The Multiple Object-Tracking task first debuted in the cognitive sciences 35 years ago. Since then, research has sourced this paradigm to depict the phenomena of tracking multiple items simultaneously by manipulating factors that stress the limits of visual perception. The current presentation outlines and proposes an alternative use for the traditional measure. Here, we test the accuracy of the evolved and enhanced 3D-MOT paradigm to test the reliability in repeated assessment as well as the predictive validity of the task on clinically validated measures of attention and higher-order cognitive capability, such as intelligence. Additionally, this work aims to characterize individual difference factors in attention resource capacity via 3D-MOT performance. Participants (N = 400) between the ages of 6 to 30 years of age, and individuals with and without a neurodevelopmental condition (e.g., attention deficit hyperactivity disorder, intellectual disability) were administered the MOT paradigm. Performance on a separate, clinically validated measure of attention was collected using the Conners Continuous Performance task – 3rd edition (CPT-3), and similarly, IQ was measured using the Wechsler Abbreviated Scale of Intelligence – 2nd Edition. A subset of the sample (n = 120) were assessed on the 3D-MOT paradigm for a second time on a separate day. The results demonstrate a robust relationship between time 1 and time 2 of 3D-MOT performance across age, for neurotypical and neurodivergent populations. Furthermore, 3D-MOT capability explained a significant proportion of the variance in CPT-3 and IQ, particularly at higher levels of attentional load. While the indication of a neurodevelopmental condition was associated with decreased tracking capability, this difference was better accounted for by IQ. Overall, the findings have implications for the alternative use of 3D-MOT as a characterization of attention resource capacity, which is accurate, appropriate, and accessible for a neurodiverse population.
