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, p<0.05); blue and red arrows indicate that probability was higher in the vehicle AM-251 groups, respectively. Black arrows indicate that probability was not significantly different between the 2 groups. The thickness of the edge (arrow) is proportional to the corresponding probability of transition. Only the edges with a probability of transition >3% are shown. C: Comparison between the 2 groups for durations of head-head contact events during copulatory period, * p<0.05. D: Comparison between the 2 groups for frequency of transition from stop without contact to head-head contact (left), and the transition from follow to head-head contact (right),*p<0.05.
