Do Babies Forget About Objects Which is Not in Their View ?

Researchers sought to understand the memory of babies by trying to see if they actually remembered objects which are not currently in their view.

But in the mid-1980s, new ways of doing experiments with babies found that they do, in fact, know that objects don't disappear when you're not looking at them-a concept known as object permanence.

Soon, Fashionable E-garments With Memory Retention
Integrating electronics into textiles will soon enable smart fabrics and wearable electronics, researchers say.

However, it was still unknown what babies needed to remember about objects in order to remember their existence.

Now, a new study has found that when babies "forget" about an object, not all is lost.

Melissa Kibbe, of Johns Hopkins University, and Alan Leslie, of Rutgers University, wanted to figure out exactly what it is that babies remember about objects.

'Sleep Memory' Explored in New Study
A study by Michigan State University researchers suggests people may be learning while they're sleeping – an unconscious form of memory that is still not well understood.

For the new study, they showed six-month-old babies two objects, a disk and a triangle. Then they hid the objects behind small screens, first one shape, then the other.

In Kibbe and Leslie's study, babies weren't particularly surprised to see that the shape hidden behind the screen had changed, for example, from a triangle to a disk.

Cancer Protein Also Plays a Role as Memory Regulator
Scientists at the Dana-Farber Cancer Institute and Harvard Medical School have found that a key cancer protein could help regulates memory formation - a finding that could pave the

But if the object was gone altogether, the babies looked significantly longer, indicating surprise at an unexpected outcome.

"This shows that even though infants don't remember the shape of the object, they know that it should continue to exist," Kibbe said.

Smokers Risk Losing Everyday Memory Very Fast: Study
People who smoke have a higher risk of losing around one third of their everyday memory, more so than non-smokers, a study has revealed.

"They remember the object without remembering the features that identify that object," she explained.

Leslie suspects the brain has a mechanism that acts like a kind of pointer, a mental finger that points at an object. Each finger can only point to one object.

This study shows that the mechanism in the baby's brain that remembers the object doesn't have to remember much about it.

The finding will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science.
