Research examining infants' sitting skills and their 3D object completion skills suggests that
A) there is overlap in the brain maturation required for each of these skills.
B) 3D object completion is necessary for skilled sitting.
C) there is a great deal of interaction between visual development and motor development.
D) there are specific brain regions devoted to each of these skills.

Question

Quizplus · Accepted Answer

The research suggests that there is a great deal of interaction between visual development (as in 3D object completion) and motor development (as in sitting skills). There is likely overlap in brain maturation required for each of these skills, but the research does not make a specific statement about this. The research does not suggest that 3D object completion is necessary for skilled sitting, and while there may be specific brain regions involved in each of these skills, the research does not make this claim.
