Resumen:

This study set out to investigate the relationship between L2 vocabulary knowledge (VK) and second-language (L2) reading/listening comprehension. More than 100 individual studies were included in this meta-analysis, which generated 276 effect sizes from a sample of almost 21,000 learners. The current meta-analysis had several major findings. First, the overall correlation between VK and L2 reading comprehension was .57 ( p .01) and that between VK and L2 listening was .56 ( p .01). If the attenuation effect due to reliability of measures was taken into consideration, the ‘true’ correlation between VK and L2 reading/listening comprehension may likely fall within the range of .56–.67, accounting for 31%–45% variance in L2 comprehension. Second, all three mastery levels of form–meaning knowledge (meaning recognition, meaning recall,...
