Questions: If you have been exposed to a piece of information but it did not register with you, it would be said that the information was not properly - encoded. - retrieved. - systemized. - stored.

The answer is the first one: encoded.

Explanation for each option:

• Encoded: This is the correct answer. Encoding is the process of converting information into a form that can be stored in memory. If information did not register with you, it means it was not properly encoded.
• Retrieved: This is incorrect. Retrieval refers to the process of accessing and bringing stored information into consciousness. If the information was never registered, it could not be retrieved.
• Systemized: This is incorrect. Systemizing generally refers to organizing information into a structured format, which is not directly related to the initial registration of information.
• Stored: This is incorrect. Storing refers to maintaining information in memory over time. If the information did not register, it means it was not encoded in the first place, so it could not be stored.

Summary: If you have been exposed to a piece of information but it did not register with you, it would be said that the information was not properly encoded.
