Researchers actually found something that was already known for some time. 20 years ago I remember reading an old book about learning techniques. One of the techniques in it, and one that I use for myself and my kids is to sound out the answer to questions in various tones. For instance: 8 times 6 equals FORTY EIGHT (yelled). 8 times 6 equals forty eight (whispered). 8 times 6 equals forty eight (monotone). etc... It does work, but it frustrates me that these researchers think this is something new.
