A Unified Cognitive/Differential Approach to Human Intelligence: Implications for IQ Testing

We present process overlap theory, a new theory of intelligence that is informed by cognitive psychology. The theory explains the positive correlations between diverse tests on the basis of overlapping cognitive processes and reinterprets the general factor of intelligence, g, as a formative construct. The consequences of this approach are discussed, including a focus on specific abilities rather than on global scores in cognitive test results.
