Working memory affects cognitive processing

Memory is the term given to the structures and processes involved in the storage and subsequent retrieval of information. Memory is essential to all our lives. Without a memory of the past, we cannot operate in the present or think about the future. We would not be able to remember what we did yesterday, what we have done today or what we plan to do tomorrow.

Can you add together 23 and 69 in your head? Remember a list of grocery store items without writing them down? Recall the seating arrangements of a dinner party after a brief glimpse at the table?

People with larger capacities can juggle more information at once. This helps them process information more quickly, and the benefits are well-documented. People with higher-than-average WMC are more likely to excel in the classroom. On the flip side, individuals with poor WM skills at a disadvantage.

They are more likely to struggle with mathematics and reading. They may also struggle with following spoken directions. Please give me your drawing, then put away the crayons and clean up your desk. It might sound easy to you. But for younger children -- who have lower capacities than adults do -- these instructions may cause an information overload.

The same thing is true for older kids who have low WMC for their age. There is too much to juggle, so they lose track of what they are supposed to do. Is this just another way of describing an individual as "intelligent? WM seems to be a basic component of fluid intelligence. It affects how kids learn.

It also influences how kids perform on tests, including achievement tests and IQ tests. How is this possible? In recent experiments, researchers found that individual differences in WMC had no effect on whether or not people fall prey to belief bias, a common failure of logical reasoning Robinson and Unsworth For example, children diagnosed with developmental dyscalculia -- a learning disability relating to arithmetic -- perform normally on many tests of WMC, except one: They are less likely to remember the precise order of items on a list Attout and Majerus What about other learning disabilities?

In addition to dyscalculia, reading problems are also linked with WM. Compared with typically developing children, kids who have been diagnosed with attention deficit disorder are more likely to have WM difficulties Kuhn et al ; Alderson et al For example, in WM tasks dependent on tracking items in a briefly-presented visual array, adults remember approximately 3 or 4 objects Cowan Five-year-olds recall only half as many Riggs et al So how can we tell if a child has low WMC for his or her age?

How can we identify them? But we can also get a good idea of who is struggling by observing everyday behavior. According to Susan Gatherole and Tracey Allowaythe typical child with WM difficulties shows the following signs.

He or she has normal social relationships with peers; is reserved during group activities in the classroom, and sometimes fails to answer direct questions; finds it difficult to follow instructions; loses track during complicated tasks, and may eventually abandon these tasks; makes place-keeping errors skipping or repeating steps ; shows incomplete recall; appears to be easily distracted, inattentive, or "zoned out"; and has trouble with activities that require both storage remembering and processing manipulating information.

What can we do to boost working memory skills? Can we enhance WM through the repeated practice of simple memory games? You might have heard of computer-based memory games that are supposed to enhance WM, or even IQ.

Do they actually work? It depends on what you mean by "work. In one study, researchers identified kids with low WMC, and assigned these children to play a series of computer games designed to challenge their WM skills Holmes et al Hearing a series of letters read aloud "G, W, Q, T, F…" and repeating them back Watching a battery of lamps light up, one at a time, and then recalling the correct sequence by clicking the correct locations with a computer mouse.

Hearing and watching a sequence of numbers while they are spoken aloud and flashed on a keypad. After each sequence, the student is asked to reproduce the sequence in reverse order by hitting the correct digits on the keypad.

For children in a control group, the difficulty level of these tasks remained easy throughout the study. But for kids in the treatment group, the program was adaptive--i.

It’s important to understand the characteristics of working memory when you’re designing something that requires mental effort. Without adapting learning experiences to the learner’s cognitive architecture, instructional design is hit or miss. How the cognitive load of a learning task affects a person's ability to memorize it. A new study reports the rhythm of your breathing can influence neural activity that enhances memory recall and emotional judgement.

While both groups improved, the kids in the adaptive program did much better. Their average gains were 3 to 4 times higher than those of kids in the control group."Life comes at us very quickly, and what we need to do is take that amorphous flow of experience and somehow extract meaning from it." In this funny, enlightening talk, educational psychologist Peter Doolittle details the importance -- and limitations -- of your "working memory," that part of the brain that allows us to make sense of what's happening right now.

Cognitive Theory of Multimedia Learning 4 processed by memory. Each form represents a particular stage of processing in the three memory stores model of multimedia.

Scores for both the Working Memory and Processing Speed subtests make up the WISC-IV’s Cognitive Proficiency Index. These abilities are separate from the WISC-IV’s General Abilities Index, a measure of core intelligence derived from an individual’s Verbal Comprehension and Perceptual Reasoning Indices (verbal and nonverbal abilities).
