The sleeper effect describes what memory pattern after some time?

• A. Remember the communicator but forget the message
• B. Forget the message
• C. Forget the communicator but remember the message
• D. Remember both the communicator and the message

Answer: (C)

The sleeper effect shows how attitudes can persist or even strengthen after a delay even as the source of the message fades from memory. Over time, people may forget who delivered the message, but they still remember the content of the message and are influenced by it. This dissociation—losing track of the communicator while retaining the message—explains why the message can continue to persuade even when the source is no longer recalled. In contrast, remembering the communicator but forgetting the message, forgetting the message altogether, or remembering both would not demonstrate this delayed, source-forgetting pattern.
