Psychologically based Virtual-Suspect for Interrogative Interview Training
This addresses training needs for law enforcement, but it is incremental as it builds on existing virtual training methods.
The paper tackles the problem of training law enforcement personnel in interrogation strategies by developing a Virtual-Suspect system that simulates suspect behavior based on psychological states and context, with experiments showing its behavior is similar to a human suspect.
In this paper, we present a Virtual-Suspect system which can be used to train inexperienced law enforcement personnel in interrogation strategies. The system supports different scenario configurations based on historical data. The responses presented by the Virtual-Suspect are selected based on the psychological state of the suspect, which can be configured as well. Furthermore, each interrogator's statement affects the Virtual-Suspect's current psychological state, which may lead the interrogation in different directions. In addition, the model takes into account the context in which the statements are made. Experiments with 24 subjects demonstrate that the Virtual-Suspect's behavior is similar to that of a human who plays the role of the suspect.
