Inhibitory control plays a crucial role in cognitive functioning. We aimed to investigate the efficacy of a program for attentive rehabilitation of inhibition and selective attention (PARISA), on inhibitory control in preschool children. Thirty preschool children, (10 girls) aged six were randomly assigned to the two control and intervention groups. Flanker and Go/ No-Go tests were used to assess preschooler's inhibitory control.The analysis showed improved accuracy of the go/no-go task (P < 0.05) and the reaction time of incongruent trials in Flanker test (P < 0.05). We concluded taht Inhibitory control could be trained in younger children and PARISA is an effective program to improve inhibitory control in preschool children.
