The theory of multiple intelligences was developed in 1983 by Dr. Howard Gardner, professor of education at Harvard University. It suggests that the traditional notion of intelligence, based on I.Q. testing, is far too limited. Instead, Dr. Gardner proposes eight different intelligences to account for a broader range of human potential in children and adults. These intelligences are:
•Linguistic intelligence ("word smart")
•Logical-mathematical intelligence ("number/reasoning smart")
•Spatial intelligence ("picture smart")
•Bodily-Kinesthetic intelligence ("body smart")
•Musical intelligence ("music smart")
•Interpersonal intelligence ("people smart")
•Intrapersonal intelligence ("self smart")
•Naturalist intelligence ("nature smart")
Dr. Gardner says that our schools and culture focus most of their attention on linguistic and logical-mathematical intelligence. We esteem the highly articulate or logical people of our culture. However, Dr. Gardner says that we should also place equal attention on individuals who show gifts in the other intelligences: the artists, architects, musicians, naturalists, designers, dancers, therapists, entrepreneurs, and others who enrich the world in which we live. Unfortunately, many children who have these gifts don’t receive much reinforcement for them in school. Many of these kids, in fact, end up being labeled "learning disabled," "ADD (attention deficit disorder," or simply underachievers, when their unique ways of thinking and learning aren’t addressed by a heavily linguistic or logical-mathematical classroom. The theory of multiple intelligences proposes a major transformation in the way our schools are run. It suggests that teachers be trained to present their lessons in a wide variety of ways using music, cooperative learning, art activities, role play, multimedia, field trips, inner reflection, and much more (see Multiple Intelligences in the Classroom). The good news is that the theory of multiple intelligences has grabbed the attention of many educators around the country, and hundreds of schools are currently using its philosophy to redesign the way it educates children. The bad news is that there are thousands of schools still out there that teach in the same old dull way, through dry lectures, and boring worksheets and textbooks. The challenge is to get this information out to many more teachers, school administrators, and others who work with children, so that each child has the opportunity to learn in ways harmonious with their unique minds (see In Their Own Way).
The theory of multiple intelligences also has strong implications for adult learning and development. Many adults find themselves in jobs that do not make optimal use of their most highly developed intelligences (for example, the highly bodily-kinesthetic individual who is stuck in a linguistic or logical desk-job when he or she would be much happier in a job where they could move around, such as a recreational leader, a forest ranger, or physical therapist). The theory of multiple intelligences gives adults a whole new way to look at their lives, examining potentials that they left behind in their childhood (such as a love for art or drama) but now have the opportunity to develop through courses, hobbies, or other programs of self-development (see 7 Kinds of Smart).
How to Teach or Learn Anything 8 Different Ways
One of the most remarkable features of the theory of multiple intelligences is how it provides eight different potential pathways to learning. If a teacher is having difficulty reaching a student in the more traditional linguistic or logical ways of instruction, the theory of multiple intelligences suggests several other ways in which the material might be presented to facilitate effective learning. Whether you are a kindergarten teacher, a graduate school instructor, or an adult learner seeking better ways of pursuing self-study on any subject of interest, the same basic guidelines apply. Whatever you are teaching or learning, see how you might connect it with
•words (linguistic intelligence)
•numbers or logic (logical-mathematical intelligence)
•pictures (spatial intelligence)
•music (musical intelligence)
•self-reflection (intrapersonal intelligence)
•a physical experience (bodily-kinesthetic intelligence)
•a social experience (interpersonal intelligence), and/or
•an experience in the natural world. (naturalist intelligence)
For example, if you’re teaching or learning about the law of supply and demand in economics, you might read about it (linguistic), study mathematical formulas that express it (logical-mathematical), examine a graphic chart that illustrates the principle (spatial), observe the law in the natural world (naturalist) or in the human world of commerce (interpersonal); examine the law in terms of your own body [e.g. when you supply your body with lots of food, the hunger demand goes down; when there's very little supply, your stomach's demand for food goes way up and you get hungry] (bodily-kinesthetic and intrapersonal); and/or write a song (or find an existing song) that demonstrates the law (perhaps Dylan's "Too Much of Nothing?").
You don’t have to teach or learn something in all eight ways, just see what the possibilities are, and then decide which particular pathways interest you the most, or seem to be the most effective teaching or learning tools. The theory of multiple intelligences is so intriguing because it expands our horizon of available teaching/learning tools beyond the conventional linguistic and logical methods used in most schools (e.g. lecture, textbooks, writing assignments, formulas, etc.). To get started, put the topic of whatever you’re interested in teaching or learning about in the center of a blank sheet of paper, and draw eight straight lines or "spokes" radiating out from this topic. Label each line with a different intelligence. Then start brainstorming ideas for teaching or learning that topic and write down ideas next to each intelligence (this is a spatial-linguistic approach of brainstorming; you might want to do this in other ways as well, using a tape-recorder, having a group brainstorming session, etc.). Have fun!

Testing Autism Drugs in Human Brain Cells
A Method Involving Pluripotent Stem Cells Could Lead to Personalized Treatment of the Disease

Autism is a highly complex disorder affecting one in every 110 children born in the United States. The disease's genetic profile and behavioral symptoms fluctuate widely from case to case, and this variability has frustrated scientists' efforts to identify effective treatments. A new study suggests that autism could eventually be a target for personalized treatment, targeted to a patient's own neurons.
A team from the University of California, San Diego, and the Salk Institute for Biological Studies devised a way to study brain cells from patients with autism, and found a way reverse cellular abnormalities in neurons that have been associated with autism.
The researchers took skin biopsies from patients with a severe form of autism called Rett syndrome, and genetically reprogrammed those cells into pluripotent stem cells. Pluripotent stem cells have the power to differentiate into any kind of cell in the body, depending on environmental cues during early development. The team differentiated the stem cells into fully functioning neurons, and then studied their functioning. They found that neurons derived from patients with Rett syndrome showed certain abnormalities, including markedly smaller cell bodies, dendrite connections, and decreased cell-to-cell communication.
By treating these patient-derived neurons with an experimental drug, the researchers could reverse the cellular abnormalities. The findings, published today in the journal Cell, could give scientists a powerful tool for pinpointing the causes of autism and other brain disorders, and a way to choose targeted treatments.
"It took us two years to finish this project, and personalized medicine might not be that far off," says Carol Marchetto, first author of the paper and a postdoctoral researcher at the Salk Institute. "In the lifetime of a patient, you could go from his skin sample to a reprogrammed cell, to differentiating into a neuron, and find drugs that could be used on that patient."
Rett syndrome, which mostly affects girls, can cause highly impaired social and communication skills, which become apparent soon after a child learns to walk and talk. Patients with Rett can experience increased difficulty breathing and controlling their movements, and can develop repetitive and compulsive behaviors similar to other forms of autism.
Marchetto sees Rett syndrome as a gateway to the broader study of autism, since many other forms of autism share behavioral and genetic similarities with Rett syndrome.
Most cases of autism seem to stem from a combination of genetic abnormalities, but Rett arises from a single gene mutation, found on the MeCP2 gene on the X chromosome. In girls, one of two X chromosomes carries the mutation, and during fetal brain development, one chromosome is activated within each brain cell, seemingly at random. Rett patients can exhibit varying percentages of brain cells carrying the mutation, which can manifest as varying levels of severity of the disorder.
To understand how this genetic mutation plays out at a cellular level, Marchetto and her colleague Alysson Muotri, an assistant professor in the department of Molecular and Cellular Medicine at the UCSD's School of Medicine, took skin biopsies from four patients with Rett syndrome, reprogrammed them into pluripotent stem cells and experimented with a number of different conditions before they found a combination of growth factors that differentiated the stem cells into functioning human neurons.
They saw that each patient-derived stem-cell line generated a different percentage of neurons carrying the gene mutation. The defective neurons looked and acted differently from their normal counterparts, exhibiting smaller cell bodies, less dendrite connections, and impaired cell-to-cell communication.
The researchers treated neuron cultures with insulin-like growth factor (iGF1), which has been shown to reverse behavioral symptoms of Rett in mice. The drug reversed the biological symptoms of the disorder in the neurons, restoring dendrite connections and cell-to-cell signaling in defective neurons. The researchers plan to use the same process to generate neurons from more patients with both Rett syndrome and other forms of autism.
Jeffrey Neul, assistant professor of molecular and human genetics at Baylor College of Medicine, who studies Rett syndrome in mice, says animal models allow scientists to observe the behavioral effects of the disease, but this is a time- and labor-intensive process.
"The field really has been in desperate need of cellular-based assays that can be used to test therapeutic compounds," says Neul. "And it's really hard to push drug discovery if you don't have something you can do in a more rapid fashion."
The process Marchetto and Muotri have developed takes three months to generate fully functioning human neurons. While this is similar to the time frame of normal brain development, the researchers are looking for ways to speed the process up so they can rapidly generate brain cells and expose them to a variety of molecular factors and drug compounds.
The team also plans to move beyond the Petri dish once they've differentiated neurons from human skin cells, to see how the neurons work in a living brain. "What we can do is transplant human neurons in mouse brains and generate chimeric [hybrid human-animal] models," says Muotri. "We can then expose these animals to different environments, and see how they will affect the human neuron."
James Ellis, professor of molecular genetics at the University of Toronto, is doing similar work in reprogramming patients' skin cells into brain cells. He says that Muotri and Marchetto's findings open up a new testing ground for autism and other neurological disorders. "That's clearly what's going to be required of autism, where different people are going to have different mutations and mechanisms, in how they ended up with that outcome," he says.

Cytomegalovirus Tied to Hearing Loss in Kids
CalorieLab Lab Notes
Cytomegalovirus (CMV), a common virus that usually does not make most people sick, may be associated with hearing loss in kids if mom is infected while pregnant according to a new study. In this study, 354 kids who were 4 years of age and up who had been tested for CMV and had hearing loss were examined. Thirty-four contracted CMV from their mothers and it was observed that kids who were CMV-positive at birth had more severe hearing loss than kids who were not and were more likely to have hearing loss in only one ear. Researchers did not have any clear answers as to why contracting CMV in utero may cause hearing problems. CMV is known to cause serious problems in babies if the mother contracts it during pregnancy. The next step will be to investigate how CMV causes hearing loss.
