Document Summary
Theories of reinforcement: hull, reinforcers satisfy the biological needs of the organism. Implausible drives: will the animal work for it, monkey hits lever to open a window to see a toy train moving around. Suggests that it is a drive- but is it really: are all of these drives plausible, circularity, implausible drives, drive reduction is not necessary, premack. The only way we can tell that it is a drive is the reinforcement. Drive can explain behavior over a variety of different situations. Hullians say you have to meet the biological need; if you don"t, Rats will run in a t-maze for saccharine, though it does not help then you wont learn with a biological need. Problems with premack"s approach: response deprivation theory (timberlake & allison) Sometime a more likely r does not reinforce a less likely r. Everything is stated within relative probabilities: but some behaviors are hard to measure. There are a lot of behaviors like this.
