    Results obtained previously by others with a dot alignment task have been taken to imply that a line is perceptually attracted to the nearest vertical or horizontal axis of space. Angle matching experiments have been taken to imply the opposite. This discrepancy could be attributable either to different tasks or to different displays, or both. In five experiments, we replicated both previous findings and additional evidence indicated that the discrepancy is not display contingent, suggesting that at least one of the two methods does not measure perceived orientation.
