Affect of anxiety on EWT Evaluation continued...
Control settings lack validity: because of the controlled, artificial environment it is impossible to recreate the exact conditions (shock, surprise, fear etc) of a real EWT for practical & ethical reasons.
Therefore the settings may lack validity and in turn invalidate the findings.
***
Ethical reasons: Psychologists can't induce unnecessary psychological harm and must gain informed consent from participants. However as anxiety is a key component of EWT unless occuring naturally, must be induced by the researcher E.G. by watching a video. This may cause psychological harm especially for young children.
Therefore much research in this area may be questionable ethically.
