认证是一个重要的认知过程，用于确定一个人对一个物体的最初识别是否被额外的感官信息所证实。虽然身份验证对于与许多对象（包括食物、网站和有价值的文件）的安全交互至关重要，但用于获取额外感官数据以支持身份验证的视觉定向策略仍然知之甚少。当无法预测伪造的可靠视觉线索时，在物体表面广泛分布固定可能是有用的。但是，策略性地固定特定的对象定义属性会更有效，并且会带来更好的身份验证性能。为了进行调查，我们在涉及真钞和假钞的重复钞票认证任务中监测眼球运动。虽然在鉴定决定之前，注视点广泛分布在整个笔记中，但很明显，人们倾向于难以模仿的区域，并避免容易模仿的区域。然而，有一个强烈的倾向，最初固定的钞票的肖像，只有在此之后，眼球运动控制似乎更具有战略意义。那些将更多的注视点指向难以模仿的区域，并抵制更容易模仿的区域的人在真实性任务中表现得更好。部署战略固定的趋势随着经验的增加而改善，这表明认证受益于精确的视觉定位和精细的分类标准。
Authentication is an important cognitive process used to determine whether one’s initial identification of an object is corroborated by additional sensory information. Although authentication is critical for safe interaction with many objects, including food, websites, and valuable documents, the visual orienting strategies used to garner additional sensory data to support authentication remain poorly understood. When reliable visual cues to counterfeit cannot be anticipated, distributing fixations widely across an object’s surface might be useful. However, strategic fixation of specific object-defining attributes would be more efficient and should lead to better authentication performance. To investigate, we monitored eye movements during a repetitive banknote authentication task involving genuine and counterfeit banknotes. Although fixations were distributed widely across the note prior to authentication decisions, preference for hard-to mimic areas and avoidance of easily mimicked areas was evident. However, there was a strong tendency to initially fixate the banknote’s portrait, and only thereafter did eye movement control appear to be more strategic. Those who directed a greater proportion of fixations at hard-to-mimic areas and resisted more easily mimicked areas performed better on the authenticity task. The tendency to deploy strategic fixation improved with experience, suggesting that authentication benefits from precise visual orienting and refined categorisation criteria.
