This study examines the ability of a new visual vigilance task, the Preschool Vigilance Task (PVT), to differentiate between hyperactive and control preschoolers. The PVT was designed to be an objective measure of attention specifically for use with the preschool-age population. Hyperactive and control preschoolers were tested on the PVT and the Continuous Performance Task (CPT). Results indicated that both were useful in differentiating between hyperactive and control preschoolers. Implications for the utility of the PVT and future research directions are discussed.
本研究考察了一种新的视觉警觉任务——学前警觉任务（PVT）区分多动型和对照学前儿童的能力。PVT被设计为一种专门用于学前儿童群体的注意力客观测量方法。对多动型和对照学前儿童进行了PVT和连续操作任务（CPT）测试。结果表明，这两种测试在区分多动型和对照学前儿童方面都很有用。文中讨论了PVT的效用及未来研究方向。
