The Reading Span Task, originally designed by Daneman and Carpenter (1980), is widely used to measure verbal WM. The alpha power was considered important in the maintenance of working memory items; and lower working memory accuracy paired with lower alpha band power was indeed observed in the ADHD group (Liu et al., 2016). Individual differences in working memory and reading. Memory outcome at 5 years post-childhood traumatic brain injury. Clinicians will likely use one or more working memory available on the WISC-V in most clinical evaluations. While in WM, information can be used and manipulated by other cognitive processes such as planning, reasoning, and decision–making, WM can reliably hold only four chunks of information for a brief period of time (Cowan, 2001). That was a sequence of 12 digits. The WM intervention combined training for pupils in strategies to improving working memory and time for them to practise these. Instead of holding relevant information through heightened and persistent neuronal firing, residual calcium at the presynaptic terminals was suggested to have mediated the working memory process (Mongillo et al., 2008). For example, in the visuo-spatial 2-back task by Dong, Liu, and Cai (2018), which was adapted from Soveri, Rodriguez-Fornells, and Laine (2011), a square was presented in one of 25 possible locations on the screen, and participants were asked to determine whether the location of the current square matched the location of the square before the previous one (2-back).b. Brain Behav. A meta-analysis of working memory impairments in survivors of moderate-to-severe traumatic brain injury. In theory, the neural efficiency hypothesis explains that increased efficiency of the neural processes recruit fewer cerebral resources in addition to displaying lower activation in the involved neural network (Vartanian et al., 2013; Rodriguez Merzagora et al., 2014). In fact, the allocated cognitive resources for a task (such as provided attention) and the duration of such allocation dictated the likelihood of success in performing the tasks (Barrouillet et al., 2004, 2009; Barrouillet and Camos, 2007).

Besides, a study conducted on mice yielded a similar conclusion in which the mediodorsal thalamus aided the medial prefrontal cortex in the maintenance of working memory (Bolkan et al., 2017). Our working memory is severely limited in both capacity (the amount of information it can hold) and duration. 20, R136–R140. Nonetheless, after overlooking the underlying neural mechanism relating to emotional distractors, it was still agreed that effective emotional processing sustained working memory performance among older/elderly people (Oren et al., 2017; Ziaei et al., 2017). A simplified depiction (adapted from the multicomponent working memory model by Baddeley, 2010) as implicated in the brain, in which the central executive assumes the role to exert control and oversee the manipulation of incoming information for intended execution. Head Trauma Rehabil. Front. In contrast, significant correlation between estradiol and other cortical activations in females in the midluteal phase, who had higher estradiol levels, did not result in better performance of the task compared to women in the EF phase or men (Schöning et al., 2007). Curr. Soc. Arch. doi: 10.1037/10039-000, Miyake, A., and Shah, P. (eds). ACC, Anterior cingulate cortex. (2016). 20, 987–996. The WMI allows full construct coverage of working memory across both sensory modalities (visual and auditory). (2016). Verbal and visuospatial working memory as predictors of children’s reading ability. No consensus has been reached, however, among the few empirical studies (e.g., Gooch, Thompson, Nash, Snowling, & Hulme, 2016; Kuhn et al., 2014) investigating the relationship between cognitive control and language skills Kuhn et al. Unless you cheated (or cleverly spotted a pattern—more on that soon), you would not have been able to retain all those digits and repeat them correctly after closing your book cover. Time constraints and resource sharing in adults’ working memory spans. Dev. Radiology 276, 828–835. In another study by Murty et al. Indeed, Ashkenazi et al. Discernable implications can be derived from the functional WM model of ADHD. Further categorizations of long-term memory include several categories: (1) episodic; (2) semantic; (3) Pavlovian; and (4) procedural memory (Humphreys et al., 1989). Aging 32, 732–746. Thalamic projections sustain prefrontal activity during working memory maintenance. And at the end of the trial, participants reported the final resulting number(s) in each grid. Neuropsychologia visuo – spatial working memory is an important source of domain-general vulnerability in the development of arithmetic cognition. Working memory is often associated with attention and executive functioning skills. Neurocognitive ageing and the compensation hypothesis. In clinical situations in which the visual modality is impaired, the AWMI allows better evaluation of working memory functions than the WMI. doi: 10.1097/HTR.0b013e3181c133e9, Dima, D., Jogia, J., and Frangou, S. (2014). There are three dimensions for a response card: color, shape and number (e.g., a response card with three green squares), and each response card matches one of the four stimulus cards by one of the three dimensions. Thus, the concept of working memory that shares similarities with short-term memory but attempts to address the oversimplification of short-term memory by introducing the role of information manipulation has emerged (Baddeley, 2012). These test variations undeniably present further difficulties in selecting an appropriate task. The late follicular (LF) phase of the menstrual cycle, characterized by high estradiol levels, was shown to recruit more of the right hemisphere that was associated with improved working memory performance than did the early follicular (EF) phase, which has lower estradiol levels although overall, the direct association between estradiol levels and working memory was inconclusive (Joseph et al., 2012). Working memory training is associated with lower prefrontal cortex activation in a divergent thinking task. doi: 10.1016/S0079-7421(03)44005-X, Farrer, T. J. 27, 151–177. Neuropharmacology 64, 160–167. In short, cognitive control is indispensable to a normal functioning person (e.g., Diamond, 2013), and its development may interact with the development of language. 265, 303–311. With these core functions, people can perform more complex functions such as reasoning, planning, and problem solving (e.g., Collins & Koechlin, 2012). Nonetheless, it is to be noted that such findings relating to age of injury could not be generalized to the child population since results from the pediatric TBI cases showed that damage could negatively impact developmental skills that could indicate a greater lag in cognitive competency as the child’s frontal lobe had yet to mature (Anderson and Catroppa, 2007; Mandalis et al., 2007; Nadebaum et al., 2007; Gorman et al., 2012). Psychol. 5, 87–96. 4, 417–423. doi: 10.1016/S1364-6613(00)01538-2. The visual sketchpad allows people to keep visual images and spatial information active in the mind for problem-solving. The primary WMI is comprised of Digit Span and Picture Span, which are auditory and visual working memory tasks, respectively. doi: 10.1016/j.cub.2009.12.014, Baddeley, A. WC and AAH contributed to the final version of the manuscript. Training working memory in older adults: is there an advantage of using strategies? WM temporarily holds active information, either perceived from the environment or retrieved from LTM, keeping it available for a brief time while we use it or until we store it in LTM (Baddeley, 2012). More » Regular exercise adds up to big memory boosts The Improving Working Memory (WM) and Working Memory Plus intervention (WM+) both build on evidence from cognitive science which suggests that numeracy difficulties may be related to poor working memory capacity. JA supervised the process and proofread the manuscript. Neuropsychologia 51, 2305–2317. Children diagnosed with dyslexia show deficits on verbal working memory measures and not spatial working memory (Jeffries & Everatt, 2004). Nat. Psychol. 38, 262–276. The need for psychology and neuroscience to interact with each other in an active feedback cycle exists in which this cognitive system called working memory can be dissected at the biological level and refined both empirically, and theoretically. Increased activation in the brain during 6-week follow-up was also observed in the mild TBI participants, implicating the regaining of connections in the brain (Chen et al., 2012). doi: 10.1037/a0014296, Daneman, M., and Carpenter, P. A. Definition: Working Memory is the active maintenance and flexible updating of goal/task relevant information (items, goals, strategies, etc.) Therefore, the decrease in activation in female patients, in addition to the observed worse performance, was speculated to be due to a more serious injury sustained by the female patients group (Hsu et al., 2015). Working memory, sometimes called short-term memory, refers to the processes that allow us to hold on to and manipulate information we are currently aware of and working on. doi: 10.1037/pag0000155, Chein, J. M., Moore, A. In the classroom, working memory is critical to learning situations involving literacy and numeracy; it is also vital to social situations.A strong correlation has been found between certain LDs and working memory difficulties. Psychol. In 2000, post-menopausal women undergoing hormone replacement therapy, specifically estrogen, were found to have better working memory performance in comparison with women who took estrogen and progestin or women who did not receive the therapy (Duff and Hampson, 2000). Behav. Neuroimage 54, 550–559. Nonetheless, it remains premature to conclude that age-related cognitive decline was a result of hormonal (estradiol or testosterone) fluctuations although hormones might have modulated the effect of aging on working memory. Working memory is often associated with attention and executive functioning skills. The relationships between short-term, long-term, and working memory could be presented in a hierarchical manner whereby in the domain of long-term memory, there exists an intermediate subset of activated long-term memory (also the short-term storage component) and working memory belongs to the subset of activated long-term memory that is being attended to (Cowan, 1999, 2008). Front. Therefore, altered visual cortical functions and load-related activation in the prefrontal cortex in the MDD group implied that the cognitive control for visual information processing and updating might be impaired at the input or control level, which could have ultimately played a part in the depressive symptoms (Le et al., 2017). The reviewer EB and handling Editor declared their shared affiliation. Research on cognitive deficits in traumatic brain injury has been extensive due to the debilitating conditions brought upon an individual daily life after the injury. The effect of caffeine on working memory load-related brain activation in middle-aged males. doi: 10.1177/0963721409359277, Dahlin, E., Nyberg, L., Bäckman, L., and Neely, A. S. (2008). Neuropsychol. The number of completed categories and various error rates are the main indicators of WCST performance. Individ. Inhibitory control, on the other hand, is what we need if we have to inhibit or resist habitual responses or external lures. Adding on to these results, using EEG to examine the functional consequences of CC damage revealed that interhemispheric transfer time (IHTT) of the CC was slower in the TBI group than the control group, suggesting an inefficient communication between the two hemispheres (Ellis et al., 2016). Working memory in patients with mild traumatic brain injury: functional MR imaging analysis. J. Neurosci. 12, 407–414. Verbal Behav. Different ways to cue a coherent memory system: a theory for episodic, semantic, and procedural tasks. Taken together, these outcomes offered insight at the neurobiological level in which caffeine acts as a psychoactive agent that introduces changes and alters the aging brain’s biological environment that explicit behavioral testing might fail to capture due to performance maintenance (Haller et al., 2013, 2017; Klaassen et al., 2013). 66, 115–142. The researchers from the study further explained that such hyperactivation after the trauma acted as a neural compensatory mechanism so that task performance could be maintained while hypoactivation with a poorer performance could have been the result of a more severe injury (Hsu et al., 2015). In fact, it was reported that decreases in cortical surface area in the frontal lobe of the right hemisphere was associated with poorer performers (Nissim et al., 2017). doi: 10.1371/journal.pone.0126110, Ziaei, M., Salami, A., and Persson, J. Working memory is generally considered to be a limited capacity system responsible for temporarily storing, maintaining, and mentally manipulating information over brief time periods to serve other ongoing cognitive activities and operations. Annu. doi: 10.1016/j.jecp.2012.11.015, Wylie, G. R., Freeman, K., Thomas, A., Shpaner, M., OKeefe, M., Watts, R., et al. Intertemporal decision-making involves prefrontal control mechanisms associated with working memory. Working memory after severe traumatic brain injury. Such direct effects of caffeine on working memory in relation to age was further supported by neuroimaging studies (Haller et al., 2013; Klaassen et al., 2013). Correspondingly, DTI study of the corpus callosum (CC), which described to hold a vital role in connecting and coordinating both hemispheres to ensure competent cognitive functions, also found compromised microstructure of the CC with low fractional anisotropy and high mean diffusivity, both of which are indications of reduced white matter integrity (Treble et al., 2013). doi: 10.1016/j.neuroimage.2016.12.022, Rodriguez Merzagora, A. C., Izzetoglu, M., Onaral, B., and Schultheis, M. T. (2014). This article seeks to present an up-to-date introductory overview of the realm of working memory by outlining several working memory studies from the psychological and neurosciences perspectives in an effort to refine and unite the scientific knowledge concerning working memory. 25, 46–59.
