Physiological Explanations

What was Lombroso’s theory on what makes a criminal?

Criminals are a subspecies of human and can be identified by features:
* narrow sloping brows
* large ears
* defined jawline
* extra fingers/ toes

Phsyiological Explanations

What was Sheldon’s idea of the criminal body, what type did he deem to be typically criminal?

Endomorphs, Mesomorphs and Ectomorphs
Mesomorphs most likely to be criminals- most common body type among criminals
Muscular builds may find they can achieve rewards more easily by using force rather than hard work (OC)
May prejudice others around them to treat them as criminal- can’t escape stigmas (SFF)

Non-physiological explanation

What are the two non-physiological behaviours?

Bandura- social learning theory
Trzesniewski- self esteem (Maslow’s Hierarchy)

Non-physiological explanation

How can social learning theory be applied to crime and reinforcement of criminal actions?

Child around role models who engage in crime (drug dealing) observes behaviour
Behaviour vicariously reinforced if it is seen to have good outcome (financial reward)
Children imitate in hope of good reward too, reinforcing behaviour

Non-physiological explanation

How can levels of self-esteem be applied to criminal behaviour?

Adolescents with low esteem are more likely to engage in criminal activity
Humanist explanation- low self esteem= failure to reach self-actualisation due to no access to external supportive sources

Raine

What was the aim of Raine’s research?

To study brain activity in murderers and non murderers using a PET scan to identify differences in areas that are thought to be involved with violent behaviour

Raine

What was the sample for Raine’s research?

41 murderers (39m, 2f) matched with 41 non-murderers by sex and age (6 by schizophrenia)
* Murderers pleaded not guilty by reasons of insanity (NGRI)

What is the definition of PET (positron emission tomography)?

Type of brain scan where patient is injected with radioactive ‘tracer’ and can be traced to see brain activity

Raine

Why did participants practice the CPT before the real thing?

To remove natural reaction and emotion like nerves or excitement, as they were trying it for the first time

What two techniques were used to identify and analyse brain regions?

Cortical Peel Technique- used for sides and surfaces of brain
Box technique- used for inside brain

Raine

What was found about the limbic system in murderers?

Asymmetrical activity (amygdala)- less activity on the left, more on the right

Raine

What was concluded about the reduced activity in the prefrontal cortex?

Study These Flashcards

It can explain why murderers have lower self control and/ or lower intelligence- could reduce employment and increase risk of criminal activity

Raine

What was concluded about reduced activity in the amygdala?

Study These Flashcards

Lack of fear- increase aggressive/ criminal activities

Practical Applications- Plastic Surgery

What is it and who’s research supports?

Study These Flashcards

Reconstructive face surgery to make crimincals look more appealing
Lewinson- focused on defining features like nose, ears, facial scars that were associated with criminality

Practical Applications- Plastic Surgery

How can it reduce criminality?

Study These Flashcards

Makes them more willing to co-operate with authority, learn a trade
Improve self esteem- low self-esteem associated with crime
Improve reputation and first impressions of wider society

Practical Application- plastic surgery

How can it help reduce criminality in terms of differences in interation with others?

Study These Flashcards

Breaks the cycle of the self-fulfilling prophecy giving them a new start- people treat them as a non criminal

Plastic Surgery

What are possible strengths and weaknesses of it?

Study These Flashcards

Strength- Shown to work (Lewinson)
Weakness- Not suitable for all groups of offenders (young children), ineffective if no face deformities present

# Practical Application- Drug therapy What is it?

Chemical castration- provides oestrogen supplements to counteract testosterone levels

# Practical Application- Drug therapy How can it help reduce criminality? | Who's study supports?

* Jacobs- males with XYY chromosomes are more likely to be aggressive prisoners and show increased tesdtosterone levels- drug therapy reduces impact of genetic differences (too much testosterone) * Prisoners showed reduction in aggression, anxiety and sexual desire- drug therapy can reduce behaviour in violent crimes (rape, murder etc)

# Praxtical Application- Drug Therapy What is a strength and a weakness of drug therapy?

* Strength- easy to achieve (tablets) * Weakness- only suitable for males with biochemical disorders (XYY), only suitable for violent crimes

# Topic 2 What are the two competing motives in fingerprint analysis?

* Analysts are motivated to catch criminals by identifying suspects * But they're motivated to catch the right criminals (to avoid making mistakes)

# Hall and Player What is the aim of the investigation?

To investigate whether fingerprint experts were emotionally affected and whether the context of the crim would bias their judgement

# Hall and Player Who were the sample for the investigation?

70 fingerprint experts- Metropolitan Police Fingerprint Bureau * experience from less than 3 months to 30+ years * Volunteers * Burglary- terrorism * Recorded anonymously

# Hall and Player What design was used?

Lab experiment and independent measures

# Hall and Player What was the IV?

Emotional context (details in crime report) * Low emotion context- Forgery- "tried to pay with fake £50 note" * High emotion context- Murder- same but with "fired two shots at victim"

# Hall and Player What was the DV?

Explaining decisions on the prints in reports * Identification- match * Exclusion- No match * Insufficient- not able to compare * Inconclusive- compare but not individualise

# Hall and Player Where was a known fingerprint imposed on?

a £50 note- independent analysts confirmed the poor quality of the prints

# Hall and Player What did the crime scene report include? | What other things did participants get?

Details of crime- high and low emotion | Test mark card, set of 10 prints, magnifying glass

# Hall and Player Why is ecological validity strong in the procedure? ## Footnote Why can ecological validity equally be weak?

Participants were told to treat situation like a normal day but not to discuss prints ## Footnote No time limit- unrealistic to real life as usually, fingerprint analysts are working against the clock

# Hall and Player What percentage of those looking at high-emotion crime reports were affected?

50%

# Hall and Player What percentage of those in the low-emotion condition were affected?

# Hall and Player What was concluded about emotional context in crime reports and the affect on analysts?

Emotion does affect analysts but doesn't impact decisions

# Application- Topic 2 What is the filler control method and what does it involve?

* Suggests removing knowledge that comparison print definitely belongs the suspect- analysts unaware it belongs to a suspect= reduces bias towards finding print as the 'criminals' * This drives competing motivation to find the right criminal

# Application- topic 2 How can the filler control method for reducing collection of forensic evidence be implemented?

* Analysts should be given six suspects' prints (one from actual, 5 plausible filler prints) * Analyst has to identify which print set matches instead of declaring match/ no match

# Application- Topic 2 Give a strength and a weakness of the filler control menthod.

* Strength- reduces bias and increases validity of judgements made * Weakness- Time consuming (time wasting)

# Application- topic 2 What is working in isolation from other evidence?

* Analysts should be unaware of any crime scene info to avoid emotional context * They should come to their own conclusions and not be informed of initial judgement

# Application- Topic 2 How can working in isolation from other evidence reduce bias when collecting forensic evidence?

* Should be given evidence that needs to be analysed with no other contextual info * Decisions won't be impacted by emotional context * Final decision should be compared with original case findings to ensure a decision has been made, not just declaring a match or no match

# Application- Topic 2 Give a strength and a weakness of working in isolation of other evidence.

* Strength- increased validity (it works), reduces bias * Weakness- missing contextual cues, holistic approach
