Answer:
The characteristic of preoperational thought that involves a child thinking that once something has occurred, it cannot be undone is referred to as irreversibility.
Explanation:
- Children are often observed to have beliefs that they have formed after mere dictations given by someone else. These beliefs tend them to think in a particular way and defy all the other facts that they come across.
- The preoperational thought of irreversibility makes children think that once an incident has taken place and caused a certain effect, it cannot be reversed to bring it back to the position that it was before.
