Checklist for Identifying Visual Perception Difficulties in a Student's
Schoolwork


By: Melanie Lambert, Occupational Therapist
Visual Learning for Life, Ltd., London, England, UK

Visual perception is the interpretation of visual stimuli; i.e. the brains ability to take what the eyes see and give meaning to it. Visual perceptual difficulties can severely hamper a child's ability to achieve at school considering that 80% of what students are expected to learn in school comes through visual opportunities.

In an effort to equip parents and teachers with with the knowledge of how to identify difficulties with visual perception, I compiled a list of some of the informal observations one would make in a child's schoolwork with regards to each visual perceptual component. I have found this checklist to provide valuable insight into a child's functioning in the classroom situation. I hope this checklist will prove a helpful tool in your practice too!

Form Constancy Perception: The ability to identify, name and sort the same objects, shapes and symbols despite differences in their size, shading, texture and/or position. Form Constancy problems reflected in schoolwork:
  • Difficulty recognizing a shape he/she seemingly knows well when presented in a different way to what was originally taught and learnt e.g. different material or colour
  • Difficulty distinguishing between similar forms e.g. circle/oval; square/rectangle
  • Difficulty recognizing that a shape in a 3D form e.g. block on a table is still the same shape in a 2D form e.g. square drawn on the board
  • Difficulty projecting the idea of a shape onto something familiar to him/her e.g. a door is rectangular
  • Fails to recognize letters, words or numbers presented in a different writing style
  • Difficulty recognizing a word if presented in higher case as opposed to lower case
  • Difficulty recognizing that a maths sum written vertically is the same as when written horizontally
  • Difficulty referring to something in the textbook that has been written on the blackboard
  • Limited sight word vocabulary
  • Confused with similar looking words e.g. clock, clear, click, cling, clown
  • Difficulty recognizing words in vertical forms e.g. crosswords
  • Confuses similar letter symbols e.g. o/a; n/m; v/w; r/n


Visual Discrimination: The ability to see differences and similarities in shapes, patterns and objects. Visual discrimination problems reflected in schoolwork
  • Difficulty sorting our geometric shapes
  • Difficulty identifying identical letters or words and may confuse letters and words that are similar
  • Confusion between b/d, u/v, m/n, r/n, n/h, p/q/g
  • Difficulty classifying things (struggles to see similarities and differences)
  • Misreads words, substitutes or omits words
  • Difficulty discriminating between symbols e.g. > <, + x,, รท
  • Difficulty distinguishing money by size of coins
  • Difficulty differentiating between acute and obtuse angles
  • Symbols of elements confused in science


Figure Ground Perception: The ability to distinguish an object/word/letter/number from the background surrounding it and maintain it in the foreground for as long as is necessary. It requires the eyes to focus on and identify specific objects/words/letters/numbers between others. Figure-ground problems reflected in schoolwork:
  • Difficulty keeping his/her place in reading or number work
  • Looses his/her place when copying from the blackboard or textbook
  • Skips sections when working through an exercise
  • Unable to find objects that are sometimes right under his/her nose
  • Difficulty looking up words in a dictionary or places on a map

  • Unable to attend to individual words on an overcrowded page
  • Difficulty understanding detailed pictures or diagrams
  • Does not see (+) amongst (-) sums when presented on the same page (mixed computations)
  • Confuses the number of the sum with the sum e.g. 3. 4+3=
  • Distractible and disorganized (Attention jumps to any activity)


Position in Space Perception: The ability to understand and perceive the position of an object in relation to one's own body. Position in space problems reflected in schoolwork:
  • Poor grasp of spatial terms e.g. in, out, over, above, below, through, under, between etc. (Difficulty executing instructions with these terms correctly)
  • Difficulty organizing or changing his/her own body position according to instruction
  • Difficulty organizing himself/herself in relation to other objects according to instruction
  • Puts things away upside down or wrong way round without noticing
  • Difficulty setting up games correctly e.g. board facing the right way, all cards facing up
  • Reverses numbers and figures when writing e.g. 'b' and 'd', ' and 's', ' and '3'
  • Confuses 'b', 'd', 'p', 'q', 'g' etc. in reading and spelling
  • Reads from right to left e.g. mad for dam, tap for pat
  • Poor judgement of spacing in writing
  • Appears to ignore punctuation in reading and writing
  • Disorganised on paper (Confuses top/bottom and left/right of page)
  • Poor ability to organise his/her desk
  • Reverses and rotates geometrical figures in maths
  • Found to have wood or material wrong way round in needlework and woodwork subjects
  • Confused direction in sports games and has difficulty positioning himself/herself
  • Difficulty in map work (Confuses north, south, east, west)

Spatial Relationships Perception: The ability to perceive the position of two or more objects in relation to oneself and to each other. It includes the ability to identify left and right on one's own body and apply it to objects. The ability to understand direction as well as reversals. Spatial relation problems reflected in schoolwork:
  • Difficulty organizing objects in relation to one another e.g. "Put the book on top of the table" or "What is on the left of the gate outside?"
  • Incorrect sequencing of letters and numbers e.g. siwm = swim, 240 = 204
  • Difficulty in telling time or has poor sense of time
  • Reads and writes 'b' for 'd', 'p' for 'q', 'm' for 'w' etc.
  • Transposes letters within a word e.g. reads left for felt, spilt for split (Relative position of letters not perceived correctly)
  • Confused with the order of vowels in words e.g. oa/ao, ou/uo
  • Writes letters of the same word on incorrect lines e.g. p en
  • Gets word order wrong, adds or omits words in expressive writing exercises (Difficulty organizing thoughts into sentences)
  • Has difficulty lining up a vertical sums correctly
  • Difficulty with graph related activities
  • Difficulty giving directions or following a map or diagram
  • Difficulty planning and organising use of space on paper
  • Poor drawing skills (Parts may be scattered or have incorrect orientation)
  • Difficulty copying 2D patterns and learning how to print letters/numerals
  • Difficulty constructing a 3D model from a 2D plan


Visual Closure Perception: The ability to identify an object, shape or symbol from a visually incomplete or disorganized presentation. It includes the ability to complete incomplete parts of a picture/figure.

Visual Analysis and Synthesis: The ability to see that certain parts make a whole. The understanding of the relationship between parts of a figure/word/sentence and the whole figure/word/sentence. Visual closure and visual synthesis and analysis problems reflected in schoolwork:

  • Difficulty completing a drawing or letter if given only a part
  • Only reads half a story during a comprehension
  • Do not read full examination question
  • Difficulty envisaging a complete article when doing construction activities


Visual Memory: The ability to recall or reproduce a number/letter/object/figure that has previously been seen for a short period of time i.e. to remember what has been seen.

  • Slow motor speed in writing
  • Performs poorly at sport
  • Confuses left and right or other directional concepts
  • Difficulty reproducing a figure, letter or numeral from the blackboard or a book

This Month's Featured Product: Visual Perceptual Skills Builder

Special Thanks to Melanie Lambert and Summerdale Educational Services for providing an article for this issue's Therapy Corner.

Ms. Lambert is the designer of the Visual Perceptual Skills Builder CD Program. She ran a pediatric private practice based at a remedial school in South Africa for a number of years. During this time she was involved in assessing and treating children with learning difficulties and developmental delays. She was also involved in educating teaching staff with regards to visual perceptual problems and motor delays and providing teaching staff with strategies to address these problems in the classroom situation.

The practice formed a consultation base for a fairly large geographical area with a limited therapy infrastructure. She received a number of referrals from children who had to travel from further afield and were unable to attend regular weekly therapy sessions to address their particular learning needs. It was during this time that the idea for the Visual Perceptual Skills Builder was hatched.

Melanie moved to the UK in April 2005 and has been working in a pediatric private practice in London since then.
