Research Tools - Two-Stage
Cued Recall Debrief
 |
We
have developed a number of products and systems we use in our research.
The two main data-gathering platforms are the Networked Fire
Chief microworld software and the Head-Mounted Video
system used for capturing events from the first-person perspective
of the participant.
The supporting techniques for enhancing the data are the Two-Stage
Cued Recall Debrief and the Video-Based Eye Tracking.
A purpose built usability / simulation laboratory
has been designed for use when required. |

In
debriefing subjects while they view a replay of a previous decision
episode, whether generated by a head-mounted video camera or by
computer simulation, we have found that the accuracy and comprehensiveness
of the recalled material is greatly enhanced from being cued by
this 'own-point-of-view' replay. We have found that it is most effective
if a two-stage debriefing
procedure is adopted. |

The first stage involves
the participant taking an insider perspective, using the replay as
a stimulus to relive all mental events (e.g. thoughts, choices, uncertainties,
feelings) which occurred, uncensored for relevance or appropriateness.
The participants recollections are recorded using a small microphone
and combined with the original video footage onto a second video tape.
The second stage involves
the subject taking an outsider perspective in viewing the replay while
simultaneously listening to the recollections recorded in the first
stage. During this second review the interviewer can ask focused questions
aimed at tapping the more fundamental psychological processes.
This procedure solves the process tracing problems which are inherent
in the study of dynamic environments. It allows the gathering of valid
and reliable reports on participants' own experiences.
The procedure is equally well suited for use with video and computer
simulation replays. |
