The importance of validity and reliability in the componential analysis of human intelligence is discussed. The roles of construct, internal, external, convergent, discriminant, and ecological validity in componential analysis are outlined. Within-replication (internal-consistency) and between-replication (alternate-forms or test-retest)…

Although there seems to be widespread agreement that new approaches to studying intelligence should combine the differential and cognitive (information processing) approaches in isolating components of intelligence, researchers disagree about how the approaches should be combined and, consequently, about how elementary components of intelligence…

An information-processing analysis of intelligence proposed by Eysenck and Furneaux was examined in an experimental study of semantic categorization and free recall by 11-year-old children of varying intelligence. Results, and implications of the results, are discussed. (Author/KC)
