Study Notes

Visual Processing Concepts

  • Binocular advantage: Enhanced depth perception and spatial awareness gained from using both eyes instead of one.
  • Cones: Specialized photoreceptors functioning in bright light; critical for detecting fine details and colors. There are three types: S (blue), M (green), and L (red), enabling full color vision through their combined sensitivity.
  • Contrast: The perceived difference in light intensity and quality between two close locations, essential for visual clarity.

Visual Adaptations and Mechanisms

  • Contrast gain: Adjustment of the visual system's sensitivity, optimizing perception based on prevalent environmental contrast levels.
  • Dark adaptation: The process through which the eyes enhance sensitivity to low light conditions, facilitating vision when illumination is minimal.
  • Lateral inhibition: A mechanism where one neuron's signal suppresses the activity of neighboring neurons, improving edge detection in visual perception.

Color Vision Theories

  • Opponent Process Theory: Proposes four primary colors organized into two opposing pairs (red/green, blue/yellow) with an additional black/white pair responsible for light contrast perception.
  • Trichromacy theory: Suggests color perception arises from the combination of signals from three distinct cones; the foundation of human color vision.

Brain Regions and Reflexes

  • Primary visual cortex (V1): Located in the occipital lobe, it processes fundamental visual attributes such as line orientation, color, and motion at a basic level.
  • Vestibulo-ocular reflex: Integrates motion and visual information to stabilize gaze on objects during head or body movement.

Attention and Perception

  • What pathway: Neural pathways dedicated to object recognition, helping understand the identity of visual stimuli.
  • Where-and-How pathway: Focuses on spatial awareness and interaction with objects, guiding physical actions based on their locations.
  • Dichotic listening: An experimental method where different auditory messages are presented to each ear to study selective attention.
  • Divided attention: The capacity to distribute focus among multiple tasks simultaneously, highlighting cognitive flexibility.
  • Inattentional blindness: A phenomenon where obvious stimuli go unnoticed due to focused attention on a different task.
  • Limited capacity: Humans have finite attentional resources that restrict simultaneous processing of multiple cognitive tasks.
  • Selective attention: The process of choosing specific stimuli to concentrate on, effectively filtering out distractions.
  • Shadowing: A task requiring repetition of an auditory message, useful in studying attention and information processing.
  • Subliminal perception: Refers to the ability to understand and process information without conscious awareness.
