FASTER MEANS BETTER? Three Studies of Musical Tempo Jeffrey M. Miller Blaine Peden, PhD. Lee Anna Rasar, MMEd. Mickey Crothers, PhD. University of Wisconsin – Eau Claire

Why may the results be inconsistent? Lack of statistical analysis in some studies Corporative motives Low sample sizes Subjective labels to categorize mood Failure to manipulate tempo
STUDIES MANIPULATING TEMPO Martin1990no significant differences in slow, medium, or fast tempo for simple or complex task Gunsch1991rock music improves math scores more than instrumental or no music
Experiment #1 Effects of Tempo on Typing Test Measures of Speed and Accuracy Jeffrey M. Miller Lee Anna Rasar, MMEd. Mickey Crothers, PhD. Funded by the McNair Program July – August, 2000
3 X 4 Mixed Design Between Subjects: 3 Groups Within Subjects: 4 Rounds #1: Practice - Slow – Medium – Fast (n=16) #2: Practice - Fast – Medium – Slow (n=17) #3: No music during any round (n=16) Dependent Variable 1: Typing Speed Dependent Variable 2: Typing Accuracy

Conclusions Music may distract from productivity regardless of aesthetic enjoyment.
What if the tempo changes within the piece of music?? Was music distracting because the typing test was complex??? Let’s try a math test!
Experiment #2: Tempo Direction and Text Consistency Implications for Test-Taking Jeffrey M. Miller Blaine Peden, Ph.D. Course Requirement August, 2000
2 X 2 Factorial Design Between Subjects Variable 1: Tempo Acceleration or Tempo Deceleration Between Subjects Variable 2: Consistent Font or Inconsistent Font Dependent Variable 1: Math Problems Completed Dependent Variable 2: Math Accuracy
Source ppartial n 2 Tempo < Font = Tempo x Font= Math Problems Completed
Source ppartial n 2 Tempo < Font n.s Tempo x Font n.s Math Problems Correctly Solved
Conclusion Conclusion Accelerating tempos promote higher rates of math completion and accuracy. Alternatively, The accelerating tempo was less readily perceived, and, hence, less distracting
What if some math problems are simple and some are complex? What if some math problems are simple and some are complex? What if the tempo changes between groups? What if we use music by a different composer?
Experiment #3: Complexity and Range of Modulation: Factors in Tempo Perception Jeffrey M. Miller Blaine Peden, Ph.D. Funded by University of Wisconsin – Eau Claire February, 2001
3 X 2 Mixed Design Between Subjects: 3 Groups Within Subjects: 2 Rounds #1: No tempo increase #2: Tempo increase of 25% #3: Tempo increase of 50%
Source ppartial n 2 Tempo < Complexity < Tempo x Complexity< Math Problems Completed
Source ppartial n 2 Tempo n.s. --- Complexity < Tempo x Complexityn.s. --- Math Problem Errors
Conclusion Faster tempos decrease math completion regardless of test complexity ANOTHER VARIABLE!!! Melodic Activity

FUTURE DIRECTIONS Typing Study: Replication in the Workplace Math and Complexity Studies 1. Include 25% and 50% SLOWER hypothesizing that scores increase for simple problems at slower tempos. 2. Compare the Bach and Haydn pieces hypothesizing that the Haydn piece promotes higher scores at different levels of tempo increase due to differences in melodic activity.
