Adult Perception of the Horizontal

Abstract: The conceptualization of the horizontal was tested by having 128 university students draw the water surface on pictures of tilted glasses, as if the glasses were half-filled with water. Most Ss made errors of more than 5°, which suggests that adults have difficulty, much as children do, with the concept of horizontality as tested by this task.

“…During scoring, the experimenters were blind as to the subjects' gender. Both the water-level and the horizontal tasks were scored using the customary water-level criterion (Rebelsky, 1964) requiring deviations of 5°or less for success in adults. Under visual conditions, some incorrect responses are expected from subjects considered to have mastered the water-level task (Wittig & Allen, 1984); therefore, successful subjects here were defined as those who produced at least three correct answers out of four.…”

“…To test this notion, they asked children to indicate the position of water and plumb lines under stimulus conditions that provided conflicting (nonparallel or nonorthogonal) alternative frames of reference, as when the water line needed to be drawn in a tilted bottle. The original description of the task and data seemed to imply that children would master this understanding by the age of 9 or 10, and thus investigators were surprised when reports began appearing showing that many adults had serious difficulty on the task and that women were disproportionately evidencing difficulty (Liben, 1978;Rebelsky, 1964;Thomas, Jamison, & Hummel, 1973).…”

“…Lines that did not deviate from the horizontal by more than 58 were accepted. Considering that such a criterion is customarily used with adults (Rebelsky, 1964) but that in younger participants motoric control might not be fully attained, the more lenient criterion of 108 (e.g. Liben and Golbeck, 1980) was also applied.…”
