a Illustration of refixation analysis in volumetric space. b The percentage of refixations out of total fixations in each condition. Each trial was separated into 30 s epochs relative to the time the interruption occurred. Double stars indicate significance (p < 0.01) for the within-subject comparison between interruption trials and the equivalent time period in control trials. Error bars denote the standard error of the mean. c Correlation between refixations in the 30 seconds following interruption and the overall time cost
