Visual System (integrity, efficiency, information process) Flashcards
Visual system 3 broad components:
Visual Integrity
Visual Efficiency
Visual Information processing
visual system that pertains to:
- Eye health and Refractive Status
- Normal Development of the visual system
Visual Integrity
the input channel for visual information as it travels to our brain to be processed and used for effective:
reading
writing
other academic task
Visual Efficiency
Visual Efficiency includes:
- Oculomotor function
- Accommodation and Convergence
- Sensory fusion abilities
refers to the visual cognitive skills that allow us to process and interpret meaning from the visual information that we gain through our eyesight
Visual Information processing
awareness of one’s own position in space relative to other objects,
ability to identify position of two or more objects in relation to oneself or in relation to each other
Visual SPATIAL skill
Classifications of Visual Spatial Skills:
- Bilateral Integration
- Laterality
- Directionality
- Directionality for numbers and Letters
awareness and use of the extremities
both separately and simultaneously in unilateral and bilateral combinations
Bilateral Integration
the skill of being self-aware of two sides of the body and perceiving them as different from one another
LATERALITY
incorporates up, down, ahead, behind movements or any combination
Directionality
SKILLS that includes:
visual discrimination
visual memory
visual-spatial relationship
form constancy
visual sequential memory
figure ground
visual closure
VISUAL PERCEPTUAL SKILLS
the ability to identify the position of two or more visual stimuli in relation to oneself or in relation to each other
VISUAL SPATIAL relationship/skill
the ability to remember and recall a sequence of visual images such as letters numbers. images and symbols in a correct order
Sequential memory
ability to identify differences and similarities between objects
by analyzing their individual characteristics and distinctive features
Visual Discrimination
the ability to know that a form or shape is the same, despite the changes in size, orientation, color and sequence
Form constancy
ability to recognize or recall previously presented visual stimuli, whether individual or grouped in a specific sequence
ability to remember what is seen for immediate recall
Visual Memory
ability to locate and identify shapes and objects embedded in a busy visual environment
ability to filter visual information that is not important so that you can focus on the relevant visual information
Visual Figure-ground
ability to see a complete figure out of broken or fragmented images
ability to recognize any given stimulus from an incomplete presentation
VISUAL CLOSURE
the brain’s ability to make sense of what the eyes see
it is important for every activities such as dressing, eating, writing and playing
Visual PERCEPTUAL skills
