Question

Quizplus · Accepted Answer

Both intellectual disability and high IQ reflect extreme positions on the normal curve of cognitive ability. Intellectual disability is defined as having an IQ score of 70 or below, while being mentally gifted is generally defined as having an IQ score of 130 or above. Both of these conditions represent the minority of individuals with regard to cognitive ability, with most individuals falling within the average range (i.e., 85-115). Neither condition requires culture-fair IQ tests to be demonstrated, as standard IQ tests are generally used to identify both conditions. Additionally, while early childhood experiences may play a role in the development of intellectual disability, high IQ is thought to be largely a product of genetics. Finally, both conditions can be influenced by environment, particularly in terms of the opportunities and supports provided to individuals with these conditions.
