In a study published in an upcoming issue of The Journal of Child Psychology and Psychiatry researchers show that over reactive parenting, such as heavy criticism or yelling as a response to a child's negative behavior, can produce higher levels of aggression or rule-breaking in a child who is normally introverted, non-benevolent, non-conscientious, or imaginative. Children who are extraverted, benevolent, conscientious, or not that imaginative by nature are least adversely affected by this parental response. http://www.physorg.com/news177863747.html Medicine & Health Thu, 19 Nov 2009 14:50:02 EST news177863747 Children as young as 12 have a strong sense of their personal futures and can reflect thoughtfully on what life might hold for them, according to new research funded by the Economic and Social Research Council and led by Professor Paul Croll of Reading University and Professor Gaynor Attwood of the University of the West of England. http://www.physorg.com/news177493714.html Other Sciences Sun, 15 Nov 2009 08:00:01 EST news177493714 According to research from the University of Gothenburg, Sweden, a preschooler's gender determines how he or she is treated and responded to in play and learning activities, and when the children's possibilities become expanded, it is usually a result of the children's and not the teachers' initiative. http://www.physorg.com/news176465003.html Other Sciences Tue, 03 Nov 2009 10:50:09 EST news176465003 Young people mainly select their friends according to the image they have of another person, irrespective of whether the person concerned actually satisfies that image. Dutch researcher Maarten Selfhout has demonstrated that young people consider themselves to be the most important factor in a friendship. Nevertheless friendship can still exert a significant influence: boys become criminal and girls become depressed. http://www.physorg.com/news175507272.html Other Sciences Fri, 23 Oct 2009 09:20:01 EST news175507272 Teenage boys in Sweden take less responsibility than girls for preventing the spread of chlamydia and other sexually transmitted infections, according to a new study from the Sahlgrenska Academy at the University of Gothenburg, Sweden. http://www.physorg.com/news174661763.html Medicine & Health Tue, 13 Oct 2009 16:10:06 EST news174661763 Persistent infection with high-risk types of human papillomavirus (HPV), a sexually transmitted virus, is known to be a cause of cervical cancer. Current guidelines prioritize HPV vaccination of pre-adolescent girls, which has been shown to be cost-effective in previous studies, but the value of vaccinating boys in the United States has been unclear. In a new study, Harvard School of Public Health (HSPH) researchers found that if vaccine coverage and efficacy are high in girls, a universal recommendation to vaccinate young boys is unlikely to provide comparatively good value for resources, compared with vaccinating girls only. http://www.physorg.com/news174286325.html Medicine & Health Fri, 09 Oct 2009 06:30:01 EST news174286325 (PhysOrg.com) -- New research from The University of St. Andrews in Scotland has discovered that teenage girls are attracted by deep male voices, while younger girls feel intimidated by them. http://www.physorg.com/news172304097.html Medicine & Health Wed, 16 Sep 2009 10:20:01 EST news172304097 (PhysOrg.com) -- As a new mother herself, Brenda Lohman admits to being shocked by the results of a new study she co-authored. It found that among nearly 1,000 low-income families in three major cities, one in four children between the ages of 11 and 16 reported having sex, with their first sexual intercourse experience occurring at the average age of 12.77. http://www.physorg.com/news169399090.html Other Sciences Thu, 13 Aug 2009 16:30:02 EST news169399090 (PhysOrg.com) -- A team of researchers with the National Institute of Mental Health (NIMH), including a Georgia State University scientist, have found differences between girls and boys in how parts of the brain develop in responding to peer judgments - with girls becoming more preoccupied with how peers view them, while boys become more focused on their place in groups. http://www.physorg.com/news167580730.html Medicine & Health Thu, 23 Jul 2009 15:50:06 EST news167580730 Parents who value strenuous team sports are more likely to influence their children to join a team or at least participate in some kind of exercise, and spend less time in front of the TV or computer, a new study says. http://www.physorg.com/news166081560.html Medicine & Health Mon, 06 Jul 2009 06:46:46 EST news166081560 Both boys and girls have issues, but boys seem to be the ones getting the raw deal. According to Judith Kleinfeld, professor of psychology at the University of Alaska Fairbanks in the US, issues affecting boys are more serious than those affecting girls, but they have been neglected by policy makers. Her review (1) of issues characterizing American boyhood, how they compare to those affecting girls, and the lack of initiatives in place to address them has just been published in the June issue of Springer's journal Gender Issues. http://www.physorg.com/news163680614.html Medicine & Health Mon, 08 Jun 2009 11:50:40 EST news163680614 Young children think about gender in the same way they think about species of animals. They believe, for example, that a boy's preference for football is innate, as is a girl's preference for dolls, just as cats' behavior is innately different from dogs'. http://www.physorg.com/news160213396.html Medicine & Health Wed, 29 Apr 2009 08:43:58 EST news160213396 A new longitudinal study of children's personality traits and interests tells us that sex-typed characteristics develop differently in girls and boys.

In their own words, the young men often describe facing challenges such as growing up with troubled family lives, having little or no support when they began to fail at school, and witnessing violence in their own homes and communities. The study advocates broadening the view of abusive behaviors within dating relationships to explore the myriad environments - school, home and community - that affect boys' lives and actions. http://www.physorg.com/news143222210.html Medicine & Health Tue, 14 Oct 2008 16:56:50 EST news143222210 Obese teenagers are much more likely to suffer from metabolic syndrome - which can lead to heart disease - if they live in Brazil than Italy, according to a study in the October issue of IJCP, the International Journal of Clinical Practice. http://www.physorg.com/news143205321.html Medicine & Health Tue, 14 Oct 2008 12:15:21 EST news143205321 Society holds that when it comes to aggression, boys hit and punch, while girls spread rumors, gossip, and intentionally exclude others, a type of aggression that's called indirect, relational, or social. Now a new analysis of almost 150 studies of aggression in children and adolescents has found that while it's true that boys are more likely to engage in physical aggression, girls and boys alike take part in social aggression. http://www.physorg.com/news140762398.html Medicine & Health Tue, 16 Sep 2008 05:39:58 EST news140762398 The first study to include a significant number of aggressive girls with conduct problems indicates that psychological conditions including conduct disorder may have separate causes in the two sexes. http://www.physorg.com/news140361288.html Medicine & Health Thu, 11 Sep 2008 14:14:48 EST news140361288 We've all heard it. Many of us in fact believe it. Girls just aren't as good at math as boys. But is it true? After sifting through mountains of data - including SAT results and math scores from 7 million students who were tested in accordance with the No Child Left Behind Act - a team of scientists says the answer is no. Whether they looked at average performance, the scores of the most gifted children or students' ability to solve complex math problems, girls measured up to boys. http://www.physorg.com/news136126991.html Other Sciences Thu, 24 Jul 2008 14:03:11 EST news136126991 UK and US guidelines on how much physical activity children need to boost their health and stave off obesity need to be revised, conclude researchers in a study published ahead of print in the Archives of Disease in Childhood. http://www.physorg.com/news134043132.html Medicine & Health Mon, 30 Jun 2008 11:12:12 EST news134043132
