It addresses two issues related to the validity of verbal reportsreactivity and veridicalityand reviews studies that have examined the validity of verbal reports in SLA. On the basis of the results of a meta-analysis of studies comparing the performance of silent and think-aloud groups (Bowles, 2010), this article concludes with suggestions for further research into the issue of validity and recommendations for the careful use of think-alouds in research.
