Complex cognitive functions such as cognition through thinking, apprehension, learning, and computation are required while attempting to solve logical thinking/ reasoning problems. Human logical thinking and decision making are studied by numerous academic fields in an effort to decipher their underlying neuro-functional/ anatomical mechanisms. The great temporal resolution of electroencephalography (EEG) makes it an infamous brain mapping tool in contemporary neuro-engineering research to investigate the underlying brain activation dynamics during the execution of a certain task. In this proposed research paradigm, an attempt was made to investigate the characteristics of the underlying brain activation power dynamics associated with correct and incorrect responses to a questionnaire based on logical problems for the corresponding EEG frequency bands. Using the Welch’s Power Spectral Density method, it is observed that the band power strength of the Beta band is impressive for correct answers, whereas EEG responses indicating incorrect answers exhibit high Gamma band power. High band power intensity in the Beta frequency band for correct responses correlates with the participant’s aptitude for solving logical problems and indicates a conscious, vigilant mental state. As a result of a greater concentration span and underpinning cognitive exercises in the brain, it is anticipated that incorrect answers will result in increased Gamma frequency band activation.
