A strong case for “baby number sense”Were the babies really responding to the change in numerosity? It certainly seems so.
Babies reacted similarly when presented with pairs of small numbers (2 vs 3) and distant, large numbers (4 vs 12).
And researchers controlled for several, non-numerical variables that could have influenced babies—like the total surface area of the objects, the average area devoted to each object, the total luminance of each image, and the total area occupied by each group of objects.
So babies weren’t simply attending to the continuous extent of “stuff” in each image.
In fact, other experiments suggest that babies pay more attention to change in number than they do to changes in continuous extent or surface area (Cordes and Brannon 2008).
Nor is it all “in the eye.” If babies’ feats of numerical discrimination were confined to visible objects, we might suspect that the ability is domain specific—a specialization of the visual system rather than a more general conceptual ability. But babies aren’t one-trick ponies. In addition to distinguishing visual arrays, babies can also detect differences in the number of sounds and in the number of actions (Lipton and Spelke 2003; Wood and Spelke 2005).
Babies can even understand ordinality—the idea that numbers can be arranged in order of magnitude. When 11-month old babies were presented with sequences of numerosities, they could discriminate between sequences that increased and sequences that decreased (Brannon 2002).
Of course, this doesn’t mean that babies can distinguish any two numbers. There are limits. For instance:
- Six-month old babies have a hard time distinguishing two quantities if the ratio between them is less than 2:1. In other words, they can handle 8 vs. 16, but fail to distinguish 8 vs. 12 (Xu and Arriaga 2007; Lipton and Spelke 2003)
- Nine- and 10-month olds can make finer distinctions (8 vs. 12). But even these older babies don’t seem to discriminate between 8 and 10 (Xu and Arriaga 2004; Lipton and Spelke 2003)
- Babies don’t distinguish between increasing and decreasing sequences of numbers until the approach the end of their first year. When Elizabeth Brannon tested 9-month old babies, they failed the test (Brannon 2002)

Image via WikipediaNew experimental research reveals a fascinating new world of baby cognition, one in which babies can
- recognize the approximate difference between two numbers
- keep precise track of small numbers, and
- do simple subtraction and addition problems.
Moreover, when babies perform these feats they activate the same parts of the brain that are associated with mathematical thinking in adults.
What babies know about numerosityPsychologists define “numerosity” as the number of things in a set.
Although we can get a precise measure of numerosity by counting, it’s possible to appreciate numerosity in a more approximate way.
For instance, if I ask you to glance in a crowded elevator and estimate how many people are there, you can probably make a pretty good guess.
Glance inside two elevators, and you’ll also be pretty good at guessing which one has more people in it.
All without counting.
It turns out that adult humans aren’t the only creatures who can pull this off. A variety of non-verbal creatures—including monkeys, rats, and human infants—can detect the approximate difference in magnitude between two sets (Dehaene 1999).
Show them two displays—one featuring 8 items and the other only 4 items—and they will respond differently depending on what they see.
And the difference is observable in the brain.
When 3-month old infants were shown a series of displays depicting different quantities of objects, the electrical activity of their brains changed in response (Izard et al 2008).
For example, babies were presented with a continuous stream of images, each depicting 4 objects. From image to image, the objects were arranged differently. But the total number of objects remained the same.
Infants subjected to this program showed signs of boredom.
But their brain activity (as measured by event-related potentials, or ERPs) would perk up if they were next presented with an image showing 8 objects.
What’s more, the part of the brain that was activated was the same region that lights up when adults process information about numbers (Izard et al 2008).

Image via WikipediaNow it has been more than two years since i came to meet my girlfriend in May 2008 in Kuala Lumpur and we have been grown in the last two years to a small family with our Baby-Boy Tim. In the next two or three weeks we will move to Germany and settle there for another new start of our life.

At the moment we don't see such severe problems like many of these kids in the video but it will take another year to fully recognize the different problems which he might face in the future:
- Hair growth
- missing teeth (at the moment it could be that two teeth are missing as they didn't grow yet but should have been there already)
- growth (at the lower level for its age group)

Image via WikipediaWe wanted to share some information about the EEC-Syndrome (Ectrodactyly-ectodermal-dysplasia-cleft-Syndrome) of our son as there is a high possibility that he might have this kind of genetic disorder.
- several hours for each operation
- at least 2 or 3 operations for each hand
- healing process takes several weeks

The early sign of 3 day fever (roseola infantum) is a sudden high fever (can go up to 40 degrees) and that normally lasts for three to five days. When the fever disappears, the rash will appear. This usually begins on the trunk, spreading to the legs and neck. The rash may last for few days.
There is no specific treatment or vaccines for Three Day Fever (roseola infantum), it usually goes away without any treatment.
These few days, Timmy was infected by Roseola Infantum, he had suddenly a very high fever after we came back shopping from midnight 12/04/2010 on. During the fever time, it wasn't easy to make him sleep and he cried very often. We used wet and cold wash cloth to mop his chest, back, armpit, legs and head, in order to reduce his high temperature. We did not know what caused his high fever, there was totally no sign of it (or perhaps we did not notice it).
About 2 days later (around 15/04), the fever was gone, and the rash showed up the first time on his head. Initially we thought it's some bites from ants (at that time we did not know about Roseola Infantum). But the rashes showed up more and more. It covered the neck, slowly to the chest and back, finally his arms and legs were covered. Honestly, it's scary to see that, and for sure it is the first time we experience this. These rashes are totally different which Timmy had several weeks ago.
Then I immediately checked from the internet about the symptoms, and finally found out it must be the 3 day fever. Then i was relieved to read that after the rashes, Timmy will be recovered. I checked the english information for my hubby to know about this sickness (my information was in chinese). After reading it, both of us felt no more so worried.
Here, i will post the photos. Don't be shocked when you see the photos.

Being part of the initiative “My blog is carbon neutral” is an active contribution to help the environment! All you have to do is described here. Make it happen - make it green!
“My blog is carbon neutral” is an initiative, originally started in Germany by the “Make it Green” programme, that has the goal to reduce carbon dioxide emissions. We plant a tree for your blog and thereby neutralise your blog’s carbon footprint for the next 50 years! Everyone can make a small contribution to the environment. Every tree counts!
Just write a short blog post about our programme “My blog is carbon neutral” and include one of the buttons. Send the link to your blog to CO2firstname.lastname@example.org and we plant a tree for you, neutralising the carbon dioxide emissions of your blog. The trees will be planted in the spring of 2010 by the Arbor Day Foundation. For more information about how and where the trees are planted, see the NEWS section.
Just a few easy steps to make it green:
- Write a blog post about the initiative + insert your favourite button
- E-mail the link to your post to CO2email@example.com
- We plant a tree for your blog in Plumas’!

- Take a pacifier with you and put it in the mouth of your baby when the airplane starts to take off (and lands) and look that your baby is sucking it until you don't feel anymore pressure in your own ears
- Give your baby something to eat, so that it chews during the take off and landing
- Take a bottle with fluids (water, fruit juice, milk) and feed your baby, so that it always sucks the fluids during the time when the airplane takes off or lands
