The relative importance of math‐ and music‐related cognitive and affective factors in predicting undergraduate music theory achievement

Based on research identifying relations between math and music, we aimed to identify the group of cognitive and affective factors related to math and music theory that best explained undergraduate music theory achievement. Using dominance analysis, we predicted the music theory course grades of 230 undergraduate music majors. Potential predictors were narrowed from measures of knowledge, aptitude, experience, confidence, and anxiety in both music theory and math as well as spatial skills and reading test scores. Results suggested that ACT math scores and music theory confidence were important predictors for Music Theories I and II grades. Music Theory I was also predicted by aptitude‐based music theory skills, and Music Theory II was also predicted by math course experience. These findings provide evidence for a relation between math and music theory and support the use of several readily available measures for college‐level music instructors to identify students who may struggle in music theory.     

Didn't You Run the Spell Checker? Effects of Type of Spelling Error and Use of a Spell Checker on Perceptions of the Author

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. We 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.
