A text was presented in one of three modalities (auditory, visual, or audiovisual) at fast or slow rate. Modality difference of recall performance was observed only in the fast rate condition. And this modality effect was auditory superiority over visual and audiovisual presentation. Visual inferiority was interpreted in terms of the necessity of translation. It is supposed that the translation from visual input into an acoustic form consumes some time and it leads to processing insufficiency when presentation rate is fast. Visual inferiority is found also in the processing of word-lists, while audiovisual inferiority is peculiar to text processing. From the deterioration of audiovisual performance at fast presentation rate, the visual component of audiovisual presentation also seems to be translated acoustically during text processing.
