Influence which the sound as a noise has on maintenance of phoneme information

Abstract

This research is investigated from the viewpoint of cross-language processing about the influence which the noise generated by reading aloud has to the maintenance results of phoneme information. If a sentence is read aloud simultaneously when holding phoneme information, the quantity of the phoneme information which can be held and set will decrease. This phenomenon can check the rehearsal of the phoneme information which the noise produced by reading a sentence aloud holds, and it is also possible that maintenance results fall as a result. Then, in this research, the cognitive psychological experiment was conducted using the dual-task method of reading aloud of a sentence, and memory of a word (phoneme information). Two conditions of a native language and a foreign language were set up as a noise generated by reading aloud, and it examined to what noise memory of phoneme information would decline from the point of the individual difference of phonological short-term memory (phonological STM) capacity. Consequently, the more phonological STM capacity was large, the more it was suggested that the stoutness of the phoneme memory to a similar noise increases.
