supporting generalized motor program theory at the behavioral level based on individual regression analysis: findings against especial skill effects

Background & Purpose:

Especial skills are a distinguished performance in one member within a class of skill which is a debate that has confliction with generalized motor program basis. Previous researchers have used the mean analysis of data, thus this study was conducted to determine the degree of generalized motor program's generalizability and especial skills by evaluating the role of experience level with individual analyzes.

To answer the research question, seven experienced dart players were asked to dart throw 252 throws from seven distances in which most practiced distances was middle distance, executed in three sets. Individual analysis of linear regression was performed to calculate predicted performance.

Final results showed that there was a significant difference between the actual and the predicted regression in the two samples B and E, which had a lower experience level than others, but there was no significant difference between the other samples with the more experience.

These findings revealed that especial skills are shaken at the behavioral level in the case of analysis of individual performance instead of an average analysis. On the other hand, the findings support the hypothesis that the level of experience and practice leads to a relative generalizability of the generalized motor program, which has a comparative relationship with the level of practice and repetition in one of the members of the skill class, and in contradiction with Findings of especial skills. These findings will draw interesting research questions and practical applications for future research.
