Amplifying Sound Intensity of Key Words in Discourse Promotes Memory in Female College Students.

Purpose: The aim of this study was to determine whether amplification of key words in discourse helped to memorize the words.

Method: We tested the effect of 135 participants' memory for key words in the discourse after intensity amplification (0, 5, 7, 9, and 11 dB), and we also tested physiological indicators to measure attention levels in another 30 participants. Adobe Audition was used to modulate the intensity of key words, whereas E-prime technology was used to present speech stimuli and test the accuracy of the memory of the participants.
