And there is some optimum emotional arousal (optimum motivation), in which the activity most effectively. Look at the results of these experiments with a slightly different point of view: imagine a situation where a certain level of emotional arousal is not defined experimentally, and, conversely, acting by a single stimulus of varying strengths at different times, to watch what will be an emotional reaction, depending on the magnitude of the effect . Dominant motivation in this case assume a constant value. If efficiency is, though indirectly, but the rate of positive emotions, and inefficiency - indicator of negative emotions, the results of experiments are quite consistent with the above examples. As examples: the taste, of natural causes, interactions with people, feeling attractive, physical and occupational activity, and others, shows that positive emotions often cause only effects (common) stimuli of medium strength. The effect of exercise, the fact that the practical application of annoying, "diversionary" means, as well as use in practical psychology of the phenomenon of "catharsis" - allow us to estimate the role and influence have experienced emotional reactions to the strength and sign of the actual emotional response. The observed pattern of strong, medium and weak variants of exposure occurs only if a sufficient frequency (frequency) of all options for exposure, but usually at the highest frequency of the impacts of moderate strength, as evoke positive emotions. A rare stimuli (including extreme options for its effect), regardless of their biological significance (power) is always perceived as a new organism, and response to them will be either the orienting reflex, or avoidance. In these definitions of "stimulus" may be understood somewhat broader, including not only the damaging physical effects, but also a traumatic experience (trauma), which in its optimal expression may occur in flashback, everyday life, experiences when watching movies, etc. In this sense, the separation of the concepts of "exposure" and "response" is very conditional. State of "optimal emotional reaction" characterized by a sense of satisfaction, excitement, excitement. Subject's behavior is subordinated to the desire to reach this state and in this state. Strong motivation (as a factor in the situation) can expand the "area of ??positive emotions." For example, in the state of hunger would be acceptable as a more acute and more fresh food than usual. Avoiding the damaging effects (stimulus) both in its excessive, and the manifestation of the weak, leads to the fact that, for each specific situation is determined by its optimum level of exposure. Severe traumatic exposure (experience) that can not be avoided, would be driven out and displaced, in the presence of a dominant motivation, inverted.
