RESUMO
Study was carried out to find the existence, form of presentation and commonalities and individual differences in the mental representation of natural whole numbers (REMENEN). The design used was an ex-post-factor exploratory and descriptive field study. A questionnaire was developed and administered to a sample of 153 senior students at the Universidad Católica Andres Bello (UCAB). The hypotheses were: a) that REMENEN exists in all individuals, b) that REMENEN are individual, c) that there are intergroup differences and intragroup similarities in REMENEN according to major field of study and sex. The existence of REMENEN in the great majority of individuals was demonstrated as well as their individuality in all subjects. There were no significant differences according to major or sex, and no significant intragroup similarities. The present study opens the field for a new line of research and allows a relationship between isolated statements regarding numbers made by Galton, Jung and some cognitive psychologists.
