An Empirical Study on the Relationship Between Auditory Evoked Potential's P300 waves& IQ Test Scores

The determination of the intelligence quotient (IQ) of individuals with traditional psychometric tests has been a topic of discussion for a long time. However, in recent years neuropsychological studies have focused on the relationship between IQ and brain waves. In particular, many studies have investigated the relationship between Evoked Potential signals and IQ results. In this study, we investigated the relationship between the P300 signal, one of the Auditory Evoked Potential signals, and the IQ test results. Within the scope of the project, the Raven Standard Progressive Matrices (RSPM) test was used to measure participants' IQ levels. In addition, to obtain the P300 signal, the Oddball Auditory Stimulus Model participant was applied by Electroencephalography (EEG) device. Signals are received by the MP150 system and the P300 signal is provided by the MATLAB Signal Processing module. Biostatistical analysis was performed with the data associated.
