Seals listened to vocalizations (IMAGE) Max Planck Institute for Psycholinguistics Caption Seals listened to vocalizations combined based on the rhythmic principles of tempo (fast or slow), length (short or long calls), and regularity (metronomic or random rhythm). The sex of the seal producing the vocalisations was added as a non-rhythmic manipulation. Yet, the seal’s behaviour was only influenced by the rhythm of the vocalizations.
