Question

Quizplus · Accepted Answer

The concept of reaction range suggests that individuals with a specific genetic makeup have a range of potential outcomes depending on the environmental factors they experience. In this case, an individual with genes for lower IQ may reach a higher level of intelligence in an enriched environment, which is an example of the reaction range concept. Choice A is incorrect because the reaction range theory suggests that environment can have an impact across the entire distribution of intelligence scores. Choice C is incorrect because this describes a new test being developed, which is unrelated to the concept of reaction range. Choice D is incorrect because there is no specific level of intelligence that can be attributed solely to genetics.
