Previous studies have shown association between emotions and memory and how in certain condition emotion enhances memory. However, there has been no study done to test the performance of memory when a neutral content being portrayed in different emotional intonations. Thus this study is on primary memory. A randomized controlled trial done on medical students from May 2018 to June 2018. Sample size is 30 in each intervention group consisting of positive emotion, negative emotion and neutral group sampled purposively and randomized into three. Participants were given an audio with emotional intonation; positive emotion, negative emotion and neutral respectively according to groups and tested on their primary memory with Multiple Choice Questions (MCQs) and structured questions. Group with high mean score of total correct percentage is defined to have better primary memory. Dropout rate of this study is 0%. Neutral group scored the highest compared to positive and negative emotion groups (p-value 0.176). Confidence level is also highest in neutral group compared to positive and negative emotion groups (p-value 0.152). Mean score of the total correct mark percentage for neutral group is 54.7+/- 17.6, followed by positive and neutral, 54.0 +/- 15.1 and 47.7 +/- 14.8 respectively. Median of confidence level of neutral group is 3.0 (2.0, 3.0), followed by 2.0 (1.0, 3.0) for both positive and negative emotion groups. In this study, emotions do not directly associated with memory enhancement compared to previous studies. However, it is notable that the effect of neutral content portrayed in emotional intonation may have been different than emotional content itself.
