endowed with or prepared for. A particular kind of associative learning is easy for apes or human beings but may be extremely difficult and sometimes impossible for cats and rats. It implies that one can learn only those associations for which one is genetically prepared. Continuous vs Partial Reinforcement In experiments on learning the experimenter can arrange to deliver reinforcement according to a specific schedule.
In the context of learning, two kinds of schedules namely continuous and partial have been found very important. In continuous reinforcement the participant is given reinforcement after each target response. This kind of schedule of reinforcement produces a high rate of responding. However, once the reinforcement is withheld, response rates decrease very quickly, and the responses acquired under this schedule tend to extinguish.
Since organism is getting reinforcement on each trial, the effectiveness of that reinforcer is reduced. In such schedules where reinforcement is not continuous, some responses are not reinforced. Hence, they are called partial or intermittent reinforcement. There are several ways in which one might reinforce responses according to an intermittent schedule.
It has been found that partial reinforcement schedules often produce very high rates of responding, particularly when responses are reinforced according to ratio. In this kind of schedule, an organism often makes several responses that are not reinforced. Therefore, it becomes difficult to tell when a reinforcement has been discontinued completely and when it has merely been delayed. When reinforcement is continuous it is easier to tell when it has been discontinued.
This kind of difference has been found crucial for extinction. It has been found that extinction of a response is more difficult following partial reinforcement than following continuous reinforcement . The fact that the responses acquired under partial reinforcement are highly resistant to extinction is called partial reinforcement effect . Motivation All living organisms have survival needs and human beings, in addition, have growth needs.
Motivation is a mental as well as a physiological state, which arouses an The concept of preparedness may be best understood as a continuum or dimension, on one end of which are those
