Praxis II Physical Education Exam Prep

Category - Physical Education

The ability to time movements to intercept a moving object, such as when catching a ball, is most dependent on an individual's ability to integrate motor behaviors with: 
  1. Sensory information about the speed and direction of the object.
  2. An understanding of how wind and air resistance affect the object's momentum.
  3. Visual information about the relative positions of body parts.
  4. Knowledge about the object's weight and the force with which it was propelled.
Explanation
Correct Response: A. To intercept a moving object, an individual uses visual, auditory, and other sensory information about the object's movement, including speed and direction, to direct body movements toward the object. The relative position of an individual's body parts is determined largely through proprioception, the perception of movement and spatial orientation arising from stimuli within the body, rather than through visual information alone (C). The effects of wind and air resistance (B) or the object's weight and the force with which it is propelled (D) influence the object's trajectory, but visual and other sensory information is used to instantaneously track and respond to any changes in timing and direction.
