Inhibition is one of the main Executive Functions, due to its fundamental role in cognitive and social development. Objectives. This paper aims to develop two validation studies: (1) to evaluate the convergent validity criteria of a computerized Conjunction Visual Search Task (CVST), and (2) to analyze the clinical validity of the same task. Methods. In study 1, 41 children (MAge= 8.49; SD=1.47) were intentionally selected from a school in Mar del Plata (Argentina). The instruments were the CVST of the TAC (Tareas de Autorregulaci¨®n Cognitiva), and Keys and Search of Symbols of the Wechsler Scale. The Study 2 analyzes the differences between children with and without ADHD diagnosis, and seeks to establish those variables with greater discriminant power. A sample of 49 children between 6 and 12 years of age, assigned to two groups: Clinical (ADHD combined subtype), consisting of children belonging to specialized centers in Barcelona, Spain (n=19; MAge = 9, 84; SD=1.83), and Control of an incidental sample without pathology (n =30; MAge=10.27; SD=0.83). Results. Statistically significant association (¦Ö2=7.18, p =.02) between performance on the task of VST and Search of Symbols of the WISC were found. The performance showed significant differences between the two groups (Lambda by Wilks= .158, p
