Interesting research on children

Here's some interesting research done recently on 5 to 7 year old children to see whether they were aware of how their emotional and physical states and surroundings would affect their schoolwork. This paragraph summarizes their findings:

They found that children of all ages understood that negative emotional and physical states would lead to poorer school performance. The fact that young children knew that negative emotions could cause poor school performance was especially surprising, since parents and teachers often focus on the physical side of getting ready for school (hence the advice to get lots of rest or eat a good breakfast), and rarely talk about the emotional side (for example, advising children to try not to feel sad). The researchers also found that children understood that levels of interest, effort, and classroom noise would affect performance.

I'll have to put more effort into lessening the negative emotional states that occasionally attend my morning "school" sessions with dd5.
