基于持续时间的听觉分组偏好可能是由成人和婴儿的语言经验形成的，而不像基于强度的分组，它受一个普遍的偏置的软偏好的支配。有人提出，基于时长的节奏分组偏好发展为母语短语韵律的函数。另外，已经提出短语韵律支持句法获取（例如，短语内词序的韵律引导）。在目前的研究中，使用一个看偏好的程序，9至10个月大的西班牙语为主和巴斯克语为主的双语婴儿的节奏偏好，以响应非语言音调交替的持续时间或强度进行了评估。在基于强度的条件下，语言经验没有影响。然而，在持续时间为基础的条件下，婴儿表现出分组模式预测的短语韵律的主导输入。考虑到所提出的句法自举和感知音调分组之间的联系，我们的总体结果表明，句法习得（例如，学习词序规则）是由不同的听觉感知机制支持的，对于婴儿的双语输入中的主导句法，而不是对于次要句法。
Duration-based auditory grouping preferences are presumably shaped by language experience in adults and infants, unlike intensity-based grouping that is governed by a universal bias of a loud-soft preference. It has been proposed that duration-based rhythmic grouping preferences develop as a function of native language phrasal prosody. Additionally, it has been suggested that phrasal prosody supports syntax acquisition (e.g., prosodic bootstrapping of word order within phrases). Using a looking preference procedure, in the current study, 9-to-10-month-old Spanish-dominant and Basque-dominant bilingual infants’ rhythmic preferences in response to nonlinguistic tones alternating in duration or intensity were assessed. In the intensity-based condition no effects of language experience was present. In the duration-based condition, however, infants exhibited grouping patterns as predicted by the phrasal prosody of their dominant input. Considering the proposed link between syntactic bootstrapping and perceptual tone grouping, our overall results suggest that syntax acquisition (e.g., learning the rules of word order) is supported by different auditory perceptual mechanisms for the dominant syntax than for the less dominant syntax in the infant's dual language input.
