Abstract: Four experiments tested a proposed extension of Double Filtering by Frequency theory by examining whether the left and right hemispheres of the human brain are differentially sensitive to high and low electromagnetic frequencies, respectively, and whether this effect is primarily based on relative or absolute frequency levels. Experiments 1 and 2 provided initial support by replicating a known hemispheric effect using different background colors. Experiments 3 and 4 provided converging evidence by varying visual field presentation and measuring participant's reaction times. These findings indicate that the right hemisphere is relatively more sensitive to low frequency colors, whereas the left hemisphere is more sensitive to high frequency ones. The findings also suggest that this difference is primarily based on absolute frequency levels. Implications and possible applications are discussed.
