In this episode about the word, "antediluvian," host Lynn Hickernell includes excerpts from the books The Velveteen Rabbit and The 14th Goldfish (courtesy of the folks from Book Power for Kids!), "Say What?" about the expression, "You can't teach an old dog new tricks," "It Came From the Internet," "GET IT?!?!?" and the Miss Lynn song, "Studebaker Truck."
I found out about the study regarding the ages at which different cognitive skill develop in this radio interview with author Rich Karlgaard.
