Unformatted text preview: 1. Differentiated rotation is the most mature step for trunk and pelvis action during the throw. This pattern allows the child to a. Freeze the degrees of freedom, thereby reducing the complexity of the task. b. Exploit the passive/reactive forces of movement in developing high velocity of the throwing hand. c. Stabilize the increasing proportions of the body mass over the base of support. 2. Using the component approach, which of the following is the correct developmental sequence for trunk action in throwing? a. forward/back - block rotation - differentiated rotation b. block rotation - spinal extension - forward/back - differentiated rotation c. forward/back - differentiated rotation - homolateral (ipsilateral) stepping d. block rotation - spinal extension - homolateral (ipsilateral) stepping 3. The second developmental step for humerus action in the throw is a. humerus aligned but independent b. humerus oblique c. humerus lag 4. Why is the component analysis approach better than a whole-body approach to understanding motor skill development? a. The component approach involves fewer stages of development, thus it is easier to classify a child's developmental level. b. The whole-body approach is appropriate only for beginners. The whole-body approach is not valid for skilled performers. c. Components develop at different rates. Thus the component approach makes possible a more accurate assessment of skill development. 5. Obesity in children is a major health problem. Current medical practice is to recommend dietary restrictions for the purpose of weight loss when a. a child of any age exceeds the 85 th percentile on BMI b. a child under 7 years of age exceeds the 95 th percentile on BMI c. a child over 7 years of age exceeds the 95 th percentile on the BMI 6. What proportion of children between 5 and 10 years of age and over the 95 th percentile for BMI show clinical signs of hypertension. a. 20% b. 40% c. 60% d. 80% e. 100% 7. At birth, the sensory systems are fully functional, though lack their full acuity. As important as the development of individual sensory systems is the coordination of sensory information across different sensory modalities. Which of the following statements accurately represents the development of sensory integration? a. sight and sound are coordinated by 2 months and sight and touch are coordinated by 5 months of age. b. sight and sound are coordinated by 4 months and sight and touch are coordinated by 9 months of age. c. sight and sound are coordinated by 6 months and sight and touch are coordinated by 9 months of age. d. sight and sound are coordinated by 9 months and sight and touch are coordinated by 14 months of age. 8. Based on Haith’s theory of visual perception, which of the following mobiles will be most interesting to infants?...
