Perception of verticality by boys and girls in grade 6.
Understanding of the principle of verticality was tested by having 246 sixth grade students draw a pendulum on pictures of an abstract shape similar to a steeple. Girls performed more poorly than boys. Verticality was apparently much better understood by subjects than horizontally, also tested to provide a comparison.
