OBJECTIVES: Academic difficulties are common in children with epilepsy, although little is known about the effect of various seizure-related and cognitive variables. Given that persistent seizures may negatively impact academics, and that working memory is predictive of academic abilities, we examined the effects of recent seizures and working memory on word reading, spelling, and arithmetic in pediatric epilepsy. We hypothesized that persistent seizures would be associated with lower working memory ability, which would in turn result in poorer academic performance...

Acoustic stimulation methods applied during sleep in young adults can increase slow wave activity (SWA) and improve sleep-dependent memory retention. It is unknown whether this approach enhances SWA and memory in older adults, who generally have reduced SWA compared to younger adults. Additionally, older adults are at risk for age-related cognitive impairment and therefore may benefit from non-invasive interventions. The aim of this study was to determine if acoustic stimulation can increase SWA and improve declarative memory in healthy older adults...

In immediate serial recall, it is well established that performance is influenced by lexical factors such as imageability and word frequency. However, when participants are asked to recall the to-be-remembered items in their reverse order, known as backward recall, lexical factors produced contradictory findings. In 4 experiments, we tested the role of response modality in modulating the effects of imageability and word frequency in backward recall. The magnitude of the 2 tested lexical factors was only slightly reduced in backward compared with forward recall when participants responded manually...

Study Objectives: In young adults, napping is hypothesized to benefit episodic memory retention (e.g., via consolidation). Whether this relationship is present in older adults has not been adequately tested, but is an important question because older adults display marked changes in sleep and memory. Design: Between-subjects design. Setting: Sleep laboratory at Emory University School of Medicine. Participants: 50 healthy young adults (18-29) and 45 community dwelling older adults (58-83)...

There is debate as to whether the neurocognitive changes associated with HIV infection represent an acceleration of the typical aging process or more simply reflect a greater accentuated risk for age-related declines. We aimed to determine whether accelerated neurocognitive aging is observable in a sample of older HIV-infected individuals compared to age-matched seronegatives and older old (i.e., aged ≥65) seronegative adults. Participants in a cross-sectional design included 48 HIV-seronegative (O-) and 40 HIV-positive (O+) participants between the ages of 50-65 (mean ages = 55 and 56, respectively) and 40 HIV-seronegative participants aged ≥65 (OO-; mean age = 74) who were comparable for other demographics...

Although Alzheimer's disease criteria promote the use of biomarkers, their maturity in clinical routine still needs to be assessed. In the light of the oncology framework, we conducted a literature review on measures used to assess delayed recall impairment due to medial temporal lobe dysfunction (i.e., free and cued word list recall tests). Ample evidence is available for phases 1 (rationale for use), 2 (discriminative ability), and 3 (early detection ability) for many of the tests in routine use. Evidence about phase 4 (performance in real world) and phase 5 (quantify impact and costs) is yet to come...

The importance of memory consolidation in integrating new knowledge has received much recent attention in the field of word learning. Less examined is the change in existing word knowledge as a result of learning, which we hypothesize to occur prior to the opportunity for consolidation. To test this, we had participants learn new meanings for known words and novel words. Then they performed a one-back task on a list of words that included the trained words followed by words that probed either their new or original meanings while EEGs were recorded...

This study was designed to examine the clinical utility of critical items within the Recognition Memory Test (RMT) and the Word Choice Test (WCT). Archival data were collected from a mixed clinical sample of 202 patients clinically referred for neuropsychological testing (54.5% male; mean age = 45.3 years; mean level of education = 13.9 years). The credibility of a given response set was psychometrically defined using three separate composite measures, each of which was based on multiple independent performance validity indicators...

The adaptive view of human memory (Nairne, 2010) assumes that animates (e.g., rabbit) are remembered better than inanimates (e.g., glass) because animates are ultimately more important for fitness than inanimates. Previous studies provided evidence for this view by showing that animates were recalled or recognized better than inanimates (e.g., Nairne, VanArsdall, Pandeirada, Cogdill, & LeBreton, 2013), but they did not assess memory for contextual details (e.g., where animates vs. inanimates occurred). In this study, we tested recollection of spatial information (Study 1) and temporal information (Study 2) associated with animate versus inanimate words...

Rotating a scene in a frontoparallel plane (rolling) yields a change in orientation of constituent images. When using only information provided by static images to perceive a scene after orientation change, identification performance typically decreases (Rock & Heimer, 1957). However, rolling generates optic flow information that relates the discrete, static images (before and after the change) and forms an embodied memory that aids recognition. The embodied memory hypothesis predicts that upon detecting a continuous spatial transformation of image structure, or in other words, seeing the continuous rolling process and objects undergoing rolling observers should accurately perceive objects during and after motion...

BACKGROUND: Serum uric acid (SUA) may protect against free radical stress damage and was previously linked to cognitive impairment in older adults, but evidence in middle-aged adults is scarce. PURPOSE: We sought to analyze whether SUA is associated with cognitive performance in apparently healthy middle-aged participants in the ELSA-Brasil cohort study. METHODS: We excluded participants older than age 65, those taking allopurinol, benzbromarone, or medications that could impair cognitive performance, those with previous stroke, and those with incomplete data on cognitive tests or SUA...

OBJECTIVE: Both estrogen and exercise may have cognition enhancing benefits; however, young oligomenorrheic/amenorrheic athletes (OA) with estrogen deficiency have not been evaluated for cognitive deficits. Our objective was to determine whether 6 months of estrogen replacement will impact cognitive domains in OA. We hypothesized that estrogen replacement would improve verbal memory and executive control in OA. METHODS: We performed cognitive assessments at baseline and after 6 months in 48 OA (14-25 years) randomized to estrogen (EST+) (oral 30 µg ethinyl estradiol [n = 16] or transdermal 100 µg 17-β-estradiol patch [n = 13]) or no estrogen (EST-) (n = 19) in an ongoing clinical trial...

This study aimed to evaluate the effects of different types of exercise on memory performance and memory complaint after 12-week intervention. Eighty community-dwelling volunteers, aged 66.96 ± 11.73 years, were randomly divided into four groups: resistance, cardiovascular, postural and control groups (20 participants for each group). All participants were tested for their cognitive functions before and after their respective 12-weeks intervention using Rey memory words test, Prose memory test, and Memory Complaint Questionnaire (MAC-Q)...

Children with intellectual disabilities (ID) or borderline intellectual disabilities (BIF) often demonstrate impairments in executive functioning (EF). Studies in typically developing children show that aerobic fitness (AF) is positively related with EF. Skill-related physical fitness (SF) might, however, be a stronger predictor of EF than AF, as cognitive challenges are inherent in application of these skills. In this study, AF and SF were examined simultaneously in relationship with domains of EF in children with ID or BIF...

Hierarchical control of skilled performance depends on chunking of several lower-level units into a single higher-level unit. The present study examined the relationship between chunking and recognition of trained materials in the context of typewriting. In 3 experiments, participants were trained with typing nonwords and were later tested on their recognition of the trained materials. In Experiment 1, participants typed the same words or nonwords in 5 consecutive trials while performing a concurrent memory task...

Contrasting results in visual and auditory spatial memory stimulate the debate over the role of sensory modality and attention in identity-to-location binding. We investigated the role of sensory modality in the incidental/deliberate encoding of the location of a sequence of items. In 4 separated blocks, 88 participants memorised sequences of environmental sounds, spoken words, pictures and written words, respectively. After memorisation, participants were asked to recognise old from new items in a new sequence of stimuli...

INTRODUCTION: The Recognition Memory Test (RMT) and Word Choice Test (WCT) are structurally similar, but psychometrically different. Previous research demonstrated that adding a time-to-completion cutoff improved the classification accuracy of the RMT. However, the contribution of WCT time-cutoffs to improve the detection of invalid responding has not been investigated. The present study was designed to evaluate the classification accuracy of time-to-completion on the WCT compared to the accuracy score and the RMT...
