Primacy effect

This is the tendency for the first items presented in a series to be remembered better or more easily, or for them to be more influential than those presented later in the series. If you hear a long list of words, it is more likely that you will remember the words you heard first (at the beginning of the list) than words that occurred in the middle. This is the primacy effect. You should also note that you will be likely to remember words at the end of the list more than words in the middle, and this is called the recency effect.
