A classic paradigm used to quantify the perceptual weighting of binaural spatial cues requires a listener to adjust the value of one cue, while the complementary cue is held constant. Adjustments are made until the auditory percept appears centered in the head, and the values of both cues are recorded as a trading relation (TR), most commonly in μs interaural time difference per dB interaural level difference. Interestingly, existing literature has shown that TRs differ according to the cue being adjusted. The current study investigated whether cue-specific adaptation, which might arise due to the continuous, alternating presentation of signals during adjustment tasks, could account for this poorly understood phenomenon. Three experiments measured TRs via adjustment and via lateralization of single targets in virtual reality (VR). Targets were 500 Hz pure tones preceded by silence or by adapting trains that held one of the cues constant. VR removed visual anchors and provided an intuitive response technique during lateralization. The pattern of results suggests that adaptation can account for cue-dependent TRs. In addition, VR seems to be a viable tool for psychophysical tasks.

双耳空间适应作为耳间时间和电平差异的不对称交易的机制。


用于量化双耳空间线索的感知权重的经典范式要求听者调整一个线索的值，同时保持补充线索不变。进行调整，直到听觉感知出现在头部的中心，并且两个线索的值被记录为交易关系（TR），最常见的是μs耳间时间差每dB耳间电平差。有趣的是，现有文献表明，TR 根据所调整的提示而有所不同。目前的研究调查了因在调整任务期间连续、交替地呈现信号而可能出现的线索特异性适应是否可以解释这种人们知之甚少的现象。三个实验通过虚拟现实 (VR) 中单个目标的调整和横向化来测量 TR。目标是 500 Hz 纯音，然后是沉默或调整列车以保持其中一个提示不变。 VR 消除了视觉锚点，并在侧化过程中提供了直观的响应技术。结果模式表明，适应可以解释线索依赖性 TR。此外，虚拟现实似乎是心理物理任务的可行工具。
