Mental control ( psychological-competitive ability) is necessary for athletes to demonstrate their bestperformance. It has been assumed that an individual's personality is also involved in demonstratingpsychological-competitive ability; thus,the present study was conducted in order to clarify the relationshipbetween psychological-competitive ability and personality. The diagnostic Inventory of Psychological-Competitive Ability for Athletes ( DIPCA3) and Permeability Control Power Egogram ( PCE)were utilized to measure psychological-competitive ability and personality,respectively. University andhigh school athletes were categorized into superior and inferior groups,and a comparison was conductedbetween groups.Regarding the relationship between personality and psychological-competitive ability,it was suggestedthat university athletes in the superior group improved their competitiveness and cooperativenessby switching their ego-states appropriately,and self-confidence and strategic ability were loweredin the inferior group by repressing the expression of feelings into actions by the ego.High school athletesin the superior group had a strong desire to show their strength,and their egos motivated themto direct their mental stability and concentration,self-confidence,and strategic ability towards thisideal; however,a strong and dominant ego also lowered cooperativeness. In the inferior group,adominating ego that can be switched appropriately improved strategic ability or an ego that drivesathletes to act according to their own values and ideas improved self-confidence. It seemed that anego that represses the expression of feelings into actions lowered mental stability and concentration.Since the mental ability required of each individual varied due to differences in athletic level,careerand supervising method,different trends were observed between groups. In order to demonstratethe best performance for individual athletes at different levels,it is important to establish a personalitythat allows flexible switching of ego,and enhance mental competitive ability along with the establishmentof personality.

In a previous study,titanium seals were placed on university rhythmic gymnasts to ascertain psychological and physical effects.

Motor behavior couples with several types of environmental information perceived by actors. The phenomenon by which perceptions are distorted by the psychological state of an actor, including motivation, desire, and anxiety, is known as dynamic perception, and many athletes experience this under the psychological pressure of competition. The effects of pressure on the perception of target size before (pre-performance judgement) and after (post-performance judgement) a dart-throwing task and the relationship between size perception and performance outcome in the task were investigated experimentally. Healthy novice female university students (N=20) participated in the experiment. Pressure manipulations included performance contingent competitive cash rewards and comparative others. The results indicated that psychological and physiological stress responses were successfully induced, as indexed by significant increases in state anxiety and heart rate under pressure. Moreover, there were no significant differences in pre- and post-performance size perception between pressure and nonpressure conditions in all participants. However, participants with reduced throwing accuracy under pressure, as compared with non-pressure, perceived the target to be smaller under pressure in post-performance judgement. It is possible that attentional change including conscious processing and distraction, as well as kinematic changes, led to a decrement of motor skills performance that might have caused perceptual distortion under pressure. Exploratory multiple regression analysis to identify factors leading to perceptual distortions of target size under pressure indicated that participants reporting larger trait anxiety judged the target to be smaller in only preperformance judgement.
