We often hear (gladly!) how teachers use our blog articles and brain teasers in their classes. We also hear how many psychology and biology teachers are getting their students excited about brain research, and, to contribute to their efforts, we like to recognize some great initiatives.
Last year, Jeffrey Gonce, a Psychology teacher at Red Land High School (West Shore School District, PA) asked his students to “complete a project describing a recent brain (or genetic) study that affects behavior.” The students could opt to post their articles online, and Jeffrey was kind enough to send us a link to read the results. We enjoyed reading them all, and published in our blog this beautiful essay, titled “Tis better to give than receive”, written by Alexandra, which was subsequently included in a number of neuroscience an psychology blogs.
This year, Jeffrey also sent us his students’ essays, and we are going to recognize and publish this great essay by high school student Megan. Enjoy!
It has long been the source of scientific debate as to whether music can improve the cognitive processes in children. Referred to by some as “The Mozart Effect,” a strong correlation is often found between music and increased brain activity. A new study by Canadian scientists has helped to strengthen that link. It shows that participation in music lessons at an early stage in life can help to improve a child’s memory and learning ability by encouraging different patterns of brain development (Music Training Boosts the Brain, 1).
In this new study, twelve children aged four to six were placed in either an experimental or a control group. The six children in the experimental group attended a Suzuki music school, which teaches children to listen to and imitate music before they attempt to read it (1). The six children in the control group took no music lessons. Over the span of a year, the children in the Suzuki classes were found to perform better on tests assessing memory and general intelligence skills such as literacy and math than the children in the control group. These six children also were found to have more changes in their brains’ responses to sounds than the control group in as little as four months (1).
The technique used to measure this changing brain activity is called magnetoencephalography, or MEG. MEG measures “magnetic fields generated by small intracellular electrical currents in neurons of the brain” (Magneto encephalography, 1).
Music recognition is distributed widely throughout the brain (Ratey, 265). The left hemisphere targets succession of sounds and rhythm, while the right hemisphere contains many other, more specific music areas (97, 265). People who learn to play an instrument, or even to sing, exercise strong connections between these two hemispheres. The creative patternings of the right hemisphere must be joined with action and language motor functions coordinated by the left hemisphere in order for a person to be able to communicate the music from their minds to others in an understandable medium (205).
This “mental exercise” increases cognitive capacity and trains the brain to be better organized. Unlike in some other activities, music exercises the entire brain, which causes other cognitive signals to fly faster and read more accurately (205). This means that people who study music are able to think more quickly and accurately. The motor functions used in music are linked with music because they both are coordinated in the frontal lobe, a portion of the brain mostly devoted to personality and complex thought (205). This means that by increasing one’s musical capacity, one is also increasing his or her memory capacity.
Some obvious evidence of music’s effects on the brain can be demonstrated by the fact that students who have studied music actually score higher on college entrance exams those who haven’t. According to a recent study conducted by the College Board, which administers the Scholastic Assessment Test, or SAT, students who said they had taken music lessons before taking the SAT scored, on average, 51 points higher on the verbal portion of the test and 39 points higher on the math portion than those who didn’t (Marshall, 1). While many scientists believe that much of the evidence found in studies such as these is largely coincidental, with each additional study, the evidence is becoming more convincing. Participation in music lessons at an early stage in life can help to improve a child’s memory and learning ability by encouraging different patterns of brain development. By exercising the brain, children begin to make a better future for themselves at an increasingly earlier age. In addition to further tests on children, psychologists are also now beginning to experiment on the effects of music training on adult minds.

Thank you, Megan, and all other students involved!
