Table 2.

Means and standard deviations of subtypes of tickle-induced USVs and tickle-induced total USVs across the three recording days. Day 1 and Day 4 were recorded prior to the voluntary consumption phase. The post recording day was measured after the drinking phase of the experiment. Fixed frequency (FF), frequency modulated (FM).
