It has been shown (and probably experienced by all of us) that performing worse than our peers on a particular task results in negative self-esteem and poorer subsequent performance on the same task. How people respond when their peers perform better than they do has been studied in a variety of age groups and it turns out that preschoolers have thicker skin than adults do! Previous research has shown that preschoolers (4-5 year old children) maintain positive self-evaluations and high levels of performance even when they see that their peers have out-performed them. This is thought to occur because young children believe that achievement differences between themselves and their peers are adaptable; in other words, they think that if they try harder, they will be able to do as well as their peers in the future. http://www.physorg.com/news144592447.html Medicine & Health Thu, 30 Oct 2008 13:34:07 EST news144592447 It is better for children conceived by donor insemination to be told of their origins at an early age, according to the first large-scale study of people who are aware of their donor conception.
