Assessment of spatial neglect in clinical practice: A nationwide survey.

This study was part of a nationwide, anonymous, open Internet survey conducted amongst healthcare professionals in Denmark on the assessment and treatment of spatial neglect (SN). The objective was to describe knowledge and practices in the assessment of SN in current clinical practice across different healthcare sectors and professions. Data included the perceived prevalence, assessment methods and observations, subtypes and differential diagnostics of SN.

The computerized cognitive training alliance - A proposal for a therapeutic alliance model for home-based computerized cognitive training.

Background: To increase the number of hours available for cognitive rehabilitation, it may be an option to use the spouse or paid assistants to assist with computerized home training. However, the delegation of training responsibilities may affect the normal roles of the therapist, the spouse and the training assistants.

Objective: This article suggests a new model for understanding the impact of computerized home training on the therapeutic alliance between the therapist, the patient and training assistants.

Treatment of spatial neglect in clinical practice: A nationwide survey.

Objectives: Clinical research has documented a range of evidence-based treatment approaches for spatial neglect (SN), but there is a lack of research on the implementation of treatment into clinical practice. The purpose of this study is to describe the current clinical practice of SN treatment across healthcare sectors including involved professions, methods, timing and sources of evidence.

Material And Methods: This is the second part of a nationwide, anonymous, open Internet survey that was conducted among healthcare professionals in Denmark on assessment and treatment of SN.

Simulated prism exposure in immersed virtual reality produces larger prismatic after-effects than standard prism exposure in healthy subjects.

Previous studies have shown that the size of the leftward bias after exposure to rightward prism-deviation (the prismatic after-effect) depends on the degree of rightward prism-deviation as well as the type of visual feedback receives during exposure to prism-deviation. In this study, we tested if it was possible to obtain a leftward bias in pointing precision using two different methods of creating diverted visual input by simulating a rightward prism diversion of visual input in immersive virtual reality. We compared the results to the leftward bias in pointing precision obtained after exposure to standard prism goggles deviating visual input 10 degrees to the right.

Cognitive aging on latent constructs for visual processing capacity: a novel structural equation modeling framework with causal assumptions based on a theory of visual attention.

We examined the effects of normal aging on visual cognition in a sample of 112 healthy adults aged 60-75. A testbattery was designed to capture high-level measures of visual working memory and low-level measures of visuospatial attention and memory. To answer questions of how cognitive aging affects specific aspects of visual processing capacity, we used confirmatory factor analyses in Structural Equation Modeling (SEM; Model 2), informed by functional structures that were modeled with path analyses in SEM (Model 1).

Normative perceptual estimates for 91 healthy subjects age 60-75: impact of age, education, employment, physical exercise, alcohol, and video gaming.

Visual perception serves as the basis for much of the higher level cognitive processing as well as human activity in general. Here we present normative estimates for the following components of visual perception: the visual perceptual threshold, the visual short-term memory (VSTM) capacity and the visual perceptual encoding/decoding speed (processing speed) of VSTM based on an assessment of 91 healthy subjects aged 60-75. The estimates were modeled from input from a whole-report assessment based on a theory of visual attention.

Intensive video gaming improves encoding speed to visual short-term memory in young male adults.

The purpose of this study was to measure the effect of action video gaming on central elements of visual attention using Bundesen's (1990) Theory of Visual Attention. To examine the cognitive impact of action video gaming, we tested basic functions of visual attention in 42 young male adults. Participants were divided into three groups depending on the amount of time spent playing action video games: non-players (<2h/month, N=12), casual players (4-8h/month, N=10), and experienced players (>15h/month, N=20).

Dissimilar outcomes of apparently similar procedures as a challenge to clinical neurorehabilitation and basic research: when the same is not the same.

In the study of the brain and how it adapts to changes or injury, researchers sometimes come across situations where apparently similar types of tests or training do not achieve similar outcome results. This is true, in particular, within the field of computer-based rehabilitation where paper-and-pencil tests and training is converted to computer. This paper raises the attention to the fact that supposedly similar settings may not, in fact, elicit similar results and caution therapists and researchers who work with rehabilitation of brain injury.

Indirect versus direct feedback in computer-based Prism Adaptation Therapy.

Prism Adaptation Therapy (PAT) is an intervention method in the treatment of the attention disorder neglect (Frassinetti, Angeli, Meneghello, Avanzi, & Ladavas, 2002; Rossetti et al., 1998). The aim of this study was to investigate whether one session of PAT using a computer-attached touchscreen would produce similar after-effects to the conventional box normally used in PAT.
