Objective1, Discussing the relationship between the basketball affordance perception andshooting accuracy.2, Exploring influence factors of basketball affordance perception.3, Exploring the way of basketball affordance perception learning.Methods1Literature: understanding the research status and dynamic by the Shanghaisports university library about topics related to affordance study literature, At thesame time, reading the aspects of physiology, psychology, sports training book,looking for theory and practice basis for this study.2Experiment: according to the experiment purpose, selecting different subjects,experimental results are obtained through the experiment design, experimentprocedure and experimental condition control.3Mathematical statistics: adopting spss20.0statistical software to deal with theexperimental data according to different experimental purposes, including therepetitive measurement of variance, correlation analysis, etc.ResultsExperiment one results: The novice’s affordance perception by dynamictouch and shooting accuracy are not positive correlation, there is positivecorrelation between expert athlete’s affordance perception, by dynamic touch, andshooting accuracy.The repetitive measure analysis of variance at novice’s perception preferenceresults: there are basketball material including super fiber, pvc, rubber impactingon novice’s perception preferences, which are very significant differences eachother. The super fiber basketball preference’s score is the biggest, the pvcbasketball is second, the rubber basketball is the smallest. Weight affect novice’sperception preferences, there is significant difference among the number7,6,5basketball. The number6basketball preference score is the biggest, the number7basketball is the second, the number5basketball is the smallest. The statisticalresults of novice’s shooting accuracy show that the main effects of the materialand weight are not significant.The repetitive measure variance analysis of perception reference results: Thematerial and weight affect expert’s perception preference. There are basketball material including super fiber, pvc, rubber impact on expert basketball perceptionpreferences, which are very significant differences each other. The super fiberbasketball preference score is the biggest, the pvc basketball preference score issecond, the rubber basketball is the smallest. Weight affect experts perceptionpreferences, there is significant difference between the number7and5basketball.,Also between the number6and the number5basketball. The number7basketballpreference scores is the biggest, the number6basketball is second, the number5basketball is the smallest.The repetitive measure variance analysis of expert’s basketball shootingpercentage results: the main effects of material and weight are significant,material and weight influence on expert’s shooting percentage. There is nosignificant difference between the super fiber and pvc basketball, the super fiberand rubber basketball exist significant differences, also the pvc and rubberbasketball. From different material basketball shooting percentage, the super fibershooting percentage is the highest, the pvc basketball is second, the rubberbasketball is the lowest. There is no significant difference between the number7and number6basketball, there is significant between the number7and number5basketball, also the number6and number5basketball. The number7basketball’sshooting percentage is the highest, the number6basketball is second, thenumber5basketball is the lowest.Experiment two results: from the mean value of perception preferenceabout material, the male’s basketball athlete and female’s basketball athlete’sperception preference order are same. The super fiber basketball’s perceptionpreference value is the biggest, the pvc basketball is second, the rubber basketballis the smallest. Weight and gender exists interaction, fixed gender factors, weightthat is in levels of gender are different. at male level, the basketball weight ‘sperception preferences exist significant difference, the number7basketball’sperception preference value is the biggest, the number6basketball is second, thenumber5basketball is the smallest. At Woman level, the basketball weight’sperception preference exist significant difference. The number6basketball’sperception preference value is the biggest, the number7basketball is second, thenumber5basketball is the smallest. The male’s basketball players prefer theheavier basketball, the female’s basketball athletes prefer the lighter basketball.The main effects of material and weight are significant, material and weight influence on shooting percentage. The super fiber and pvc basketball are nosignificant different, the super fiber and rubber basketball exists significantdifferences, also the pvc and rubber basketball. The super fiber basketball’sshooting percentage is the highest, the pvc basketball is second, the rubberbasketball is the lowest. There is no significant difference between the number7and number6basketball, there are significant differences between the number7and the number6basketball, also the number6and number5basketball. Thenumber7basketball shooting percentage is the highest, the number6basketball issecond, the number5basketball is the lowest.The shooting percentage between the male basketball athletes and the femalebasketball athletes is not significant difference. The male basketball athletesperception preference and shooting percentage are positive correlation, the femaleperceive preferences and shooting percentage are significant positive correlation.Experimental three results: before shooting, with increased task difficultyincrease (distance increase), the basketball’s affordance perception is reduced, butat the end of each distance shooting location, the number6basketball is perceivedthe most suitable for shooting. After shooting, as the task difficulty increases(distance increases), the basketball’s affordance perception is reduced, but thebest ball chosen is the number6basketball in each distance shooting location.At shooting stage, with distance increase, the shooting percentage is reduced,but the shooting percentage does not increase with basketball weight reduction.Correlation analysis of the affordance perception and shooting percentagebefore shooting, at4.25m shooting location, there is significant positivecorrelation about affordance perception and shooting percentage of three kindbasketball; at5.25m shooting location, there is significant positive correlationabout affordance perception and shooting percentage between the number7andthe number6basketball, the number6correlation coefficient is larger. At6.25mshooting location, there is significant positive correlation only about the number6basketball affordance perception and shooting percentage. At4.25m shootinglocation, there is significant correlation of number7,6basketball’s affordanceperception and shooting percentage, there is no significant correlation aboutaffordance perception and shooting percentage in the number5basketball. At5.25m shooting location, the number7,6basketball is positively correlated toaffordance perception and shooting percentage, but the number6basketball affordance and shooting percentage’s correlation coefficient is more larger; At6.25m shooting location, there is a positive correlation between affordanceperception and shooting percentage in the number6basketball. The correlationbetween affordance perception and shooting percentage before and aftercomparison, with the increase of distance, affordance perception and shootingpercentage’s correlation, only the number6basketball’s affordance and shootingpercentage is significant.Experiment four results: the novice’s perception preference and shootingpercentage is positive correlation. After8weeks shooting training, theparticipant’s shooting percentage gets significantly higher. The participant’sperception preference also produces change, although the super fiber7,6,5basketball’s perception preference is no significant difference, compared beforeand after training, the perception preference value enlarges after training. The pvc7and rubber7number basketball’s preference value are no significant difference,but after training, the preference value decrease. And the pvc6, pvc5, rubber5,rubber6basketball have a statistically significant difference, compared before andafter the training, basketball perception preference values decrease.Conclusions1, There is a positive correlation between basketball affordance perception andshooting accurate for basketball player with basketball experience, there is anegative correlation between basketball affordance perception and shootingaccurate for novice with no basketball affordance. The basketball is perceivedmore suitable, it is shot more accurate for the basketball players with experience.2, Beating the basketball is exporing action of basketball affordance perception,the weight and the material of basketball are the key information of affordanceperception,of basketball.3, Sport experience, gender and task difficulty influence on the basketballaffordance perception differences.4, The basketball shooting’s practice process contains affordance perceptuallearning. In process of basketball affordance’s perceptual learning, throughconstant practice learners gradually learn which basketball is more suitable forshooting.
