THE RELATIONSHIP BETWEEN PROJECTED IQ FROM QEEG AND NEUROCOGNITIVE ABILITY

Abstract

Intelligence Quotient (IQ) scores are used as a measure to predict intelligence through a series of tests. Studies show that various methods can be applied in order to acquire ones IQ score. Of key interest, new technology such as the use of an electroencephalograph (EEG) can be used. An EEG is a computerized recording of the electrical activities of the brain, and with one reading it is able to give an assessment of the brain as well as the IQ scores. This is important because it could mean that instead of having people undergo a battery of tests in order to acquire an IQ score, one intervention can be utilized – the EEG. Currently, there is minimal discourse regarding the relationship between an EEG’s projected IQ scores and neurocognitive functionality. Potential for neurocognitive ability can be measured through scores of tests, which are used to determine IQ and these are usually administered by a registered professional. The aim of this paper is to bring to light the ability of the EEG to measure IQ as well as to highlight the benefits of using EEG measurements for IQ rather than the conventional ways of testing. This can be done by collecting QEEG measurements of projected IQ which has three categories namely, global, verbal and nonverbal intelligence and then correlate these scores with scores attained from conventional tests with similar categories. Research that has been previously done confirms this paper’s preliminary hypothesis in finding significant correlations between EEG and intelligence, thus demonstrating predictive ability of EEG to measure neurocognitive performance.
