In order to develop the habit of attending classes regularly, North Star High School had a system of giving one point for hundred percent attendance in a week. At the end of the year, the children could exchange accrued points for things of their choice. Here the school used :
MH SET - 2020, SET Exam - 2020,
Answer: C
The school used a Token economy.
In a token economy, people earn tokens or points for the target behaviour and later exchange them for backup reinforcers of their choice. Here a point is earned for each week of full attendance and the points are traded for things at the end of the year, which is exactly that arrangement.
It is a form of positive reinforcement, but option A is too general to describe the points-for-rewards system. Shaping reinforces successive approximations to a behaviour, and fading gradually withdraws prompts, neither of which happens here.
