Answer:
The Suffix Effect demonstration predicts that a participant will be more accurate in remembering the last item on the list when the suffix is a tone as compared to when the suffix is a speech.
Explanation:
The suffix effect is the inability to recall the final items from a spoken list when list is followed by an irrelevant speech item or suffix.
This is likely due to the fact that the mind will fixate on the end of the list, even if it is not actually part of the list.
