项目摘要

Every human culture creates music, which drives a multi-billion-dollar industry worldwide. The societal impact is also important, as music is tightly linked to social bonding. For groups of individuals, making music together can promote empathy and cooperative behavior. The positive experience of music is known to depend, in part, on predictability (the knowledge of what comes next). However, little is known about how predictable musical features (e.g., melody, harmony, and rhythm) come to be rewarding. This CAREER award uses an unfamiliar tonal system to explore how people learn to respond to novel acoustic relationships. More generally, it evaluates the roles of prediction and reward in auditory learning.Previous work exploring how people learn to respond to structured sequences of auditory stimuli have exposed participants to novel features and then monitored changes in subjective ratings of reward value. However, even new compositions use familiar structural features, which activate a large knowledge base of predictions acquired implicitly throughout our lives. This poses a serious confound to the study of prediction and reward. To circumvent this challenge, the investigator will use a novel system, known as the Bohlen-Pierce scale. By exposing participants to novel, acoustically controlled sounds, the investigator can test whether reward value can be acquired solely from newly formed predictions. The investigator will also compare how typical listeners and listeners with one of two auditory/perceptual disorders (amusia and anhedonia) learn novel sound patterns. The overall aim is to understand the dual roles of repetition and variation of sound patterns in driving learning, memory, and reward. The work merges perceptual testing, functional MRI, and neuropsychological testing with sound design. These activities will be integrated with an educational plan to develop a unique Bachelor of Science degree program.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

每一种人类文化都创造音乐，音乐在全球范围内推动着数十亿美元的产业。社会影响也很重要，因为音乐与社会关系紧密相连。对于一群人来说，一起创作音乐可以促进同理心和合作行为。众所周知，音乐的积极体验部分取决于可预测性（对接下来会发生什么的了解）。然而，对于可预测的音乐特征（如旋律、和声和节奏）是如何产生回报的，我们知之甚少。这个职业奖使用一个不熟悉的音调系统来探索人们如何学习对新的声学关系做出反应。更一般地说，它评估了预测和奖励在听觉学习中的作用。先前的研究探索了人们如何学会对结构化的听觉刺激序列做出反应，让参与者接触到新的特征，然后监测他们对奖励价值的主观评分的变化。然而，即使是新的作品也使用熟悉的结构特征，这激活了我们一生中隐性获得的大量预测知识库。这给预测和奖励的研究带来了严重的混乱。为了规避这一挑战，研究人员将使用一种称为Bohlen-Pierce量表的新系统。通过让参与者听到新奇的、声学控制的声音，研究者可以测试是否奖励价值可以仅仅从新形成的预测中获得。研究者还将比较典型的听众和患有两种听觉/知觉障碍（失音症和快感缺乏症）的听众如何学习新的声音模式。总体目标是理解声音模式的重复和变化在驱动学习、记忆和奖励中的双重作用。这项工作将感知测试、功能性MRI和神经心理学测试与声音设计结合起来。这些活动将与一个教育计划相结合，以发展一个独特的理学学士学位课程。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
