In learning psychology class, we have so much fun and learned interesting knowledge. Our lecturer Madam Lihanna is a warm and caring person, with her cute gesture and communicative personality, it would be hard for us to not attend the class as her attentiveness is a sort of reinforcement for us to come to class. Madam Lihanna had given her students notes and extra reading materials for us to be prepaired, this makes the students wants to take her class Of course, sometimes the lectures could get boring but, after the lectures we usually get to do some fun activities with our group members.

   Once, Hafiz ate too much for his lunch and got sleepy and eventually slept in class, Mdm. Lihanna woke him with knocking his desk. Everybody laughed making Hafiz felt ashamed, so after that Hafiz would eat moderately so he wouldn't feel sleepy in class. Later, Ain didn't take her luch at all so a result she couldn't even concentrate in class at all. Next she have learned that she have to take her luch before coming to class.

Mali have problems in her attendance, after three times not attending the class she got a warning letter. If she is absent for another three times she would be bar from the class, so to not get the bar letter she intend to have full attendance from that moment on.

  In the class we would be given many assignments, even though it was tough but her criticism and praises made the effort worth while to do. At the end of the lesson Mdm. Lihanna would ask some question, and the person who'd answers the question can leave early. Students would concentrate in class and would compete to raise their hand so they could leave early.

The story above can be related to characteristic of positive reinforcement :

• Activity reinforcer:

               "Mdm. Lihanna would ask some question, and the person who'd answers the question can leave early. "

• Natural consequences:

               "Hafiz ate too much for his lunch and got sleepy and eventually slept in class" 

• Logical consequences:

          "she got a warning letter. If she is absent for another three times she would be bar from the class, so to not get the bar letter she intend to have full attendance from that moment on."      

• Positive feedback:

               "we would be given many assignments, even though it was tough but her criticism and praises made the effort worth while to do"

• Intrinsic reinforcer:

               "In learning psychology class, we have so much fun and learned interesting knowledge."

• Social reinforcer:

               "Our lecturer Madam Lihanna is a warm and caring person, with her cute gesture and communicative personality, it would be hard for us to not attend the class as her attentiveness is a sort of reinforcement for us to come to class."

• Material reinforcer:

              "Madam Lihanna had given her students notes and extra reading materials for us to be prepaired, this makes the students wants to take her class"
