Researchers at Vanderbilt University discovered that when mothers just listened, providing no assistance or critique, while their children explained the solutions to pattern recognition problems, it markedly improved the children’s later problem-solving ability—more so than if the children had explained the solution to themselves or repeated the solution over and over in their heads. Previous research has shown that adults provided with an attentive listener gave more detailed solutions with more alternative ideas and better justifications than solutions generated in isolation.
