Age-Differential Role of Gaze Reinstatement in Recognition Memory for Negative Visual Stimuli.

Objectives: Although research has shown that the replay of encoding-specific gaze patterns during retrieval, known as gaze reinstatement, facilitates memory retrieval, little is known about whether it differentially associates with the negativity preference in memory (defined as enhanced memory for negative stimuli relative to neutral stimuli in this study) among younger and older adults. The present study aims to address this research gap.

Methods: A total of 33 older adults (16 women; aged 58-69 years, M = 63.

A self-supported sodium alginate composite hydrogel membrane and its performance in filtering heavy metal ions.

A novel self-supported polysaccharide based hydrogel membrane was prepared by adding cellulose nanofiber (CNF) and micron-sized biochar (BC) into sodium alginate (SA) hydrogel with in-situ free water evaporation ("cooking") process and ionic crosslinking, in which the polyethylene glycol (PEG) was used as a pore-forming agent. Herein, CNF can not only enhance the mechanical property of the matrix, but also assist the homogeneous dispersion of BC. As a result, the prepared membrane had a maximum tensile strength of up to 5.

Cognitive training modified age-related brain changes in older adults with subjective memory decline.

Objectives: Neuroimaging findings suggest that older adults with subjective memory decline (SMD) demonstrate some neurodegenerative brain changes and have high risk of developing dementia, but relatively little is known about the effectiveness of interventions for SMD. This study aimed to examine the effects of cognitive training on resting-state brain activity in SMD.

Method: This study employed the amplitude of low frequency fluctuations (ALFF) and resting state functional connectivity (rs-FC) analyses.

Time Unpacking Effect on Intertemporal Decision-Making: Does the Effect Change With Choice Valence?

People often feel that a period of time becomes longer when it is described in more detail or cut into more segments, which is known as the time unpacking effect. The current study aims to unveil how time unpacking manipulation impacts intertemporal decision making and whether the gain-loss valence of choices moderates such impacts. We recruited 87 college students (54 female) and randomly assigned them to the experimental conditions to complete a series of intertemporal choice tasks.

Social Support and the Incidence of Cognitive Impairment Among Older Adults in China: Findings From the Chinese Longitudinal Healthy Longevity Survey Study.

Objective: Social support shows a protective effect against cognitive impairment in older adults. However, the longitudinal relationship between the distinct sources of social support and the incidence of cognitive impairment remains unclear. This study aims to investigate the association between different sources of social support and the incidence of cognitive impairment among older adults in China.
