Final answer:
We remember words at the beginning of a list better due to the primacy effect in our long-term memory, as per the three-stage model of memory by Atkinson and Shiffrin. Semantic encoding aids in better retention of verbal information through a deeper level of processing. Memory recall is also enhanced by techniques that increase the distinctiveness of information.
Step-by-step explanation:
According to the three-stage model of memory, which includes sensory memory, short-term memory, and long-term memory, proposed by Atkinson and Shiffrin, we remember words at the beginning of a list better due to a phenomenon known as the primacy effect. This effect is part of our long-term memory function, which tends to favor the recall of the initial items on a list. Additionally, words that are semantically encoded, meaning associated with their meaning, are remembered better than those encoded visually or acoustically because semantic encoding involves a deeper level of processing. Enhancing memory recall can also be achieved by applying techniques like saying words out loud, which increases their distinctiveness and improves memory retention.
