Interspecies communication analysis reveals dogs adjust signals based on human responsiveness.
Key Points
The study aims to understand how dogs adjust their communication strategies during social interactions with humans, particularly in response to human attentiveness.
Modified Still-Face Paradigm was used with two non-responsive phases: still-face and face-away.
Interactions were recorded with both the owner and a familiar dog trainer.
Quantitative analyses assessed the frequency and duration of visual and facial signals.
Dogs displayed a rich repertoire of visual and facial signals, especially towards their owners.
Behavioural frequency and duration significantly decreased in non-responsive phases.
No notable differences were found between still-face and face-away phases, suggesting a carry-over effect.
