Abstract

Six naïve subjects were presented a weighted 24-step morph sequence of themselves and Marilyn Monroe under three conditions: normal, low-band pass filtered, and high-band pass filtered. Five subjects show a strong preference for perceiving the low-band pass filtered stimuli as representative of “themselves” and the high-band pass filtered stimuli as representative of “Marilyn.” The sixth subject was very strongly reversed, and data, when analyzed in terms of differences in PSE of the two conditions showed an outlier effect with respect to the other five subjects. Data excluding the outlier was shown to be significant with respect to PSEs (p<0.003). On average, the normal condition PSE fell right at the midpoint between high and low-band pass filtered conditions. Data is consistent with the hypothesis that self-recognition requires more low-band than high-band spatial information, and is likely lateralized to the right hemisphere because of this. Data also provides preliminary support for the more significant hypothesis that familiarity may fall along a continuum where familiar objects always require more low-band spatial frequency information or less high-band spatial frequency information than unfamiliar objects.
