How does proactive interference affect memory retrieval?

• A. It aids in the recall of new information
• B. It prevents new memories from forming
• C. It makes it harder to form new memories due to old ones
• D. It has no effect on memory retrieval

Answer: (C)

Proactive interference occurs when older memories interfere with the retrieval of new information. This is particularly relevant when the old and new memories have similar contexts or characteristics, leading to confusion and difficulty in accessing the newly encoded information. The phenomenon illustrates how our previous experiences can overlap and create obstacles in memory processes.

When an individual is trying to recall recent information, such as a new phone number or a new fact learned in school, proactive interference from previously learned information—like an old phone number or old facts—can hinder effective recall. For example, if someone frequently uses an old phone number, that memory may intrude when they're attempting to remember the new one. This interference can lead to forgetting the new materials or confusing them with the older ones, making it more challenging to retrieve the desired information.

In contrast, proactive interference does not aid in recalling new information, prevent new memories from forming outright, or have no impact on memory retrieval. Rather, its primary effect is to complicate the process of recalling new memories due to the influence of older ones.
