The six faces humans use when speaking to dogs and babies

Adults will adopt the same facial expressions they use when speaking and playing with babies as they do with their pet dogs, a new study has found. Scientists from Eötvös Loránd University in Budapest, Hungary, determined humans use the same six overly animated expressions in both scenarios. Studies have previously found there is a similar cross over in the high pitched tone used to speak with pets and babies, too. The study identified six common expressions, ranging from the'special happy' face to the'mock surprise' face and the'fish' face, among the 42 participants.
