A mother sits in a playroom with her young son. The phone rings. When she picks it up, a researcher watching through a two-way mirror asks her to look into her son's eyes and ''show him, in the way that feels most natural for you, that you love him''.
The mother is doing her best to connect, but this little boy won't return her gaze. He looks at her mouth, where the words are coming from, but it's as if he can't understand what she means.
Mark Dadds says some children literally cannot see the love in their mother's eyes. Professor Dadds, a parenting expert from the University of New South Wales, has just published results of his work in the British Journal of Psychiatry and the Journal of Child Psychiatry and Psychology that suggest the ability to make eye contact is vital in learning how to love other people.
For the past five years, he has been working with children referred to his Sydney clinic for sustained rages, continual aggression, calculated violence and, occasionally, cruelty to animals.
These are children with some of the worst behavioural problems, who score highly for ''callous, unemotional'' traits. In his studies in both Sydney and London, it was these children who did not meet their mother's gaze, even when told they were loved.
People marvel at the resilience of children who overcome appalling family backgrounds to make good lives. We understand when childhood trauma sends a child off the rails. But we also have to accept that even good parents can have mean children - how else to explain families where only one child seems to be callous and unemotional, while the siblings are not?
Dadds distinguishes between children who are emotionally ''hot'' - those who lash out at the world - and the much smaller subset of ''cold'' children - the ones who don't react emotionally, don't care about others' feelings and don't show remorse.
Disciplining them doesn't have much effect, he says, and even the most souped-up, hands-on therapeutic parenting programs can have trouble reaching them. Dadds calculates only one in 200 children would behave like this, but they're a troubling group whose behaviour, unchecked, turns into violence, criminality and isolation as they grow older. Studies suggest these are the children who could grow up to be psychopaths.
''Your garden-variety child that causes problems at home and school tends to be impulsive, highly emotional and disregulated, and they see hostility everywhere. They hit out, their aggression is a reaction to what they perceive,'' he says.
''But there's a much smaller group, whose aggression is proactive or predatory. And they don't respond as well to our standard parenting programs.''
Dadds's work with these ''cold'' children contributes to a body of research trying to map what Harvard experimental psychologist Steven Pinker calls ''the moral instinct'' - finding the neurological clues that switch on empathy. In his 2002 book The Blank Slate, an ironic title, for no child is that, Pinker says ''genetics and neuroscience are showing that a heart of darkness cannot always be blamed on parents or society''.
In The Science of Evil, Cambridge psychiatrist Professor Simon Baron-Cohen proposes that evil is the absence of empathy, and that ''zero-negative'' types - narcissists, borderline personalities, psychopaths- share a neurological disability that short-circuits their empathetic responses.
This in turn clicks with the twin studies produced by Dr Essi Viding, a colleague of Professor Dadds. When she was at Kings College, her 2005 analysis of 3,687 pairs of seven-year-old twins found that children with early psychopathic tendencies - the ''cold'' children - most likely inherited these traits, whereas the garden-variety aggression of the ''hot'' children was caused by environmental factors, such as family violence or neglect.
This is sensitive stuff, and the scientists are all keen to stress that the children they work with are not ''born evil''. Dadds is at pains to emphasise that ''psychopathy'' does not mean ''serial killer'' but callous disregard for the feelings of others - they could, as psychologist Robert Hare says in his book Snakes in Suits, find their place as easily in the corporate world as in the criminal.
Indeed, the emphasis of much of the studies has been in finding the best ways to teach these boys - they're overwhelmingly, though not always, boys - how to love and care for others before they harden their hearts forever.
More than 100 boys aged five to 16 in Sydney, and 24 children aged four to eight in London, took part in Dadds's studies. Both studies screened out mothers with histories of mental illness, drug or child abuse, or children with other significant behaviour issues such as hyperactivity or disabilities such as autism.
They were referred by parents or schools for what's called Oppositional Defiant Disorder, a sustained and exhausting defiance thought to affect between 3 and 5 per cent of children.
Within this group were the children who'd scored highly for ''callous, unemotional'' traits. Control groups of children with no history of bad behaviour were included in both studies. In Sydney, mothers and sons sat together for 30 minutes playing with toys and drawing family pictures. Then the mothers would be prompted to discuss a happy time and a sad time they'd recently shared with their son. Many of the fathers completed personality tests separately.
In London, mothers played with their children and then told them that they loved them. Most, but not all, of the children in London were boys. Some of the fathers completed personality tests to see if they had similar traits to their children.
In all cases, the mothers of the cold children were able to express their love as directly as mothers of the children with no behaviour problems. All the mothers, regardless of the challenges they faced in their day-to-day parenting, could provide their child with a direct dose of love when asked to do so.
But in both cities, the cold children did not return their mother's gaze, and did not seem to respond to their love - and it was apparent even in children as young as four.
Both studies concluded this reluctance to look into the mother's eyes was not the result of poor parenting or chaotic family lives but ''a trait characteristic of the male side of the family''.
Yes, the biological fathers of the cold children - but not stepfathers - were much more likely to display the fearlessness and low-level eye contact also seen in adult psychopaths. But Dadds says it is too soon, and the results too sketchy, to say for sure if this is because the fathers and sons share some genetically inherited neurological deficits.
''Gazing into the eyes is hard-wired into the human brain, and it's the first thing babies will detect in their environment,'' Dadds says. ''When they gaze at their mothers, it's the fundamental moment that sets the stage for the development of empathy and morality in humans. Some of the earliest evolved parts of our brains are dedicated to driving our attention to the eyes of other people.''
Studies of adult psychopaths have noted their lack of focus on the eyes of others, and it's associated with two other markers: an inability to recognise fear and a lack of empathy.
The absence of eye contact also helps to explain why the cold children don't respond well to the intensive parenting programs that have proved effective for other children with conduct disorders: perhaps they're missing the positive feedback the other children get when things are going well.
Dadds's studies investigate whether the lack of eye contact is a neurological deficit, more specific than the broad spectrum difficulties faced by autistic children, and yet more disturbing.
The failure to gaze may be the start of what could become ''cascading errors in the development of moral conscience and empathetic concern'', the studies conclude: the baby doesn't look in his mother's eyes, the mother never feels the baby's love, the toddler is remote, the mother is stressed, the child is aggressive, the parents are angry, the child shows no remorse, the family fights all the time, the teenager becomes aggressive and destructive. Finally, the adult is callous and calculating, as he's never understood or cared for the feelings of others.
The families Dadds sees for psychopathic behavioural issues ''tend to be pretty good parents: motivated, engaged and loving, not high rates of abuse,'' he says. ''The evidence so far is this is not something we can blame on the parents.'' Indeed, many families he sees have other children with different temperaments.
The new wave of genetic and neurological research into these ''remorseless'' children is finally shifting the burden of blame from the mothers, says Warren Cann, director of the Parenting Research Centre in Melbourne.
''It's like autism, that was once thought to be a parental deficiency, the cold mother. We went through it with schizophrenia, too. It's always been blamed on mothers and the way they treated kids. What our genetic studies are showing is that parenting is not a level playing field. When you've got a kid who is really oppositional, you fall back to negative strategies or feel helpless and defeated.''
But the new studies are also suggesting ways to reach these most difficult of children. If the love feedback loop begins with the eyes, Dadds thinks these children could be taught to return the gaze that will rewire the empathetic pathways through the brain.
Researchers in the US have reported that psychopathic prisoners can be taught to recognise the signs of fear in others.
Dadds has seen similar results with the cold boys. Usually, they have trouble recognising fear in other people, but when they're asked to focus on the eyes they learn to recognise the signs.
Teaching children to look and understand can be part of a specialised parenting program that could steer them towards a better life, Dadds says. He intends to study the effect of these parenting programs as his subjects grow up.
''Give them as much positive parenting as you can, enhancing the standard programs with extra dollops of love and engagement and eye contact to get these kids into the zone.''

We Need to Talk about Kevin screens in Australia from November 10.
Will the light ever shine on hearts of darkness?
Reading Lionel Shriver's bestseller We Need to talk About Kevin last year, Professor Mark Dadds found it both depressing and familiar. The eponymous Kevin and his anguished mother shared something of the stories he hears from families at his Sydney clinic.
''I recognised what the mother was going through. Was it all in Kevin? Was he born lacking the ability to notice and care about other people's feelings, or was it something about her being a reluctant mother from the beginning that had caused Kevin's problems?''
Kevin is the archetypal child with early psychopathic tendencies: he rejects affection, destroys property, torments other children, and has, his mother notes, ''an almost zen-like indifference to whatever you might deny him''.
The idea of ''the bad seed'' has fascinated us since Genesis, when Cain murdered Abel. In fairytales, changelings torment their mothers. In horror stories, demonic children destroy families from within.
It's also been a staple of cinema, from 1956 film The Bad Seed to 1993's The Good Son, a Macaulay Culkin vehicle with a script by English novelist Ian McEwan. Then there's the film of We Need to Talk About Kevin, starring Tilda Swinton as the mother, Eva, which opens here in November.
Shriver has always rejected the idea that Kevin was born bad: ''I would conceive of 'evil' more as an absence of something rather than a presence,'' she told Salon in 1993.
''People are born with greater and lesser capacities for all kinds of things - great art, intellectual achievement, and also things like empathy, interest, compassion. So, yes, I think it is possible that some people are born not very interested in things and don't really take on board the reality of other people or their feelings.''
Covering the trial of 10-year-old boys Robert Thompson and Jon Venables for the murder of Merseyside toddler Jamie Bulger in 1993, essayist Andrew O'Hagan addressed children's capacity for calculated cruelty: ''Most of our games, when I think of it, were predicated on someone else's humiliation or eventual pain.''
Last year, still haunted by the boys, he wrote in London Review of Books: ''It's said you can't unmake your childhood. But you can. You can unmake it every day of your adult life.''
This is the great theme of the John Steinbeck novel East of Eden. The central villain, Cathy Ames, is certainly psychopathic. ''As a child may be born without an arm, so one may be born without kindness or the potential of conscience,'' Steinbeck writes.
But in a novel that loops back to Cain and Abel, he insists that nobody is doomed to be bad. In a key biblical passage that provides the novel's final word, ''thou mayest triumph over sin''.
