Zorgt ongelijkheid voor andere toekomstdromen?
Hoe zien kinderen zichzelf? En wat krijgen ze mee van de rijkdom van anderen? Eddie Brummelman wil weten hoe kinderen economische ongelijkheid ervaren en wat dat doet met hun zelfbeeld.

Reason-giving isn't a Western invention. New in Child Development: 360 children aged 5–9 in China, Kenya & the US spontaneously gave each other reasons to settle disagreements — and did so more when they disagreed than when they agreed. academic.oup.com/chidev/advan...

Children across diverse societies exchange reasons to resolve disagreements
Abstract. The exchange of reasons in rational discourse is crucial for resolving disagreements. In a preregistered cross-cultural study, 360 5- to 9-year-o

"Mama, ik kan het zelf!" Interview 👇met NEMO-kennislink over ons onderzoek (met Eddie Brummelman @kidlab.bsky.social )waarin we zagen dat hulp er toe kan leiden dat kinderen zich minder competent voelen en minder gemotiveerd raken. www.nemokennislink.nl/publicaties/...
nemokennislink.nl
Hulp maakt kinderen minder gemotiveerd
Je zou denken dat een kind wanneer iets niet lukt, graag hulp wil. Onderzoek toont echter aan dat dit vaak averechts werkt: het demotiveert, neemt uitdaging weg en kinderen voelen zich incompetent.
