Lec#15: Visual Information Processing Evaluation

what tests are added to a regular exam to make it a visual information processing evaluation? 3

- visual spatial tests

- visual analysis tests

- visual motor tests

what is usually the main complaint of someone with a VIP disorder?

struggling academically- letter reversals, poor reading comprehension, poor handwriting

what are two extra components to ask for VIPE case history?

- developmental history

- academic history

why should you always check pts last exam even if it was a regular exam unrelated to VIPE?

to make sure pt is in best corrected glasses

what are visual spatial skills?

skills used to organize internal and external space

name 3 symptoms of poor visual spatial skills

- delayed motor skills development

- poor coordination and balance

- mixes right and lefts

- frequent number and letter reversals

- reads in different directions

- no dominate hand yet

-difficulty crossing midline

what is the correct order of these skills from easier to harder?

a. directionality

b. laterality

c. bilateral integration

bilateral integration easier

laterality

directionality

what is bilateral integration/ motor planing?

the ability to coordinate both sides of the body

what is laterality?

knowing rights and lefts on the person themselves

what is directionality?

rights and left on someone else or on symbols and characters like letters

name two tests that check bilateral integration

a. chalkboard circles

b. Angeles in the snow

piaget right left tests what two visual spatial skills?

- laterality and directionality

name a test for laterality training?

piaget right left test

what are 3 tests to train directionality?

- piaget right left test

- gardner reversal frequency test

- jordan right left test

how are chalkboard circles performed?

complete 5 revolutions

after you have pt do symetrical circles you do _________ circles.

reciprocal circles- harder

both arms moving clockwise or both arms moving counterclockwise

symmetrical circles

one arm going clockwise and other arm going counterclockwise

what is the goal of chalkboard circles?

work on equalizing both sides of the body

at what age should a pt be able to do symmetrical circles?

age 4

at what age should pt be able to do reciprocal circles?

age 6

grading chart to know

compare age equivalent performance to pts chronological age

very week

greater than or equal to 2 years below age

weak is 1-2 years (including 1 not 2) below age

angels in the snow trains what visual spatial skill?

trains bilateral integration and motor planning

angels in the snow procedure

what is monolateral movement for angels in the snow?

one limb moving at a time

what is homologous movement?

both arms or both legs moving at a time

what is ipsilateral movement?

left arm and left leg

or right arm and right leg

what is contralateral movement?

right and left leg

or left arm and right leg

what is the order of these movement from easier to harder

a. monologous

b. ipsilateral

c. contralateral

d. homologous

easiest: homologous

monolateral

ipsilateral

contralateral

what is very weak performance for angles in the snow?

more than or equal to 2 years below age

what is weak for performance for angles in the snow? same as for chalkboard circles

1-2 equal to 1 but not equal to 2 below the age

what does piaget right left test?

laterality and directionality

pt does the directions or answers questions

how can pt get full score for the letter section?

if they missed one item they do not get credit for that letter section

have to get them all correct

what is very weak and weak score for piaget right lef test?

same

what does Gardners reversal frequency test?

directionality higher level!- only need to know this for exam

Gardner's reversal frequency test- execution test and recognition portions

- these are pts recording test

- for execution test you tell them what letters and numbers to write 5,2,6,3,9,2,7 (numbers you can tell when they are reversed)

trying to see if they can write the letters correctly

recognition test pt circles which is correct

do not have to know grading

KNOW this

what is average percentile score for Gardners reversal frequency test?

32 to 68 percentile

the Jordan left right reversal tests what visual spatial skills?

tests directionality

to determine if the pts visual reversals of letters, numbers and words are normal or abnormal based on their gender and age

jordan level 1

for this sheet pt crosses out any backward letters

jordan level 2

circle the words with backward letters only do if pt is older than or equal to 9

jordan level 3

circle the backward word

what age does pt need to be to do the jordan levels 2 and 3?

= or greater than 9

what is the average for jordan left-right reversal test?

32 to 68th percentile

when should you do visual analysis skills test?

- pt has symptoms of letter and word recognition

- disorganized

- poor visualization and memory difficulties in reading, spelling, math, and comprehension

what is the visual perceptual skills test?

tests visual analysis

- to determine pts visual perceptual strengths and weaknesses based on non-motor visual perceptual testing

Test of Visual Perceptual Skills (TVPS)

follow the instructions in the TVPS booklet for each subtest

tests

- visual discrimination

- visual memory

- visual spatial relationships

- visual form constancy

- visual sequential memory (forget what they read)

- visual figure ground (word serches)

- visual closure

what subtests of the TVPS have a time limit?

there is no time limit for a response on all subtests except visual memory and visual sequential memory (5 seconds presentation)

when is ceiling reached for TVPS test?

when the pt gets 3 out of 4 consecutive items incorrect

what is average percentile for test of visual perceptual skills?

32nd to 68

what are symptoms of poor visual motor skills?

- poor handwriting

- poor spacing

- inability to stay on the line

- excessive erasures

- difficulty completing written work in a timely manner

what is a visual motor test?

Berry development test

Wold sentence copy

how is the beery development test performed?

what do you terminate the beery test?

when the pt has copied 3 consecutive forms incorrectly

what is average percentile score for Berry development test?

32 to 68

Which test of visual motor has a time component?

wold sentence copy

have pt write the sentence as best and fast as they can
