abstract="The effect of contrast polarity on arrival-time judgment tasks was investigated in a simulated air traffic controller task. Each participant predicted which of two symbols moving to a contact point symbol would arrive when the display was terminated once the winning symbol was two-thirds of the distance to the given contact point. Accuracy was calculated as percentage correct and was submitted to a 5-way and a 6-way mixed-design ANOVA in order to examine the effects of contrast polarity. The results are discussed in conjunction with possible effects of contrast polarity on arrival-time judgments and the predominance of either distance or velocity information on these judgments.<p /><p>Language: en</p>",
