Document Summary

Crespi"s e(cid:454)peri(cid:373)e(cid:374)ts (cid:894)(cid:1005)9(cid:1008)(cid:1006)(cid:895: 3 groups were given 1, 16, 256 pellets of food in the goal box after rats ran down alleyways. Then all groups were switched to 16 pellets. Incentives as energizers: hull (1943) assumed that change of incentive does not change motivation. Motivation is a constant: crespi"s e(cid:454)peri(cid:373)e(cid:374)t pro(cid:448)ed that i(cid:374)(cid:272)e(cid:374)ti(cid:448)e e(cid:374)ergize behavior and hence influence motivation. The closer it is to the goal box, the more is the (rg-sg). This accounts for the faster running etc. which indicates more motivation: attempts to measure rg was not successful (petri et. al. Persistence of behavior: amsel was interested in the question of what if after a few reinforced trials, the rat is no longer reinforced in the goal box, amsel advocated that an unlearned frustration response occurs (rf). Earlier in the frustration process, partial frustration response (rf): these rf cause the behavior to stop and leads to other behavior which is term competing responses.
