, Introduction
Forensic psychology ≠ forensic science or law enforcement (no blood spatter analyst)
A (forensic) psychologist studies human behavior & tries to apply psychological principles to
assist legal system.
Forensic = “related to the law” (criminology & ?)
Intro (Ed Camber)
History
- Middle Ages and earlier: good and wrong related to religion, demons, witches,
sinners ...
- However: individual liability = you are responsible for your deeds
- End of Middle Ages: first use of ‘insanity’ (a person that’s not fully aware of his
deeds)
- 19th century: Lombroso: criminal atavism - Criminals → physical anomalies ex.
Thieves have expressive faces etc. it’s valuable, it’s a strange theory but by doing
this people can criticize this, that’s how science grows
- 19th century: development of theories around insanity and criminal behavior
- 1879: First laboratory for experimental psychology (W. Wundt)
- 1908: a book: ‘On the witness stand’ (Münsterberg) a series of essays to describe
research on eyewitness testimony, false confessions and uses of psychology in legal
problems
- 20th century: psychologists were more and more called upon to apply their
(rudimentary) knowledge to the legal system as expert (e.g., testifying as expert
witness) Psychology = a tool in arriving at fair and just legal outcomes
- Jenkins v. United States (1962): court ruled that psychological testimony could be
admitted to determine criminal responsibility (i.e., insanity) → Forensic psychologists
now routinely testify in insanity cases after evaluating defendants (being recognized
as an expert)
- Stanley Milgram Experiments (1961) the influence of a charismatic person or
someone with power
- Stanford Prison Experiment (1971) (the lucifer effect)
