Materialistic society is 'damaging' children: poll

(Breitbart) Children feel under pressure to own the latest designer clothes and computer games and most adults believe the "commercialisation of childhood" is damaging young people's well-being, a poll said Tuesday.

A survey by GfK NOP for the Children's Society showed that out of the 1,225 adults questioned, 89 percent felt that children are more materialistic now than in previous generations.

Evidence submitted to the inquiry from children themselves suggests that they do feel under pressure to keep up with the latest trends, the society added.

The poll is part of a larger inquiry into childhood and includes evidence by professionals and members of the public on issues such as lifestyle, learning, friends and family.

Professor of child psychology Philip Graham -- who is leading the inquirys lifestyle theme -- believes that commercial pressures may have "worrying psychological effects" on children.

"One factor that may be leading to rising mental health problems is the increasing degree to which children and young people are preoccupied with possessions; the latest in fashionable clothes and electronic equipment.

"Evidence both from the United States and from the UK suggests that those most influenced by commercial pressures also show higher rates of mental health problems," he said.

Commenting on the results of the poll, chief executive of the Childrens Society Bob Reitemeier said: "As adults we have to take responsibility for the current level of marketing to children. To accuse children of being materialistic in such a culture is a cop out.

"Unless we question our own behaviour as a society we risk creating a generation who are left unfulfilled through chasing unattainable lifestyles."

Rowan Williams, the Archbishop of Canterbury and patron of the inquiry, added: "Children should be encouraged to value themselves for who they are as people rather than what they own.

"The selling of lifestyles to children creates a culture of material competitiveness and promotes acquisitive individualism at the expense of the principles of community and cooperation."

Other results in the poll showed that just over 60 percent wants the government to ban junk food adverts and nearly 7 in ten agreed that violent video games make children more aggressive.

The final report and recommendations of the Good Childhood Inquiry will be published in early 2009

Acne May Prevent People From Participating In Sport And Exercise, Says Research

ScienceDaily (Feb. 26, 2008) — Acne patients who are highly anxious about their skin condition say they are less likely to participate in sport or exercise, according to new research at the

The study, published in the Journal of Health Psychology, involved 50 young to middle-aged adults recruited from a national acne support group.

As well as saying that they were less likely to participate in sport or exercise, acne sufferers who perceived their skin to be negatively evaluated by others also experienced lower self-esteem and a poorer quality of life. This pattern was similar in both men and women.

The researchers say that ‘dermatological social anxiety’ is often overlooked in studies on motivation for sport and exercise in favour of physical inhibitions.

“The skin is the most visible organ in the human body and, as such, is an important part of personal image,” said Dr Martyn Standage, a lecturer in the School for Health at the University of Bath.

“Fear of having one’s skin evaluated by others has implications for physical and social wellbeing.

“Sport and exercise activities provide many opportunities for the skin to be exposed to evaluation. Due to this, acne sufferers may become so anxious about their appearance that it prevents them from participating in physical activity.”

Children Show Goal-oriented Behavior By Age Three

ScienceDaily (Feb. 22, 2008) — Hang on, parents. After the terrible twos come the goal-oriented threes. Kids seem to grow into the ability to act in pursuit of goals outside of what they can immediately sense sometime around that age, according to a new study. Researchers found that by around age 3, children appear to shape their behavior in response to the outcomes they've come to expect. Anticipated outcomes that they value move them to act more than do outcomes that they don't -- a hallmark of emerging autonomy.

At the University of Cambridge, a trio of psychologists trained 72 children between 18 months and 4 years old, divided into three 10-month age bands (averaging 1.3 to 2.2 years, 2.3 to 3.075 years, and 3.08 to 4 years) to touch a red or green butterfly icon on a touch-screen display to see different cartoon video clips. The children came to associate one butterfly with one cartoon sequence and the other butterfly with another.

After that, the experimenters devalued one of the outcomes by showing that sequence repeatedly, until the children became bored with it. Thus, the less-viewed cartoon clips became, by contrast, more interesting and valuable. The researchers then re-tested the children, who should now have associated one butterfly with a valued cartoon and the other butterfly with a less-valued cartoon.

Relative to the younger children, those who were 32 months (nearly 3 years) and older touched the butterfly for the less-valued cartoon significantly less often than they touched the butterfly for the more novel cartoon. During that test, the cartoons were not actually presented; the children had to rely on their memories of which butterfly icon produced which cartoon. This test thus showed that the actions of the older children behavior depended on the current values of the
