Referred to as statistical learning (SL), this process is particularly critical when learning a spoken language, helping in the identification of discrete words within a spoken phrase. Here, by considering individual differences in speech auditory\u2013motor synchronization, we demonstrate that recruitment of a specific neural network supports behavioral differences in SL from speech. While independent component analysis (ICA) of fMRI data revealed that a network of auditory and superior pre\/motor regions is universally activated in the process of learning, a frontoparietal network is additionally and selectively engaged by only some individuals (high auditory\u2013motor synchronizers). Importantly, activation of this frontoparietal network is related to a boost in learning performance, and interference with this network via articulatory suppression (AS; i.e., producing irrelevant speech during learning) normalizes performance across the entire sample. Our work provides novel insights on SL from speech and reconciles previous contrasting findings. These findings also highlight a more general need to factor in fundamental individual differences for a precise characterization of cognitive phenomena.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<p><strong><a href=\"https:\/\/doi.org\/10.1371\/journal.pbio.3001712\" target=\"_blank\" rel=\"noreferrer noopener\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">https:\/\/doi.org\/10.1371\/journal.pbio.3001712<\/mark><\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Joan Orpella, M Florencia Assaneo, Pablo Ripoll\u00e9s, Laura Noejovich, Diana L\u00f3pez-Barroso, Ruth de Diego-Balaguer, David Poeppel PLoS biology (2022)<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[11],"tags":[19,18,55,22,21,17,56,20,28,23],"_links":{"self":[{"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/posts\/359"}],"collection":[{"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/comments?post=359"}],"version-history":[{"count":2,"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/posts\/359\/revisions"}],"predecessor-version":[{"id":361,"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/posts\/359\/revisions\/361"}],"wp:attachment":[{"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/media?parent=359"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/categories?post=359"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/132.248.142.13\/assaneo\/wp-json\/wp\/v2\/tags?post=359"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
