Differences between unconditioned and conditioned reflexes:
1. Unconditioned reactions are innate, hereditarily transmitted reactions, they are formed on the basis of hereditary factors and most of them begin to function immediately after birth. Conditioned reflexes are acquired reactions in the process of individual life.
2. Unconditioned reflexes are species-specific, that is, these reflexes are characteristic of all representatives of a given species. The conditioned reflexes are individual, in some animals some conditioned reflexes can be developed, in others – others.
3. Unconditioned reflexes are constant, they persist throughout the life of the body. The conditioned reflexes are unstable, they can arise, become fixed and disappear.
4. Unconditioned reflexes are carried out due to the lower parts of the central nervous system (subcortical nuclei, brain stem, spinal cord). The conditioned reflexes are mainly a function of the higher parts of the central nervous system – the cortex of the cerebral hemispheres.
5. Unconditioned reflexes are always carried out in response to adequate stimuli acting on a specific receptive field, that is, they are structurally fixed. Conditioned reflexes can form on any stimuli from any receptive field.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
