The water-level task is an experiment in developmental psychology and cognitive psychology[1][2]
The experiment attempts to assess the subject's reasoning ability in spatial relations. To do so the subject is shown pictures depicting various shaped bottles with a water level marked, then shown pictures of the bottles tilted on different angles without the level marked, and the subject is asked to mark where the water level would be.
Sex Differences
The water-level task has been of interest to psychologists due to a significant sex difference in performance of the task. Multiple studies have indicated that female participants fail the task at a significantly higher rate than male participants.[3]
One typical study from 1989 found that 32% of college women failed the test, compared to 15% of college men.[8] A 1995 experiment found that 50% of undergraduate males and 25% of females performed "very well" on the task and 20% of males and 35% of females performed "poorly". Similar sex differences have been confirmed internationally.[8] The difference in performance between men and women has been estimated, in terms of Cohen's d, to be between 0.44–0.66 (i.e. between 0.44 and 0.66 standard deviations).[4]
