Categorization of alphanumeric characters by Guinea baboons : within- and between-class stimulus discrimination

Une tâche de categorisation perceptive a ete proposee a des babouins a l'aide d'un systeme informatique. En ayant recours a un protocole d'appariement symbolique, les singes devaient discriminer des caracteres alphanumeriques representant des B et des 3. Apres l'apprentissage, les singes sont capables de reconnaitre des B et des 3 presentes avec des polices differentes de celles de l'entrainement (Experience 1). Le recours a des procedures de categorisation est verifiee dans une autre etude (Experience 2) qui montre la capacite des babouins a discriminer des exemplaires appartenant a une meme categorie.
