Dialogue: 0,0:00:11.45,0:00:17.00,Default,,0000,0000,0000,,My name is Xaver Funk, and I recently had\Nthe chance to really [involve] myself into Dialogue: 0,0:00:17.16,0:00:20.45,Default,,0000,0000,0000,,this topic, because I am studying\Nneurosciences and this was kind of Dialogue: 0,0:00:20.45,0:00:26.03,Default,,0000,0000,0000,,something that I had to do. And, yeah,\Nthat's what I want to share with you today. Dialogue: 0,0:00:26.48,0:00:32.57,Default,,0000,0000,0000,,So, what I have been doing recently also,\Nis learning arabic, and a little bit of Dialogue: 0,0:00:32.57,0:00:37.30,Default,,0000,0000,0000,,mongolian. And mostly what I did was,\NI had this stream of auditory signals Dialogue: 0,0:00:37.30,0:00:43.12,Default,,0000,0000,0000,,that maybe came from the ASML audio, and\NI tried to match those to symbols that Dialogue: 0,0:00:43.12,0:00:46.39,Default,,0000,0000,0000,,were representing these, right, in the\Nbook. Dialogue: 0,0:00:47.47,0:00:52.00,Default,,0000,0000,0000,,And I kind of had this feeling that this\Nis incomplete. Dialogue: 0,0:00:52.00,0:00:53.84,Default,,0000,0000,0000,,So there is something missing there. Dialogue: 0,0:00:53.84,0:00:59.79,Default,,0000,0000,0000,,And while I was on the other hand,\Nstudying a lot about multimodal language Dialogue: 0,0:00:59.79,0:01:03.71,Default,,0000,0000,0000,,processing, which I how gestures influence\Nprocessing and stuff like that. Dialogue: 0,0:01:04.57,0:01:07.92,Default,,0000,0000,0000,,I came to the conclusion that, yeah, there\Nis something missing. Dialogue: 0,0:01:08.60,0:01:12.27,Default,,0000,0000,0000,,In our world today, we are all litterate\Nso we mostly think of languages as Dialogue: 0,0:01:12.27,0:01:16.48,Default,,0000,0000,0000,,these auditory signals, these mouth noises\Nand the symbols that represent these. Dialogue: 0,0:01:16.48,0:01:21.58,Default,,0000,0000,0000,,But there is so much more going on, in\Nface to face communication and, yeah, Dialogue: 0,0:01:21.58,0:01:25.28,Default,,0000,0000,0000,,I want to make this point clear, with a\Nvirtual experiment. Dialogue: 0,0:01:25.65,0:01:33.14,Default,,0000,0000,0000,,So, I want to invite you to first of all,\Nlisten to this audio excerpt, from an Dialogue: 0,0:01:33.14,0:01:38.48,Default,,0000,0000,0000,,"Easy Languages" video. And I give you the\Nsubtitles here, with the english Dialogue: 0,0:01:38.48,0:01:43.78,Default,,0000,0000,0000,,translation as well. So, basically, these\Nare auditory signals in Dutch, Dialogue: 0,0:01:43.78,0:01:47.20,Default,,0000,0000,0000,,and sequences of symbols\Nin Dutch and English. Dialogue: 0,0:01:47.20,0:01:51.47,Default,,0000,0000,0000,,And for the people learning Dutch, please\Njust ignore the English, just to make it Dialogue: 0,0:01:51.47,0:01:55.20,Default,,0000,0000,0000,,a little bit harder. And people who know\NDutch, please close your eyes, so that Dialogue: 0,0:01:55.20,0:01:59.70,Default,,0000,0000,0000,,you don't see it at all.\NSo, let's go. Dialogue: 0,0:02:40.56,0:02:46.42,Default,,0000,0000,0000,,So, when I was listening to this at first,\NI was - because I know some Dutch, Dialogue: 0,0:02:46.42,0:02:50.34,Default,,0000,0000,0000,,I was understanding quite a lot,\Nbut, kind of, not everything. Dialogue: 0,0:02:50.34,0:02:54.59,Default,,0000,0000,0000,,And then, I watched the video that goes\Nwith it, it was kind of a different experience. Dialogue: 0,0:02:54.90,0:03:00.90,Default,,0000,0000,0000,,And that's what we are going to do now.\NSo just watch the video, and if you can, Dialogue: 0,0:03:00.90,0:03:07.15,Default,,0000,0000,0000,,see how these two women, that are\Ninterviewed here, are interacting Dialogue: 0,0:03:07.15,0:03:10.17,Default,,0000,0000,0000,,with the interviewer, and\Nbetween each other. Dialogue: 0,0:03:50.93,0:03:54.01,Default,,0000,0000,0000,,So, I hoped this worked, and you felt\Na little bit different now. Dialogue: 0,0:03:54.01,0:03:57.89,Default,,0000,0000,0000,,And even for the people who don't know\NDutch, I hope you could kind of follow Dialogue: 0,0:03:57.89,0:04:03.06,Default,,0000,0000,0000,,what was going on. And even if you\Ndidn't, the point I want to make is that Dialogue: 0,0:04:03.06,0:04:06.29,Default,,0000,0000,0000,,messages are not only auditory,\Nthey are always also visual. Dialogue: 0,0:04:06.60,0:04:11.19,Default,,0000,0000,0000,,We have a lot of non-auditory\Narticulators, like 43 face muscles Dialogue: 0,0:04:11.19,0:04:15.92,Default,,0000,0000,0000,,for example, and then 2x 34 muscles\Nin the hands, and then even more in Dialogue: 0,0:04:15.92,0:04:20.89,Default,,0000,0000,0000,,the arms, in our torso.\NAnd the people in this video Dialogue: 0,0:04:20.89,0:04:24.78,Default,,0000,0000,0000,,really knew how to use these.\NSo for example we had a lot of Dialogue: 0,0:04:24.78,0:04:27.99,Default,,0000,0000,0000,,facial movement going on,\Nlike you see on the top, here. Dialogue: 0,0:04:27.99,0:04:32.19,Default,,0000,0000,0000,,See how she raise her eyebrows,\Nand then, you have this head tilting Dialogue: 0,0:04:32.19,0:04:35.19,Default,,0000,0000,0000,,at the end, that really put \Nan emphasis on what she's saying. Dialogue: 0,0:04:35.19,0:04:39.19,Default,,0000,0000,0000,,And then there is a lot of gaze switching\Nas well.That's right in the begining, Dialogue: 0,0:04:39.19,0:04:42.52,Default,,0000,0000,0000,,when she says \N(Dutch): Oh genoeg ! Heb je even ? Dialogue: 0,0:04:42.52,0:04:46.34,Default,,0000,0000,0000,,So, "Oh, there is so much that\NI want to see! Do you have some time?" Dialogue: 0,0:04:46.57,0:04:51.62,Default,,0000,0000,0000,,But, she doesn't really say "time", she\Nsays "Heb je even", "Do you have a little" Dialogue: 0,0:04:51.62,0:04:55.31,Default,,0000,0000,0000,,And for me, when I was only listening,\NI didn't quite get what she was saying, Dialogue: 0,0:04:55.31,0:04:58.42,Default,,0000,0000,0000,,but when I saw how she adresses\Nthe interviewer, I kind of got it, Dialogue: 0,0:04:58.42,0:04:59.42,Default,,0000,0000,0000,,afterwards. Dialogue: 0,0:05:00.57,0:05:05.92,Default,,0000,0000,0000,,So then there is of course manual gestures\Nlike "hoop op mijn list", Dialogue: 0,0:05:05.92,0:05:11.67,Default,,0000,0000,0000,,that's that one here, "hoop op mijn list".\NShe says "berglandschap", so that's Dialogue: 0,0:05:11.67,0:05:16.88,Default,,0000,0000,0000,,a mountain range, and then "lang geleden"\N"long time ago", right? Dialogue: 0,0:05:16.88,0:05:22.19,Default,,0000,0000,0000,,So there is a lot of messages that are\Nsupported with these manual gestures. Dialogue: 0,0:05:22.71,0:05:26.59,Default,,0000,0000,0000,,Then there is also stuff like this\Nnose scratching, where we don't even know Dialogue: 0,0:05:26.59,0:05:30.29,Default,,0000,0000,0000,,is there something to it, or is it just\Na nose scratching. Dialogue: 0,0:05:30.58,0:05:34.04,Default,,0000,0000,0000,,Does it carry some information?\NWe don't know. Dialogue: 0,0:05:35.16,0:05:37.81,Default,,0000,0000,0000,,And then, lastly also arm and torso\Nmovements. Dialogue: 0,0:05:37.81,0:05:41.14,Default,,0000,0000,0000,,And also if you watch at the top here,\Nyou have nodding. So you see how Dialogue: 0,0:05:41.14,0:05:45.61,Default,,0000,0000,0000,,these two kind of nod together, they\Nreally give us the impression of Dialogue: 0,0:05:45.61,0:05:51.09,Default,,0000,0000,0000,,how good friends they are, right.\NAnd then if you look at this bottom part Dialogue: 0,0:05:51.09,0:05:54.59,Default,,0000,0000,0000,,here, that's my favorite part of the\Nvideo. You really have this complex Dialogue: 0,0:05:54.59,0:06:00.29,Default,,0000,0000,0000,,orchestration of different gestures,\Nand they are turn-taking. Dialogue: 0,0:06:00.55,0:06:07.07,Default,,0000,0000,0000,,So, the one on the right says something,\Nand the one on the left answers that Dialogue: 0,0:06:07.07,0:06:12.96,Default,,0000,0000,0000,,perfectly, and then you have gestures,\Nand then the, putting their hair back, Dialogue: 0,0:06:12.96,0:06:18.47,Default,,0000,0000,0000,,right, so there is so much going on\Nbetween them, and it really gives more Dialogue: 0,0:06:18.47,0:06:21.99,Default,,0000,0000,0000,,than just the auditory message, right. Dialogue: 0,0:06:23.15,0:06:27.49,Default,,0000,0000,0000,,So, note that there is something that\Nour brain has to achieve here. Dialogue: 0,0:06:27.49,0:06:31.49,Default,,0000,0000,0000,,Mainly two things : so, it has to\Nsegregate all of the stuff that is not Dialogue: 0,0:06:31.49,0:06:34.33,Default,,0000,0000,0000,,important for the message.\NThat's the segregation problem. Dialogue: 0,0:06:34.50,0:06:37.99,Default,,0000,0000,0000,,From the important stuff, and then,\Ntake all the important stuff, all Dialogue: 0,0:06:37.99,0:06:41.89,Default,,0000,0000,0000,,the auditory and visuals information and\Nput it together into a coherent message. Dialogue: 0,0:06:41.95,0:06:45.65,Default,,0000,0000,0000,,That's our binding problem.\NAnd all of this, note, all of this is Dialogue: 0,0:06:45.65,0:06:49.26,Default,,0000,0000,0000,,under a really tight time constraint,\Nwhen you're turn taking, when you're Dialogue: 0,0:06:49.26,0:06:51.65,Default,,0000,0000,0000,,having a conversation.\NAnd if you say something and Dialogue: 0,0:06:51.65,0:06:54.61,Default,,0000,0000,0000,,the other person say something,\Nand there is not that much time Dialogue: 0,0:06:54.61,0:06:57.42,Default,,0000,0000,0000,,between turns. And if you need\Nmore time, then that also has Dialogue: 0,0:06:57.42,0:07:01.95,Default,,0000,0000,0000,,a meaning, right ? If you take time, then\Nthat means that you're hesitating Dialogue: 0,0:07:01.95,0:07:05.15,Default,,0000,0000,0000,,to answer, maybe there is something\Ngoing on with you emotionally... Dialogue: 0,0:07:05.15,0:07:10.21,Default,,0000,0000,0000,,So you don't want to have that as well.\NSo, yeah, so basically, this is really Dialogue: 0,0:07:10.21,0:07:12.71,Default,,0000,0000,0000,,a huge computational problem\Nfor your brain. Dialogue: 0,0:07:13.84,0:07:18.01,Default,,0000,0000,0000,,And well, how did your brain do?\NDid you feel the video was more difficult Dialogue: 0,0:07:18.01,0:07:21.66,Default,,0000,0000,0000,,than the audio ? Did you understand more,\Nor did you understand less? Dialogue: 0,0:07:21.81,0:07:25.78,Default,,0000,0000,0000,,Did you feel more in the scene, maybe?\NCatching more informations between the lines? Dialogue: 0,0:07:26.65,0:07:31.50,Default,,0000,0000,0000,,And well, for me, at least as you might\Nguess, for me it was way easier Dialogue: 0,0:07:31.50,0:07:34.94,Default,,0000,0000,0000,,to follow with the video to interpret\Nthese gestures. And this is kind of Dialogue: 0,0:07:34.94,0:07:40.70,Default,,0000,0000,0000,,a paradox. So, how come that processing\Nmore signals simultaneously is easier Dialogue: 0,0:07:40.70,0:07:45.93,Default,,0000,0000,0000,,that processing speech alone?\NAnd this also was shown Dialogue: 0,0:07:45.93,0:07:49.23,Default,,0000,0000,0000,,in the litterature, so people have made\Nexperience with this. Dialogue: 0,0:07:49.73,0:07:54.57,Default,,0000,0000,0000,,And this is really a surprising\Nfacilitation. For example, there are Dialogue: 0,0:07:54.57,0:07:57.13,Default,,0000,0000,0000,,lot of studies, I'll just give you\None example. Dialogue: 0,0:07:57.42,0:08:01.12,Default,,0000,0000,0000,,So in this study they showed people\Na "prime", so this was some video Dialogue: 0,0:08:01.12,0:08:05.36,Default,,0000,0000,0000,,of an action that somebody did, and then\Nthey showed the people different videos. Dialogue: 0,0:08:05.80,0:08:10.35,Default,,0000,0000,0000,,And the videos were either completely\Ncongruent, so what was said was the same Dialogue: 0,0:08:10.35,0:08:14.35,Default,,0000,0000,0000,,as the gesture, and was the same as\Nthis prime. So in that case it would be Dialogue: 0,0:08:14.35,0:08:18.61,Default,,0000,0000,0000,,"chop" and doing the chopping gesture.\NAnd then there were different conditions Dialogue: 0,0:08:18.61,0:08:26.41,Default,,0000,0000,0000,,where either the speech was congruent,\Nincongruent, and the gesture was congruent. Dialogue: 0,0:08:26.61,0:08:29.84,Default,,0000,0000,0000,,Or the speech was incongruent and\Nthe gesture was congruent. Dialogue: 0,0:08:29.95,0:08:34.36,Default,,0000,0000,0000,,And then they had also weakly congruent\Nstuff, like, this for "chopping", Dialogue: 0,0:08:34.36,0:08:37.75,Default,,0000,0000,0000,,but this is actually cutting so this is\Nonly weakly incongruent. Dialogue: 0,0:08:37.75,0:08:41.52,Default,,0000,0000,0000,,And then this twisting, which is\Nstrongly incongruent. Dialogue: 0,0:08:42.48,0:08:47.26,Default,,0000,0000,0000,,And then people had to press a button\Nfor "yes" if either the speech or Dialogue: 0,0:08:47.26,0:08:52.13,Default,,0000,0000,0000,,the gesture were related to the prime,\Nand no if neither speech nor gesture Dialogue: 0,0:08:52.13,0:08:55.38,Default,,0000,0000,0000,,was related to the prime.\NAnd what the people found out was that Dialogue: 0,0:08:55.38,0:08:59.05,Default,,0000,0000,0000,,there were differences in response times,\Nand also in the proportion of errors Dialogue: 0,0:08:59.05,0:09:02.40,Default,,0000,0000,0000,,that people did, as soon as soon as \Nthere were something incongruent. Dialogue: 0,0:09:02.40,0:09:07.72,Default,,0000,0000,0000,,And from that the authors come to\Nthe conclusion that really, speech and Dialogue: 0,0:09:07.72,0:09:11.91,Default,,0000,0000,0000,,gestures are two sides of the\Nsame coin, they mutually interact Dialogue: 0,0:09:11.91,0:09:16.08,Default,,0000,0000,0000,,to enhance comprehension.\NAnd now the big question is, of course, Dialogue: 0,0:09:16.08,0:09:19.32,Default,,0000,0000,0000,,how does our brain achieve this surprising\Nfacilitation? Dialogue: 0,0:09:21.98,0:09:25.80,Default,,0000,0000,0000,,And we can look back at turn-taking,\Nto maybe get some clues here. Dialogue: 0,0:09:25.80,0:09:32.05,Default,,0000,0000,0000,,So on average a turn-take takes only\Nabout 0 to 200 miliseconds, which is Dialogue: 0,0:09:32.05,0:09:38.07,Default,,0000,0000,0000,,a fifth of a second. You can see in this\Nvideo how fast she is responding, Dialogue: 0,0:09:38.07,0:09:43.10,Default,,0000,0000,0000,,right now, after this, like, this is\Nan instant, right? Dialogue: 0,0:09:43.86,0:09:47.95,Default,,0000,0000,0000,,And this is quite extraordinary, because\Nproducing a single word actually takes Dialogue: 0,0:09:47.95,0:09:49.37,Default,,0000,0000,0000,,about 600 miliseconds. Dialogue: 0,0:09:49.69,0:09:54.87,Default,,0000,0000,0000,,So if I just prompt you to say a word,\Nyou would take 600 miliseconds to say it. Dialogue: 0,0:09:55.85,0:10:00.10,Default,,0000,0000,0000,,So there's something going on, it seems\Nlike we are predicting already what we are Dialogue: 0,0:10:00.10,0:10:04.15,Default,,0000,0000,0000,,going to say before the turn of the other\Nperson is finished, and we already prepare Dialogue: 0,0:10:04.15,0:10:05.36,Default,,0000,0000,0000,,our turn. Dialogue: 0,0:10:05.36,0:10:09.56,Default,,0000,0000,0000,,So there is something that is going on,\Nthat has to do with prediction. Dialogue: 0,0:10:10.69,0:10:14.99,Default,,0000,0000,0000,,Most language use in conversation\Nhas to be based on prediction somehow. Dialogue: 0,0:10:14.99,0:10:18.31,Default,,0000,0000,0000,,And this is quite nice, because prediction\Nis anyways the current hype Dialogue: 0,0:10:18.31,0:10:21.81,Default,,0000,0000,0000,,in neuroscience nowadays, and it's\Nbasically a good candidate for Dialogue: 0,0:10:21.81,0:10:23.98,Default,,0000,0000,0000,,the overarching function of the brain. Dialogue: 0,0:10:25.30,0:10:30.63,Default,,0000,0000,0000,,And many people think that what we are\Ndoing in our daily lives is basically Dialogue: 0,0:10:30.63,0:10:34.38,Default,,0000,0000,0000,,constantly computing and updating\Nprobability distributions. Dialogue: 0,0:10:35.03,0:10:38.53,Default,,0000,0000,0000,,And this applies both to action,\Nto perception, and also to language.

Dialogue: 0,0:11:48.51,0:11:53.94,Default,,0000,0000,0000,,So, in this way gestures add context to\Npredictions and help this process of Dialogue: 0,0:11:53.94,0:11:56.66,Default,,0000,0000,0000,,predicting, and that also helps the\Ncomprehension.

Dialogue: 0,0:12:42.77,0:12:46.50,Default,,0000,0000,0000,,So this would be : "He spread the warm\Nbread with socks."

And this weird\Nfeeling, if we would measure you with Dialogue: 0,0:12:56.88,0:13:03.76,Default,,0000,0000,0000,,an EEG, would constitute this reaction\Nhere, that's a so-called N400.

It is already on Dialogue: 0,0:14:36.27,0:14:43.74,Default,,0000,0000,0000,,the archive. And I want to use this to\Nillustrate to you how we might research Dialogue: 0,0:14:43.74,0:14:49.47,Default,,0000,0000,0000,,naturalistic language comprehension.\NSo the general planners get some Dialogue: 0,0:14:49.47,0:14:54.41,Default,,0000,0000,0000,,per-word measures - so these would be\Nthese ones here. So for each word, Dialogue: 0,0:14:54.41,0:14:59.87,Default,,0000,0000,0000,,there is some value attached.\NAnd then we can use these as regressors Dialogue: 0,0:14:59.87,0:15:04.74,Default,,0000,0000,0000,,in the big linear regression model.\NSo, using fancy statistics, and with that Dialogue: 0,0:15:04.74,0:15:12.78,Default,,0000,0000,0000,,we're basically asking our data "how well\Nare you predicted by these regressors?" Dialogue: 0,0:15:14.40,0:15:19.28,Default,,0000,0000,0000,,And for example, this one here is\Nsurprise and this is closely related Dialogue: 0,0:15:19.28,0:15:25.16,Default,,0000,0000,0000,,to predictions or prediction errors.\NSo this is the negative log probability Dialogue: 0,0:15:25.16,0:15:28.63,Default,,0000,0000,0000,,of a word, given all of the words\Nthat come before it. Dialogue: 0,0:15:28.63,0:15:32.96,Default,,0000,0000,0000,,So, this is the contexte, basically,\Nand this is some word, "w". Dialogue: 0,0:15:34.11,0:15:37.41,Default,,0000,0000,0000,,So this is basically telling you how\Nunpredictable is a given word. Dialogue: 0,0:15:38.56,0:15:42.68,Default,,0000,0000,0000,,And this measure is base on computational\Nlanguage models, so for example, Dialogue: 0,0:15:42.68,0:15:47.61,Default,,0000,0000,0000,,they would take the whole corpus of\Na language, and then, see which words Dialogue: 0,0:15:47.61,0:15:54.08,Default,,0000,0000,0000,,occurs after each other, and thereby get\Nto this value of how unpredictable it is. Dialogue: 0,0:15:55.96,0:16:00.78,Default,,0000,0000,0000,,And then, they have another thing here.\NThey use the fundamental frequency of each Dialogue: 0,0:16:00.78,0:16:05.53,Default,,0000,0000,0000,,word as a pitch indicator, to control\Nfor prosody, which is also pretty cool. Dialogue: 0,0:16:06.49,0:16:10.66,Default,,0000,0000,0000,,So they let loose their linear\Nregression models, with these predictors, Dialogue: 0,0:16:10.66,0:16:17.56,Default,,0000,0000,0000,,so they have a surprisal value for each\Nword, for example, a prosody, ready for Dialogue: 0,0:16:17.56,0:16:21.68,Default,,0000,0000,0000,,each word, then they indicate where\Nthere are meaningful gestures happening, Dialogue: 0,0:16:21.68,0:16:25.41,Default,,0000,0000,0000,,and, yeah, also, mouth movements. Dialogue: 0,0:16:26.94,0:16:30.41,Default,,0000,0000,0000,,And, what came out of this, one finding\Nthat might be interesting for us, Dialogue: 0,0:16:30.41,0:16:36.91,Default,,0000,0000,0000,,now, is that for meaningful gestures,\Nthe N400 is less negative. Dialogue: 0,0:16:37.81,0:16:42.81,Default,,0000,0000,0000,,So you can also see this here : for\Nmeaningful gesture, this blue line, Dialogue: 0,0:16:42.81,0:16:47.82,Default,,0000,0000,0000,,you see that it is a lot less negative\Nthan the red line where the gestures are Dialogue: 0,0:16:47.82,0:16:53.22,Default,,0000,0000,0000,,absent. And then there's also, that's why\NI told you about surprisal, an interesting Dialogue: 0,0:16:53.22,0:16:57.59,Default,,0000,0000,0000,,interaction between gestures and\Nsurprisal. So, the higher the surprisal, Dialogue: 0,0:16:57.59,0:17:03.07,Default,,0000,0000,0000,,the less unexpected a word, the stronger\Nthis facilitating effect of gestures is. Dialogue: 0,0:17:04.05,0:17:09.72,Default,,0000,0000,0000,,Which is also really interesting.\NThen there's, this is a similar study, Dialogue: 0,0:17:11.61,0:17:14.87,Default,,0000,0000,0000,,that I actually got the chance to work on,\Nwith a colleague. Dialogue: 0,0:17:16.55,0:17:21.45,Default,,0000,0000,0000,,So what we did here, we had a measure of\Nentropy. This measures basically the Dialogue: 0,0:17:21.52,0:17:25.60,Default,,0000,0000,0000,,uncertainty about the next word.\NSo if you think back to the example Dialogue: 0,0:17:25.60,0:17:30.97,Default,,0000,0000,0000,,we had before, where I was telling\Nyou "I would like to", and then something, Dialogue: 0,0:17:30.97,0:17:34.86,Default,,0000,0000,0000,,but without context, that would be really\Nhigh entropy, really high uncertainty : Dialogue: 0,0:17:34.86,0:17:39.53,Default,,0000,0000,0000,,you don't know what's coming next. Right?\NThen we also had surprisal, we had word Dialogue: 0,0:17:39.53,0:17:43.63,Default,,0000,0000,0000,,frequency, how often the word came up.\NAnd IVC is a measure of, Dialogue: 0,0:17:43.63,0:17:49.89,Default,,0000,0000,0000,,it's an abbreviation for "instantaneous\Nvisual change", so, how much the actor Dialogue: 0,0:17:49.89,0:17:56.20,Default,,0000,0000,0000,,moved while we were showing this to\Nthe people. And then speech envelope, Dialogue: 0,0:17:56.20,0:18:00.77,Default,,0000,0000,0000,,this is basically a measure of the level\Nof the sound. Dialogue: 0,0:18:02.66,0:18:08.80,Default,,0000,0000,0000,,And what we found is - and this\Nby the way was an FRMI experiment, Dialogue: 0,0:18:08.80,0:18:12.61,Default,,0000,0000,0000,,so we can look at wich regions are active\Nduring some condition. Dialogue: 0,0:18:13.43,0:18:17.99,Default,,0000,0000,0000,,And for words where the surprisal was\Nreally high, there were these regions Dialogue: 0,0:18:17.99,0:18:20.99,Default,,0000,0000,0000,,in red active, and for words where\Nentropy was really high, Dialogue: 0,0:18:20.99,0:18:25.51,Default,,0000,0000,0000,,these regions in blue. And now if\Nwe look at interactions with gestures Dialogue: 0,0:18:25.51,0:18:31.81,Default,,0000,0000,0000,,for the entropy condition, we can see that\Nwhen there were gestures present, we had Dialogue: 0,0:18:31.81,0:18:37.79,Default,,0000,0000,0000,,really specific activations compared\Nto when there were no gestures present, Dialogue: 0,0:18:37.79,0:18:41.28,Default,,0000,0000,0000,,in situations where there is high\Nentropy, so high uncertainty. Dialogue: 0,0:18:42.59,0:18:50.07,Default,,0000,0000,0000,,So with these tools we try to get into\Nthe processes that underlie prediction Dialogue: 0,0:18:50.07,0:18:55.90,Default,,0000,0000,0000,,in language.\NSo let's take a step back, and have a look Dialogue: 0,0:18:55.90,0:19:00.07,Default,,0000,0000,0000,,at kind of a more global\Nevolutionnary perspective. Dialogue: 0,0:19:01.67,0:19:06.39,Default,,0000,0000,0000,,We know from primate research that gesture\Nand gaze are crucial for communication. Dialogue: 0,0:19:06.77,0:19:10.03,Default,,0000,0000,0000,,You can see it in this video : this ape\Nright here does this gesture, Dialogue: 0,0:19:10.46,0:19:14.88,Default,,0000,0000,0000,,and this signals to its mother\Nto pick her up. Right? Dialogue: 0,0:19:15.48,0:19:21.97,Default,,0000,0000,0000,,So these are bonobos, and you can see\Nright now, this "pick me up" gesture. Dialogue: 0,0:19:23.52,0:19:29.34,Default,,0000,0000,0000,,And Federico Rossano, from the Max Planck\NInstitute for Evolutionnary Institute, Dialogue: 0,0:19:30.19,0:19:35.94,Default,,0000,0000,0000,,could show that this gesture get more\Nand more ritualized, to the point where Dialogue: 0,0:19:35.94,0:19:45.99,Default,,0000,0000,0000,,it becomes only a small wrist bend with\Nthe arm and one gaze, to instantiate Dialogue: 0,0:19:45.99,0:19:50.19,Default,,0000,0000,0000,,this carry behavior. Right?\NSo you see that there is also kind of Dialogue: 0,0:19:50.19,0:19:56.50,Default,,0000,0000,0000,,a prediction involved : the mother has\Nto predict what the child is wanting Dialogue: 0,0:19:56.50,0:20:00.09,Default,,0000,0000,0000,,to do, right? \NGoing from this, to only this. Dialogue: 0,0:20:01.17,0:20:06.99,Default,,0000,0000,0000,,Then, building on this, there are some\Nauthors that propose that speech and Dialogue: 0,0:20:06.99,0:20:11.69,Default,,0000,0000,0000,,gesture have a common origin.\NAnd the idea here is that, through Dialogue: 0,0:20:11.69,0:20:15.20,Default,,0000,0000,0000,,these ritualized gestures that\Nwe've just seen in those bonobos, Dialogue: 0,0:20:15.20,0:20:18.65,Default,,0000,0000,0000,,after a time there will be a proto\Nsign language evolving.

Dialogue: 0,0:20:34.38,0:20:40.47,Default,,0000,0000,0000,,And another point, here,\Nor an observation : those of you who have Dialogue: 0,0:20:40.47,0:20:44.14,Default,,0000,0000,0000,,tried sign language, it kind of feel\Nsurprinsingly natural, right? Dialogue: 0,0:20:44.14,0:20:50.72,Default,,0000,0000,0000,,So, if speech is the true communication\Nmedium for humans, why is it Dialogue: 0,0:20:50.72,0:20:56.29,Default,,0000,0000,0000,,thet sign language feels so real,\Nso natural, right? Dialogue: 0,0:20:58.20,0:21:03.44,Default,,0000,0000,0000,,And then another point that goes into this\Ntheory is that voluntary hand movements Dialogue: 0,0:21:03.44,0:21:07.55,Default,,0000,0000,0000,,came before voluntary breathing. And you\Nneed voluntary breathing to articulate Dialogue: 0,0:21:07.55,0:21:08.82,Default,,0000,0000,0000,,yourself, right? Dialogue: 0,0:21:09.68,0:21:13.90,Default,,0000,0000,0000,,So, also, just as complementary to speech, Dialogue: 0,0:21:13.90,0:21:18.06,Default,,0000,0000,0000,,you can more easily show spatial\Nrelations between things. Dialogue: 0,0:21:18.97,0:21:22.62,Default,,0000,0000,0000,,And then, if you look at child development\Nthe same pattern : gesture develop Dialogue: 0,0:21:22.62,0:21:29.88,Default,,0000,0000,0000,,before speech, and pre-speech turn-taking\Nis faster than later.

Dialogue: 0,0:43:06.12,0:43:08.91,Default,,0000,0000,0000,,And what they found is that\Nthe language network Dialogue: 0,0:43:08.91,0:43:15.69,Default,,0000,0000,0000,,was less active than for monolinguals. Dialogue: 0,0:43:16.35,0:43:19.79,Default,,0000,0000,0000,,So if you listen to something\Nthere's some areas Dialogue: 0,0:43:19.79,0:43:22.08,Default,,0000,0000,0000,,on the left side of your brain\Nthat light up : Dialogue: 0,0:43:22.08,0:43:26.81,Default,,0000,0000,0000,,you have some typical areas,\Nlike Broca's area, Wernicke's area, Dialogue: 0,0:43:27.01,0:43:28.58,Default,,0000,0000,0000,,and some other ones. Dialogue: 0,0:43:29.00,0:43:34.16,Default,,0000,0000,0000,,And they found that, for polyglots\Nthis "lighting up" is less, Dialogue: 0,0:43:34.16,0:43:38.82,Default,,0000,0000,0000,,and the interpretation was that\Nthe polyglots' language network, Dialogue: 0,0:43:38.82,0:43:42.91,Default,,0000,0000,0000,,through extensive practice, has become\Nmore and more efficient Dialogue: 0,0:43:42.91,0:43:47.58,Default,,0000,0000,0000,,at dealing with language.\NAnd therefore it needs less activation. Dialogue: 0,0:43:47.98,0:43:53.22,Default,,0000,0000,0000,,So this is one thing that\Nyou observe quite often, Dialogue: 0,0:43:59.29,0:44:01.91,Default,,0000,0000,0000,,when there's some process that\Nyou get really good at, Dialogue: 0,0:44:02.67,0:44:05.100,Default,,0000,0000,0000,,in your brain the activity\Nthat you see goes down, Dialogue: 0,0:44:05.100,0:44:08.33,Default,,0000,0000,0000,,because the network gets more efficient. Dialogue: 0,0:44:08.67,0:44:11.35,Default,,0000,0000,0000,,So that's why this paper was aptly titled Dialogue: 0,0:44:11.35,0:44:14.96,Default,,0000,0000,0000,,"The Small And Efficient Network\NOf Polyglots And Hyperpolyglots". Dialogue: 0,0:44:15.63,0:44:18.04,Default,,0000,0000,0000,,And they, you can also look this up as well, Dialogue: 0,0:44:18.56,0:44:22.38,Default,,0000,0000,0000,,they also made them listen to\Ndifferent languages, Dialogue: 0,0:44:23.07,0:44:27.53,Default,,0000,0000,0000,,and there, the better known\Nthe foreign language was Dialogue: 0,0:44:28.10,0:44:32.39,Default,,0000,0000,0000,,so the first experiment was completed\Nin english, their mother tongue, Dialogue: 0,0:44:32.68,0:44:37.11,Default,,0000,0000,0000,,and then the second experiment they used\Ntheir target languages like, Dialogue: 0,0:44:37.11,0:44:39.85,Default,,0000,0000,0000,,the second best language, third best\Nlanguage and so on. Dialogue: 0,0:44:40.57,0:44:44.81,Default,,0000,0000,0000,,And there, the lesser known a language,\Nthe less active the language network, Dialogue: 0,0:44:45.17,0:44:49.04,Default,,0000,0000,0000,,and the better known, the more active.\NSo you have kind of the opposite effect. Dialogue: 0,0:44:49.29,0:44:52.47,Default,,0000,0000,0000,,And they interpreted this as reflecting\Nthat the more you know Dialogue: 0,0:44:52.47,0:44:54.64,Default,,0000,0000,0000,,in a target language,\Nin a foreign language, Dialogue: 0,0:44:54.77,0:45:00.34,Default,,0000,0000,0000,,the more of the language network\Ngets recruited, the more context you have.
