Personal Ability Inventory:
Multi-limb coordination-4
Control Precision-3
Response Orientation-5
Reaction Time-5
Rate control-4
Manual Dexterity-2
Finger Dexterity-5
Arm-hand steadiness-3
Wrist-finger speed-5
Aiming-2
Explosive Strength-4
Static Strength-2
Dynamic Strength-3
Trunk Strength-4
Extent flexibility-4
Dynamic Flexibility-3
Gross body equilibrium-3
Balance with visual cues-4
Speed of limb movement-5
Gross body coordination-3
Stamina-4
Movement rate-5
Motor timing-4
Perceptual timing-2
Force control-4

5 Skills I can perform with a high level of proficiency:
1. Soccer penalty kick
2. Typing on a keyboard
3. Threading a needle
4. Balancing on a ropes course
5. Playing air-hockey

Ideal Ability Profile for Playing Air-hockey:
-reaction time
-rate control
-arm-hand steadiness
-aiming
-motor timing
-force control

Discussion:
I think there are a number of ways that a person who is not naturally skilled at playing air-hockey can improve their performance.  One of the most important factors needed in order to be good at air hockey is reaction time. The puck moves very quickly across the playing surface and a player needs to be able to react quickly to deflect shots and prevent goals.  However, some players may not have a good reaction time, so in order to compensate for this, they should work on accurately anticipating where they think the puck might go based on body positioning and arm speed of their opponent. If the player is able to predict where the puck is going to travel, they won't have to react as quickly to get there. Another area an air-hockey player needs to be good at is aiming.  The slot the puck can slide into is very small and the puck is moving so quickly that it can be difficult to aim for that tiny opening.  This is an area that I am not very good at and I ranked myself as a "2" in that category, especially under conditions where quick choices and speed are necessary along with accuracy.  In order to compensate for a lack of natural ability in this area, I instead use force control.  If the puck is sometimes moving very forcefully towards the goal and sometimes bouncing around more slowly, if is difficult for the other player to determine what type of shot is coming next.  They are unlikely to be able to guard their goal against every different type of shot so even if your aim isn't perfect, you can still distract your opponent and score on some of the less accurate shots.

PDFE #6: General Motor Ability

For this PDFE experience, we did a lab to test and see if any one person has a general motor ability (the ability to perform the best in every movement activity).  To test this, we got into a group of 6 and performed a variety of balance exercises. The 6 exercises were the stork stand (balancing on one foot), the diver stand (balancing on two feet with arms flexed), the heel stand (balancing on two heels in ready position), the sideward leap (jumping side to side on alternating feet and touching ankles), bass stepping-stone (jumping forward on alternating feet and then turning around on one foot), and book walk (balancing a book on the head while walking).  In that order, the results for our lab were:

Meredith: 3,1,6,2,3,2
Amanda:  5,2,5,3,6,5
Lindsay:   1,3,4,1,1,3
Robert:     4,5,3,5,1,1
Bethani:   6,6,2,3,3,4
Jeff:         2,4,1,5,3,6

As indicated by our results, some people did better than others overall, but everybody had a range of scores which means no person excelled on every single activity. The person who did the best in our group overall, Lindsay, had a background in ballet which helped her on her general balance abilities, but even she scored 4th places on one of the activities.  Based on this information, I think people do not usually have a general motor ability.
