Primacy effect and recency effect are also observed in serial recall. The memory recall decreases when the items increase on the list. It is nevertheless important when assessing memory capability of such patients that a variety of tasks be administered, tapping memory for different types of information. As a result, they may remember some details but not others. Retrograde amnesia prevents patients from being able to recall memories from before their injury or the onset of their illness. It has been seen in different studies that more recently happened events are more easily remembered in order.
