Gli autori non hanno nulla da rivelare.

Nello studio qui presentato, abbiamo esaminato se gli anziani potessero beneficiare della formazione sulla memoria di lavoro e se fosse collegato al livello iniziale della loro cognizione di base. Abbiamo utilizzato un compito n-back come intervento sperimentale e la capacità di memoria di lavoro (misurata con l'attività OSPAN) era il metodo per sondare il livello iniziale di funzionamento intellettuale dei partecipanti. Abbiamo avuto due passaggi critici nel protocollo. Il primo e più importante è stata la valutazio...

In molti studi di formazione cognitiva, il doppio compito n-back viene utilizzato come metodo di formazione sulla memoria di lavoro (WM). WM è un obiettivo comune degli interventi cognitivi a causa della sua importanza per altre funzioni intellettuali di livello superiore1. Tuttavia, l'efficacia di tale formazione e il suo potenziale per creare un miglioramento più generale della cognizione, è stato molto dibattuto (per la meta-analisi,vedi 2,3,4,5,6,7,14 e per le recensioni, vedi4,8,9,10,11,12,13). Mentre alcuni ricercatori sostengono che ''... non vi erano prove convincenti della generalizzazione della formazione sulla memoria di lavoro ad altrecompetenze'' 4, altrepresentano dati meta-analitici, che mostrano effetti altamente significativi della formazione WM2,3,5,6,11. Il problema separato è l'efficacia delle armi di distruzione di qualità nella popolazione anziana. Diversi studi di formazione wm hanno riportato maggiori benefici negli adulti più giovani rispetto agli adulti più anziani15,16,17,18,19,20, mentre altri mostrano che effetti simili possono essere osservati in entrambe le fasce dietà 21,22,23,24,25.
Si ritiene che vari elementi presci suscittero i vantaggi dell'allenamentodella memoria 26. Alcuni di questi fattori sembrano essere potenziali moderatori dell'efficacia della formazione WM21. La capacità mentale, essendo descritta come la capacità cognitiva di base o la risorsa cognitiva generale, sembra essere una delle scelte più forti per questa posizione. Al fine di valutare il ruolo del livello intellettuale iniziale, abbiamo posto un'enfasi speciale (il metodo qui descritto) sulla misurazione della capacità cognitiva prima di applicare un regime di allenamento. È stato dettato dai dati che mostrano che i partecipanti, che sono caratterizzati da una maggiore capacità cognitiva all'inizio della formazione, hanno raggiunto risultati di allenamento sostanzialmente migliori rispetto a quelli con livelli inferiori di funzione cognitivainiziale 27. Un fenomeno simile si osserva nella ricerca educativa, dove viene indicato come l'effetto Matthew28, un'osservazione che le persone con abilità inizialmente migliori migliorano ancora di più rispetto a quelle con un livello preliminare inferiore di capacità in questione.
Tuttavia, è stimolante che non siano state pubblicate così tante relazioni su questo argomento21,29. Inoltre, anche differenze individuali sostanziali, soprattutto quando si tratta della popolazione anziana, sono spesso lasciate incustodite durante l'analisi e l'interpretazionedei dati 30. Nel presente studio, esaminiamo l'impatto del livello iniziale di capacità di memoria di lavoro sul successo della formazione WM nel gruppo di anziani sani. Al fine di mantenere ogni elemento dei regimi di formazione il più simile possibile tra gruppi sperimentali e di controllo, abbiamo utilizzato un progetto di gruppo di controllo attivo. Pertanto, il contenuto del training (WM rispetto alla memoria semantica) è rimasto l'unico fattore cruciale che determina la differenza prevista nei risultati del training. Entrambi i gruppi eseguivano corsi di formazione computerizzati basati sulla casa. I membri del gruppo sperimentale sono stati assegnati a un programma di formazione dual n-back adattivo e a un gruppo di controllo attivo addestrato con un'attività basata su un quiz sulla memoria semantica. Una novità nell'approccio qui è l'enfasi sulla valutazione iniziale del livello cognitivo dei partecipanti valutando la loro capacità di memoria di lavoro (WMC). Inoltre, il metodo di valutazione del livello WMC iniziale che presentiamo in questo articolo si è dimostrato uno strumento efficace per distinguere tra persone che avranno o non avranno successo durante il successivo training della memoria di lavoro. Abbiamo precedentemente descritto e pubblicato i risultati di questo studio44. Pertanto, in questo articolo ci stiamo concentrando su una descrizione dettagliata del protocollo che abbiamo usato.

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

L'efficacia degli interventi di formazione cognitiva è recentemente molto dibattuta. Non c'è consenso sul tipo di regime di formazione più efficace. Inoltre, le caratteristiche individuali come predittori dei risultati della formazione sono ancora in fase di studio. In questo articolo viene mostrato il tentativo di risolvere questo problema esaminando non solo l'impatto della formazione sulla memoria di lavoro (WM) sull'efficacia cognitiva negli adulti più anziani, ma anche l'influenza della capacità WMC iniziale sul risultato della formazione. Descriviamo in dettaglio come eseguire 5 settimane di un allenamento dual n-back adattivo con un gruppo di controllo attivo (quiz sulla memoria). Ci stiamo concentrando sugli aspetti tecnici della formazione e sulla valutazione iniziale del WMC dei partecipanti. La valutazione delle prestazioni pre e post allenamento di altre dimensioni cognitive si è basata sui risultati dei test di aggiornamento della memoria, inibizione, spostamento dell'attenzione, memoria a breve termine (STM) e ragionamento. Abbiamo scoperto che il livello iniziale di WMC prevede l'efficienza dell'intervento di formazione n-back. Abbiamo anche notato il miglioramento post-allenamento in quasi tutti gli aspetti del funzionamento cognitivo che abbiamo misurato, ma questi effetti erano per lo più indipendenti dall'intervento.

Effetti relativi alla formazione
85 soggetti hanno partecipato allo studio (29 erano maschi) e avevano in media 66,7 anni. A causa di problemi tecnici, i dati di un partecipante al gruppo di formazione n-back non sono stati registrati. Infine, sono stati analizzati i dati di 43 partecipanti al gruppo di formazione n-back e 42 nel gruppo di formazione Quiz. L'analisi multivariata della varianza (MANOVA) con misur...

The main goal of this study was to assess the usability of a tablet-computer-based application (EmoCogMeter) in investigating the effects of age on cognitive functions across the lifespan in a sample of 378 healthy subjects (age range 18-89 years). Consistent with previous findings we found an age-related cognitive decline across a wide range of neuropsychological domains (memory, attention, executive functions), thereby proving the usability of our tablet-based application. Regardless of prior computer experience, subjects of all age groups were able to perform the tasks without instruction or feedback from an experimenter. Increased motivation and compliance proved to be beneficial for task performance, thereby potentially increasing the validity of the results. Our promising findings underline the great clinical and practical potential of a tablet-based application for detection and monitoring of cognitive dysfunction.

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.

A novel cognitive paradigm is developed to elucidate behavioral and neural correlates of interference by to-be-ignored distractors versus interference by to-be-attended interruptors during a working memory task. In this manuscript, several variants of this paradigm are detailed, and data obtained with this paradigm in younger/older adult participants is reviewed.

The 4 Mountains Test: A Short Test of Spatial Memory with High Sensitivity for the Diagnosis of Pre-dementia Alzheimer's Disease

This protocol describes the administration of the 4 Mountains Test (4MT), a short test of spatial memory, in which memory for the topographical layout of four mountains within a computer-generated landscape is tested using a delayed match-to-sample paradigm. Allocentric spatial memory is assessed by altering the viewpoint, colors and textures between the initially presented and target images.
Allocentric spatial memory is a key function of the hippocampus, one of the earliest brain regions to be affected in Alzheimer&#39;s disease (AD) and impairment of hippocampal function predates the onset of dementia. It was hypothesized that performance on the 4MT would aid the diagnosis of predementia AD, which manifests clinically as Mild Cognitive Impairment (MCI).
The 4MT was applied to patients with MCI, stratified further based on cerebrospinal fluid (CSF) AD biomarker status (10 MCI biomarker positive, 9 MCI biomarker negative), and with mild AD dementia, as well as healthy controls. Comparator tests included tests of episodic memory and attention widely accepted as sensitive measures of early AD. Behavioral data were correlated with quantitative MRI measures of the hippocampus, precuneus and posterior cingulate gyrus.
4MT scores were significantly different between the two MCI groups (p = 0.001), with a test score of &#8804;8/15 associated with 100% sensitivity and 78% specificity for the classification of MCI with positive AD biomarkers, i.e., predementia AD. 4MT test scores correlated with hippocampal volume (r = 0.42) and cortical thickness of the precuneus (r = 0.55).
In conclusion, the 4MT is effective in identifying the early stages of AD. The short duration, easy application and scoring, and favorable psychometric properties of the 4MT fulfil the need for a simple but accurate diagnostic test for predementia AD.

This article describes the 4 Mountains Test (4MT), a hippocampus-dependent test of working allocentric spatial memory. The hippocampus is affected early in Alzheimer's disease (AD) and this article outlines the 4MT methodology and results of patient testing, which demonstrates the value of the 4MT in the diagnosis of pre-dementia AD.

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.

Working memory predicts a significant amount of variance for a variety of cognitive tasks, including speaking, reading, and writing. However, few tools are available to assess working memory in children. We present an innovative, computer-based battery that comprehensively assesses different components of working memory in school-age children.

Highlighting and Reducing the Impact of Negative Aging Stereotypes During Older Adults' Cognitive Testing

As life expectancy increases, aging has become a major health challenge, resulting in a huge effort to better discriminate between normal and pathological cognitive decline. It is thus essential that cognitive tests and their administration are as fair as possible. However, an important source of bias during cognitive testing comes from negative aging stereotypes that can impair the memory performance of older adults and inflate age differences on cognitive tasks. The fear of confirming negative aging stereotypes creates an extra pressure among older adults which interferes with their intellectual functioning and leads them to perform below their true abilities. Here, we present a protocol that highlights simple but efficient interventions to alleviate this age-based stereotype threat effect. The first study showed that simply informing older participants about the presence of younger participants (threat condition) led older adults to underperform on a standardized memory test compared with younger participants, and that this performance difference was eliminated when the test was presented as age-fair (reduced-threat condition). The second study replicated these findings on short cognitive tests used to screen for predementia in clinical settings and showed that teaching older adults about stereotype threat inoculated them against its effects. These results provide useful recommendations about how to improve older adults' memory assessment both in Iab studies and in clinical settings.

Here, we present a protocol designed to show how negative aging stereotypes can impair memory performance of older adults during cognitive testing and how to reduce this deleterious effect. This method can help older people to perform at an optimal level during testing in both lab studies and clinical settings.

Multimodal Protocol for Assessing Metacognition and Self-Regulation in Adults with Learning Difficulties

Learning disabilities (LDs) encompass disorders of those who have difficulty learning and using academic skills, exhibiting performance below expectations for their chronological age in the areas of reading, writing, and/or mathematics. Each of the disorders making up the LDs involve different deficits; however, some commonalities can be found within that heterogeneity, such in terms of learning self-regulation and metacognition. Unlike in early ages and later educational levels, there are hardly any evidence-based evaluation protocols for adults with LDs. LDs influence academic performance but also have serious consequences in professional, social, and family contexts. In response to this, the current work proposes a multimodal evaluation protocol focused on metacognitive, self-regulation of learning, and emotional processes, which make up the basis of the difficulties in adults with LDs. The assessment is carried out through analysis of the on-line learning process using a variety methods, techniques, and sensors (e.g., eye tracking, facial expressions of emotion, physiological responses, concurrent verbalizations, log files, screen recordings of human-machine interactions) and off-line methods (e.g., questionnaires, interviews, and self-report measures). This theoretically-driven and empirically-based guideline aims to provide an accurate assessment of LDs in adulthood in order to design effective prevention and intervention proposals.

A Computerized Functional Skills Assessment and Training Program Targeting Technology Based Everyday Functional Skills

Today, many functional skills are technology-based, so development of a technology-based training program has broad importance. Here we present a computerized functional skills training program that was paired in half of the participants with a commercially available cognitive training (CCT) program.
Non-impaired older individuals (NC) aged 60+ (n=45) and similarly aged individuals with mild cognitive impairment (MCI; n=50) were randomized to receive 12 weeks of twice-weekly computerized functional skills training (CFST) or 12 weeks of twice-weekly sessions split between CCT and CFST. Skills trained were use of an ATM; internet banking; ticket kiosk; telephone and internet prescription refill; medication management; and internet shopping. As with previous functional capacity assessments, we focus on completion time for each simulation.
51 participants completed the training program, either by mastering all 6 tasks (34) or completing 12 weeks of training. 44 more participants completed 4 or more training sessions so they were also analyzed for improvement up to their last training session. Completion time for all 6 tests significantly improved from the baseline assessment to the final training session in both groups of participants (all p&#60;0.001 with an average improvement in task completion time of 45%). Further, there was no differential improvement in MCI and NC in the 6 tests from baseline to end of training (all t&#60;1.66, all p&#62;0.12). Finally, combined CCT plus CFST did not differ from CSFT alone on any of the percent-change score measures (all t&#60;1.64, all p&#62;0.11).
Both NC and MCI groups evidenced substantial improvements in performance. CCT supplementation led to similar functional gains with half as many training sessions. The NC participants proceeded through the training fairly rapidly even without CCT supplementation; MCI participants required more training but learned equivalently. These findings suggest that even in cases with memory impairments, functional skills can be efficiently learned with training.

This training protocol uses computerized training to teach technology-related everyday functional skills. These skills include financial skills, travel and transit, as well as medication management.

A Metric Test for Assessing Spatial Working Memory in Adult Rats Following Traumatic Brain Injury

Impairments to sensory, short-term, and long-term memory are common side effects after traumatic brain injury (TBI). Due to the ethical limitations of human studies, animal models provide suitable alternatives to test treatment methods, and to study the mechanisms and related complications of the condition. Experimental rodent models have historically been the most widely used due to their accessibility, low cost, reproducibility, and validated approaches. A metric test, which tests the ability to recall the placement of two objects at various distances and angles from one another, is a technique to study impairment in spatial working memory (SWM) after TBI. The significant advantages of metric tasks include the possibility of dynamic observation, low cost, reproducibility, relative ease of implementation, and low stress environment. Here, we present a metric test protocol to measure impairment of SWM in adult rats after TBI. This test provides a feasible way to evaluate physiology and pathophysiology of brain function more effectively.

Traumatic brain injury (TBI) is commonly associated with memory impairment. Here, we present a protocol to assess spatial working memory after TBI via a metric task. A metric test is a useful tool to study spatial working memory impairment after TBI.

Metacognitive Development: How Children Estimate Their Memory

Source: Laboratories of Judith Danovitch and Nicholaus Noles&#8212;University of Louisville
Human memory is fallible, and people often cannot accurately recall what they have seen or heard. Adults are aware of their limited memory capacity, so they use strategies, such as rehearsal and mnemonic devices, to improve their recall of important information. Because adults understand the limits of memory, they know it makes more sense to write down the items on their shopping list rather than to try to remember the items when they get to the store. This ability to think about one&#8217;s own memory is called metamemory. Metamemory is one component of a broader set of cognitive processes that allow humans to think about their own knowledge and thinking, which is called metacognition.
Although young children understand that people have thoughts and a limited amount of knowledge, they often have trouble acknowledging the limits of their own knowledge and cognitive skills. Children&#8217;s ability to accurately estimate their own memory capacity and abilities improves over the elementary school years. One common way of measuring metamemory and its development is by giving children an opportunity to predict how well they can remember something, and then observing how well their prediction matches their actual recall.
This experiment demonstrates how to measure children&#8217;s metamemory based on the methods developed by Shin, Bjorklund, and Beck.1

Measuring Verbal Working Memory Span

Source: Laboratory of Jonathan Flombaum&#8212;Johns Hopkins University

Why is it relatively hard to remember everything on a shopping list if it includes more than just a handful of items? Why is it possible to remember a phone number that one just heard, but not two or three phone numbers at once? Why is it difficult to remember names when several new people are introduced at the same time?
The answer has to do with the fact that over short-durations people rely on a specialized memory system called working memory. Unlike long-term memory, working memory has a very limited capacity. It is there so that information can be kept in mind, studied, manipulated, and then transferred to other memory and cognitive systems. But in order to serve in this active role, it needs to be selective, admitting only limited amounts of information at a time.
Experimental psychologists tend to think that people possess independent working memory systems for different kinds of information, with a major division between verbal and visual information. Each of these systems has an independent capacity limit.
To measure a person&#8217;s verbal working memory capacity limit&#8212;often called, his or her memory span&#8212;experimental psychologists often use a verbal list paradigm.
This video will demonstrate the measurement of verbal working memory span using a verbal list paradigm.
