This study examined the usefulness of the "affect curve drawing method" as a sensory evaluation method for assessing changes in affect (excitation) in response to a stimulus over time. An evaluation sheet with the X-axis representing elapsed time and the Y-axis representing affect level on a scale of 0–100 points was used to plot affect changes every hour. Differences in the changes in the affect curves between high- and low-sensitivity participants in response to a stimulus, such as a wedding DVD, were investigated. The changes in the curves were larger for high-sensitivity participants than for the low-sensitivity group. These results suggest that the high-sensitivity group were excited while watching the DVD, while the low-sensitivity group watched it without large sensory alterations. These reaction tendencies corresponded with the results of an electrocardiogram analysis of the autonomic nervous system in which the heart rate variability of the high-sensitivity group was larger than that of the low-sensitivity group. These findings indicate that the affect curve drawing method is effective for time series evaluations of affect.
