Question Answer
Motor Programing say the brain sends signal every time to move arm and then the arm moves
Dynamical Systems the arm needs to move and therefore it unfolds without the brain having to send a signal every time
Skills involve achieving some well-defined environmental goal in these ways 1. Maximizing the certainty of goal achievement 2. Minimizing the physical and mental energy costs of performance 3. Minimizing the time used
Three elements are critical to almost any skill 1. Perceiving the relevant environmental features 2. Deciding what to do and where and when to do it to achieve the goal 3. Producing organized muscular activity to generate movements that achieve the goal
Discrete Skills Usually have an easily defined beginning and end, often with a very brief duration of movement (e.g. throwing a ball, firing a rifle, or turning on a light switch)
Serial Skills A group of discrete skills strung together to make up a new, more complicated skilled action (e.g., shifting gears in a car). The word serial implies that the order of elements is usually critical for successful performance
Continuous Skills Arbitrary beginning and end points, the behavior flowing for minutes or hours (e.g. swimming and knitting)
Constant Error (CE) Average all the scores for each subject Interpreted as an overall tendency to underthrow or overthrow the target
Absolute Error (AE) Considered the absolute value (e.g., with the sign ignored or removed) of the error on each trial, and take the average of those error scores for the various trials Interpreted as one person or group being more off target than another
