(Press-News.org) New research suggests children don't understand competitive behaviour until around the age of four.
A team of researchers from the University of Warwick and University of Salzburg found most children under 4 did not have a developed understanding of other people's perspectives — specifically, of the fact that what someone intentionally does depends on their take on the situation.
Johannes Roessler, from the Department of Philosophy at the University of Warwick, and his co-authors Beate Priewasser and Josef Perner from the Department of Psychology at the University of Salzburg, tested 71 children aged between 3 and 5 years old.
They first tested the children to assess whether they understood that people sometimes act on the basis of false beliefs.
Roessler said: "In the classical 'false belief task', children watch a boy put some chocolate in a drawer and go off to play. Someone comes along and moves the chocolate to the cupboard. The experimenter then asks children where the boy will go to retrieve his chocolate. Children under the age of 4 tend to predict that he will go straight to the cupboard, because that is where the chocolate now is — even though the boy had no means of knowing this!
"Older children tend to predict that he will go to the drawer, which is the correct answer because the boy believes the chocolate to be in the drawer. Thus younger children seem to lack a developed understanding that people's intentional actions reflect their perspective (beliefs) on how best to accomplish their goals."
The researchers wanted to explore how much young children's understand other people's goals: do they understand that an actor's goals reflect his or her perspective on what's desirable?
The team set up a game for the children. They each had a vertical stand and were told they had to throw a die and then put the corresponding number of beads on their stand. The aim of the game was to be the first to fill their stand with beads, taking them either from the central basket or from other players' stands.
Roessler said they wanted to see if the children would take beads from the basket (neutral move) or from another player (a competitive or 'poaching' move). The point of taking beads form another player's stand is of course not just to further one's own goal (to fill one's stand) but also to foil the other player's attempt to reach his or her goal (to fill his or her own stand). The intentional use of poaching moves then, may be expected to show an understanding that the two players have different, and conflicting, goals, i.e. different perspectives on which outcome is desirable.
The results showed that very few children who failed the false belief task showed any tendency to engage in competitive poaching moves. This was so even when these children suffered from their opponent's poaching moves: they would not 'retaliate'. This last finding was especially significant. If children understood the goal informing the other's poaching moves, one would expect them, at least occasionally, to respond in kind.
"The 'four years of age' rule isn't hard and fast. What's important is not the absolute age of the child, but the fact that those who do not understand how intentional action can be informed by false beliefs also tend to struggle with the idea of competition."

Researchers report a critical role for the complement system in early macular degeneration
2013-08-15
BOSTON (August 15, 2013) -- In a study published on line this week in the journal Human Molecular Genetics, Drs. Donita Garland, Rosario Fernandez-Godino, and Eric Pierce of the Ocular Genomics Institute at the Massachusetts Eye and Ear, Harvard Medical School, along with their colleagues, reported the unexpected finding that in mice genetically engineered to have an inherited form of macular degeneration, turning off the animals' complement system, a part of the immune system, prevented the disease.
Macular degenerations, which occur in several forms, are important ...
Beating blindness with vegetable oil
2013-08-15
Scientists working at the Research Center on Aging at the Health and Social Services Centre — University Institute of Geriatrics of Sherbrooke (CSSS-IUGS) have been studying strategies for protecting retinal pigment epithelium (RPE) cells. Dysfunction of the RPE is found in retinopathy and age-related macular degeneration, which is the leading cause of blindness of elderly people in developed countries.
Findings published today in the Canadian Journal of Physiology and Pharmacology suggest that incubating retinal cells with vegetable oils induces biochemical and biophysical ...
Rice technique expands options for molecular imaging
2013-08-15
HOUSTON -- (Aug. 15, 2013) -- A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards.
By measuring the vibrations between atoms using femtosecond-long laser pulses, the Rice lab of chemist Junrong Zheng is able to discern the positions of atoms within molecules without the restrictions imposed by X-ray diffraction (XRD) and nuclear magnetic resonance (NMR) imaging.
The technique can capture the structure of molecules at room temperature or very low or high temperatures ...

Growth of disorder of electrons measured in dual temperature system
2013-08-15
Researchers at Aalto University, Finland and the University of Tokyo have succeeded for the first time in experimentally measuring a probability distribution for entropy production of electrons. Entropy production means an increase in disorder when electrons are moved individually between two microscopic conductors of differing temperatures.
The researchers also showed that a connection prevails between two definitions of entropy that have been used. The result is significant for the design of future nanoelectronic devices. The study was published recently in the scientific ...

MicroRNAs have diagnostic and prognostic potential in urinary bladder cancer
2013-08-15
Philadelphia, PA, August 15, 2013 – German researchers have identified four biomarkers that correctly determine malignancy of urinary bladder cancers and contribute to the accurate prediction of patient outcomes. Their results are published in the September issue of The Journal of Molecular Diagnostics.
Current prognosticators of bladder cancer, such as tumor grade, stage, size, and number of foci, have limited usefulness for clinicians since they do not accurately reflect clinical outcomes. Therefore, investigators have been searching for new biomarkers with better diagnostic ...
UTHealth researchers link PRKG1 genetic mutation to thoracic aortic disease
2013-08-15
HOUSTON – (Aug. 15, 2013) – A multi-institutional team led by Dianna Milewicz, M.D., Ph.D., of The University of Texas Health Science Center at Houston (UTHealth) has found a recurrent genetic mutation that has been linked to deadly thoracic aortic dissections in family members as young as 17 years of age.
The gene known as PRKG1 makes a protein called cGMP-dependent kinase, type I. The PRKG1 mutation alters the function of the protein and causes the muscle cells in the wall of the aorta to respond incorrectly to pulsatile blood flow from the heart, and the change in ...
Remembering to remember supported by 2 distinct brain processes
2013-08-15
You plan on shopping for groceries later and you tell yourself that you have to remember to take the grocery bags with you when you leave the house. Lo and behold, you reach the check-out counter and you realize you've forgotten the bags.
Remembering to remember — whether it's grocery bags, appointments, or taking medications — is essential to our everyday lives. New research sheds light on two distinct brain processes that underlie this type of memory, known as prospective memory.
The research is published in Psychological Science, a journal of the Association for ...
