title: The effect of scale-side, indicator type, and control plane on direction-of-turn stereotypes for Hong Kong Chinese subjects.
abstract: This study investigates the influence of scale-side, pointer type, direction-of-increase, and control plane on direction-of-turn stereotypes for Chinese subjects using a variety of configurations of a linear display with a rotary control. Pointer type and direction of increase did not have a significant effect on direction-of-turn expectation. Strong stereotypes are found when Warrick's principle and the scale-side principle do not clash. In such a configuration, the scale is on the opposite side of the display to the control, and the display indicator moves in the same plane as the control. However, when the two principles clash, stereotypes are weakened or eliminated and no single principle dominates. For a rotary control placed to the right of a horizontal linear scale in the frontal plane there are strong clockwise-for-right and counterclockwise-for-left stereotypes which dominate the scale-side principle when there is a clash. The most marked stereotypes and fastest response times are obtained for the horizontal display with the control in the same frontal plane.
