|
What kind of study did Mednick et al do? |
An adoption study |
|
|
What data did Mednick et al use? |
Criminal records |
|
|
What was the sample in Mednicks study? |
14k Danish males born between 1924 and 1947 |
|
|
What did Mednicks study find? |
That biological parents had the most impact and thus the bio theory is supported. |
|
|
Name some role models for criminal behaviour |
Parent Peer Media personality |
|
|
Give an example of how behaviour may be vicariously reinforced? |
A mugger may get away with someone’s handbag, a bank robber is rewarded with money, a shoplifter gets sweets, etc |
|
|
What facial features are related with criminal behaviour? |
Crooked nose, strong jaw, large ears, fleshy lips, asymmetrical face, glassy eyes, high cheek bones, big protruding ears, hairy mofo |
|
|
How is heritability associated with criminal behaviour? |
It means that there is a gene for criminal behaviour (1) which is inherited from parents (1) |
|
|
What is the job of the pre-frontal cortex and what happens if its messed up? |
It's where fear is created and if it's under active then criminals aren't scared of consequences |
|
|
What is the job of the Limbic System and what happens if its messed up? |
Controls aggressive and sexual behaviour and if it's over active then psychopaths with commit violent crimes like rape or assault. |
|
|
What is the job of the Corpus Callosum and what happens if its messed up? |
Links the rational and irrational side of the brain (think Bo Burnham Left VS Right brain!) and if it's under active then murderers have irrational thoughts. |
|
|
What is the job of the Temporal Lobe and what happens if its messed up? |
Many important functions. If it has slower brain wave activity then psychopaths won't think about consequences. |
|
|
What are the criticisms of the biological theory? |
-There can't be ONE GENE for ALL behaviours, like tax fraud versus serial rape??? nah man -Brain dysfunction is only present in some criminals -Different features concept is not supported by much evidence -Ignores influence of sociality |
|
|
Why is crime hard to define? |
Some crimes are crimes in one place but legal in another. Can you really call a rapist and a shoplifter the same kind of 'criminal'? NAH MAN! |
|
|
What does the biological theory argue? |
That criminal behaviour is a genetic thing, that we inherit (heritability) a gene of criminality. Also that brains of criminals are abnormal in some way, referred to as brain dysfunctions. |
|
|
What is the basis of the social learning theory? |
We learn behaviours from observing and imitating others. Also, vicarious reinforcement. |
|
|
What is vicarious reinforcement? |
You see someone doing a thing and reaping the reward or consequence of it and are thus motivated for or against doing that thing. |
|
|
An example of vicarious reinforcement? |
A little boy named Terry sees his father beating up another man and being applauded for it and respected, he then goes and starts beating up other children to get the same rewards. |
|
|
What was the procedure of Mednick's study? |
Looked at the criminal records of 14k Danish males and compared them with the records of these men's biological and adoptive parents' records. |
|
|
Percentage wise, how many more kids committed crime when their biological parents had VS their adoptive parents (how tf am i supposed to words this hhelp i cant english) |
14.7% vs 20% |
|
|
You're doing great! |
|
|
|
What are the limitations of Mednick's study? |
-Criminal records aren't always reliable, there's false accusations and also unrecorded crimes that never went on record -Contamination effect: pre- adoption, kids could have already been influenced by bio parents -Sample was biased, only males |
|
|
How does research into Criminal Behaviour impact our crime reduction efforts? |
Using the social learning theory, crime can be reduced by making media presence (role models) less...bad. This can be age restrictions, bans, etc. Just anything to stop young, easily influenced kids from learning that shooting people is good because you get dolla. Intervention programmes enforce good behaviour and shoot down bad. Prisons put people off, so we crack down on crime. |

Go drink some water, please. |
