Discuss the reliability of this procedure.
Discussion points could include:
· Some participants may show demand characteristics and others may not.
· Use of a computer generated environment increased reliability e.g. all participants were on exactly the same 4 min journey on the same 4 min train ride.
· The avatars responded differently to the participant depending on how the participant acted in the VR simulation e.g. if the participant looked at one of the avatars the avatar would smile at them. This means each participant had a different experience of engaging with the avatars which lowers the reliability.
· Some participants may respond more to the fact this isn’t their natural environment due to the type of schizophrenia they have, whereas others may not be affected by it at all. This shows how the scenario could impact on the participants in a different way and lower reliability.
