|“Psychologists have repeatedly shown that a single statistical factor — often called “general intelligence”—emerges from the correlations among people’s performance on a wide variety of cognitive tasks. But no one has systematically examined whether a similar kind of “collective intelligence” exists for groups of people. In two studies with 699 people, working in groups of two to five, we find converging evidence of a general collective intelligence factor that explains a group’s performance on a wide variety of tasks. This “c factor” is not strongly correlated with the average or maximum individual intelligence of group members but is correlated with the average social sensitivity of group members, the equality in distribution of conversational turn-taking, and the proportion of females in the group.” (Woolley et al., 2010, Science, p686)|
This is a website with information about my work on the social, psychological and neurobiological determinants of parenting and child development, with special emphasis on attachment, emotion regulation, differential susceptibility, and child maltreatment. Central question is whether and how parents and other caregivers shape children’s development in this era of the genome and the brain.
My research was part of PEARL –Program for Emotion regulation and Attachment Research in Leiden, the research program of the Centre for Child and Family Studies at Leiden University, the Netherlands. PEARL has been dissolved by the end of 2017, after decades of productive collaborative work with a large and enthusiastic team of colleagues and co-workers. Alan Sroufe evaluated PEARL in June 2016 as follows: “This is an extraordinary program. The team is highly productive, and the cutting edge research being carried out is of the highest quality.”
At Leiden University I am Emeritus Professor and continue to be involved in several research programs, among others the Leiden Consortium for Individual Development (L-CID; since May 2018 as Scientific Consultant), 3G Family Lab, and Father Trials.
At Erasmus University Rotterdam I am professor of human development in the Department of Psychology, Education, and Child Studies (DPECS) (See website) and one of the co-leaders of Generation R (See website). (See website).
Since October 1, 2017, I am Honorary Senior Visiting Fellow, Department of Public Health and Primary Care, School of Clinical Medicine, University of Cambridge, UK, and in 2019 Visiting Fellow at Sidney Sussex College founded by Lady Frances Sidney, with the saying ‘Dieu me Garde de Calomnie’ (Lady Frances Sidney, Countess of Sussex,1531–1589)
In 2018 I set up a company Beagle Advice, Research and Development in the domain of parenting and child development.
