Individual development and family rituals begin in the family’s communication crucible, where infants first encounter the external world through face-to-face interaction. These immediate personal exchanges, involving eye contact and the first sounds of conversational speech, begin to form the core neurobiological and social foundations of attachment, early social cognition, and emotional development (Farroni et al., 2002; Trevarthen & Aitken, 2001; Feldman, 2007).

Trevarthen’s work on primary intersubjectivity (defined as the newborn’s innate capacity for face‑to‑face, emotionally attuned communication) shows that infants are equipped from the first days of life to see and hear, as they try to understand the world (Trevarthen & Aitken, 2001; Trevarthen, 2011; Galanaki, 2023). This shapes the brain’s emerging neurological potential, laying the earliest framework for prospective cognitive and emotional development.

These personal encounters that involve direct, multisensory, face‑to‑face exchanges that engage the infant’s visual, auditory, motor, and affective systems activate and strengthen all manner of neural circuits in the brain. The visual cortex, for example, processes the caregiver’s face and emotional expressions (Farroni et al., 2002); the superior temporal gyrus and early Wernicke‑related regions analyze the rhythm and prosody of the caregiver’s speech. Prosody is how something is said (inflections and tone), not just what is said. It conveys emotion, intention, and nuance; often shaping meaning more powerfully than the words alone. (Dehaene‑Lambertz et al., 2002); and Broca’s area begins coordinating the motor patterns that will later support babbling and speech (Imada et al., 2006). The infant needs to see and hear and feel the touch of their family.

Face-to-face communication leads to mutual imitation (one of the earliest forms of social learning) that engages mirror‑neuron‑related networks that then allow infants to mirror the actions and emotions of others onto their own developing cognitive, mental, motor, and affective systems (Meltzoff & Moore, 1997; Meltzoff, 2007).

Through repeated, reciprocal personal engagement, infants gradually come to recognize others, and this also supports the development of attachment. This developmental process is reinforced by ongoing face‑to‑face parent-infant interaction, in which eye contact, the all-important gaze, and conversational speech, along with hugs and holding, provide emotional support that helps develop the infant’s emerging mental and emotional capacity and the crucial connectivity of attachment, along with motor learning potential (Lavelli & Fogel, 2002).

Over time, these repeated, all-important face-to-face relational patterns become the basis for family rituals that organize meaning, predictability, belonging, and trust within the family (Fiese et al., 2002).

As children grow, these early relational experiences also develop and advance the emergence of personal agency, shaping how individuals eventually mature and begin........
