Mothers Driving Game: Self Driving and Observing Child Driving

Description: Twenty-three healthy mothers (Mage = 44.61 yrs, SD = 6.81, range: 32 - 64) and their child (Mage = 13.83 yrs, SD = 0.49, range: 13 - 14) were recruited to participate in this study. Mothers and children underwent fMRI scans on the same day but children’s scan happened in advance to their mothers scan.During the fMRI scan, mothers completed two runs of the Stoplight task, named ‘driving run’ and ‘observation run’. The driving run was to collect mothers’ neural activity when they are actively performing the Stoplight task whereas the observation run was to assess mothers’ neural response while they were observing their child’s Stoplight task playing. During the observation run, mothers were thus presented to the video recording of their child’s Stoplight task and asked to view it passively. For the observation run, each mother’s child played the Stoplight task in the scanner in advance to his/her mother’s scan session, and we videotaped the screen of their stoplight playing. In this archive, we prepared unthresholded contrast map (z-value) for 1. main effects of run (Observation vs. Driving) for each outcome (Pass, Wait, Crash) 2. run-by-outcome interaction effects: [ Observation (Wait - Pass) – Driving (Wait - Pass) ] [ Observation (Crash - Pass) – Driving (Crash - Pass) ] [ Observation (Crash - Wait) – Driving (Crash - Wait) ] 3. Observation run focused: [ Crash - Pass ] [ Crash - Wait ] [ Wait - Pass] 4. Anticipation responses for child's outcomes during the Observation run.
