Change Ethnic Poverty

Students of African American and Hispanic background were recently part of a pilot project using a novel system of cognitive assessment to assess children’s learning potential. It was developed by Professor Reuven Feuerstein. The assessment consists of a battery of six to eight tests which measure abstract thinking, analogies, and qualitative thinking and are not culturally-biased.

“Nationally, African American students are identified as educationally mentally retarded twice as often as their white peers; and African Americans are identified as emotionally/behaviorally disordered one and a half times as often as their white peers. The actual number of these “BD” (Behavioral Disorder) diagnoses has increased by 500% between 1974 and 1998.”

Dr. Eric Cooper, President of the National Urban Alliance notes how unfortunate it is that “misdiagnosis of special education status has been used to place a significant number of children of color into programs that doom them to a life of low expectations and low achievement.”

Professor Feuerstein agrees and writes that “Too often we give up on children who are labeled with learning disabilities, but my work has found that using more creative techniques to teach these children will lead them to the same successes that life offers the other children in the classroom. Poverty is not destiny and we can reverse major depression in a child’s cognitive development and realize impressive results.”

Feuerstein’s theory of Structural Cognitive Modifiability “views the human organism as open, adaptive and amenable for change. The aim of this approach is to modify the individual, emphasizing autonomous and self-regulated change. Intelligence is viewed as a propensity of the organism to modify itself when confronted with the need to do so. Intelligence is defined as a changeable state rather than an immutable trait.”

Feuerstein’s claim that “poverty is not destiny” and that we can improve a child’s cognitive development and realize impressive results is profoundly important. He asserts that the benefits to all of society cannot be overstated.

Let me give one example. It has been proposed by Dr. Paul Nussbaum that learning may act as a potential vaccine again Alzheimer’s Disease and other age-related neurodegenerative diseases of the brain.

If we begin to think of learning as a process that improves health, like nutrition and exercise, then all students need to maximize their cognitive development. If tens and hundreds of thousands of poor children are placed in programs that doom them to a life of low expectations and low achievement and learning does act as a vaccine against age-related neurodegenerative diseases of the brain, we are accelerating the rate of dementias.

Childhood poverty has already been linked to dementia. Author of the research, Dr Moceri, said that “a poor quality childhood environment could prevent the brain from reaching a complete level of maturation.” The areas of the brain that show the earliest signs of Alzheimer’s are the one that take the longest time to mature during childhood and adolescence.

There are more than 5 million people in the United States living with Alzheimer’s. This means that every 72 seconds, someone develops Alzheimer’s. The indirect costs of Alzheimer’s and other dementias amount to more than $148 billion annually. Feuerstein’s International Center for the Enhancement of Learning works with children throughout the world. Plans are underway to start implementing the partnership in 20 U.S. cities. Educators, policy makers and journalists should follow the story carefully.

Brains, Music and Learning (Web Weaver Clip Art 2009)

By Amy Price PhD

In 2007 colleagues and I conducted a 42 participant study as part of a research school experiment on working memory and cognitive loading. We explored using music as a strategic intervention to alter working memory loads. The premise was music could aid in more effectual encoding to increase learning potential.  As we learn extraneous or intrinsic cognitive load is invoked. Extraneous working memory loading is experienced by learners as they interact with instructional materials. Intrinsic cognitive load is the inherent level of difficulty associated with instructional materials (Chandler and Sweller 1991). More learning cues such as using pictures as well as words, learning with a song or even allowing student’s hands on instruction helps decrease this load. The more unnecessary information it takes to deliver your point the more extraneous cognitive load is produced. This is where a picture is worth a thousand words!  (Ayres 2006) states that when intrinsic or extraneous cognitive load is high, working memory is overloaded and learning is adversely affected.

This process happens as we learn new skills that we later do with some automaticity such as driving, riding a bike, learning a musical instrument or even doing algebra. The forming of efficient categorization and schemas is called germane load (Paas et al 2003, Sweller et al 1998).  

We considered that since music aids in efficient categorization perhaps learning and music together could decrease cognitive loading and increase germane ability by lightening the load. We tested this by having participants first listen to music designed to entrain concentration. According to (Doman 2007) entrainment can occur in as little as one minute. Music with specific timbres and rhythmic structure has demonstrated an increase in effectual category formation, (Ostrander1994, Rose1997) and can aid visual spatial perception, (Ruvenshteyn and Parrino, 2005) (Orel, 2006) Music is shown to aid in hemispheric transfer or communication between both halves of the brain (Taut et al 2005). We felt participants in the auditory condition would increase germane load and decrease extraneous load. The decrease in extraneous load is expected because of the neuronal changes evoked by entrainment (Pouliot 1998) (Carter and Russel 1992)

 What were our findings? Approximately 50% of our participants immediately increased their ability to sustain cognitive load by 150%. The other 50% decreased in this ability however many of these reported greater clarity of thought later in the day and improved their testing scores considerably. The lesson we learned from this is that for music to be effective at least for ½ the population consistency is the key. Many individuals need a consolidation period where learning is categorized and music is internalized.  

In fact, there are long term benefits of listening to music, notes Dan Levitin in This is Your Brain on Music.

“Music listening enhances or changes certain neural circuits, including the density of dendritic connections in the primary auditory cortex…The front portion of the corpus callosum—the mass of fibers connecting the two cerebral hemispheres—is significantly larger in musicians than non-musicians, and particularly for musicians who began their training early…Musicians tend to have larger cerebellums than non-musicians, and an increased concentration of grey matter…responsible for information processing.” In the end music is like exercise, starting later in life is better than not starting at all and may confer neuroprotective benefits…but that is another study!

Brain, Music and Memory (Dr Janata 2009)

Brain on Music (Dr Janata)

By Amy Price PhD

We have found in our practice that music can trigger powerful memories even for people that have sustained brain damage and have lost the ability to speak. Sometimes stroke or TBI victims can sing fluently because the path to music is stored in a different area of the brain than the one used for recalling words. As a culture we understand the power of music and now a brain-scan study reveals where music makes its mark.
The part of the brain music activates is known as the medial pre-frontal cortex and sits just behind the forehead. “What seems to happen is that a piece of familiar music serves as a soundtrack for a mental movie that starts playing in our head.” said Dr. Janata, a cognitive neuroscientist at University of California, Davis. “It calls back memories of a particular person or place, and you might all of a sudden see that person’s face in your mind’s eye.”
Janata noticed the medial pre-frontal cortex showing the same kind of activity when In Janata’s study this area responded quickly to music rhythm and chord changes, but also reacted when tunes were autobiographically relevant. In addition music provoked the strongest activity in the brain when it was combined with autobiographical memories.

This latest research could explain why even Alzheimer’s patients who endure increasing memory loss can still recall songs from their distant past. It is thought that medial portion of the prefrontal cortex is less susceptible to atrophy according to Janata.
Music does not cure Alzheimer’s or fix TBI but can help patients recover precious memories, help with thought organization and improve quality of life.
Maybe the Apple a day for Alzheimer’s is the IPOD. Dr. Janata has a project underway to make that happen

Dallas Hextell Foundation 2009 for video click Picture

Brain injury, Spinal Cord Damage and Cerebral Palsy are demonstrating success with patients own stem cells. Research for AIDS, MS and Sickle cell using donor cells are increasing. Public and Private cell banking facilities demand a choice, share with others or keep your own for a time of need?

Mary Carmichael of Newsweek did a compelling interview with a couple whose young son was diagnosed with cerebral palsy and the doctor who conducted the experimental treatment. She outlines the medicine for profit aspect of stemcell storage. The pathos of the doctors comments that he may have gotten better anyway and the soft sell for public banking yet raise interesting points. My children are  adults but even in the early years their cord blood was collected and donated for research.

 The Hextell’s featured in the video above tried to conceive for three years and finally with invitro fertilization succeeded. Little Dallas was born wanted and celebrated into a medicine savvy family who banked his own cord blood cells. Dallas was diagnosed with cerebral palsy and became one of the privileged children chosen for research at Duke university. If my children had Cerebral Palsy they could not have enjoyed this benefit because the cells were given for others and presonal access was unavailable.  I would propose a two tier system where cells could be banked for public use but accessed in case of physical need by the donor providing cells were still available.

This is the way we prepared for my husbands bilateral hip replacement. We arranged to have blood taken in advance and then agreed if it was not needed it would go into the public bank. It turns out he needed his blood and then some which made me feel the power of the donations  of all the blood and platelets we have supplied over the years as a family. Some conditions require more cells than the cord blood can grow and others have genetic variables that would make using someone else’s cord cells  more viable.

I am blogging on this because I recieve requests from parents asking if they should take their children to China in hope of a cure.  Research in the USA and from animals studies show about a 30% improvement rate. Opponents and researchers agree that only 1-2% of the cells get to the brain when delivered intravenously, however it may be other components in the cell that are acting to faciliate repair and recovery.  I will blog an answer from my perspective in a future blog

"Junk DNA" Courtesy Crystal Links.com 2009

By Amy Price PhD

Not so many years ago we were told as students that a very small part of the genome coded for genes and the rest was ‘Junk DNA”. The questions why? followed by what if  come quickly when I am faced with such literal statements. The answer they are junk because no one knows what they do brought cause for alarm in my view because I don’t know what a good portion of the human race does  yet I would not relegate them to junk. I countered with I want to know what happened when you took them all out…turns out that was not doable and I was relegated to the divergent thinker category and lectured on the KISS (Keep It Simple Stupid) principle.

I later found a few people such as McClintock who saw this DNA may have value in the 1940s and worked tirelessly  to explore the DNA as a regulatory source for determining which genes are turned on and when they were activated (McClintock, 1965) Around the same time  Britten and  Davidson agreed and further  speculated the junk DNA plays a role in generating different cell types and different biological structures, depending on where in the genome they insert themselves (Britten & Davidson, 1969).

Recently, scientists from Princeton  and Indiana Universities studied the genome of a pond organism and found  that junk DNA or transposons may perform functions that are central to the existence of an organism. Apparently  these genes jump from location to location rearranging  the genome in a way that initiates growth just as McClintock thought. 

These genes are labelled transposons. In and during development, the transposons appear to first influence hundreds of thousands of DNA pieces to regroup. Then, when they are no longer needed the organism can erase the transposases from its genetic material, paring its genome to about 5 percent of its original load.

“The transposons actually perform a central role for the cell,” said Laura Landweber, a professor of ecology and evolutionary biologyat Princeton and an author of the study. “They stitch together the genes in working form.” This research  appeared in the May 15 edition of Science. (MacPherson, Princeton, 2009)

We are just now finding the science that existed in the mind of a researcher over sixty years ago and can watch revelation unravel as  science begins to explore how extensive the role of  junk  or as sometimes coined selfish DNA plays in  the circle of life….Sometimes just as in life it is those quietly working without accolades that are holding it all together who are the real stars!
