Generated Verbalized Strategy And Error Estimation During Skill Acquisition, Kent Darby Wagoner

Dissertations and Theses @ UNI

The purpose of this study was to examine the effects of subject-generated verbalized strategy during the post-KR delay interval on motor learning of college-aged students. A second purpose of the study was to replicate the Hogan and Yanowitz (1978) experiment and examine the effects of subject-generated verbalized error estimation on motor learning. Additionally, this study examined the interaction effects of verbalized strategy and verbalized error estimation on motor learning of college-aged students. Based on the conclusions drawn from relevant literature it was hypothesized that subject-generated verbalized strategy and verbalized error estimation during skill acquisition would enhance learning.
