Its been a while and I need to get back on this…. here is part 2… lets see if we cant get a few more up in the coming months.. plus an insight into my new book….
VIOLENCE IT’S NATURAL LET IT BE.. Part 2
Yochelson and Samenow (2013)
A study of thinking patterns in criminals.
Aim: To understand the make up of the criminal personality.
Design: A longitudinal study using interviews that spanned over a 14 year period. The interviews were based on Freudian therapy techniques, which aimed to identify the root cause of the criminal behaviour.
Sample: 255 males from various backgrounds who had been found guilty by reasons of insanity and secured in a mental institution. Only 30 of the participants completed the interviews, and only 9 made any significant progress towards rehabilitation. Findings: Identified 52 thinking patterns that were common in the criminals.
External attribution they viewed themselves as the victim and blamed others for the situation. Lack of interest in responsible behaviour sees it as pointless. Closed thinking not receptive to criticism.
Conclusion: These ‘errors’ in thinking are not unique to criminals, but were suggested to be displayed more by criminals than law behaving citizens. They also put forward the theory of free will to explain criminal behaviour. This has five points to it:
- The roots of criminality lie in the way people think and make their decisions.
- Criminals think and act differently than other people, even from a very young age.
- Criminals are, by nature, irresponsible, impulsive, self-centered, and driven by fear and anger.
- Deterministic explanations of crime result from believing the criminal who is seeking sympathy.
- Crime occurs because the criminal wills it or chooses it, and it is this choice they make that rehabilitation must deal with.
Does the criminal mind of one parent transfer via inheritance to the mind of their offspring? This has been a question that scientists and researchers have attempted to answer for quite some time now and the above does not really point us in a direction that one can be confident in!
The Construct We Call The Mind.
“Rabbit’s clever,” said Pooh thoughtfully.
“Yes,” said Piglet, “Rabbit’s clever.”
“And he has Brain.”
“Yes,” said Piglet, “Rabbit has Brain.”
There was a long silence.
“I suppose,” said Pooh, “that that’s why he never understands anything.”

To date the brain and it’s functioning process are still the subject of large amounts of research and, according to a popular myth, we only use 10% of its capacity! Wikipedia (2014) ‘the 10% of brain myth is the widely perpetuated urban legend that most, or all, humans only make use of 3%, 10% or some other small percentage of their brains. It has been misattributed to people including Albert Einstein.
By association, it is suggested that a person may harness this unused potential and increase intelligence. Though factors of intelligence can increase with training, the popular notion that large parts of the brain remain unused, and could subsequently be “activated”, rest more in popular folklore than scientific theory. Though mysteries regarding brain function remain e.g. memory, consciousness etc, the physiology of brain mapping suggests that most, if not all, areas of the brain have a function’.
The mind of humans is very closely related in structure and in some ways function to that of the ‘Rat’. Research by Smith and Alloway (2013) at the Penn State Centre for Neural Engineering and affiliates of the Huck Institutes of the Life Sciences, detail their discovery of a parallel between the motor cortices of rats and humans that signifies a greater relevance of the rat model to studies of the human brain than scientists had previously known. “The motor cortex in primates is subdivided into multiple regions, each of which receives unique input that allow it to perform a specific motor function”
In the rat brain, the motor cortex is small and it appeared that all of it received the same type of input. We know now that sensory input to the rat motor cortex terminate in a small region of the motor cortex that is distinct from the larger region that issues the motor commands. Our work demonstrates that the rat motor cortex is parcellated into distinct sub regions that perform specific functions, and this result appears to be similar to what is seen in the primate brain.”
“You have to take into account the animal’s natural behaviours to best understand how its brain is structured for sensory and motor processing,”. For primates like us, that means a strong reliance on visual information from the eyes, but for rats it’s more about the somatosensory input from their whiskers.” In fact, nearly a third of the rat’s sensory motor cortex is devoted to processing whisker related information, even though the whiskers occupy only one third of one percent of the rats total body surface. In humans, nearly 40 percent of the entire cortex is devoted to processing visual information, although the eyes occupy a very tiny portion of our body’s surface. It certainly seems from this research that the cortical mapping that occurs in the brain of a human is very similar to that of a rat; the big difference is the inflated size of our cerebral cortex.
Primitive neuro anatomy of the brain include impulses of rage and fear, that are balanced by the operating functions of the orbital cortex, which is responsible for emotional controls, that we know as moralization and self-control. The brain is certainly complex. However, the boundaries of its operations are slowly beginning to fail, not least due to the unfortunate circumstances some individuals have had to endure when accidental damage occurs to regions of their brain.
Pinker (2012) recounts an unfortunate accident that happened to a man called Fineus Gage, a railway foreman responsible for dynamite placement, he tapped down some blasting powder in a hole in a rock, setting off a premature explosion that sent the blasting iron up through his cheekbone and out the top of his skull. A 20th century computer reconstruction of the damage to the brain based on the holes in the skull, suggest that the rod tore up his left orbital cortex, along with the ventral medial cortex on the inside wall of the cerebrum.
Gage’s sensory, memory and movement were still available to him, although something about him had changed, he was no longer the same person, the damage that had occurred had caused an effect that was not just the loss of a capability that was controlled by the brain, this was more a change in his animal like behaviour.
Pinker quotes his doctor at the time saying “he is now fitful, uses the grosses of profanities, does not care about his friends, is persistently obstinate, plans future actions which are quickly abandoned, a child in his intellectual capacity and manifestations, yet has the animal passions of a strong man. Previous to his injury he possessed a well-balanced mind and was looked upon by those who knew him as a shrewd smart businessman, very energetic and persistent in carrying out all his plans. In this regard his mind was radically changed, so much so that his friends would say, that he is no longer Gage”
This type of evidence points towards clues that the brain and the control of emotions are closely linked and interactive with each other, some parts responsible for holding other parts in check.
This leads to an understanding that the human brain has been wired for violence, it is not a random development and in our evolutionary past, it was required as part of human nature to ensure survival, by the use of predation, dominance and vengeance. We must also not forget that humans have a great capacity for self-control, seeking peace or loving thy neighbour. However it is these acts of violence that are really nothing other than a means to strip resources from another individual that we now term as criminality.
One particular region of the human brain that contains several different areas all linked together, and is believed to be responsible for violent acts, is a region called ‘the rage circuit’ The neuro scientist Yank Punck Cept describes what happens when he sent an electrical magnetic current through a part of the rage circuit of a cat! “Within the first few seconds of the electrical brain stimulation, the peaceful animal was emotionally transformed, it leapt viciously toward me with claws unsheathed, fangs barred, hissing and spitting. It could have pounced in many different directions, but its arousal was directed right at my head, fortunately a plexie glass wall separated me from the enraged beast.
Within a fraction of a minute after terminating the stimulation the cat was again relaxed and peaceful and could be petted without further retribution’. This rage circuit in the cat brain has a corresponding counterpart in the human brain cited by Pinker (2012) This region in our own brain, can also be stimulated in the same manner as the cat, eliciting emotionally enraged responses, the only difference is that the cat hisses whereas humans have a propensity to use in appropriate language and violence.
One of the distinct differences in violent behaviour is between violence that is being used for dominance and violence used for predation. Observe two cats who find themselves faced off against each other, their hair stands on end, they assume a hunched and erect posture and all manner of cat noises emanate from within, so much so that when some humans use noise as a means of posturing, we find the term ‘cat fight’. Yet when the same cat comes upon a mouse or bird the behaviour is markedly different, now the cat is silent, determined and single mindedly focused on taking the life of the poor creature in its path.
Humans display the same behavioural patterns, these are evidenced in the typical Saturday night encounter when two males face off against each other. They inflate their chest, clench their fists, use language that threatens and insults the other party, however in the majority of cases even when fights start they are usually all blown out very quickly, they may have a few bruises and maybe a bone or two broken but there is, in the majority of incidents, no lasting trauma and unless they are very unfortunate to sustain a fall, and strike their head in just the right place with just the right amount of force, then death will not occur. When a tool such as a blade is involved the percentages rise sharply in favour of death.
However, we also have the capacity for predation, which unveils itself in our ugly capacity to take the life of another human in such a manner as to cause disgust and outrage. We can stalk other individuals and subject them to all manner of depraved acts eventually taking their lives. Cannibalism is also evident in some tribes and was more commonplace in our history than many would like to admit.
Humans also have the capacity to switch from passive ‘I love the world and everyone in it’ to ‘temper enraged maniacs’ at the switch of a button. This behaviour is exactly like the electrically induced rage of the poor cat above. Then we have times when humans are out for revenge, during these times a cool calculating persona can be seen, stalking their prey and preparing for the sweet taste of payback, usually a blade or a gun in some parts of the world are used in a cold manner where death is a high probability. No words are used and the silent determination is like evil unleashed.
A good friend of mine was returning home one night when he came upon a group of young lads bulling another, he intervened, trying to calm the situation, the next thing he knew and remembers was one of them repeatedly striking him, he soon went down as a result of multiple stab wounds. One thing that sticks in his mind was the coldness of his attacker executing his assault in complete silence with the rage of a person possessed.
Scientists have been able to insert their electrodes into different rage circuits within the brain of a cat to elicit either hunting or attack mode behaviour Pinker (2012). It is therefore no great leap to see that humans have the same rage circuits within their brains and that different stimuli will bring forth the same behaviour patterns that the majority of our animal relatives also exhibit.
The rage circuit that is responsible for producing emotional responses that are linked to aggression, hunting and attacking can have very subtle effects that at first look the same. These circuits are organized in a hierarchy which emanate from the ‘hind brain’ where neuro mapping controls the muscles and behaviour actions of the animal. The hind brain is positioned on top of the spinal cord. However, the circuits that control these rage centres are situated higher up in the mid and fore brain. When the hindbrain of a cat is stimulated by electrical impulses the resulting rage is known by neuroscientists as ‘sham rage’ the cat hisses, bristles and extends its fangs, but all the time can be petted and stroked without fear that the individual will be attacked.
If the rage circuit higher up is stimulated, then the resulting emotional effect is much more significant, the cat becomes as mad as hell and instantly attacks the head of the nearest person.
Evolution has, over time, taken advantage of these different modes of reactions, animals use different body parts as offensive weapons, including, jaws, fangs, and antlers, with primate’s hands and feet. The hindbrain circuits that drive these peripheral actions can be reprogrammed or swapped out as a lineage evolves. The central programs that control an animals emotional state are remarkably conserved, including the lineage that leads to humans.
Neuro surgeons have discovered a counter part to the rage circuit of other animals in the brains of their patients. Pinker (2012) It would seem from these types of experiments and the discovery that human brains are not that different in their mental processes, that behavioural actions are not all under the complete control of the conscious mind and that mechanisms within our brains are pre wired for violence. Pinker goes on to describe the position and links to other systems of our brain.
The rage circuit is a pathway that connects three major structures in the lower parts of the brain. In the mid brain there is a collar of tissue called the ‘periaqueductal grey’, grey because it consists of grey matter, a tangle of neurons lacking the white sheaths that insulate output fibers, periaqueductal because it surrounds the aqueduct, a fluid filled canal that runs the length of the central nervous system from the spinal cord up to large cavities in the brain.
The periaqueductal grey contains circuits that control the sensory motor components of rage, they get input from parts of the brain that registers pain, balance, hunger, blood pressure, heart rate, temperature and hearing, particularly the shrieks of a fellow rat, all of which can make the animal irritated, frustrated or enraged. Their output feeds the motor programs that make the rat lunge, kick and bite, one of the oldest discoveries in the biology of violence is the link between pain or frustration and aggression.
When an animal is shocked or access to food is taken away it will attack the nearest fellow animal or bite an inanimate object if no living animal is available. The periaqueductal grey is partly under control of the hypothalamus, a cluster of nuclei that regulate the animals emotional, motivational and psychological states including hunger, thirst and lust. The hypothalamus monitors the temperature, pressure and chemistry of the blood stream and sits on top of the pituitary gland, which pumps hormones into the blood stream and amongst other things, regulates the release of adrenalin from the adrenal glands and the release of testosterone and estrogen from the gonads, which are part of the rage circuit.
In humans the Amygdala modulates the hypothalamus, as you will remember from earlier the Amygdala is responsible for memory, it also affects the emotional feeling that occur especially when fear is present and will encode these memories into our mind to remind us exactly what fear we should be tuned into. An angry face, aggressive posture, clenched fist, will all trigger neural activity in the Amygdala, this in turn sends a communication to our conscious mind with the message ‘remember the last time’
At the beginning of this chapter, I laid out two categories of violence, social violence and A social violence. It is now reasonably clear that structures and mechanisms within our brain produce two basic behavioural patterns, that of predation and domination and it is these two categories that link themselves to social or A social violence. Social violence being the path to domination and the attaining of resources, A social violence the path to predation, the killing of our own species, to also enhance the attainment of resources to survive and propagate, but not always.
The reasons we construct to explain why these behaviours are enacted are our minds attempt to civilize the moral code that many now live by, whereas in an age gone by, things were very different from what they are now, the rule of law and society supported aggressive, violent behaviour in a much more open and visceral way. Yes, we have also got the capacity for great acts of kindness and compassion, we are altruistic, cooperative, but let us not be deceived by this dichotomy, for humans have evolved complex structures to ensure survival, the showing of reciprocal lateritic behaviours is just another way of banking some credit for the possibility of future hardship.
