Multisensory cue combination during navigation is examined for the relative use and integration of different sensory spatial cues, but the reliability of cue combination metrics has not yet been characterized. We quantify the test-retest reliability of three metrics (accuracy, variability, predicted cue-weighting) used in studies of sensory cue combination for spatial updating. Participants completed a triangular homing task in immersive virtual reality comprising three cue conditions - visual cues-only, self-motion cues-only, and visual + self-motion cues - in two sessions separated by an average 11-day interval. We found strong test-retest reliability of homing accuracy with two sensory cues but poor reliability of accuracy when only one sensory cue was available. Homing variability and predicted cue-weighting showed poor test-retest reliability across all conditions.
在导航过程中对多感官线索组合进行了研究，以考察不同感官空间线索的相对使用和整合情况，但线索组合指标的可靠性尚未得到描述。我们量化了用于空间更新的感官线索组合研究中的三个指标（准确性、变异性、预测线索权重）的重测信度。参与者在沉浸式虚拟现实中完成了一项三角形归巢任务，该任务包括三种线索条件——仅视觉线索、仅自我运动线索以及视觉 + 自我运动线索——分两个阶段进行，两个阶段之间平均间隔11天。我们发现，在有两种感官线索时归巢准确性具有很强的重测信度，但当只有一种感官线索可用时，准确性的信度较差。在所有条件下，归巢变异性和预测线索权重的重测信度都较差。
