What do such developmental milestones as crawling, walking, and so forth tell us about potential biological or cultural constraints on the development of learning?
A) They suggest that biological constraints do little to learning, because the timing of the milestones varies greatly from infant to infant.
B) They suggest that biological constraints guide learning, because the timing of the milestones is similar from infant to infant.
C) They suggest that cultural constraints guide learning, because the timing of the milestones is similar from infant to infant.
D) They suggest that cultural constraints guide learning, because the timing of the milestones varies from culture to culture.

Question

Quizplus · Accepted Answer

The fact that crawling and walking are developmental milestones that occur at similar ages across different infants suggests that there are biological constraints guiding the development of these skills. This suggests that learning is also guided by biological factors. Cultural influences may play a role in how these skills are learned and valued, but they do not appear to be the primary driving force behind the development of crawling and walking.
