Choice Reaction, Part 4

The foregoing diagram and the theory about availability of information from the blog entry Choice Reaction Time, Part 1 opens another interesting approach to cut choice reaction times. You should look for patterns, which summarize alternatives instead of too specific things. Patterns that exclude as many alternatives as possible are preferable to those that deal […]

Choice Reaction, Part 3

The following robot wins every game. He has a high speed camera to look at his opponent’s movements. His tree diagram has the same patterns and the reaction chain has all elements of a choice reaction. The difference lies in the speed of his pattern recognition and the movement execution.   “Rock, Paper, Scissor” robot […]

Choice Reaction, Part 2

The blog entry Choice Reactions, Part 1 was very theoretical, so now some examples. The game “Rock, Paper, Scissor” is a typical example of a choice reaction. If you are not familiar with the rules, please take a look at this article or this video. First, try to find a relevant pattern and put it […]

Choice Reaction, Part 1

Choice reaction times are a very special subject. One can find many comparisons of studies and background information at Schmidt and Lee [1]. There is a tendency towards rising reaction times due to an increasing number of choices. A direct linear relationship doesn’t seem to exist. The relationship seems to be rather an increase with […]

Application of Patterns and Traits, Part 2

The blog entry “Application of Patterns and Traits, Part 1” brought patterns and causal relationships into focus. This example will further bring out the necessity for the causal relationship between patterns and the following movements. In the movie “The Pink Panther Strikes Again” [1], Inspector Clouseau, alias Peter Sellers, allows his servant Cato to surprise […]

Application of Patterns and Traits, Part 1

If you practice martial arts long enough, you will know the disadvantages of long lunge movements. I will discuss these things in future blog entries in detail. Thus, the following example from the movie “Watch Out, We’re Mad!” [1] only gives a little introduction. Please concentrate on the movements which, due to their early initiation, […]

Definition Patterns and Traits

There are different definitions for traits and patterns, depending on the fields (motor control, psychology, …). For this blog, it should not be too complex. A simple definition suffices, which might be adjusted later. There are also other words used for these relationships like clue, lead, indication, cue, etc. Patterns and traits can be used […]

Reactions and Patterns

Every fight consists of a special combination of boundary conditions (goals, rules, etc.). Martial arts are forced to find suitable patterns that allow an evaluation, even though each situation looks different to outsiders. These patterns range from very simple traits, like wrist rotation or posture change, to very complex patterns like movement of the upper […]

Comment on Choice Reaction Times

The previous example from the movie After the Rain [1] has shown that the unambiguous assignment of reaction types is only partly possible. If you want to give a student an understanding of these relations, you should focus on the individual components of the reaction chain.     Usually, students look at movements as choice […]

Examples for Various Types of Reactions

A short scene from “After the rain” [2] can act an example for all previous types of reactions. Depending on how one arranges things, you can end up with different types of reactions. If the response selection has to be done in a very short time, then you can classify it as a part of […]
