This is
really interesting researchEight-year-old children have a radically different learning strategy from twelve-year-olds and adults. Eight-year-olds learn primarily from positive feedback ('Well done!'), whereas negative feedback ('Got it wrong this time') scarcely causes any alarm bells to ring. Twelve-year-olds are better able to process negative feedback, and use it to learn from their mistakes. Adults do the same, but more efficiently.
The nice thing about this research is that it's done using fMRI analysis of what parts of the brain are activating, and when. IOW, for hard headed realists like myself, this is real research, not hippy dippy BS. If you want to change the behavior of younger children, you need to focus on positive reinforcement.
