MedicineNet.com defines working memory in the article, Definition of Working memory:
Working memory is a system for temporarily storing and managing the information required to carry out complex cognitive tasks such as learning, reasoning, and comprehension. Working memory is involved in the selection, initiation, and termination of information-processing functions such as encoding, storing, and retrieving data.
One test of working memory is memory span, the number of items, usually words or numbers, that a person can hold onto and recall. In a typical test of memory span, an examiner reads a list of random numbers aloud at about the rate of one number per second. At the end of a sequence, the person being tested is asked to recall the items in order. The average memory span for normal adults is 7 items. http://www.medterms.com/script/main/art.asp?articlekey=7143
The University of Pennsylvania researchers studied working memory in a longitudinal study. See, Penn and CHOP Researchers Track Working Memory From Childhood Through Adolescence http://www.upenn.edu/pennnews/news/penn-and-chop-researchers-track-working-memory-childhood-through-adolescence
Science Daily reported in the article, How curiosity changes the brain to enhance learning:
The more curious we are about a topic, the easier it is to learn information about that topic. New research publishing online October 2 in the Cell Press journal Neuron provides insights into what happens in our brains when curiosity is piqued. The findings could help scientists find ways to enhance overall learning and memory in both healthy individuals and those with neurological conditions.
“Our findings potentially have far-reaching implications for the public because they reveal insights into how a form of intrinsic motivation — curiosity — affects memory. These findings suggest ways to enhance learning in the classroom and other settings,” says lead author Dr. Matthias Gruber, of University of California at Davis.
For the study, participants rated their curiosity to learn the answers to a series of trivia questions. When they were later presented with a selected trivia question, there was a 14 second delay before the answer was provided, during which time the participants were shown a picture of a neutral, unrelated face. Afterwards, participants performed a surprise recognition memory test for the faces that were presented, followed by a memory test for the answers to the trivia questions. During certain parts of the study, participants had their brains scanned via functional magnetic resonance imaging.
The study revealed three major findings. First, as expected, when people were highly curious to find out the answer to a question, they were better at learning that information. More surprising, however, was that once their curiosity was aroused, they showed better learning of entirely unrelated information (face recognition) that they encountered but were not necessarily curious about. People were also better able to retain the information learned during a curious state across a 24-hour delay. “Curiosity may put the brain in a state that allows it to learn and retain any kind of information, like a vortex that sucks in what you are motivated to learn, and also everything around it,” explains Dr. Gruber.
Second, the investigators found that when curiosity is stimulated, there is increased activity in the brain circuit related to reward. “We showed that intrinsic motivation actually recruits the very same brain areas that are heavily involved in tangible, extrinsic motivation,” says Dr. Gruber. This reward circuit relies on dopamine, a chemical messenger that relays messages between neurons.
Third, the team discovered that when curiosity motivated learning, there was increased activity in the hippocampus, a brain region that is important for forming new memories, as well as increased interactions between the hippocampus and the reward circuit. “So curiosity recruits the reward system, and interactions between the reward system and the hippocampus seem to put the brain in a state in which you are more likely to learn and retain information, even if that information is not of particular interest or importance,” explains principal investigator Dr. Charan Ranganath, also of UC Davis.
The findings could have implications for medicine and beyond. For example, the brain circuits that rely on dopamine tend to decline in function as people get older, or sooner in people with neurological conditions. Understanding the relationship between motivation and memory could therefore stimulate new efforts to improve memory in the healthy elderly and to develop new approaches for treating patients with disorders that affect memory. And in the classroom or workplace, learning what might be considered boring material could be enhanced if teachers or managers are able to harness the power of students’ and workers’ curiosity about something they are naturally motivated to learn.

Highlights
• •People are better at learning information that they are curious about
• •Memory for incidental material presented during curious states was also enhanced
• •Curiosity associated with anticipatory activity in nucleus accumbens and midbrain
• •Memory benefits for incidental material depend on midbrain-hippocampus involvement
Summary
People find it easier to learn about topics that interest them, but little is known about the mechanisms by which intrinsic motivational states affect learning. We used functional magnetic resonance imaging to investigate how curiosity (intrinsic motivation to learn) influences memory. In both immediate and one-day-delayed memory tests, participants showed improved memory for information that they were curious about and for incidental material learned during states of high curiosity. Functional magnetic resonance imaging results revealed that activity in the midbrain and the nucleus accumbens was enhanced during
states of high curiosity. Importantly, individual variability in curiosity-driven memory benefits for incidental material was supported by anticipatory activity in the midbrain and hippocampus and by functional connectivity between these regions. These findings suggest a link between the mechanisms supporting extrinsic reward motivation and intrinsic curiosity and highlight the importance of stimulating curiosity to create more effective learning experiences.

Parents can help foster curious kids.
Justin Coulson writes in the article, Raising smart, curious children:
Parents can do several things that will foster curiosity and a love of learning in their children, and help them grow up intellectually stimulated and successful.
• Model a love of learning. Be seen reading, finding answers, and discovering things yourself. Your children will watch and learn from you.
• Embrace the motto “we try new things”. Whether it is a new meal, a new sport, a new holiday destination, or a new way of cleaning the house, let your children know that you want to try new things and discover things you previously did not know much about.
• Teach your children to find answers. When your children ask you a question, rather than answering them directly encourage them to find out for themselves. Point them to references, the Internet, or other useful sources.
• Ask questions. If your child is curious about something, find out why. Encourage discussion. Find out what s/he knows already. When your child makes a statement (about anything) you can ask “why” and have an interesting conversation. Your demonstration of curiosity can be a terrific example to your children
• Be willing to talk. It is often easy for a parent to say “I’ll tell you later”, or “Not now, I’m busy.” Such responses will dampen the enthusiasm and curiosity a child has for a subject. Be being available, your child will be able to pursue a love of learning and all you have to do is facilitate it.
• Provide tools for learning by visiting the library, buying books from the shops, and having access to the Internet available for appropriate learning activities.
• Eliminate the use of rewards for learning. Research shows that the more we reward someone for a task, the less interested they become in the task. When rewards are offered, people generally become more interested in the reward than in the process required to obtain the reward. Instead, encourage curiosity for its own sake….. http://www.kidspot.com.au/schoolzone/Study-tips-Raising-smart-curious-children+4165+304+article.htm
Education is a partnership and parents must help educators foster curiosity in children.
The important thing is not to stop questioning. Curiosity has its own reason for existing.
