Led by Dr Merideth Gattis, the year-long research involved 84 babies aged 14 to 18 months who took part in two studies \u2013 one using English language and one using Greek language.<\/p>\n The infants watched a researcher perform actions with toys that were either intentional or accidental. These actions were accompanied by the words “whoops” and “there” which each had distinct vocal contours and acted as clues for both intention and meaning. The same process was repeated in Greek. This time the toddlers would only get clues about intention from tone alone, not from the word\u2019s meaning \u2013 none of them had been exposed to the Greek language previously.<\/p>\n Dr Gattis and her research partner Dr Elena Sakkalou from University College London found that the infants copied intentional actions more than accidental actions, and were equally likely to copy intentional actions in both studies, suggesting that infants do not need lexical or facial cues to infer intentions.<\/p>\n Their work adds to a growing body of research into the role of tone, or prosody, in infancy. Importantly it reveals that infants are able to differentiate between intentional and accidental actions through tone alone, helping them to not only process information about another person\u2019s intention but to build a picture of how to act in the world<\/strong>.<\/p>\n Speaking about their findings, Dr Gattis said: “Understanding mental states, such as intentions, desires, and beliefs, is one of the most important human abilities. Psychologists still know very little about how infants begin to build this understanding. In this research we aimed to investigate the contribution of prosodic cues, or tone of voice, to infants\u2019 understanding of mental states. Tone of voice is a really useful signal to what someone is thinking. We used the words \u2018whoops\u2019 and \u2018there\u2019 accompanied by relative vocal inflections in two languages and got exactly the same results \u2013 whether in English or Greek, which none of the children understood.<\/p>\n “This study showed us that children can judge the intentions of other people based on tone of voice alone<\/strong>. The acoustic features of speech accompanying actions allow infants to identify intention in perceptually similar actions. They are able to use prosodic cues as a guide to how to act on the world, demonstrated by their tendency to copy intentional actions more than accidental actions.<\/strong>”<\/p>\n The research \u2013 Infants infer intentions from prosody<\/em> – is published in the journal Cognitive Development.<\/em><\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the Cardiff University press release via MedicalXPress: Infants can understand the difference between intentional and accidental actions from tone of voice alone, new research by the Cardiff University School… Read more »<\/a><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[9],"tags":[78,45,13,74,25],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/691"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=691"}],"version-history":[{"count":1,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/691\/revisions"}],"predecessor-version":[{"id":692,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/691\/revisions\/692"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=691"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=691"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=691"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"http:\/\/therapytoronto.ca\/images\/blogpics\/Baby.jpg\" "\\"baby\\"")
Infants can understand the difference between intentional and accidental actions from tone of voice alone<\/strong>, new research by the Cardiff University School of Psychology has shown.<\/p>\n
