The relationship between age, IQ test scores and inspection time (IT) was investigated, comparing children from two age groups (6–8 and 10–12 years) and three IQ levels (low, average, above average). The results indicated a reliable estimate of IT could be obtained from all groups, even across two procedures. IT was found to improve with childhood maturation among children with average and above average IQ. Correlational analyses indicated that, within this age range, IT was more related to mental age than to IQ. Results are discussed in terms of a model in which a minimum processing speed is essential for, but not alone in contributing to, IQ.
