Abstract
Advancements in the measurement of intellectual functioning via individually administered intelligence tests during the early 1900s led to reliance on IQs to represent the deficits in intellectual functioning during the past century. Concurrent development of models of intelligence also advanced understanding and measurement of intellectual functioning, and the current consensus is that intellectual functioning is best represented by a latent ability referred to as general intelligence (or psychometric g), as well as numerous broad and narrow abilities. As a result of these developments, the practice of identification of persons with intellectual disability (ID) is now based on a stronger scientific foundation. This chapter discusses three models of intelligence and reviews the genetic and environmental influences on intellectual functioning across the population, and persons with ID in particular. It culminates with a description of best practices and emerging methods in the assessment of intellectual functioning. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
