DEPTH PERCEPTION WITH RELATION TO PERSONALITY & INTELLIGENCE OF PLAYERS

Book excerpt: Depth perception refers to the ability to distinguish the distance of objects or to make judgments about relative distance. This capacity also called distance perception, adds the third dimension to height and width. Binocular vision (simultaneous vision with both eyes) is the primary basis for depth perception. The two eyes focus on an object from depth in one’s perception. Monocular vision (seeing with one eye) tends to flatten things in the distance. In motor activities, there are many opportunities for making judgments about the distance of people or objects. For example, the passer in football needs to determine with considerable accuracy the distance of his receivers and his opponents. Similarly the receiver must be able at all times to make an accurate judgment about the distance of the thrown ball. The golfer on the fairway must make an accurate estimate of the distance of the pin so that he can determine which club to select and how hard to swing. The high jumper, pole vaulter, or broad jumper in track needs to make an accurate estimation of the distance to the take-off point. Or he will be required to make a last second adjustment in stride. A misjudged fly ball in baseball results from a poor estimation of the distance and speed of the ball. The batter with poor depth perception is most susceptible to a change-up pitch. In most motor activities, and especially in ball games, the ability to distinguish distances is strategic to efficient performance.
