Gerald is an intellectually gifted child with an extensive vocabulary. He is emotionally mature and physically developed. Gerald's development in each of the three domains is best explained by which of Baltes' developmental ideas?

Answer: Development is multidimensional

Explanation:

Paul B. Baltes (1939 - 2006) was one of the most prominent developmental psychologists. Baltes' multidimensionality refers to the intricate interaction of elements, either endogenous or exogenous, that shapes development throughout the lifespan. This means that specific factors have the strongest effects on certain domains, but there isn't a single element determining the development of a domain.
