Examples of analysis of behavioral events.

A: An example of a chronogram of the occurrence of behavioral events (a test session of AM-251). In the chronogram, each line represents the time at which each event occurred. M: male; F: female. The first red vertical line indicates the time at which the female was introduced, while the second red vertical line indicates the timing of ejaculation. B: Mean transitional behavioral graphs for all of the test sessions. The colored edges (arrows) indicate significant differences in probability of transitions between the 2 groups (unpaired t-test, p3% are shown. C: Comparison between the 2 groups for durations of head-head contact events during copulatory period, * p
