Which token economy involves the learner being unaware of how many tokens are needed to exchange for a reward?

The token economy where the learner is unaware of how many tokens are needed to exchange for a reward is known as the "magic number" system. In this setup, the exact number of tokens required to access a desired item or privilege is not disclosed to the learner. This can create an element of surprise and intrigue, which may enhance motivation as learners are encouraged to keep earning tokens without knowing how many will ultimately lead to a reward.

In contrast, a transparent economy explicitly displays the number of tokens required for each reward, helping learners understand their progress and the value of the tokens they are earning. A fixed economy requires a set number of tokens for rewards, providing clear expectations but potentially reducing excitement or motivation once learners know the exact number necessary. A variable economy, while providing fluctuating token requirements, generally still gives some indication of how many tokens might be needed, differing from the uncertainty present in a magic number approach.

Overall, the magic number token economy uniquely emphasizes the aspect of surprise, which can significantly influence learner engagement and motivation.
