Interval timing performance and frontal theta power do not differ as a function of bipolar disorder sub-type. A Schematic diagram of supra-second interval timing task. Trials begin when participants are shown a 3 s or a 12 s timing cue. Participants press a button to indicate their estimation of the target interval. B Response distribution for individuals with bipolar I or bipolar II disorder. C-D Groups do not differ in time estimation for the short [C] or the long [D] intervals. E Frontal theta power during the ITT did not differ between groups. Mean and standard error of the mean plotted in bar graphs. Dots represent values from individual subjects. *p < 0.05
