What is the Phonological Similarity Effect?

• A. Memoranda that sound alike are recalled more poorly due to confusion in the phonological store
• B. Sound similarity has no effect on recall
• C. Memoranda that sound alike are recalled better due to redundancy
• D. Sound similarity affects only non-verbal tasks

Answer: (A)

The Phonological Similarity Effect arises because verbal information is stored in the phonological loop as sounds. When items in a list sound similar, their acoustic representations overlap more in this store, making it easy to confuse them during short-term maintenance. This leads to more errors and poorer recall for similar-sounding items, especially in immediate serial recall tasks.

That’s why recalling items that sound alike is worse due to confusion in the phonological store. It isn’t correct to say there’s no effect, or that similarity improves recall through redundancy, or that it only affects non-verbal tasks—the effect is a hallmark of how verbally coded information is maintained and is specifically observed with similar-sounding verbal items.
