Memory and problem-solving
A number of psychological studies indicate that linguistic labels do make a difference for thinking, especially for memorizing and problem-solving.
In one experiment, two groups of persons were shown several meaningless shapes (see examples below). In one group, the shapes were given random names, in the other group, the shapes were not given names at all. It turned out that the group for whom the shapes had been given names were more prone to remember the names afterwards.
