Empathy for pain persists across live two-way video interactions and viewing of prerecorded videos
This study demonstrates that empathy for pain, encompassing behavioral, neural, and physiological responses, persists regardless of whether social interaction occurs via live two-way video or prerecorded footage, suggesting that temporal presence is not a necessary condition for empathic engagement.

Imagine you are trying to feel what someone else is feeling when they get a small, sharp pinch. Usually, we think you need to be right there in the room with them, looking them in the eye, to truly "get" their pain. But what if you are watching them on a screen instead? Does it matter if the video is happening live, or if you are just watching a recording of the same event?
This study asked that exact question. The researchers set up a scenario where 35 people (the observers) watched other people (the targets) receive a tiny, harmless electric shock. They wanted to see if the observers' brains and bodies reacted differently depending on whether they were watching a live two-way video call (like a Zoom call where you can talk back) or a prerecorded video (like watching a movie clip).
Think of it like this:
- Live Video: You are in a conversation. There is a tiny, almost invisible delay, but you feel like you are "there" with the person. This is high "temporal presence."
- Recorded Video: You are watching a past event. The information is delayed because it happened in the past. This is low "temporal presence."
The Big Surprise
The researchers guessed that watching the live video would make people feel more empathy because it feels more real and immediate. They thought watching a recording would make the empathy feel "duller" or weaker.
However, the results were like finding out that a radio broadcast of a concert feels just as moving as being in the stadium. The empathy didn't change. Whether the observers were watching a live feed or a recording, their:
- Behavior: How they acted or responded.
- Brainwaves: Specific electrical signals in their brains (called mid-frontal theta) that light up when they see pain.
- Body Sync: How their heart rates or breathing seemed to sync up with the person in pain.
...all remained the same. The "distance" of time (live vs. recorded) didn't stop the observers from feeling the other person's pain.
One Tiny Detail
There was one small difference, though. When watching the live video, the brain's "pain alarm" (the theta waves) went off a fraction of a second faster than when watching the recording. It's like hearing a siren in real life versus hearing it on a tape; you hear it slightly sooner in real life, but the feeling of alarm is the same either way.
The Bottom Line
The study suggests that you don't need to be in a perfectly "live" moment with someone to feel empathy for their pain. Your brain and body can connect with someone's suffering just as deeply through a screen as they can through a recording. The "magic" of empathy seems to work even when the connection isn't perfectly instant.
The authors also noted that one brain signal (called Mu suppression) didn't react to the pain at all, suggesting our brains have different ways of processing what we see, and not all of them are about feeling pain.
In short: You don't need to be in the same room, or even on a live call, to truly understand and share someone else's pain. The connection happens either way.
