Abstract

Inspection time (IT) has been shown to correlate reliably with putative tests of general intelligence such as Raven's matrices and more strongly with performance IQ than with verbal IQ from the Wechsler scales. A common interpretation of this pattern has been that PIQ and matrices tests are measures of fluid ability (Gf) and therefore that IT provides an index of a biological substrate underpinning individual differences in IQ. Marker tests for five of the constructs described in Gf-Gc theory of cognitive abilities were administered to a sample of 64 adults who also completed IT estimation. IT correlated -0.43 (p<0.001) with a test of general processing speed (Gs) but did not significantly correlate with a test of Gf. Results of partial cor...
