The warm embrace of a mother’s affection during childhood may echo throughout a lifetime, shaping core personality traits linked to success and wellbeing well into adulthood, according to groundbreaking new research.
A study published April 17 in American Psychologist reveals that children who receive more maternal warmth between ages 5 and 10 develop higher levels of openness, conscientiousness, and agreeableness by age 18 – key traits associated with everything from educational achievement to career success and overall health.
“Personality traits are strong predictors of important life outcomes, from academic and career success to health and well-being,” said Jasmin Wertz, lead author and professor of psychology at the University of Edinburgh. “Our findings suggest that fostering positive parenting environments in early childhood could have a small but significant and lasting impact on the development of these crucial personality traits.”
The research team examined data from 2,232 British identical twins followed from birth to age 18, allowing them to control for genetic factors by comparing twins raised in the same household. Researchers recorded mothers discussing each child during home visits, with trained observers rating maternal expressions of warmth and affection.
This twin-based approach provides compelling evidence that nurturing parenting influences personality development beyond genetic predispositions. The findings particularly highlight conscientiousness – a trait strongly linked to academic and professional achievement – as responsive to maternal warmth.
Interestingly, not all personality dimensions showed the same responsiveness to mothering style. Researchers found no lasting connections between maternal affection and extraversion or neuroticism, suggesting these traits may be more influenced by peer relationships, life experiences, or genetic factors.
The implications extend beyond individual families to broader policy considerations. Wertz believes the findings support investment in parenting interventions that could yield significant social benefits.
“There are many proven ways to support parents, such as policies that improve a family’s financial situation; access to treatment for parents who struggle with mental health problems such as depression; and parenting programs that help parents build stronger relationships with their children,” she said.
While the observed effects were modest, researchers note that even small shifts in personality development could produce meaningful population-wide benefits over time, potentially helping address socioeconomic disparities in life outcomes.
The study adds to growing evidence that early childhood experiences create ripples throughout development, offering both hope and responsibility – the nurturing we provide children today may help shape who they become tomorrow.
