Abstract: This study analyzed the effects of perceptual richness of collections of objects and pictures on the comprehension of the number word “three”. Eighty 3-year-old children, distributed randomly to one of five conditions (four interventions and a control condition), participated. A pretest (Give a Number task), three intervention sessions and partial evaluations (Point to X task), and a posttest (Give-N) were carried out over five sessions. The results show that the condition of pictures without perceptual richness (black circles) was the one that had the most positive impact on children’s performance. In addition, pictures and objects (black bottle caps) without perceptual richness, in comparison to the conditions with perceptual richness (colorful pictures of animals and building blocks), allowed for a faster and more significant advance in performance during the intervention sessions. These findings indicate that, at this age and in relation to the number word three, perceptual richness of pictures and objects has disruptive effects on cardinal comprehension. The educational implications of these results are discussed.
