TABLE 5.

Mean pleasantness ratings for the most frequently misidentified sounds in Experiment 1 as a function of how they are identified.

Sound name	Identification accuracy	Rating when perceived as unpleasant or misophonic	Identification accuracy	Rating when perceived as neutral or pleasant	Rating difference
Tool scraping	Incorrect	–0.2	Correct	–0.4	–0.2
Cereal stirring	Incorrect	–1.4	Correct	0.5	1.9
Chewing food	Correct	–0.9	Incorrect	–0.1	0.8
Fork scraping plate	Correct	–2.4	Incorrect	0.5	2.9
Average		−1.2		0.1

For each sound stimulus, the sound token name is presented in the first column. The Identification accuracy column illustrates whether participants identified the sound correctly, i.e., with a label that fit into the same a priori emotional category (correct), or whether they misidentified the sound with a label that fit into a different a priori emotional category (incorrect). For the Correct entries, the mean pleasantness rating is taken across those participants who correctly identified the sound (less than 39 but always greater than 4, see Table 4); for the Incorrect entries, the mean pleasantness rating is taken across the 4 or more participants who made similar mistakes on the same sound. The bottom of the table shows the average mean pleasantness for when a sound is perceived as unpleasant or misophonic and when it is perceived as neutral or pleasant. The green and purple color code for these averages connects with the one seen in Supplementary Tables S4, S6. Here, a green box denotes when any category of sound is perceived as a sound in a neutral valence group. A purple box denotes when any category of sound is perceived as a sound in a negative valence group (either misophonic or unpleasant category). These average values can also be seen in the regular blue lines in Figure 2.
