Cet article explore l'impact du genre poétique et narratif sur la mémorisation et le niveau de la réserve cognitive des apprenants du FLE. L’objectif est de comparer la fonction de la poésie et le roman sur les capacités cognitives des apprenants pour mettre en valeur la compréhension lexicale. Dans cette optique, nous avons considéré la poésie et le roman comme un support pédagogique riche en possibilités motivationnelles, interculturelles et linguistiques. Notre étude a été menée dans le cours de la lecture des textes faciles sur deux groupes de contrôle et expérimental des étudiants en troisième semestre de licence de langue et littérature françaises à l’université Azad Islamique branche des Sciences et de la Recherche de Téhéran en Iran. Nous avons utilisé le questionnaire de l'échelle de connaissance lexicale (VKS) développé par Paribakht et Wesche (1993) pour évaluer la réserve cognitive des étudiants en ce qui concerne leurs champs lexicaux. La validité de ce questionnaire a également été confirmée par Culligan (2015). L'expérimentation menée dans cette étude est de type pré-test et post-test. Alors, nous avons examiné l'amélioration de la connaissance lexicale après l’intégration de la poésie en comparant celle du roman par l'échelle de connaissance lexicale (VKS). Les résultats indiquent clairement que le genre littéraire avait un effet positif sur le niveau de la réserve cognitive et plus précisément la poésie avait un effet plus efficace que le roman sur la mémorisation des mots et elle est plus facile à retenir en raison de son rythme et de la relation émotionnelle qu'elle établit avec les étudiants.
