Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.5K
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.

Visual Agnosia01:12

Visual Agnosia

1.5K
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Tactile and Chemical Senses01:27

Tactile and Chemical Senses

1.2K
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Design Example: Resistive Touchscreen

828
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Perception01:28

Perception

1.6K
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Vision01:24

Vision

60.9K
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.

Area of Science:

  • Neuroscience
  • Sensory Perception
  • Cognitive Science

Background:

  • The nervous system integrates multisensory information for environmental interaction.
  • Cross-modal interactions, particularly between touch and vision, can occur unconsciously.

Purpose of the Study:

  • To investigate if haptic signals interact with visual signals outside of visual awareness using continuous flash suppression (CFS).
  • To determine if congruent touch accelerates visual stimuli into consciousness.

Main Methods:

  • Utilized continuous flash suppression (CFS) to render visual gratings invisible.
  • Measured suppression durations of visual gratings during visual-only and visuo-haptic stimulation.
  • Compared suppression durations with congruent and incongruent haptic gratings.

Main Results:

  • Active exploration of a congruent haptic grating reduced visual suppression durations compared to visual-only stimulation.
  • The facilitatory effect of touch disappeared when visual and haptic gratings were mismatched in orientation or spatial frequency.
  • Congruent touch accelerated the rise of suppressed visual stimuli to consciousness.

Conclusions:

  • Unconscious cross-modal interactions between vision and touch depend on visuo-haptic congruency.
  • Visuo-haptic interactions can occur at early stages of cortical processing, as suggested by CFS findings.
