[A major factor of the decline in partial report performance with temporal delay].
The purpose is to clarify what is the primary cause of decline in partial report performance due to cue delay over a given time period. Four subjects participated in the partial report task, and their performances were compared by using two types of stimuli: mixed-character matrix (alphabet, katakana, and kanji) and single-character matrix (one of the three characters), under the tachistoscopic presentation. Both matrices are arranged in three rows by four columns. The result was that the report performance declined almost equally as the cue delay increased under the mixed- and single-character matrix stimuli, even though the location confusion would not influence on the report in the mixed-character condition. Consequently, we may conclude that the decline in partial report performance was caused by the decay of identity information rather than that of location information. Further, the error trends revealed that the earlier researches using single kind of character stimulus (almost exclusively alphabet) overestimated the location error.
