Document Summary
They get startled again: they don"t remember what they"ve learned, normally have simple nervous systems like worms and snails. Unconditional stimulus (ucs)- a stimulus that naturally brings out or elicits reflexive behaviour/response ex: food. Unconditional response (ucr)- the response that is caused by ucs example: saliva. Conditional stimulus (cs)- neutral stimulus paired with ucs (cs + ucs) that creates a response of cs. Conditional response (cr)- the response caused by cs. Prior to conditioning: ucs ucr- salivation, cs- tone hear sound but no saliva. Conditioning: cs-tone + ucs (food in mouth) ucr (saliva) www. notesolution. com. Basic principles of classical conditioning: pavlov"s research lead to discovery of, acquisition; learning phase of classical conditioning, where cr first appears and increases in strength. intensity of ucs + the timing of the cs and ucs. only occurs when the cs no longer signals the ucs.
