Neuroanatomical correlates of straight driving

excel spreadsheet containing study data:&gt; tab "behav" contains behavioural measures, appended with either "str" (straight driving) or "straud" (straight driving with auditory distraction). The include: mean_speed (average speed), sd_speed (standard deviation speed), mean_acceleration (average acceleration), sd_acceleration (standard deviation acceleration), mean_lanepos (average lane position), sd_lanepos (standard deviation lane position), mean_headingang (average heading angle), sd_headingang (standard deviation heading angle), sum_crashes__full (total numer of crashes - all conditions), percent_time_speeding_s (percent time spent speeding), percent_time_offcenter_s (percent time off-center), sum_btp_correct (sum correct responses). For behavioural contrasts in the paper ("audcontrast" analyses in the appendix), they are generated by subtracting "straud" from "str" for the behavioural measure of interest.&gt; tab "gm" gives grey matter measures, pre-pended with either "rh" or "lh" corresponding to left and right hemispheres, and appended with either "volume" or "thickness". Regions include: caudalmiddlefrontal, inferiorparietal, precentral, rostralmiddlefrontal, superiorparietal, superiortemporal, along with left and right Cerebellum.Cortex, and intracranial volume estimate eTIV.x. For the study, grey matter values are obtained by summing left and right measures; we further combine subregions as: middlefrontal = caudalmiddlefrontal+rostralmiddlefrontal and posteriorparietal = inferiorparietal+superiorparietal.&gt; tab "demo" gives the age and sex of each participant.<br><br><br><br>
