Final answer:
The primacy effect is when information at the beginning of a list is remembered better, often because it is transferred into long-term memory.
Step-by-step explanation:
The effect where the first part of the information on a list is remembered is known as the primacy effect. This phenomenon occurs due to information at the beginning of a list being more effectively transferred into long-term memory, making it more likely to be recalled later. In contrast to the primacy effect is the recency effect, where the last items on the list are also remembered well because they are still present in short-term memory.
Sensory memory is responsible for storing brief sensory events, but it is the process of encoding, often through effortful encoding, that helps move the information from short-term to long-term memory. For instance, the use of mnemonic devices can assist in the REM process, making it easier to retrieve information later on.
