The primacy-recency effect explains which phenomenon?

The primacy-recency effect refers specifically to the cognitive phenomenon where individuals tend to recall the first and last items in a series more effectively than those in the middle. This concept is rooted in memory psychology, where the first items benefit from increased attention and rehearsal (primacy), while the last items are still fresh in the mind at the time of recall (recency). This means that when someone listens to a speech or presentation, they are likely to remember the initial points presented as well as the concluding remarks, while details in between might not be as strongly retained.

This principle helps explain strategies for effective communication; speakers often structure their messages to include key information at the beginning or the end to maximize retention by the audience. Understanding the primacy-recency effect is essential for anyone in oral communication, as it informs how to organize content for maximum impact and memorability.
