Give children a chance to explore and answer their own questions. Laura Schulz of MIT and one of her graduate students, Elizabeth Baraff Bonawitz, created a study to examine curiosity. They gave children jack-in-the-box toys and found that when children weren't told how the toy worked, they remained curious, they persevered and they continued to explore the toy to figure out how it worked, even when they had the opportunity to play with a new toy. Give children active games to play that promote focused attention and self control. A group of researchers headed by Megan McClelland of Oregon State use a game to assess these skills -- the Head-to-Toes Task. In one study in the fall of their preschool year, more than 300 children were asked to do the opposite of what the experimenter told them -- if told to touch their heads, the children were to touch their toes; if told to touch their toes, the children were to touch their heads. The children thus had to pay attention to the directions, remember the rules and inhibit the tendency to go on automatic and follow the directions of the experimenter. The researchers found this game predicted the children's literacy, vocabulary and math skills in the spring of their preschool year. They also found that those children who improved their focused attention and self control skills made the greatest gains -- equivalent to having an extra month of prekindergarten in terms of their gains in literacy and math skills, and an extra 2.8 months in vocabulary skills.
