Trying to mentally recreate an image of the situation
including details of the environment, such as the weather conditions
Recall from a changed perspective
e.g. describing what another witness would have seen.
Trying to mentally recreate the situation from different points of view
Recall in reverse order
The witness is asked to describe the scene in a different chronological order
e.g. from the end to the beginning.
