Document Summary
The dogs learned that the tone predicted meat powder, and eventually just hearing the tone alone could elicit salivation: higher order conditioning: a neutral stimulus can become a conditioned stimulus by being paired w/ an established conditioned stimulus. Conditioned stimulus: a once-neutral stimulus that later elicits a conditioned response bc it has a history of being paired w/ an unconditioned stimulus. After repeatedly paired w/ the unconditioned stimulus, the once neutral tone became a cs bc it elicited the conditioned response of salivation. To establish that conditioning has taken place, the tone must elicit salivation in the absence of food: unconditioned stimulus: a stimulus that elicits a reflexive response w/o learning. Unconditioned response: a reflexive, unlearned reaction to an unconditioned stimulus (cid:894)i(cid:374) pa(cid:448)lo(cid:448)"s e(cid:454)pe(cid:396)i(cid:373)e(cid:374)t, the (cid:373)eat po(cid:449)de(cid:396) eli(cid:272)ited u(cid:374)(cid:272)o(cid:374)ditio(cid:374)ed sali(cid:448)atio(cid:374)(cid:895: acquisition: the initial phase of learning in which a response is established. In classical conditioning, acquisition is the phase where a neutral stimulus is repeatedly paired w/ the unconditioned stimulus.
