项目摘要
It is often said that humans are visual animals, but there is little doubt that our exceptional capacity for social
communication is auditory-vocal in nature. Importantly, this capacity is not limited to conversational speech, but
is also utilized in more abstract aspects of sound ranging over proselytizing, poetry, repetitive chant, and music.
A core feature of this speech-music continuum is the ability to convey affect through sound – made possible by
an auditory-vocal functionality that has evolved to reflexively attribute affect to voice-like stimuli. A system for
processing auditory-vocal affect is critical to human social behavior: its refinement predicts social fluency, as
individuals who are skilled at sharing in affect tend to be more socially integrated; and its impairment predicts
social deficits, e.g., in autism spectrum disorder (ASD), schizophrenia, and major depressive disorder. Despite
its central role in social behavior, we lack insight into the neurobiology that underlies the processing of auditory-
vocal affect and why it fails to operate normally in prominent brain disorders. This gap in knowledge is directly
related to the absence of a psychometrically robust, objective, and efficient assay, i.e., a “gold standard” test of
Auditory-Vocal Affect. Accordingly, Aim 1 of this proposal is to develop a gold standard Test of Auditory-Vocal
Affect (the “TAVA”) and collect large-scale normative data to support it. To do so I will: (a) use a combination of
carefully designed speech and music stimuli to overcome obstacles faced by previous tests and tease apart
issues of language processing from a core impairment in auditory-vocal affect processing; and (b) deploy the
TAVA online. Aim 2 tests whether the TAVA can accurately discriminate adults with ASD from neurotypical adults
in a controlled laboratory study. And Aim 3 tests whether a single-dose of intranasally administered oxytocin vs.
placebo can “move the needle” on TAVA performance in ASD, as implicated in previous studies of affect
processing and ASD. My overarching hypothesis is that impairment in auditory-vocal affect functionality is a
fundamental but poorly defined dimension of the core social deficits that define ASD. My rationale is that deficits
in the perception of affect in speech are repeatedly described in ASD but, in contrast to visuo-facial affect, remain
under-interrogated and poorly understood. If I am successful, I will have defined a new standard for assessing
auditory-vocal affect functionality, suitable for behavioral phenotyping and as an objective assessment in ASD
specifically and in clinical research more generally. Furthermore, my results will provide a foundation for future
investigations into the neurobiological bases of auditory-vocal affect that promises to define their contribution to
social function and dysfunction in mental health. Finally, the research goals outlined here synergize with a
training plan that fills critical gaps in my basic science background. Specifically, I seek to acquire skills in
neuroendocrinology, clinical research, and advanced statistical methods that will allow me to apply my
interdisciplinary background in auditory-vocal communication – focused on speech, music, and affect – to
relevant problems in mental health research as I transition to research independence.
人们常说,人类是视觉动物,但毫无疑问,我们非凡的社交能力,
沟通本质上是语音沟通。重要的是,这种能力不仅限于会话语音,
也被用于更抽象的声音方面,包括传教、诗歌、重复的圣歌和音乐。
这种语音-音乐连续体的一个核心特征是通过声音传达情感的能力,
这是一种本能的发声功能,已经进化到反射性地将影响归因于类似声音的刺激。的系统
处理语音情感对人类的社会行为至关重要:它的精细化预测了社会流畅性,
善于分享情感的人往往更能融入社会,而这种缺陷预示着
社会赤字,例如,自闭症谱系障碍(ASD)、精神分裂症和重度抑郁症。尽管
它在社会行为中的核心作用,我们缺乏对神经生物学的洞察力,这是听觉处理的基础,
声音的影响,以及为什么它不能正常运作,在突出的大脑疾病。这种知识上的差距,
与缺乏心理测量学上稳健、客观和有效的测定有关,即,“黄金标准”测试
听觉-声音影响。因此,本研究的目的之一是开发一个金标准的听觉-发声测试,
影响(“TAVA”),并收集大规模的规范性数据来支持它。
精心设计的语音和音乐刺激,以克服以前的测试所面临的障碍,
