Document Summary

Response strength: latency (cs -cr, over time, latency decreases, negatively accelerated. Learn more at the end: output mesures, negatively accelerated. Pair primary cs with another neutral stimulus (secondary cs) Not very effective: cs ucs bond is no longer reinforced. The cr extinguishes and fails to be produced. Over time, without pairing, it stops generating the response. Cs-ucs bond not unlearned, but covered or masked: savings and spontaneous recovery, learn it faster the second time. Degree of responding to stimulus similar to training stimulus. Generalization gradient shows how much you will respond to something related to the other thing. Association of a stimulus and a response. S-r bond is strengthened by reinforcement: thorndike"s law of effect. If u reward, response gets stronger, if you punish, response gets weaker: model, at any stimulus situation, there is a dominant response. Dominant response of cats is to scratch, push at ceiling, dig, etc: choose and reinforce some target response, press lever.
