Final answer:
Research on semantically related memory interference involves studying semantic networks and the effects of proactive and retroactive interference, often through word pairs or related concepts.
Step-by-step explanation:
The interference of two memories that are semantically related is typically tested or studied through research on semantic networks and interference types. When examining how semantically related information affects memory, researchers consider how concepts linked in associative networks can influence the retrieval of information. For example, in retroactive interference, a new memory interferes with the recall of an old memory. Conversely, in proactive interference, an old memory interferes with the acquisition or recall of new information. Studies may involve presenting participants with semantically related word pairs or concepts and observing how the introduction of new, related information affects their ability to recall previously learned information.
