We purpose to examine to resolve methodological problems faced when trying to analyze the perceptual-motor skills. We consider KARATE for that purpose. We point out that not only S-R model and S-O-R model, but also the sensoy-motor coordination theory are not anadequate to analyze KARATE. We present a new analytical shema from the stand-point of structuralism which has 3 properties: wholeness, transformation, and self-regulation.
We studied the same beginners' motions in KARATE matches for 2 yrs in the frame of our new analytical shéma.
Some results are as follows:
a) “Motion Space” gradually expanded through 2 yrs.
b) A rythm of body was appeared after 1 year. It seems to aim the preparing the next motion.
c) Displacements of subjects changed gradually from “strait lines” to “curved lines” and the inside of a motion gradually differentiated.
d) The tendencies of their appearance are statisticaly significant (p<001). We can present such changes as the producing a mathematical displacement group.
e) A player who can absorb his opponent's motion structure into a subgroup of his own motion structure is certain to win a match.
f) A player perceives his opponent's motion in the frame of his structured Motion Space. We carried out 2 kinds of researches about this hypothesis. One was the research about the perception of opponent's no-guarded points in the matches. We found the difference between beginners and experts on that perception (p<.01). The other research was the unusual perceptions of the highest experts. We got 150 answers of experts and its 58% was that as we expected.
