Playing Croquet takes a combination of highly developed visual skills

All you have to do is aim a wooden ball with a clumsy wooden mallet to roll through a wicket the size of a clothes hanger. Of course if you bump into a competitor's ball you can advance a bit faster and if you get bumped you may be driven far off course. Suppose you lack the ability to discriminate between left and right on yourself or to project the knowledge of left and right into space? You'll have trouble sending the ball in the correct direction. Suppose you lack the visual perceptual skill of visual memory so that you can't create a mental image of how the ball will respond when you tap it from a certain side? You'll have trouble planning the next moves. Suppose you have delays in the development of visual-motor integration? You'll miss the ball or, if you are bumping another person's ball out of the path you might hit your foot instead. Suppose you have trouble transitioning from a central to a peripheral focus? It will be very difficult for you to judge how to strike the ball in relationship to the wicket yards away. It is needless to conclude that playing the game of croquet requires a combination of highly developed visual skills. So, if you have been playing that game with your children and one of them consistently quits in frustration, you might consider asking a developmental optometrist to do a comprehensive examination of their visual skills. Like optometrists are fond of saying, vision is much more than 20-20 eyesight.

Can't cross the midline - Rake my yard, please!

Children who cannot cross the midline have lots of problems in school. They don't easily form letters like X, V, W, M, N, or Z because these letters require them to draw a line that moves across a diagonal. These kids have trouble finishing worksheets where they have to connect a selection on the left side of the page by drawing a line to its match on the right side even when they can demonstrate mastery of the information orally or in other kinds of written assessments. Regular playground activities like skipping are also very difficult and the most delayed children may not be able to alternate their feet when climbing up or down a flight of stairs. These same children probably do not know their left from their right and may become confused about which side of a word or line of text to read first. By providing lots of gross motor experiences that require a child to cross their physical midline during a program of in-office vision therapy, we can often help them to form the neural pathways that allow them to understand where they are in space. Then we can assist them to apply that knowledge to directions outside of their body. So, it's fall. I spent much of the afternoon raking leaves. It is a perfect chore to give to a child who needs to learn to cross the midline. You hold the rake with both hands and sweep it across your body again and again. Of course, the satisfaction of creating a huge pile of crispy leaves to jump in and hide beneath provides most of the motivation needed. Even very small children can rake if you buy them rakes with shorter handles.

If you suspect that your child may have delays in the development of laterality & directionality, make an appointment for a comprehensive eye exam with a developmental optometrist who incorporated vision therapy into the practice. The doctor may decide to administer a series of normed tests to learn whether your child's visual perceptual skills are developing on schedule.

If you would like to have a set of original activities that assist children to grow in the development of the visual spatial skills of laterality & directionality, consider buying the Yellow Book of the Eye Can Too! Read e-book series by Lesley Barker

Does Your Child Stand With One Leg or Arm Wrapped Around the Other?

Many of the children whom I see for in-office vision therapy have more than one learning-related visual issue that makes it difficult for them to succeed in school. Sometimes a child presents with a severe laterality and directionality delay. Laterality is the ability to tell left and right accurately on yourself. Directionality is the ability to project the knowledge about left and right away from yourself into space. Both are visual spatial skills, i.e. processing skills or visual perceptual skills. We discover the extent of a child's delays using a combination of tests: the Piaget Test of Left/Right Awareness, either the Jordan or the Gardner test of letter reversals, and a dyslexia screener. Children who cannot cross the mid-line or who make frequent reversals when reading or writing letters and numbers often score poorly on these tests, all of which have age/grade level expected normed scores. Then we use a series of activities in therapy to address any laterality and directionality delays. (The Yellow Book in the Eye Can Too! Read series provides parents and teachers with similar activities and information about how to understand a child's behavior when doing them.) I have recently noticed that many of the children with the most severely delayed laterality and directionality skills stand or sit with one leg wrapped around the other. They often twist their bodies when standing, and seem to be holding themselves together with the right hand grabbing their left side and the left hand grabbing their right side. I think that this postural habit exacerbates the problem by making it difficult for the child to know which body parts belong to the right side and which to the left. I have begun to coach parents to discourage their children from using these positions as another way to address the child's visual spatial problems which they sometimes express as being "confusing." I'd love to know whether others see the same correlations. Feel free to add your comments. Thanks.

Does your student make frequent reversals when reading or writing? Here's help!

If your student makes frequent reversals when reading or writing or gets confused about left and right, the second book, The Yellow Book, in my three book series: Eye Can Too! Read ...Better, Faster, Without Making Reversals or Getting Confused may help. These behaviors are often due to a delay in a student's development of the visual spatial skills of laterality and directionality. Sometimes students who make frequent reversals when reading or writing are labeled dyslexic even though there is no consensus among the various disciplines on a definition for dyslexia. However, many of these students who receive vision therapy designed to address the visual spatial developmental issues overcome them. They often make significant gains in their academic performance as a result. The Yellow Book contains a series of activities like the ones we use in the vision therapy context which are designed to help students improve both of these visual spatial skills. Created with home-school families in mind, each activity identifies the visual skills used, the academic objectives and appropriate grade or ability level, a list of materials needed, clear instructions, and a set of observation guidelines to help you to understand what your student's performance may indicate. The book is available at http://www.home-school-inc.com/store/p-15-item-000014.aspx as a pdf download or as a printed spiral bound text. The Purple Book (the first in the series) is also available online at Home School Inc- it gives similar activities designed to help students improve the eye movement skills that must be in place for a student to be able to read efficiently without skipping words, lines, or losing their place. In a few weeks, the third book in the series, The Green Book, will also be available. That book provides academic activities designed to improve a student's visual perceptual skills. Each book contains graded activities for Pre-K through 8th graders. While they are all written for a home school audience, classroom teachers will find the activities easy to adapt for their class either as whole group or learning center activities.

K-12 Learning Center Activity - BDPQ Jumps

Learning to tell left from right on yourself is the visual spatial skill of laterality. Extending it into space is the visual spatial skill of directionality. Both are developmental skills that impact a student's ability to learn to read, write, and do gross motor activities. Here is an activity that is similar to one we use in the vision therapy context to assist patients to develop laterality & directionality. It is meant to be used as a K-2 Learning Center Activity.

Title: BDPQ Jumps

Learning-Related Visual Skills: This activity uses the visual spatial skills of laterality and directionality as well as saccadic eye movements, the small hops the eyes must make to go accurately from the end of one word or line of text to the next.

Academic Objective: This activity gives students practice reading and naming lower case b, d, p, and q.

Preparation: Create a chart with 5 rows and 5 columns. Do not put the gridlines in. Randomly arrange b, d, p, and q so that there are five letters on each line. A text size of 42 will be readable at 5-7 feet for most students. Post the chart on a bulletin board. On the floor in front of the bulletin board, use colored masking tape to create a pair of intersecting perpendicular lines 4 feet x 4 feet.

Directions: Show the students that the vertical tape line is analogous to the stick of each letter while the space left by the intersection is analogous to the letter's circle. So, the lower right space is B; the upper right space is P; the lower left space is D; and the upper left space is Q. Students are to work as pairs to jump into the space that matches the letter on the chart which they must read from left to right and from top to bottom as usual. The jumper must also say the name of the letter correctly. Partners observe each other while keeping track of where the jumper is on the chart and watching for mistakes. If a jumper makes 3 mistakes before finishing the entire chart, the roles change. The observer becomes the jumper. How many turns does it take for each partner to jump through the chart making fewer than 3 mistakes? Set a time limit of 10 minutes for each partnership to remain at this learning station.

Why Is Left/Right Awareness Important to Reading?

Since we read from left to right and from the top of the page down, beginning readers who do not know their left and right may experience some confusion. We call the ability to tell left and right on ourself the visual spatial skill of laterality. Laterality is usually developed, according to Piaget's observations, by the time a child is 7 years old. Projecting that knowledge away from ourself into space is the visual spatial skill of directionality. This involves layers of developmental understanding that evolve in most children by the time they are 11.

Children who have delays in the skills of laterality and directionality mix up their left and right. They often have poor bilateral integration. In other words, they tend not to use both hands or feet efficiently to do tasks like cutting, eating, and alternating their feet going up and down stairs. They probably also have difficulty crossing the midline. By this I mean the physical midline, the ocular midline, and the midline on a page of text or on a worksheet.

So, these children will become frustrated by assignments that involve drawing lines to match information arranged in a column on the left side of the worksheet with additional information arranged in a column on the right side of the worksheet. They may know the correct answer but be unable to connect the lines. They may exhibit poor manuscript handwriting- especially when forming letters and numbers which cross the midline like x, y, M, N, s, v, and w.

Sometimes these children make frequent reversals when reading and writing and the children who are the most developmentally delayed in laterality and directionality may mirror write. They are often labeled dyslexic, a condition that has many competing definitions and involves both visual and auditory perception and processing.

It is possible to build a child's developmental skills of laterality and directionality and to increase their left/right awareness. In fact, occupational therapists and vision therapists spend a lot of time in therapy doing just that for our patients. There are normed tests available to measure a student's development in laterality and directionality that are incorporated in the developmental assessment of a child's visual perceptual skills given by developmental optometrists and by educational psychologists.

I believe that one easy to achieve educational goal should be to provide activities in laterality and directionality for every primary student before they fall behind in reading and writing. This can be done via learning center activities in the classroom. To that end, the second book, the "Yellow Book", in the Eye Can Too! Read series, published by Home School Incorporated, (available in the next few weeks on their website) provides an assortment of activities that home-school families and classroom teachers can use. There are clear directions followed by questions to inform your observation of your student as they do the activities.

This blog is intended to give information for parents and teachers about learning-related visual skills. I encourage each reader to become a follower of this blog and also to become a fan of the Eye Can Too! Read FaceBook page. Please use the wall on the FaceBook page to ask your questions about vision and learning. That will help me to select topics for this blog. Thanks.
