Frontiers in Aging Neuroscience, 2021 Background: Various working memory (WM) trainings have been tested, but differences in experimental designs, the lack of theoretical background, and the need of identifying task-related processes such as filtering efficiency limit conclusions about their

On the factors causing processing difficulty of multiple-scene displays [PDF]
, 2016 Multiplex viewing of static or dynamic scenes is an increasing feature of screen media. Most existing multiplex experiments have examined detection across increasing scene numbers, but currently no systematic evaluation of the factors that might produce ...

Working Memory Capacity and Redundant Information Processing Efficiency
Frontiers in Psychology, 2015 Working memory capacity (WMC) is typically measured by the amount of task-relevant information an individual can keep in mind while resisting distraction or interference from task irrelevant information.

On the relationship between cognitive load and the efficiency of distractor rejection in visual search: The case of motion-form conjunctions [PDF]
Visual Cognition, 2021 Search for a target defined by a conjunction of movement and shape (a moving X amongst moving O and static Xs) is performed efficiently, with static distractors contributing little to observed RT. How search may be restricted to the moving items, whilst static items are ignored is not fully understood.

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Neural correlates of learning to attend
Frontiers in Human Neuroscience, 2010 Recent work has shown that training can improve attentional focus. Little is known, however, about how training in attention and multitasking affects the brain. We used functional magnetic resonance imaging (fMRI) to measure changes in cortical responses

Effects of age and eccentricity on visual target detection [PDF]
, 2013 The aim of this study was to examine the effects of aging and target eccentricity on a visual search task comprising 30 images of everyday life projected into a hemisphere, realizing a ±90° visual field.

Item Analysis: The impact of distractor efficiency on the discrimination power of multiple choice items [PDF]
, 2019 Abstract Background Distractor efficiency of multiple choice item responses is a component of item analysis used by the examiners to to evaluate the credibility and functionality of the distractors.Objective To evaluate the impact of functionality (efficiency) of the distractors on difficulty and discrimination indices.Methods A cross-sectional

Advanced Robotics Research, EarlyView.Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...
