WEBVTT FILE 1 00:00:00.000 --> 00:00:00.060 [Music] 2 00:00:00.060 --> 00:00:02.040 you're about to take a complete practice 3 00:00:02.040 --> 00:00:04.860 test for the TOEFL IBT listening section 4 00:00:04.860 --> 00:00:07.919 my name is Josh I'm from TST prep and 5 00:00:07.919 --> 00:00:09.179 there are a couple of differences 6 00:00:09.179 --> 00:00:12.119 between this test and the actual TOEFL 7 00:00:12.119 --> 00:00:15.179 so the first difference is that on test 8 00:00:15.179 --> 00:00:18.480 day you're in control of your time so if 9 00:00:18.480 --> 00:00:20.279 you want to just take five seconds to 10 00:00:20.279 --> 00:00:22.439 answer a question or you want to take a 11 00:00:22.439 --> 00:00:24.539 minute to answer a question it's up to 12 00:00:24.539 --> 00:00:27.359 you but for this practice on YouTube 13 00:00:27.359 --> 00:00:29.760 each question has the same length of 14 00:00:29.760 --> 00:00:32.220 time for you to complete so keep that in 15 00:00:32.220 --> 00:00:34.739 mind the second thing is that there is a 16 00:00:34.739 --> 00:00:37.380 link in the description below to a PDF 17 00:00:37.380 --> 00:00:40.200 with explanations for all of the answers 18 00:00:40.200 --> 00:00:42.600 so if you need more explanation for why 19 00:00:42.600 --> 00:00:44.640 something is correct or incorrect 20 00:00:44.640 --> 00:00:46.920 definitely check that out also you'll 21 00:00:46.920 --> 00:00:48.659 see all the answers in the description 22 00:00:48.659 --> 00:00:51.320 so again answers are in the description 23 00:00:51.320 --> 00:00:53.940 and if you need more help with courses 24 00:00:53.940 --> 00:00:56.520 classes more practice questions check 25 00:00:56.520 --> 00:00:59.820 out tscprep.com use coupon code TSC prep 26 00:00:59.820 -->

00:01:07.680 --> 00:01:09.799 end 30 00:01:10.740 --> 00:01:13.740 foreign 31 00:01:19.700 --> 00:01:23.340 to a conversation between a student and 32 00:01:23.340 --> 00:01:25.939 a professor 33 00:01:26.040 --> 00:01:28.319 good morning Professor Jacobs 34 00:01:28.319 --> 00:01:29.340 again 35 00:01:29.340 --> 00:01:31.319 hi Jane my weekend was great very 36 00:01:31.319 --> 00:01:35.100 relaxing how about yours I had a blast I 37 00:01:35.100 --> 00:01:36.900 went to an exhibition at a gallery in 38 00:01:36.900 --> 00:01:38.578 the city and one of the artists was 39 00:01:38.578 --> 00:01:41.700 there I got to meet him unfortunately I 40 00:01:41.700 --> 00:01:43.920 don't remember his name but he does drip 41 00:01:43.920 --> 00:01:45.959 art just like Jackson Pollock it was 42 00:01:45.959 --> 00:01:47.579 really cool and inspiring to meet 43 00:01:47.579 --> 00:01:50.040 someone who creates art for a living wow 44 00:01:50.040 --> 00:01:52.079 what an exciting weekend it sounds like 45 00:01:52.079 --> 00:01:53.460 you really have found some inspiration 46 00:01:53.460 --> 00:01:55.500 for your dripart project how's that 47 00:01:55.500 --> 00:01:56.640 coming along 48 00:01:56.640 --> 00:01:59.220 well that's kind of what I wanted to 49 00:01:59.220 --> 00:02:01.380 talk to you about I think drip art is 50 00:02:01.380 --> 00:02:03.299 really unique and interesting but I'm 51 00:02:03.299 --> 00:02:05.759 having trouble with the assignment what 52 00:02:05.759 --> 00:02:07.500 seems to be the problem I started 53 00:02:07.500 --> 00:02:09.119 working on the project right after going 54 00:02:09.119 --> 00:02:11.280 to the exhibit but I feel like I'm stuck 55 00:02:11.280 --> 00:02:12.840 and I'm worried I won't be able to 56 00:02:12.840 --> 00:02:14.220 create a piece that I'm comfortable 57 00:02:14.220 --> 00:02:15.900 handing in 58 00:02:15.900 --> 00:02:17.879 how so are you confused about the 59 00:02:17.879 --> 00:02:18.959 assignment 60 00:02:18.959 --> 00:02:21.360 I understand the assignment well but you 61 00:02:21.360 --> 00:02:22.860 know how you always tell us to express 62 00:02:22.860 --> 00:02:25.200 ourselves in our art that's why I feel 63 00:02:25.200 --> 00:02:27.599 frustrated with this project I feel like 64 00:02:27.599 --> 00:02:29.400 I'm forcing myself to create something 65 00:02:29.400 --> 00:02:32.160 and it just feels fake what would you do 66 00:02:32.160 --> 00:02:33.959 if you were in my shoes 67 00:02:33.959 --> 00:02:36.300 I completely understand your concern but 68 00:02:36.300 --> 00:02:38.639 that's the whole point of my class I 69 00:02:38.639 --> 00:02:40.260 want you to get out of your comfort zone 70 00:02:40.260 --> 00:02:43.200 let go and try something new 71 00:02:43.200 --> 00:02:45.900 okay I'll give it another shot today and 72 00:02:45.900 --> 00:02:47.280 I'll see if I can push past the feeling 73 00:02:47.280 --> 00:02:50.099 of being stuck that's a good idea and if 74 00:02:50.099 --> 00:02:52.080 you're still feeling uneasy I'm having a 75 00:02:52.080 --> 00:02:53.819 workshop this Saturday and you can join 76 00:02:53.819 --> 00:02:55.739 it if you like you can see some examples 77 00:02:55.739 --> 00:02:57.900 of drip art and watch the actual process 78 00:02:57.900 --> 00:03:00.780 that may be really helpful for you if 79 00:03:00.780 --> 00:03:02.519 you stay for a little while afterward we 80 00:03:02.519 --> 00:03:04.080 can discuss any further questions you 81 00:03:04.080 --> 00:03:04.980 may have 82 00:03:04.980 --> 00:03:07.800 that sounds great thank you so much I 83 00:03:07.800 --> 00:03:09.540 would love to attend the workshop I 84 00:03:09.540 --> 00:03:10.980 think that it's just what I need to help 85 00:03:10.980 --> 00:03:13.080 me finish this project you're welcome 86 00:03:13.080 --> 00:03:15.599 I'm glad you stopped by I'd rather you 87 00:03:15.599 --> 00:03:18.180 be confused and ask questions than say 88 00:03:18.180 --> 00:03:19.440 nothing and struggle with the project 89 00:03:19.440 --> 00:03:22.699 I'll see you on Saturday 90 00:03:23.400 --> 00:03:26.459 now answer the questions 91 00:03:26.459 --> 00:03:27.659 one 92 00:03:27.659 --> 00:03:30.120 why does the student want to talk to the 93 00:03:30.120 --> 00:03:32.599 professor 94 00:04:00.900 --> 00:04:02.040 two 95 00:04:02.040 --> 00:04:04.440 what does the student mean when she says 96 00:04:04.440 --> 00:04:08.180 the assignment feels fake 97 00:04:38.339 --> 00:04:39.419 three 98 00:04:39.419 --> 00:04:42.419 listen again to part of the passage why 99 00:04:42.419 --> 00:04:45.839 does the professor say this 100 00:04:45.839 --> 00:04:48.120 I completely understand your concern but 101 00:04:48.120 --> 00:04:50.460 that's the whole point of my class I 102 00:04:50.460 --> 00:04:51.960 want you to get out of your comfort zone 103 00:04:51.960 --> 00:04:56.120 let go and try something new 104 00:05:26.580 --> 00:05:27.600 four 105 00:05:27.600 --> 00:05:30.000 what suggestions does the professor make 106 00:05:30.000 --> 00:05:34.400 to the student select two 107 00:06:04.259 --> 00:06:05.460 five 108 00:06:05.460 --> 00:06:07.560 why does the professor suggest this 109 00:06:07.560 --> 00:06:11.240 student attend his Workshop 110 00:06:44.880 --> 00:06:47.880 now listen to part of a talk in an 111 00:06:47.880 --> 00:06:50.600 economics class 112 00:06:51.720 --> 00:06:53.699 today we're going to be discussing 113 00:06:53.699 --> 00:06:57.240 public goods so basically lots of 114 00:06:57.240 --> 00:06:59.520 individuals and businesses create new 115 00:06:59.520 --> 00:07:02.279 ideas and products every day and most 116 00:07:02.279 --> 00:07:03.779 expect to get some money from their 117 00:07:03.779 --> 00:07:06.240 Creations but what happens when you make 118 00:07:06.240 --> 00:07:08.100 something that has such a tremendous 119 00:07:08.100 --> 00:07:10.380 benefit to society that you can't expect 120 00:07:10.380 --> 00:07:13.440 to receive any money in return this kind 121 00:07:13.440 --> 00:07:16.319 of good is a public good can anyone 122 00:07:16.319 --> 00:07:18.660 think of examples of a public good 123 00:07:18.660 --> 00:07:21.720 well I'm not so sure but maybe some of 124 00:07:21.720 --> 00:07:23.699 the TV channels on basic cable I mean 125 00:07:23.699 --> 00:07:26.099 anyone with a TV and an antenna can get 126 00:07:26.099 --> 00:07:27.960 some channels to watch 127 00:07:27.960 --> 00:07:30.479 yes I didn't think of that before but 128 00:07:30.479 --> 00:07:32.759 you're right Sam basic cable channels 129 00:07:32.759 --> 00:07:35.400 are a public good another example might 130 00:07:35.400 --> 00:07:37.259 be a country's National Defense or 131 00:07:37.259 --> 00:07:40.020 military these exist purely to benefit 132 00:07:40.020 --> 00:07:41.280 the people 133 00:07:41.280 --> 00:07:43.440 Professor is there any way to kind of 134 00:07:43.440 --> 00:07:45.840 Judge whether a product is a public or 135 00:07:45.840 --> 00:07:48.060 private good I mean like those TV 136 00:07:48.060 --> 00:07:49.919 channels they might be free but you 137 00:07:49.919 --> 00:07:52.979 still need to buy a TV so I guess I'm 138 00:07:52.979 --> 00:07:55.199 just not sure how you can tell if 139 00:07:55.199 --> 00:07:58.500 something is a public good yes this idea 140 00:07:58.500 --> 00:08:01.139 can be a bit confusing I guess it's best 141 00:08:01.139 --> 00:08:03.840 to contrast it with a private good say a 142 00:08:03.840 --> 00:08:06.240 piece of pizza a piece of pizza can be 143 00:08:06.240 --> 00:08:08.699 bought and sold pretty easily and one of 144 00:08:08.699 --> 00:08:10.860 the reasons why is because it's so easy 145 00:08:10.860 --> 00:08:13.380 to separate I suppose one of the most 146 00:08:13.380 --> 00:08:15.660 defining characteristics of public goods 147 00:08:15.660 --> 00:08:17.759 is that they are almost impossible to 148 00:08:17.759 --> 00:08:20.400 separate TV Airways and the National 149 00:08:20.400 --> 00:08:22.740 Defense System are not things you can 150 00:08:22.740 --> 00:08:25.199 really break down into pieces it's the 151 00:08:25.199 --> 00:08:27.780 same with public Wi-Fi many cities are 152 00:08:27.780 --> 00:08:30.000 now offering free Wi-Fi to Residents 153 00:08:30.000 --> 00:08:33.360 Wi-Fi only exists in the air you can't 154 00:08:33.360 --> 00:08:36.260 hold Wi-Fi and separate it into pieces 155 00:08:36.260 --> 00:08:39.899 okay Professor I think I get it now but 156 00:08:39.899 --> 00:08:42.140 in the book they mentioned that terms 157 00:08:42.140 --> 00:08:44.820 non-excludable and non-rival risks when 158 00:08:44.820 --> 00:08:46.980 trying to explain public goods and I 159 00:08:46.980 --> 00:08:49.920 didn't really get it great I was just 160 00:08:49.920 --> 00:08:52.500 going to get to that so besides being 161 00:08:52.500 --> 00:08:54.958 hard to separate economists usually 162 00:08:54.958 --> 00:08:57.179 classify something as a public good if 163 00:08:57.179 --> 00:09:00.540 it is both non-excludable and non-rival 164 00:09:00.540 --> 00:09:03.600 risks now I know these terms are quite a 165 00:09:03.600 --> 00:09:05.339 mouthful but they are fairly simple 166 00:09:05.339 --> 00:09:09.080 ideas let's start with non-excludable 167 00:09:09.080 --> 00:09:11.458 non-excludable means that it is either 168 00:09:11.458 --> 00:09:13.980 expensive or nearly impossible to 169 00:09:13.980 --> 00:09:16.160 exclude someone from using the good 170 00:09:16.160 --> 00:09:19.260 let's say an individual who we will call 171 00:09:19.260 --> 00:09:22.080 Larry buys a private good like a piece 172 00:09:22.080 --> 00:09:25.200 of pizza then he can exclude others from 173 00:09:25.200 --> 00:09:27.899 eating that pizza however if National 174 00:09:27.899 --> 00:09:29.940 Defense is being provided then it 175 00:09:29.940 --> 00:09:32.399 includes everyone if you strongly 176 00:09:32.399 --> 00:09:34.080 disagree with your country's defense 177 00:09:34.080 --> 00:09:36.600 policies the National Defense still 178 00:09:36.600 --> 00:09:39.179 protects you you cannot choose to be 179 00:09:39.179 --> 00:09:42.000 unprotected and National Defense cannot 180 00:09:42.000 --> 00:09:44.040 protect everyone else and exclude you 181 00:09:44.040 --> 00:09:46.740 the second main characteristic of a 182 00:09:46.740 --> 00:09:48.660 public good is that it is non-rival 183 00:09:48.660 --> 00:09:51.000 risks which means that when one person 184 00:09:51.000 --> 00:09:53.279 uses the public good another can also 185 00:09:53.279 --> 00:09:56.880 use it with a private good like pizza if 186 00:09:56.880 --> 00:09:58.740 our subject Larry is eating the pizza 187 00:09:58.740 --> 00:10:01.860 then another person cannot eat it that 188 00:10:01.860 --> 00:10:03.958 is the two people are rivals in 189 00:10:03.958 --> 00:10:06.059 consumption with a public good like 190 00:10:06.059 --> 00:10:08.700 National Defense Larry's consumption of 191 00:10:08.700 --> 00:10:10.740 National Defense does not reduce the 192 00:10:10.740 --> 00:10:12.600 amount for others so they are 193 00:10:12.600 --> 00:10:14.940 non-rivalrous in this area 194 00:10:14.940 --> 00:10:17.760 a number of government services are also 195 00:10:17.760 --> 00:10:20.820 examples of public goods for instance it 196 00:10:20.820 --> 00:10:22.800 would not be easy to provide Fire and 197 00:10:22.800 --> 00:10:24.540 Police Service for some people in a 198 00:10:24.540 --> 00:10:26.540 given neighborhood but not everyone 199 00:10:26.540 --> 00:10:29.279 protecting some necessarily means 200 00:10:29.279 --> 00:10:31.920 protecting others too paying for public 201 00:10:31.920 --> 00:10:34.140 goods is always a challenging dilemma 202 00:10:34.140 --> 00:10:35.760 for both Business Leaders and 203 00:10:35.760 --> 00:10:38.580 politicians the key Insight in paying 204 00:10:38.580 --> 00:10:40.920 for public goods is to find a way of 205 00:10:40.920 --> 00:10:42.720 assuring that everyone will make a 206 00:10:42.720 --> 00:10:45.958 contribution for example if people come 207 00:10:45.958 --> 00:10:47.880 together through the political process 208 00:10:47.880 --> 00:10:50.640 and agree to pay taxes and make group 209 00:10:50.640 --> 00:10:52.500 decisions about the quantity of public 210 00:10:52.500 --> 00:10:54.839 goods then they can all feel like they 211 00:10:54.839 --> 00:10:56.399 are being treated equally because 212 00:10:56.399 --> 00:10:59.519 everyone contributes 213 00:10:59.519 --> 00:11:02.578 now answer the questions 214 00:11:02.578 --> 00:11:03.779 one 215 00:11:03.779 --> 00:11:07.820 what is the lecture mainly about 216 00:11:30.059 --> 00:11:31.140 two 217 00:11:31.140 --> 00:11:35.399 how is the lecture organized 218 00:12:05.220 --> 00:12:07.860 three based on the information from the 219 00:12:07.860 --> 00:12:10.140 listening indicate which characteristic 220 00:12:10.140 --> 00:12:11.958 on the left belongs to either 221 00:12:11.958 --> 00:12:16.140 non-excludable non-rival or neither this 222 00:12:16.140 --> 00:12:20.000 question is worth two points 223 00:12:49.440 --> 00:12:53.120 four what is an example of a public good 224 00:12:53.120 --> 00:12:56.420 select two 225 00:13:25.860 --> 00:13:27.179 five 226 00:13:27.179 --> 00:13:29.578 what is the professor implying when she 227 00:13:29.578 --> 00:13:31.500 says this 228 00:13:31.500 --> 00:13:34.040 so besides being hard to separate 229 00:13:34.040 --> 00:13:36.839 economists usually classify something as 230 00:13:36.839 --> 00:13:38.480 a public good if it is both 231 00:13:38.480 --> 00:13:42.480 non-excludable and non-rival risks now I 232 00:13:42.480 --> 00:13:44.339 know these terms are quite a mouthful 233 00:13:44.339 --> 00:13:48.260 but they are fairly simple ideas 234 00:14:17.578 --> 00:14:19.139 six 235 00:14:19.139 --> 00:14:21.660 why does the professor talk about pizza 236 00:14:21.660 --> 00:14:25.040 during the lecture 237 00:14:54.640 --> 00:14:57.700 [Music] 238 00:14:59.760 --> 00:15:02.880 now listen to part of a talk in a 239 00:15:02.880 --> 00:15:05.540 psychology class 240 00:15:06.000 --> 00:15:08.100 now that we're on the topic of memory 241 00:15:08.100 --> 00:15:10.680 it's a good time to talk about the case 242 00:15:10.680 --> 00:15:14.519 of Henry mullison okay so where to start 243 00:15:14.519 --> 00:15:15.779 well 244 00:15:15.779 --> 00:15:19.139 Henry mullison was better known as hm in 245 00:15:19.139 --> 00:15:21.959 the scientific Community you see he's 246 00:15:21.959 --> 00:15:25.139 probably no definitely the most 247 00:15:25.139 --> 00:15:27.300 important patient in the history of 248 00:15:27.300 --> 00:15:28.680 Neuroscience 249 00:15:28.680 --> 00:15:31.560 before his death in 2008 mullison was 250 00:15:31.560 --> 00:15:34.380 the subject of over 1200 research 251 00:15:34.380 --> 00:15:35.519 articles 252 00:15:35.519 --> 00:15:40.380 so what made hm so special well a little 253 00:15:40.380 --> 00:15:42.180 background about his life 254 00:15:42.180 --> 00:15:45.060 Mollison had epilepsy which is when you 255 00:15:45.060 --> 00:15:47.339 lose control of much of your body and 256 00:15:47.339 --> 00:15:49.139 start having seizures 257 00:15:49.139 --> 00:15:52.800 while by the age of 27 hm seizures were 258 00:15:52.800 --> 00:15:55.440 getting much worse in an attempt to 259 00:15:55.440 --> 00:15:58.620 control his seizures hm underwent brain 260 00:15:58.620 --> 00:16:01.380 surgery to remove very important pieces 261 00:16:01.380 --> 00:16:04.920 of his brain his hippocampus and his 262 00:16:04.920 --> 00:16:08.040 amygdala now put that on the board here 263 00:16:08.040 --> 00:16:09.959 so the doctor in charge of this 264 00:16:09.959 --> 00:16:11.940 procedure believed it would cure his 265 00:16:11.940 --> 00:16:15.000 epilepsy well he was right in that hm 266 00:16:15.000 --> 00:16:17.519 seizures almost completely stopped 267 00:16:17.519 --> 00:16:21.060 but there was an even more drastic and 268 00:16:21.060 --> 00:16:23.220 devastating consequence of this 269 00:16:23.220 --> 00:16:24.420 procedure 270 00:16:24.420 --> 00:16:28.019 mullison lost his ability to create new 271 00:16:28.019 --> 00:16:29.279 memories 272 00:16:29.279 --> 00:16:31.320 this is referred to in medical 273 00:16:31.320 --> 00:16:34.079 terminology as severe enterograde 274 00:16:34.079 --> 00:16:36.480 Amnesia and I'll put that on the board 275 00:16:36.480 --> 00:16:37.500 too 276 00:16:37.500 --> 00:16:40.740 you see Henry no longer had the ability 277 00:16:40.740 --> 00:16:43.440 to make conscious memories of specific 278 00:16:43.440 --> 00:16:45.839 facts like names dates and recent 279 00:16:45.839 --> 00:16:48.540 happenings so if you introduced yourself 280 00:16:48.540 --> 00:16:50.959 to Henry at any time after the surgery 281 00:16:50.959 --> 00:16:53.420 within 30 seconds of your introduction 282 00:16:53.420 --> 00:16:56.639 he would completely forget ever meeting 283 00:16:56.639 --> 00:16:59.639 you hm would wake up every day in the 284 00:16:59.639 --> 00:17:01.860 same state of mind he had before the 285 00:17:01.860 --> 00:17:02.880 surgery 286 00:17:02.880 --> 00:17:06.720 he could not make any new conscious 287 00:17:06.720 --> 00:17:08.280 memories 288 00:17:08.280 --> 00:17:11.579 in 1962 about 10 years after his surgery 289 00:17:11.579 --> 00:17:14.760 a young surgeon named Suzanne corkin met 290 00:17:14.760 --> 00:17:17.699 hm and realized that while a tragedy in 291 00:17:17.699 --> 00:17:20.880 most respects hm's condition provided 292 00:17:20.880 --> 00:17:23.699 her with a unique opportunity to analyze 293 00:17:23.699 --> 00:17:26.459 the function of specific areas of the 294 00:17:26.459 --> 00:17:28.679 brain and how they relate to learning 295 00:17:28.679 --> 00:17:30.119 and memory 296 00:17:30.119 --> 00:17:32.220 even though he suffered from Amnesia 297 00:17:32.220 --> 00:17:34.679 much of Henry's brain function besides 298 00:17:34.679 --> 00:17:37.260 memory remained intact he was a friendly 299 00:17:37.260 --> 00:17:40.020 guy also since he had almost no 300 00:17:40.020 --> 00:17:42.359 short-term memory ability he would never 301 00:17:42.359 --> 00:17:44.580 get tired of the boring brain activities 302 00:17:44.580 --> 00:17:46.740 needed for the research 303 00:17:46.740 --> 00:17:49.500 studying hm's brain led to some 304 00:17:49.500 --> 00:17:51.660 fascinating discoveries in the field of 305 00:17:51.660 --> 00:17:54.240 Neuroscience up until the 20th century 306 00:17:54.240 --> 00:17:55.919 Neuroscience had very little 307 00:17:55.919 --> 00:17:58.700 understanding of how the brain worked 308 00:17:58.700 --> 00:18:02.039 hm's rewired brain quickly proved that 309 00:18:02.039 --> 00:18:04.380 memory was not spread throughout the 310 00:18:04.380 --> 00:18:07.500 brain Henry's acute anterograde Amnesia 311 00:18:07.500 --> 00:18:09.240 had little effect on his self-knowledge 312 00:18:09.240 --> 00:18:12.720 or intelligence prior to the age of 25. 313 00:18:12.720 --> 00:18:15.359 Henry's case and others like it soon 314 00:18:15.359 --> 00:18:17.580 revealed that declarative long-term 315 00:18:17.580 --> 00:18:20.039 memories are stored in the area of the 316 00:18:20.039 --> 00:18:23.100 brain known as the hippocampus 317 00:18:23.100 --> 00:18:26.220 through hm researchers discovered that 318 00:18:26.220 --> 00:18:28.679 the brain possesses multiple systems for 319 00:18:28.679 --> 00:18:30.960 storing and retrieving memories that are 320 00:18:30.960 --> 00:18:33.359 dispersed in different but specific 321 00:18:33.359 --> 00:18:37.200 locations in the brain hm could not form 322 00:18:37.200 --> 00:18:40.020 any new conscious memories after his 323 00:18:40.020 --> 00:18:42.960 surgery but he could improve on his 324 00:18:42.960 --> 00:18:45.539 ability to perform tasks 325 00:18:45.539 --> 00:18:47.880 it soon became clear that the brain had 326 00:18:47.880 --> 00:18:50.340 another type of memory system called 327 00:18:50.340 --> 00:18:53.580 muscle memory which did not rely on 328 00:18:53.580 --> 00:18:55.020 conscious memories 329 00:18:55.020 --> 00:18:57.780 in one of her experiments corkin would 330 00:18:57.780 --> 00:18:59.880 have hm sketch a figure through the 331 00:18:59.880 --> 00:19:02.160 reflection of a mirror this is a 332 00:19:02.160 --> 00:19:04.020 challenging task that takes time to 333 00:19:04.020 --> 00:19:05.820 practice and master 334 00:19:05.820 --> 00:19:08.359 mullison had developed a new skill 335 00:19:08.359 --> 00:19:11.580 subconsciously through repetition 336 00:19:11.580 --> 00:19:13.919 sometimes referred to as motor learning 337 00:19:13.919 --> 00:19:17.220 hm confirmed that new skills can be 338 00:19:17.220 --> 00:19:20.179 learned through repetition over time 339 00:19:20.179 --> 00:19:22.559 disassociated from conscious memories 340 00:19:22.559 --> 00:19:24.539 this doesn't mean that skills like 341 00:19:24.539 --> 00:19:26.700 playing the piano or drawing a face rely 342 00:19:26.700 --> 00:19:29.820 solely on muscle memory however it plays 343 00:19:29.820 --> 00:19:32.039 a much bigger role in our retention of 344 00:19:32.039 --> 00:19:35.520 skills than previously suspected while 345 00:19:35.520 --> 00:19:37.380 there were some benefits for research 346 00:19:37.380 --> 00:19:39.720 Henry's unique Amnesia made it almost 347 00:19:39.720 --> 00:19:42.359 impossible for him to remember any new 348 00:19:42.359 --> 00:19:45.720 events after the surgery for example the 349 00:19:45.720 --> 00:19:47.580 death of his parents occurred later in 350 00:19:47.580 --> 00:19:48.539 his life 351 00:19:48.539 --> 00:19:50.820 and he couldn't remember it 352 00:19:50.820 --> 00:19:52.799 whenever he was reminded of his parents 353 00:19:52.799 --> 00:19:55.980 demise the pain returned as if he were 354 00:19:55.980 --> 00:20:00.320 hearing it again for the first time 355 00:20:01.140 --> 00:20:03.780 now answer the questions 356 00:20:03.780 --> 00:20:05.039 one 357 00:20:05.039 --> 00:20:08.960 what is the lecture mainly about 358 00:20:39.059 --> 00:20:42.419 two how does the professor organize the 359 00:20:42.419 --> 00:20:44.840 lecture 360 00:21:13.799 --> 00:21:16.619 three what does the professor imply 361 00:21:16.619 --> 00:21:20.959 about Henry mollison's situation 362 00:21:50.159 --> 00:21:53.400 4. after his surgery why would Henry 363 00:21:53.400 --> 00:21:55.859 Mollison forget about meeting someone 30 364 00:21:55.859 --> 00:21:58.519 seconds later 365 00:22:27.659 --> 00:22:31.020 five how is Henry Mollison able to 366 00:22:31.020 --> 00:22:34.640 develop new skills 367 00:23:03.419 --> 00:23:07.500 six why does the professor say this 368 00:23:07.500 --> 00:23:11.100 in an attempt to control his seizures hm 369 00:23:11.100 --> 00:23:13.799 underwent brain surgery to remove very 370 00:23:13.799 --> 00:23:16.740 important pieces of his brain his 371 00:23:16.740 --> 00:23:19.619 hippocampus and his amygdala I'll put 372 00:23:19.619 --> 00:23:22.339 that on the board here 373 00:23:57.480 --> 00:24:00.840 now listen to a conversation between a 374 00:24:00.840 --> 00:24:04.580 student and an I.T worker 375 00:24:04.919 --> 00:24:07.500 hi I have a big problem that I need your 376 00:24:07.500 --> 00:24:10.559 help with what's going on well I was 377 00:24:10.559 --> 00:24:12.059 just at the library to print some stuff 378 00:24:12.059 --> 00:24:14.100 off for class and when I went to open my 379 00:24:14.100 --> 00:24:15.840 laptop and get started the screen went 380 00:24:15.840 --> 00:24:17.760 blank and all these funny symbols 381 00:24:17.760 --> 00:24:20.039 started showing up then my computer just 382 00:24:20.039 --> 00:24:22.380 turned off I don't know what to do my 383 00:24:22.380 --> 00:24:24.299 computer won't turn back on I'm scared 384 00:24:24.299 --> 00:24:26.220 that something bad happened like a virus 385 00:24:26.220 --> 00:24:29.580 or it crashed oh dear that sounds like a 386 00:24:29.580 --> 00:24:31.619 potential virus to me let me take a look 387 00:24:31.619 --> 00:24:33.359 at your computer so I can try and scan 388 00:24:33.359 --> 00:24:35.100 and find the problem did you back up 389 00:24:35.100 --> 00:24:37.380 your work you know what it's really 390 00:24:37.380 --> 00:24:39.780 weird but I actually just backed up 391 00:24:39.780 --> 00:24:41.760 everything this morning onto my external 392 00:24:41.760 --> 00:24:43.440 hard drive which I haven't done in a 393 00:24:43.440 --> 00:24:45.659 really long time it's like I just had a 394 00:24:45.659 --> 00:24:47.039 feeling something was going to happen 395 00:24:47.039 --> 00:24:48.960 and now I can't believe that something 396 00:24:48.960 --> 00:24:51.119 actually is wrong 397 00:24:51.119 --> 00:24:52.919 that's really lucky that you backed 398 00:24:52.919 --> 00:24:54.900 everything up because in this situation 399 00:24:54.900 --> 00:24:56.700 who knows if you'll be able to get 400 00:24:56.700 --> 00:24:59.039 everything back it will take time for me 401 00:24:59.039 --> 00:25:00.480 to scan it and see what's the problem 402 00:25:00.480 --> 00:25:03.119 hopefully I won't have to but I may need 403 00:25:03.119 --> 00:25:04.919 to clean the hard drive in which case 404 00:25:04.919 --> 00:25:06.960 you would lose any information on your 405 00:25:06.960 --> 00:25:09.359 computer if you prefer you can take it 406 00:25:09.359 --> 00:25:10.740 to the company where you bought your 407 00:25:10.740 --> 00:25:12.480 computer and have them take a look but 408 00:25:12.480 --> 00:25:14.100 that could cost you at least five 409 00:25:14.100 --> 00:25:17.520 hundred dollars that's crazy I trust you 410 00:25:17.520 --> 00:25:18.900 though and I think whatever you decide 411 00:25:18.900 --> 00:25:21.359 is best that's what I'll do I don't want 412 00:25:21.359 --> 00:25:22.980 to spend five hundred dollars if they're 413 00:25:22.980 --> 00:25:24.539 just going to tell me the same thing you 414 00:25:24.539 --> 00:25:27.539 would okay I'll go ahead and keep your 415 00:25:27.539 --> 00:25:29.220 computer here and I'll send you an email 416 00:25:29.220 --> 00:25:31.260 when the scan is done and I'll find out 417 00:25:31.260 --> 00:25:32.880 what's going on and what can be done to 418 00:25:32.880 --> 00:25:35.100 fix it do you know how long that's going 419 00:25:35.100 --> 00:25:37.140 to take I still need to print some files 420 00:25:37.140 --> 00:25:38.220 for class 421 00:25:38.220 --> 00:25:40.980 well I can't say for sure but I think 422 00:25:40.980 --> 00:25:42.600 you should take your external hard drive 423 00:25:42.600 --> 00:25:44.580 to the library and print your files off 424 00:25:44.580 --> 00:25:46.520 at the library computers in the meantime 425 00:25:46.520 --> 00:25:48.840 besides if I have to swipe your hard 426 00:25:48.840 --> 00:25:50.400 drive there won't be anything on your 427 00:25:50.400 --> 00:25:52.919 laptop to print that's true well at 428 00:25:52.919 --> 00:25:54.900 least that fires put out now I just have 429 00:25:54.900 --> 00:25:56.400 to worry about my computer getting back 430 00:25:56.400 --> 00:25:58.760 to normal 431 00:25:59.400 --> 00:26:02.100 now answer the questions 432 00:26:02.100 --> 00:26:07.220 one problem is the student having 433 00:26:36.779 --> 00:26:40.200 two what does the it worker imply when 434 00:26:40.200 --> 00:26:42.419 she tells the student he is lucky that 435 00:26:42.419 --> 00:26:45.559 he backed up his files 436 00:27:15.059 --> 00:27:17.700 three listen again to part of the 437 00:27:17.700 --> 00:27:18.659 passage 438 00:27:18.659 --> 00:27:21.119 what does the student mean when he says 439 00:27:21.119 --> 00:27:23.039 this 440 00:27:23.039 --> 00:27:25.260 that's true well at least that Fire's 441 00:27:25.260 --> 00:27:27.059 put out now I just have to worry about 442 00:27:27.059 --> 00:27:30.440 my computer getting back to normal 443 00:27:59.700 --> 00:28:03.480 four listen again to part of the passage 444 00:28:03.480 --> 00:28:06.000 what does the it worker imply when she 445 00:28:06.000 --> 00:28:08.658 says this 446 00:28:11.760 --> 00:28:14.820 have them take a look but 447 00:28:14.820 --> 00:28:17.539 dollars 448 00:28:46.320 --> 00:28:49.320 five when will the it worker be done 449 00:28:49.320 --> 00:28:52.880 fixing the student's computer 450 00:29:22.440 --> 00:29:25.159 foreign 451 00:29:27.539 --> 00:29:30.600 now listen it's a part of a talk in a 452 00:29:30.600 --> 00:29:33.379 Sociology class 453 00:29:34.440 --> 00:29:36.899 we are going to discuss marriage and 454 00:29:36.899 --> 00:29:39.059 more importantly we want to study how 455 00:29:39.059 --> 00:29:41.399 the idea of marriage interacts with a 456 00:29:41.399 --> 00:29:44.039 society as a whole in other words we 457 00:29:44.039 --> 00:29:46.140 want to know how observing marriages in 458 00:29:46.140 --> 00:29:48.360 different cultures can help us learn a 459 00:29:48.360 --> 00:29:50.880 bit more about the larger community 460 00:29:50.880 --> 00:29:54.179 so when we sociologists want to study 461 00:29:54.179 --> 00:29:56.220 families we must first have a 462 00:29:56.220 --> 00:29:59.039 perspective a kind of lens to look 463 00:29:59.039 --> 00:30:01.020 through you might remember from the 464 00:30:01.020 --> 00:30:03.720 reading the idea of functionalism in 465 00:30:03.720 --> 00:30:06.480 sociology functionalism is when you look 466 00:30:06.480 --> 00:30:08.940 at a society and individuals within a 467 00:30:08.940 --> 00:30:11.820 society as filling a role or a function 468 00:30:11.820 --> 00:30:14.640 they have to serve some purpose 469 00:30:14.640 --> 00:30:17.820 let's use this lens the perspective of 470 00:30:17.820 --> 00:30:21.059 functionalism to examine marriage when 471 00:30:21.059 --> 00:30:22.980 considering the role of families and 472 00:30:22.980 --> 00:30:25.440 societies functionalists believe that 473 00:30:25.440 --> 00:30:28.080 they play a key role in stabilizing the 474 00:30:28.080 --> 00:30:30.539 culture the family performs certain 475 00:30:30.539 --> 00:30:32.820 tasks that help a society grow and 476 00:30:32.820 --> 00:30:33.720 develop 477 00:30:33.720 --> 00:30:36.419 after a series of tests sociologist 478 00:30:36.419 --> 00:30:39.419 George Murdoch has determined that there 479 00:30:39.419 --> 00:30:41.279 are three Universal functions of the 480 00:30:41.279 --> 00:30:42.120 family 481 00:30:42.120 --> 00:30:45.720 sexual reproductive and educational 482 00:30:45.720 --> 00:30:48.600 according to Murdoch the family which 483 00:30:48.600 --> 00:30:50.659 for him includes the state of marriage 484 00:30:50.659 --> 00:30:53.100 regulates sexual relations between 485 00:30:53.100 --> 00:30:55.559 individuals he does not deny the 486 00:30:55.559 --> 00:30:58.140 existence of sex outside of marriage but 487 00:30:58.140 --> 00:31:00.240 states that the family offers a socially 488 00:31:00.240 --> 00:31:03.179 approved sexual outlet for adults this 489 00:31:03.179 --> 00:31:05.399 Outlet gives way to reproduction which 490 00:31:05.399 --> 00:31:07.500 is a necessary part of ensuring the 491 00:31:07.500 --> 00:31:10.320 survival of society once children are 492 00:31:10.320 --> 00:31:12.899 produced the family plays a vital role 493 00:31:12.899 --> 00:31:15.480 in training them for adult life the 494 00:31:15.480 --> 00:31:17.520 family teaches young children the ways 495 00:31:17.520 --> 00:31:19.740 of thinking and behaving that follows 496 00:31:19.740 --> 00:31:22.039 social and cultural values and beliefs 497 00:31:22.039 --> 00:31:24.779 basically parents teach their children 498 00:31:24.779 --> 00:31:27.179 how to be good citizens in a given 499 00:31:27.179 --> 00:31:29.700 culture but that's just the functional 500 00:31:29.700 --> 00:31:31.860 perspective there are other lenses to 501 00:31:31.860 --> 00:31:32.820 look through 502 00:31:32.820 --> 00:31:35.940 conflict theory looks at a society as a 503 00:31:35.940 --> 00:31:38.159 constant state of fighting since two 504 00:31:38.159 --> 00:31:41.100 individuals families governments and so 505 00:31:41.100 --> 00:31:43.380 on are competing for a limited number of 506 00:31:43.380 --> 00:31:46.320 resources conflict theorists are quick 507 00:31:46.320 --> 00:31:48.299 to point out that American families have 508 00:31:48.299 --> 00:31:50.580 a more individualistic style of thinking 509 00:31:50.580 --> 00:31:52.980 many Americans are resistant to 510 00:31:52.980 --> 00:31:54.500 government intervention in the family 511 00:31:54.500 --> 00:31:56.760 parents do not want the government to 512 00:31:56.760 --> 00:31:59.039 tell them how to raise their children or 513 00:31:59.039 --> 00:32:01.039 to become involved in domestic issues 514 00:32:01.039 --> 00:32:03.539 conflict theory highlights the role of 515 00:32:03.539 --> 00:32:05.520 power in family life and that 516 00:32:05.520 --> 00:32:07.440 individuals within families are 517 00:32:07.440 --> 00:32:09.720 constantly struggling for control 518 00:32:09.720 --> 00:32:11.580 let's look at the division of labor 519 00:32:11.580 --> 00:32:13.399 within the family home as an example 520 00:32:13.399 --> 00:32:16.260 most family members don't get paid for 521 00:32:16.260 --> 00:32:18.179 washing dishes and vacuuming carpets 522 00:32:18.179 --> 00:32:21.360 however studies indicate that when men 523 00:32:21.360 --> 00:32:24.120 do more housework women experience more 524 00:32:24.120 --> 00:32:26.580 satisfaction in their marriages reducing 525 00:32:26.580 --> 00:32:28.860 the incidence of conflict and increasing 526 00:32:28.860 --> 00:32:31.559 the Woman's power in general conflict 527 00:32:31.559 --> 00:32:33.779 theorists tend to study areas of 528 00:32:33.779 --> 00:32:35.220 marriage and life that involve 529 00:32:35.220 --> 00:32:38.159 inequalities in power and authority as 530 00:32:38.159 --> 00:32:40.020 they are reflective of the larger social 531 00:32:40.020 --> 00:32:42.960 structure now there is one more popular 532 00:32:42.960 --> 00:32:45.360 lens that many sociologists look through 533 00:32:45.360 --> 00:32:48.620 and that symbolic interactionism 534 00:32:48.620 --> 00:32:51.240 interactionists view the world in terms 535 00:32:51.240 --> 00:32:53.159 of symbols and the meanings assigned to 536 00:32:53.159 --> 00:32:56.399 them the Family itself is a symbol just 537 00:32:56.399 --> 00:32:58.799 some it is a father mother and children 538 00:32:58.799 --> 00:33:01.740 to others it's any Union that involves 539 00:33:01.740 --> 00:33:03.620 respect and compassion 540 00:33:03.620 --> 00:33:06.179 interactionists stress that family is a 541 00:33:06.179 --> 00:33:08.039 social phenomenon that changes meaning 542 00:33:08.039 --> 00:33:11.100 based on the time place and culture 543 00:33:11.100 --> 00:33:13.500 consider what it means to be a father or 544 00:33:13.500 --> 00:33:16.380 a mother at one time it was a symbol of 545 00:33:16.380 --> 00:33:19.260 biological connection to a child however 546 00:33:19.260 --> 00:33:22.019 many children now are no longer raised 547 00:33:22.019 --> 00:33:24.120 by their biological parents but still 548 00:33:24.120 --> 00:33:26.179 call them mother and father 549 00:33:26.179 --> 00:33:28.679 interactionists also realize how the 550 00:33:28.679 --> 00:33:30.600 roles within families are socially 551 00:33:30.600 --> 00:33:31.820 constructed 552 00:33:31.820 --> 00:33:34.140 interactionists view the family as a 553 00:33:34.140 --> 00:33:36.960 group of role players or actors that 554 00:33:36.960 --> 00:33:39.000 come together to act out their parts in 555 00:33:39.000 --> 00:33:41.760 an effort to construct a family these 556 00:33:41.760 --> 00:33:44.279 roles are up for interpretation 557 00:33:44.279 --> 00:33:47.159 now just to recap if we view the family 558 00:33:47.159 --> 00:33:49.140 through a functional lens then we see 559 00:33:49.140 --> 00:33:51.419 actions based on how it contributes to a 560 00:33:51.419 --> 00:33:54.059 society as a whole if we look through a 561 00:33:54.059 --> 00:33:56.460 conflict theory lens then we see family 562 00:33:56.460 --> 00:33:58.440 interactions as a power struggle between 563 00:33:58.440 --> 00:34:00.899 individuals and if we look through the 564 00:34:00.899 --> 00:34:03.360 symbolic interactionist lens then we 565 00:34:03.360 --> 00:34:05.519 view the actions of families as filling 566 00:34:05.519 --> 00:34:07.740 a role they are expected to play and 567 00:34:07.740 --> 00:34:09.960 that role can change over time 568 00:34:09.960 --> 00:34:12.239 which one do you think is the most 569 00:34:12.239 --> 00:34:14.159 useful perspective to have on 570 00:34:14.159 --> 00:34:16.980 Contemporary American marriages now 571 00:34:16.980 --> 00:34:18.899 answer the questions 572 00:34:18.899 --> 00:34:20.159 one 573 00:34:20.159 --> 00:34:24.200 what is the lecture mainly about 574 00:34:53.339 --> 00:34:54.599 two 575 00:34:54.599 --> 00:34:56.760 why does the professor discuss 576 00:34:56.760 --> 00:35:01.440 sociologist George Murdoch 577 00:35:30.839 --> 00:35:35.900 three how is the lecture organized 578 00:36:04.700 --> 00:36:07.680 4. the professor discusses several 579 00:36:07.680 --> 00:36:10.560 perspectives on marriage and family unit 580 00:36:10.560 --> 00:36:13.380 indicate which information matches each 581 00:36:13.380 --> 00:36:15.960 type of perspective this question is 582 00:36:15.960 --> 00:36:19.098 worth two points 583 00:36:48.719 --> 00:36:49.859 five 584 00:36:49.859 --> 00:36:52.680 according to sociologist George Murdoch 585 00:36:52.680 --> 00:36:54.960 what are the three Universal functions 586 00:36:54.960 --> 00:36:57.680 of the family 587 00:37:27.239 --> 00:37:31.200 six why does the professor say this 588 00:37:31.200 --> 00:37:33.540 which one do you think is the most 589 00:37:33.540 --> 00:37:35.460 useful perspective to have on 590 00:37:35.460 --> 00:37:39.140 Contemporary American marriages 591 00:38:07.820 --> 00:38:10.380 all right
