Interactions of visual and cognitive stress
Optometry - Journal of the American Optometric Association, 2011The objective of this research is to assess the ocular and muscular response to long-duration reading under different visual and cognitive difficulty levels.Thirty-five subjects, with 20/20 vision and without history of ocular pathology or cognitive deficits, participated in the study.

Visual art permeates several aspects of daily life and has historically been associated with pleasure and positive emotions (Robinson, 2004). Through these positive emotions, it could improve health parameters, but so far results remain scarce. To expand the research about the effects of visual art on individual health and well-being, this study ...

Binocular Vision without Visual Stress
Optometry and Vision Science, 1989ABSTRACT The use of changes in fixation disparity, the associated phoria, and the dissociated phoria in assessing the degree of visual stress requires that we know the effect of vision under close working conditions (40 cm) on these parameters.

Evidence for Overlapping Visual Processing Difficulties in Adult ADHD and Visual Stress
Perceptual and Motor Skills, 2023We investigated the viability of spectral filters as an adjunctive treatment for adults with both ADHD and visual processing difficulties. Fifty-nine adults (age 18-50), diagnosed with both ADHD and visual stress received either spectral filters ( n = 39) or no intervention ( n = 20) to address visual processing difficulties.

Visual imagery in posttraumatic stress disorder
Journal of Traumatic Stress, 1996AbstractVisual imagery is reported to play a central role m posttraumatic stress disorder (PTSD). This pilot investigation examined visual imagery ability in patients with varying degrees of posttraumatic stress. Eighty one survivors of motor vehicle accidents with either (a) diagnosed PTSD, (b) diagnosed Specific Phobia, or (c) no psychiatric ...

Time Stress and the Processing of Visual Displays
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1992Selecting the appropriate display format for time-constrained tasks is the focus of the research presented in this paper. The effect of time stress on operator performance was assessed by manipulating the time available to process the display. Twenty people were trained as operators and instructed to identify the state of a system using either a ...

Advances in Space Research, 1994
Abstract In a structure as indeterminate as a partially inflated balloon it is very difficult to determine either the stress at any given point or a stress pattern over an area. Finite element analysis for this purpose is under development, but this will not likely bear fruit for years.

VISUALIZING DIRECTIONAL STRESSES IN A STRESS TENSOR FIELD
2006Tensors represent a natural means for describing many physical phenomena. Therefore, there is a need to develop methods that will assist in analyzing such data. Despite some calls for generality, we concentrate on quite a specific application because general methods designed for visualizing information contained in second order tensor fields may fail ...

An innovative approach to visualization of stress
31st Annual Frontiers in Education Conference. Impact on Engineering and Science Education. Conference Proceedings (Cat. No.01CH37193), 2002This paper describes the development of a tool to help students easily visualize stresses in truss structures through photoelastic visualization of quickly assembled truss structures. Clear polymer structural members of varying lengths were designed with the capability to be connected to form a variety of simple truss structures.

The Effect of Colored Lenses on the Visual Evoked Response in Children With Visual Stress
Optometry and Vision Science, 2006ABSTRACT Purpose. Some children with visual stress and/or headaches have fewer symptoms when wearing colored lenses. Although subjective reports of improved perception exist, few objective correlates of these effects have been established.
