In studies of perceptual and neural processing differences between musicians and nonmusicians, participants are typically dichotomized on the basis of personal report of musical experience. The present study relates self-reported musical experience and objectively measured musical aptitude to a skill that is important in music perception: temporal resolution (or acuity). The Advanced Measures of Music Audiation (AMMA) test was used to objectively assess participant musical aptitude, and adaptive psychophysical measurements were obtained to assess temporal resolution on two tasks: within-channel gap detection and across-channel gap detection. Results suggest that musical aptitude measured with the AMMA and self-reporting of music experiences (duration of music instruction) are both related to temporal resolution ability in musicians. The relationship between musical aptitude and/or duration of music training is important to music educators advocating for the benefits of music programs as well as in behavioral and neurophysiological research.

跨渠道听觉差距检测

在音乐家和非音乐家之间的感知和神经处理差异的研究中，参与者通常根据个人对音乐体验的报告进行二分法。本研究将自我报告的音乐体验和客观测量的音乐能力与对音乐感知很重要的一项技能联系起来：时间分辨率（或敏锐度）。音乐听力高级测量 (AMMA) 测试用于客观评估参与者的音乐能力，并获得自适应心理物理测量来评估两个任务的时间分辨率：通道内间隙检测和跨通道间隙检测。结果表明，用 AMMA 测量的音乐能力和音乐体验的自我报告（音乐教学的持续时间）都与音乐家的时间分辨能力有关。
