Many individuals experience difficulties in certain cognitive tasks, yet excel at others. The QEEG technology is able to provide some understanding of why that occurs. In addition, as we now have an understanding of the relationship between the QEEG variables and cognitive effectiveness, it becomes a relatively easy matter to improve the cognitive abilities of normal individuals.
The figure below documents the problem of different levels of abilities in the same individual. The subject presented below is an example of an individual who has superb auditory memory abilities yet has below average reading memory scores. The subject reported a long history of reading problems which were never formally assessed in the school environment. The difference between her auditory and reading memory scores was about 4.5 standard deviations, a considerable difference. The top figure shows her coherence alpha relationships under the paragraph recall task, while the bottom row shows the problems in the coherence beta relationships during the reading task.
Coherence alpha relationships during auditory memory task
Coherence Beta1 (13-32 Hertz) relationships during reading
The figure above presents the results of a normal individual on the auditory paragraph recall task.
In the head figures where there is one location with no circle or a black circle, the location represents the origin of a "flashlight" which "sends" out its beam to the other locations. When the beam arrives at a particular location a coherence value is calculated. The colors of the circle indicated the standard deviation (SD) difference from the normative reference group. The white color indicates that the subject was within the range between +.50 and -.50 standard deviations. The light blue indicates the subject was between -.50 and -1.50 SD. The dark blue indicates the subject's value was below -1.50 SD. Light orange indicates the subject was between +.50 SD and +1.50 SD while the dark orange indicates a value above +1.50 SD. The number in the circle is the SD value for the top two sets of head figures. The bottom set presents only the color or SD codes for the values obtained.
