This is a video describing the Virtual Bomb Detection Task which is a behavioral risk-taking task. I have built this task as part of a larger experiment I am currently running. Essentially, with this task participants are conditioned to discriminate an appropriate exit time based on the arbitrary symbol that is displayed on the screen. In essence, the symbol becomes a conditioned threat stimuli because it discriminates between avoidance and approach behaviors in the virtual environment. In relation to the larger experiment, I am testing if the conditioned threat symbol affects pain perception when pain accompanies the symbol in a later part of the experiment.
If you are interested in the task, how it was built, or anything else please don’t be shy in shooting me an email—I love talking about this stuff.
Subject Trial Visualization
- Boxes represent boxes in the room (red=damage, green = safe)
- DI = damage index (Number of damage boxes*damage per box/total number of boxes)
- Player path is represented by the line traversing the plot (green = safe symbol, blue = safe symbol #2, red = threat symbol).
- Size of each point is a function of the relative head movement on a given trial (larger = increased head movement at that point).
- Numbers and letters around the outside of the plot represent absolute degrees and cardinal directions of orientation for the subject.
