The Effect Of Random, Blocked, And Transition Practice Schedules On Children's Performance Of A Barrier Knockdown Test, Gregory C. Snider Mar 2009

The Effect Of Random, Blocked, And Transition Practice Schedules On Children's Performance Of A Barrier Knockdown Test, Gregory C. Snider

Master's Theses

The purpose of this research was to examine whether a transition schedule of contextual interference facilitated learning in retention and transfer equal to or better than random and blocked schedules among children. The author selected participants from the central coast of California and from youth activity leagues. The author selected children between the ages of 10 to 13 with a mean age of 11.5. There were a total of 36 subjects, half male and half female. Unfortunately, due to computer error, only data from 15 subjects were saved and available for analysis. Researchers randomly assigned participants to one of three …


The Effects Of Alterations To Upper Limb Inertial Properties On Vertical Point-To-Point Movement, Adrian K. Hongo Mar 2009

The Effects Of Alterations To Upper Limb Inertial Properties On Vertical Point-To-Point Movement, Adrian K. Hongo

Master's Theses

Purpose: Several studies have examined intralimb coordination between the shoulder and elbow joints during target-oriented movements. These studies have observed consistent patterns in coordination despite changes in movement variables such as speed, direction, and inertia. Researchers used intersegmental dynamics to quantitatively analyze these patterns between shoulder and elbow joints while systematically changing values of these movement variables. Some studies have examined central nervous system adaptations to inertial changes at the elbow and entire arm during a movement, but none have examined inertial changes to the upper limb. Methods: Five male and five female participants aged 27 to 39 years (mean …
