Control Systems

1.7K
Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Vision01:24

Vision

48.6K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Visual System

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.7K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Area of Science:

  • Psychology of aging
  • Rehabilitation science
  • Ophthalmology

Background:

  • Age-related visual impairment presents significant psychological and behavioral challenges.
  • Understanding adaptation strategies is crucial for effective rehabilitation and healthcare.
  • Existing measures may not adequately capture control strategy use in visually impaired older adults.

Purpose of the Study:

  • To adapt the Optimization in Primary Secondary Control Scale (OPS) for older adults with visual impairment.
  • To create a vision-specific instrument (VIS-OPS) to assess lifespan control strategies.
  • To evaluate the psychometric properties of the new scale.

Main Methods:

  • The original OPS scale was modified to create the vision-specific VIS-OPS.
  • The VIS-OPS was administered to 364 older adults (mean age 82.9 years) with recent vision loss.
  • Confirmatory factor analysis was employed to refine the instrument and validate its structure.

Main Results:

  • A four-factor structure was confirmed for the VIS-OPS after item refinement.
  • The final scale demonstrated good model fit (RMSEA = .06) and acceptable inter-item reliabilities (0.61–0.72).
  • Correlational analyses supported the criterion-related validity of VIS-OPS with disability and psychosocial functioning.

Conclusions:

  • The VIS-OPS is a valid and reliable tool for assessing control strategy use in visually impaired older adults.
  • This scale facilitates systematic measurement of adaptations to vision loss.
  • The VIS-OPS can serve as a model for developing similar measures for other disabilities.
