About a hundred!<\/p><p style=\"font-weight: 400;\">The motor system, the set of neural circuits that control our muscles, thus plays an essential role in our ability to communicate orally. Does the motor system change as we age? To find out, 60 healthy participants, aged 18 to 83, came to our lab to perform a task. The task in question? Reading aloud a series of non-words, that is, words without meaning (e.g., <em>difeli<\/em>). Participants\u2019 response time and response duration were measured, and participants\u2019 error rate was calculated after 2 referees listened to the vocal recordings.<\/p><p style=\"font-weight: 400;\">The results, which were published in the journal <em>Psychology &amp; Aging<\/em>, show a decrease in the accuracy of the produced non-words and an increase in their duration with age. These results suggest a decline in the planning and execution of muscular movements related to speech production. These findings, coupled with those of additional studies from our lab, point to a possible link between the decline in speech production with age and brain aging, especially within the motor system.<\/p><p style=\"font-weight: 400;\">Further studies are needed to clarify the nature and scope of brain aging in the planning and execution of motor commands.<\/p><p style=\"font-weight: 400;\">Link to the article: <a href=\"https:\/\/speechneurolab.ca\/wp-content\/uploads\/2022\/05\/Tremblay_etal_2018_PsychAging.pdf\">https:\/\/speechneurolab.ca\/wp-content\/uploads\/2022\/05\/Tremblay_etal_2018_PsychAging.pdf<\/a><\/p><p style=\"font-weight: 400;\">Image credit: ahmedgad\/Pixabay<\/p><p>Suggested readings:<\/p><ul><li><a href=\"https:\/\/speechneurolab.ca\/en\/aging-and-brain-volume\/\">Aging and brain volume<\/a><\/li><li><a href=\"https:\/\/speechneurolab.ca\/en\/production-de-la-voix\/\">Voice production<\/a><\/li><li><a href=\"https:\/\/speechneurolab.ca\/en\/analyses-du-langage-parle\/\">Speech analysis<\/a><\/li><li><a href=\"https:\/\/speechneurolab.ca\/en\/parole-et-trompette\/\">Speech production and trumpet<\/a><\/li><li><a href=\"https:\/\/speechneurolab.ca\/en\/comic-strip-about-speech\/\">Comic strip about speech<\/a><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-40e01e9 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"40e01e9\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-354bb99\" data-id=\"354bb99\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Speech production \u2013 the act of speaking \u2013 is a process so ingrained in us, so effortless, that we forget its great complexity.
