Reactivation + Tetris: These participants were shown a series of images from the trauma film to reactivate the traumatic memories (i.e., reactivation task).No-task control: These participants completed a 10-minute music filler task.The experimenters randomly assigned participants to ONE of the following conditions: Because this is before the experimental manipulations, all groups were predicted to have an equal occurrence of intrusive memories during the first 24-hours (called Day 0).Įxperimental Task: After this 24-hour period, the participants returned to the lab and completed the experimental task. Participants then went home and recorded the number of intrusive memories they experienced over the next 24 hours. Trauma Film: All participants viewed a series of video clips of graphic violence (e.g., a person getting hit by a van while using his phone as he crosses the road) as a way to create memories that should become intrusive memories. To test their hypothesis, the authors conducted an experiment ( N = 72, n = 18 per condition). In other words, if you play Tetris shortly after you were remembering bad memories, playing Tetris might weaken those memories, which could cause you experience those kinds of intrusive memories less often in the future. In comparison, simply completing a visuo-spatial task (without reactivation) or reactivation (without a visuo-spatial task), would not reduce the occurrence intrusive memories. They hypothesized that only participants who complete a visuo-spatial task after reactivation of the traumatic memories would experience a reduction in intrusive memories. For example, some research shows that traumatic memories can be altered and weakened to the point that they are no longer intrusive.īecause intrusive memories of trauma are often visual in nature, James and colleagues (2015) sought to explore whether completing a visuospatial task (e.g., Tetris) after a memory was formed would interfere with the storage of that memory, and thereby reduce the frequency of subsequent intrusions. Instead, previous research suggests that a better approach may be to try to change aspects of the memory after it is formed. Although people often try to simply forget traumatic memories, this approach is not very effective. 11.4.2 Conduct a Mixed-Factorial Analysis of Variance (ANOVA)įollowing traumatic experiences, some people have flashbacks, which are also called “intrusive memories”" and are characterized by involuntary images of aspects of the traumatic event.11.1 Do you remember things better when you take pictures of them?.10.4.3 Conduct a Repeated Measures Two-Factor Analysis of Variance (ANOVA).10.4.2 Conduct a Between-Subjects Two-Factor Analysis of Variance (ANOVA).10.1 Does standing up make you focus more?.9.4.2 Conduct a One-Factor Repeated Measures ANOVA.9.1 Betcha can’t type JHDBZKCO very fast on your first try.8.4.3 Unplanned Comparisons: Post-hoc tests.8.4.2 Performing a One-Factor Analysis of Variance (ANOVA) & Graphing the data.
