Do You Hear the Same? Cardiorespiratory Responses between Mothers and Infants during Tonal and Atonal Music
(Public Library of Science, 2014) Martine Van Puyvelde; Gerrit Loots; Pol Vanfleteren; Joris Meys; David C. Simcock; Nathalie Pattyn
This study examined the effects of tonal and atonal music on respiratory sinus arrhythmia (RSA) in 40 mothers and their 3month-old infants. The tonal music fragment was composed using the structure of a harmonic series that corresponds with the pitch ratio characteristics of mother-infant vocal dialogues. The atonal fragment did not correspond with a tonal structure. Mother-infant ECG and respiration were registered along with simultaneous video recordings. RR-interval, respiration rate, and RSA were calculated. RSA was corrected for any confounding respiratory and motor activities. The results showed that the infants' and the mothers' RSA-responses to the tonal and atonal music differed. The infants showed significantly higher RSA-levels during the tonal fragment than during the atonal fragment and baseline, suggesting increased vagal activity during tonal music. The mothers showed RSA-responses that were equal to their infants only when the infants were lying close to their bodies and when they heard the difference between the two fragments, preferring the tonal above the atonal fragment. The results are discussed with regard to music-related topics, psychophysiological integration and mother-infant vocal interaction processes.
SHALL WE DANCE? MUSIC AS A PORT OF ENTRANCE TO MATERNAL–INFANT INTERSUBJECTIVITY IN A CONTEXT OF POSTNATAL DEPRESSION

The present study introduces the concept of a mother-infant group therapy that makes use of music, singing, and moving to establish maternal-infant intersubjectivity. It was conducted in a residential mother-baby unit for mothers with postnatal depression and their infants over a 5-week period. Maternal-infant intersubjectivity of four dyads in relation to the group dynamics were microanalyzed for Sessions 1 and 5. We made within-session (i.e., beginning-middle-end) and between-session (Session 1 vs. Session 5) comparisons for the number of intersubjectivity moments (ISMs), total time of intersubjectivity (IST), and the mean duration of ISMs on a dyadic (i.e., own mother/infant involved) and a nondyadic level (i.e., own mother/infant not involved). In addition, three ISM levels (degree of group contribution) were distinguished. The results indicated a significant increase of ISMs/IST from Session 1 to Session 5. Within-session analyses showed that ISMs/IST significantly decreased through Session 1 and remained stable throughout Session 5. Intersubjectivity occurred mainly on ISM Level 1 during Session 1 and on ISM Level 3 during Session 5, suggesting increased dyadic autonomy and self-efficacy. The results are discussed in relation to the musical characteristics of mother-infant dyads, music improvisation techniques, group processes, and intersubjective development.
The Interplay Between Tonal Synchrony and Social Engagement in Mother–Infant Interaction

This study explores the relationship between tonal synchrony and maternal‐infant social engagement based on free‐play recordings of 15 mothers and their 3‐month‐old infants in a laboratory setting. Moment‐by‐moment analyses on a microlevel were used to study social engagement and vocal interaction. We analysed and categorized 854 vocalization periods (mother‐only vocalizations, tonal interaction periods, nontonal interaction periods, and mutual silence). Tonal synchrony was analysed in terms of harmonic and pentatonic series based on pitch frequency analyses. Social engagement was microanalyzed in terms of matched and mismatched engagement states. ANOVA‐repeated measures revealed, most importantly, a significant relationship between TIPs and social interaction repair, which indicates the importance of tonal synchrony in the flow of social engagement in mother–infant dyads. Other significant relationships were found between (a) nTIP s/mismatch–mismatch, and, (b) MOV/affect loss. As mentioned in the discussion, the findings are suggestive for clinical applications (e.g., music therapy) and warrant further research.
