Answer:
Third step: Asking whether your interpretation was correct.
Explanation:
Perception checking refers to the process by which you test if your perceptions are accurate.
Perception checking can be direct or indirect:
In the example Gilberto noticed a behavior from Sara, so he asked if she was angry with him or just call.
We can say that he's given an interpretation to the behavior (she's crossing her arms because she's angry or cold), but the question actually tells us that he is ASKING her which one of these options is the correct one (or maybe neither of them is right and there's another explanation), so he is in the third step of the direct perception checking process: Asking whether your interpretation was correct.
