1
00:00:09,039 --> 00:00:11,529
David Merell whose is a student

2
00:00:12,329 --> 00:00:15,549
In Virginia and he did a experiment

3
00:00:15,873 --> 00:00:18,183
we did an experiment and I just called it

4
00:00:18,306 --> 00:00:22,566
in my own notes the destructive effect

5
00:00:22,566 --> 00:00:25,696
of rock and the salutary of effect

6
00:00:25,696 --> 00:00:28,176
of classical music and i think i will

7
00:00:28,176 --> 00:00:30,496
just have David come up and explain to

8
00:00:30,496 --> 00:00:32,926
you what he did and what his experiment

9
00:00:32,926 --> 00:00:34,736
was and what it demonstrated

10
00:00:35,024 --> 00:00:39,024
So David

11
00:01:15,760 --> 00:01:17,430
David: Good Morning

12
00:01:17,683 --> 00:01:19,313
First of all I Just like to say

13
00:01:19,363 --> 00:01:21,823
thank you to Mrs. Ogdmen for inviting me

14
00:01:21,845 --> 00:01:23,875
here to be able to speak to you this

15
00:01:23,876 --> 00:01:29,886
morning and I would like to um say thank

16
00:01:29,886 --> 00:01:31,836
you for the wonderful introduction as

17
00:01:31,836 --> 00:01:34,026
he said my name is David Merell I'm a

18
00:01:34,026 --> 00:01:36,156
Junior or senior at Nansemond River

19
00:01:36,156 --> 00:01:38,176
High school and i received a lot of

20
00:01:38,186 --> 00:01:40,936
recognition for this project which I'm

21
00:01:40,936 --> 00:01:45,266
here today to tell you about

22
00:01:45,266 --> 00:01:48,313
I Guess i can start off by

23
00:01:48,313 --> 00:02:00,793
*inaudible Speaking from the crowd

24
00:02:00,793 --> 00:02:04,423
David : Hows that Is that, is that better

25
00:02:04,423 --> 00:02:08,003
Okay Alright As i said my name is

26
00:02:08,003 --> 00:02:10,813
David Merrel and I' here to tell you about

27
00:02:10,813 --> 00:02:13,023
an experiment that i received a lot of

28
00:02:13,023 --> 00:02:17,193
recognition for. I have been brought up

29
00:02:17,193 --> 00:02:19,093
In my family and my family has been

30
00:02:19,093 --> 00:02:22,343
big on music they, they seen, what

31
00:02:22,343 --> 00:02:24,633
you know the big effect that music can

32
00:02:24,633 --> 00:02:26,943
have on the use of today and on society.

33
00:02:27,736 --> 00:02:29,886
and they always brought me up teaching me

34
00:02:29,886 --> 00:02:33,806
that heavy metal that sort of music

35
00:02:33,806 --> 00:02:36,086
really isn't good for ya and that

36
00:02:36,088 --> 00:02:39,478
classical music is something that is good

37
00:02:39,478 --> 00:02:42,068
There's nothing bad about it and just to

38
00:02:42,068 --> 00:02:44,238
In general realize just how powerful

39
00:02:44,238 --> 00:02:46,528
music is and I have been doing research

40
00:02:46,565 --> 00:02:48,915
and our family is , you know has books

41
00:02:48,931 --> 00:02:51,521
and things like that about music

42
00:02:51,521 --> 00:02:53,971
and one day we came across this research

43
00:02:53,971 --> 00:02:56,411
that Michael Bowlen about how he used

44
00:02:56,411 --> 00:03:01,561
music he used classical music and atonal

45
00:03:01,583 --> 00:03:04,523
sounds on groups of mice and ran them

46
00:03:04,523 --> 00:03:07,393
through a maze to see what, what the

47
00:03:07,403 --> 00:03:08,783
effects would have on them and I said

48
00:03:08,783 --> 00:03:11,919
that pretty neat, so I came up with a

49
00:03:11,919 --> 00:03:14,339
project or devised a project that would

50
00:03:14,339 --> 00:03:17,269
somewhat simulate a learning environment

51
00:03:17,839 --> 00:03:20,689
for mice for what I did or the title of

52
00:03:20,689 --> 00:03:22,909
the project is music mice amazes the

53
00:03:22,909 --> 00:03:24,349
classic rock is growing that continues

54
00:03:24,349 --> 00:03:26,759
this is a, this actually second year that

55
00:03:26,759 --> 00:03:30,179
i have done this project

56
00:03:30,179 --> 00:03:32,909
in this project my hypothesis was that.

57
00:03:33,416 --> 00:03:35,126
Music would have an effect on the

58
00:03:35,126 --> 00:03:37,131
learning abilities of white male mice

59
00:03:37,131 --> 00:03:39,301
classical music will have a positive

60
00:03:39,301 --> 00:03:41,941
effect whereas hardrock music will have

61
00:03:41,941 --> 00:03:44,901
a negative effect and as I said this is

62
00:03:44,901 --> 00:03:47,721
Second year I've done this project and the 1st year.

63
00:03:47,721 --> 00:03:49,911
I did this project I obtained eighteen

64
00:03:49,911 --> 00:03:52,401
white male mice from a local pet store.

65
00:03:52,802 --> 00:03:54,682
and divided them into three different

66
00:03:54,682 --> 00:03:57,172
groups. A hardrock group or heavy metal

67
00:03:57,172 --> 00:03:59,502
group which would listen to Anthrax,

68
00:03:59,502 --> 00:04:03,732
stunt 442 and at the time since we really

69
00:04:03,732 --> 00:04:06,322
didnt know any good heavy metal groups we

70
00:04:06,322 --> 00:04:08,312
just went to K-Mart and ask the clerk

71
00:04:08,312 --> 00:04:10,472
behind the desk whats a good heavy metal

72
00:04:10,472 --> 00:04:12,862
group and she handed us this CD and after

73
00:04:12,862 --> 00:04:15,052
about ten seconds of listening to it

74
00:04:15,052 --> 00:04:16,922
we found that's the one wanted

75
00:04:16,922 --> 00:04:18,952
*crowd is laughing from David joke

76
00:04:18,952 --> 00:04:22,704
Um we then ah, we also had a classical

77
00:04:22,704 --> 00:04:27,094
group. Which we played a variety of different classical

78
00:04:27,094 --> 00:04:28,734
songs to it, it didn't matter which ones

79
00:04:28,734 --> 00:04:31,194
as long as it was classical. So we divided

80
00:04:31,194 --> 00:04:33,074
this mice into three different groups

81
00:04:33,074 --> 00:04:34,834
and we began running them through a fixed

82
00:04:34,834 --> 00:04:38,014
maze over the course of the next four weeks

83
00:04:38,014 --> 00:04:40,926
and as time progressed the mice either

84
00:04:40,926 --> 00:04:44,936
got faster or slower and ah the classical

85
00:04:45,010 --> 00:04:47,790
or I'll go into that later. But

86
00:04:47,790 --> 00:04:49,161
the interesting thing about first year

87
00:04:49,161 --> 00:04:51,201
I did this project is that actually I

88
00:04:51,201 --> 00:04:53,611
had to cut it short because the heavy

89
00:04:53,611 --> 00:04:56,481
music had made these mice who can't

90
00:04:56,481 --> 00:04:59,291
understand words just the sounds alone

91
00:04:59,291 --> 00:05:01,851
had made them so violent that within

92
00:05:01,851 --> 00:05:04,031
three weeks there was only one mouse left

93
00:05:04,031 --> 00:05:05,331
in the rock group

94
00:05:05,331 --> 00:05:06,361
* crowd is laughing

95
00:05:06,361 --> 00:05:09,441
It was rather interesting because

96
00:05:09,441 --> 00:05:12,351
the mice they just they seem to be

97
00:05:12,351 --> 00:05:14,267
so disconent with one another and

98
00:05:14,267 --> 00:05:16,787
they would separate themselves from the

99
00:05:16,787 --> 00:05:19,877
other mice and then you know they just

100
00:05:19,877 --> 00:05:22,277
turn around and kill one of the other mice

101
00:05:22,277 --> 00:05:24,774
For as the classical mice and controlled mice

102
00:05:24,774 --> 00:05:26,704
they were perfectly fine with one another

103
00:05:26,704 --> 00:05:28,694
They didn't have problems what so ever

104
00:05:28,694 --> 00:05:32,884
it was, it was interesting and so my

105
00:05:32,884 --> 00:05:34,734
after doing this project for my first

106
00:05:34,734 --> 00:05:37,234
year. I had a lot of suggestion and found

107
00:05:37,234 --> 00:05:40,424
out a lot problems with my project

108
00:05:40,424 --> 00:05:43,632
This is a background of the project

109
00:05:43,632 --> 00:05:47,172
which I just described and as I said

110
00:05:47,172 --> 00:05:49,202
there a lot of problem with the project

111
00:05:49,202 --> 00:05:50,172
there weren't enough subject for

112
00:05:50,172 --> 00:05:52,388
statistical analysis. I'm sorry if you

113
00:05:52,388 --> 00:05:56,128
can't see but were try more or less the

114
00:05:56,128 --> 00:05:59,189
uh. Like I said there weren't enough mice

115
00:05:59,189 --> 00:06:01,689
for statistical analysis i only had 18

116
00:06:01,689 --> 00:06:03,209
mice that first year. So the second year

117
00:06:03,209 --> 00:06:07,289
I did my project i had 72 also in the

118
00:06:07,289 --> 00:06:09,319
first year like I said I obtained the mice

119
00:06:09,319 --> 00:06:11,789
From a local pet store and I did know

120
00:06:11,789 --> 00:06:14,759
what their age , their weight uh what

121
00:06:14,759 --> 00:06:17,129
their genetic background was which had.

122
00:06:17,129 --> 00:06:18,799
which could have an affect on the outcome

123
00:06:18,799 --> 00:06:21,289
of the overall project

124
00:06:21,289 --> 00:06:23,549
Their uh their living condition as

125
00:06:23,549 --> 00:06:25,869
I would say was one of the big problems

126
00:06:25,869 --> 00:06:29,629
They were able to interact with another

127
00:06:29,629 --> 00:06:31,493
and they were also given a

128
00:06:31,493 --> 00:06:34,353
very unrealistic music environment

129
00:06:34,353 --> 00:06:36,443
The two variable groups which listen to

130
00:06:36,443 --> 00:06:40,603
music as I said uh were subjective to

131
00:06:40,603 --> 00:06:44,645
their music 24 hours a day at 90 decibels

132
00:06:44,645 --> 00:06:48,561
and that's a little extreme its kinda loud

133
00:06:48,561 --> 00:06:51,541
and its all day long and so i looked

134
00:06:51,541 --> 00:06:53,711
at these problems and I decided that

135
00:06:53,711 --> 00:06:55,341
it needed a lot of work

136
00:06:56,294 --> 00:07:00,654
So what I did um was i obtained

137
00:07:00,654 --> 00:07:03,674
the 72 white male mice I said but this

138
00:07:03,674 --> 00:07:05,874
year I quoted them from

139
00:07:05,874 --> 00:07:07,724
Harland Spray Darley which is a

140
00:07:07,724 --> 00:07:09,574
laboratory which specializes in the use

141
00:07:09,574 --> 00:07:12,004
of animals in uh research each mouse

142
00:07:12,004 --> 00:07:15,044
each is mouse 4 to 5 weeks old

143
00:07:15,044 --> 00:07:19,584
15 to 20 grams in weight and uh

144
00:07:19,584 --> 00:07:21,014
and their all genetically

145
00:07:21,014 --> 00:07:23,303
similar their all out friend mice

146
00:07:23,303 --> 00:07:25,833
when I received the mice I put them

147
00:07:25,833 --> 00:07:28,053
all to separate 5 gallon aquariums

148
00:07:28,053 --> 00:07:31,813
thus eliminating the possibility of

149
00:07:31,813 --> 00:07:34,043
um subject destruction

150
00:07:34,043 --> 00:07:35,770
*crowd is laughing from joke

151
00:07:35,770 --> 00:07:38,390
I, I also gave the each mouse a

152
00:07:38,390 --> 00:07:42,940
ceratin amount of food light and water

153
00:07:42,940 --> 00:07:46,030
The uh receives 12 hours of light and

154
00:07:46,030 --> 00:07:50,220
music this year was kept 10 at hours a day

155
00:07:50,220 --> 00:07:52,700
at 70 decibels which seem a little more

156
00:07:52,700 --> 00:07:56,010
moderate than 24 hours a day at 90 decibels

157
00:07:59,050 --> 00:08:01,110
the uh 72 mice which i had obtained from

158
00:08:01,110 --> 00:08:03,973
Harland Spray Garley i dived into three

159
00:08:03,973 --> 00:08:06,033
different groups again but this year

160
00:08:06,033 --> 00:08:08,343
i had a small variation of that I

161
00:08:08,343 --> 00:08:10,233
had the control group once again which

162
00:08:10,233 --> 00:08:12,133
was suppose to simulate just how

163
00:08:12,133 --> 00:08:14,143
much a regular mouse should learn .

164
00:08:14,143 --> 00:08:16,433
the classical group this year

165
00:08:16,433 --> 00:08:18,743
listen to mozart and i decide on mozart

166
00:08:18,743 --> 00:08:22,613
because through the past year the

167
00:08:22,613 --> 00:08:24,983
research i had done it seem that mozart

168
00:08:24,983 --> 00:08:26,983
was used the most in other studies done

169
00:08:26,983 --> 00:08:29,583
with in music and then I used once again

170
00:08:29,583 --> 00:08:31,453
Used the anthrax Cd or the hard

171
00:08:31,453 --> 00:08:37,463
rock group this is a picture of the

172
00:08:37,463 --> 00:08:41,993
anthrax cd and it was probably the only

173
00:08:41,993 --> 00:08:44,053
side of the cover that I can show was

174
00:08:44,053 --> 00:08:46,803
decent I'm going to play a you a

175
00:08:46,803 --> 00:08:51,753
very short excerpt from the cd um

176
00:08:51,753 --> 00:08:53,313
if i made it lengthy i don't think

177
00:08:53,313 --> 00:08:55,173
anybody would stay

178
00:08:55,173 --> 00:09:06,573
*inaudible speaking from the crowd

179
00:09:06,573 --> 00:09:10,573
*David putting the cd in the cd player

180
00:09:10,573 --> 00:09:21,423
*anthrax is playing

181
00:09:21,423 --> 00:09:25,423
*Crowd Laughs

182
00:09:28,576 --> 00:09:31,426
* David switches to Classical music

183
00:09:31,426 --> 00:09:36,686
*inaudible speaking from david

184
00:10:14,760 --> 00:11:07,370
*Mozart is playing

185
00:11:08,268 --> 00:11:12,268
That was probably much more pleasant

186
00:11:12,621 --> 00:11:14,471
Upon arrival each mouse was

187
00:11:14,471 --> 00:11:17,341
individually weighed in order to make

188
00:11:17,341 --> 00:11:19,431
sure that they were healthy and

189
00:11:19,431 --> 00:11:20,671
throughout the rest of project each

190
00:11:20,671 --> 00:11:22,971
week the mice were weighed

191
00:11:22,971 --> 00:11:24,831
in order to make sure they stayed

192
00:11:24,831 --> 00:11:26,881
within the healrhy growth curve if the

193
00:11:26,881 --> 00:11:29,761
mice were to suddenly drop in weight the

194
00:11:29,761 --> 00:11:31,758
project would have to stop because

195
00:11:31,758 --> 00:11:34,578
the indication of stress or sickness

196
00:11:34,578 --> 00:11:39,568
caused by the music and this graph

197
00:11:39,568 --> 00:11:43,438
gives you a, a color version I guess of

198
00:11:43,438 --> 00:11:46,298
the growth curve of the mice the red

199
00:11:46,298 --> 00:11:49,198
represent the hard rock or heavy metal

200
00:11:49,198 --> 00:11:51,468
the green represent the control and the

201
00:11:51,468 --> 00:11:54,638
blue represent the classical even though

202
00:11:54,638 --> 00:11:57,598
it looks likes the hard rock makes a

203
00:11:57,598 --> 00:12:00,118
drastic change from week 2 to 3

204
00:12:00,118 --> 00:12:05,368
it still remain within the growth

205
00:12:05,368 --> 00:12:07,618
curve what I did was upon arrival

206
00:12:07,618 --> 00:12:08,828
caused I said the mice were

207
00:12:08,828 --> 00:12:10,528
put into their individual cages

208
00:12:10,528 --> 00:12:11,888
and then they were given a one week

209
00:12:11,888 --> 00:12:13,998
period in which to acclimate to their

210
00:12:13,998 --> 00:12:15,968
new environment this allowed the mice to

211
00:12:15,968 --> 00:12:17,048
settle down and get comfortable with

212
00:12:17,048 --> 00:12:20,448
with their, their surrounding after which

213
00:12:20,448 --> 00:12:23,298
their run through a fixed maze three

214
00:12:23,298 --> 00:12:25,698
times in order to get a base starting

215
00:12:25,698 --> 00:12:27,858
time after they run through maze the

216
00:12:27,858 --> 00:12:31,048
first time they were then subjected to

217
00:12:31,048 --> 00:12:35,048
music the following week and then were run

218
00:12:35,048 --> 00:12:37,208
through the maze another, additional

219
00:12:37,208 --> 00:12:38,628
three times. I continued

220
00:12:38,628 --> 00:12:42,508
to play the music for the next

221
00:12:42,508 --> 00:12:44,228
four weeks and randomized through

222
00:12:44,228 --> 00:12:46,078
the maze three times after each week

223
00:12:46,078 --> 00:12:54,018
and by the first week they knew

224
00:12:54,018 --> 00:12:56,948
the maze you know or they sort a got a

225
00:12:56,948 --> 00:12:58,888
feel for it and then second week

226
00:12:58,888 --> 00:13:03,278
and the third week that's a

227
00:13:03,278 --> 00:13:05,158
little picture of the treat they got

228
00:13:05,158 --> 00:13:08,258
at the end and the fourth week

229
00:13:08,258 --> 00:13:10,478
by this time the a control and classical

230
00:13:10,478 --> 00:13:12,328
knew it very well and the hard

231
00:13:12,328 --> 00:13:15,889
rock I'd hate to say but did not.

232
00:13:15,889 --> 00:13:19,309
This gives a, a data table of the

233
00:13:19,309 --> 00:13:21,339
average run time in seconds as

234
00:13:21,339 --> 00:13:23,639
well as the weights in grams the

235
00:13:23,639 --> 00:13:27,009
week one at the top is the

236
00:13:27,009 --> 00:13:28,849
baseline starting time the initial

237
00:13:28,849 --> 00:13:30,809
one before the music had been started

238
00:13:30,809 --> 00:13:32,459
and all three groups started out

239
00:13:32,459 --> 00:13:34,609
pretty close to ten minutes.

240
00:13:34,609 --> 00:13:37,659
Which about 590 seconds then

241
00:13:37,659 --> 00:13:39,049
throughout the course of the week

242
00:13:39,049 --> 00:13:40,269
the control group manage to get

243
00:13:40,269 --> 00:13:42,449
their time down to 307 seconds

244
00:13:42,449 --> 00:13:45,359
which is about and average of 5 minutes.

245
00:13:45,359 --> 00:13:46,769
The classical group manages to get

246
00:13:46,769 --> 00:13:50,309
their time all the way down to 106

247
00:13:50,309 --> 00:13:53,549
seconds which is about a minute 46

248
00:13:53,549 --> 00:13:55,699
so compared to the normal or average

249
00:13:55,699 --> 00:13:57,799
mouse one that listen to classical is

250
00:13:57,799 --> 00:14:01,799
above average . The hard rock mice

251
00:14:02,465 --> 00:14:04,635
increase their time from 10 minutes

252
00:14:04,635 --> 00:14:08,585
to 1825 seconds which is about

253
00:14:08,585 --> 00:14:10,465
30 minutes and started having

254
00:14:10,465 --> 00:14:12,325
problems with this actually

255
00:14:12,325 --> 00:14:14,365
because during, while running the

256
00:14:14,365 --> 00:14:16,185
control and classical while I did

257
00:14:16,185 --> 00:14:18,415
this during uh early part of the school

258
00:14:18,415 --> 00:14:19,745
year school it was fine because it take

259
00:14:19,745 --> 00:14:22,485
me, you know two hours or

260
00:14:22,485 --> 00:14:24,755
sometime to ten minutes you know

261
00:14:24,755 --> 00:14:25,985
half and hour maybe tops doing for

262
00:14:25,985 --> 00:14:28,575
all the mice for the classical but with

263
00:14:28,575 --> 00:14:29,915
the hard rock by the end of the fourth

264
00:14:29,915 --> 00:14:31,645
week it was taking take me 5 and a

265
00:14:31,645 --> 00:14:33,625
half to 6 hours a day to run these

266
00:14:33,625 --> 00:14:39,465
mice and it was, was getting rather

267
00:14:39,465 --> 00:14:40,235
extreme

268
00:14:40,235 --> 00:14:41,595
* crowd laughing

269
00:14:41,595 --> 00:14:45,595
This give a,a graph of the run time

270
00:14:45,889 --> 00:14:47,959
and at the left it shows that all

271
00:14:47,959 --> 00:14:49,529
three groups started pretty much

272
00:14:49,529 --> 00:14:51,069
at the same time. But then by the

273
00:14:51,069 --> 00:14:52,749
time you progress through the week

274
00:14:52,749 --> 00:14:57,339
the classical which is in blue decrease

275
00:14:57,339 --> 00:15:01,829
their time by 8 and a half minutes

276
00:15:01,829 --> 00:15:05,339
which is went up the control went

277
00:15:05,339 --> 00:15:07,979
up slightly or cut off 5 minutes from

278
00:15:07,979 --> 00:15:11,099
their time and the hard rock went

279
00:15:11,099 --> 00:15:14,199
straight for the bottom they added 20

280
00:15:14,211 --> 00:15:15,611
minutes to their time.

281
00:15:19,211 --> 00:15:23,211
This gives a, a delta which is a

282
00:15:23,229 --> 00:15:25,059
difference between weeks and it

283
00:15:25,059 --> 00:15:26,919
just shows how much time they were

284
00:15:26,919 --> 00:15:30,929
able to, able to cut from the previous

285
00:15:30,929 --> 00:15:35,959
week and by week 4 to 1 it show the

286
00:15:35,959 --> 00:15:38,179
number which I had just said that they

287
00:15:38,179 --> 00:15:40,869
control mange to cut off 291 seconds

288
00:15:40,869 --> 00:15:43,569
the classical 503 seconds and hard

289
00:15:43,569 --> 00:15:51,499
rock had added 1256 seconds this give

290
00:15:51,499 --> 00:15:54,889
a delta graph which is the data table

291
00:15:54,889 --> 00:15:57,994
which I showed you but now its in a graph

292
00:15:57,994 --> 00:15:59,534
and actually shows how the

293
00:15:59,534 --> 00:16:02,674
control between week 1 and 2

294
00:16:02,674 --> 00:16:04,824
actually did slightly better than the

295
00:16:04,824 --> 00:16:06,634
classical but then between 2 and 3,

296
00:16:06,634 --> 00:16:09,440
3 and 4 the classical seem to jump far

297
00:16:09,440 --> 00:16:13,820
ahead. This give a overall graph of the

298
00:16:13,820 --> 00:16:16,910
groups and it shows a real vivid picture

299
00:16:16,910 --> 00:16:19,298
of just how drastics changes were between

300
00:16:19,298 --> 00:16:24,998
the groups after accumulating all my data

301
00:16:25,156 --> 00:16:27,446
which was actually 852 bits whereas the

302
00:16:27,446 --> 00:16:31,446
year before as I mention 30 something

303
00:16:32,051 --> 00:16:34,921
after i seen the data i took it to a

304
00:16:35,061 --> 00:16:39,061
statistician whose was Dr. Mike Doveach

305
00:16:39,061 --> 00:16:41,411
assistant professor of Mathematics and

306
00:16:41,411 --> 00:16:44,141
statics at Old Dominion University.

307
00:16:44,141 --> 00:16:46,411
and when I explained my project to him

308
00:16:46,711 --> 00:16:48,621
and gave him the data he decided

309
00:16:48,621 --> 00:16:51,511
to run three different test and he ran a

310
00:16:51,511 --> 00:16:53,271
Manova test which useda a null

311
00:16:53,271 --> 00:16:56,321
hypothesis, Anova test which looks

312
00:16:56,321 --> 00:16:57,711
for statistical difference from week to

313
00:16:57,711 --> 00:16:59,791
week and a Tukey studentized range

314
00:16:59,791 --> 00:17:01,771
test the most importnat of these was the

315
00:17:01,771 --> 00:17:04,201
Tukey studentized range test this looked

316
00:17:04,201 --> 00:17:08,201
for a statistical significance difference

317
00:17:08,201 --> 00:17:10,891
between one groups to see if you know.

318
00:17:10,891 --> 00:17:13,161
If it was important enough to even

319
00:17:13,161 --> 00:17:17,281
notice and a normal statistical,

320
00:17:17,281 --> 00:17:19,601
statistically significant fact would

321
00:17:19,601 --> 00:17:23,241
be to be a P of value of 0.1 and

322
00:17:23,241 --> 00:17:25,561
after accumulating the data and

323
00:17:25,561 --> 00:17:30,071
making the result we found that between

324
00:17:30,071 --> 00:17:32,011
the classical and control this is from

325
00:17:32,011 --> 00:17:36,011
week 4 to 1 there was a P Value of .01

326
00:17:37,750 --> 00:17:40,880
we then ran out the number later and

327
00:17:40,880 --> 00:17:42,820
found out it was even more significant

328
00:17:42,820 --> 00:17:45,200
it went all the way out to P value of .001

329
00:17:47,780 --> 00:17:49,840
The control to hard rock was as well

330
00:17:49,840 --> 00:17:51,050
found to be significant or

331
00:17:51,050 --> 00:17:52,640
statistically significant out of P value

332
00:17:52,640 --> 00:17:56,470
of .01 it was as well, we as well

333
00:17:56,470 --> 00:17:58,560
went further with that and found out that

334
00:17:58,560 --> 00:18:00,010
it statically significant to a P value

335
00:18:00,010 --> 00:18:05,385
of .0001.and the classical to hard

336
00:18:05,385 --> 00:18:07,795
rock was as well statically significant

337
00:18:07,795 --> 00:18:11,175
at a P Value .01 and extened to a P Value

338
00:18:11,175 --> 00:18:16,305
0001. In conclusion I can say that

339
00:18:16,305 --> 00:18:18,585
music does indeed have an effect

340
00:18:18,585 --> 00:18:20,515
on the learning abilities on white male

341
00:18:20,515 --> 00:18:23,135
mice. Classical music has a very

342
00:18:23,135 --> 00:18:25,835
positive effect on the learning abilities

343
00:18:25,835 --> 00:18:27,575
whereas the hard rock music has

344
00:18:27,582 --> 00:18:29,532
a even greater negative effect on the

345
00:18:29,532 --> 00:18:32,592
learning abilities and a side from the

346
00:18:32,592 --> 00:18:34,812
fact which I have been able shown you

347
00:18:34,812 --> 00:18:38,812
today. I can say from my own view

348
00:18:38,812 --> 00:18:40,712
and my own opinion from observing

349
00:18:40,712 --> 00:18:45,972
the mice that its, its seem to be not

350
00:18:45,972 --> 00:18:48,962
only digress their ability to learn but

351
00:18:48,962 --> 00:18:51,494
their ability to cope one with another

352
00:18:51,494 --> 00:18:55,384
and in fact with the mice after the second

353
00:18:55,384 --> 00:18:57,284
year of this doing their project as I

354
00:18:57,284 --> 00:18:58,774
said i had keep them seperate this year

355
00:18:58,774 --> 00:19:00,834
to try to eliminate the fighting after

356
00:19:00,834 --> 00:19:03,074
the project i would take all the mice to a

357
00:19:03,074 --> 00:19:06,024
local pet store to just get rid of them

358
00:19:06,024 --> 00:19:08,564
and give them away and when I did this

359
00:19:08,564 --> 00:19:10,654
with the classical and control mice

360
00:19:10,654 --> 00:19:12,154
I would put them into a or

361
00:19:12,154 --> 00:19:13,894
just one group at a time I'll

362
00:19:13,894 --> 00:19:15,404
put them into two aquariums

363
00:19:15,404 --> 00:19:17,348
and take them away thas 24 mice

364
00:19:17,348 --> 00:19:19,188
in 20 gallons. and I thought that

365
00:19:19,188 --> 00:19:21,198
wasn't that bad and it wasn't for

366
00:19:21,198 --> 00:19:23,568
the classical and control they were fine

367
00:19:23,568 --> 00:19:25,628
with one another .However when I put

368
00:19:25,628 --> 00:19:27,728
the hardrock mice in there and within

369
00:19:27,728 --> 00:19:31,138
an hour they had just begun fighting so

370
00:19:31,138 --> 00:19:33,318
severely that i had to separate all the

371
00:19:33,318 --> 00:19:35,848
mice and gave them about a week just

372
00:19:35,848 --> 00:19:37,988
to you know chill out I guess you can say

373
00:19:37,988 --> 00:19:38,918
<i>crowds laughing</i>

374
00:19:38,918 --> 00:19:41,468
and sorta, sorta of calm down that

375
00:19:41,468 --> 00:19:43,618
because I guess the music

376
00:19:43,618 --> 00:19:45,188
had made them so uptight

377
00:19:45,188 --> 00:19:47,908
and just you know had been putting

378
00:19:47,908 --> 00:19:50,168
these bad messages into them. That they

379
00:19:50,168 --> 00:19:52,288
couldn't handle one another and so I gave

380
00:19:52,288 --> 00:19:54,418
them about a week just to calm down

381
00:19:54,418 --> 00:19:56,498
and settle down and actually play a little

382
00:19:56,498 --> 00:19:57,618
classical music to them and see if it

383
00:19:57,618 --> 00:20:01,298
would reverse the effects so by, after

384
00:20:01,298 --> 00:20:02,888
about a week or so you know i put

385
00:20:02,888 --> 00:20:05,068
them back in and they were still a

386
00:20:05,068 --> 00:20:07,228
little feisty but i magane to get them

387
00:20:07,228 --> 00:20:09,928
to the store in time. It's just it been

388
00:20:09,928 --> 00:20:12,008
an interesting project and i have

389
00:20:12,008 --> 00:20:14,478
enjoyed doing it and enjoyed the

390
00:20:14,478 --> 00:20:16,348
result i have found as well as the

391
00:20:16,348 --> 00:20:18,208
research I've done and its too bad

392
00:20:18,208 --> 00:20:23,508
that its not a subject that is widely i

393
00:20:23,508 --> 00:20:25,658
guess you can say publicized as

394
00:20:25,658 --> 00:20:28,318
it should be because there i found

395
00:20:28,318 --> 00:20:31,808
multiple areas of research which are

396
00:20:31,808 --> 00:20:35,358
extremely significant whether it how

397
00:20:35,358 --> 00:20:37,518
the great effects of classical music on

398
00:20:37,518 --> 00:20:39,558
preschooler learning the ABC's or

399
00:20:39,558 --> 00:20:42,828
something like or whether its you know

400
00:20:42,828 --> 00:20:45,798
just bad the moral of hard rock music and

401
00:20:45,798 --> 00:20:48,648
something interesting is that these mice

402
00:20:48,648 --> 00:20:51,368
could not understand the lyrics but the

403
00:20:51,368 --> 00:20:54,078
music alone was bad enough much less the

404
00:20:54,078 --> 00:20:56,528
lyrics which the people were subjected to

405
00:20:56,528 --> 00:20:58,748
but the mice were not and that's

406
00:20:58,748 --> 00:21:00,538
something that I think is pretty

407
00:21:00,538 --> 00:21:03,248
significant as well.Once again i would

408
00:21:03,248 --> 00:21:05,388
like to thank you for the opportunity

409
00:21:05,388 --> 00:21:07,868
to be here to be able to present this

410
00:21:07,868 --> 00:21:09,218
project to you.

411
00:21:09,218 --> 00:21:10,808
Thank you

412
00:21:10,808 --> 00:21:14,808
