Neural signature of human–dog interactions: EEG correlates from comparisons with plant and replica dog in a within-subject, cross-over randomized trial

Puntos clave

Real dog interactions generated unique oscillatory patterns distinct from plant and replica dog controls, indicating their unique impact.
Key evidence shows that interactions with dogs evoke distinct electrophysiological responses compared to non-sentient or non-living entities.
The cross-over randomized trial design allowed within-subject comparisons to elucidate brain responses during these interactions.
These findings highlight the social and emotional significance of dogs, reinforcing their potential in animal-assisted treatments.

Resumen

These findings provide novel electrophysiological evidence that interacting with a real dog elicits unique oscillatory patterns distinct from those observed with non-sentient-living or non-living-controls. The results highlight the social and emotional salience of animals and advance understanding of the neurocognitive mechanisms underlying human-animal interactions, with implications for applied contexts such as animal-assisted treatments.
