Visual Processing refers to the manipulation of what we see; not actual vision but the processing of visual information by the brain. It is an individual’s ability to think about visual patterns and visual stimuli. Visual processing is the synthesis of various visual processing skills, including:
Visual Discrimination- the ability to differentiate objects based on their individual differences
Spatial Relations- the ability to perceive the positions of objects in relation to oneself and/or other objects (e.g., figure reversals or rotations).
Visual Form Constancy- the ability to mentally manipulate forms and visualize the resulting outcomes; reflects the student’s ability to recognize forms, letters, or words regardless of their orientation.
Visual Figure Ground- the ability to identify an object from a complex background or surrounding objects; and to attend to one activity without being distracted by other surrounding stimuli.
Visual Closure- the ability to identify a whole figure when only fragments are presented.
Examples of Overall Difficulties:
Misunderstanding or confusing written symbols
Trouble differentiating colors
Trouble differentiating similarly shaped letters and numbers
Difficulty identifying information from pictures, charts, graphs, maps, etc.
Weaknesses organizing information from different sources into one cohesive document
Difficulty finding specific information on a printed page
Difficulty putting parts together to form a whole (ex. maps, 3-dimensional objects)
Problems with being easily distracted by competing visual information
Overall Strategies
Provide activities designed to develop discrimination of visual features (ex. Where’s Waldo?; Bingo; find the odd one out; hidden objects; circle the same word in a text; word searches; find words ending in __; find words containing the vowel blend ___)
Find “busy” pictures and have the student look for different people and objects
Color by number
Build puzzles but instead of starting with the border start with a particular section and then build from there
Teach the student learn how to keep his/her desk clear of distractions
Write several letters or words that have reversals on the board. Ask the student to find them, wipe them away and form them correctly
Model, teach, and encourage the use of verbal rehearsal, thinking out loud, and/or subvocalization
Sequence several pictures, letters, words or playing cards on the wall. Give the student identical cards to arrange in the same sequence on the table. Looking back and forth between vertical and horizontal surfaces prepares students to copy from the board
Teach student to use finger or pencil to guide eyes to follow the text in the sentence
Build skills by having student complete sorting activities, puzzles, ordering activities, matching activities, etc.
Accommodations

Place a colored place mat under the materials the student is working on
Use a red marker to outline boundaries for coloring, mazes or cutting tasks
Place only one activity on a page

Confusion of similarly shaped letters, numbers, math signs
Difficulty understanding that certain numbers go together as a unit 14 instead of 1 and 4 and that operational signs (+, x, =) are distinct from numbers. (In math the only clue is spacing).
Difficulty relating to directional problems in math (up-down-addition), left-right (regrouping)
Difficulty aligning of numbers on the page
Difficulty using a number line
Failing to notice size differences in shapes
Difficulty visualizing geometric forms
Difficulty visualizing proportion
Math Strategies
Teach student to verbalize the math problem
Teach student to use technology to help with graphing, writing, etc. (Desmos, Winplot, etc.)
Help the student find a useful visual strategy such as webs, diagrams, charts and schemas for math operations
Accommodations
Use graph paper to aid in aligning numbers
Clearly space words/problems on a page
Highlight useful information while demonstrating word problems
Outline boundaries
When working on a chalkboard or whiteboard, make sure it is erased well to minimize visual clutter
Use colored pencils to outline two-dimensional figures on a background
Use color to highlight differences in signs, variables, and numbers
When graphing, or using color to present information, use highly contrasting colors
Use high contrast graph paper and grids
Use graphic organizers to sequence information
Vary teaching methods: Provide verbal explanations with visual guides and use oral presentations along with reading
Color code words on visual notes
Color code math problems/equations
Color code written instructions
Clearly space objects on a page/provide white space on the page
Allow students to write answers directly on a test
Use a ruler as a reading or alignment guide
Use an index card or marker when reading or doing work to blot out distraction of other words/images
Reduce or eliminate the amount of copy work-provide copies of notes
When copying is required, do not require speed. Allow extra time for the student to proofread for accuracy
Reduce the number of visual displays involving manipulatives, drawings, diagrams and charts. Replace them with clear verbal instructions
Replace copying from the blackboard with providing copies of the notes or assignments
When copying is required, do not require speed. Allow extra time for the student to proofread for accuracy
Provide math exercises on worksheets with only a few questions and plenty of white space.
Examples of Reading Difficulties
Difficulty finding and retaining important information in reading assignments or tests
Difficulty reading with speed and precision
Problems visually blending letters into words
Problems perceiving individual letters or words accurately
Weaknesses in noticing all the relevant words in a question, identifying key words, and/or developing “skim and scan” skills
Problems with skipping lines of text
Difficulty tracking from left to right
Difficulty tracking while reading
Difficulty with letter identifications (m looks like n & p looks like q, difference between inl and imp is difficult)
Reversing letters and transposing words (saw-was) may occur
Omissions, and additions while reading may occur
Reading Strategies
Teach common visual patterns within words (e.g., prefixes and suffixes)
Highlight useful information while reading
When choosing books for young children, find books containing pictures that are not too ‘busy’. Young children especially in the first year need simply drawn picture books. Try finding books with photographs of objects on a white background. This will help the child connect the 3D with the 2D, and will not have a distracting background. Once they easily recognize photographs, only then should abstract drawings and paintings be introduced
Focus on the most frequently misperceived words and point out differences to develop this skill
Make flash cards with a correct letter on one side and an incorrectly formed letter on the other side. Have the student try to draw the letter correctly, then turn over the card to see if it is right. Have them write in sand or with finger paint to make it more fun.
Some helpful activities for building an understanding of individual sounds:
Say and push: The teacher dictates a word such as bat. The student uses manipulatives (buttons, cubes, counters, etc.) to push for each sound in the word. The teacher should stretch the word out when dictating (baaaaaaaaat). The student should push a manipulative (counter) up for each sound they hear. It may be necessary for the teacher to demonstrate.
Say and tap: the teacher dictates a word. The student taps, claps, hops, etc. for each sound they hear in the word. The teacher may need to demonstrate until the student has an understanding.
Have students clap the syllables in a word.
Offer repeated exposure to the letter-sound relationships he/she does not know. This should be quick-paced and frequent.
Accommodations
Create a “window” made from cutting a rectangle in an index card to help keep the relevant words, sentences, etc. in clear focus while blocking out much of the peripheral material which can become distracting
Use an index card or marker when reading to blot out distraction of other words
Use a ruler or other straightedge to help keep relevant words, sentences in focus, while blocking out the peripheral material
Use color overlays for reading material
Examples of Writing Difficulties
Trouble staying within margins or on lines

Writing Strategies

Use a popsicle stick with marks on it to help the student figure out what is good sized space in writing
Use a green marker to make marks on the student’s writing sample to indicate good spaces, and a red marker to make lines for poor spacing. When student understands, let them “grade” his/her own paper
Accommodations
Highlighting margins during writing tasks
