与低频率的哭泣相比，高频率的哭泣被认为更令人厌恶和痛苦。此外，先前的研究推测，在患有自闭症谱系障碍（ASD）的儿童中，较高的f0可能是引起照顾者精神状态不安的原因。此外，文献中没有关于婴儿期ASD中f0发育轨迹的证据。本研究调查了50例ASD患儿与正常发育（TD）患儿和其他发育迟缓（DD）患儿哭闹的发展轨迹。采用了两项研究。在研究1中，使用标准化的声学分析方案，对30名TD儿童（5个月、13个月和20个月）进行了纵向随访，并分析了他们的50次哭泣。在研究2中，声学分析应用于30名ASD， TD和DD儿童在5个月和18个月时的回顾性家庭视频中的哭泣事件。使用标准程序和回顾性程序，发现第一年和第二年之间TD儿童的f0下降。此外，虽然在TD和DD儿童中，f0轨迹存在变化，但在ASD中没有明显变化。在ASD中，较高的f0可能解释了照顾者对哭泣的偏见，引起精神上的不安，并可能干扰父母反应的适当性。描述了研究的局限性和未来的目标。
Episodes of crying with higher fundamental frequency (f0) are perceived as more aversive and distressful than lower frequency cries. Besides, previous studies have speculated that in children with Autism Spectrum Disorder (ASD) higher f0 may account for evoking mental states of uneasiness in the caregiver. Moreover no evidence on developmental trajectory of f0 in ASD in infancy is present in literature. This research investigated: developmental trajectory of f0 of episodes of crying in children with ASD as opposed to typically developing (TD) children and children with other developmental delay (DD). Two studies were employed. In Study 1, using a standardised protocol for acoustic analysis a group of 30 TD children was followed longitudinally (five, 13 and 20 months) and f0 of their episodes of crying was analysed. In Study 2, acoustic analysis was applied to episodes of crying selected from retrospective home videos of 30 children with ASD, TD and DD at five and 18 months. Decrease of f0 in TD children between the first and second year both using a standard procedure and the retrospective procedure was found. Besides while in TD and DD children a change of the f0 trajectory was present, no changes were evident in ASD. Higher f0 may account in ASD for a caregiver bias in their interpretation of crying, evoking mental states of uneasiness and it may interfere with the adequacy of the parental response. Limitations and future goal of the research are described.
