Mother-infant vocal interactions play a crucial role in the development of human language. However, comparatively little is known about the maternal role during vocal development in nonhuman primates. Here, we report the first evidence of mother-daughter vocal interactions contributing to vocal development in gibbons, a singing and monogamous ape species. Gibbons are well known for their species-specific duets sung between mates, yet little is known about the role of intergenerational duets in gibbon song development.
There has been a lot of research showing that when this relationship is strong, it confers benefits on both parties. One recent study , involving mother-daughter pairs in a somewhat stressful situation making a speech , examined the effects on both mother and daughter of being close to each other, either emotionally or physically holding hands , or both. What they found was that a good relationship meant less stress and better ability to regulate emotions, regardless of whether or not the pair were physically close. It makes sense that the reverse also holds true.
