Why are children so sensitive to inequality?

• Effects of relative poverty on material resources?

• Impact on family life and relationships?

• Direct experience of increased status differentiation?

Status differentiation has a direct effect on cognitive performance

Inequalities become entrenched early in life

• Cognitive scores at 3 years of age (MCS)

• Children with the most educated parents 12 months ahead of those with the least educated parents

• Children in families with incomes below our poverty line had scores

about 8 months behind those with incomes above it

• White children about half a month ahead of the all-UK average, followed by children from a mixed ethnic background, about half a month behind

• Bangladeshi and Pakistani children lowest vocabulary scores, with averages around 35, characteristic of the lowest tenth in the population at large

Prenatal exposures have long-term effects

• PRENATAL STRESS– Alcohol– Nutrition– Cigarette smoke– Breastfeeding– BIRTH WEIGHT/GESTATION

Cardiovascular disease Diabetes Mental health/behaviour IQ and education Reproductive health Social status (marriage) Birth weight of next generation Health-related behaviours Birth weight of next generation

Postnatal exposures have long-term effects

• Poor attachment• Maternal depression• Breastfeeding• Poor parenting

A mother who goaded her two toddlers to fight each other on video camera has received a 12-month suspended sentence, along with her mother and two sisters.

Zara Olver, 21, her 48-year-old mother Carole, and sisters Serenza Olver, 29, and Danielle Olver, 19, all admitted child cruelty at Plymouth Crown Court.

In the footage, a boy in a nappy was called a "wimp" for not hitting his sister back after she struck him.

The women laughed as the children hit each other with brushes and magazines.

But the footage was found by chance by the toddlers' father, on leave from the army, and he told social services.

The boy, aged two, is seen crying after being punched in the face by his three-year-old sister and is told by one of the four women in the room "not to be a wimp or a faggot" and to hit the girl back.

The court heard that, when interviewed by police, Carole Olver said: "I didn't see any harm in toughening them up - I done the same with my own children."

A two stage process: parental experiences of inequality shape child development

Parenting styles prepare children for the kind of social relations they may have to deal with in adulthood

Preparation for a society dependent on:- • trust, cooperation, reciprocity, empathy?

or:• fending for yourself, not trusting others?
