Working memory multicomponent model outcomes in individuals with traumatic brain injury: Critical review and meta-analysis

Abstract Objective: Traumatic Brain Injury (TBI) often leads to cognitive impairments, particularly regarding working memory (WM). This meta-analysis aims to examine the impact of TBI on WM, taking into account moderating factors which has received little attention in previous research, such as severity of injury, the different domains of Baddeley’s multi-component model, and the interaction between these two factors, as well as the interaction with other domains of executive functions. Method: Following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, a systematic review and meta-analysis searched Google Scholar, PubMed, and PsycNET for studies with objective WM measures. Multiple meta-analyses were performed to compare the effects of TBI severity on different WM components. Twenty-four English, peer-reviewed articles, mostly cross-sectional were included. Results: TBI significantly impairs general WM and all Baddeley’s model components, most notably the Central Executive (d’ = 0.74). Severity categories, mild-moderate and moderate-severe, were identified. Impairment was found across severities, with “moderate-severe” demonstrating the largest effect size (d’ = 0.81). Individuals with moderate-severe TBI showed greater impairments in the Central Executive and Episodic Buffer compared to those with mild-moderate injury, whereas no such differences were found for the Phonological Loop and Visuospatial Sketchpad. Conclusions: These findings enhance our understanding of WM deficits in varying severities of TBI, highlighting the importance of assessing and treating WM in clinical practice and intervention planning.

A comparison of working memory abilities between children with intellectual disability with non-specific aetiology and children with Down syndrome in schools for intellectual development in Germany

Objectives The study compares the working memory performance of students with Down syndrome (DS) to that of matched controls with non-specific intellectual disability (NSID). Even though empirical evidence is somewhat mixed and inconclusive, previous research suggests that students with DS display a relative weakness in the phonological loop. In contrast, no differences are reported in the visuo-spatial sketchpad and the central executive. Methods The sample consisted of 23 students with DS and 23 matched controls with NSID. The phonological loop was assessed using nonword repetition and picture span. Measures of the visuo-spatial sketchpad included a corsi-block task and a pattern span. Finally, an odd-one-out task was used to assess the executive-loaded working memory (ELWM) as a part of the central executive. Results Supporting our hypotheses, students with DS significantly differed from their peers with NSID in the phonological loop, while we found no performance differences for the visuo-spatial sketchpad and the ELWM. Conclusions Weaknesses in the phonological loop in students with DS are documented in literature and supported by this study. Important conclusions can be drawn for teachers’ instruction and students’ reading development. However, the study’s limitations mean that any inferences must be drawn cautiously.

Association between working memory performance and parent and teacher ratings of working memory in 11-year-old children born preterm

ABSTRACT Working memory (WM) difficulties are often observed in children born preterm. We examined whether performance-based measures of WM components are associated with parent- and teacher-rated WM difficulties in the everyday life of children born very preterm and/or at very low birth weight (VPT/VLBW) at 11 years (n = 165). The WM components as defined in the original Baddeley’s model – phonological loop (PL), visuospatial sketchpad (VS), and central executive (CE) – were assessed with tasks from the Working Memory Test Battery for Children (WMTB-C) and the Wechsler Intelligence Scale for Children – Fourth edition (WISC-IV). Parents and teachers completed the WM subscale of the Behavioral Rating Inventory for Executive Functions (BRIEF). Measures of WM components were modestly associated with BRIEF scores, explaining 18.9% of the variance in parent-rated and 14.0% of teacher-rated WM difficulties. CE was the component most consistently associated with parent- and teacher-rated everyday WM. To conclude, our results suggest that tasks that utilize CE functions may best reflect WM outside of controlled test settings in the follow-up of VPT/VLBW children. However, performance and rating-scale measures provide unique information and are both needed to comprehensively assess WM skills.

A - 37 ADHD-Related Hyperactivity and Impulsivity: Distinct or Overlapping Dimensions?

Abstract Objective It is debated whether hyperactivity and impulsivity should remain combined within the (DSM) hyperactivity/impulsivity domain or be separated. To address this dispute, we sought to determine whether hyperactivity and impulsivity are differentially related to executive functioning (EF), a common deficit area in ADHD. Method Participants included 120 children (ages 8–11; 89.9% White; 51.6% girls) from a community sample tested in a laboratory setting. To be included, they must have ADHD (59.4%) or be typically developing (40.6%). Hyperactivity and impulsivity scales were created from symptoms from a parent-report Behavior Assessment System for Children and DSM-IV questionnaire, ADHD section. The Behavior Rating Inventory of Executive Functioning (BRIEF) Working Memory scale (WMsc) and the Children’s Memory Scale Picture Locations (visuospatial sketchpad), Numbers Forward (phonological loop), and Sequences (central executive) subtests were used to assess working memory (WM). Inhibition was assessed with the BRIEF Inhibition scale (Isc) and A Developmental Neuropsychological Assessment (NEPSY) Tower Rule Violations (RV). Emotional control (EC) was measured with the BRIEF’s EC scale. Results Confirmatory linear regressions (SPSS Enter method) with all EF measures as IVs revealed Isc and WMsc were significant predictors of impulsivity [F(7,120) = 24.85, p < 0.001]. For hyperactivity [F(7,120) = 21.40, p < 0.001], WMsc, Isc, and RV were significant predictors. Exploratory analyses revealed WMsc was related to hyperactivity in controls but impulsivity in ADHD. Conclusions Similarities and differences were found between hyperactivity and impulsivity in relation to EF. Whereas inhibition was similarly related to hyperactivity and impulsivity, WM’s relationships were dissociable between groups. Hence, further research is needed, including areas affected in ADHD besides EF.

The audiovisual competition effect induced by temporal asynchronous encoding weakened the visual dominance in working memory retrieval

ABSTRACT Converging evidence suggests a facilitation effect of multisensory interactions on memory performance, reflected in higher accuracy or faster response time under a bimodal encoding condition than a unimodal condition. However, relatively little attention has been given to the effect of multisensory competition on memory. The present study adopted an adaptive staircase test to measure the point of subjective simultaneity (PSS), combined with a delayed matched-to-sample (DMS) task to probe the effect of audiovisual competition during the encoding stage on subsequent unisensory retrieval. The results showed that there was a robust visual dominance effect and multisensory interference effect in WM retrieval, regardless of the subjective synchronous or subjective asynchronous audiovisual presentation. However, a weakened visual dominance effect was observed when the auditory stimulus was presented before the visual stimulus in the encoding period, particularly in the semantically incongruent case. These findings revealed that the prior-entry of sensory information in the early perceptual stage could affect the processing in the late cognitive stage to some extent, and supported the evidence that there is a persistent advantage for visuospatial sketchpad in multisensory WM.

Utility Prospect of the Working Memory Model in Whispered Interpreting - the Case Study in “Nanning Tour” at the 20th China-ASEAN Expo as an Example

This study examines whispered interpreting (WI), where interpreters translate spoken language in real-time at a soft volume. It underscores the Working Memory Model’s (WMM) utility in such tasks, which demand intense cognitive effort. A practical example from the 2023 China-ASEAN Expo showcases the model’s mechanisms enhancing interpreting efficiency. The phonological loop processes verbal information, the visuo-spatial sketchpad handles visual cues, and the episodic buffer consolidates complex data. Managed by the central executive, these elements collectively lighten the cognitive load and boost performance. The paper reveals WMM’s untapped potential, advocating for deeper investigation into its application in WI.

Can Brief Listening to Mozart's Music Improve Visual Working Memory? An Update on the Role of Cognitive and Emotional Factors.

The aim of this research was to enhance understanding of the relationship between brief music listening and working memory (WM) functions. The study extends a previous large-scale experiment in which the effects of brief exposure to music on verbal WM were explored. In the present second phase of the experiment, these effects were assessed for the visuospatial subcomponent of WM. For that aim, visuospatial WM was measured using the Corsi blocks task-backwards and Visual Patterns Test in a large sample of 311 young and older adults after being exposed to musical excerpts coming from different music composers (Mozart, Vivaldi, Glass). To account for possible effects of arousal, a silence condition was used. Individual preference for music excerpts and emotional reactions to each condition were also subjectively rated using the Positive and Negative Affect Schedule (PANAS) to account for the role of emotional reactions in shaping subsequent cognitive performance. Results showed that music affected the visuospatial sketchpad of WM. In line with the previously described Mozart effect, only Mozart's music had a significant positive impact on visuospatial WM in the two age groups, regardless of preferences, and on overall age-related WM decline in older adults. The Mozart effect was more prominent for the VPT than the Corsi task and was also expressed for the prevailing positive effect. These observations are in contrast to the selective influence of Vivaldi's music on verbal WM that was detected in our first study. Together, the results demonstrate a differential music influence on the phonological loop and on the visuospatial sketchpad. They thus contribute to the debate of whether music has the potential to affect distinct processes within working memory in an excerpt- or composer-specific manner. Also, they suggest that emotional activation and central executive attention are essentially involved in modulating the influence of music on subsequent cognition. These findings can assist in the selection of music excerpts used in cognitive rehabilitation programs that focus on visuospatial skills.

Alpha neurofeedback training improves visual working memory in healthy individuals.

Neurofeedback (NF) training is a closed-loop brain training in which participants learn to regulate their neural activation. NF training of alpha (8-12 Hz) activity has been reported to enhance working memory capacity, but whether it affects the precision in working memory has not yet been explored. Moreover, whether NF training distinctively influences performance in different types of working memory tasks remains unclear. Therefore, the present study conducted a randomized, single-blind, sham-controlled experiment to investigate how alpha NF training affected the capacity and precision of working memory, as well as the related neural change. Forty participants were randomly and equally assigned to the NF group and the sham control group. Both groups received NF training (about 30 min daily) for five consecutive days. The NF group received alpha (8-12 Hz) training, while the sham control group received sham NF training. We found a significant alpha increase within sessions but no significant difference across sessions. However, the behavioral performance and neural activity in the modified Sternberg task did not show significant change after alpha NF training. On the contrary, the alpha NF training group significantly increased visual working memory capacity measured by the Corsi-block tapping task and improved visual working memory precision in the interference condition in a color-recall task. These results suggest that alpha NF training influences performance in working memory tasks involved in the visuospatial sketchpad. Notably, we demonstrated that alpha NF training improves the quantity and quality of visual working memory.

Examining the role of the visuospatial sketchpad in children's math calculation skills using Baddeley and Hitch's model of working memory

Math difficulties (MDs) occur in about 3–7 % of children and have been associated with academic, health, and occupational challenges. To date, findings about the role of working memory in MDs have been conflicting. The Automated Working Memory Assessment Battery (AWMA), which assesses all components of Baddeley and Hitch's model of working memory, was used to investigate which component of the model was most related to math calculation skills in elementary-school children. Participants were 94 (52 male) children (M age = 9 years 1 month; Range = 6 years 0 months to 11 years 8 months). As hypothesized, math calculation scores were correlated with all four working memory components (phonological loop, visuospatial sketchpad, verbal and visuospatial central executive). After accounting for age, phonological processing, and attention, the visuospatial sketchpad was the only memory component that contributed to the prediction of math calculation scores, explaining an additional 10.2 % of unique variance. Short-term visuospatial memory should be assessed in children having difficulty with math and children could benefit from interventions that include attention to the development of both visuospatial memory and math calculation skills. This study did not use a longitudinal design and so we cannot conclude that weak visuospatial memory impedes the development of math calculation skills. Future research should use longitudinal designs and investigate other types of math skills.

No role of working memory in the relation between mental rotation and postural stability

This study investigated the relationship between mental rotation ability and postural stability, with a focus on the role of the visuospatial sketchpad of working memory, as it has been found to be correlated with both concepts. A total of 87 healthy young adults completed a postural stability task on a force plate, a mental rotation task, and both spatial and object working memory tasks in a counterbalanced order. Bayesian correlations revealed weak positive correlations between mental rotation and postural stability, as well as a correlation between mental rotation and spatial working memory. A weak association was also observed between mental rotation and object working memory. No correlation was found between the working memory components and postural stability. Furthermore, the results showed that spatial working memory did not play a crucial role in predicting postural stability. We conclude that the visuospatial sketchpad, particularly the spatial working memory component, cannot explain the relationship between mental rotation and postural stability.

New Working Memory Paradigm for Neuroimaging Testing of Visual and Verbal Modality under Different Attentional Involvement

Working memory (WM) is a cognitive function essential for short-term maintenance of information in a highly accessible state to support goal-directed behavior. The classical behavioral model of WM includes a visuospatial sketchpad, a phonological loop and the central executive. Neuroimaging studies selectively targeted the activity associated with maintenance and processing of modality specific information. However, an experimental design is still missing that would enable the assessment of all components of WM drawing a holistic neuroimaging model. In this study, we propose a modified paradigm based on the classical retro-cue task, which allows disentangling the activity of all WM components, and in particular of the central executive. This paradigm consists of five conditions: passive perception, simple verbal storage, simple visual storage, alphabetical reordering (complex verbal) and mental rotation (complex visual). Testing on a cohort of 35 healthy adults, we obtained a similar workload for simple storage conditions with a low engagement of the central executive. A different workload was verified between the simple and complex conditions in both verbal and visual modalities. This experimental design provides the framework to assess the neural activity associated with the central executive components in different modalities and to address the question of a unitary or modality-specific central executive nature. Therefore, the paradigm is suitable for utilization in neuroimaging to potentially advance our comprehension of the WM organization.

Neuropsychological Assessment of the Relationship of Working Memory with K-BIT Matrices and Vocabulary in Normal Development and ADHD Children and Adolescents.

The present report tries to understand the possible relationship between working memory (WM) and intelligence measurements, using the direct scores of the Working Memory Test Battery for Children (WMTBC) and Kaufman's Brief Intelligence Test (K-BIT), in normal development (ND) and diagnosed attention deficit hyperactivity disorder (ADHD) children and adolescents. Partial correlations, discounting the effect of age, showed a significant correlation in ND subjects between the central executive (CE) component of WM and the WM visuospatial sketchpad (VSS) component and the WM phonological loop (PL); also, significant correlations were obtained for the WM VSS with the K-BIT Matrices scores, the WM PL with the K-BIT Vocabulary, and the K-BIT Matrices scores with the K-BIT Vocabulary. For ADHD subjects, there were significant correlations between WM VSS and WM CE, and WM VSS and K-BIT Matrices. We tested the robustness of these correlations by selecting a small number of subjects through permutations; a robust correlation between WM CE and WM PL in ND, and between WM VSS and WM CE and WM VSS and K-BIT Matrices scores was obtained. These results were also supported by mediation analysis. There is a relationship during development between WM as measured with WMTBC and general intelligence as measured with K-BIT in ND and ADHD subjects. The dysexecutive character of ADHD has been shown, given that by controlling for intelligence, the differences in WM performance between ND and ADHD disappear, except for WM CE. The results suggest that in ADHD subjects, the WM VSS component presents a more pivotal role during cognitive processing compared to ND subjects.

Exploring the relationship between workplace bullying and objective cognitive performance

ABSTRACT In two studies, we investigated the effects of workplace bullying on objective measures of cognitive functioning. In Study 1, 47 university employees, self-identified as current targets of bullying (n = 24) or non-targets (n = 23), completed objectively scored cognitive tasks assessing general attention and three components of working memory (central executive, visuospatial sketchpad, and phonological loop). T-test analyses showed that self-identified targets performed more poorly on the suite of tests compared to non-bullied counterparts, primarily driven by deficits in central executive functioning. Study 2 recruited 70 retail and hospitality workers who completed the cognitive tasks plus measures of preoccupying cognitions and exposure to negative acts. As hypothesised, we found significant indirect effects demonstrating that preoccupying cognitions explained the negative relationship between bullying and the three aspects of working memory. The magnitude of the cognitive deficits observed here, and their potential significance for job performance, highlights the importance of primary bullying prevention within organisations. Secondary and tertiary prevention efforts should also consider cognitive impairments experienced by targets and look for opportunities to reduce preoccupying cognitions, which compete for limited cognitive resources, to mitigate the erosive effects of bullying.

The Relationship between Linguistic Disfluencies and Cognitive Abilities in School-aged Children with and without Vocabulary Delay

Objectives: This study aimed to examine the characteristics of linguistic disfluencies during story generation and retelling tasks and to investigate an association between linguistic disfluencies and cognitive abilities in narrative samples. Methods: A total of 49 children aged 7-10 (20 children with vocabulary delay and 29 typically developing children) participated. Participants completed the story generation and retelling task. Children’s utterances were analyzed into four categories of mazes: fillers, repetitions, revisions, and pauses. Participants also completed three working memory tasks that assess phonological loop, episodic buffer, and visuospatial sketchpad. Results: First, both children with vocabulary delay and typically developing children produced a greater total number of utterances in the narrative retelling task than in the narrative generation task, and children with vocabulary delay showed higher rates of pauses. Also, children with VD showed a higher rate of pauses in the generation task than the TD group and higher rates of filled pauses, pauses, and the total number of mazes in the retelling task. For the TD group, expressive vocabulary was the best predictor for the use of mazes during a story-generation task, whereas receptive vocabulary was the best predictor for the use of mazes during a story-retelling task. Non-word repetition was a significant predictor in children with VD. Conclusion: Results showed children with vocabulary delay had higher mazes rates than typically developing peers. Also, different cognitive factors explained the linguistic disfluencies of the two groups. Results suggest that vocabulary and working memory need to be considered for interventions aimed at children’s fluent speech.

How are patterned movements stored in working memory?

In this study, the change detection paradigm was used to study the working memory of patterned movements and the relationship of this type of memory with the visuospatial sketchpad in three experiments. Experiment 1 measured participants' working memory capacity for patterned movements and explored the influence of stimulus type with indicators such as response time and accuracy rate. Experiments 2 and 3 explored the relationship between patterned movements and the visual and spatial subsystems, respectively. The results of Experiment 1 indicated that individuals can store 3-4 patterned movements in working memory; however, a change in stimulus format or an increase in memory load may decrease the speed and efficiency of working memory processing. The results of Experiment 2 showed that working memory and visual working memory are independent when processing patterned movements. The results of Experiment 3 showed that the working memory of patterned movements was affected by spatial working memory. Changes in stimulus type and memory load exerted different effects on the working memory capacity of participants. These results provide behavioral evidence that the storage of patterned movement information is independent of the visual subsystem but requires the spatial subsystem of the visuospatial sketchpad.

The logo ‘visual thickness effect’: When and why it boosts brand personality

AbstractAlthough the literature suggests that logos impart symbolic meanings via visual elements that influence consumers' early evaluation of brands, few such elements have been studied, with others (e.g., logo thickness) awaiting scholarly investigation. According to the literature, visual thickness seems to influence perception of power and consumers' consequent judgments. This research tests and theorises the influence of the logo visual thickness effect on consumer behaviour. Results of five studies employing more than 4000 MTurk participants and 20 fictitious logos suggest that thick logos boost perception of brand personality mediated by a pronounced perception of brand power. In addition, the logo‐thickness‐induced perception of brand power is negatively moderated by consumers' level of perceived power of the self. Further, the perception of brand power induced by logo thickness is moderated by consumers' level of visuospatial sketchpad, meaning that people with high (vs. low) visuospatial sketchpad can cancel out the extraneous influence of logo thickness while evaluating the underlying brand, once the stimulus magnitude hits the salience threshold. Theoretical and managerial implications are accordingly provided.

Working memory and consciousness:

The view of working memory as a conscious process has allowed to define consciousness as the content of working memory. However, concerns have emerged over comparisons between consciousness and working memory. Although the relationship between these two study fields has been the matter of psychology, philosophy and neuroscience, a theoretical review addressing the core elements of highly cited perspectives would enrich the discussion in this study area. This review focuses on three theoretical frameworks: 1) the multi-component model of working memory, 2) the global workspace theory, 3) the hierarchical framework. The multi-component model of working memory contributes a basic functional description on how mental representations remain on-line during complex cognitive processing. Thereby, the information exchange between the central executive and the episodic buffer, in one sense, and the phonological loop and the visuo-spatial sketchpad in the other is given trough conscious processing. Likewise, the central executive controls and changes attention but the episodic buffer allows multimodal information availability.

Effects of Auditory Pre-Stimulation on Cognitive Task Performance in a Noisy Environment

The accident rate due to human errors in industrial fields has been consistently high over the past few decades, and noise has been emerging as one of the main causes of human errors. In recent years, auditory pre-stimulation has been considered as a means of preventing human errors by improving workers’ cognitive task performance. However, most previous studies demonstrated the effectiveness of the auditory pre-stimulation in a quiet environment. Accordingly, studies on the effects of pre-stimulation in a noisy environment are still lacking. Therefore, this study aimed to empirically investigate: (1) the effects of noisy environments on the performances of cognitive tasks related to different functions of working memory and (2) the effects of auditory pre-stimulation on the performances of cognitive tasks in a field-noise environment. To accomplish these research objectives, two major experiments were conducted. In the first experiment, a total of 24 participants performed each of three basic short-term/working memory (STM/WM) tasks under two different experimental conditions (quiet-noise environment and field-noise environment) depending on the presence or absence of field noise. In the second experiment, the participants performed each of the three basic STM/WM tasks in a field-noise environment after they were provided with one of four different auditory pre-stimulations (quiet noise, white noise, field noise, and mixed (white and field) noise). The three STM/WM tasks were the Corsi block-tapping, Digit span, and 3-back tasks, corresponding to the visuospatial sketchpad, the phonological loop, and the central executive of WM, respectively. The major findings were that: (1) the field-noise environment did not affect the scores of the Corsi block-tapping and 3-back tasks, significantly affecting only the Digit span task score (decreased by 15.2%, p < 0.01); and (2) the Digit span task performance in the field-noise environment was improved by 17.9% (p < 0.05) when mixed noise was provided as a type of auditory pre-stimulation. These findings may be useful for the work-space designs that prevent/minimize human errors and industrial accidents by improving the cognitive task performance of workers in field-noise environments.

Information Processing and Memory in Learning

ABSTRACT
 The success of learning is strongly influenced by information processing mechanisms and working memory. The characteristics of the initial information will affect the sensory response which is continued by storage in sensory memory. Various stimulus information such as psychophysical stimulus, emotional stimulus, discrepant stimulus and manding stimulus will have an effect on the response back from respondents. Information will be selected to enter short term memory (STM) through a working memory mechanism with the ability to store information within a few seconds. Working memory is managed by the Central executive control center by involving the phonological Loop area, Episode buffer, and Visuo-spatial Sketch Pad. Then the information is continued to Long Term Memory (LTM) with repetition and coding mechanism. Long-term memory storage in the area of ??episodic memory, semantic memory and procedural memory. Working memory is influenced by cognitive load (Cognitive Load) and Cognitive Fit Theory (CFT).

The effect of backpack weight on the performance of basic short-term/working memory tasks while walking along a pre-determined route

This study investigated possible backpack weight effects on the performance of three basic short-term/working memory (STM/WM) tasks conducted concurrently with the physical task of route walking. The STM/WM tasks were the Corsi block-tapping, digit span, and 3-back tasks, and, were employed to examine the visuo-spatial sketchpad, phonological loop and central executive components of the WM system. Four backpack weight levels (0%, 15%, 25% and 40% of body mass) were considered. Thirty participants conducted the three experimental tasks requiring physical-cognitive multitasking. Data analyses revealed that: (1) increased backpack weight resulted in decreases in the performance of the Corsi block-tapping and the 3-back task, but (2) backpack weight did not significantly affect the digit span task performance. The study results suggest that reducing backpack weight could benefit the performance of various cognitive tasks during route walking. The study findings may be useful for the ergonomics design of body-worn equipment and human-system interfaces. Practitioner summary: This study examined the backpack weight effects on the performance of three basic short-term/working memory tasks conducted concurrently with the physical task of route walking. The study revealed that reducing backpack weight could benefit various cognitive tasks during physical-cognitive multitasking, especially cognitive tasks that require visuospatial processing and executive control.
