Above is the link to an incredibly large listing of common vocabulary terms used in the forensic sciences. I've found it useful when reading journal articles, or adding in relevant terms ot a blog posting, etc. 

            For example, criminals get more and more upset and emotionally frustrated when thinking about jail-time, in particular a longer jail sentence.  This is known as inmate reactance, which is the increased negativity experienced when an inmate has his personal freedom threatened.   Serial killers often have call signs, or specific rituals, or behaviors that they emit at each crime scene indicating that they are the ones responsible.  This is often highlighted in movies about serial killers like Seven, Silence of the Lambs, etc.  We could say that each of these serial killers has a unique personation which indicates they are responsible; personation is the term for these ritualistic behaviors such as "body positioning (of the victim), mutilation, or other symbolic gestures."

This is another site which has vocabulary more specific to forensic psychology.  This website has longer descriptions for each word which can be helpful.  Although many of the words are basic psychology terms that don't always have a direct relevance to forensics.

            Some more highlights include:

Ecomania-       pathological attitude directed towards one's family

Familicide-      when an individual kills his/her spouse and one or more children

Frottage-         sexual gratification achieved by rubbing against the clothing of a member of the                            opposite sex in a crowd.
