Document Summary

Pozzulo, bennel & forth forensic psychology, 4th edition pearson. Day, forensic psychology handbook mcmaster custom courseware, 2014. Most heard about forensic psychology through the media. Forensic: comes from latin word forensis- of the forum (of the law) Meteorology (what was the weather like at the time of the crime?) Lots of things to do with forensics are judgment calls. Eg: fingerprints- if they look the same. Hair/fiber samples- if they are the same. *44 bce: first forensic autopsy conducted on julius caesar by roman physician antistius (stab wounds) *1921: californian john larsen develops first practical polygraph. Polygraph is not a lie detector- used for multiple measurements. *1924: la, california, establishes first us crime laboratory. *1974: first use of scanning electron microscope to detect gunshot residue (gsr) *1984: in england, sir alec jeffries develops restriction fragment length polymorphism for dna fingerprinting . *1986: polymerase chain reaction (pcr) for dna replication developed.
