Primarily, the purpose of the present study is to clarify the psychological aptitude of female hockey players concerning the dual construction personality theory. Subjects were divided into two groups which were High Level Group (HLG: Players took a part in the 4th intensive training camp. N=32) and Average Level Group (ALG: Players at middle level. N = 30). MPI (Maudsley Personality Inventory) as measured inner personality side and TSMI (Taikyo Sport Motivation Inventory), SF (Stage Flight) and WP (Will Power) as measured outer personality side were administered. As the results, the following tendencies were found out: 1) There was no significant difference between HLG and ALG on the scores of E and N scale, but the both groups exhibited higher extroversion than the criterion groups. 2) There were significant difference between the two groups on the Factor 4 (HLG 23.938, ALG 18.567; P.05). 5) The Correlation Coefficient between extroversion and Factor 2 of TSMI was significant for HLG (r=.507, P.05). 6) The Correlation Coefficient between extroversion and Factor 14 of TSMI was significant for HLG (r=.496, P.05). 7) The Correlation Coefficient between extroversion and Factor 16 of TSMI was significant for HLG (r=.573, P.05). 8) The Correlation Coefficient between neuroticism and Factor 13 of TSMI was significant for HLG (r=.505, P.05). 9) The Correlation Coefficient between neuroticism and SF was significant for HLG (r=.538, P.05). Viewing from the above results, it appears that tendencies of extroversion and high achievement motivation are very important psychological aptitudes for the high level female hockey players.
