The present study aimed to integrate evidence on the relationship among broad retrieval ability (Gr), processing speed (Gs), and divergent thinking (DT) with a three-level meta-analytic approach. The analysis was conducted on 560 effect sizes obtained from 47 studies with an overall sample of 10,391 participants. Results indicated moderate mean correlations for both the Gr–DT (r = 0.47, 95% CI: [0.38, 0.54]) and the Gs–DT relationship (r = 0.31, 95% CI: [0.20, 0.41]). Notably, the correlation between DT and Gr was significantly higher than between DT and Gs, and the former remained significant even after controlling for the Gr–Gs correlation (r = 0.35, 95% CI: [0.26, 0.44]). Moderation analyses revealed that the Gr–DT link was moderated by the modality of DT tests and type of DT indicator, whereas the Gs–DT link was moderated by the modality of DT tests and type of DT instruction. Overall, these findings support the claim on the essential role of broad retrieval ability and processing speed in creative idea production.

本研究旨在通过三级元分析方法整合广义检索能力 (Gr)、处理速度 (Gs) 和发散思维 (DT) 之间关系的证据。该分析是对从 47 项研究中获得的 560 个效应量进行的，总样本为 10,391 名参与者。结果表明 Gr-DT（r  = 0.47, 95% CI: [0.38, 0.54]）和 Gs-DT 关系（r  = 0.31, 95% CI: [0.20, 0.41]）具有中等平均相关性。值得注意的是，DT 和 Gr 之间的相关性明显高于 DT 和 Gs 之间的相关性，并且即使在控制 Gr-Gs 相关性后前者仍然显着（r = 0.35，95% 置信区间：[0.26，0.44]）。适度分析表明，Gr-DT 链接受 DT 测试方式和 DT 指标类型的调节，而 Gs-DT 链接受 DT 测试方式和 DT 指令类型的调节。总的来说，这些发现支持广泛检索能力和处理速度在创意产生中的重要作用。
