Raine concludes that findings from animal studies into aggression can be generalised to humans and there is a link between brain structure and aggression.
What sampling method did Raine use?
British Psychologist Adrian Raine is a criminologist who specializes in studies investigating biological correlates of criminal behaviour. In a study conducted in 1997, Raine used PET scans to compare the brains of two groups: Convicted murderers who had pleaded not guilty by reason of insanity (NGRI), Non-murderers.
What was the aim of Raine et al study?
You can also find all of the past exam questions on Raine’s study here. There are many web sites showing good images of PET scans. Here is one. The aim of the experiment was to discover if murderers who have pleaded not guilty by reason of insanity (NGRI) show evidence of brain abnormalities.
What type of experimental design did Raine use?
Method and Design The experiment is considered quasi because the experimenters could not manipulate the independent variable as it was naturally occurring; a person was a murderer, or they were not a murderer. The study used a matched participants design.
Who did Raine study?
They were always fun. They were always interesting, and I was fascinated most of all with how they could con and manipulate me.” Adrian Raine has studied the brains of violent criminals, including that of serial killer Randy Kraft, aka the “Freeway Killer.” “In the ’70s, ’80s and ’90s, violence went up in America.
What were the three areas of the brain that Raine found differences in glucose metabolism in between murderers and controls?
Positron emission tomography (PET) brain imaging was conducted on 41 murderers pleading NGRI and 41 control subjects. Murderers were characterised by reduced glucose metabolism in the prefrontal cortex, superior parietal gyrus, left angular gyrus, and the corpus callosum.
What is the biological approach in psychology?
The biological perspective is a way of looking at psychological issues by studying the physical basis for animal and human behavior. It is one of the major perspectives in psychology and involves such things as studying the brain, immune system, nervous system, and genetics.
What did Raine?
Adrian Raine was the first person to conduct a brain imaging study on murderers and has since continued to study the brains of violent criminals and psychopaths.
What is low ecological validity?
Ecological validity refers to the ability to generalize study findings to real-world settings. Low ecological validity means you cannot generalize your findings to real-life situations.
What is the condition of neurophysiology to crime?
Lombroso’s theory was that crime originated in part from abnormal brain physiology and that violent criminals where throwbacks to less evolved human types identifiable by ape-like physical characteristics. Criminals, he believed, could be identified by physical traits, such as a large jaw and sloping forehead.
Can genes and brain abnormalities create killers?
Breakthroughs in neuroscience are changing the way criminals are defended in court. Scientific research on brain scans and DNA has provided new insight on how some kinds of criminals are different from law-abiding citizens.
What does the amygdala do?
The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
What is the Raine et al study?
Raine et al,. (2002) – ‘Prefrontal Structural and Functional Deficits in Schizotypal Personality Disorder’. Background. Phineas Gage. Raine (1997) This study was conducted on convicted murderers, all of whom plead not guilty by reason of insanity. All of the murderers were brain scanned and compared with a control group.
Why should I take the Hesi A2 practice test?
A practice test will also reveal any areas that need further study and understanding. To ensure the most effective use of your time, take the HESI A2 practice test for the first time and indicate next to each question which of the following statements is true.
Who is Adrian Raine and what does he do?
British Psychologist Adrian Raine is a criminologist who specializes in studies investigating biological correlates of criminal behaviour. In a study conducted in 1997, Raine used PET scans to compare the brains of two groups: Convicted murderers who had pleaded not guilty by reason of insanity (NGRI),
What is Raine’s hypothesis about the brain?
Because of its role in emotion and behaviour regulation and control, Raine hypothesized that there would be significant differences in the brain activity in the prefrontal cortex (i.e. the murderers would have lower activity in their PFC) and this is indeed what he discovered.
