LONDON (Dispatches) -- A six year study shows that children who have experienced poverty make more impulsive choices than children who don’t, leading totheir addictions later in life.
Researchers from Aston University School of Psychology , studied 146 children, with an average age of eight, living in some of the most deprived areas of England and compared them with children living in some of the most affluent neighbourhoods.
Children were given a choice between taking home a small amount of money (for example, £1) or getting £10 a week, or even more a year later. How long a person is willing to wait for the larger amount of money can be used to calculate a ‘discount rate’ that shows how much the waiting time reduces the value of the money.
An impulsive person might prefer £1 now because the value of £10 in six months is ‘discounted’ to less than £1 right now. This means that, for them, the £10, is discounted by £9 over the six-month wait.
A less impulsive person might be willing to wait six months for £10, but not wait for a whole year for £15. This means that, for them, the value of the £15 is discounted by £5 over the additional six-month wait. This discount rate is a measure of how impulsive someone is.
The results showed that children living in the most deprived areas had significantly higher discount rates than children living in the least deprived areas, regardless of age or intelligence, indicating that deprivation was the causal factor in the children’s choice.
