Team spirit of Motivation within the circumstances of motor styles no longer grading imperceptibly into each other yet separated through unexpected cessations of yes routine and both surprising emergences of others, as are tail beating and biting, this can be a challenge of even if excitation adjustments in caliber or purely in volume. To the naive observer, it can appear noticeable that the latter have been actual, yet this intuitive assumption needs to be supported via rational confirma­ tion. the 1st verification includes absolutely the predictability of the next degree of intensity—once the previous degree has been passed through. while Seitz tested cichlid struggling with to our scholars in Konigsberg, he observed the activities of the fish with a operating com­ mentary, in a lot a similar means a radio announcer could do for a boxing fit. yet simply as he used to be wont to do while displaying one in every of his personal beau­ tiful movies, he made allowance for the response occasions of his listeners via waiting for, by means of a couple of seconds, what the fish have been going to do. frequently he 114 I. fastened Motor development had already pointed out the tail beat, and needed to cease a moment or so, wait­ ing for the fish to do what he had simply stated they might do. It was once comment­ capable how few scholars spotted this and have been stunned through his prescience. as well as the opportunity of reliably predicting the events cor­ concerning the subsequent, greater level of depth by way of staring at a precedent step, one other argument for assuming one qualitatively con­ stant excitation is the widespread incidence of combos, and of tremendous fast switches from one trend to the following and again back. additionally, gen­ uine goal hobbies linked to the subsequent greater degree of inten­ sity could be saw whereas decrease depth styles are nonetheless being in line with­ shaped. In a Haplochromis male, the 1st tricks of turning in the direction of an adversary whereas nonetheless within the part of broadside show are only as a lot purpose routine as are the 1st beginnings of preflight pursuits in a quiescent heron. a 3rd argument for assuming that it's a qualitatively exact exci­ tation activating the graded scale of other intensities lies within the com­ plete loss of "inertia" proven via the transitions from one motor development to the subsequent. As might be mentioned in O ne/V /4, an animal wishes a consid­ erable period of time to alter its "mood" (Stimmung, Heinroth), that's to claim, to modify from one method of instinctive habit to a different. the necessary interval is that for much longer the extra advanced and inte­ grated the 2 platforms are and, additionally, the superior the inhibitive influ­ ence they exert on another. there's one exception to this rule: as could be defined in Tw o/V III/2, the so-called greatest determining approach can influence lightning-like switches among competing motivations, for example, among assault and flight. another way, a brief transition from one motor trend to a different argues for the idea that one moti­ vation is activating either. A fourth argument for the harmony of excitation is the truth that one and an identical freeing mechanism, in different phrases, an identical stimulus con­ figuration, elicits all the motor styles correlated to varied intens­ ities.
