This feasibility study aims to adapt a protocol usually run in the laboratory in the Psychology Department for healthy participants (including the trauma film paradigm (James et al., 2016) and a simple cognitive task intervention) to remote (online) delivery. The motivation for this was restrictions to running in person laboratory experiments during the COVID-19 pandemic. Participants will view film footage with COVID-19 related and potentially traumatic content (e.g. of seriously ill or dying patients in hospitals). Following film viewing, participants will be randomly allocated to either the experimental condition (simple cognitive task intervention, i.e. a memory cue followed by playing the computer game "Tetris" with mental rotation instructions) or the control condition (attention placebo, i.e., a memory cue followed by listening to a podcast for a similar duration). Any intrusive memories induced by the film (analogue trauma) will be monitored in a daily diary. It is predicted that the film (analogue trauma) will generate intrusive memories. If intrusive memories are generated, then it is predicted that participants in the experimental condition will report fewer intrusive memories related to the film (analogue trauma) during the following week than participants in the control condition. The development of this paradigm may inform the future development of a simple technique to prevent intrusive memories e.g. after repeated media consumption related to the COVID-19 pandemic.
This is a between-groups experimental study with healthy participants informed by prior
laboratory work. It includes two sessions and a seven-day daily diary in between sessions. In
this feasibility study, for the first time all study procedures will be delivered remotely
rather than in a laboratory because of the COVID-19 pandemic. The primary outcome is the
number of intrusive memories related to the film (analogue trauma) recorded in a daily
electronic diary during the following week (week 1).
The first aim is to investigate if the film (analogue trauma) will generate intrusive
memories. The second aim is, if intrusive memories are generated, to investigate if
participants in the experimental condition will report fewer intrusive memories of the film
(analogue trauma) than participants in the control condition.
Behavioral: Simple cognitive task intervention
A memory cue followed by playing the computer game "Tetris" (on own smartphone) with mental rotation instructions for ca. 12 minutes.
Behavioral: Attention Placebo
A memory cue followed by listening to a podcast (on own smartphone) for ca. 12 minutes.
