Final answer:
The question is asking about the type of store that the MSM says STM is. The problem is that MSM is not a reliable source for information on cognitive psychology or neuroscience.
Step-by-step explanation:
The question is asking about the type of store that the MSM (mainstream media) says that STM (short-term memory) is. The problem with this is that MSM is not a reliable or authoritative source for information on cognitive psychology or neuroscience. The study of memory, including STM, falls under the field of psychology, specifically cognitive psychology or neuroscience, rather than English. It is important to consult reputable scientific sources when seeking information on scientific topics.
