Image inversion is a powerful tool for investigating cognitive mechanisms of visual perception. However, studies have mainly used inversion in paradigms presented on twodimensional computer screens. It remains open whether disruptive effects of inversion also hold true in more naturalistic scenarios. In our study, we used scene inversion in virtual reality in combination with eye tracking to investigate the mechanisms of repeated visual search through three-dimensional immersive indoor scenes. Scene inversion affected all gaze and head measures except fixation durations and saccade amplitudes. Our behavioral results, surprisingly, did not entirely follow as hypothesized: While search efficiency dropped significantly in inverted scenes, participants did not utilize more memory as measured by search time slopes. This indicates that despite the disruption, participants did not try to compensate the increased difficulty by using more memory. Our study highlights the importance of investigating classical experimental paradigms in more naturalistic scenarios to advance research on daily human behavior.
图像倒置是研究视觉感知认知机制的有力工具。然而，以往研究主要在二维电脑屏幕呈现的范式中使用倒置。在更自然的场景中，倒置的干扰效应是否同样成立仍不明确。在我们的研究中，我们在虚拟现实中结合眼动追踪使用场景倒置，以探究在三维沉浸式室内场景中重复视觉搜索的机制。场景倒置影响了除注视持续时间和扫视幅度之外的所有注视和头部指标。令人惊讶的是，我们的行为结果并未完全如假设那样：虽然在倒置场景中搜索效率显著下降，但参与者并未如通过搜索时间斜率所测量的那样利用更多记忆。这表明尽管存在干扰，参与者并未试图通过使用更多记忆来补偿增加的难度。我们的研究强调了在更自然的场景中研究经典实验范式对于推进日常人类行为研究的重要性。
