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 from Experiment 2: mean number of intrusive memories recorded in the diary during the first 24 hr following viewing of the experimental trauma film (i.e., preintervention; a), mean number of intrusive memories recorded in the diary across totaled over the 7-day period after the intervention (b), and mean score on the intrusion-provocation task on Day 7 (c). In each graph, results are shown separately for the four groups. Asterisks indicate that results for the reactivation-plus-Tetris group were significantly different from results for the other three groups (*p < .01). Error bars represent +1 SEM.

Mentions: First, prior to the intervention (over the first 24 hr after viewing the film: Day 0), we confirmed that the four groups experienced a similar number of intrusive memories, F(3, 68) = 0.16, p = .92 (Fig. 4a).
