Figure 8.

Temporal plots (2000ms) of regression coefficients for the Speed X Sound term in the trial pupil diameter regression model. Beta (Speed X Sound) on the y-axis represents the effect of the interaction between response speed and the sound condition on trial pupil diameter, where a negative value indicates smaller positive correlation between Speed and trial pupil diameter in the Sound condition than the No Sound condition. Shaded areas represent the standard error of the mean. Time points with significant p-values at one-sample t-tests are marked in red. YA=Young Adults (in green); OA=Older Adults (in blue).
