A recent study published in American Psychologist reveals that affectionate mothering between the ages of 5 and 10 can significantly influence personality traits in young adults. Led by Jasmin Wertz from the University of Edinburgh, the research suggests that positive maternal parenting fosters openness, conscientiousness, and agreeableness.
The study examined data from 2,232 British identical twins, controlling for genetic and environmental factors. Trained observers assessed mothers' warmth and affection during home visits. The results indicated that twins who experienced more maternal affection were rated higher in openness, conscientiousness, and agreeableness at age 18. Interestingly, the study 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.
These findings suggest that positive mothering affects key personality traits linked to later success. Modest personality changes, particularly increased conscientiousness, could yield population-wide benefits in education, work, and health. The study highlights the potential for parenting programs to positively influence personality development and reduce disparities in life outcomes.
