BIOPAC provides software and hardware that allows research teams to study physiological measures related to infants and toddlers. Here are a few notable infant and toddler studies using BIOPAC equipment to record ECG, EDA, and RSA.

A Touching Mother and Child Study

Post-natal behaviors in rats, like licking and grooming their pups, cause decreased behavioral indices of fear and depression. Would that be the same for human mothers? By acquiring ECG with a BIOPAC Data Acquisition system and running it through AcqKnowledge Software to calculate respiratory sinus arrhythmia (RSA), these scientists were able to study the correlation between touch and bond between mother and child.

Baby, Are You Listening?

A parent’s voice is usually helpful when needed to calm an upset infant down. However, could this be proven scientifically? With a BIOPAC Data Acquisition System to collect ECG signals from the infant, these researchers were able to see how specific vocal acoustic features regulated the infant’s biobehavioral state.

Lewis, Bennet I. Bertenthal, Stephen W. Porges)

The Right Key to Capture Attention

Do infants (aged 9 to 12 months old) respond to a familiar song or familiar voice? This study aimed to see what captured an infant’s attention longer. Using BioNomadix EDA leads to measure attention, the infants then heard songs sung by their own mothers and complete strangers.
