The Digit Span test is a widely used working memory measure. However, when using standardized scoring procedures, previous studies have demonstrated inconsistent relationships between Digit Span subtests and working memory measures frequently used in cognitive psychology experiments. Partial scoring involves awarding credit for all digits recalled in the correct serial location, whereas traditional scoring involves only awarding credit for a trial if all digits are recalled in the correct serial location. The current study compared the traditional all-or-nothing scoring method and the partial scoring method on Digit Span with other working memory measures and with measures of general fluid intelligence. The results showed that when differences were found, partial scoring was associated with stronger relationships with Digit Span Backwards but weaker relationships with Digit Span Forward and Sequencing compared with traditional scoring. These results support previous findings identifying differences between the Digit Span subtests and the utility of examining traditional scoring procedures.

Apolipoprotein () genotype and nitric oxide (NO) deficiency are risk factors for age-associated cognitive decline. The oral microbiome plays a critical role in maintaining NO bioavailability during aging. The aim of this study was to assess interactions between the oral microbiome, NO biomarkers, and cognitive function in 60 participants with mild cognitive impairment (MCI) and 60 healthy controls using weighted gene co-occurrence network analysis and to compare the oral microbiomes between carriers and noncarriers in a subgroup of 35 MCI participants.

Introduction: The study of attention has been pivotal in advancing our comprehension of cognition. The goal of this study is to investigate which EEG data representations or features are most closely linked to attention, and to what extent they can handle the cross-subject variability.
Methods: We explore the features obtained from the univariate time series from a single EEG channel, such as time domain features and recurrence plots, as well as representations obtained directly from the multivariate time series, such as global field power or functional brain networks.

Few performance validity tests exist for youth undergoing baseline testing for the management of sport-related concussion. This study provides an initial validation of a reliable span calculation from the Wechsler Intelligence Scale for Children-Fourth Edition Letter-Number Sequencing (LNS) subtest as a performance validity indicator for youth baseline testing (Reliable Letter-Number Span; RLNS). Youth athletes ( = 173) underwent baseline concussion testing for the management of sport-related concussion.

A nutritious diet is crucial for good health and cognitive function, including working memory (WM). Nutrients like omega-3 fatty acids, antioxidants, and vitamins found in whole foods have been linked to improved WM. Examining the impact of dietary habits on WM in women, who face hormonal and health-related challenges, is important.

Background: FAO/WHO introduced food-based dietary guidelines (FBDG) to promote healthy dietary habits. To translate the FBDG, optimized food-based recommendations (FBR) can be developed using linear programming (LP) to address problem nutrients. Despite the importance of local-specific FBR for anemia prevention, no study has reported the effect of nutrition education which promoted FBR in adolescent girls.
