But <strong>disfluencies do not occur randomly<\/strong>. Instead, &#8216;uh&#8217; typically occurs before &#8216;hard-to-name&#8217; low-frequency words (&#8216;uh&#8230; automobile&#8217;). Previous experiments led by Hans Rutger Bosker from the Max Planck Institute for Psycholinguistics have shown that people can use disfluencies to predict upcoming low-frequency words. But Bosker and his colleagues went one step further. They tested <strong>whether listeners would actively track the occurrence of &#8216;uh&#8217;, even when it appeared in unexpected places<\/strong>.<\/p>\n<div id=\"text\">\n<p><strong>Click on uh&#8230; the igloo<\/strong><\/p>\n<p>The researchers used eye-tracking, which measures people&#8217;s looks towards objects on a screen. Two groups of Dutch participants saw two images on a screen (for instance, a hand and an igloo) and heard both fluent and disfluent instructions. However, one group heard a &#8216;typical&#8217; talker say &#8216;uh&#8217; before &#8216;hard-to-name&#8217; low-frequency words (&#8220;Click on uh&#8230; the igloo&#8221;), while the other group heard an &#8216;atypical&#8217; talker saying &#8216;uh&#8217; before &#8216;easy-to-name&#8217; high-frequency words (&#8220;Click on uh&#8230; the hand&#8221;). Would people in this second group track the unexpected occurrences of &#8216;uh&#8217; and learn to look at the &#8216;easy-to-name&#8217; object?<\/p>\n<p>As expected, participants listening to the &#8216;typical&#8217; talker already looked at the igloo upon hearing the disfluency (&#8216;uh&#8217;&#8230;; that is well before hearing &#8216;igloo&#8217;). Interestingly, people listening to the &#8216;atypical&#8217; talker learned to adjust this &#8216;natural&#8217; prediction. Upon hearing a disfluency (&#8216;uh&#8217;&#8230;), they learnt to look at the common object, even before hearing the word itself (&#8216;hand&#8217;). &#8220;We take this as evidence that <strong>listeners actively keep track of when and where talkers say &#8216;uh&#8217; in spoken communication, adjusting what they predict will come next for different talkers<\/strong>,&#8221; concludes Bosker.<\/p>\n<p><strong>Speakers with a foreign accent<\/strong><\/p>\n<p>Would listeners also adjust their expectations with a non-native speaker? In a follow-up experiment, the same sentences were spoken by someone with a heavy Romanian accent. In this experiment, participants did learn to predict uncommon objects from a &#8216;typical&#8217; non-native talker (saying &#8216;uh&#8217; before low-frequency words). However, they did not learn to predict high-frequency referents from an &#8216;atypical&#8217; non-native talker (saying &#8216;uh&#8217; before high-frequency words) &#8212; even though the sentence materials were the same in the native vs. non-native experiment.<\/p>\n<p>Geertje van Bergen, co-author on the paper, explains: &#8220;This probably indicates that hearing a few atypical disfluent instructions (e.g., the non-native talker saying &#8216;uh&#8217; before common words like &#8220;hand&#8221; and &#8220;car&#8221;) led listeners to infer that the non-native speaker had difficulty naming even simple words in Dutch. As such, they presumably took the non-native disfluencies to not be predictive of the word to follow &#8212; in spite of the clear distributional cues indicating otherwise.&#8221; This finding is interesting, as it reveals an interplay between &#8216;disfluency tracking&#8217; and &#8216;pragmatic inferencing&#8217;: we only track disfluencies if we infer from the talker&#8217;s voice that the talker is a &#8216;reliable&#8217; uhm&#8217;er.<\/p>\n<p><strong>A hot topic in psycholinguistics<\/strong><\/p>\n<p>According to the authors, this is the <strong>first evidence of distributional learning in disfluency processing<\/strong>. &#8220;We&#8217;ve known about disfluencies triggering prediction for more than 10 years now, but we demonstrate that these predictive strategies are malleable. People actively track when particular talkers say &#8216;uh&#8217; on a moment by moment basis, adjusting their predictions about what will come next,&#8221; explains Bosker. Distributional learning has been a hot topic in psycholinguistics the past few years. &#8220;We extend this field with evidence for distributional learning of metalinguistic performance cues, namely disfluencies &#8212; highlighting the wide scope of distributional learning in language processing.&#8221;<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Max Planck Institute for Psycholinguistics press release: Spontaneous conversation is riddled with disfluencies such as pauses and &#8216;uhm&#8217;s: on average people produce 6 disfluencies every 100 words.
