Next-in-line effect: what it is and how to recognise it

The previous speaker finished. Attention turned immediately to the upcoming delivery. The content of what had just been said was gone.

When taking turns speaking in a group with a predetermined order, people tend to have poorer recall for the words spoken by the person who spoke immediately before them.

A Scene Worth Recognising

After a holiday trip, someone finds it easy to recall the standout meal, the unexpected view, and the one conversation that felt important. The long wait at the airport, the overpriced taxi, and the afternoon when nothing went right have already faded. What remains is a highlight reel — and that reel is where Next-in-line effect takes hold.

What it means and how it works

The effect is driven by attentional capture and retrieval interference: anticipating one's own turn consumes working‑memory resources, reducing the depth of processing for the immediately preceding speech. This creates a temporary bottleneck in encoding or retrieval that is specific to the adjacent prior item, consistent with a retrieval‑based account rather than a simple sensory or hearing limitation.

The next-in-line effect occurs in situations where speakers know the order in which they will speak (e.g., going clockwise around a room, drawing numbers). As a person prepares for their own upcoming turn, attention and cognitive resources are directed toward formulating their response, which interferes with the encoding or retrieval of the preceding speaker's contribution. This results in a specific memory deficit for the utterance just before one's own turn, while memory for other speakers' contributions remains relatively unaffected.

Why it matters

Understanding the next-in-line effect helps explain why information can be lost in structured discussions such as classrooms, meetings, or courtroom testimony. It informs the design of turn‑taking protocols, note‑taking practices, and training interventions aimed at improving group communication and knowledge retention.

The verified research on this pattern supports the following:

In structured turn-taking tasks, recall accuracy for the utterance spoken immediately before one's own turn is significantly lower than for utterances spoken earlier or later in the sequence.
The magnitude of the next-in-line effect increases when cognitive load is high (e.g., when participants must prepare a complex response) and decreases when the order of speaking is unpredictable.

Common misunderstandings

Misunderstanding 1: The effect is due to hearing problems or poor audio quality.

Misunderstanding 2: It impairs memory for all preceding speakers equally.

Misunderstanding 3: It only occurs in large groups.

The next time this pattern surfaces, the move is not to fight it — it is to notice it. Naming Next-in-line effect creates a moment of pause before the decision. That moment is usually enough.
