This book takes a cross-disciplinary and cross-cultural look at attachment, challenging some of the assumptions built into classical attachment theory. It asks an essential question: If attachment is a universal human need, why does it look so different around the 

The editors begin with a core truth — attachment, our deep human need for closeness and security, is universal. Every child seeks connection. Every society finds ways to provide it.

But how that attachment is expressed, organized, and supported differs dramatically across cultures. Drawing on research from psychology, anthropology, and evolutionary biology, the book questions whether the classic Western model of attachment — developed largely in post-war Britain and America — can really be applied everywhere, without adaptation.

The authors set out to deconstruct some of the assumptions behind traditional attachment research, especially those that focus narrowly on the infant–mother dyad as the fundamental building block of attachment.

One of the book’s most compelling sections looks at cooperative breeding — caregiving systems where multiple people, not just biological parents, share responsibility for a child. In many societies, this form of allomaternal care — by siblings, grandparents, or community members — is not an exception but the norm.

These caregivers often have both a biological and emotional investment in the child’s survival, and their consistent presence can provide stability equal to, or sometimes even greater than, that offered by a single parent. The book suggests that attachment, in many cultures, is a network, not a dyad.

Another chapter critiques the cultural ideology embedded in how attachment theory has been formulated. It points out that what Western psychology often treats as “universal” — certain milestones, reactions, or emotional expressions — may actually reflect specific cultural values, such as independence and self-expression.

One especially thought-provoking idea is that of delayed personhood. In some societies, infants are not considered full “persons” until they reach a certain age or survive the fragile early months of life. While this can sound harsh through a Western lens, it may actually be a protective coping mechanism for mothers in societies with high infant mortality.

Attachment, then, adapts — not because love is weaker, but because the social and emotional environment demands resilience and flexibility.

The book provides ethnographic examples — including the Pirahã people of the Amazon — where attachment does not revolve around a single primary figure but rather spreads across a web of relationships.

It also shows how familiar concepts like “stranger anxiety,” “bonding,” and “belonging” can manifest very differently depending on cultural expectations. Western developmental models, it argues, may not fully capture the richness and variety of these emotional worlds.

Importantly, though, none of this dismantles John Bowlby’s foundational ideas about attachment. Instead, it adds depth and dimension to them. The book doesn’t deny that infants have universal needs for safety, security, and comfort — it simply shows that these needs can be met through many legitimate cultural arrangements.

While the book offers powerful insights, I would argue it doesn’t — and doesn’t need to — challenge the core of Attachment Theory. Infants everywhere depend first and foremost on the mother (or primary caregiver) because she is the source of food, warmth, and protection — the essential conditions for survival.

However, as societies evolve within specific cultural and economic contexts, other systems of care emerge to meet those same needs. Cooperative caregiving, for instance, often allows mothers in agrarian or economically constrained societies to return to work sooner, while still ensuring their infants’ wellbeing.

What matters most is who provides the care, the caregiver must be consistent, responsive, and emotionally invested in the child’s survival and safety. 

For me, the key takeaway is this:

• Universality lies in the needs of infants.

• Diversity lies in the ways those needs are met.

That distinction matters. It reminds us to respect other cultural systems without romanticizing them — and to question whether, in the modern West, we are truly serving our infants’ needs or simply constructing convenient narratives that justify our lifestyles.

As Western societies become increasingly individualistic — and as careers, consumerism, and productivity dominate our priorities — we risk commodifying infant care. Paid professionals and institutions may offer expertise, but they cannot replace the emotional ecosystem of family and community that traditional societies sustain.

The cooperative caregiving found in older or agrarian communities was built on relationship and reciprocity. In contrast, the contemporary outsourcing of care risks replacing connection with service — efficient, yes, but not the same as love.

Different Faces of Attachment doesn’t ask us to abandon attachment theory — it asks us to expand it. To open our eyes to the many ways love and security take shape around the world.

If attachment is indeed a universal human need, then understanding its cultural diversity isn’t a challenge to theory — it’s a way of making it whole again.

And perhaps, in revisiting these many faces of attachment, we’re also reminded to look closer at our own — the faces that greet our children each morning, and the ways we choose, or forget, to hold them.
