Next-In-Line Effect: Too Busy Rehearsing to Listen

Think back to the last time you had to introduce yourself in a group — a new class, a team meeting, a workshop icebreaker. When your turn finally arrived, you probably remembered your own name and one-liner perfectly. But what did the person just before you say? Chances are, it's gone. This is the next-in-line effect: a robust impairment in recall for the person who spoke immediately before your own turn. The cause is not rudeness or indifference. It is the quiet machinery of anticipatory anxiety, running in the background and consuming cognitive resources that should have been devoted to listening.

Brenner's Original Finding

The effect was first systematically documented by Roy Brenner in 1973. In his experiments, participants sat in a circle and took turns reading items aloud from index cards — words, sentences, or brief passages. Afterwards, they were tested on their recall of all the items read aloud in the sequence. The pattern was clear: recall was significantly worse for the item read by the person directly before the participant's own turn, compared to items from earlier or later in the sequence. The "next-in-line" position — the slot just before you perform — was a memory black hole.

Brenner's interpretation centred on the concept of self-focused attention. As your turn approaches, cognitive resources are increasingly diverted toward internal processes: reviewing what you plan to say, managing anxiety about performance, monitoring how you will come across to others. The person speaking right before you is speaking during the peak of this internal rehearsal. Their words land on ears that are technically open but a mind that is already elsewhere.

The Mechanics: Anxiety and Cognitive Load

The next-in-line effect is not simply about being distracted. It taps into the intersection of two well-studied phenomena: ego threat and working memory load.

When we anticipate performing in front of others — even in low-stakes situations like a round of introductions — we activate a self-monitoring process. We pre-run the performance in our minds, checking for potential embarrassments, rehearsing the phrasing, imagining the audience's reaction. This mental simulation consumes working memory. And working memory is a limited resource: what it spends on rehearsal, it cannot spend on encoding new input from the environment. The person speaking next to you is generating new input; your working memory is busy elsewhere.

This connects to the broader literature on spotlight effect — the tendency to overestimate how much others notice and evaluate us. The spotlight effect amplifies self-consciousness in group situations, feeding precisely the kind of anxious self-focus that drives the next-in-line impairment. If you feel intensely observed, you prepare more intensely, and preparing intensely means listening less.

Studies that manipulated the level of concern about performance found, as predicted, that higher anxiety produced greater next-in-line memory deficits. Participants who were told their performance would be graded showed more pronounced recall failures than those in low-stakes conditions. The anxiety is the variable; the forgetting is the consequence.

What You Miss — and Why It Matters

In the original lab studies, what was lost was verbal content — words on index cards. In real life, what is lost is far more consequential.

Consider a job interview where candidates present in sequence to a panel. The candidate who speaks immediately before you has just offered arguments, answered questions, and framed the conversation in a way that shapes how interviewers will compare you — yet you absorb almost none of it. You go in partly blind to the frame that has just been set.

In classroom settings where students introduce themselves on the first day, the person who goes just before you typically registers not at all in your memory. You may spend years in the same cohort unable to recall their name — not because they were forgettable, but because you were rehearsing when they spoke.

In meetings and presentations, the next-in-line effect can create a subtle disconnect: the person responding to a previous speaker may respond to a version of what was said that is partly constructed from expectation rather than from what was actually said. Misunderstandings that are attributed to poor communication often stem, at least partly, from this kind of inattentive listening during anticipatory states.

The Asymmetry of the Effect

An important feature of the next-in-line effect is its asymmetry. Recall is impaired for the person speaking before you — not the people who speak after. Once you have spoken, the internal rehearsal ends, anxiety ebbs, and attention returns to the external environment. Recall for speakers who follow your turn tends to be normal or even enhanced (a kind of relief-driven engagement). This asymmetry is diagnostic: it points specifically to anticipatory processes, not to a general state of distraction throughout a group session.

This also distinguishes the next-in-line effect from the serial position effect, which predicts that middle-sequence items are remembered less well than first or last items. The next-in-line effect operates on top of serial position — it adds a specific impairment at the slot immediately preceding the self, regardless of where that slot falls in the overall sequence.

Practical Implications

For Facilitators and Teachers

If you run sessions that require participants to speak in turn — introductions, reports, presentations — be aware that participants in the "hot seat" are not fully present for the person before them. Strategies that help:

• Randomise the order late. If participants don't know when their turn is coming, they cannot begin early rehearsal. Announce the speaking order as close to the moment of speaking as possible.
• Use written notes. Asking people to jot down key points before speaking shifts the rehearsal from working memory to paper, freeing cognitive resources for listening.
• Build in a buffer. A brief pause or transition between speakers gives the just-finished next-in-line person time to decompress and re-engage before the next round.
• Ask follow-up questions. Requiring participants to comment on the previous speaker's contribution before launching into their own talk forces active encoding of what was just said.

For Participants

Recognising that you are in a cognitively compromised state when you are "on deck" is itself useful. If you know you will have poor recall for the speaker before you, you can take notes, ask them to repeat key points after you have spoken, or simply acknowledge the gap. It is not a character flaw — it is a predictable consequence of a system under anticipatory load.

Broader Context: When Self-Focus Costs Us

The next-in-line effect is a specific instance of a more general phenomenon: self-focused attention degrades performance on tasks that require outward engagement. In therapy contexts, excessive self-monitoring in social anxiety has been repeatedly identified as a mechanism that maintains — and worsens — social difficulties. Attention directed inward is attention not directed at the person you are supposed to be connecting with.

There is something almost ironic in the next-in-line effect: the very thing we worry about — how we come across to others — causes us to miss the cues that would help us interact with them more effectively. The anxiety about being perceived well makes us worse at perceiving others. And the person we miss most is the one who just preceded us — the most useful context for calibrating our own performance.

In groups, listening is an act. It requires resource allocation. The next-in-line effect is a reminder that those resources are finite, and that anxiety has first claim on them.
