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: Intrusive memories can then flash back repeatedly into the mind's eye and cause distress.We investigated whether reconsolidation-the process during which memories become malleable when recalled-can be blocked using a cognitive task and whether such an approach can reduce these unbidden intrusions.Furthermore, both memory reactivation and playing Tetris were required to reduce subsequent intrusions (Experiment 2), consistent with reconsolidation-update mechanisms.

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).
