Cognitive Modulation Research Articles

Distinct septo-hippocampal cholinergic projections separately mediate stress-induced emotional and cognitive deficits.

Patients suffering from chronic stress develop numerous symptoms, including emotional and cognitive deficits. The precise circuit mechanisms underlying different symptoms remain poorly understood. We identified two distinct basal forebrain cholinergic subpopulations in mice projecting to the dorsal hippocampus (dHPC) or ventral hippocampus (vHPC), which exhibited distinct input organizations, electrophysiological characteristics, transcriptomics, and responses to positive and negative valences of stimuli and were critical for cognitive and emotional modulation, respectively. Moreover, chronic stress induced elevated anxiety levels and cognitive deficits in mice, accompanied by enhanced vHPC but suppressed dHPC cholinergic projections. Chemogenetic activation of dHPC or inhibition of vHPC cholinergic projections alleviated stress-induced aberrant behaviors. Furthermore, we identified that the acetylcholinesterase inhibitor donepezil combined with blockade of muscarinic receptor 1-type muscarinic acetylcholine receptors in the vHPC rescued both stress-induced phenotypes. These data illuminated distinct septo-hippocampal cholinergic circuits mediated specific symptoms independently under stress, which may provide promising strategies for circuit-based treating of stress-related psychiatric disorders.

Effectiveness of Virtual - Compensatory Cognitive Training (V-CCT) for improving cognition in persons with schizophrenia - a multi- centre randomized controlled trial

BackgroundCognitive deficits are the core component in persons with schizophrenia which impacts their socio-occupational functioning. Also, cognitive deficits cause significant impairment with the person’s quality of life [3]. Hence, targeting such a pivotal aspect in persons with schizophrenia through suitable interventions is very important. Developed countries have designed various cognitive remediation programs using computers involving high-end software which cannot be generalized to low-resource settings, like India, due to various factors including sociocultural factors, educational standards, and living standards of the patient population. Compensatory cognitive training (CCT) was developed to be “brief, practical, low-tech” and found to be effective in the west [9]. As there are no structured cognitive intervention modules in India, we have adapted the English CCT manual to be used for an urban population in Chennai, India. CCT was found to be feasible in face-to-face group sessions in our setting [12] and is found to be feasible and acceptable as virtual one–one intervention (unpublished data). Therefore, this study aims to evaluate the effectiveness of V-CCT in enhancing cognition and socio-occupational functioning.MethodsThe proposed study will be a multicenter assessor-blinded randomized controlled trial at two clinical sites in Chennai, India. The preparatory phase of the study would include translation of the manual to the local language, recruitment and training of research assistants, and pilot testing using the translated manual. The second phase will be the main randomized controlled trial (RCT), during which a total of 160 persons diagnosed with schizophrenia will be recruited from both sites. After obtaining informed consent, baseline assessments will be conducted on cognition, functioning, self-esteem, and quality of life. Participants will be randomly assigned to either the virtual CCT group or the control group using a computer-generated randomization table. End-line assessments will be conducted 6 weeks after the baseline by research assistants who are blinded to the randomization post-intervention.DiscussionIf V-CCT is found to be effective, it will be available for use in Tamil for persons with schizophrenia, and it will have an effect on their functioning, quality of life, and self-esteem.Trial registrationThe study is registered under Clinical trial registry-India (CTRI), and the registration number is CTRI/2024/04/065267. Registered on April 2024.

The effect of covert visual attention on pupil size during perceptual fading

Pupil size is modulated by various cognitive factors such as attention, working memory, mental imagery, and subjective perception. Previous studies examining cognitive effects on pupil size mainly focused on inducing or enhancing a subjective experience of brightness or darkness (for example by asking participants to attend to/ memorize a bright or dark stimulus), and then showing that this affects pupil size. Surprisingly, the inverse has never been done; that is, it is still unknown what happens when a subjective experience of brightness or darkness is eliminated or strongly reduced even though bright or dark stimuli are physically present. Here, we aim to answer this question by using perceptual fading, a phenomenon where a visual stimulus gradually fades from visual awareness despite its continuous presentation. The study contains two blocks: Fading and Non-Fading. In the Fading block, participants were presented with black and white patches with a fuzzy outline that were presented at the same location throughout the block, thus inducing strong perceptual fading. In contrast, in the Non-Fading block, the patches switched sides on each trial, thus preventing perceptual fading. Participants covertly attended to one of the two patches, indicated by a cue, and reported the offset of one of a set of circles that are displayed on top. We hypothesized that pupil size will be modulated by covert visual attention in the Non-Fading block, but that this effect will not (or to a lesser extent) arise in the Fading block. We found that covert visual attention to bright/ dark does modulate pupil size even during perceptual fading (Fading block), but to a lesser extent than when the perceptual experience of brightness/ darkness is preserved (Non-Fading block). This implies that pupil size is always modulated by covert attention, but that the effect decreases as subjective experience of brightness or darkness decreases. In broader terms, this suggests that cognitive modulations of pupil size reflect a mixture of high-level and lower-level visual processing.

Increased functional connectivity between brain regions involved in social cognition, emotion and affective-value in psychedelic states induced by N,N-Dimethyltryptamine (DMT).

The modulation of social cognition is suggested as a possible mechanism contributing to the potential clinical efficacy of psychedelics in disorders involving socio-emotional and reward processing deficits. Resting-state functional Magnetic Resonance Imaging (rs-fMRI) can be used to detect changes in brain connectivity during psychedelic-induced states. Thus, this pharmacoimaging study investigates the effects of N,N-Dimethyltryptamine (DMT) on functional connectivity in brain areas relevant to social cognition, using a within-subject design in eleven healthy experienced users. The study included both an active and a control condition, conducted at different time points. The active condition involved DMT inhalation, while the control condition did not. Seed-based connectivity was measured for the two core regions involved in theory of mind and emotional processing, respectively, the posterior supramarginal gyrus and the amygdala. DMT increased supramarginal gyrus connectivity with the precuneus, posterior cingulate gyrus, amygdala, and orbitofrontal cortex. Additionally, increased connectivity emerged between the amygdala and orbitofrontal cortex. These results demonstrate that DMT modulates brain connectivity in socio-emotional and affective-value circuits, advancing our understanding of the neural mechanisms underlying the psychedelic experience and its potential therapeutic action.

Semi‐supervised contextual cognitive augmentation‐based cross‐teaching network for multiclass medical image segmentation

AbstractThe application of medical image segmentation technology enables accurate localization of human tissues, providing doctors with a reliable foundation for diagnosis. While deep learning methods have proven effective in this task, most current approaches rely on a single prediction framework, which overlooks Edge semantic features and results in flawed texture features. Moreover, existing supervised methods face challenges due to limited availability of high‐quality annotations in the field of medical imaging. In this article, a Semi‐supervised Contextual Cognitive Augmentation‐based Cross‐teaching Network is proposed. A Contextual Cognitive Enhancement Module is introduced consisting of two components: data augmentation and information extraction. The data augmentation component provides multi‐level data distribution by incorporating diverse perturbation strategies such as Discrete Cosine Transform and Gaussian noise. The information extraction component employs the Comprehensive Information Extraction module, which consists of Global Perception Information Extraction module and Multi‐channel Information Extraction module to extract perceptual information from images and enhance interaction between image channels, respectively. Additionally, a cross‐teaching strategy is adopted and a hybrid loss function is utilized to encourage knowledge sharing among the networks, leveraging the advantages of dual networks for improved performance. Experimental results demonstrate significant enhancements in multiclass medical image segmentation compared to several state‐of‐the‐art single‐framework networks.

Slow-Paced Breathing Intervention in Healthcare Workers Affected by Long COVID: Effects on Systemic and Dysfunctional Breathing Symptoms, Manual Dexterity and HRV.

Many COVID-19 survivors still experience long-term effects of an acute infection, most often characterised by neurological, cognitive and psychiatric sequelae. The treatment of this condition is challenging, and many hypotheses have been proposed. Non-invasive vagus nerve stimulation using slow-paced breathing (SPB) could stimulate both central nervous system areas and parasympathetic autonomic pathways, leading to neuromodulation and a reduction in inflammation. The aim of the present study was to evaluate physical, cognitive, emotional symptoms, executive functions and autonomic cardiac modulation after one month of at-home slow breathing intervention. 6655 healthcare workers (HCWs) were contacted via a company email in November 2022, of which N = 58 HCWs were enrolled as long COVID (cases) and N = 53 HCWs as controls. A baseline comparison of the two groups was performed. Subsequently each case was instructed on how to perform a resonant SPB using visual heart rate variability (HRV) biofeedback. They were then given a mobile video tutorial breathing protocol and asked to perform it three times a day (morning, early afternoon and before sleep). N = 33 cases completed the FU. At T0 and T1, each subject underwent COVID-related, psychosomatic and dysfunctional breathing questionnaires coupled with heart rate variability and manual dexterity assessments. After one month of home intervention, an overall improvement in long-COVID symptoms was observed: confusion/cognitive impairment, chest pain, asthenia, headache and dizziness decreased significantly, while only a small increase in manual dexterity was found, and no relevant changes in cardiac parasympathetic modulation were observed.

New insights into individual differences in response to chronic unpredictable mild stress (CUMS) in rats with respect to hippocampal BDNF and GSK3-β expression levels

Preclinical and clinical studies have shown a wide-range of individual differences in response to stressors or novel environments which can affect the susceptibility to develop abnormal behaviors and neuropsychiatric disorders. Both vulnerability and resiliency have been observed in animals and humans experiencing stressful events. Chronic unpredictable mild stress (CUMS) is a rodent depression model consisting of various stressors. This protocol leads to depressive- and anhedonic-like behaviors in rodents. The present study aimed to evaluate potential individual differences in response to CUMS in rats, with respect to the expression level of brain-derived neurotrophic factor (BDNF) and glycogen synthase kinases 3-beta (GSK3-β) (proteins involved in the modulation of mood, neuroplasticity, and cognition) in the hippocampus. CUMS was performed for four consecutive weeks. Depressive-like behavior, locomotor activity, anxiety-like behavior, and pain threshold were also evaluated using forced swim test (FST), open field test (OFT), and the hot plate (HP), respectively. Real-time PCR was used to evaluate BDNF and GSK3-β expression levels. The results showed that CUMS rats can be classified as two clusters: affected and non-affected (depressed and non-depressed). Affected rats showed depressive- and anxiety-like behaviors, decreased locomotor activity, and increased pain threshold. However, non-affected rats were similar to controls. In addition, there was a downregulation of BDNF and upregulation of GSK3-β in affected rats. Spearman correlation analysis also showed a relationship between BDNF and GSK3-β expression levels with individual differences. In conclusion, the present study showed that BDNF and GSK3-β may be involved in individual differences in CUMS rats.

Synaptophysin and GSK-3beta activity in the prefrontal cortex may underlie the effects of REM sleep deprivation and lithium on behavioral functions and memory performance in male rats

Rapid-eye movement (REM) stage of sleep serves a critical role in processing cognitive and behavioral functions. Evidence shows that REM sleep deprivation (REM SD) strongly affects the mood state and cognitive abilities. However, there are many inconsistent reports. Although the exact molecular mechanisms underlying REM SD effects have not well been discovered, however, molecular factors including those affected synaptic plasticity and mood state may be involved. There are two important molecular factors that have not been well studied: synaptophysin and glycogen synthase kinase-3 beta (GSK-3beta). The present study aimed to investigate the role of synaptophysin and GSK-3beta in the modulation of memory and behavioral changes induced by REM SD and lithium (as a potent GSK-3beta inhibitor and mood stabilizer). Multiple platform apparatus was used to induce REM SD for 48 h. Lithium was injected at the dose of 50 mg/kg, intraperitoneal (i.p.). Locomotor activity, anxiety-like behavior, pain threshold, novel object recognition memory, and synaptophysin and GSK-3beta level in the prefrontal cortex were evaluated. Results showed REM SD increased locomotor activity, decreased pain threshold, impaired novel object recognition memory, decreased synaptophysin and increased GSK-3beta levels. Lithium reversed these effects. Anxiety-like behavior was unaffected. For the first time, the present study showed that GSK-3beta and synaptophysin may be involved in the modulation of behavior and cognition induced by REM SD and lithium. In conclusion, we suggested that GSK-3beta upregulation and synaptophysin downregulation may underlie the deleterious effects of REM SD, while lithium may counteract REM SD effects via restoring the level of both.

Dopamine-mediated formation of a memory module in the nucleus accumbens for goal-directed navigation.

Spatial memories guide navigation efficiently toward desired destinations. However, the neuronal and circuit mechanisms underlying the encoding of goal locations and its translation into goal-directed navigation remain unclear. Here we demonstrate that mice rapidly form a spatial memory of a shelter during shelter experiences, guiding escape behavior toward the goal location-a shelter-when under threat. Dopaminergic neurons in the ventral tegmental area and their projection to the nucleus accumbens (NAc) encode safety signals associated with the shelter. Optogenetically induced phasic dopamine signals are sufficient to create a place memory that directs escape navigation. Converging dopaminergic and hippocampal glutamatergic inputs to the NAc mediate the formation of a goal-related memory within a subpopulation of NAc neurons during shelter experiences. Artificial co-activation of this goal-related NAc ensemble with neurons in the dorsal periaqueductal gray was sufficient to trigger memory-guided, rather than random, escape behavior. These findings provide causal evidence of cognitive circuit modules linking memory with goal-directed action.

Effects of four-week intranasal oxytocin administration on large-scale brain networks in older adults

Oxytocin (OT) is a crucial modulator of social cognition and behavior. Previous work primarily examined effects of acute intranasal oxytocin administration (IN-OT) in younger males on isolated brain regions. Not well understood are (i) chronic IN-OT effects, (ii) in older adults, (iii) on large-scale brain networks, representative of OT's wider-ranging brain mechanisms. To address these research gaps, 60 generally healthy older adults (mean age = 70.12 years, range = 55–83) were randomly assigned to self-administer either IN-OT or placebo twice daily via nasal spray over four weeks. Chronic IN-OT reduced resting-state functional connectivity (rs-FC) of both the right insula and the left middle cingulate cortex with the salience network but enhanced rs-FC of the left medial prefrontal cortex with the default mode network as well as the left thalamus with the basal ganglia–thalamus network. No significant chronic IN-OT effects were observed for between-network rs-FC. However, chronic IN-OT increased selective rs-FC of the basal ganglia–thalamus network with the salience network and the default mode network, indicative of more specialized, efficient communication between these networks. Directly comparing chronic vs. acute IN-OT, reduced rs-FC of the right insula with the salience network and between the default mode network and the basal ganglia–thalamus network, and greater selective rs-FC of the salience network with the default mode network and the basal ganglia–thalamus network, were more pronounced after chronic than acute IN-OT. Our results delineate the modulatory role of IN-OT on large-scale brain networks among older adults.

Enhancing cognitive performance and mitigating dyslipidemia: the impact of moderate aerobic training on sedentary older adults

BackgroundThe present study aimed to evaluate the effects of 24 weeks of moderate aerobic exercise on lipids and lipoprotein levels; Lipo (a) markers, and their association with cognitive performance in healthy older adults.MethodsA total of 150 healthy subjects (100 males and 50 females; age range: 65–95 years) were recruited for this study. Based on the LOTCA test score, subjects were classified into two groups: the control group (n = 50) and the cognitive impairment group (n = 100). Cognitive functioning, leisure-time physical activity (LTPA), lipid profile, total cholesterol, TG, HDL-c, LDL-C, and lipo(a) were assessed at baseline and post-24-week aerobic exercise interventions using LOTCA battery, pre-validated Global Physical Activity Questionnaire (GPAQ) version II, colorimetric, and immunoassay techniques, respectively.ResultsSignificant improvements in cognitive function and modulation in lipid profile and lipoprotein (a) markers were reported in all older subjects following 24 weeks of moderate exercise. LOTCA-7-sets scores significantly correlated with physical activity status and the regulation of lipids and Lipo (a) markers. Physically active persons showed higher cognitive performance along with a reduction in the levels of T-Cholest., TG, LDL-C, Lipo (a), and an increase in the levels of HDL-C and aerobic fitness VO2max compared with sedentary participants. Cognitive performance correlated positively with increased aerobic fitness, HDL-C, and negatively with T-Cholest., TG, LDL-C, and Lipo (a). However, a significant increase in the improvement of motor praxis, vasomotor organization, thinking operations, attention, and concentration were reported among older adults.ConclusionsThe study findings revealed that supervised moderate aerobic training for 24 weeks significantly enhances cognitive functions via mitigating older adults’ lipid profiles and lipoprotein (a). Cognitive performance is positively correlated with aerobic fitness and HDL-C level and negatively with T-Cholest., TH, LDL-C, and Lipo (a).

Cognitive reserve as a modulator of cognitive decline and of behavioral symptoms in patients with amyotrophic lateral sclerosis

Introduction: Amyotrophic lateral sclerosis (ALS) has heterogeneous manifestations ranging from motor neuron degeneration to cognitive and behavioral impairment. This study aims to clarify the interactions between cognition and behavioral symptoms with relevant disease predictors and with cognitive reserve (CR), quantified through education, physical activity, and occupation proxies. Methods: A prospective sample of 162 ALS patients and 61 controls were evaluated with the Edinburgh Cognitive and Behavioral ALS Screen (ECAS) (dependent variable), a Cognitive Reserve Index questionnaire (CRIq) and demographic data (age and sex), and, for patients, clinical variables: disease duration, site of onset, the ALS Functional Rating Scale (ALSFRS), forced vital capacity (FVC), and gene mutation chromosome 9 open reading frame 72 (C9orf72) (independent variables). Multiple regression and mediation analyses were performed to predict cognitive and behavioral symptoms. Results: For the ALS group, the statistical model explained 38.8% of variance in ECAS total (p < 0.001), 59.4% of executive functions (p < 0.001), and 55% of behavioral symptoms (p < 0.001). For controls, it accounted for 52.8% of variance in ECAS total (p < 0.001). Interaction effects and mediation analysis showed CR is an ECAS total modulator, with a differential effect within groups (p < 0.001). Verbal fluency was the single best cognitive score to differentiate patients from controls (p = 0.004), and the gene mutation C9orf72 was found to be a behavioral symptom’ predictor in patients (p = 0.009). Conclusion: This study supports the proposed concept that CR acts as a cognitive modulator in ALS patients and healthy individuals. Moreover, CR also modulates behavioral manifestations in ALS.

Neural circuit basis of placebo pain relief.

Placebo effects are notable demonstrations of mind-body interactions1,2. During pain perception, in the absence of any treatment, an expectation of pain relief can reduce the experience of pain-a phenomenon known as placebo analgesia3-6. However, despite the strength of placebo effects and their impact on everyday human experience and the failure of clinical trials for new therapeutics7, the neural circuit basis of placebo effects has remained unclear. Here we show that analgesia from the expectation of pain relief is mediated by rostral anterior cingulate cortex (rACC) neurons that project to the pontine nucleus (rACC→Pn)-a precerebellar nucleus with no established function in pain. We created a behavioural assay that generates placebo-like anticipatory pain relief in mice. In vivo calcium imaging of neural activity and electrophysiological recordings in brain slices showed that expectations of pain relief boost the activity of rACC→Pn neurons and potentiate neurotransmission in this pathway. Transcriptomic studies of Pn neurons revealed an abundance of opioid receptors, further suggesting a role in pain modulation. Inhibition of the rACC→Pn pathway disrupted placebo analgesia and decreased pain thresholds, whereas activation elicited analgesia in the absence of placebo conditioning. Finally, Purkinje cells exhibited activity patterns resembling those of rACC→Pn neurons during pain-relief expectation, providing cellular-level evidence for a role of the cerebellum in cognitive pain modulation. These findings open the possibility of targeting this prefrontal cortico-ponto-cerebellar pathway with drugs or neurostimulation to treat pain.

"Why (Zebra)fish May Get Ulcers": Cognitive and Social Modulation of Stress in Fish.

In the bestseller book "Why Zebras Don't Get Ulcers", Robert Sapolsky argues that animals do not suffer from stress-related diseases like humans because for them, stress is episodic, while humans in contrast suffer from chronic psychological stress. In particular, the idea that fish cannot experience psychological stress is still prevalent, partly due to the lack of a homologous brain area to the neocortex. However, emerging evidence suggests that teleosts can undergo psychological stress, defined as a subjective and perceptual experience of the stressor, and in recent years, the underlying mechanisms started to be unveiled. The occurrence of cognitive appraisal in the assessment of stressors has been demonstrated in fish, indicating that the subjective evaluation of stimulus valence and salience, rather than absolute intrinsic characteristics of the stimulus itself, play a key role in the activation of the stress response. Moreover, individual biases (i.e., cognitive bias) in the cognitive appraisal of stimuli have also been described in fish, with some individuals consistently evaluating ambiguous stimuli as positive (aka optimists) whereas other individuals (aka pessimists) appraise them as negative. As a result, optimists and pessimists show consistent differences in stress reactivity and susceptibility/resilience to disease. Finally, social context has also been shown to modulate the response to aversive stimuli with the behavior of conspecifics either buffering or enhancing the response (i.e., social buffering vs. social contagion). Cognitive appraisal of stressors occurs in fish, implying that the stress response is modulated by a subjective and perceptual experience of the stressor. Moreover, interindividual consistent cognitive biases in the appraisal of stressors are also present in fish making some individuals more susceptible to stress-related diseases. Therefore, psychological stress has a health toll in fish, and psychologically stressed fish can potentially have ulcers.

Reducing intrusive suicidal mental images in patients with depressive symptoms through a dual-task add-on module: Results of a multicenter randomized clinical trial.

To examine the safety and efficacy of a brief cognitive dual-task (using eye movements) add-on module to treatment as usual (TAU) in reducing the severity and frequency of intrusive suicidal mental images and suicidal ideation. We conducted a single-blind, parallel multicenter randomized trial (No. NTR7563) among adult psychiatric outpatients (N = 91; Mage = 34.4, SD = 13.54; 68% female) with elevated depressive symptoms and experiencing distressing suicidal intrusions in the Netherlands. Primary outcome was the severity (Suicidal Intrusions Attributes Scale) and frequency (Clinical Interview for Suicidal Intrusions) of suicidal mental imagery intrusions at 1-week posttreatment and 3-month follow-up. Primary analysis was intention-to-treat. Between November 27, 2018 and September 13, 2021, 91 patients were included and randomly assigned to intervention group (Cognitive Dual Task Add-on + TAU) (n = 46) or TAU-only (n = 45). Cognitive Dual Task Add-on + TAU had greater reductions in severity (mean difference, -15.50, 95% CI [23.81, -7.19]; p < .001, d = 0.60), and frequency (geometric mean difference, 0.47, 95% CI [0.29, 0.79]; p = .004) of suicidal intrusions over time than TAU-alone. Cognitive Dual Task Add-on + TAU patients also showed lower suicidal ideation over time (p = .008, d = 0.42). There were no significant group differences in reductions in depressive symptoms, rumination, or hopelessness. Four serious adverse events occurred (three Cognitive Dual Task Add-on + TAU; one TAU-only); all unlikely attributable to intervention/trial. Findings provide support for the effectiveness of adding a cognitive dual-task module to the treatment of psychiatric outpatients with elevated depressive symptoms in reducing suicidal intrusions and ideation and can be executed safely.

Personally oriented model of education in the context of the concept of spiritual and practical development of the world in morality

The article outlines the importance of a personality-oriented model of education in the field of a harmonious combination of the interests of the individual, consisting of free self-development and preservation of individuality, and the interests of Russian society, the most important of which is the self-development of each of its members under the sign of morality. The theoretical foundations of a personality-oriented model of education are outlined: the value of the student’s personality; education of a person of culture as the goal of personality-oriented education; subjective experience of the individual as its content. It is proposed to consider a personality-oriented model of education as a theoretical construct formed by cognitive, axiological, activity-creative and personal modules, including knowledge, values, methods of activity and creativity, personal characteristics, respectively. The content of the activity-creative module is supplemented with such a component as a way of mastering the world in morality. The main provisions of the concept of spiritual and practical mastery of the world in morality are revealed: the mastery of the world by a person in morality presupposes knowledge of morality, which appears not in an explicit form, but in a transformed form – through a special method of assessment, through requirements; the individual not only assimilates moral demands proposed from the outside, but is an active subject in their development. The role of moral consciousness in a person’s spiritual and practical mastery of the world in morality is revealed, providing a search for the value-normative meaning of people’s actions and relationships, on the basis of which the relationships between people are assessed. It is substantiated that students’ spiritual and practical mastery of the world in morality is possible within the framework of a personality-oriented model of education.

Significant improvements were observed in the patient’s sleep quality, stress levels, and overall mental well-being over the course of treatment. This case report highlights the efficacy of the multi-modal approach in promoting mental health and resilience in high-stress occupations, emphasizing the value of holistic healing modalities in addressing complex mental health concerns.

Math Modules— A Theoretical Review and Cognitive Training Programme

The abstract outlines the content of a review on Math Modules, a program designed to facilitate the learning of foundational math skills through cognitive training techniques that are based on theory with a special focus on planning and executive functions, encompassing cognitive flexibility, attentional control, and working memory. The guiding educational principle is drawn from Vygotsky's concept of zones of proximal development, highlighting the belief that children can accomplish tasks with assistance that they may struggle with independently. In a way, the structure of cognitive training Modules can be viewed as an attempt at construct validity. A review of historical roots of Math modules is presented at some length. The program begins with the division of training the two key components of math proficiency: computing and solving word problems. Both rely on five essential skills.

Socially adaptive cognitive architecture for human-robot collaboration in industrial settings.

This paper introduces DAC-HRC, a novel cognitive architecture designed to optimize human-robot collaboration (HRC) in industrial settings, particularly within the context of Industry 4.0. The architecture is grounded in the Distributed Adaptive Control theory and the principles of joint intentionality and interdependence, which are key to effective HRC. Joint intentionality refers to the shared goals and mutual understanding between a human and a robot, while interdependence emphasizes the reliance on each other's capabilities to complete tasks. DAC-HRC is applied to a hybrid recycling plant for the disassembly and recycling of Waste Electrical and Electronic Equipment (WEEE) devices. The architecture incorporates several cognitive modules operating at different timescales and abstraction levels, fostering adaptive collaboration that is personalized to each human user. The effectiveness of DAC-HRC is demonstrated through several pilot studies, showcasing functionalities such as turn-taking interaction, personalized error-handling mechanisms, adaptive safety measures, and gesture-based communication. These features enhance human-robot collaboration in the recycling plant by promoting real-time robot adaptation to human needs and preferences. The DAC-HRC architecture aims to contribute to the development of a new HRC paradigm by paving the way for more seamless and efficient collaboration in Industry 4.0 by relying on socially adept cognitive architectures.

METHODOLOGY OF COGNITIVE-DISCURSIVE MODELLING OF LITERARY TRANSLATION (case study of Ukrainian retranslations of W. Shakespeare’s tragedies of the 19th–21st centuries)

The article provides theoretical and methodological substantiation for the step-by-step construction of a cognitive-discursive model of the diachronic plurality in translation of a time-remote original work, which appears as a tool for revealing the internal mechanisms of translating a literary work and determining the criteria for the adequacy of the original and translation. This is a case study of W. Shakespeare’s tragedies as time-remote original works of England of the late 16th – early 17th centuries and their Ukrainian retranslations of the 19th–21st centuries. The algorithm of the complex methodology of cognitive-discursive modelling of literary translation, which incorporates the methods of discourse analysis and cognitive translation studies, involves five stages of construction of three modules: discursive, cognitive, and retranslation. The construction of a discursive module, the aim of which is to reveal the objective and subjective factors that influence the process and result of the translator’s interpretation of a time-remote original work, involves the construction of three components – extralingual, lingual, and interpretation, which takes place in the first three stages. The fourth stage is the building of a cognitive module, which reveals the internal mechanisms of the translation process caused by cognitive consonance (harmonious identity of the mental processes of the author and the translator) or cognitive dissonance (epistemological, ideological, and cultural-aesthetic). Cognitive consonance and cognitive dissonance result from the similarities and differences in the contexts of original creation and retranslations, which are previously defined in the discursive module. The translator’s decision to choose one or another translation strategy and local tactic in conditions of cognitive consonance or cognitive dissonance determines different degrees of cognitive proximity of the original and the translation: cognitive equivalence, cognitive analogy, and cognitive variance. The fifth stage is the construction of a retranslation module, which affirms that the translator’s choice of strategy (modernization or archaization, domestication or foreignization) and tactic (reproductive or adaptive) of transformational translation is conditioned by cognitive consonance or dissonance. The relevance of the research is determined by its appeal to the leading cognitive-discursive paradigm of modern translation studies and by the tendency of cognitive translation studies for the translation process modelling, according to which not only the translation result is the subject of study, but also the prerequisites that determine the translator’s approach to the reproduction of the original text in one way or another. Analysis and comparison of retranslations of a time-remote original text in the course of modelling the process of literary translation allows following the influence of discursive and cognitive factors on the process and result of translation. The creation of the cognitive-discursive model of the diachronic plurality in translation of the time-remote original text explains the translation decisions regarding the choice of the general strategy and local tactic of retranslations and, respectively, the diachronic plurality in translations of a time-remote original text.
