Dogs Evaluate Threatening Facial Expressions by Their Biological Validity – Evidence from Gazing Patterns
Fig 3
Expression dependent looking duration distribution among eyes, midface and mouth areas.
The fixation scores for target facial features (eyes, midface and mouth) of the three facial expressions (Threatening, Pleasant and Neutral) of dogs and humans. The brackets above the bars indicate statistically significant differences among the target facial features within the species and the brackets below the bars differences among the expressions within the species (*** p ≤ 0.001, ** p ≤ 0.01, * p < 0.05, # p < 0.08).
