Annotation	The argument that middle-aged adults are, on average, less intelligent than young adults is considered. 228 educated Americans aged 21 to 62 were given an array of tests focusing on a broad assessment of intelligence-as-knowledge, traditional estimates of fluid intelligence (Gf), and crystallised intelligence (Gc), personality, and interests. Compared with younger adults, middle-aged adults are more knowledgeable in many domains. A coherent pattern of ability, personality and interest relations is found. Results are consistent with a developmental perspective of intelligence that includes both traditional ability and non-ability determinants of intelligence during adulthood. A re-assessment of intelligence in adulthood is provided, in the context of a lifelong learning and investment model called PPIK, for intelligence as Process, Personality, Interests, and intelligence as Knowledge.
