This study replicated and extended Kranzler and Jensen's [Intelligence 13 (1989) 329] metaanalysis 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.
