Abstract This neuropsychological case study examined sensorimotor activation processes, as well as the multisensory integration process, in a 13-year-old male subject (Veer) diagnosed with mild intellectual disorder, whose brain morphology was consistent with that of Homo habilis. In accordance with Dunn’s Sensory Processing framework, this experiment tested auditory cueing, tactile error response, and visuospatial task involvement with the executive and motor learning circuit. Over the course of several days, Veer was exposed to the pre-test, intervention, and post-test phases through various activities and tasks, including flashcards, therapy cards, bead counting, target throwing, and writing. The complexity level of each task was progressively increased. The assessment compared auditory-stimulated and self-initiated motor performance, frequency of errors, and lap efficiency. Neuropsychologically, the study emphasizes the significance of the prefrontal-occipital-thalamic loop in integrating sensory signaling and motor command, with a focus on the roles of the primary auditory cortex, premotor cortex, somatosensory cortex, and the cerebellum. Post-test effectiveness was reflected in a decrease in the number of errors, faster lap times, and self-reliant task performance. The results are implied to support executive-motor integration and procedural learning in structured multisensory training to provide conclusions on the rehabilitation of populations with atypical neural development.
