How Does This Make Sense?

Some children are assessed using the Christine Roman-Lantzy CVI Range and their visual skills are measured as operating in Phase I. Here is what we know about children in Phase I (Christine Roman-Lantzy)

  • The child has great difficulty locating items in the environment and looking long enough to recognize them.
  • The child lacks visual memory for items in their environment due to this limited looking.
  • The child has a favorite color and will only look at simple one colored items. (Color)
  • The child looks at movement or shiny items but does not seem interested in stable objects. (Movement)
  • There is no or little reaction to visual threat or touch between the eyes. (Visual Reflexive Responses)
  • The child fixates briefly but likes light, ceiling fans and movement. (Light gazing and Movement)
  • The child sees things in the peripheral fields but does not react to items in central vision positions. (Visual Fields)
  • There is visual attention in near space only within 2 feet. (Distance and Complexity)
  • The child rarely looks towards faces (Complexity).
  • The child sees best in uncluttered, quiet places. (Complexity)
  • The child only looks at familiar and favorite toys. (Novelty)
  • The child has a long delay before they turn to look. (Latency)

The child enters school and icons, that very symbolically represent materials, are used.  How does this make sense?

  • The child is not looking at 3 dimensional things in their environment. The icons are 2 dimensional and represent these things. How is the child expected to connect the 2D symbol to an 3D item they can’t look at and can’t recognize??

  • This child is very visually impaired yet pictures are used??
  • The child, if they can locate items, can only tolerate looking at one 3 dimensional item at a time, yet they are presented with a HUGE amount of symbols on a communication system.

  • The child can only look at items that move yet symbols are presented as stable items??
  • The child is constantly told to “look” using central vision, yet it is their peripheral vision which is the most functional.
  • The child is presented with 2 dimensional pictures the represent part of an object (which they can’t recognize in 3 dimensions!).

Teachers of students with visual impairments who understand CVI and how to assess CVI using the CVI Range must work hard to help teams understand this disconnect. Without the vital information gained from the CVI Range, the communication device materials and other 2D learning materials are inaccessible. Would we ever do this to a child with an ocular impairment?? I don’t think so!

Building Literacy Around What Children Care About

We all pick up books based on our preferences for topics.  Why should our children with CVI be any different? Parents have a wealth of information about what their children’s passions. These are the favorite and visually familiar things we should build our literacy materials around for our children.

My student is fascinated by cell phones. I grabbed a Google image of a cell phone (actual size) and chose a fairly complex book. I applied Velcro to the back of the cell phone image and to multiple places on each page.

The book became The Ten Ladybugs and the Cell Phone.

Because my student really likes this item and had a firm visual memory for this item, his success was almost immediate. Once he could locate the cell phone picture, he could hand it to me and play with a cell phone for a minute.

With this success, I can go several places with this skill.  I can increase the complexity of the background and/or decrease the size so the cell phone becomes more symbolic (not the exact real cell phone size).

This makes learning interesting for my student and I can work toward my goals. We are both engaged and happy to work together! We move to increase and expand my student’s literacy interests based on their preferences not mine!

Literacy: Searching for a Salient Feature

My 3 year old student who is non-verbal had no interest in any literacy materials when she arrived in preschool due to ocular and cortical visual impairments.  Her preschool provided rich experience based literacy using adapted books matched to her ocular visual needs and matched to her CVI Range Assessment (Roman-Lantzy 2007). Each book had an accompanying storybox with 3D materials to support each non-complex picture.

I wanted to check visual recognition of one 2D image.  I choose the book Zoom! Zoom! Zoom! I’m Off to the Moon by Dan Yaccarino. It had a series of images of round pictures.  As a salient feature (Roman-Lantzy) I used a shiny, gold, round sticker. I presented this sticker on a white non-complex background. I knew my student loves the Itsy, Bitsy song. With hand under hand support, each time the sticker was presented we would touch the sticker together and I sang part of her favorite song.

With her success with pointing to this one sticker, I applied the sticker in different places on each page of the Zoom! book.

After a week, she was looking at the pages and finding the shiny sticker each time. She would lean closer to reduce the complexity, isolate her index finger, point and look at me and smile. True recognition! With the increasing interest, she really studies all the classroom adapted books and even chooses books during her free time on the mat.
