Consultant forensic psychologist Dr Keith Ashcroft says that 'extreme caution must be exercised' when making any decisions on serial murderers being freed. Rehabilitating criminals has become a highly debated topic throughout the U.S. With the majority of criminals being repeat offenders, the correctional institution has made rehabilitation a top priority. This suggestion, that criminals such as serial killers can be rehabilitated to the extent that they are able to return to the outside world, has its opponents. Consultant forensic psychologist Dr Keith Ashcroft says that 'extreme caution must be exercised' when making any decisions on serial murderers being freed. The serial killer is a nihilistic repeat murderer, who often commits ghastly crimes out of pure hatred for society. As FBI experts describe him, he “exhibits complete indifference to the interests and welfare of society and displays an irresponsible and self-centered attitude. How can the answer be improved? Can Teen Killers Be Rehabilitated? But the racial disparities already apparent in the criminal-justice system are replicated among juvenile lifers. According to a 2005 report from Human Rights.
Violent psychopathic criminals may be unable to learn from punishment due to abnormalities in key parts of their brain, according to a new study.
Brain scans of violent offenders has shown that those with psychopathic tendencies react differently when confronted with punishment or a negative reaction to their behaviour.
This could be why psychopaths do not benefit from rehabilitation programs while other violent criminals often do.
Brain scans of psychopathic criminals showed significantly increased abnormal activation in the bilateral posterior cingulate cortex (above) when punished compared to other violent non-psychopathic offenders
Around one in five violent offenders are thought to be a psychopath and they are known to have higher rates of reoffending.

The researchers behind the latest study hope that their findings could help to develop new interventions in childhood that could reduce the risk of violence and reoffending.

RECIPE FOR A SERIAL KILLER
Serial killers are portrayed as cold, calculating and often obsessive but researchers have found that these traits may be linked to specific psychological disorders and childhood trauma.
By analysing reports, legal files and journals from cases of killers including Anders Breivik and Dr Harold Shipman, they found 28 per cent of high profile killers were thought to have suffred from Autism Spectrum Disorder (ASD).
In contrast, around one in 100 of the general population is thought to suffer from the condition.
There were additional reports that claimed a fifth had suffered a ‘definite or suspected’ head injury in the past.
Of those killers with ASD and/or a head injury, more than half had previously experienced psychosocial stress such as sexual or physical abuse, but also parental divorce.
The Glasgow research, therefore, concluded probably more than 10 per cent of serial killers on the whole, across the worldwide population, show signs of ASD, and a similar proportion have had a head injury.
This combination could potentially result in an individual being predisposed to develop into a mass murderer.
The scientists found that the psychopaths had reduced levels of grey matter and abnormal white matter in areas of the brain that are involved in learning from rewards and punishment.
Dr Nigel Blackwood, a psychologist at Kings College London, said: 'Psychopathic offenders are different from regular criminals in many ways.
'Regular criminals are hyper-responsive threat, quick-tempered and aggressive, while psychopaths have a very low response to threats, are cold, and their aggressively is premeditated.
'Evidence is now accumulating to show that both types of offenders present abnormal, but distinctive, brain development from a young age.
'We found that the violent offenders with psychopathy, as compared to both the violent offenders without psychopathy and the non-offenders, displayed abnormal responses to punishment within the posterior cingulate and insula when a previously rewarded response was punished.'
The researchers, whose work is published in the journal Lancet Psychiatry, conducted MRI scans on 12 male violent psychopathic criminal offenders and 20 male violent offenders without psychopathy from the UK.
The men had all been convicted of murder, rape, attempted murder and grevious bodily harm and were recruited from the probation service.
They were asked to complete a task that involved matching pairs of images of animals or furntiture displayed on a screen when they were in the scanner.
Each choice gained them or lost them points depending on their answer. The researchers then assessed what happened when they changed the rules of the game, removing points for answers that would have once won them points and vice versa.

Psychopaths like Hannibal Lecter, portrayed by Sir Anthony Hopkins (above), do not respond to rehabilitation
The same test was also conducted on 18 healthy non-offenders.
Dr Blackwood said: 'When these violent offenders completed neuropsychological tasks, they failed to learn from punishment cues, to change their behaviour in the face of changing contingencies, and made poorer quality decisions despite longer periods of deliberation.'
The scans also revealed the psychopaths had abnormal brain responses in the posterior cingulate and insula parts of the brain that are involved in reward and punishment learning.
The scientists believe their results could be used to help produce new treatments for violent offenders, particularly for those with psychopathy.
Dr Blackwood said: 'As our studies and those of others show, the abnormalities of brain structure and function associated with persistent violent behavior are subtle and complex.
Psychopathic offenders also showed abnormal activity in the right anterior insula of the brain (shown above)
'The results of our studies are providing insights into the neural mechanisms characterising adult violent offenders that may be used, along with other findings, in designing programs to reduce recidivism.
'Our results also provide hypotheses about the abnormal development of violent offenders to be tested in studies of children.'
Professor Sheilagh Hodgins, from the University of Montreal who was also involved in the study, said learning from punishment was an important part of regulating behaviour.
She said: 'Offenders with psychopathy may only consider the possible positive consequences and fail to take account of the likely negative consequences.
'Consequently, their behavior often leads to punishment rather than reward as they had expected.
'Punishment signals the necessity to change behaviour. Clearly, in certain situations, offenders have difficulty learning from punishment to change their behaviour.'

She added: 'Since most violent crimes are committed by men who display conduct problems from a young age, learning-based interventions that target the specific brain mechanisms underlying this behaviour pattern and thereby change the behaviour would significantly reduce violent crime.'
