Completed projects

Children's vision of the future represented in their art work (2018-2019):  

In this project, we analyzed hundreds of elementary school children's drawings and paintings about their visions of the future, to uncover the major themes that children focus on in their artwork, and whether gender and age are related to different thematic representations. The project was done in collaboration with the Cobra Museum in Amstelveen, and with several schools. The report can be found on the Cobra website. Study conducted by Judi Mesman, Laura Doornkamp, and Anneloes Slappendel.


Hostile Attributions and Risk for Harsh Parenting (2012-2018): 

A study on predictors of mothers’ and fathers’ hostile attribution and their relation with harsh parenting practices in a socioeconomically diverse sample.  This study also focuses on triadic interactions in which mothers and fathers interact with the child at the same time. Marieke Beckerman defended her thesis on this project in 2018. Supervised by Judi Mesman, Lenneke Alink, and Sheila van Berkel.

The Role of Parenting in Early Childhood Overweight (2013-2017):

The aim of this project was to shed light on the issue of early childhood gender-differentiated socialization and gender-specific susceptibility to parenting within families in relation to disruptive behavior in boys and girls in the first four years of life. This project was funded by an ERC Starting Grant.  This project yielded four PhD theses written by: Joyce Endendijk, Sheila van Berkel, Lotte van der Pol, and Liesbeth Hallers-Haalboom. Co-supervised by Marleen Groeneveld and Marian Bakermans-Kranenburg. A follow-up of this study funded by an ERC Consolidator grant is currently under way (see ongoing projects).
