The Effect of Speaking Aloud on Prospective Memory Performance in an Interrupted Situation

摘要

An ability of remembering an intention in an appropriate time is referred to Prospective Memory (PM). PM error occasionally causes fatal errors in various real industries. Therefore, the developing method of preventing PM error is very important. This study was conducted to investigate whether speaking aloud the intention is effective in preventing PM error or not. Speaking aloud is used to prevent forget important plan as RTC in railway industry. Given this fact, to investigate the effect of speaking aloud in preventing PM error is quite matter. In this experiment, the delay-execute paradigm was used, in which some interrupting tasks were involved. Some participates used speaking aloud technique and the other did not. As a result, speaking aloud decreased prospective performance surprisingly. One reason of it could be that participants committed to speaking aloud itself rather than put the PM task in their mind.
