Which item is NOT listed as an environmental factor influencing intelligence?

• A. Cultural environment
• B. Genetics
• C. Exposure to toxins
• D. Family influence

Answer: (B)

Environmental factors influencing intelligence are aspects of a person’s surroundings that shape cognitive development. Cultural environment matters through schooling, expectations, and social norms that guide learning. Exposure to toxins can harm development, illustrating how physical surroundings affect cognition. Family influence includes parenting practices, home stimulation, and available resources that support or hinder intellectual growth. Genetics, on the other hand, refers to inherited biological factors that set potential but are not environmental. Since the question asks for what is not an environmental factor, genetics is the best choice because it describes a biological, not environmental, influence.
