MARQUES, Louise do Nascimento et al. INHIBITORY CONTROL PROFILE IN CLINICAL AND CONTROL GROUPS: A PRELIMINARY STUDY OF STROOP AND GO/NO-GO PARADIGMS. Psicol. clin. [online]. 2025, vol.37, e001.  Epub Feb 14, 2025. ISSN 0103-5665.  https://doi.org/10.33208/pc1980-5438v037e001.

The assessment of inhibitory control, notably through the Stroop and Go/No-Go paradigms, is crucial for understanding the cognitive, behavioral, and emotional profiles of children and adolescents. This study, involving 82 participants predominantly from an outpatient child and adolescent psychiatric clinic, aims to analyze the variability of inhibitory control between clinical and control groups. Participants were categorized into three groups: (1) Autism Spectrum Disorder (ASD); (2) Intellectual and Developmental Disabilities (IDD); and (3) typically developing (control group). No differences were identified between the ASD and control groups in the Stroop task, but discrepancies were observed between the ASD and IDD groups in the first card of the Stroop task (p=.016). In the Go/No-Go task, differences emerged between the ASD and control groups, while no distinction was found between the ASD and IDD groups. When comparing the effect of sociodemographic variables (sex and age group) on performance across the three groups, only the diagnostic group composed of both clinical groups showed a significant effect (F=15.2692, p<.001). The results underscore the importance of considering task-specific demands when assessing inhibitory control, showing varying levels of demand with clinical implications, especially for autism.
