Sexual Excitement as a Function of Stimulus Novelty Level and Its Repetitions in a Male Pig-Tail Macaque (Macaca Nemestrina) Model (A Medical Hypothesis)

Abstract

Aims. Sexual functioning is generally impaired during depression. This article would like to demonstrate a principle of behavior that can ultimately become a solution of sexual dysfunction by controlling the number of stimulus repetitions then this is an effective way to maintain the novelty of stimulation that can regain the excitement of behavior in terms of response time and duration. Method. An eight years old male pigtail macaque model named John who lives in an individual cage (5x5x5m). The researcher did an audio-visual stimulation as much as 1 time a day at 07.00 am (morning) and did the repetitions for 4 days in a row. Based on video recordings, then response times or arousal times into scratching behavior toward his sexual organs such as penis and anus by his hands and their behavior-duration analysed by using real time player in seconds. Result and conclusion. So far, these result will have implication that if the number of repetitions of the stimulus decreased (thus kept the stimulus novelty level still) then the arousal times into the sexual response (scratching behavior) will be faster, and the duration of the sexual response (scratching behavior) will be longer as the number of repetitions of the stimulus decreases.
