Final answer:
The memory in this example is an instance of context-dependent memory.
Step-by-step explanation:
This is an example of context-dependent memory. Context-dependent memory refers to the phenomenon where we are more likely to remember information when we are in the same physical or emotional state that we were in when we encoded that information. In this case, Paige remembered where she left her purse when she was in a similar emotional state (laughing) as when she originally put her purse under the couch during the comedy show on TV.
