Suffix Effect

The suffix effect is the normal tendency to be unable to recall the final items from a spoken list, especially if that list is followed by unnecessary or irrelevant speech item or suffix. This is probably because the mind will fixate on the very end of the list, even if it is not actually part of the list. If you've ever had the experience of having a shopping list dictated to you, followed by some extraneous information, you will identify with this effect.
