WAIS-IV Report

d. Working Memory Index (WMI)

John’s ability related to concentration, attention and exert mental control was assessed in the above average range and above approximately 87% of his peers (WMI=117; 95% confidence interval = 109-123). The Working Memory Index measures concentration and attention, short term memory functions, sequencing, facility with numbers and mental flexibility. John performed comparable on the two subtests contributing to the WMI, suggesting similar develop in both abilities. By calculating the difference between the highest and lowest subtest scaled scores for the WMI it was determined that these was no abnormal scatter (Scaled difference = 0).

John has a strong performance among the Digit Span and Arithmetic subtests. The digit span subtests required John to recall and repeat auditory information in the proper sequences, both forward and backwards. A more complex sequence is required with the Digit Span Sequencing as it not only requires recall of digits, but manipulation and rearrangement of information in the correct sequence (Digit Span scaled score = 13). John scored higher in his Digits Backwards than on his Digits Forwards that suggests excellent numerical abilities. This is a rare event and only occur in 0.9% of Adult WAIS-III profiles (Digit Forwards scaled score = 10 and Digit Backwards scaled score=14). The Arithmetic subtest measures John’s computational skills, auditory short-term memory, numerical reasoning and speed, concentration, distractibility, acquired knowledge and logical reasoning. This subtests is a good indicator of John’s alertness, capacity for concentration, freedom from distractibility, auditory short-term memory and suggested John possesses the ability to focus on facts during emo...

...al comprehension abilities that allows him to communicate ideas and concepts verbally and enable him to integrate his social skills effectively in any situation. John is able to monitor his own progress and to ensure that he completes projects on time despite interruptions.

John can improve and maintain his processing speed abilities by finding educational applications to improve brain processing speed and use it on a regular basis. John should improve his perceptual reasoning skills by talking himself through the process of spatial problem-solving and to concentrate on solving the problem at hand and not to determine why the problem exists. He can further benefit by playing puzzle, pattern and “spot the difference” games on the computer during his normal breaks. He can also use these applications to involve his children and introduce it as a family fun activity.
