Effects of different play experience on the number of 50-kHz and 22-kHz USVs per tickling session. a 50-kHz USVs. The violin plot shows the distribution of number of 50-kHz USVs per tickling session. Bars show the group median and the 1st and the 3rd quartile. Upper and lower whiskers extend from the bars to the largest/smallest value no further than 1.5 times of the distance between the first and third quartiles. X-axis shows three treatment groups and y-axis shows the total number of 50-kHZ USVs per session. b 22-kHz USVs. Each dot represents one rat from one session. X-axis shows three treatment groups and y-axis shows the total number of 22-kHz USVs per session. Three extreme values above 100 on y-axis are labelled and displayed out of the scale
