Final answer:
Heredity and environment work together in intellectual development. Genetics determines the level of intelligence, while the environment provides stimulation for cognitive abilities. The Range of Reaction theory explains how individuals with different genetic potentials can reach their full intellectual potential based on environmental stimulation.
Step-by-step explanation:
Heredity and environment work together in intellectual development. Genetics plays a role in determining the level of intelligence that a person has, while the environment provides the necessary stimulation for the expression of cognitive abilities.
The Range of Reaction theory suggests that individuals with different genetic potentials can reach their full intellectual potential depending on the environmental stimulation they experience. For example, a child with average genetic potential raised in a stimulating environment is likely to have improved intellectual outcomes.
