Document Summary
Unconditioned eyeblink is often a large and rapid eyelid closure while the conditioned eyeblink is often smaller and more gradual movement. The us is an aversive event such as a brief electric shock delivered through metal bars. The unconditioned response may be to jump or flinch, temporarily stop what it was doing before the shock. The measure of conditioning is the suppression of ongoing behaviour when the cs is presented. Its ongoing behaviour can be measured, the rat is given separate task in which it can earn occasional food pellets by pressing a lever. Rats rate of pressing suddenly decreases as soon as the cs is presented, and it may only take a few lever presses during the minute that the cs is present. The amount of suppression of lever pressing is used to measure the strength of conditioning. Conditioning takes place in far few procedure than eyeblink procedure. A change in electrical conductivity of the skin-
