Affection, touch, play—did you have them in childhood? As an adult, your health and social skills may depend on them.

A paper in press suggests that so-called “caveman” parenting (aka primal or evolved parenting) is related to adult health, wellbeing, sociality and morality.

In a class that just finished, students read The Science of Parenting by Margot Sunderland which explained

the neurobiological underpinnings of early parenting that fosters or impedes health and wellbeing. Here are some of their summaries.

“As babies, humans are led primarily by their instincts for survival which can be referred to as the “reptilian brain” (The Science of Parenting by Margot Sunderland, 2006, p. 18). Essentially, children are born very sensitive to their needs and need someone to help take care of the needs. Children are born not only with instinctual physiological needs, but they are born with certain social needs (Narváez, 2014, p. 24-28). When these needs for belonging, bonding, shaping of emotions, and companionship are not met, then the child will develop a stress-oriented reaction system fueled at a biological level by hormones like cortisol (Narváez, 2014, p. 132 & Sunderland, 2006, p. 42). The child will begin to see the world as more threatening and will engage in safety ethic [self-protection]. If the child keeps living in stress and dissatisfaction, these negative neural pathways will solidify and the child may be more oriented toward safety ethic for the rest of his or her life. Once a habit to be very reactive develops, it is hard to break.”— Michael Langer, undergraduate “The Science of Parenting describes the power of parenting as being able to “affect the chemistry in a child’s brain to such an extent that, for the most part, her stream of inner thoughts will be self-encouraging rather than fraught with self-criticism” (Sunderland, 2006). It also describes how parenting can affect a child’s ability to live life to the fullest, develop strong will, create enduring friendships, and establish stress-regulating systems in the brain. “Sunderland refers to an infant as an “external fetus”; due to the baby’s prematurity after birth, she cannot handle the many intense emotions she feels in her mammalian brain. These emotions must be controlled by the “rational” parts of the brain, which children do not develop until they are much older. “It is crucial that parents provide the attention and affection that their child needs in order to help the infant cope with these emotions. If a parent is neglectful and non-attentive, serious consequences may ensue. When infants do not receive proper support, they are unable to develop certain pathways that allow them to manage stress and adversity later in life. Brain scans show that adults who did not receive ample support and nurturing do not have strong regulation in their higher brain systems in regards to emotional management – they even lack self-awareness (Sunderland, 2006). Brain chemistry is strongly affected by parenting: when they receive positive responses and affection, children release oxytocin and opioids, which decrease cortisol stress levels within the brain.” — Rachel Thompson, undergraduate “The book outlines how we can raise happy, emotionally balanced children with an emphasis on brain development and emotional regulation. If we do not tend to the needs of our children, they will learn that the world is a cold place that does not meet their needs. For example, if a child is left crying too often, the stress response in his or her brain will become oversensitive. High levels of stress hormones fill the brain and opioids are absent, leaving the child in pain (Sunderland, 2006. 38). Parents must tend to their children, for just holding a child will help them to sync with the parent’s autonomic nervous system. Constant hyperarousal can manifest in physical symptoms such as asthma, heart disease, digestive disorders, anxiety, depression, fatigue and many other problems (2006. 45). One’s physical health is better when there is no conflict or toxic stress.” — Angela Reilly, undergraduate

We are starting to put the pieces together between early experience and adult wellbeing. Let’s support parents in giving babies what they evolved to need—affection, synchrony and companionship.

NOTE on BASIC ASSUMPTIONS:

WHEN I WRITE ABOUT HUMAN NATURE, I use the 99% of human genus history as a baseline. That is the context of small-band hunter-gatherers. These are “immediate-return” societies with few possessions who migrate and forage. They have no hierarchy or coercion and value generosity and sharing. They exhibit both high autonomy and high commitment to the group. They have high social wellbeing. See comparison between dominant Western culture and this evolved heritage in my article (you can download from my website):

WHEN I WRITE ABOUT PARENTING, I assume the importance of the evolved developmental niche (EDN) for raising human infants (which initially arose over 30 million years ago with the emergence of the social mammals and has been slightly altered among human groups based on anthropological research).

http://www3.nd.edu/~dnarvaez/EDST.htm

The EDN is the baseline I use for determining what fosters optimal human health, wellbeing and compassionate morality. The niche includes at least the following: infant-initiated breastfeeding for several years, nearly constant touch early, responsiveness to needs so the young child does not get distressed, playful companionship with multi-aged playmates, multiple adult caregivers, positive social support, and soothing perinatal experiences.

All EDN characteristics are linked to health in mammalian and human studies (for reviews, see Narvaez, Panksepp, Schore & Gleason, 2013; Narvaez, Valentino, Fuentes, McKenna & Gray, 2014; Narvaez, 2014) Thus, shifts away from the EDN baseline are risky and must be supported with longitudinal data looking at wellbeing in children and adults. My comments and posts stem from these basic assumptions.

My research laboratory has documented the importance of the EDN for child wellbeing and moral development with more papers in the works see (my Website to download papers):http://www.nd.edu/~dnarvaez
