Sleep is known to have a positive impact on memory retention and recall, with scientists hypothesizing that slow-wave sleep or deep non-rapid eye movement sleep is especially important for memory retention. Research has also shown that children experience stronger memory consolidation after a good night's sleep. Working memory training has been shown to improve attention and working memory in children with deficits, and children who have completed such training have demonstrated performance improvements in reading and math. However, it is unclear whether working memory training can be used as a novel approach to improve children's sleep attributes.

What You'll Learn
Sleep and memory are connected
Sleep and memory are intimately connected. Research has shown that sleep improves memory retention and recall by between 20 and 40 percent. This connection between sleep and memory has been recognized for thousands of years, with the first record of this phenomenon dating back to the first century AD.
The link between sleep and memory is particularly evident in children. Studies have found that sleep quality and quantity are positively correlated with general cognitive abilities in children. This means that a good night's rest not only promotes physical health but also enables children's brains to function properly, consolidating memories and improving their ability to learn and recall information.
The importance of sleep for memory is further highlighted by the negative consequences of insufficient or excessive sleep. Research has shown that not getting enough sleep or getting too much sleep can lead to cognitive impairments and negatively impact memory processing and other cognitive processes. Therefore, it is essential to strive for the optimal amount of nightly sleep, as recommended for different age groups.
While the connection between sleep and memory is well-established, the underlying biological and physiological mechanisms are still being explored. Scientists have been working to understand the specific sleep stages and processes that contribute to memory consolidation and enhancement.
In terms of working memory training, there is limited research on its effectiveness in improving children's sleep. One study found that adaptive working memory training during the school day did not lead to better sleep latency, duration, bedtime consistency, or fewer sleep problems in children. However, other studies have shown that working memory training can improve attention and memory in children with Attention-Deficit/Hyperactivity Disorder (ADHD) and Specific Learning Disorders (SLDs). Thus, while working memory training may not directly improve children's sleep, it could potentially enhance their cognitive abilities, including memory.

Cognitive training improves children's memory
While there is limited research on the link between working memory training and improved sleep in children, studies have shown that cognitive training can improve children's memory.
Working memory is a key factor in academic success, as it involves the ability to attend to, work with, and recall information. Children with poor working memory abilities often struggle with academic work compared to their peers without such deficits. Working memory has been linked to inattention and disorganization in children with ADHD, and deficits in this area have also been identified as a potential cause of specific learning disorders.
Cognitive training has been shown to improve attention and working memory skills in children with deficits. Computerized cognitive training programs, such as Captain's Log, have been found to be effective in remediating working memory deficits in children. These programs involve a series of supervised sessions in a clinical setting, with strategies to address task frustration and increase motivation.
Research has shown that children who undergo cognitive training demonstrate performance improvements in reading and math. The underlying structure of cognitive abilities in children with ADHD and learning disorders seems to be well-defined, with working memory, attention, and inhibition tasks forming distinct clusters.
In addition to the benefits of cognitive training for children with deficits, there is also evidence that all children can benefit from good sleep habits to optimize memory outcomes. Sleep has been shown to benefit the consolidation of memories, and insufficient or excessive sleep can affect memory processing and other cognitive processes. Therefore, a good night's rest is key to promoting physical health and enabling the brain to function properly.

Working memory is key to academic success
Working memory is an essential component of academic success. Students' ability to use their working memory to attend to, work with, and recall information is critical to their performance in various school subjects and tasks. Children with poor working memory abilities often struggle with academic work compared to their peers without such deficits.
Working memory can be particularly challenging for children with ADHD and specific learning disorders (SLDs). These children often experience inattention and disorganization due to working memory deficits. However, studies have shown that cognitive training interventions can significantly improve their attention and working memory skills. For example, computer-based programs like Captain's Log have proven effective in remediating WM deficits in children, leading to improved performance in reading and math.
The benefits of working memory training extend beyond academic success. A good night's sleep is essential for memory consolidation, and working memory training can help children improve their sleep habits. While there is limited research on the direct impact of working memory training on children's sleep, studies suggest that intensive, adaptive cognitive training may benefit sleep latency and duration.
Additionally, adequate sleep is crucial for memory retention and recall. Studies have shown that a lack of sleep can decrease learning abilities by up to 40%. Therefore, by improving their working memory through targeted interventions, children can enhance their memory retention and recall, leading to better academic outcomes.
In conclusion, working memory is indeed key to academic success. By providing children with the necessary tools to improve their working memory, we can help them succeed in school and develop better cognitive abilities. Furthermore, the potential positive impact of working memory training on sleep habits and memory retention underscores the importance of investing in interventions that target this critical cognitive skill.

Adaptive working memory training does not improve children's sleep
While improving children's sleep could lead to significant benefits, there is limited research on whether intensive, adaptive cognitive training can help. A study conducted in Melbourne, Australia, with 452 children with low verbal and/or visuo-spatial working memory (WM) scores, found that adaptive working memory training did not lead to better sleep latency, duration, bedtime consistency, or fewer sleep problems. The study concluded that this type of training during the school day cannot be used as a novel approach to improve children's sleep attributes up to 6 months post-randomisation, regardless of the time of day the training is delivered.
However, it is important to note that this study focused specifically on the impact of working memory training on children's sleep. Other types of cognitive training or interventions may still hold potential for improving children's sleep. Furthermore, while the study found no significant improvements in sleep attributes, it did not examine other potential benefits of working memory training, such as improved academic performance or cognitive abilities.
The study's results also align with existing research suggesting that sleep benefits the consolidation of memories, especially in adults. This indicates that while adequate sleep is essential for cognitive functions, including memory, the specific mechanism of memory consolidation during sleep is still not fully understood.
Additionally, the effectiveness of working memory training in children with low working memory skills has been explored in other studies. One such study found that adaptive training that taxed working memory to its limits resulted in substantial and sustained gains in working memory, with age-appropriate levels achieved by most participants. This indicates that working memory training can be beneficial for children with low working memory skills, improving their cognitive abilities, but it may not directly translate to improved sleep attributes.

Sleep loss lowers learning abilities
Sleep has been shown to improve memory retention and recall by between 20 and 40 percent. Recent research has led scientists to hypothesize that deep non-rapid eye movement (NREM) sleep, or slow-wave sleep, may be especially important for the improvement of memory retention and recall. MRI scans indicate that the slow brain waves of this stage of sleep serve as a "courier service", transporting recently learned information to our brains for storage. This process is known as memory consolidation, and it is the process of preserving key memories and discarding excessive information. Memory consolidation takes place during both the NREM and rapid eye movement (REM) stages of the sleep cycle.
Sleep research from the last 20 years indicates that sleep does more than simply give students the energy they need to study and perform well on tests. Sleep helps students learn, memorize, retain, recall, and use their new knowledge to come up with creative and innovative solutions. For example, participants in a study who were woken up during REM sleep could solve 15 to 35 percent more puzzles than when they were woken up from NREM sleep. They also performed 15 to 35 percent better than they did in the middle of the day. This suggests that REM sleep may play a major role in improving the ability to solve complex problems.
However, the beneficial effect of sleep on working memory performance is still not entirely clear. While various skills are reported to be improved by sleep, the impact on working memory performance has not been fully substantiated.

Frequently asked questions
Sleep in comparison to wakefulness benefits the consolidation of memories. A good night's rest enables our brains to function properly, allowing us to process new information and solidify our memories.
Sleep helps with memory consolidation by sorting through our memories from the previous day, filtering out important memories and eliminating other information. During deep NREM sleep, these selected memories become more concrete, and this process continues during REM sleep.
Working memory training has been shown to improve attention and working memory skills in children with ADHD and SLD. It also helps to address inattention and disorganization, which are common issues for children with ADHD.
There is limited research on whether working memory training can improve children's sleep. One study found that adaptive working memory training during the school day did not lead to better sleep latency, duration, bedtime consistency, or fewer sleep problems.
