Psychology says people who break eye contact while explaining something complicated may be protecting their attention

When someone suddenly looks toward the ceiling, floor or an empty corner while trying to explain something complicated, it can be easy to interpret the behavior as nervousness, dishonesty or a lack of interest. But psychological research suggests there may be a much simpler explanation: their brain is concentrating.

The behavior is known as gaze aversion, and researchers have repeatedly observed it when people are answering difficult questions, retrieving memories or performing mentally demanding tasks. Rather than necessarily indicating disengagement, looking away can reduce competing visual information and help redirect attention toward internal cognitive processing.

Psychology Says Looking Away Can Reduce Cognitive Load

One of the leading explanations comes from Cognitive Load Theory and research into attentional resources.


Human attention is limited. While having a conversation, the brain may simultaneously process another person's facial expression, eye movements, gestures and surrounding visual information while trying to construct an answer.

When the question becomes difficult, all that additional information can become distracting.


Research by psychologist Gwyneth Doherty-Sneddon and colleagues found that adults and children tend to avert their gaze more frequently when questions become cognitively demanding. The researchers proposed that looking away can help manage the cognitive load associated with processing environmental information.

So someone looking away while explaining a complicated work problem may not be avoiding you. They may simply be trying to avoid processing everything else at the same time.

Psychology Says Your Eyes Can Disconnect From the Outside World While You Think

Research by Arthur Glenberg, John Schroeder and David Robertson provides particularly strong evidence for this idea.

In experiments involving moderately difficult questions, participants frequently looked away. The researchers found that gaze aversion increased with cognitive difficulty and, importantly, that looking away actually improved performance. They suggested that averting the gaze helps disengage from environmental stimulation so cognitive resources can be directed toward internal processing.

Imagine someone asking: “Can you explain exactly what happened during that meeting three months ago?”

The person may initially look at you, then stare toward the side while searching their memory. That shift may be the brain effectively saying: “Give me a moment to retrieve this.”

Psychology Says Memory Retrieval Can Trigger Gaze Aversion

Looking away is particularly interesting when someone is trying to remember something.

A 2023 study published in Acta Psychologica examined gaze behavior while participants answered autobiographical memory questions. Researchers found that gaze aversion occurred early during memory retrieval and was associated with greater retrieval effort. It was much less common when memories came to mind spontaneously.

This suggests that gaze aversion may be connected to a shift from external attention to internal attention.

In simple terms, the person temporarily stops prioritizing what is happening around them and starts searching their own memory. That could explain why someone looks away when you ask, “What exactly did she say to you that day?”

They may not be uncomfortable with you. They may be searching their mental filing cabinet.

Psychology Says Difficult Questions Make People Look Away More

Researchers have observed the pattern across different types of questions, including arithmetic, verbal reasoning and autobiographical memory.

In one study, Doherty-Sneddon and Phelps found that question difficulty strongly influenced gaze aversion. The researchers concluded that although social factors can contribute to looking away, cognitive demands appeared to play a major role.

Another study found that looking away during demanding cognitive activities can help adults and children answer challenging mental arithmetic and verbal-reasoning questions.

This means that gaze aversion can sometimes be interpreted as a sign that someone is engaged with a difficult mental task, rather than disengaged from the conversation.

Psychology Says Your Face Can Become Another Source of Information to Process

Eye contact is socially meaningful. When you look directly at someone, you are not simply seeing their eyes. You are also processing their facial expression, reactions and subtle social cues.

That information can be useful when listening to another person, but it can become less helpful when you are trying to formulate a complicated answer.

Research on gaze aversion describes this as a possible form of attentional disengagement. When a task does not require visual information, reducing attention to visually salient stimuli may prevent unnecessary cognitive load.

For example, someone trying to explain an emotionally complicated decision may look toward the floor while constructing the right sequence of words. The absence of eye contact does not necessarily mean the absence of thought.

Psychology Says Looking Away Can Be an Active Attention Strategy

A 2017 study by Dekel Abeles and Shlomit Yuval-Greenberg examined gaze aversion during auditory mental arithmetic. Participants looked away more frequently and for longer when distracting visual motion was more salient and when the cognitive task was more difficult.

The researchers described gaze aversion as an active attentional disengagement mechanism. That is an important distinction.

Looking away may not simply happen because someone has become distracted. Sometimes the person is deliberately or automatically reducing visual distraction so that they can concentrate.

Psychology Says Looking Away Does Not Prove Someone Is Lying

This distinction is especially important because popular culture often treats eye contact as a simple lie detector. But gaze behavior is far too complicated to support such a conclusion.

Someone might look away because they are thinking, remembering, embarrassed, emotionally overwhelmed, distracted or simply accustomed to communicating that way.

Research specifically links gaze aversion with cognitive difficulty and memory retrieval, meaning that interpreting every instance of looking away as deception would be psychologically misleading. Context matters far more than one isolated eye movement.

Psychology Says The Person Looking Away May Actually Be Trying Harder

The next time someone breaks eye contact while answering a difficult question, watch what happens next.

If they look away, pause and then provide a detailed explanation, the behavior may have been part of their thinking process.

Their eyes may have temporarily moved away from the conversation because their attention needed to move inward.

Psychology therefore offers a fascinating reversal of the usual assumption: looking away does not always mean someone is avoiding the conversation. Sometimes it means they are trying harder to give you an answer.

FAQs

Why do people look away when trying to remember something?

Research suggests that gaze aversion can help reduce competing visual information while attention shifts toward internal memory retrieval. Studies have found that people look away more when memories require greater retrieval effort.

Does looking away mean someone is lying?

No. Gaze aversion has been strongly associated with cognitive difficulty and memory retrieval, so it cannot reliably be treated as evidence of deception.
