Recent studies reported values of power spectrums inside the spatial frequency regarding images of handwritten characters. However, no psychological experiments have investigated the spatial frequency band needed for perceiving characters’ pictorial features. This study investigated the width of the spatial frequency band used for distinguishing features of writer or font style from handwritten characters’ pictorial features. With stimuli for low and high spatial frequencies, participants (N = 9) were asked to discriminate, for each picture, the writer or font style and then name it. We measured thresholds by applying the method of limits. Results suggested that, in the pictorial features of handwritten characters, features of writers’ strokes are expressed by a wider spatial frequency band than features of font style. Our findings indicate that writers’ individuality could be expressed in various methods, and thus handwritten characters’ nonverbal features might help one execute more various design presentations.
