Inhibition is one of the main executive functions, because of its fundamental role in cognitive and social development. Given the importance of reliable and computerized measurements to assessment inhibitory performance, this research intends to analyze the internal and externalcriteria of validity of acomputerized conjunction search task, to evaluate therole of perceptual inhibition. A sample of 41 children (21 females and 20males), aged between 6and 11 years old (M = 8.49, SD = 1.47), intentionallyselected from a private management school of Mar del Plata (Argentina), middlesocio-economic level wereassessed. The Conjunction Search Task from the TAC Battery, Coding and SymbolSearch tasks from Wechsler Intelligence Scale forChildren were used. Overall,results allow us to confirm that the perceptualinhibition task form TACpresents solid rates of internal and external validitythat make a validmeasurement instrument of this process.
