Inhibitory deficits are observed in several neurological and psychiatric disorders, which may increase the frequency of perseverative responses. There are no standard criteria to assess perseveration. The first study aimed to obtain preliminary data on how many blanks until the repetition of a number can be considered a perseveration in Random Number Generation (RNG) task. The discriminative potential of cutoff points was investigated by comparing children with Attention Deficit Hiperactivity Disorder (ADHD) and healthy children (Study 2). The instruments were: sociodemographic and health questionnaire, Conners Abbreviated Rating Scale, Raven Coloured Progressive Matrices and RNG. The sample was composed of children aged 6 to 12 years (Study 1: n= 60; Study 2: ADHD, n=9 e Controls, n=18). The children took on average 4.97 (sd=1.78) blanks to repeat a number. The criteria that considers perseveration as the repetition of a number up to five blanks after their last recall discriminated ADHD from controls. Therefore, this seems to be the most sensitive criteria to assess perseveration.Downloads
