Working memory differs by parents' education; effects persist into adolescence

30.04.2014

Working memory—the ability to hold information in your mind, think about it, and use it to guide behavior—develops through childhood and adolescence, and is key for successful performance at school and work.

Previous research with young children has documented socioeconomic disparities in performance on tasks of working memory. Now a new longitudinal study has found that differences in working memory that exist at age 10 persist through the end of adolescence.

The study also found that parents' education—one common measure of socioeconomic status—is related to children's performance on tasks of working memory, and that neighborhood characteristics—another common measure of socioeconomic status—are not.

The study, conducted by researchers at the University of Pennsylvania, the Children's Hospital of Philadelphia, West Chester University, and the University of Pennsylvania School of Medicine, appears in the journal Child Development.

"Understanding the development of disparities in working memory has implications for education," according to Daniel A. Hackman, a postdoctoral scholar at the University of Pittsburgh who led the study when he was a graduate student at the University of Pennsylvania. "Persistent disparities are a potential source of differences in academic achievement as students age and as the demands of both school work and the social environment increase.

"Our findings highlight the potential value of programs that promote developing working memory early as a way to prevent disparities in achievement," Hackman continues. "The fact that parents' education predicts working memory suggests that parenting practices and home environments may be important for this aspect of cognitive development and as a fruitful area for intervention and prevention."

To look at the rate of change in working memory in relation to different measures of socioeconomic status, the researchers studied more than three hundred 10- through 13-year-olds from urban public and parochial schools over four years. The sample of children was racially, ethnically, and socioeconomically diverse. Each child completed a number of tasks of working memory across the four-year period. The researchers gathered information on how many years of education the parents of each child had completed, as well as on neighborhood characteristics, looking—for example—at the degree to which people in a child's neighborhood lived below the poverty line, were unemployed, or received public assistance.

Neither parents' education nor living in a disadvantaged neighborhood was found to be associated with the rate of growth in working memory across the four-year period. Lower parental education was found to be tied to differences in working memory that emerged by age 10 and continued through adolescence. However, neighborhood characteristics were not related to working memory performance.

The study suggests that disparities seen in adolescence and adulthood start earlier in childhood and that school doesn't close the gap in working memory for children ages 10 and above. Generally, children whose parents had fewer years of education don't catch up or fall further behind by the end of adolescence, when working memory performance reaches mature levels.

That said, the findings of this study do not suggest that working memory is not malleable. Interventions that strengthen working memory in children, such as training games, may help children with lower levels of working memory improve and reduce disparities.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
