ABSTRACT
Background/aim: Recent literatures are associating digital technology extensive and addictive use with physical, psychosocial and cognitive inverse consequences. This research focuses more on number of touch screen devices; age started using devices and usage time in relation to cognitive function in preschoolers. Subjects and methods: Ninety-seven typically developing preschool children of both genders with age ranges from three to five years participated in this study. The Pediatric Quality of Life Inventory™ (PedsQL™) cognitive functioning scale was used to assess the cognitive function. Results: The results of the current study revealed weak positive non-significant correlation between the age started to use touch screen devices and PedsQLTM cognition functioning scale score. There were moderate negative significant correlations between the touch screen usage time and number of used devices and PedsQLTM cognition functioning scale score (p < 0.05). Conclusion: Based on the results of the current study we can conclude that, increase touch screen usage time and availability of several devices adversely affect the cognitive function in preschoolers. Future longitudinal studies are needed to clarify the effects and the mechanisms underlying these associations on child behavior, physical, psychosocial and school functioning.
