Final answer:
Mandy's ability to recall past incidents of anger when she is currently angry is likely influenced by state-dependent memory, where the emotional state during memory formation and retrieval is similar.
Step-by-step explanation:
The phenomenon that Mandy is experiencing when she easily recalls past incidents of anger towards her boy friend during moments of current anger is most likely influenced by state-dependent memory.
This type of memory suggests that people are better at retrieving information when they are in the same state of consciousness or emotion as when the memory was formed.
The arousal theory supports this by stating that emotional arousal can enhance the strength of memories; hence, strong emotions associated with these angry incidents create particularly strong and persistent memories.
