Computer Game Play Reduces Intrusive Memories of Experimental Trauma via Reconsolidation-Update Mechanisms.

James EL, Bonsall MB, Hoppitt L, Tunbridge EM, Geddes JR, Milton AL, Holmes EA - Psychol Sci (2015)

Bottom Line: Memory of a traumatic event becomes consolidated within hours.Intrusive memories can then flash back repeatedly into the mind's eye and cause distress.A simple, noninvasive cognitive-task procedure administered after emotional memory has already consolidated (i.e., > 24 hours after exposure to experimental trauma) may prevent the recurrence of intrusive memories of those emotional events.

Results of the time-series analysis in Experiment 2: Poisson distribution of the predicted likelihood of intrusive memories in the combined control group (no-task control, Tetris only, and reactivation only; top row) and the reactivation-plus-Tetris group (bottom row), separately for Day 0, Day 1, and Day 2.

Mentions: From nonlinear time-series analysis, expected Poisson distributions revealed that by Day 2 (24 hr after intervention), the expected probabilities of no intrusive memories for participants in the reactivation-plus-Tetris group (almost completely centered on 100% likelihood of zero intrusive memories) was greater than that predicted for the combined control group (Fig. 6). Thus, a memory-reactivation task for a trauma film (24 hr postfilm) followed by Tetris reduced intrusion frequency in the following week if, and only if, game play occurred in combination with the memory reactivation (i.e., consistent with the hypothesis that the combined procedure interfered with intrusive memory reconsolidation).
