phonological similarity effect

Similar sounding words disrupt your short-term memory.

Lists of phonologically similar words are significantly harder to memorize than lists of dissimilar-sounding words.

In studies of verbal short-term memory, participants struggle to recall sequences like 'cat, bat, mat' compared to 'cat, dog, pen.' The brain’s phonological loop creates interference because the codes used to store these items overlap during silent rehearsal.

Your internal monologue is creating its own static.
