The following characteristics I will describe in video clips one, three, four, and seven of the chapter one lab activity will help me identify and rank which of the people in these four videos is the most developmentally advanced, specifically in the motor skill of throwing a ball. First, I will identify the most proficient ball thrower and then create a developmental “throwing continuum” from the most to least advanced. Following this continuum, the constraints important to the throw will be explained as well as how a change in one constraint might change the throwing pattern.
On my “throwing continuum” the number one is the lowest rank, meaning least developmentally advanced, in contrast with the number four ranking most developmentally advanced. Chapter One Lab Activity “throwing continuum” is visually represented bellow:
Ranking: 1 2 3 4
Video clip #: #7 #1 #3 #4
This representation displays that the person in video clip number four is the most developmentally advanced at the motor skill of throwing a ball, followed by video clip number three as the second most advanced, then video clip number one coming in third, and lastly video clip number seven ranked number one on the “throwing continuum,” as the least proficient.
What makes these videos distinguishable in terms of developmental advancement are the characteristics of each person’s throw. Video clip number seven ranked the lowest on the continuum because he showed a lack of experience expressed in characteristics such as the loss of balance, shallow throw, slight tilt of the ankle, and using a larger ball. Video clip number one was ranked second because considering his feet stayed stationary and together, and that he reached the ball behind his head to gather speed, make it evident that he is still primitive; yet,...
