Studies of blind manuscript review have illustrated that readers often form impressions of or speculate about unknown authors' identities in the manuscript review task. In this article, the authors extend that work by examining the discursive and nondiscursive features that play a role in readers' active construction of author voice. Through a survey completed by 70 editorial board members of six journals in applied linguistics and rhetoric and composition, the authors identify quantitative and qualitative trends in reviewers' practices regarding voice construction. Findings indicate that many readers do build impressions of an author's identity when reviewing anonymous manuscripts and that the rhetorical nature of the review task may lead readers to attend more to some discursive features than to others.
