Working memory can help tailor educational development

Psychology researchers at the University of Missouri suggest a first step toward creating educational and work materials to fit a person's appropriate developmental level

Working memory can help tailor educational development
2021-01-27
(Press-News.org) Imagine a 7-year-old and a college student both take a break from their virtual classes to get a drink of water. When they return, the 7-year-old has difficulty restarting the assignment, while the college student resumes working as if the break never occurred. Nelson Cowan, an expert in working memory at the University of Missouri, believes understanding this developmental age difference can help younger children and their parents to better adjust to a virtual learning environment during the COVID-19 pandemic.

"By understanding this developmental difference, then we can work to provide a little more structure for younger children in online settings, such as helping them organize their homework," said Cowan, a Curators Distinguished Professor in the Department of Psychological Sciences. "At school, teachers can provide more of that structure, but in a virtual environment, parents may also have to take on more of that responsibility. For parents who have younger children that are somewhat resistant to their actions, this might be difficult to do, however it needs to be made clear to children that their parents are assisting their teacher, rather than being the primary educational figure."

Kendall Holzum can relate. During the COVID-19 pandemic, the 7-year-old girl has been going to school online instead of in person.

"Sometimes it's hard to remember to go back and do your homework after you get off your Zoom call," Holzum said. "My parents have to help me a lot to remember to do my assignments. Homework is the hardest to follow directions on because your teacher isn't there to always help you."

Cowan, who has been interested in how the human brain works since he was a young child, suggests this insight can be a first step toward helping educators determine how to tailor a child's individual learning experience to their appropriate developmental level.

"Now, the challenge will be to understand how to adapt educational materials and work materials to be appropriate for each individual's developmental level in an online setting and perhaps try to teach children to be more proactive in their thinking," Cowan said. "I'm hoping this is a first step toward that notion and encourages people who do research in the classroom, or now in the virtual classroom, to consider the role of proactive behavior as an overall life skill and how to accommodate various levels of learning to meet that life goal."

A total of 180 people participated in the study by Cowan and his colleagues. Participants were split among three different age groups -- children ages 6-8, ages 10-14 and college students. Each age group was asked to remember a display of colored spots. Then, they were interrupted by a second, unexpected and more urgent task -- quickly pressing a button when a signal is heard or seen. Upon completion of the second task, they were asked to return to the first task and decide if a color came from the display. Cowan said more often, the younger children simply forgot to remember the colors they were supposed to recall after working on the second task. He said this study provides a clear example of the limits of working memory in younger children.

"In general, working memory is limited," Cowan said. "As the amount of things a person is trying to remember at one time increases, less memory is available to help remember a task, or what a person is supposed to be doing. An example of the difference between an adult and a child is when both try to catch a ball while carrying dishes. The child would be more likely to drop the dishes, while the adult remembers to also hold onto the dishes at the same time. Virtual school has created a whole new environment, and this study provides us with a first step in how we must help children adjust as some parts of virtual schooling are very likely to be here for a long time."

"Developmental change in the nature of attention allocation in a dual task," was published in Developmental Psychology. The study was funded by the National Institute of Child Health and Human Development (R01 HD-021338).

Juicing technique could influence healthfulness of fresh-squeezed juice

2021-01-27
With the New Year, many people are making resolutions to eat healthier, by eating more vegetables, for example. But those who don't like the taste or texture of some vegetables might prefer to drink them in a home-squeezed juice. Now, researchers reporting in ACS Food Science & Technology have found that the choice of household juicing technique can influence the phytochemical content and antioxidant activity of common vegetable juices. Home juicing machines have become popular in recent years, with different types available. For example, blenders crush vegetables with fast, spinning blades, and the resulting juice is typically thick, with much pulp and dietary fiber. In contrast, high-speed centrifugal juicers quickly pulverize veggies and separate out pulp and ...

Scientists develop perovskite solar modules with greater size, power and stability

2021-01-27
Perovskites are projected to be a game-changer in future solar technology but currently suffer from a short operational lifespan and drops in efficiency when scaled up to a larger size Scientists have improved the stability and efficiency of solar cell modules by mixing the precursor materials with ammonium chloride during fabrication The perovskite active layer in the improved solar modules are thicker and have larger grains, with fewer defects Both 5 x 5 cm2 and 10 x 10 cm2 perovskite modules maintained high efficiencies for over 1000 hours Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have created perovskite solar ...

A mild way to upcycle plastics used in bottles into fuel and other high-value products

2021-01-27
Plastic is ubiquitous in people's lives. Yet, when plastic-containing items have fulfilled their missions, only a small amount is recycled into new products, which are often of lower quality compared to the original material. And, transforming this waste into high-value chemicals requires substantial energy. Now, researchers reporting in ACS' JACS Au have combined a ruthenium-carbon catalyst and mild, lower-energy reaction conditions to convert plastics used in bottles and other packaging into fuels and chemical feedstock. Global production of sturdy, single-use plastic for toys, sterile medical packaging, and food and beverage containers is increasing. Polyolefin polymers, such as polyethylene and ...

New Tel Aviv University study reveals 'Achilles' heel' of cancer cells

2021-01-27
What makes cancer cells different from ordinary cells in our bodies? Can these differences be used to strike at them and paralyze their activity? Cancer researchers have been debating this question since the mid-19th century. A new study from Tel Aviv University (TAU) shows, for the first time, how an abnormal number of chromosomes (aneuploidy) -- a unique characteristic of cancer cells that researchers have known about for decades -- could become a weak point for these cells. The study could lead to the development of future drugs that will use this vulnerability to eliminate the cancer cells. The study was conducted in the laboratory of Dr. Uri Ben-David of TAU's Sackler Faculty of Medicine, in collaboration with six laboratories ...

First ever 'pioneer' factor found in plants enables cells to change their fate

First ever pioneer factor found in plants enables cells to change their fate
2021-01-27
Cells don't express all the genes they contain all the time. The portion of our genome that encodes eye color, for example, doesn't need to be turned on in liver cells. In plants, genes encoding the structure of a flower can be turned off in cells that will form a leaf. These unneeded genes are kept from becoming active by being stowed in dense chromatin, a tightly packed bundle of genetic material laced with proteins. In a new study in the journal Nature Communications, biologists from the University of Pennsylvania identify a protein that enables plant cells to reach these otherwise inaccessible genes in order to switch between different identities. Called ...

Up-trending farming and landscape disruptions threaten Paris climate agreement goals

2021-01-27
Irvine, Calif., Jan. 27, 2021 -- One of President Joe Biden's first post-inauguration acts was to realign the United States with the Paris climate accord, but a new study led by researchers at the University of California, Irvine demonstrates that rising emissions from human land-use will jeopardize the agreement's goals without substantial changes in agricultural practices. In a paper published today in Nature, the team presented the most thorough inventory yet of land-use contributions to carbon dioxide and other greenhouse gases (including nitrous oxide and methane) from 1961 to 2017, taking into account emissions from agricultural production activities and modifications to the natural landscape. "We estimated and attributed global land-use emissions among 229 countries ...

Fields of breeders' dreams: A team effort toward targeted crop improvements

Fields of breeders dreams: A team effort toward targeted crop improvements
2021-01-27
Gardeners and farmers around the country recognize that crop varieties grow best in certain regions. Most plant species have adapted to their local environments; for example, crop and ornamental seeds sold for the upper Midwest are often very different than those bred for Texas. Identifying and breeding varieties that have high productivity across a range of environments is becoming increasingly important for food, fuel and other applications, and breeders aren't interested in waiting decades to develop new crops. One example is an ongoing collaborative effort to improve the emerging bioenergy crop ...

Focusing on field analysis

Focusing on field analysis
2021-01-27
The development of cost-efficient, portable microscopy units would greatly expand their use in remote field locations and in places with fewer resources, potentially leading to easier on-site analysis of contaminants such as E. coli in water sources as well as other practical applications. Current microscopy systems, like those used to image micro-organisms, are expensive because they are optimized for maximum resolution and minimal deformation of the images the systems produce. But some situations do not require such optimization--for instance, simply detecting the presence of pathogens in water. One potential approach to developing a low-cost portable microscopy system is to use transparent microspheres in combination with affordable ...

Purported phosphine on Venus more likely to be ordinary sulfur dioxide, new study shows

Purported phosphine on Venus more likely to be ordinary sulfur dioxide, new study shows
2021-01-27
In September, a team led by astronomers in the United Kingdom announced that they had detected the chemical phosphine in the thick clouds of Venus. The team's reported detection, based on observations by two Earth-based radio telescopes, surprised many Venus experts. Earth's atmosphere contains small amounts of phosphine, which may be produced by life. Phosphine on Venus generated buzz that the planet, often succinctly touted as a "hellscape," could somehow harbor life within its acidic clouds. Since that initial claim, other science teams have cast doubt on the reliability of the phosphine ...
