1996 Study

These studies were done in a clinical setting with children or adults that had learning problems. Tests were given 10 weeks apart.

Auditory Processing

PS = Processing Speed; SA = Selective Attention; RF = (letter) Reversal Frequency; FIXV= Calling out a vertical column of numbers (processing speed); FIXH = Calling out a horizontal row of numbers (processing speed); TRCK = Tracking a line with other lines present (processing speed and selective attention);WJ3 = Visual matching from the Woodcock-Johnson Cognitive Test Battery (processing speed); RFRQ = Reversal frequency test from Gardner
The following tests are from SOI-LA (Structure of Intellect - Learning Abilities Test): VISZ = The ability to picture a complete system of ideas in the mind - critical for understanding long sentences, directions, and instructions; CFU = Test of visual closure - to recognize familiar figures that have been partially obscured; CFS = Ability to comprehend arrangements and positions of visual objects in space; CFT = Ability to recognize a figure when it has been rotated into a new orientation; EFU = The ability to evaluate and discriminate among complex figures; VMEM = Visual memory; STM = Short term memory; AMEM = auditory memory; VMTR = Eye-hand speed and coordination; NSI = Logic and form reasoning; CMR = Ability to see relations between ideas or meaning of words; CMU = Test of vocabulary and verbal concepts; ESC = Ability to classify symbolic information.
TONI-2 = Test of Nonverbal Intelligence (measures the ability to reason without words and to solve spatially defined problems. An IQ score of 100 is considered average.)
