we are happy to announce the publication of our book on Matters of Significance. Replication, Translation and Academic Freedom in Developmental Science by UCL Press (London, UK).

Below you find a brief description of the major themes.
We hope you enjoy reading the book!
From the website of UCL Press:
Application of scientific findings to effective practice and informed policymaking is an aspiration for much research in the biomedical, behavioural, and developmental sciences. But too often translations of science to practice are conceptually narrow, ethically underspecified, and developed quickly as salves to an urgent problem. For developmental science, widely implemented parenting interventions are prime examples of technical translations from knowledge about the causes of children’s mental distress. Aiming to support family relationships and facilitate adaptive child development, these programmes are rushed through when the scientific findings on which they are based remain contested and without ethical grounding of their aims.
In Matters of Significance, Marinus van IJzendoorn and Marian Bakermans-Kranenburg draw on 40 years of experience with theoretical, empirical, meta-analytic and translational work in child development research to highlight the complex relations between replication, translation and academic freedom. They argue that challenging fake facts promulgated by under-replicated and under-powered studies is a critical type of translation beyond technical applications. Such challenges can, in the highlighted field of attachment and emotion regulation research, bust popular myths about the decisive role of genes, hormones, or the brain on parenting and child development, with a balancing impact for practice and policymaking. The authors argue that academic freedom from interference by pressure groups, stakeholders, funders, or university administrators in the core stages of research is a necessary but besieged condition for adversarial research and myth busting.
What others wrote about Matters of Significance
(more on the UCL Press website)
‘This thoughtful volume is an accessible overview of the authors’ field-shaping collaborative research on attachment and an indispensable primer on differentiating between sense and nonsense in the service of producing cumulative developmental science and ethically translating its core insights.’
Glenn I. Roisman, University of Minnesota
‘The truly original arguments presented in Matters of Significance go beyond attachment, as they concern the nature of developmental science and its relation to ethical, cultural, legal and political issues.’
Jay Belsky, University of California, Davis
‘In a series of self-contained chapters, the authors provide far-ranging and accessible summaries of their decades of important research on key aspects of child-parent attachment and its replicable correlates, and close with a highly personal discussion of the politicization of science and its fraught relationship with academic freedom.’
Sarah Blaffer Hrdy, University of California at Davis
‘Attachment researchers are fortunate that their work generates so much enthusiasm among practitioners. Sometimes, though, enthusiasm has its drawbacks. In this appropriately provocative book, the authors draw from their remarkable scientific culture to caution against premature translation of research findings and advocate, instead, for what they nicely label “slow science” ‘.
Annie Bernier, University of Montreal
‘Matters of Significance offers an accessible introduction to and summation of the authors’ decades of tremendous empirical and theoretical work. The book topples widespread myths about child development and offers a challenging commentary on a changing academic world, developing an account of the position of science within democratic societies.’
Robbie Duschinsky, University of Cambridge
Just received pictures and an article about my visit in November to Kyiv in Ukraine where I gave some lectures and discussed ongoing research with faculty and students of the Bogomolets National Medical University.

Aim of the personal website
This website is about scientific work conducted on the intriguing puzzle of parenting and its influence on child development in the era of the genome and the brain. The ‘Dutch Blog‘ and ‘Nieuws‘ are in the Dutch language, as these are notes pertaining to local issues.
The banner is part of a winter landscape painted by Hendrick Avercamp (1585 – 1634), in fond memory of three wonderful Frisian Eleven Cities Skating Tours (Elfstedentochten).
Honorary Professor at the Research Department of Clinical, Educational and Health Psychology, Division Psychology and Language Sciences, Faculty of Brain Sciences, UCL, London, UK.

Sitting in the shadow of the statue of Charles Darwin in the garden of Christ’s College in Cambridge as a reminder of his immense courage and brilliant contributions
Darwin suffered from ‘bad hair days’, see Darwin quote:
Marinus van IJzendoorn studies 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 the current era of the genome and the brain.
His 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 Marinus is a Professor Emeritus (since his obligatory retirement age for his age cohort in the Netherlands) but he continues to be involved in several Leiden research programs, among others the Leiden Consortium for Individual Development (L-CID; since May 2018 as Scientific Consultant), 3G Family Lab, and Father Trials (directed by Marian Bakermans-Kranenburg, now moved to the ISPA – University Institute of Psychological, Social and Life Sciences, Lisbon, Portugal).
At Erasmus University Rotterdam he retired as a professor of human development in the Department of Psychology, Education, and Child Studies (DPECS) (See website) and became a visiting professor in the same department. He is one of the PIs of Generation R (See website). (See website). He left the Erasmus University Rotterdam with a valedictory lecture, see above.
From October 1, 2017 to October 1 2020, he was a Honorary Senior Visiting Fellow, Department of Public Health and Primary Care, School of Clinical Medicine, University of Cambridge, UK, and in 2019 he was a 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).
From 2018 to 2022 he was a visiting professor of human development at the School of Psychology, Capital Normal University, Beijing, China. He taught courses for faculty, MA and PhD students on meta-analysis of human development research and on child socio-emotional development, and was a scientific advisor for child development research.
From November 1 2020 to November 1 2025 he is appointed visiting professor at the Research Department of Clinical, Educational and Health Psychology, Division on Psychology and Language Sciences, Faculty of Brain Sciences, UCL, University of London, London, UK.
From June 1, 2022 he became a Monash University Affiliate at Psychiatry Monash Health, Monash University, Melbourne, Australia, to work with professor Megan Galbally and her team. This was updated to an Adjunct Professor position for 5 years (2023-2028 D.V.)
In October 2022 he was a visiting professor at the University of Trento, Department of Psychology and Cognitive Science.
On May 12 the valedictory lecture with his farewell to Erasmus University Rotterdam was presented. His ongoing work in Generation R is continued.
More than 15 years ago Adriana Bus and Marinus van IJzendoorn started the Lolle Nauta Foundation to work with African faculty and students in the area of education, developmental psychology and family studies. Ten African students were successfully supported in conducting their PhD studies.
In 2018 a small company Beagle Advice, Research and Development started in the domain of parenting and child development.
