Laboratory findings – Single approx 25-min behavioural intervention (reminder + filler + mental rotation instructions for Tetris game play) 24 hours after trauma: tested after experimental trauma but not real-world trauma. Main outcome is reduction of intrusive memories over 1 week. Neither game play alone not trauma reminder cue alone was sufficinet: full intervention package is needed.
Clinical findings showed that a single session of approx. 25 minute behavioural intervention (reminder cue + mental rotation instructions + Tetris game play) reduce intrusive memories of trauma over one week (Yiadurai, 2018, Horsch, 2017). Idealy it should be applied before the first night of sleep after the exposure. Longer term studies needed.
