凡事简单就好

Keep it simple: children learn best from books with simple illustrations and no manipulative features such as "pop-ups", US researchers say. Their research, involving studies of children aged 20 months and between 30 and 36 months, found that at all ages children learnt best from the simple books. The children's manipulation of the flaps and pull-tabs might have increased their cognitive load such that they could not additionally process what the adult was saying about the book's content, the researchers wrote in the journal Applied Developmental Psychology.
