Abstract
INTRODUCTION The Rey Auditory Verbal Learning Test (RAVLT) is a useful neuropsychological test for describing episodic memory impairment in dementia. However, there is limited research on its utility in early-onset Alzheimer's disease (EOAD). We assess the influence of amyloid and diagnostic syndrome on several memory scores in EOAD. METHODS We transcribed RAVLT recordings from 303 subjects in the Longitudinal Early-Onset Alzheimer's Disease Study. Subjects were grouped by amyloid status and syndrome. Primacy, recency, J-curve, duration, stopping time, and speed score were calculated and entered into linear mixed effects models as dependent variables. RESULTS Compared with amyloid negative subjects, positive subjects exhibited effects on raw score, primacy, recency, and stopping time. Inter-syndromic differences were noted with raw score, primacy, recency, J-curve, and stopping time. DISCUSSION RAVLT measures are sensitive to the effects of amyloid and syndrome in EOAD. Future work is needed to quantify the predictive value of these scores. HIGHLIGHTS RAVLT patterns characterize various presentations of EOAD and EOnonAD Amyloid impacts raw score, primacy, recency, and stopping time Timing-based scores add value over traditional count-based scores.

Abstract
Objective The purpose of the study was to evaluate listening effort in adults who experience varied annoyance towards noise. Materials and methods Fifty native Kannada-speaking adults aged 41-68 years participated. We evaluated the participant's acceptable noise level while listening to speech. Further, a sentence-final word-identification and recall test at 0 dB SNR (less favorable condition) and 4 dB SNR (relatively favorable condition) was used to assess listening effort. The repeat and recall scores were obtained for each condition. Results The regression model revealed that the listening effort increased by 0.6% at 0 dB SNR and by 0.5% at 4 dB SNR with every one-year advancement in age. Listening effort increased by 0.9% at 0 dB SNR and by 0.7% at 4 dB SNR with every one dB change in the value of Acceptable Noise Level (ANL). At 0 dB SNR and 4 dB SNR, a moderate and mild negative correlation was noted respectively between listening effort and annoyance towards noise when the factor age was controlled. Conclusion Listening effort increases with age, and its effect is more in less favorable than in relatively favorable conditions. However, if the annoyance towards noise was controlled, the impact of age on listening effort was reduced. Listening effort correlated with the level of annoyance once the age effect was controlled. Furthermore, the listening effort was predicted from the ANL to a moderate degree.

Abstract
Temporal and semantic associative processes during the acquisition of new verbal information undergo various changes across the life span. Temporal order clusters and subjective clusters were monitored during verbal learning trials using the Rey (Auditory Verbal Learning Task) for 1471 participants aged 8-91. Pairs, three-word, and four-word clusters were measured. Subjective clusters were generated at similar frequency across the whole life span. By contrast, a clear inverted-U curve across life span was indicated for temporal clusters. More words were subjectively clustered than clustered by temporal presentation order. The number of words clustered increased across trials, and cluster types showed a different increase profile across trials. The subjective cluster increment was faster and steeper than the temporal cluster increment in most of the age segments. Life span trajectory tendencies in the formation of temporal and semantic associations in recall were interpreted in relation to different frameworks of cognitive life span changes.

Abstract
The present study demonstrates similarities between route learning and
classical tests of serial order memory. Here, we investigated serial
memory for landmarks in a route learning task, in younger and older
adults. We analysed data from a route learning task with 12 landmarks.
Participants (88 younger and 77 older) learned a route using either a
Fixed Learning (3 exposures to the route) or Flexible Learning
(repeated exposures until successful navigation was achieved)
procedure. Following route learning, participants completed Immediate
Free Recall (IFR) and Free Reconstruction of Order (Free RoO) of the
landmarks. We show clear acquisition of sequence memory for landmarks
for both age groups, with Free RoO producing a bowed serial position
curve. IFR produced recency effects but no primacy effects in fixed
learning, with recency reduced following flexible learning for both
age groups. Younger adults displayed a primacy bias for the first item
recalled in both learning conditions, as did the older adults in the
flexible learning condition. In contrast, older adults displayed a
recency bias in the fixed learning condition. Evidence of contiguity
in IFR was present only for younger adults in the flexible learning
condition. Findings are broadly consistent with results from typical
short-term list learning procedures and support the universality of
sequence learning effects, which we demonstrate are generalisable to a
navigation context.

Abstract
OBJECTIVES Serial position effects have been found to discriminate between normal and pathological aging, and to predict conversion from Mild Cognitive Impairment (MCI) to Alzheimer's disease (AD). Different scoring methods have been used to estimate the accuracy of these predictions. In the current study, we investigated delayed primacy as predictor of progression to early MCI over established diagnostic memory methods. We also compared three serial position methods (regional, standard and delayed scores) to determine which measure is the most sensitive in differentiating between individuals who develop early MCI from a baseline of cognitively intact older adults. METHOD Data were analyzed with binary logistic regression and with receiver-operating characteristic (ROC). Baseline serial position scores were collected using the Rey's Auditory Verbal Learning Test and used to predict conversion to early MCI. The diagnosis of early MCI was obtained through statistical algorithm and consequent consensus conference. One hundred and ninety-one participants were included in the analyses. All participants were aged 60 or above and cognitively intact at baseline. RESULTS The binary logistic regression showed that delayed primacy was the only predictor of conversion to early MCI, when compared to total and delayed recall. ROC curves showed that delayed primacy was still the most sensitive predictor of progression to early MCI when compared to other serial position measures. CONCLUSIONS These findings are consistent with previous studies and support the hypothesis that delayed primacy may be a useful cognitive marker of early detection of neurodegeneration.

Abstract
Mild functional difficulties associated with cognitive aging may be reliably measured by coding "micro-errors" during everyday tasks, like meal preparation. Micro-errors made by 25 older adult and 48 younger adults were coded on four dimensions to evaluate the influence of: 1) poor error monitoring; 2) goal decay; 3) competition for response selection when switching to a new subtask; and 4) interference from distractor objects. Micro-errors made by young adults under a dual task load also were analyzed to determine the influence of overall performance level. Older adults' micro-errors were observed when switching to a new subtask and to unrelated distractors. Slowed error monitoring and goal decay also influenced micro-errors in older adults, but not significantly more so than younger adults under the dual task. Interventions to reduce interference from distractors and to increase attention at critical choice points during tasks may optimize everyday functioning and preclude decline in older adults.

Abstract
The ability to generate memory strategies is a key factor in performance of episodic memory tests. There is evidence about the inefficient use of memory strategies in old adults. However, a question remains unresolved: Worse performance on memory test in the older people is due to an inability to mobilize cognitive strategies or to an episodic memory deficit? In this study we tried to answer it by using the Test of Memory Strategies (TMS), which parametrically reduces the need of executive functions on memory tests. The test consists of five experimental conditions (TMS1-5) where a progressive external organization of the material reduces the need to mobilize memory strategies. TMS was applied to a sample of 180 participants (n = 180) divided into three age groups (25-45; 46-65; 66-85). The results showed an increased performance in all groups groups (F(2, 177) = 14.79, p < .001) across conditions (F(3.88,674.04) = 292.48, p < .001), without group differences in those conditions with a maximum reduction of the need of executive functions (F(7.61,674.04) = 1.95, p = .053). However, middle age and older adults showed more difficulties in establishing cognitive strategies, in the initial conditions. These results lead to the conclusion that the typical pattern of low performance on episodic memory tasks in the older population may be due to the deterioration of executive functions and not mainly to a primary decline of memory process.

Abstract
The acquisition and retention of motor skills is necessary for everyday functioning in the elderly and may be critical in the context of motor rehabilitation. Recent studies indicate that motor training closely followed by sleep may result in better engagement of procedural (“how to”) memory consolidation processes in the elderly. Nevertheless, elderly individuals are mostly morning oriented and a common practice is to time rehabilitation programs to morning hours. Here, we tested whether the time-of-day wherein training is afforded (morning, 8–10:30 a.m., or evening, 6–9 p.m.) affects the long-term outcome of a multi-session motor practice program (10 sessions across 3–4 weeks) in healthy elderly participants. Twenty-nine (15 women) older adults (60–75 years) practiced an explicitly instructed five-element key-press sequence by repeatedly generating the sequence “as fast and accurately as possible.” The groups did not differ in terms of sleep habits and quality (1-week long actigraphy); all were morning-oriented individuals. All participants gained robustly from the intervention, shortening sequence tapping duration and retaining the gains (> 90%) at 1-month post-intervention, irrespective of the time-of-day of training. However, retesting at 7-months post-intervention showed that the attrition of the training induced gains was more pronounced in the morning trained group compared to the evening group (76 and 56.5% loss in sequence tapping time; 7/14 and 3/14 participants showed a > 5% decline in accuracy relative to end of training, respectively). Altogether, the results show that morning-oriented older adults effectively acquired skill in the performance of a sequence of finger movements, in both morning and evening practice sessions. However, evening training leads to a significant advantage, over morning training, in the long-term retention of the skill. Evening training should be considered an appropriate time window for motor skill learning in older adults, even in individuals with morning chronotype. The results are in line with the notion that motor training preceding a sleep interval may be better consolidated into long-term memory in the elderly, and thus result in lower forgetting rates.

Abstract
BACKGROUND Memory and learning, as the core brain function, shows controversial results across studies focusing on aging and dementia. One of the reasons is because of the multi-faceted nature of memory and learning. However, there is still a dearth of comparable proxies with psychometric and morphometric portrait in clinical and non-clinical populations. OBJECTIVE We aim to investigate the proxies of memory and learning function with direct and derived measures and examine their associations with morphometric features in senior adults with different cognitive status. METHODS Based on two modality-driven tests, we assessed the component-specific memory and learning in the individuals with high performing (HP), normal aging, and neurocognitive disorders (NCD) (n = 488). Structural magnetic resonance imaging was used to measure the regional cortical thickness with surface-based morphometry analysis in a subsample (n = 52). METHODS Compared with HP elderly, the ones with normal aging and minor NCD showed declined recognition memory and working memory, whereas had better learning performance (derived scores). Meanwhile, major NCD patients showed more breakdowns of memory and learning function. The correlation between proxies of memory and learning and cortical thickness exhibited the overlapped and unique neural underpinnings. CONCLUSIONS The proxies of memory and learning could be characterized by component-specific constructs with psychometric and morphometric bases. Overall, the constructs of memory are more likely related to the pathological changes, and the constructs of learning tend to reflect the cognitive abilities of compensation.

Abstract
Patient portals (PPs), secure websites that allow patients to access their electronic health records and other health tools, can benefit older adults managing chronic conditions. However, studies have shown a lack of PP use in older adults. Little is known about the way they use PPs in community settings and specific challenges they encounter. The aim of this study was to examine the current state of PP use in older adults, employing baseline data (quantitative and qualitative) from an ongoing nationwide online trial. The dataset includes 272 older adults (mean age, 70.0 years [50-92]) with chronic conditions. Findings showed that the majority of participants (71.3%) were using one or more PPs, but in limited ways. Their comments revealed practical difficulties with managing PPs, perceived benefits, and suggestions for improvement. Further studies with different older adult groups (e.g., clinic patients) will help develop and disseminate more usable PPs for these individuals.
