Oxytocin Boosts Empathy by Directing Eye Gaze to Faces in Emotional Situations
Intranasal oxytocin (24 IU) enhanced emotional empathy by increasing the time healthy males spent looking at faces in emotional contexts, shifting attention from bodies and backgrounds.
Quick Facts
What This Study Found
Intranasal oxytocin (24 IU) enhanced emotional empathy responses to both positive and negative emotional stimuli in the Multifaceted Empathy Task, replicating previous findings across multiple cultures.
Eye-tracking revealed the mechanism: oxytocin increased the proportion of time participants spent viewing the faces of people in the pictures and decreased time spent viewing body posture and background context.
This suggests oxytocin does not directly amplify emotional processing. Instead, it redirects visual attention toward the most informative social cue (the face), which naturally leads to stronger empathic responses.
Key Numbers
40 participants; 24 IU oxytocin; enhanced empathy for positive and negative stimuli; increased face viewing time; decreased body/background viewing
How They Did This
This was a randomized, placebo-controlled, within-subject experiment. Forty healthy male participants received either intranasal oxytocin (24 IU) or placebo on separate sessions. They completed the Multifaceted Empathy Task while eye-tracking recorded where they looked. The study was registered on ClinicalTrials.gov.
Why This Research Matters
Understanding how oxytocin enhances empathy is important for developing it as a potential treatment for social deficits in autism and other conditions. If oxytocin works by redirecting attention to faces rather than directly boosting emotional processing, that has implications for how it might be combined with behavioral therapies.
The eye-tracking mechanism provides a measurable biomarker for oxytocin's social effects.
The Bigger Picture
Understanding how oxytocin enhances empathy is critical for developing it as an autism treatment. If the mechanism is attention redirection to faces, then therapies combining oxytocin with social skills training could be particularly effective.
What This Study Doesn't Tell Us
This study included only male participants, and oxytocin's effects may differ in women. The sample size of 40, while adequate for a within-subject design, limits generalizability.
The Multifaceted Empathy Task uses pictures, which may not fully capture empathy in real-world social interactions.
Questions This Raises
- ?Does this attention-shift mechanism also occur in women?
- ?Would oxytocin help ASD patients by redirecting their gaze to faces?
- ?Is the empathy enhancement sustained with repeated dosing?
Trust & Context
- Key Stat:
- Face gaze increased oxytocin enhanced empathy by redirecting visual attention to faces, spending less time on bodies and backgrounds in emotional scenes
- Evidence Grade:
- Moderate evidence from a well-designed randomized crossover trial, though limited to male participants with n=40.
- Study Age:
- Published in 2020. Oxytocin's social effects continue to be studied, with increasing focus on individual differences in response.

Frequently Asked Questions
How does oxytocin increase empathy?
This study shows oxytocin redirects visual attention toward faces in emotional scenes. By spending more time looking at faces, people naturally pick up more emotional cues, leading to stronger empathic responses.
Could this help people with autism?
Possibly. Many people with ASD avoid looking at faces, missing important social cues. If oxytocin redirects gaze toward faces, combining it with social skills training could help improve social interaction.
