Flashcards in 1.1.4 Classic Research (Bi) Deck (22):
1

What did research show about rats who are stressed in early life?

They show increased activity in the right hemisphere when killing mice

2

What did severing the corpus callosum in rats lead to?

An increase in mice killing

3

What does the research on rats suggest?

The left hemisphere must have some role in controlling violent behaviour

4

What are the problems with linking the rat research to human brain dysfunction in murderers?

• extrapolating/generalising findings (rats aren't humans)
• rats aren't murdering - they kill instinctively

5

What did early research into brain dysfunction and violence in humans use?

• case studies of people with brain damage
• accidents - e.g phineas gage
• split brain patients

6

What is a split brain patient?

A patient who had had their corpus callosum severed, often as part of an operation designed to cure epilepsy

7

What do split brain patients show?

•Poor emotional expression
•Inability to grasp long term implications of a situation

8

Why might the effects of the split brain operation be linked to violence?

Split brain patients can't control their emotions (anger) and don't understand the consequences of violence

9

Other than the corpus callosum, what areas of the brain are linked to violence?

• temporal lobe
• frontal lobe
• the brain is also highly integrated so other areas can be involved

10

How have modern brain scanning techniques helped researchers in studying violent offenders?

Functional scans show brain activity in high levels of detail, so it is easier to study brain functioning amongst violent offenders

11

What has long been suspected about brain dysfunction?

Brain dysfunction can predispose someone to violent behaviour
