Knocking on a yellow door: interactions among knocking sounds, colours, and emotions.

<p>Everyday&nbsp;sounds&nbsp;play&nbsp;a particular role in some media, such as video games and movies, where they are associated with visual contents.&nbsp;</p> <p>In this context, we present the audiovisual stimuli used for&nbsp;a&nbsp;study (n=60) done to&nbsp;investigate&nbsp;the hypothesis that the association between knocking sounds and emotions changes if the knocking sound is performed on a door of a different colour.&nbsp;This study draws inspiration from a previous experiment on knocking sound by&nbsp;Pauletto&nbsp;and co-workers.<br> &nbsp;</p> <p>The audio-visual materials consist of&nbsp;5 professionally performed emotional audios taken from Barahona-R&igrave;os &amp; Pauletto (2020) synchronised with a video of a hand knocking on a door of 5 different colours, for a total of&nbsp;25 videos.</p>
