Inhibitionis one of the main Executive Functions, due to its fundamental role incognitive and social development. Objectives.This paper aims to develop two validation studies: (1) to evaluate theconvergent 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 selectedfrom a school in Mar del Plata (Argentina). The instruments were the CVST ofthe TAC (Tareas de Autorregulación Cognitiva),and Keys and Search of Symbols of the Wechsler Scale. The Study 2 analyzes thedifferences between children with and without ADHD diagnosis, and seeks toestablish those variables with greater discriminant power. A sample of 49children between 6 and 12 years of age, assigned to two groups: Clinical (ADHDcombined subtype), consisting of children belonging to specialized centers inBarcelona, ​​Spain (n=19; MAge =9, 84; SD=1.83), and Control of anincidental sample without pathology (n =30; MAge=10.27;SD=0.83). Results. Statistically significant association (χ2=7.18, p =.02) betweenperformance on the task of VST and Search of Symbols of the WISC were found. Theperformance showed significant differences between the two groups (Lambda by Wilks= .158, p <.001; AUC =.706, p <.05), for the average TR of 32 distracters. Conclusion. The CVST presents solid indexes of convergent andclinical validity that make it a valid instrument for the measurement of the perceptualinhibition.
