CLASSICAL ETHOLOGICAL THEORY: KONRAD LORENZ, NIKO TINBERGEN MUCH OF ANIMAL BEHAVIOR IS INSTINCTIVE INSTINCTIVE BEHAVIOR = : 1.)

When the fighting fish sees the red belly of another male during breeding season while he is defending his territory, he will attack in a stereotyped manner. There are a great many such examples, ranging from mating rituals to parenting behaviors. INNATE RELEASING MECHANISM (IRM): AN IRM IS A MECHANISM THAT TRIGGERS AN INNATE SEQUENCE OR PATTERN OF BEHAVIOR AS A RESULT OF PERCEIVING A STIMULUS; E.G., RED BELLY OF ANOTHER MALE TRIGGERS AGGRESSION IN FIGHTING FISH. IF IRM PRESENT, THEN FAP WILL BE EMITTED. THE IRM IS A PHYSIOLOGICAL MECHANISM IN THE FISH. IT RESPONDS TO A CERTAIN STIMULUS, SUCH AS THE RED BELLY OF ANOTHER MALE, AND TRIGGERS A PARTICULAR BEHAVIORAL SEQUENCE, IN THIS CASE, AGGRESSION....
