显然，人们可以学习一种新的感官技能——一种将感官输入映射到世界状态的新方法。目前尚不清楚新的感官技能如何灵活地融入多感官感知和决策中。为了解决这个问题，我们训练视力正常的参与者（N = 12）使用新的类似回声的听觉提示以及嘈杂的视觉提示来确定虚拟世界中的距离。使用基于模型的分析，我们测试了使用新技能进行高效多感官感知和决策的关键标志。我们发现 14 名参与者中有 12 人学会了使用新颖的听觉提示来判断距离。他们对这种新感官技能的使用显示出三个关键特征：（a）它提高了定时决策的速度；（b）它在很大程度上抵抗了同时数字跨度任务的干扰； (c) 它以类似贝叶斯的方式与视觉集成以提高精度。我们还展示了这种相对较短的训练后的一些限制：精度收益低于贝叶斯最优预测，并且没有强制信号融合。我们得出的结论是，经过短期培训，人们已经将新的感官技能融入到灵活的多感官感知和决策中。这些见解的一个关键应用是开发感官增强系统，以新颖的方式增强人类的感知能力。我们揭示的局限性（次优、缺乏融合）为进一步研究这些能力的局限性及其大脑基础提供了基础。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）
It is clear that people can learn a new sensory skill—a new way of mapping sensory inputs onto world states. It remains unclear how flexibly a new sensory skill can become embedded in multisensory perception and decision-making. To address this, we trained typically sighted participants (N= 12) to use a new echo-like auditory cue to distance in a virtual world, together with a noisy visual cue. Using model-based analyses, we tested for key markers of efficient multisensory perception and decision-making with the new skill. We found that 12 of 14 participants learned to judge distance using the novel auditory cue. Their use of this new sensory skill showed three key features:(a) It enhanced the speed of timed decisions;(b) it largely resisted interference from a simultaneous digit span task; and (c) it integrated with vision in a Bayes-like manner to improve precision. We also show some limits following this relatively short training: Precision benefits were lower than the Bayes-optimal prediction, and there was no forced fusion of signals. We conclude that people already embed new sensory skills in flexible multisensory perception and decision-making after a short training period. A key application of these insights is to the development of sensory augmentation systems that can enhance human perceptual abilities in novel ways. The limitations we reveal (sub-optimality, lack of fusion) provide a foundation for further investigations of the limits of these abilities and their brain basis.(PsycInfo Database Record (c) 2023 APA, all rights reserved)
