This study replicated and extended Kranzler and Jensen's [Intelligence 13 (1989) 329] meta-analysis of the relationship between inspection time (IT) and intelligence (IQ). Separate meta-analyses were conducted on obtained correlations (r's) between IT and general IQ for the total sample and for studies using samples of adults and children. Two new meta-analyses were also conducted. The first compared the IT-IQ r between visual and auditory IT; the second compared the r between strategy users and nonusers. For the total sample (N>4100), the r was -.51 after correction for artifactual effects (-.30 prior to correction). No statistically significant difference was observed between the mean corrected r of -.51 for adults and -.44 for children. The mean corrected r for visual and auditory IT measures were -.49 and -.58, respectively, suggesting that the relationship between IT and IQ is comparable across type of IT task. The mean corrected r of -.77 for strategy nonusers was statistically significantly higher than the r of -.60 for strategy users. Implications of these findings for future research are discussed.
