This past week in Psychology of Music Learning and Behavior, we touched on an interesting topic I'd never given much thought: cochlear implants. Truthfully, I didn't really know anything about them other than their ability to provide hearing to the deaf. It turns out, though, that the sounds the cochlear implants create do not really recreate the way the natural ear hears sound. She posed an ethical question to us - one for which I have not yet formulated an answer. She asked us if it is ethical for parents to give their young children cochlear implants, fully understanding that their children's sound experience will not be a natural hearing experience and taking into account how well modern society accommodates the deaf. (Talk amongst yourselves).
So, I decided to read some research this week regarding cochlear implants. I found a study which sought to determine the ability of prelingually and congenitally deaf children to recognize popular songs as well as their ability to discriminate pitches. The performed three experiments involving the cochlear implants.
1) They compared the ability of children with cochlear implants and children with normal hearing to recognize popular music,
2) they compared the ability of children with cochlear implants and children with normal hearing to detect changes in pitch, and
3) they compared the ability of children with cochlear implants and children with normal hearing to identify changes in melodic content.
The study found that, across all the experiments, children with cochlear implants performed worse than children with normal hearing. The did determine that children with cochlear implants were able to recognize popular music from the commercial recordings and from instrumental tracks of the tunes and that children with cochlear implants were able to detect changes in pitch as minute as half of a semitone. Children with cochlear implants, however, were not able to detect changes in melodic content in a statistically significant way.
Vongpaisal, T.; Trehub, S. E.; Schellenberg, E. G. (2006). Song recognition by children and adolescents with cochlear implants. Journal of Speech, Language, and Hearing Research, 49, 1092-1103.
The study makes a pretty solid case for the benefits of cochlear implants, as far as pitch recognition goes. But, as for the ethical question posed above, there remains the question, "so what?" Yes, cochlear implants allow the user to discern pitches. But, do children with cochlear implants have affective experiences when exposed to music? Are they able to experience the musical phenomenon or can they just identify its existence?
I am getting more in the habit of asking that question after reading a study: "so what?" That is something my professor is really pushing us to do. Doing so has prompted some interesting research questions of my own. ( I am keeping a list, but I won't post my ideas here lest one of you try to poach them!) I have had a few interesting questions come out of my Child and Adolescent Development class. This week we discussed issues of over scheduling, and unstructured or free play as they pertain to children. We also talked about multiple intelligences and learning types (auditory, visual, kinesthetic). It turns out there is research out there that says these things aren't really things. More to come on this topic. I plan on reading a lot of this research.
Statistics: there is a test this week. Pray for me. Doesn't matter to which god. I will take help from wherever it happens to come.
I learned something very important this week: when they post a sign on the front door of the school that says, "fire drill at 1:30pm on Wednesday," it might be important to put that in your calendar so you don't end up going to the bathroom and have to run out of the building, mid-number 2. Just saying.
The Temple Prep Wind Ensemble is going to be an interesting journey. The problems of my past have followed me to Philly. The students can't read. They are motivated to be there and enjoy playing their instruments, but they have no concept of rhythm. I am trying to figure out how to balance rhythmic instruction with music rehearsal. How much rote teaching am I willing to do? How much theoretical work will end up discouraging the students? I have to keep it fun, but I have to teach them as well. I will let you know next week how I decide to handle this.
On a completely unrelated note, I made hard cider yesterday. My roommate and I went apple picking and I bought freshly-pressed cider. It is happily fermenting in my kitchen. Look at it:
Watch it ferment:
Every bubble is sugars being digested and turned into alcohol and carbon dioxide by the yeast. It should be ready by Thanksgiving. That's right, family, I'm bringing Mitch Cider to Thanksgiving. My OG (original gravity) reading was 1.074, which should get us somewhere around 9.5% or 10% ABV (alcohol by volume).
I did not hurt myself playing flag football today. Yay! And we won! Yay! And the Ravens seem to have stomped on the Panthers! Yay! And the Steelers lost! Yay! It was a good day for football.
That is all for now.
Future Doctor Mitch, out!
