Die Autoren haben nichts zu verraten.

In der hier vorgestellten Studie haben wir untersucht, ob ältere Erwachsene von der Ausbildung im Arbeitsgedächtnis profitieren könnten und ob sie mit dem Anfangsniveau ihrer Grundwahrnehmung verbunden sind. Wir verwendeten eine n-back-Aufgabe als experimentelle Intervention und Arbeitsgedächtniskapazität (gemessen mit der OSPAN-Aufgabe) war die Methode, um die anfängliche Intellektuelle Funktion der Teilnehmer zu untersuchen. Wir hatten zwei kritische Schritte im Protokoll. Die erste und wichtigste war die Bewertu...

In vielen kognitiven Trainingsstudien wird die duale n-back-Aufgabe als Methode des Arbeitsgedächtnisses (WM) verwendet. WM ist ein gemeinsames Ziel kognitiver Interventionen wegen seiner Bedeutung für andere, höhere intellektuelle Funktionen1. Jedoch, die Wirksamkeit dieser Ausbildung und ihr Potenzial für die Schaffung einer allgemeineren Verbesserung der Kognition, wurde sehr diskutiert (für Meta-Analyse, siehe2,3,4,5,6,7,14 und für Bewertungen, siehe4,8,9,10,11,12,13). Während einige Forscher behaupten, dass "...... es gab keine überzeugenden Beweise für die Verallgemeinerung der Arbeitsgedächtnisausbildung auf andere Fähigkeiten''4, andere präsentieren metaanalytische Daten, die sehr signifikante Auswirkungen der WM-Ausbildungzeigen 2,3,5,6,11. Das separate Problem ist die Wirksamkeit von WM in der älteren Bevölkerung. Mehrere WM-Trainingsstudien berichteten über größere Vorteile bei jüngeren Erwachsenen im Vergleich zu älteren Erwachsenen15,16,17,18,19,20, während andere zeigen, dass ähnliche Effekte in beiden Altersgruppen beobachtet werden können21,22,23,24,25.
Verschiedene Elemente werden geglaubt, um die Vorteile des Gedächtnistrainings zu prognostizieren26. Einige dieser Faktoren scheinen potenzielle Moderatoren der WM-Trainingseffektivität21zu sein. Mentale Kapazität, beschrieben als die Grundlegende kognitive Kapazität oder allgemeine kognitive Ressource, scheint eine der stärksten Entscheidungen für diese Position zu sein. Um die Rolle der anfänglichen intellektuellen Ebene zu bewerten, legen wir einen besonderen Schwerpunkt (die hier beschriebene Methode) auf die Messung der kognitiven Fähigkeiten, bevor wir ein Trainingsschema anwenden. Es wurde durch die Daten diktiert, die zeigen, dass die Teilnehmer, die durch höhere kognitive Fähigkeiten zu Beginn des Trainings gekennzeichnet sind, erreichten wesentlich bessere Trainingsergebnisse im Vergleich zu denen mit einem niedrigeren Niveau der anfänglichen kognitiven Funktion27. Ein ähnliches Phänomen wird in der Bildungsforschung beobachtet, wo es als Matthäus-Effekt28bezeichnet wird, eine Beobachtung, dass Menschen mit anfänglich besseren Fähigkeiten noch mehr verbessern, wenn sie im Vergleich zu denen mit vorläufig niedrigeren Fähigkeiten in Frage.
Es ist jedoch nachdenklich, dass nicht so viele Berichte zu diesem Thema veröffentlicht wurden21,29. Darüber hinaus bleiben selbst erhebliche individuelle Unterschiede, insbesondere bei älteren Menschen, bei der Datenanalyse und -interpretation oft unbeaufsichtigt30. In der vorliegenden Studie untersuchen wir die Auswirkungen der anfänglichen Arbeitsgedächtniskapazität auf den Erfolg des WM-Trainings in der Gruppe der gesunden älteren Erwachsenen. Um jedes Element der Ausbildungsschemas zwischen Versuchs- und Kontrollgruppen so ähnlich wie möglich zu halten, haben wir ein aktives Kontrollgruppendesign eingesetzt. Daher blieben die Trainingsinhalte (WM versus semantisches Gedächtnis) der entscheidende Faktor, der den erwarteten Unterschied in den Trainingsergebnissen bestimmt. Beide Gruppen führten computergestützte, heimbasierte Schulungen durch. Die Mitglieder der experimentellen Gruppe wurden einem adaptiven dualen n-Back-Trainingsprogramm und einer aktiven Steuerungsgruppe zugewiesen, die mit einer Aufgabe trainiert wurde, die auf einem semantischen Speicherquiz basiert. Neu im Ansatz ist hier die Betonung der ersten Bewertung des kognitiven Niveaus der Teilnehmer durch die Bewertung ihrer Arbeitsgedächtniskapazität (WMC). Darüber hinaus hat sich die Methode zur Bewertung des anfänglichen WMC-Levels, das wir in diesem Artikel präsentieren, als ein wirksames Werkzeug bei der Unterscheidung zwischen Personen erwiesen, die während des nachfolgenden Arbeitsgedächtnistrainings erfolgreich sein werden und nicht. Wir haben zuvor die Ergebnisse dieser Studie beschrieben und veröffentlicht44. Daher konzentrieren wir uns in diesem Artikel auf eine detaillierte Beschreibung des Protokolls, das wir verwendet haben.

working memory training for older participants: a control group training regimen and initial intellectual functioning assessment

Die Wirksamkeit kognitiver Trainingsinterventionen wird in letzter Zeit heftig diskutiert. Es gibt keinen Konsens darüber, welche Art von Ausbildungsregime am effektivsten ist. Auch einzelne Merkmale als Prädiktoren des Trainingsergebnisses werden noch untersucht. In diesem Artikel zeigen wir den Versuch, dieses Problem anzugehen, indem wir nicht nur die Auswirkungen des Arbeitsgedächtnistrainings (WM) auf die kognitive Wirksamkeit älterer Erwachsener untersuchen, sondern auch den Einfluss der anfänglichen WM-Kapazität (WMC) auf das Trainingsergebnis. Wir beschreiben detailliert, wie man 5 Wochen eines adaptiven Dual-N-Back-Trainings mit einer aktiven Steuerungsgruppe (Speicherquiz) durchführt. Wir konzentrieren uns hier auf technische Aspekte der Ausbildung sowie auf die erste Bewertung des WMC der Teilnehmer. Die Bewertung der Pre- und Post-Training-Leistung anderer kognitiver Dimensionen basierte auf den Ergebnissen von Tests der Gedächtnisaktualisierung, Hemmung, Aufmerksamkeitsverschiebung, Kurzzeitgedächtnis (STM) und Argumentation. Wir haben festgestellt, dass das anfängliche Niveau von WMC die Effizienz der n-Back-Trainingsintervention vorhersagt. Wir haben auch die Verbesserung nach dem Training in fast allen Aspekten der kognitiven Funktion, die wir gemessen haben, bemerkt, aber diese Effekte waren meist interventionunabhängig.

Trainingsbezogene Effekte

Training Synesthetic Letter-color Associations by Reading in Color

Synesthesia is a rare condition in which a stimulus from one modality automatically and consistently triggers unusual sensations in the same and/or other modalities. A relatively common and well-studied type is grapheme-color synesthesia, defined as the consistent experience of color when viewing, hearing and thinking about letters, words and numbers. We describe our method for investigating to what extent synesthetic associations between letters and colors can be learned by reading in color in nonsynesthetes. Reading in color is a special method for training associations in the sense that the associations are learned implicitly while the reader reads text as he or she normally would and it does not require explicit computer-directed training methods. In this protocol, participants are given specially prepared books to read in which four high-frequency letters are paired with four high-frequency colors. Participants receive unique sets of letter-color pairs based on their pre-existing preferences for colored letters. A modified Stroop task is administered before and after reading in order to test for learned letter-color associations and changes in brain activation. In addition to objective testing, a reading experience questionnaire is administered that is designed to probe for differences in subjective experience. A subset of questions may predict how well an individual learned the associations from reading in color. Importantly, we are not claiming that this method will cause each individual to develop grapheme-color synesthesia, only that it is possible for certain individuals to form letter-color associations by reading in color and these associations are similar in some aspects to those seen in developmental grapheme-color synesthetes. The method is quite flexible and can be used to investigate different aspects and outcomes of training synesthetic associations, including learning-induced changes in brain function and structure.

Reading in color is a new method for training letter-color associations that are typically found only in grapheme-color synesthetes. It involves an implicit form of training that has potential for long-term associative training methods&#160;because the training is a byproduct of reading and any text can be colored.

A Cognitive Paradigm to Investigate Interference in Working Memory by Distractions and Interruptions

Goal-directed behavior is often impaired by interference from the external environment, either in the form of distraction by irrelevant information that one attempts to ignore, or by interrupting information that demands attention as part of another (secondary) task goal. Both forms of external interference have been shown to detrimentally impact the ability to maintain information in working memory (WM). Emerging evidence suggests that these different types of external interference exert different effects on behavior and may be mediated by distinct neural mechanisms. Better characterizing the distinct neuro-behavioral impact of irrelevant distractions versus attended interruptions is essential for advancing an understanding of top-down attention, resolution of external interference, and how these abilities become degraded in healthy aging and in neuropsychiatric conditions. This manuscript describes a novel cognitive paradigm developed the Gazzaley lab that has now been modified into several distinct versions used to elucidate behavioral and neural correlates of interference, by to-be-ignored distractors versus to-be-attended interruptors. Details are provided on variants of this paradigm for investigating interference in visual and auditory modalities, at multiple levels of stimulus complexity, and with experimental timing optimized for electroencephalography (EEG) or functional magnetic resonance imaging (fMRI) studies. In addition, data from younger and older adult participants obtained using this paradigm is reviewed and discussed in the context of its relationship with the broader literatures on external interference and age-related neuro-behavioral changes in resolving interference in working memory.

Vision Training Methods for Sports Concussion Mitigation and Management

There is emerging evidence supporting the use vision training, including light board training tools, as a concussion baseline and neuro-diagnostic tool and potentially as a supportive component to concussion prevention strategies. This paper is focused on providing detailed methods for select vision training tools and reporting normative data for comparison when vision training is a part of a sports management program. The overall program includes standard vision training methods including tachistoscope, Brock&#8217;s string, and strobe glasses, as well as specialized light board training algorithms. Stereopsis is measured as a means to monitor vision training affects. In addition, quantitative results for vision training methods as well as baseline and post-testing *A and Reaction Test measures with progressive scores are reported. Collegiate athletes consistently improve after six weeks of training in their stereopsis, *A and Reaction Test scores. When vision training is initiated as a team wide exercise, the incidence of concussion decreases in players who participate in training compared to players who do not receive the vision training. Vision training produces functional and performance changes that, when monitored, can be used to assess the success of the vision training and can be initiated as part of a sports medical intervention for concussion prevention.

This paper describes a protocol to conduct, quantitatively monitor, and assess the success of vision training initiated as part of a sports medical management program including intervention for concussion prevention and performance enhancement.

Combined Shuttle-Box Training with Electrophysiological Cortex Recording and Stimulation as a Tool to Study Perception and Learning

Shuttle-box avoidance learning is a well-established method in behavioral neuroscience and experimental setups were traditionally custom-made; the necessary equipment is now available by several commercial companies. This protocol provides a detailed description of a two-way shuttle-box avoidance learning paradigm in rodents (here Mongolian gerbils; Meriones unguiculatus) in combination with site-specific electrical intracortical microstimulation (ICMS) and simultaneous chronical electrophysiological in vivo recordings. The detailed protocol is applicable to study multiple aspects of learning behavior and perception in different rodent species.
Site-specific ICMS of auditory cortical circuits as conditioned stimuli here is used as a tool to test the perceptual relevance of specific afferent, efferent and intracortical connections. Distinct activation patterns can be evoked by using different stimulation electrode arrays for local, layer-dependent ICMS or distant ICMS sites. Utilizing behavioral signal detection analysis it can be determined which stimulation strategy is most effective for eliciting a behaviorally detectable and salient signal. Further, parallel multichannel-recordings using different electrode designs (surface electrodes, depth electrodes, etc.) allow for investigating neuronal observables over the time course of such learning processes. It will be discussed how changes of the behavioral design can increase the cognitive complexity (e.g. detection, discrimination, reversal learning).

Shuttle-box avoidance learning is well-established in behavioral neuroscience. This protocol describes how shuttle-box learning in rodents can be combined with site-specific electrical intracortical microstimulation (ICMS) and simultaneous chronical in vivo recordings as a tool to study multiple aspects of learning and perception.

Pavlovian Conditioned Approach Training in Rats

Cues that are contingently paired with unconditioned, rewarding stimuli can acquire rewarding properties themselves through a process known as the attribution of incentive salience, or the transformation of neutral stimuli into attractive, &#34;wanted&#39; stimuli capable of motivating behavior. Pavlovian conditioned approach (PCA) develops after the response-independent presentation of a conditioned stimulus (CS; e.g., a lever) that predicts the delivery of an unconditioned stimulus (US; e.g., a food pellet) and can be used to measure incentive salience. During training, three patterns of conditioned responses (CRs) can develop: sign-tracking behavior (CS-directed CR), goal-tracking behavior (US-directed CR), and an intermediate response (both CRs). Sign-trackers attribute incentive salience to reward-related cues and are more vulnerable to cue-induced reinstatement of drug-seeking as well as other addiction-related behaviors, making PCA a potentially valuable procedure for studying addiction vulnerability. Here, we describe materials and methods used to elicit PCA behavior from rats as well as analyze and interpret PCA behavior in individual experiments.

Here, we present a protocol to elicit Pavlovian conditioned approach behavior in rats. This procedure can be used to measure individual differences in the tendency to approach and attribute incentive salience to reward-related cues and investigate addiction vulnerability.

Assessing Working Memory in Children: The Comprehensive Assessment Battery for Children &#8211; Working Memory (CABC-WM)

The Comprehensive Assessment Battery for Children - Working Memory (CABC-WM) is a computer-based battery designed to assess different components of working memory in young school-age children. Working memory deficits have been identified in children with language-based learning disabilities, including dyslexia1,2 and language impairment3,4, but it is not clear whether these children exhibit deficits in subcomponents of working memory, such as visuospatial or phonological working memory. The CABC-WM is administered on a desktop computer with a touchscreen interface and was specifically developed to be engaging and motivating for children. Although the long-term goal of the CABC-WM is to provide individualized working memory profiles in children, the present study focuses on the initial success and utility of the CABC-WM for measuring central executive, visuospatial, phonological loop, and binding constructs in children with typical development. Immediate next steps are to administer the CABC-WM to children with specific language impairment, dyslexia, and comorbid specific language impairment and dyslexia.

Introducing Clicker Training as a Cognitive Enrichment for Laboratory Mice

Establishing new refinement strategies in laboratory animal science is a central goal in fulfilling the requirements of Directive 2010/63/EU. Previous research determined a profound impact of gentle handling protocols on the well-being of laboratory mice. By introducing clicker training to the keeping of mice, not only do we promote the amicable treatment of mice, but we also enable them to experience cognitive enrichment. Clicker training is a form of positive reinforcement training using a conditioned secondary reinforcer, the "click" sound of a clicker, which serves as a time bridge between the strengthened behavior and an upcoming reward. The effective implementation of the clicker training protocol with a cohort of 12 BALB/c inbred mice of each sex proved to be uncomplicated. The mice learned rather quickly when challenged with tasks of the clicker training protocol, and almost all trained mice overcame the challenges they were given (100% of female mice and 83% of male mice). This study has identified that clicker training for mice strongly correlates with reduced fear in the mice during human-mice interactions, as shown by reduced anxiety-related behaviors (e.g., defecation, vocalization, and urination) and fewer depression-like behaviors (e.g., floating). By developing a reliable protocol that can be easily integrated into the daily routine of the keeping of laboratory mice, the lifetime experience of welfare in the mice can be improved substantially.

The development of new refinement strategies for laboratory mice is a challenging task that contributes towards fulfilling the 3R principle. This protocol introduces clicker training as a cognitive enrichment program for laboratory mice.

Reducing State Anxiety Using Working Memory Maintenance

The purpose of this protocol is to explain how to examine the relationship between working memory processes and anxiety by combining the Sternberg Working Memory (WM) and the threat of shock paradigms. In the Sternberg WM paradigm, subjects are required to maintain a series of letters in the WM for a brief interval and respond by identifying whether the position of a given letter in the series matches a numerical prompt. In the threat of shock paradigm, subjects are exposed to alternating blocks where they are either at risk of receiving unpredictable presentations of a mild electric shock or are safe from the shock. Anxiety is probed throughout the safe and threat blocks using the acoustic startle reflex, which is potentiated under threat (Anxiety-Potentiated Startle (APS)). By conducting the Sternberg WM paradigm during the threat of shock and probing the startle response during either the WM maintenance interval or the intertrial interval, it is possible to determine the effect of WM maintenance on APS.

This protocol demonstrates how to measure anxiety-potentiated startle during the Sternberg Working Memory paradigm.

Paradigms of Lower Extremity Electrical Stimulation Training After Spinal Cord Injury

Skeletal muscle atrophy, increased adiposity and reduced physical activity are key changes observed after spinal cord injury (SCI) and are associated with numerous cardiometabolic health consequences. These changes are likely to increase the risk of developing chronic secondary conditions and impact the quality of life in persons with SCI. Surface neuromuscular electrical stimulation evoked resistance training (NMES-RT) was developed as a strategy to attenuate the process of skeletal muscle atrophy, decrease ectopic adiposity, improve insulin sensitivity and enhance mitochondrial capacity. However, NMES-RT is limited to only a single muscle group. Involving multiple muscle groups of the lower extremities may maximize the health benefits of training. Functional electrical stimulation-lower extremity cycling (FES-LEC) allows for the activation of 6 muscle groups, which is likely to evoke greater metabolic and cardiovascular adaptation. Appropriate knowledge of the stimulation parameters is key to maximizing the outcomes of electrical stimulation training in persons with SCI. Adopting strategies for long-term use of NMES-RT and FES-LEC during rehabilitation may maintain the integrity of the musculoskeletal system, a pre-requisite for clinical trials aiming to restore walking after injury. The current manuscript presents a combined protocol using NMES-RT prior to FES-LEC. We hypothesize that muscles conditioned for 12 weeks prior to cycling will be capable of generating greater power, cycle against higher resistance and result in greater adaptation in persons with SCI.

Spinal cord injury is a traumatic medical condition that may result in elevated risks of chronic secondary metabolic disorders. Here, we presented a protocol using surface neuromuscular electrical stimulation-resistance training in conjunction with functional electrical stimulation-lower extremities cycling as a strategy to ameliorate several of these medical problems.

A Vibrotactile Feedback Device for Seated Balance Assessment and Training

Postural perturbations, motion tracking, and sensory feedback are modern techniques used to challenge, assess, and train upright sitting, respectively. The goal of the developed protocol is to construct and operate a sitting platform that can be passively destabilized while an inertial measurement unit quantifies its motion and vibrating elements deliver tactile feedback to the user. Interchangeable seat attachments alter the stability level of the device to safely challenge sitting balance. A built-in microcontroller allows fine-tuning of the feedback parameters to augment sensory function. Posturographic measures, typical of balance assessment protocols, summarize the motion signals acquired during timed balance trials. No dynamic sitting protocol to date provides variable challenge, quantification, and sensory feedback free of laboratory constraints. Our results demonstrate that non-disabled users of the device exhibit significant changes in posturographic measures when balance difficulty is altered or vibrational feedback provided. The portable, versatile device has potential applications in rehabilitation (following skeletal, muscular, or neurological injury), training (for sports or spatial awareness), entertainment (via virtual or augmented reality), and research (of sitting-related disorders).

A sitting platform has been developed and assembled that passively destabilizes sitting posture in humans. During the user&#39;s stabilizing task, an inertial measurement unit records the device&#39;s motion, and vibrating elements deliver performance-based feedback to the seat. The portable, versatile device may be used in rehabilitation, assessment, and training paradigms.
