What information should a forensic physiologist know before interviewing someone?

A forensic physiologist? Do you mean a Forensic Psychologist? the ones that I have dealt with want to know as much information as they can. I have even seen some give a pre-interview questionnaire. I'm curious why he is meeting with one? The interview can take hours, but they will cut the time back if they see someone getting stressed or believe the answers are being falsified. They like to review their notes extensively, so I'm not sure on how long for "results".
