Recent studies have shown that the wail of the newborn imparts recognizable physiological stress responses in adults. Conducted by a team of scientists, the study examined how 41 participants—men and women with little to no experience with young infants—reacted to 23 different recordings of baby cries. The study’s results reveal that these wails evoke emotional responses of compassion and panic in hearers. They spark an instinctual drive to protect and assist.
The study aimed to measure the variations in facial temperature among adults exposed to these recordings, shedding light on how human responses are linked to infant crying. The findings were recently released in the Journal of the Royal Society Interface, DOI 10.1098/rsif.2014.0782.
Methodology of the Study
At the same time they were looking for diversity, the researchers wanted to get a group of corners that maximized variation. The researchers intentionally chose these participants because they had little to no experience working with infants. This decision allowed the researchers to capture authentic reactions without any bias from parental experiences.
Participants were exposed to 23 different samples of baby cries. To test their hypothesis, the scientists began tracking their facial temperature with high-tech thermal imaging technology. This novel and rigorous approach allowed for a very objective measure of the ways in which the participants’ bodies suited to the emotional stimulus of baby cries.
“Our results demonstrate that the level of nonlinear phenomena (NLP) in a cry modulates the temporal dynamics of the facial thermal response in listeners, independent of their sex,” – scientists in the paper published in the Journal of the Royal Society Interface.
The study’s design aimed to explore not just whether adults felt sympathy or anxiety while hearing a baby cry, but how these feelings could be reflected physiologically through changes in facial temperature.
Emotional Triggers and Responses
Her research findings showed that hearing a baby cry activates the emotional brain. It’s not just a feeling in the gut — it produces tangible physiological responses within our bodies. As participants listened to the recordings, many experienced a surprising amount of empathy for the crying babies. Just as they encountered the anxiety, they too felt the pressing urge to step in.
These findings further indicate that no stimulus is more salient to adults than a crying baby. It calls them to account and proddingly invites them to relate to the threatened cosmic entity in pain. This new study illustrates just how closely biological responses are tied to our emotional reactions. This deep interconnection highlights the complex interplay of our biological and psychological processes.

This insight into human behavior not only enhances understanding of parental instincts but opens avenues for further research into social responses triggered by sound.
Implications for Understanding Human Behavior
The ramifications of this research go well past scientific interest in understanding why adults feel such an intense response to baby cries. Recognizing these responses can help pave the way for important conversations about child care and mental health. They can provide guidance on expanding social services that strengthen families.
Research indicates that our automatic responses to babies’ cries are hardwired in our evolutionary biology. By attending to a fussy infant, perhaps our ancestors were more likely to ensure the most vulnerable among them survived. In showing that these parenting responses are triggered in those who have never themselves been parents, the research highlights the widespread capacity for human empathy.
