Why you immediately forget what the person before you said
When you are sitting in a circle waiting to introduce yourself or speak, you will almost certainly forget whatever the person right before you said. This is the next-in-line effect. Because your brain is so preoccupied with preparing its own performance and managing anxiety, it temporarily blocks out external speech, failing to store it in long-term memory.
The Vanishing Words of the Preceding Speaker
In almost any meeting, classroom icebreaker, or group presentation where participants take turns speaking in a fixed sequence, a peculiar memory lapse occurs. While you can usually recall what people said several turns before you, the comments made by the individual immediately preceding your turn seem to vanish entirely. Minutes after they finish, you might struggle to remember their name, the topic they addressed, or a single detail from their contribution.
This blind spot is neither a personal lapse in etiquette nor a sign of poor general memory. It is a robust psychological phenomenon known as the next-in-line effect. When people know an upcoming turn requires public speech or performance, cognitive resources shift away from external listening toward internal preparation, causing the incoming information from the neighboring speaker to bypass memory storage altogether.
Brenner's Experiments and the Discovery of the Effect
The phenomenon was first formally documented and named by psychologist Malcolm Brenner in 1973. In his foundational experiments, participants sat in small groups and took turns reading aloud words or phrases from cards in a predetermined, circular order. After completing the round, participants were given surprise memory tests to see how many words spoken by their peers they could accurately recall.
The results revealed a clear and consistent pattern across participants. Memory recall remained relatively stable for items presented by speakers four or five turns away. However, recall began to decline sharply two turns before a participant's own turn and dropped to its lowest point for the item read by the person immediately preceding them. The data produced a distinct dip in the recall curve specifically aligned to each individual's relative position in the circle.
