Briefly explain proximodistal development in infants.
What will be an ideal response?
Answers will vary. The development of hand skills is an example of proximodistal development. Infants will track slowly moving objects with their eyes shortly after birth, but they will not reach for them. Voluntary reaching and grasping require visual-motor coordination. By about three months, infants will make clumsy swipes at objects. Between four and six months, infants become more successful at grasping objects (Daum et al., 2013). Grasping is reflexive at first. Voluntary holding replaces reflexive grasping by three to four months.
