It is not innate, but the reflection of the organism under certain conditions under certain conditions.

The formation of conditioned reflex is the formation or connection of the cerebral cortex, which is based on non-conditioned reflex. With conditioned reflex, animals not only reflect things that have direct physiological meaning, but also those that have indirect physiological significance. Elastic instinct can make animals for the changed things to adjust their instinctive behavior, make it easy to adapt to changes in the environment, thus than rigid instinct has more flexibility and purpose, and the body through the conditioning can not before the arrival of the stimulus itself accordingly reaction, make the body more proactive and initiative. Anyway, elastic instinct is higher biological value of variability of external things more advanced way of ordering reaction, is on the rigid instinct, extension, and the synthesis, make rigid instinct has more purposeful and flexibility The international monetary fund cut its growth forecast for the UK to 1.6 per cent this year from 1.7 per cent in October and is expected to grow by 1.5 per cent in 2018.
