It is a motor skill that requires them to learn to coordinate multiple muscles of varying function across their body. This coordination is directly linked to ongoing fluctuations in heart rate.\u00a0<\/p>\n<p>Borjon investigated whether these fluctuations in heart rate coincide with vocal production and word production in 24-month-old babies.<\/p>\n<p>He found that heart rate fluctuations align with the timing of vocalizations and are associated with their duration and the likelihood of producing recognizable speech.\u00a0<\/p>\n<p>\u201cHeart rate naturally fluctuates in all mammals, steadily increasing then decreasing in a rhythmic pattern. It turns out infants were most likely to make a vocalization when their heart rate fluctuation had reached a local peak (maximum) or local trough (minimum),\u201d reports Borjon.<\/p>\n<p>\u201cVocalizations produced at the peak were longer than expected by chance. Vocalizations produced just before the trough, while heart rate is decelerating, were more likely to be recognized as a word by na\u00efve listeners.\u201d\u00a0<\/p>\n<p>Borjon and team measured a total of 2,708 vocalizations emitted by 34 infants between 18 and 27 months of age while the babies played with a caregiver.<\/p>\n<p>Infants in this age group typically don\u2019t speak whole words yet, and only a small subset of the vocalizations could be reliably identified as words by naive listeners (10.3%). For the study, the team considered the heart rate dynamics of all sounds made by the baby\u2019s mouth, be it a laugh, a babble or a coo.<\/p>\n<p>\u201cEvery sound an infant makes helps their brain and body learn how to coordinate with each other, eventually leading to speech,\u201d Borjon said.\u00a0<\/p>\n<p>As infants grow, their autonomic nervous system \u2014 the part of the body that controls functions like heart rate and breathing \u2014 grows and develops. The first few years of life are marked by significant changes in how the heart and lungs function, and these changes continue throughout a person\u2019s life.\u00a0<\/p>\n<p>\u201cThe relationship between recognizable vocalizations and decelerating heart rate may imply that the successful development of speech partially depends on infants experiencing predictable ranges of autonomic activity through development.\u00a0<\/p>\n<p>\u201cUnderstanding how the autonomic nervous system relates to infant vocalizations over development is a critical avenue of future research for understanding how language emerges, as well as risk factors for atypical language development,\u201d said Borjon\u00a0<\/p>\n<h2 class=\"wp-block-heading\">About this language and neurodevelopment research news<\/h2>\n<p class=\"has-background\" style=\"background-color:#ffffe8\"><strong>Author: <\/strong><a href=\"http:\/\/neurosciencenews.com\/cdn-cgi\/l\/email-protection#1a767b7c737971777b745a6f72347f7e6f\" target=\"_blank\" rel=\"noreferrer noopener\">Laurie Fickman<\/a><br \/><strong>Source: <\/strong><a href=\"https:\/\/uh.edu\" target=\"_blank\" rel=\"noreferrer noopener\">University of Houston<\/a><br \/><strong>Contact: <\/strong>Laurie Fickman \u2013 University of Houston<br \/><strong>Image: <\/strong>The image is credited to Neuroscience News<\/p>\n<p class=\"has-background\" style=\"background-color:#ffffe8\"><strong>Original Research: <\/strong>Open access.<br \/>\u201c<a href=\"https:\/\/doi.org\/10.1073\/pnas.2419650121\" target=\"_blank\" rel=\"noreferrer noopener\">Recognizability and timing of infant vocalizations relate to fluctuations in heart rate<\/a>\u201d by Jeremy I.
