Alzheimer's Disease is the most prevalent neurodegenerative disease, and is a leading cause of disability among the elderly. Eye movement behaviour demonstrates potential as a non-invasive biomarker for Alzheimer's Disease, with changes detectable at an early stage after initial onset. This paper introduces a new publicly available dataset: EM-COGLOAD (available at https://osf.

Objectives: The primary aim of this review was to investigate neurocognitive outcomes following out-of-hospital cardiac arrest (OHCA). Specifically, the focus was on identifying the different neurocognitive domains that are assessed, the measures used, and the level of, and criteria for, impairment.

Design And Review Methods: A systematic review of the literature from 2006 to 2021 was completed using Medline, Cinahl and Psychinfo.

Emotional deception and emotional attachment are regarded as ethical concerns in human-robot interaction. Considering these concerns is essential, particularly as little is known about longitudinal effects of interactions with social robots. We ran a longitudinal user study with older adults in two retirement villages, where people interacted with a robot in a didactic setting for eight sessions over a period of 4 weeks.

We examined the extent to which individual differences contribute to performance in a task considered to index implicit learning, the Hebb Digits task. Although Hebb Digits learning is considered to be equivalent for those with implicit and explicit knowledge of the repeating digit pattern, this study found that participants who developed explicit knowledge showed learning, whereas those without explicit knowledge did not. Additionally, participants who developed explicit knowledge outperformed participants without explicit knowledge on working memory measures, specifically the Automated Operation Span Task total correct score and absolute score.

This study examined the predictive validity of widely utilized neuropsychological tests, the Cognitive Behavioral Driving Inventory (CBDI) and the Useful Field of View (UFOV), to predict driving abilities in a community-dwelling older adult population. Thirty-nine older adults were given the test battery and an on-the-road driving test. Results indicated that while performance on both the CBDI and UFOV was significantly predictive of driving performance, neuropsychological tests of executive function, memory, and visual perception were more predictive of on-the-road driving ability.

Neuropsychological studies suggest a subclinical impairment in executive function that occurs with normal aging. This is the first study to examine the performance of healthy older adults on the Tower of London-Revised (TOL-R), as well as the relationship between TOL-R performance and verbal and nonverbal abilities. Performance of 63 older adult participants on the TOL-R and two WAIS-III subtests was compared to that of 35 young adult college students.

The current study examined the contributions of general slowing and frontal decline to age differences in fluid intelligence. Participants aged 20-89 years completed Block Design, Matrix Reasoning, simple reaction time, choice reaction time, Wisconsin Card Sorting, and Tower of London tasks. Age-related declines in fluid intelligence, speed of processing, and frontal function were observed.

The contributions of working memory, inhibition, and fluid intelligence to performance on the Tower of Hanoi (TOH) and Tower of London (TOL) were examined in 85 undergraduate participants. All three factors accounted for significant variance on the TOH, but only fluid intelligence accounted for significant variance on the TOL. When the contribution of fluid intelligence was accounted for, working memory and inhibition continued to account for significant variance on the TOH.
