Teach your baby to read - Finally a scientifically based study

Philip Copitch, Ph.D.

Over the last few years, parents have asked me for my professional thoughts on teaching their baby to read. If you do not know what I am talking about, in a nutshell, there is a growing industry of products claiming they will help you teach your baby to read, usually starting at 3 months of age.
Good parenting
Part of being a parent, and especially a new parent, is dealing with that nagging sense, “Am I doing everything for my baby?” None of us want to be just ‘adequate’ at the daunting job of parenting, so it makes sense that we want our baby to have the best we can offer.
So, if you can teach your baby to read by age 9 months, why wait until age 5? In fact, if you wait until age 5, aren’t you really holding your baby back?
It is normal to fear
It is normal to fear making a mistake with our children. It is also normal to want to give our baby the best we can offer.
All this being true, is it appropriate for a product manufacturer to tell us that their product can do a wondrous thing, such as help us start our baby down the path to learning, without proof?
The teach your baby to read companies typically address this concern with “proof” through testimonials. They explain, “hundreds of parents say” or, “We get thank you emails every day” telling us that our flashcards and DVD’s change babies lives.
The testimonials are real, but are they proof that a product teaches a baby to read?
I am a true believer that the responsibility of proof for amazing products falls on the manufacturer to produce, and a testimonial is not proof. A testimonial is the opinion of a mom or a dad who has invested a great deal of time, effort, and love into the teaching project - a project they want to work. We can all be deluded into believing something, it is a common mistake. Just this morning, while I brushed my teeth, I was looking in the mirror and thought, “I’m not too fat…” Whatever that means.
Finally a scientific study
Susan B. Neuman, Professor of Early Childhood and Literacy Education at New York University, Steinhardt School of Culture, Education, and Human Development, and her colleagues, have conducted the first controlled study specifically looking at the effects of a best-selling baby media product on reading development.
The product is intended to be used with infants as young a 3 months old. One hundred and seventeen infants, ages 9 to 18 months, were randomly assigned to treatment (i.e. - did the reading program) and control groups (no reading program).
According to the study, Can Babies Learn to Read? A Randomized Trial of Baby Media, “Children in the treatment condition received the baby media product, which included DVDs, word and picture flashcards, and word books to be used daily over a 7-month period; children in the control condition, business as usual.”
The study was published in the Journal of Educational Psychology, Feb 24 , 2014, See the abstract
According to the study, “[by]examining a 4-phase developmental model of reading, we examined both precursor skills (such as letter name, letter sound knowledge, print awareness, and decoding) and conventional reading (vocabulary and comprehension) using a series of eye-tracking tasks and standardized measures.”
The study found
The study found that the babies did not learn to read. But, and this is a big but, some parents were happy with their baby’s reading skills and confident in the product’s benefit.
In conclusion
This is only one study and in science, replication of a study is important. However, if I wanted to sell a reading program I was sure was the best thing since the Gutenberg press was invented, I would go to three major universities and pay for rigorous science based studies of my product. After the researchers independently found out that I did indeed have a great product, I would email the scientific studies to parents, along with a 20 percent off discount coupon. Then I’d sit back and watch the money roll in knowing that I was helping babies learn to read.

In fact, I wonder why this isn’t the business model that companies use to sell, say… wrinkle reduction creams, weight loss wizardry, or free energy from unicorn tail hairs. If you can prove that your product is great, wouldn’t it be easier to sell it? And if you cannot prove the benefits of your product, it would seem you have to fall back onto testimonials and manipulative wordplay to sell your gadget.

3D image of the most famous brain in neuroscience

Philip Copitch, Ph.D.
The most famous brain in neuroscience belongs to Patient H.M. Don’t worry if you have never heard of Patient H.M., his real name was a medical secret until his death in 2008.
Patient H.M. is famous because of how much his medical condition helped neurologists learn about the inner workings of the human brain. Before Patient H.M., scientists believed that memory was stored throughout the brain. By studying Patient H.M., scientists got their first insight into the evidence that memory was controlled by a small part of the brain called the hippocampi and its attached tissue
Patient H.M.
Patient H.M. was Henry Molaison. All of us owe Mr. Molaison a debt of gratitude. As a child, Mr. Molaison suffered from major epileptic seizures. When epileptic seizures occur lots of neurons in the brain fire all at the same time in an abnormal way. Often seizures occur without warning. They can be mild, with loss of awareness; to severe, with uncontrolled body spasms and loss of consciousness.
Patients with recurring epileptic seizures are often prescribed anti-seizure medication. Mr. Molaison was not helped by this medication. To relieve the severe seizures, Mr. Molaison’s doctor removed the part of Mr. Molaison's brain that was causing the devastating seizures.
Following the surgery, Mr. Molaison’s seizures became manageable, but he no longer possessed short term memory. As the moments of his day went by, Mr. Molaison instantly forgot what he just did. Other parts of his memory were intact, but not his short term memory.
Mr. Molaison allowed himself to be studied by neurologists throughout his life, and after his death he donated his brain for further study. 
3D brain
Mr. Molaison's brain has been studied by many neurologists. In order to provide access to more scientists who wish to study Mr. Molaison’s brain, it has been made into a 3D virtual model.
This 41 second video shows the painstaking slicing of the frozen brain that was done to form the layered images of Mr. Molaison’s brain. This video is not for the squeamish.

Antidepressant drugs and drug-induced liver injury

Philip Copitch, Ph.D.

The American Journal of Psychiatry reports
December 2013, researchers reported in The American Journal of Psychiatry that common antidepressant drugs can cause liver damage in humans. Drug-induced liver injury (DILI) was found in 0.05-3.0% of those taking antidepressants.
The researchers did a PubMed review from 1965 to the present, and reported that all antidepressants can induce hepatotoxicity (liver cell damage or destruction), especially in elderly patients or patients taking multiple prescription medications. This chemically driven cell damage was found to be unrelated to drug dosage and generally occurred between several days and 6 months of starting the medication.

The antidepressants associated with greater risks of damaging the liver are:
  • iproniazid
  • nefazodone
  • phenelzine
  • imipramine
  • amitriptyline
  • duloxetine
  • bupropion
  • trazodone
  • tianeptine
  • agomelatine

The antidepressants that seem to have the least potential  to damage the liver are 
  • citalopram
  • escitalopram
  • paroxetine
  • fluvoxamine

The researchers conclude:
Although an infrequent event, DILI from antidepressant drugs may be irreversible, and clinicians should be aware of it.

Advice for teens - build a life rather than live one

Philip Copitch, Ph.D.

Ashton Kutcher gives great advice
In August 2013, Ashton Kutcher got the “old man’s award” from the Teen Choice Awards. He talked passionately about working towards one’s goals. Watch his 5 minute speech.


When opportunity knocks
Ashton’s speech reminded me of the story of opportunity knocking.
A young man was looking for a way to make money. He didn’t want to just make money; he really wanted a way to make lots of money. He also wanted to feel good about himself as he made his dreams come true.A knock came at the door. The young man opened it to find an older man wearing dirty overalls and work gloves. “I am opportunity,” the older man said. “I came to help you get to your hopes and dreams.”“You don’t look like opportunity,” the young man said. “You’re dirty and look really tired.”“What should opportunity look like?” the man at the door asked.“I guess he would look cool. Like a multimillionaire: wearing a tux and driving a sports car.”“It seems to me that you are confusing opportunity with extravagance,” the man at the door said. “Opportunity doesn’t wear a tuxedo. Opportunity is a diamond in the rough. You have to work with opportunity and polish it into a diamond.”
As Ashton says: you have to build your life - starting with opportunity in the rough - in order to shape and live the life you dream of.

Let me know what you think.

Vicodin, Xanax and the message

Philip Copitch, Ph.D.

Behind the humor, painkiller abuse is deadly
In the January 2014 issue of Consumer Reports, the following tidbit of information was exposed:


What I got from the sports-like shirts is: if you take this drug you don’t need to exercise to stay healthy or to be happy.

I am probably overreacting, but… I regularly work with patients that want some sort of pill to solve a medical or mental health problem. 

The fact is that putting on a comfortable shirt and exercising, often helps people physically and emotionally. 

A 15 minute walk does wonders for our mental health and our overall physical health. 

Vicodin, is also called Lortab or Norco
This combination medication is used to relieve moderate to severe pain. It contains a narcotic pain reliever (hydrocodone) and a non-narcotic pain reliever (acetaminophen). Hydrocodone works in the brain to change how your body feels and responds to pain. Acetaminophen can also reduce a fever. (WebMD)

Xanax
Xanax is used to treat anxiety and panic disorders. It belongs to a class of medications called benzodiazepines which act on the brain and nerves (central nervous system) to produce a calming effect. Xanax works by enhancing the effects of a certain natural chemical in the body (GABA). (WebMD)

Recent FDA changes concurring Vicodin
In October 2013, the U.S. Food and Drug Administration (FDA) announced changes in the way Vicodin may be prescribed by your doctor. The FDA statements starts:

Over the past several years, the U.S. Food and Drug Administration (FDA) has been carefully evaluating and weighing the appropriate use of opioid analgesic drug products. For the millions of American patients experiencing an acute medical need or living with chronic pain, opioids, when prescribed appropriately, can allow patients to manage their pain as well as significantly improve their quality of life.However, in recent years, the FDA has become increasingly concerned about the abuse and misuse of opioid products, which have sadly reached epidemic proportions in certain parts of the United States. While the value of and access to these drugs has been a consistent source of public debate, the FDA has been challenged with determining how to balance the need to ensure continued access to those patients who rely on continuous pain relief while addressing the ongoing concerns about abuse and misuse.
