Number of bats reacting with body turns to stimuli in the playback experiments. Responses (no. of bats reacting) determined in the video analysis for reciprocal aggression (A, experiment “weak to strong”; B, experiment “strong to weak”) and response (C, experiment “weak to strong”; D, experiment “strong to weak”) call experiments, and the control experiment with a strong control stimulus of low frequency (E, experiment “strong to low frequency”) are given to the first habituation stimulus (1^st hab), the second to last habituation stimulus (2^nd lst hab), the last habituation stimulus (lst hab), the test stimulus (test/ control, highlighted in grey) and re-habituation stimulus (rehab). Across the stimuli marked by the horizontal bar, the numbers of bats reacting were compared to check for a classification according to affect intensity. An asterisk indicates that the number of bats reacting to the respective stimulus differed significantly compared to the number of bats reacting to the other three stimuli according to a Cochran’s Q test, followed by its subset comparison supplement [45], in a given experiment; “n.s.” above the bar indicates that the number of bats reacting to the four stimuli did not differ significantly according to Cochran’s Q test.
