The purpose of this study was to gain further insight into the normal development of praxis in children and to identify some of the learning strategies used by children during a motor-sequencing task. I analyzed the errors made by kindergarten and third-grade children during a motor-sequencing task and their reported memory strategies. I studied the following three groups of children: kindergar...

Young children are remarkably prosocial, yet the mechanisms driving their prosociality are poorly understood. In two studies, we looked at whether a need for reciprocity drives children’s prosocial behavior. In Experiment 1, children were given a puzzle task to complete in which they were either missing 2 pieces (experimental group) or not (control group). All children then received 2 puzzle pi...

One of the major questions in the cognitive science of language is how children learn the productive systems that encompass the grammar of our native languages. This paper addresses how children learn morphology, the systematic relationship between form and meaning. For example, the English plural can be made in one of many ways, most commonly with the addition of the suffix /-s/. While such pa...

A radial haemolysis test was used to investigate immunity to mumps. Antibody was found in 92 (42%) out of 220 children aged up to 5 years, 124 (78%) out of 159 children aged 6--10 years, 192 (86%) out of 222 children aged 11 years, 138 (92%) out of 150 children aged 15 years, and 280 (95%) out of 296 women attending an antenatal clinic. A group of 307 cadets aged 16--18 years were also tested a...

BACKGROUND The aim of this study was to analyse the prevalence and severity of dental caries among Korean children aged 8 and 12 years over a period of 12 years by determining the number of decayed, missing, and filled teeth (DMFT) and the Significant Caries index (SiC index). METHODS Stratified cluster-sampled data from the National Oral Health Survey conducted from 2000 to 2012 were analyse...

the economic exploitation of children is an insult to humanity. all over the world children continue to work, putting at stake their education, their health, their normal development to adulthood, and even their lives. millions of them work under hazardous conditions which present dangers to their health, safety and welfare. they toil in mines and quarries, are exposed to agrochemicals in agric...

background : the goal of the present study was to develop and validate the persian version of the acceptable noise level (anl) test in normal, persian-speaking children aged 5-8 years. methods : this tool-making and non-experimental research was conducted in two stages. in the first stage the proper story was selected and recorded after evaluation of its content validity. in the second stage th...

A large literature shows that retrieval practice is a powerful tool for enhancing learning and memory in undergraduates (Roediger & Karpicke, 2006a). Much less work has examined the memorial consequences of testing school-aged children. Our focus is on multiple-choice tests, which are potentially problematic since they minimise retrieval practice and also expose students to errors (the multiple...

Schistosomiasis is a chronic disease that affects ∼200 million people. The extended health impact of the disease has been estimated to exceed that of malaria or tuberculosis and to be nearer to that of HIV/AIDS. Within endemic areas, children carry the heaviest burden of infection. Infection/disease is controlled by the treatment of infected subjects with the anthelminthic drug praziquantel. Gl...
