The Development of Infant Motor Skills: Current Research and Ethical Considerations

Please note: exam questions are subject to change.

1. Which of the following statements demonstrates the cephalocaudal trend? During infancy and childhood, the legs and arms grow somewhat ahead of the hands and feet. At birth, the head takes up one-fourth of total body length, the legs only one-third. In the prenatal period, the head, chest, and trunk grow first; then the arms and legs; and finally, the hands and feet. During infancy and childhood, the hands and feet grow somewhat ahead of the fingers and toes.
2. Which of the following statements is consistent with the proximodistal trend of body growth? During the prenatal period, the head develops more rapidly than the lower part of the body. During infancy and childhood, the body grows from “head to tail.” During the prenatal period, the trunk grows first, followed by the chest and the head. During infancy and childhood, the arms and legs grow somewhat ahead of the hands and feet.
3. A researcher hangs a mobile over the crib of 4-month-old Anya. When the researcher attaches Anya’s foot to the mobile with a long cord, Anya can, by kicking, make the mobile turn. The turning of the mobile is an example of: a reinforcer. punishment. an unconditioned stimulus. an conditioned response.
4. Which of the following is an example of a gross-motor skill? climbing pointing reaching scribbling
5. Which of the following is an example of a fine-motor skill? standing throwing sitting up grasping
6. Four-month-old Kaitlyn reaches for a toy. She grabs it by closing her fingers against her palm. Kaitlyn is using the pincer grasp the grasp reflex the ulnar grasp pre-reaching
7. By the end of the first year, a baby’s ability to manipulate objects greatly expands with the development of the pincer grasp the ulnar grasp the fine-motor reflex pre-reaching
8. Held and Hein’s kitten study in which one kitten was allowed to navigate normally and one kitten was riding in a cart illustrated that only visual stimulation is necessary to develop normal perceptual-motor abilities. action, visual stimulation, and perception are all necessary to develop normal perceptual-motor abilities. the kitten riding in the cart became blind. visual stimulation is not necessary to develop normal perceptual-motor abilities.
9. In Piaget’s sensorimotor stage, infants and toddlers assimilate more than they accommodate. represent their experiences in speech, gesture, and play. “think” with their eyes, ears, hands, and other sensorimotor equipment. solve every day practical problems and carry out many activities inside their heads.
10. In Piaget’s theory, a circular reaction is a means of building schemes in which infants attempt to form mental symbols of the world. try to repeat chance motor activities again and again. try to imitate the behaviors of others around them. attempt to act out imaginary activities.
