Jacoby's experiment, in which participants made judgments, about whether they had previously seen the names of famous and non-famous people, found that inaccurate memories based on source misattributions occurred after a delay of how long?

Twenty-four hours.                                      

Explanation:

Source misattributions: The term source misattribution is also referred to as source confusion or unconscious transference. This indicates a form of memory error. The source misattribution occurs when a person doesn't remember or recall the source of certain memories. It often makes a person feels that the information is being gathered from a specif source but in reality, the source of that information is from somewhere else other than the person thinks or feels.

In the question above, the experiment conducted by Jacoby, inaccurate memories occur in the participants because of the source misattribution that occurred after a delay of twenty-four hours.
