WEBVTT

00:00:09.039 --> 00:00:11.529
David Merell whose is a student

00:00:12.329 --> 00:00:15.549
In Virginia and he did a experiment

00:00:15.873 --> 00:00:18.183
we did an experiment and I just called it

00:00:18.306 --> 00:00:22.566
in my own notes the destructive effect

00:00:22.566 --> 00:00:25.696
of rock and the salutary of effect

00:00:25.696 --> 00:00:28.176
of classical music and i think i will

00:00:28.176 --> 00:00:30.496
just have David come up and explain to

00:00:30.496 --> 00:00:32.926
you what he did and what his experiment

00:00:32.926 --> 00:00:34.736
was and what it demonstrated

00:00:35.024 --> 00:00:39.024
So David

00:01:15.760 --> 00:01:17.430
David: Good Morning

00:01:17.683 --> 00:01:19.313
First of all I Just like to say

00:01:19.363 --> 00:01:21.823
thank you to Mrs. Ogdmen for inviting me

00:01:21.845 --> 00:01:23.875
here to be able to speak to you this

00:01:23.876 --> 00:01:29.886
morning and I would like to um say thank

00:01:29.886 --> 00:01:31.836
you for the wonderful introduction as

00:01:31.836 --> 00:01:34.026
he said my name is David Merell I'm a

00:01:34.026 --> 00:01:36.156
Junior or senior at Nansemond River

00:01:36.156 --> 00:01:38.176
High school and i received a lot of

00:01:38.186 --> 00:01:40.936
recognition for this project which I'm

00:01:40.936 --> 00:01:45.266
here today to tell you about

00:01:45.266 --> 00:01:48.313
I Guess i can start off by

00:01:48.313 --> 00:02:00.793
*inaudible Speaking from the crowd

00:02:00.793 --> 00:02:04.423
David : Hows that Is that, is that better

00:02:04.423 --> 00:02:08.003
Okay Alright As i said my name is

00:02:08.003 --> 00:02:10.813
David Merrel and I' here to tell you about

00:02:10.813 --> 00:02:13.023
an experiment that i received a lot of

00:02:13.023 --> 00:02:17.193
recognition for. I have been brought up

00:02:17.193 --> 00:02:19.093
In my family and my family has been

00:02:19.093 --> 00:02:22.343
big on music they, they seen, what

00:02:22.343 --> 00:02:24.633
you know the big effect that music can

00:02:24.633 --> 00:02:26.943
have on the use of today and on society.

00:02:27.736 --> 00:02:29.886
and they always brought me up teaching me

00:02:29.886 --> 00:02:33.806
that heavy metal that sort of music

00:02:33.806 --> 00:02:36.086
really isn't good for ya and that

00:02:36.088 --> 00:02:39.478
classical music is something that is good

00:02:39.478 --> 00:02:42.068
There's nothing bad about it and just to

00:02:42.068 --> 00:02:44.238
In general realize just how powerful

00:02:44.238 --> 00:02:46.528
music is and I have been doing research

00:02:46.565 --> 00:02:48.915
and our family is , you know has books

00:02:48.931 --> 00:02:51.521
and things like that about music

00:02:51.521 --> 00:02:53.971
and one day we came across this research

00:02:53.971 --> 00:02:56.411
that Michael Bowlen about how he used

00:02:56.411 --> 00:03:01.561
music he used classical music and atonal

00:03:01.583 --> 00:03:04.523
sounds on groups of mice and ran them

00:03:04.523 --> 00:03:07.393
through a maze to see what, what the

00:03:07.403 --> 00:03:08.783
effects would have on them and I said

00:03:08.783 --> 00:03:11.919
that pretty neat, so I came up with a

00:03:11.919 --> 00:03:14.339
project or devised a project that would

00:03:14.339 --> 00:03:17.269
somewhat simulate a learning environment

00:03:17.839 --> 00:03:20.689
for mice for what I did or the title of

00:03:20.689 --> 00:03:22.909
the project is music mice amazes the

00:03:22.909 --> 00:03:24.349
classic rock is growing that continues

00:03:24.349 --> 00:03:26.759
this is a, this actually second year that

00:03:26.759 --> 00:03:30.179
i have done this project

00:03:30.179 --> 00:03:32.909
in this project my hypothesis was that.

00:03:33.416 --> 00:03:35.126
Music would have an effect on the

00:03:35.126 --> 00:03:37.131
learning abilities of white male mice

00:03:37.131 --> 00:03:39.301
classical music will have a positive

00:03:39.301 --> 00:03:41.941
effect whereas hardrock music will have

00:03:41.941 --> 00:03:44.901
a negative effect and as I said this is

00:03:44.901 --> 00:03:47.721
Second year I've done this project and the 1st year.

00:03:47.721 --> 00:03:49.911
I did this project I obtained eighteen

00:03:49.911 --> 00:03:52.401
white male mice from a local pet store.

00:03:52.802 --> 00:03:54.682
and divided them into three different

00:03:54.682 --> 00:03:57.172
groups. A hardrock group or heavy metal

00:03:57.172 --> 00:03:59.502
group which would listen to Anthrax,

00:03:59.502 --> 00:04:03.732
stunt 442 and at the time since we really

00:04:03.732 --> 00:04:06.322
didnt know any good heavy metal groups we

00:04:06.322 --> 00:04:08.312
just went to K-Mart and ask the clerk

00:04:08.312 --> 00:04:10.472
behind the desk whats a good heavy metal

00:04:10.472 --> 00:04:12.862
group and she handed us this CD and after

00:04:12.862 --> 00:04:15.052
about ten seconds of listening to it

00:04:15.052 --> 00:04:16.922
we found that's the one wanted

00:04:16.922 --> 00:04:18.952
*crowd is laughing from David joke

00:04:18.952 --> 00:04:22.704
Um we then ah, we also had a classical

00:04:22.704 --> 00:04:27.094
group. Which we played a variety of different classical

00:04:27.094 --> 00:04:28.734
songs to it, it didn't matter which ones

00:04:28.734 --> 00:04:31.194
as long as it was classical. So we divided

00:04:31.194 --> 00:04:33.074
this mice into three different groups

00:04:33.074 --> 00:04:34.834
and we began running them through a fixed

00:04:34.834 --> 00:04:38.014
maze over the course of the next four weeks

00:04:38.014 --> 00:04:40.926
and as time progressed the mice either

00:04:40.926 --> 00:04:44.936
got faster or slower and ah the classical

00:04:45.010 --> 00:04:47.790
or I'll go into that later. But

00:04:47.790 --> 00:04:49.161
the interesting thing about first year

00:04:49.161 --> 00:04:51.201
I did this project is that actually I

00:04:51.201 --> 00:04:53.611
had to cut it short because the heavy

00:04:53.611 --> 00:04:56.481
music had made these mice who can't

00:04:56.481 --> 00:04:59.291
understand words just the sounds alone

00:04:59.291 --> 00:05:01.851
had made them so violent that within

00:05:01.851 --> 00:05:04.031
three weeks there was only one mouse left

00:05:04.031 --> 00:05:05.331
in the rock group

00:05:05.331 --> 00:05:06.361
* crowd is laughing

00:05:06.361 --> 00:05:09.441
It was rather interesting because

00:05:09.441 --> 00:05:12.351
the mice they just they seem to be

00:05:12.351 --> 00:05:14.267
so disconent with one another and

00:05:14.267 --> 00:05:16.787
they would separate themselves from the

00:05:16.787 --> 00:05:19.877
other mice and then you know they just

00:05:19.877 --> 00:05:22.277
turn around and kill one of the other mice

00:05:22.277 --> 00:05:24.774
For as the classical mice and controlled mice

00:05:24.774 --> 00:05:26.704
they were perfectly fine with one another

00:05:26.704 --> 00:05:28.694
They didn't have problems what so ever

00:05:28.694 --> 00:05:32.884
it was, it was interesting and so my

00:05:32.884 --> 00:05:34.734
after doing this project for my first

00:05:34.734 --> 00:05:37.234
year. I had a lot of suggestion and found

00:05:37.234 --> 00:05:40.424
out a lot problems with my project

00:05:40.424 --> 00:05:43.632
This is a background of the project

00:05:43.632 --> 00:05:47.172
which I just described and as I said

00:05:47.172 --> 00:05:49.202
there a lot of problem with the project

00:05:49.202 --> 00:05:50.172
there weren't enough subject for

00:05:50.172 --> 00:05:52.388
statistical analysis. I'm sorry if you

00:05:52.388 --> 00:05:56.128
can't see but were try more or less the

00:05:56.128 --> 00:05:59.189
uh. Like I said there weren't enough mice

00:05:59.189 --> 00:06:01.689
for statistical analysis i only had 18

00:06:01.689 --> 00:06:03.209
mice that first year. So the second year

00:06:03.209 --> 00:06:07.289
I did my project i had 72 also in the

00:06:07.289 --> 00:06:09.319
first year like I said I obtained the mice

00:06:09.319 --> 00:06:11.789
From a local pet store and I did know

00:06:11.789 --> 00:06:14.759
what their age , their weight uh what

00:06:14.759 --> 00:06:17.129
their genetic background was which had.

00:06:17.129 --> 00:06:18.799
which could have an affect on the outcome

00:06:18.799 --> 00:06:21.289
of the overall project

00:06:21.289 --> 00:06:23.549
Their uh their living condition as

00:06:23.549 --> 00:06:25.869
I would say was one of the big problems

00:06:25.869 --> 00:06:29.629
They were able to interact with another

00:06:29.629 --> 00:06:31.493
and they were also given a

00:06:31.493 --> 00:06:34.353
very unrealistic music environment

00:06:34.353 --> 00:06:36.443
The two variable groups which listen to

00:06:36.443 --> 00:06:40.603
music as I said uh were subjective to

00:06:40.603 --> 00:06:44.645
their music 24 hours a day at 90 decibels

00:06:44.645 --> 00:06:48.561
and that's a little extreme its kinda loud

00:06:48.561 --> 00:06:51.541
and its all day long and so i looked

00:06:51.541 --> 00:06:53.711
at these problems and I decided that

00:06:53.711 --> 00:06:55.341
it needed a lot of work

00:06:56.294 --> 00:07:00.654
So what I did um was i obtained

00:07:00.654 --> 00:07:03.674
the 72 white male mice I said but this

00:07:03.674 --> 00:07:05.874
year I quoted them from

00:07:05.874 --> 00:07:07.724
Harland Spray Darley which is a

00:07:07.724 --> 00:07:09.574
laboratory which specializes in the use

00:07:09.574 --> 00:07:12.004
of animals in uh research each mouse

00:07:12.004 --> 00:07:15.044
each is mouse 4 to 5 weeks old

00:07:15.044 --> 00:07:19.584
15 to 20 grams in weight and uh

00:07:19.584 --> 00:07:21.014
and their all genetically

00:07:21.014 --> 00:07:23.303
similar their all out friend mice

00:07:23.303 --> 00:07:25.833
when I received the mice I put them

00:07:25.833 --> 00:07:28.053
all to separate 5 gallon aquariums

00:07:28.053 --> 00:07:31.813
thus eliminating the possibility of

00:07:31.813 --> 00:07:34.043
um subject destruction

00:07:34.043 --> 00:07:35.770
*crowd is laughing from joke

00:07:35.770 --> 00:07:38.390
I, I also gave the each mouse a

00:07:38.390 --> 00:07:42.940
ceratin amount of food light and water

00:07:42.940 --> 00:07:46.030
The uh receives 12 hours of light and

00:07:46.030 --> 00:07:50.220
music this year was kept 10 at hours a day

00:07:50.220 --> 00:07:52.700
at 70 decibels which seem a little more

00:07:52.700 --> 00:07:56.010
moderate than 24 hours a day at 90 decibels

00:07:59.050 --> 00:08:01.110
the uh 72 mice which i had obtained from

00:08:01.110 --> 00:08:03.973
Harland Spray Garley i dived into three

00:08:03.973 --> 00:08:06.033
different groups again but this year

00:08:06.033 --> 00:08:08.343
i had a small variation of that I

00:08:08.343 --> 00:08:10.233
had the control group once again which

00:08:10.233 --> 00:08:12.133
was suppose to simulate just how

00:08:12.133 --> 00:08:14.143
much a regular mouse should learn .

00:08:14.143 --> 00:08:16.433
the classical group this year

00:08:16.433 --> 00:08:18.743
listen to mozart and i decide on mozart

00:08:18.743 --> 00:08:22.613
because through the past year the

00:08:22.613 --> 00:08:24.983
research i had done it seem that mozart

00:08:24.983 --> 00:08:26.983
was used the most in other studies done

00:08:26.983 --> 00:08:29.583
with in music and then I used once again

00:08:29.583 --> 00:08:31.453
Used the anthrax Cd or the hard

00:08:31.453 --> 00:08:37.463
rock group this is a picture of the

00:08:37.463 --> 00:08:41.993
anthrax cd and it was probably the only

00:08:41.993 --> 00:08:44.053
side of the cover that I can show was

00:08:44.053 --> 00:08:46.803
decent I'm going to play a you a

00:08:46.803 --> 00:08:51.753
very short excerpt from the cd um

00:08:51.753 --> 00:08:53.313
if i made it lengthy i don't think

00:08:53.313 --> 00:08:55.173
anybody would stay

00:08:55.173 --> 00:09:06.573
*inaudible speaking from the crowd

00:09:06.573 --> 00:09:10.573
*David putting the cd in the cd player

00:09:10.573 --> 00:09:21.423
*anthrax is playing

00:09:21.423 --> 00:09:25.423
*Crowd Laughs

00:09:28.576 --> 00:09:31.426
* David switches to Classical music

00:09:31.426 --> 00:09:36.686
*inaudible speaking from david

00:10:14.760 --> 00:11:07.370
*Mozart is playing

00:11:08.268 --> 00:11:12.268
That was probably much more pleasant

00:11:12.621 --> 00:11:14.471
Upon arrival each mouse was

00:11:14.471 --> 00:11:17.341
individually weighed in order to make

00:11:17.341 --> 00:11:19.431
sure that they were healthy and

00:11:19.431 --> 00:11:20.671
throughout the rest of project each

00:11:20.671 --> 00:11:22.971
week the mice were weighed

00:11:22.971 --> 00:11:24.831
in order to make sure they stayed

00:11:24.831 --> 00:11:26.881
within the healrhy growth curve if the

00:11:26.881 --> 00:11:29.761
mice were to suddenly drop in weight the

00:11:29.761 --> 00:11:31.758
project would have to stop because

00:11:31.758 --> 00:11:34.578
the indication of stress or sickness

00:11:34.578 --> 00:11:39.568
caused by the music and this graph

00:11:39.568 --> 00:11:43.438
gives you a, a color version I guess of

00:11:43.438 --> 00:11:46.298
the growth curve of the mice the red

00:11:46.298 --> 00:11:49.198
represent the hard rock or heavy metal

00:11:49.198 --> 00:11:51.468
the green represent the control and the

00:11:51.468 --> 00:11:54.638
blue represent the classical even though

00:11:54.638 --> 00:11:57.598
it looks likes the hard rock makes a

00:11:57.598 --> 00:12:00.118
drastic change from week 2 to 3

00:12:00.118 --> 00:12:05.368
it still remain within the growth

00:12:05.368 --> 00:12:07.618
curve what I did was upon arrival

00:12:07.618 --> 00:12:08.828
caused I said the mice were

00:12:08.828 --> 00:12:10.528
put into their individual cages

00:12:10.528 --> 00:12:11.888
and then they were given a one week

00:12:11.888 --> 00:12:13.998
period in which to acclimate to their

00:12:13.998 --> 00:12:15.968
new environment this allowed the mice to

00:12:15.968 --> 00:12:17.048
settle down and get comfortable with

00:12:17.048 --> 00:12:20.448
with their, their surrounding after which

00:12:20.448 --> 00:12:23.298
their run through a fixed maze three

00:12:23.298 --> 00:12:25.698
times in order to get a base starting

00:12:25.698 --> 00:12:27.858
time after they run through maze the

00:12:27.858 --> 00:12:31.048
first time they were then subjected to

00:12:31.048 --> 00:12:35.048
music the following week and then were run

00:12:35.048 --> 00:12:37.208
through the maze another, additional

00:12:37.208 --> 00:12:38.628
three times. I continued

00:12:38.628 --> 00:12:42.508
to play the music for the next

00:12:42.508 --> 00:12:44.228
four weeks and randomized through

00:12:44.228 --> 00:12:46.078
the maze three times after each week

00:12:46.078 --> 00:12:54.018
and by the first week they knew

00:12:54.018 --> 00:12:56.948
the maze you know or they sort a got a

00:12:56.948 --> 00:12:58.888
feel for it and then second week

00:12:58.888 --> 00:13:03.278
and the third week that's a

00:13:03.278 --> 00:13:05.158
little picture of the treat they got

00:13:05.158 --> 00:13:08.258
at the end and the fourth week

00:13:08.258 --> 00:13:10.478
by this time the a control and classical

00:13:10.478 --> 00:13:12.328
knew it very well and the hard

00:13:12.328 --> 00:13:15.889
rock I'd hate to say but did not.

00:13:15.889 --> 00:13:19.309
This gives a, a data table of the

00:13:19.309 --> 00:13:21.339
average run time in seconds as

00:13:21.339 --> 00:13:23.639
well as the weights in grams the

00:13:23.639 --> 00:13:27.009
week one at the top is the

00:13:27.009 --> 00:13:28.849
baseline starting time the initial

00:13:28.849 --> 00:13:30.809
one before the music had been started

00:13:30.809 --> 00:13:32.459
and all three groups started out

00:13:32.459 --> 00:13:34.609
pretty close to ten minutes.

00:13:34.609 --> 00:13:37.659
Which about 590 seconds then

00:13:37.659 --> 00:13:39.049
throughout the course of the week

00:13:39.049 --> 00:13:40.269
the control group manage to get

00:13:40.269 --> 00:13:42.449
their time down to 307 seconds

00:13:42.449 --> 00:13:45.359
which is about and average of 5 minutes.

00:13:45.359 --> 00:13:46.769
The classical group manages to get

00:13:46.769 --> 00:13:50.309
their time all the way down to 106

00:13:50.309 --> 00:13:53.549
seconds which is about a minute 46

00:13:53.549 --> 00:13:55.699
so compared to the normal or average

00:13:55.699 --> 00:13:57.799
mouse one that listen to classical is

00:13:57.799 --> 00:14:01.799
above average . The hard rock mice

00:14:02.465 --> 00:14:04.635
increase their time from 10 minutes

00:14:04.635 --> 00:14:08.585
to 1825 seconds which is about

00:14:08.585 --> 00:14:10.465
30 minutes and started having

00:14:10.465 --> 00:14:12.325
problems with this actually

00:14:12.325 --> 00:14:14.365
because during, while running the

00:14:14.365 --> 00:14:16.185
control and classical while I did

00:14:16.185 --> 00:14:18.415
this during uh early part of the school

00:14:18.415 --> 00:14:19.745
year school it was fine because it take

00:14:19.745 --> 00:14:22.485
me, you know two hours or

00:14:22.485 --> 00:14:24.755
sometime to ten minutes you know

00:14:24.755 --> 00:14:25.985
half and hour maybe tops doing for

00:14:25.985 --> 00:14:28.575
all the mice for the classical but with

00:14:28.575 --> 00:14:29.915
the hard rock by the end of the fourth

00:14:29.915 --> 00:14:31.645
week it was taking take me 5 and a

00:14:31.645 --> 00:14:33.625
half to 6 hours a day to run these

00:14:33.625 --> 00:14:39.465
mice and it was, was getting rather

00:14:39.465 --> 00:14:40.235
extreme

00:14:40.235 --> 00:14:41.595
* crowd laughing

00:14:41.595 --> 00:14:45.595
This give a,a graph of the run time

00:14:45.889 --> 00:14:47.959
and at the left it shows that all

00:14:47.959 --> 00:14:49.529
three groups started pretty much

00:14:49.529 --> 00:14:51.069
at the same time. But then by the

00:14:51.069 --> 00:14:52.749
time you progress through the week

00:14:52.749 --> 00:14:57.339
the classical which is in blue decrease

00:14:57.339 --> 00:15:01.829
their time by 8 and a half minutes

00:15:01.829 --> 00:15:05.339
which is went up the control went

00:15:05.339 --> 00:15:07.979
up slightly or cut off 5 minutes from

00:15:07.979 --> 00:15:11.099
their time and the hard rock went

00:15:11.099 --> 00:15:14.199
straight for the bottom they added 20

00:15:14.211 --> 00:15:15.611
minutes to their time.

00:15:19.211 --> 00:15:23.211
This gives a, a delta which is a

00:15:23.229 --> 00:15:25.059
difference between weeks and it

00:15:25.059 --> 00:15:26.919
just shows how much time they were

00:15:26.919 --> 00:15:30.929
able to, able to cut from the previous

00:15:30.929 --> 00:15:35.959
week and by week 4 to 1 it show the

00:15:35.959 --> 00:15:38.179
number which I had just said that they

00:15:38.179 --> 00:15:40.869
control mange to cut off 291 seconds

00:15:40.869 --> 00:15:43.569
the classical 503 seconds and hard

00:15:43.569 --> 00:15:51.499
rock had added 1256 seconds this give

00:15:51.499 --> 00:15:54.889
a delta graph which is the data table

00:15:54.889 --> 00:15:57.994
which I showed you but now its in a graph

00:15:57.994 --> 00:15:59.534
and actually shows how the

00:15:59.534 --> 00:16:02.674
control between week 1 and 2

00:16:02.674 --> 00:16:04.824
actually did slightly better than the

00:16:04.824 --> 00:16:06.634
classical but then between 2 and 3,

00:16:06.634 --> 00:16:09.440
3 and 4 the classical seem to jump far

00:16:09.440 --> 00:16:13.820
ahead. This give a overall graph of the

00:16:13.820 --> 00:16:16.910
groups and it shows a real vivid picture

00:16:16.910 --> 00:16:19.298
of just how drastics changes were between

00:16:19.298 --> 00:16:24.998
the groups after accumulating all my data

00:16:25.156 --> 00:16:27.446
which was actually 852 bits whereas the

00:16:27.446 --> 00:16:31.446
year before as I mention 30 something

00:16:32.051 --> 00:16:34.921
after i seen the data i took it to a

00:16:35.061 --> 00:16:39.061
statistician whose was Dr. Mike Doveach

00:16:39.061 --> 00:16:41.411
assistant professor of Mathematics and

00:16:41.411 --> 00:16:44.141
statics at Old Dominion University.

00:16:44.141 --> 00:16:46.411
and when I explained my project to him

00:16:46.711 --> 00:16:48.621
and gave him the data he decided

00:16:48.621 --> 00:16:51.511
to run three different test and he ran a

00:16:51.511 --> 00:16:53.271
Manova test which useda a null

00:16:53.271 --> 00:16:56.321
hypothesis, Anova test which looks

00:16:56.321 --> 00:16:57.711
for statistical difference from week to

00:16:57.711 --> 00:16:59.791
week and a Tukey studentized range

00:16:59.791 --> 00:17:01.771
test the most importnat of these was the

00:17:01.771 --> 00:17:04.201
Tukey studentized range test this looked

00:17:04.201 --> 00:17:08.201
for a statistical significance difference

00:17:08.201 --> 00:17:10.891
between one groups to see if you know.

00:17:10.891 --> 00:17:13.161
If it was important enough to even

00:17:13.161 --> 00:17:17.281
notice and a normal statistical,

00:17:17.281 --> 00:17:19.601
statistically significant fact would

00:17:19.601 --> 00:17:23.241
be to be a P of value of 0.1 and

00:17:23.241 --> 00:17:25.561
after accumulating the data and

00:17:25.561 --> 00:17:30.071
making the result we found that between

00:17:30.071 --> 00:17:32.011
the classical and control this is from

00:17:32.011 --> 00:17:36.011
week 4 to 1 there was a P Value of .01

00:17:37.750 --> 00:17:40.880
we then ran out the number later and

00:17:40.880 --> 00:17:42.820
found out it was even more significant

00:17:42.820 --> 00:17:45.200
it went all the way out to P value of .001

00:17:47.780 --> 00:17:49.840
The control to hard rock was as well

00:17:49.840 --> 00:17:51.050
found to be significant or

00:17:51.050 --> 00:17:52.640
statistically significant out of P value

00:17:52.640 --> 00:17:56.470
of .01 it was as well, we as well

00:17:56.470 --> 00:17:58.560
went further with that and found out that

00:17:58.560 --> 00:18:00.010
it statically significant to a P value

00:18:00.010 --> 00:18:05.385
of .0001.and the classical to hard

00:18:05.385 --> 00:18:07.795
rock was as well statically significant

00:18:07.795 --> 00:18:11.175
at a P Value .01 and extened to a P Value

00:18:11.175 --> 00:18:16.305
0001. In conclusion I can say that

00:18:16.305 --> 00:18:18.585
music does indeed have an effect

00:18:18.585 --> 00:18:20.515
on the learning abilities on white male

00:18:20.515 --> 00:18:23.135
mice. Classical music has a very

00:18:23.135 --> 00:18:25.835
positive effect on the learning abilities

00:18:25.835 --> 00:18:27.575
whereas the hard rock music has

00:18:27.582 --> 00:18:29.532
a even greater negative effect on the

00:18:29.532 --> 00:18:32.592
learning abilities and a side from the

00:18:32.592 --> 00:18:34.812
fact which I have been able shown you

00:18:34.812 --> 00:18:38.812
today. I can say from my own view

00:18:38.812 --> 00:18:40.712
and my own opinion from observing

00:18:40.712 --> 00:18:45.972
the mice that its, its seem to be not

00:18:45.972 --> 00:18:48.962
only digress their ability to learn but

00:18:48.962 --> 00:18:51.494
their ability to cope one with another

00:18:51.494 --> 00:18:55.384
and in fact with the mice after the second

00:18:55.384 --> 00:18:57.284
year of this doing their project as I

00:18:57.284 --> 00:18:58.774
said i had keep them seperate this year

00:18:58.774 --> 00:19:00.834
to try to eliminate the fighting after

00:19:00.834 --> 00:19:03.074
the project i would take all the mice to a

00:19:03.074 --> 00:19:06.024
local pet store to just get rid of them

00:19:06.024 --> 00:19:08.564
and give them away and when I did this

00:19:08.564 --> 00:19:10.654
with the classical and control mice

00:19:10.654 --> 00:19:12.154
I would put them into a or

00:19:12.154 --> 00:19:13.894
just one group at a time I'll

00:19:13.894 --> 00:19:15.404
put them into two aquariums

00:19:15.404 --> 00:19:17.348
and take them away thas 24 mice

00:19:17.348 --> 00:19:19.188
in 20 gallons. and I thought that

00:19:19.188 --> 00:19:21.198
wasn't that bad and it wasn't for

00:19:21.198 --> 00:19:23.568
the classical and control they were fine

00:19:23.568 --> 00:19:25.628
with one another .However when I put

00:19:25.628 --> 00:19:27.728
the hardrock mice in there and within

00:19:27.728 --> 00:19:31.138
an hour they had just begun fighting so

00:19:31.138 --> 00:19:33.318
severely that i had to separate all the

00:19:33.318 --> 00:19:35.848
mice and gave them about a week just

00:19:35.848 --> 00:19:37.988
to you know chill out I guess you can say

00:19:37.988 --> 00:19:38.918
<i>crowds laughing</i>

00:19:38.918 --> 00:19:41.468
and sorta, sorta of calm down that

00:19:41.468 --> 00:19:43.618
because I guess the music

00:19:43.618 --> 00:19:45.188
had made them so uptight

00:19:45.188 --> 00:19:47.908
and just you know had been putting

00:19:47.908 --> 00:19:50.168
these bad messages into them. That they

00:19:50.168 --> 00:19:52.288
couldn't handle one another and so I gave

00:19:52.288 --> 00:19:54.418
them about a week just to calm down

00:19:54.418 --> 00:19:56.498
and settle down and actually play a little

00:19:56.498 --> 00:19:57.618
classical music to them and see if it

00:19:57.618 --> 00:20:01.298
would reverse the effects so by, after

00:20:01.298 --> 00:20:02.888
about a week or so you know i put

00:20:02.888 --> 00:20:05.068
them back in and they were still a

00:20:05.068 --> 00:20:07.228
little feisty but i magane to get them

00:20:07.228 --> 00:20:09.928
to the store in time. It's just it been

00:20:09.928 --> 00:20:12.008
an interesting project and i have

00:20:12.008 --> 00:20:14.478
enjoyed doing it and enjoyed the

00:20:14.478 --> 00:20:16.348
result i have found as well as the

00:20:16.348 --> 00:20:18.208
research I've done and its too bad

00:20:18.208 --> 00:20:23.508
that its not a subject that is widely i

00:20:23.508 --> 00:20:25.658
guess you can say publicized as

00:20:25.658 --> 00:20:28.318
it should be because there i found

00:20:28.318 --> 00:20:31.808
multiple areas of research which are

00:20:31.808 --> 00:20:35.358
extremely significant whether it how

00:20:35.358 --> 00:20:37.518
the great effects of classical music on

00:20:37.518 --> 00:20:39.558
preschooler learning the ABC's or

00:20:39.558 --> 00:20:42.828
something like or whether its you know

00:20:42.828 --> 00:20:45.798
just bad the moral of hard rock music and

00:20:45.798 --> 00:20:48.648
something interesting is that these mice

00:20:48.648 --> 00:20:51.368
could not understand the lyrics but the

00:20:51.368 --> 00:20:54.078
music alone was bad enough much less the

00:20:54.078 --> 00:20:56.528
lyrics which the people were subjected to

00:20:56.528 --> 00:20:58.748
but the mice were not and that's

00:20:58.748 --> 00:21:00.538
something that I think is pretty

00:21:00.538 --> 00:21:03.248
significant as well.Once again i would

00:21:03.248 --> 00:21:05.388
like to thank you for the opportunity

00:21:05.388 --> 00:21:07.868
to be here to be able to present this

00:21:07.868 --> 00:21:09.218
project to you.

00:21:09.218 --> 00:21:10.808
Thank you

00:21:10.808 --> 00:21:14.808
