1. Left-handed athletes have been shown to have an advantage in interactive sports such as tennis, with left-handers making up a disproportionately high percentage of top players. 2. One theory for this advantage is the "negative perceptual frequency effects" hypothesis, which suggests that right-handed athletes are less practiced at perceiving and predicting movements from left-handed opponents. 3. A study tested this by having right and left-handed participants with different levels of tennis experience try to predict the direction and depth of tennis shots from video clips of both right and left-handed players. It found support for the idea that the ability to perceive left-handed movements is less developed.

- 9. Perception of Human Movements1.Focus of orientation in the perception of humanmovements. -These studies assume that this sensitivity in distinguishing between different human movements depends on visual experience.
- 10. Perception of Human Movements2. Side-specific perception of human movements in sport. - This strong dependence on both visual experience and the horizontal orientation, it is proposed the sport-type-specific ability with the left hand is less well developed.
- 11. Perception of Human MovementsNegative perceptual frequencyeffects hypothesis. -The lower frequency with which athletes in interactive sports are confronted with movements by left-handed opponents.

- 21. DiscussionThe ability to discriminate left-handed movement patterns is less well developed than that for right-handed movement patterns.

- 24. DiscussionDo the Movement Patterns of left-Handers Simply Mirror the Movements of Right-Handers?There should also be no interaction between the playing hand in video and initial handedness of player in video variables.
- 25. DiscussionNegative perceptual frequency effect (see Faurie & Ray-mond, 2005) and can be assigned to the set of strategic advantages of left-handers in sport.
