Eleven children with ASD and eleven with neurotypical development (NTD) participated in this study. Postural and cognitive performances for the word memorization (WM) and the semantic verbal fluency (SVF) tests were recorded during single task (ST) and DT conditions. Postural balance was evaluated in three postural conditions: Firm eyes open (Firm-EO), Firm eyes closed (Firm-EC) and Foam-EO. Motor and cognitive DT costs (DTC) were analyzed across these different cognitive and postural conditions. Results showed that, in both ASD and NTD children postural performance was significantly altered during all DT conditions, compared to the ST situation. In ASD children, the motor DTC was significantly (p < 0.001) higher while performing the SVF task than the WM in all postural conditions. Nevertheless, in the NTD group, the motor DTC was significantly (p < 0.001) higher in the SVF cognitive task only for the Foam-EO condition. When performing the WM task, the ASD group presented significantly greater DTC compared to the NTD group in the Foam-EO (p = 0.004) condition whereas there was no difference (p = 1) in the Firm-EO or the Firm-EC conditions. However, regarding the SVF task, the ASD group had higher motor DTC in all postural conditions (p < 0.001 for the Firm-EO and the Foam-EO and p = 0.008 for the Firm-EC). In conclusion, both ASD and NTD children aged 6-9 years present a mutual interference when performing concurrently postural and cognitive tasks. Based on DTCs findings, these DT effects were more pronounced in children with ASD compared to controls; and were modulated according to the postural and cognitive tasks load.
