REFLEXES
A reflex is an automatic response to a stimulus.
All reflexes are divided into unconditioned and conditioned ones.
An unconditioned reflex is a normal, instinctive, unlearned reaction to a stimulus that occurs naturally and is not dependent on previous experience. Unconditioned reflexes are also called inborn reflexes.
Unconditioned reflexes serve as the foundation for the rest of the nervous activity of the organism.
There are a lot of unconditioned (unlearned) reflexes. The simplest ones include swallowing, salivation, blinking, scratching, sucking (in infants), sneezing, yawning, and others.
Probably the best-known reflex is the pupillary reflex. If light is flashed near one eye, the pupils of both eyes contract. Greater intensity light causes the pupil to become smaller, whereas lower intensity light causes the pupil to become larger.
Another reflex involving the eye is known as the lacrimal reflex. When something irritates the eye, the lacrimal reflex causes nerve impulses to stimulate the lacrimal glands.
A conditioned reflex is some action or feeling that you learn to do in response to a specific situation or stimulus. It is an automatic reaction learned through training to a stimulus that does not normally elicit such response. In Pavlov’s classic experiment, dogs learned to associate the sound of a ringing bell with feeding time so that they salivated at the sound of the bell, regardless of whether or not food was given to them. Conditioned reflexes are also called acquired reflexes, behavior reflexes, or trained reflexes.
Unlike conditioned reflexes, the unconditioned reflexes are mostly stable. The conditioned reflexes are not only unstable but can be modified and extinguished.
A leading role in the performance of unconditioned reflexes is played by the lower divisions of the higher nervous system, the subcortical nuclei, brain stem, and spinal cord. Conditioned reflexes, in contrast, are a function of the cerebral cortex.
The investigation of conditioned reflexes became the basis for the theory of how organisms learn. Learning theory grew into the foundation of Behaviourism, a school of physiology that had great societal influence in the mid-20th century.
