The most common experimental paradigm to study its largely unknown underlying mechanisms is the paced finger tapping task, where a subject taps to a periodic sequence of brief tones. Contrary to reaction time, this task involves temporal prediction because the subject needs to trigger the motor action in advance in order for the tap and the next stimulus to occur simultaneously, and an error correction mechanism takes the past performance as input to adjust the following prediction. In a different temporal task, it has been shown that exposure to a distribution of temporal intervals creates a \u0093temporal context\u0094 that can bias the estimation\/production of a single target interval. As temporal estimation and production are also involved in SMS, we asked whether a paced finger tapping task would show any temporal context effect. In this work we show that temporal context can indeed be generated in a paced finger tapping task via period perturbations, and that the shape and size of the resynchronization curve (synchrony error as a function of stimulus number) depends on the temporal context. We conclude that the underlying error correction mechanism in SMS depends on the temporal context in much the same way as in other, simpler temporal tasks.<\/p>\n","protected":false},"excerpt":{"rendered":" Author: Silva Ariel Dario | email: arieldario.silva83@gmail.com | Sensory and Motor Systems<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[17],"tags":[27],"class_list":["post-1359","post","type-post","status-publish","format-standard","hentry","category-session-1","tag-sensory-and-motor-systems"],"_links":{"self":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1359","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/comments?post=1359"}],"version-history":[{"count":3,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1359\/revisions"}],"predecessor-version":[{"id":1853,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1359\/revisions\/1853"}],"wp:attachment":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/media?parent=1359"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/categories?post=1359"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/tags?post=1359"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
