Neste sentido a Psychology Today fala-nos dos resultados dos estudos realizados por Sandra Trehub da Universidade de Toronto sobre a relação vocal entre progenitores e filhos. Referido como um descoberta, os resultados não surpreendem.
Sandra Trehub, Ph.D., of the University of Toronto, recorded mothers and fathers singing to their babies and to an empty room. Though the parents were told to make the second rendition as similar to the first as possible, others listening to the tapes could easily distinguish the two. "The parents tried to duplicate their performance to their infants, and they weren't able to do it," Trehub says. It seems that most parents, especially mothers, have a special "lullaby voice" that they use in singing to their babies: high in pitch and slow in speed. The voice is partly a product of the emotion parents feel for their child—emotion that provokes involuntary changes in facial expression and body posture, which in turn affect the sound of the song. To evoke such a response, the baby must actually be present: "The expressiveness of this voice can't be faked," says Trehub.

Não quero dizer que a descoberta é inócua, porque ela vem também reforçar a questão do vinculo progenitor-cria e colocar a nú os fortes laços emocionais que nos ligam e que permitem que as espécies mamíferas subsistam e sobrevivam num mundo às vezes inóspito.
