Abstract

This study was conducted in order to replicate the findings of Earle (1985) in a modern-day setting. Earle (1985) supported that different hemispheres aid in problem solving depending on problem difficulty. These findings were evident by a change in lateral hemispheric inhibition while participants solved “medium” difficulty math problems. Participants were asked to solve multiplication problems in their heads, without the help of a pen, paper, or a calculator. Electroencephalogram (EEG) data was recorded over the Parietal and Temporal lobe during a resting state and while participants solved math problems of “easy”, “intermediate”, and “hard” conditions. Data was recorded from two matching base pairs across the cortex in order to measure changes in the alpha frequency across the two hemispheres. This study was unable to replicate the findings from Earle (1985), but provides information regarding factors to consider when measuring the alpha band with an EEG.
