We investigated expectations regarding a writer's responsibility to proofread text for spelling errors when using a word processor. Undergraduate students read an essay and completed a questionnaire regarding their perceptions of the author and the quality of the essay. They then manipulated type of spelling error (no error, homophone error, non-homophone error) and information provided about the author's use of a spell checker (no information, author did not use a spell checker, author did use a spell checker). Participants' perceptions of the author's abilities and the quality of the essay suffered when the essay contained non-homophone spelling errors--errors that are typically flagged by a spell checker. Further, participants reported that they would be most likely to blame the writer rather than the spell checker for spelling errors contained in the text. These findings suggest that perceptions of both an author's abilities and the written products are affected by spelling errors. Even when supportive tools are available, the responsibility for producing error-free text remains with the author.
