emotional sound and neutral sound
"Neutral voice is a meaningless sound (namely the interjection ah) and the emotional stimuli were the same voice pronouncing the same word with an emotional prosody of happiness or sadness.The stimulus material consisted of positive and negative sound selected from the International Affective Digitalized Sounds (IADS) database.In order to identify experimental stimuli sets that were matched for ratings of arousal and valence between the two valence types,investigators used an algorithm to equate normative valence and arousal ratings for the selection of auditory stimuli."
