Purpose: The primary purpose of this study was to identify the brain bases of phonological working memory (the short-term maintenance of speech sounds) using behavioral tasks analogous to clinically sensitive assessments of nonword repetition. The secondary purpose of the study was to identify how individual differences in brain activation were related to participants' nonword repetition abilities. Method: We used functional magnetic resonance imaging to measure neurophysiological response during a nonword discrimination task derived from standard clinical assessments of phonological working memory...

BACKGROUND/PURPOSE: Researchers have recently proposed a preclinical stage of dementia of Alzheimer's type (DAT), referred to as subjective memory impairment (SMI), with the aim of developing methods for the early detection of DAT and subsequent intervention. It has been proposed that the objective memory functions of individuals with SMI are normal; however, arbitrary and semantic associations are both used to describe the processes of memory. No previous studies have investigated these processes among individuals with SMI...

In everyday life we frequently rely on our abilities to postpone intentions until later occasions (prospective memory; PM) and to deactivate completed intentions even in stressful situations. Yet, little is known about the effects of acute stress on these abilities. In the present work we investigated the impact of acute stress on PM functioning under high task demands. 1) Different from previous studies, in which intention deactivation required mostly low processing demands, we used salient focal PM cues to induce high processing demands during intention-deactivation phases...

Correctly understood speech in difficult listening conditions is often more difficult to remember. A long-standing hypothesis for this observation is that the engagement of cognitive resources to aid speech understanding can limit resources available for memory encoding. This hypothesis is consistent with evidence that speech presented in difficult conditions typically elicits greater activity throughout cingulo-opercular regions of frontal cortex that are proposed to optimize task performance through adaptive control of behavior and tonic attention...

INTRODUCTION: Frailty is a strong predictor of adverse health events, but its impact on cognitive function is poorly understood. AIM: To assess cognitive performance in frailty and to identify the frailty stage where cognitive impairment begins. METHODS: Data were taken from 2044 people aged ≥65 years without cognitive impairment selected from the Toledo Study for Healthy Aging, a population-based cohort of older adults. Frailty status was assessed by 3 different scales: Frailty Phenotype (FP), Frailty Trait Scale (FTS), and Frailty Index (FI)...

AIM: Numerous neuropsychological tests are implemented in the clinical setting. However, a readily available cognitive test is required to detect the risk of dementia in the community setting. METHODS: A total of 4151 persons aged ≥65 years participated in the present prospective cohort study. We assessed cognitive performance using the Mini-Mental State Examination and the National Center for Geriatrics and Gerontology-Functional Assessment Tool. The National Center for Geriatrics and Gerontology-Functional Assessment Tool includes tests of story and word list memory, attention and executive function, processing speed, and visuospatial skill to screen for cognitive impairment...

Prior representations affect future learning. Little is known, however, about the effects of recollective or familiarity-based representations on such learning. We investigate the ability to reuse or reassociate elements from recollection- and familiarity-based associations to form new associations. Past neuropsychological research suggests that hippocampal, and presumably recollective, representations are more flexible than extra-hippocampal, presumably familiarity-based, representations. We therefore hypothesize that the elements of recollective associations, as opposed to familiarity-based representations, may be more easily manipulated and decoupled from each other, and facilitate the formation of new associations...

Despite a growing number of studies suggesting that emotion words affect perceptual judgments of emotional stimuli, little is known about how emotion words affect perceptual memory for emotional faces. In Experiments 1 and 2 we tested how emotion words (compared with control words) affected participants' abilities to select a target emotional face from among distractor faces. Participants were generally more likely to false alarm to distractor emotional faces when primed with an emotion word congruent with the face (compared with a control word)...

Suppression of aversive memories through memory control has historically been proposed as a central psychological defense mechanism. Inability to suppress memories is considered a central psychological trait in several psychiatric disorders, including Generalized Anxiety Disorder (GAD). Yet, few studies have attempted the focused identification of dysfunctional brain activation profiles when patients with Generalized Anxiety Disorders attempt memory control. Using a well-characterized behavioral paradigm we studied brain activation profiles in a group of adult GAD patients and well-matched healthy controls (HC)...

OBJECTIVE: Early and preferential targeting of limbic structures by Alzheimer disease (AD)-related pathology suggests emotion dysregulation may serve as a marker of AD risk. We studied emotional verbal memory in two groups at risk for AD, amnestic mild cognitive impairment (aMCI) and late-onset depression (LOD), to test the hypothesis that aMCI and LOD would be characterized by a negative bias in emotional memory, whereas cognitively normal (CN) adults would show the "positivity effect" associated with healthy aging...

BACKGROUND/AIMS: The aim of this study was to assess the ability of neuropsychological tests to differentiate autopsy-defined Alzheimer disease (AD) from subcortical ischemic vascular dementia (SIVD). METHODS: From a sample of 175 cases followed longitudinally that underwent autopsy, we selected 23 normal controls (NC), 20 SIVD, 69 AD, and 10 mixed cases of dementia. Baseline neuropsychological tests, including Memory Assessment Scale word list learning test, control oral word association test, and animal fluency, were compared between the three autopsy-defined groups...

Social transmission of memory and its consequence on collective memory have generated enduring interdisciplinary interest because of their widespread significance in interpersonal, sociocultural, and political arenas. We tested the influence of 3 key factors-emotional salience of information, group structure, and information distribution-on mnemonic transmission, social contagion, and collective memory. Participants individually studied emotionally salient (negative or positive) and nonemotional (neutral) picture-word pairs that were completely shared, partially shared, or unshared within participant triads, and then completed 3 consecutive recalls in 1 of 3 conditions: individual-individual-individual (control), collaborative-collaborative (identical group; insular structure)-individual, and collaborative-collaborative (reconfigured group; diverse structure)-individual...

Cognitive deficits are a potential part of the clinical picture of depression, especially when it comes to late-life depression. The present study was carried out to establish whether distinctive cognitive deficiencies can be linked with depression in the late-life period, especially in executive functioning, working memory, and visuospatial memory. Our sample consisted of 71 seniors in the age range between 69 and 85 years. A battery of neurocognitive tests was used, including tests of executive functioning (Trail Making Test [TMT], part B, Stroop color word test, semantic word fluency test, and partially Rey-Osterrieth Complex Figure test [ROCF]), tests of attention and working memory (TMT, part A and digit span), and test of visuospatil ability and memory (ROCF)...

BACKGROUND: Spaced retrieval training (SRT) is a nonpharmacological intervention for mild cognitive impairment (MCI) and dementia that trains the learning and retention of target information by recalling it over increasingly long intervals. We recently developed the Ubiquitous Spaced Retrieval-based Memory Advancement and Rehabilitation Training (USMART) program as a convenient, self-administered tablet-based SRT program. We also demonstrated the utility of USMART for improving memory in individuals with MCI through an open-label uncontrolled trial...

This pilot study attempted to study the applicability of neurofeedback for elderly persons living in nursing homes. We hypothesized an improve of cognitive functioning and the independence in daily life (IDL) of elderly people by using low beta (12-15HZ) EEG neurofeedback training (E-NFT). The participants (active E-NFT group, n=10; control group, n=6) were community living elderly women without dementia. Neurofeedback training was adjusted ten times within 9 weeks, with a training duration of 21 minutes by use of a single electrode, which was centrally placed on the skull surface...

Episodic memory is a complex memory system which allows recall and mental re-experience of previous episodes from one's own life. Real-life episodic memories are about events in their spatiotemporal context and are typically visuospatial, rather than verbal. Yet often, tests of episodic memory use verbal material to be recalled (word lists, stories). The Real-World What-Where-When memory test requires participants to hide a total of 16 different objects in 16 different locations over two temporal occasions, 2 h apart...
