What concept is being tested when participants are asked to visualize where items are kept in their home?

The concept being tested when participants are asked to visualize where items are kept in their home relates to semantic encoding. Semantic encoding refers to the process of assigning meaning to information, which enhances its storage and retrieval in memory. In this case, participants are using their understanding of their home layout—essentially the meaning and organization of their living space—to recall and visualize the locations of various items.

When individuals create a mental image or representation of an environment they are familiar with, they tap into their knowledge and memories associated with that space, which illustrates the working of semantic encoding. This process allows them to integrate new information with already established knowledge, making it easier to remember and navigate within that specific context.
