A group of 20 students of EFL took two vocabulary tests based on L1-L2 and L2-L1 translation. The test items were target words from the students’ coursebook. These words had been previously attributed an index of dispersion (Gries 2008). Results show that those words which were more regularly distributed had a higher level of acquisition. In the light of these results, a regular and systematic introduction is recommended for vocabulary acquisition within the context of Foreign Language Learning. El presente estudio tiene como objetivo averiguar si existe una relación entre la distribución de una palabra en un texto y su adquisición receptiva y productiva. Un total de 20 estudiantes de inglés como LE realizaron dos tests de vocabulario consistentes en traducción inversa y directa de palabras clave del libro de texto que seguían. Previamente, a cada una de las palabras se les había calculado un índice de dispersión (Gries 2008). Los resultados muestran que aquellas palabras cuya distribución era más regular presentaban un grado de adquisición mayor. Por tanto, se recomienda una introducción sistemática del vocabulario para su aprendizaje dentro de un contexto de lengua extranjera. 2012-06 info:eu-repo/semantics/article Alcaraz Mármol, G.
