Olivier Houdé, a prominent French cognitive scientist, has made major contributions to our understanding of how children think, reason, and develop intellectual control. His pioneering studies and experiments have reshaped educational and psychological approaches to child development. Drawing on both classical theories and modern neuroscience, Houdé has revealed the crucial role of inhibition and cognitive flexibility in learning. One of Houdé’s most significant series of experiments focused on cognitive inhibition the ability to suppress intuitive but often incorrect responses. In his landmark studies on logical reasoning, Houdé adapted classic Piagetian tasks such as conservation of quantity. These experiments demonstrated that errors in reasoning did not always arise from a lack of knowledge, as Piaget suggested, but rather from children’s failure to inhibit misleading intuitions. For example, when faced with two rows of coins one spaced out and one compact young children often wrongly judge the longer row as having more coins. Houdé’s research showed that as children develop, they learn to inhibit this faulty perception and apply logical analysis instead.

To explore this inhibitory process further, Houdé integrated neuroimaging techniques into his work. He conducted functional MRI (fMRI) studies where children and adults were asked to solve reasoning problems while their brain activity was recorded. These studies consistently highlighted the role of the prefrontal cortex particularly the anterior cingulate cortex in controlling intuitive responses and activating logical reasoning. Houdé’s neuroimaging work provided clear evidence that brain maturation supports the development of cognitive control.

Another key area of Houdé’s research involved training studies designed to strengthen inhibitory control and improve reasoning performance. In these interventions, children practiced tasks that required them to pause, reflect, and override their first, often incorrect, responses. The results were striking: with training, children became better at tasks like class inclusion, conservation, and conditional reasoning. These experiments demonstrated that cognitive control can be taught and that educational strategies can be designed to enhance executive functions alongside academic content.

Houdé also investigated dual-process theories of thinking through his experiments. His studies showed that children’s reasoning often involves a competition between fast, intuitive processes (System 1) and slower, deliberate reasoning (System 2). His experiments demonstrated that successful problem-solving requires children to recognize when their intuition may be misleading and activate analytical thinking. This insight has profound implications for how educators structure lessons and guide students through learning challenges.
Beyond the laboratory, Houdé’s work has influenced educational policy and practice. His research encourages schools to integrate activities that strengthen executive function, such as reflection exercises, logical puzzles, and tasks that require students to question their first impressions. These applications of his experiments have helped bridge the gap between cognitive science and classroom teaching.

The Approach at Kintess School
At Kintess, the educational approach reflects Olivier Houdé’s key findings by focusing on developing children’s cognitive control and flexibility. Teachers at Kintess design lessons that challenge students to recognize impulsive responses and engage in deeper reasoning. Through thoughtfully structured activities, students are encouraged to pause, reflect, and evaluate different problem-solving strategies. The school places particular emphasis on building executive functions like inhibition and cognitive flexibility, ensuring that children not only gain knowledge but also master the mental tools needed to apply it effectively. This alignment with Houdé’s research helps Kintess students become thoughtful, adaptable learners prepared for the complexities of modern life.
