This study attempted to investigate the relationship of achievement goal orientation and competitive state anxiety to motor performance outcomes and attributional patterns elementary school boys. The subjects were 80 elementary school boys partivipated in their 5th grade. TEOSQ CSAI-2, and Attribution-Success and Failure Scale were used as instrumental tools. In order to test the hypothesis of the study, one-way ANOVA and correlation analysis were used. The implications of the study are as follows: 1. Achievement goal orientation and competitive state anxiety had no significant effect on motor performance outcomes. 2. Achievement goal orientation and cognitive-anxiety somatic anxiety had a significant effect on attributional patterns in success situations. Task-orientation group perceived the cause as an effort factor in success situations. 3. Achievement goal orientation and somatic anxiety had a significant effect on attributional patterns in failure situations. Task-orientation group perceived the cause as an luck factor in failure situations. 4. Achievement goal orientation and self-confidence had a significant effect on attributional patterns in failure situations. Tast-orientation group perceived the cause as an luch factor and ego-orientation group perceived the cause as an effort factor in failure situations. 5. There were significant correlation between ego-orientation and cognitive-andiety, and somatic anxiety in success situations.
