Abstract
Objective To investigate the relation between the use of Touch Screen Devices (TSDs), such as smartphones and tablets, and interference suppression as assessed by the Bivalent Shape Task (BST) in 5–11-year-old children. Methods Thirty-eight children from a Dutch primary school were included. Interference suppression was measured in the incongruent level of the BST. TSD use was measured by a standardized interview. The dataset was analyzed using multilevel analysis because of its nested structure. Results Children with moderate to high TSD use showed a longer reaction time (RT) as age progresses in the incongruent level (T = 2.40, p = .017), compared to children with no to low TSD use. Furthermore, an interaction between TSD use, age, gender, and the incongruent level demonstrated an increased RT in boys with moderate to high TSD use compared to boys with no to low TSD use as age increases (T = −2.23, p = .026). Conclusion The RT in response of interfering stimuli seems to be negatively influenced by TSD use as age progresses in children aged 5–11. Moreover, a gender-specific effect could be observed. Given the potential impact of these findings, more research would be helpful to further explore causal mechanisms.
