Background. Animals acquire new skills due to conditioned responses resulting from a sequence of neutral and unconditioned stimuli affecting their bodies; there is a constant time interval between the stimuli. Both stimuli become associated after a number of repetitions and animal bodies start to respond to the initially neutral stimulus as to the unconditioned one. https://www.ealisboa.com/great-save-TV-Transparent-Drip-Logo-Grip-Tape-great-pick/
