Final answer:
Proactive and retroactive interference can make it harder to recall new learning from memory.
Step-by-step explanation:
Interference is a factor that affects memory recall. Proactive interference occurs when old information hinders the recall of newly learned information, while retroactive interference happens when newly learned information interferes with the recall of older information. In both cases, the more difficulty you have in recalling new learning from memory, the greater the detriment to your ability to do so. Therefore, the statement is true.
