This paper describes experiments on extracting EEG components that relate to the impressions of colorpatterns using EEG measurements as well as psychological tests. EEGs of two female subjects were first measured while they gazed at color-pattern stimuli and the α-, β-, and θ-wave components were re-synthesized. The EEG-related parameters were then calculated from all the waveform components. The subjects' impressions of color patterns were quantified in terms of WARM-COOL and HARD-SOFT. Multiple regression analyses were conducted based on the EEG-related parameters and the regression coefficients were determined. These coefficients were used as predicted values of subjects' impressions and compared with the observed psychological quantities. The multiple correlation coefficients for WARM-COOL and HARD-SOFT ranged between 0.80 and 0.84 for the subject in her 20s and between 0.71 and 0.83 for the subject in her 50s. These results showed that some EEG components were highly correlated with psychological quantities.
