Abstract:
Over the last two decades, the analogue report task has become a standard method for measuring the fidelity of visual representations across research domains including perception, attention, and memory. Despite its widespread use, there has been no methodical investigation of the different task parameters that might contribute to response variability. To address this gap, we conducted two experiments manipulating components of a typical analogue report test of memory for colour hue. We found that human response errors were independently affected by changes in storage and maintenance requirements of the task, demonstrated by a strong effect of set size even in the absence of a memory delay. In contrast, response variability remained unaffected by physical size of the colour wheel, implying negligible contribution of motor noise to task performance, or by its chroma radius, highlighting non-uniformity of the standard colour space. Comparing analogue report to a matched forced-choice task, we found variation in adjustment criterion made a limited contribution to analogue report variability, becoming meaningful only with low representational noise. Our findings validate the analogue report task as a robust measure of representational fidelity for most purposes, while also quantifying non-representational sources of noise that would limit its reliability in specialized settings.
摘要:
在过去的二十年里,模拟报告任务已成为测量跨研究领域的视觉表示的保真度的标准方法,包括感知,注意,和记忆。尽管它广泛使用,没有对可能导致反应变异性的不同任务参数进行系统的研究。为了解决这个差距,我们进行了两个实验,操作了典型的色调记忆模拟报告测试的组成部分。我们发现,人为响应错误受到任务存储和维护要求变化的独立影响,即使在没有内存延迟的情况下,集合大小也具有很强的效果。相比之下,响应变异性不受色轮物理大小的影响,暗示电机噪声对任务性能的贡献微不足道,或其色度半径,突出标准颜色空间的非均匀性。将模拟报告与匹配的强制选择任务进行比较,我们发现调整标准的变化对模拟报告变异性的贡献有限,只有在低代表性噪声的情况下才变得有意义。我们的发现验证了模拟报告任务是大多数目的的代表性保真度的可靠度量,同时还量化了非代表性的噪声源,这将限制其在特殊环境中的可靠性。
