Become Serial Killers?

Areas Affected in the Brain

Common areas affected include the amygdala, temporal lobe, frontal lobe, and the limbic system

The damage of these parts of the brain tend to be due to either the way the person was brought up or a genetic flaw

Amygdala

Regulates emotions and motivation

Serial Killers have less control over their emotions

Differs from a regular brain because we have some control over emotions

A regular brain is able to suppress extreme feelings

Temporal Lobe

Processes sounds within brain

Bad childhood experiences that involve sound can lead to aggressive behaviour later on

Regular people may associate memories with sounds as well, but can control their emotions

Frontal Lobe

Regulates emotion, judgement, reasoning and voluntary movement

Also deals with processing emotions and speech

Has to do with serial killers feeling no remorse ( not feeling any guilt after doing harm to another human being)

Antisocial Personality Disorder- strongly related to psychopathy

Borderline Personality Disorder

Narcissistic Personality Disorder

Schizophrenia

Personality DisordersAssociated With Serial Killers

Case Study

Ted Bundy

A Brief History

Born to a young unwed mother and was raised by his grandparents who told him his mother was his sister.

Moved away with his mother when she remarried and had more children with her new husband.

He fell in love with a girl in university, fell into depression and dropped out of school when she broke up with him.

It was during this time that he found out the truth about his mother. He returned to school, earned a degree in psychology, and met another woman, becoming involved with her even after reuniting with his old lover.

After acquiring a steady job, Bundy began kidnapping and killing college-aged women.

Bundy continued to kidnap, rape, and murder young women for years; he was arrested in 1975 but escaped in 1977, only to be captured a week later but escape prison.

His rape and murders of college-aged girls continued until he was arrested in 1978 and finally executed in 1989.

A Brief History

Connecting the Case to the Brain

Life began with several common contributing factors to serial killers: a poor home life, an unusual upbringing, and a history of mental illness in his family. https://www.youtube.com/watch?v=Ksfa0AddkLM 9.29As a child, Bundy was shy and had few friends, and was interested in odd things.

As a teen he began watching people through their windows and stealing things.

Radical personality changes - depression after his breakup, and extreme bravado when he returned to school - as a child and teen he was isolated, shy, and self-doubting, but as a young adult he became confident and outgoing.

Connecting the Case to the Brain

Deficit in the frontal lobe, lack of emotion kept him from forming relationships and feeling remorse. http://abcnews.go.com/video/embed?id=11492907 2.56 Highly intelligent but most likely had Antisocial Personality Disorder and Psychopathy due to his inability to feel remorse, as well as his violent tendencies.

Killed in a pattern - each victim was a college-aged girl with long hair.
