Screen technology exposure and infant cognitive development: A scoping review

Area of Science:

• Developmental Psychology
• Pediatric Health
• Media Studies

Background:

• Concerns exist regarding screen exposure's impact on infant cognitive development.
• The precise effects of screen technologies on cognition in early childhood remain unclear.

Purpose of the Study:

• To conduct a scoping review of existing evidence on screen exposure and cognitive development in infants aged 0-24 months.
• To synthesize findings from studies examining the relationship between screen time and cognitive outcomes in early childhood.

Main Methods:

• Systematic search and selection of studies focusing on infants (birth to 24 months) and cognitive development.
• Inclusion criteria specified English language, age under 24 months, cognitive development, and screen exposure, excluding older articles and studies on social/motor development.
• Analysis of ten studies, including longitudinal, cross-sectional, retrospective, and prospective designs.

Main Results:

• Six of the ten reviewed studies reported correlations between screen exposure and cognitive delay.
• One study indicated positive cognitive outcomes associated with screen exposure.
• Three studies found no significant positive or negative cognitive outcomes.

Conclusions:

• Current evidence from this scoping review does not establish a causal relationship between screen exposure and cognitive harm in infants.
• While correlations with cognitive delay exist, positive cognitive outcomes have also been observed.
• Future research should prioritize the context of screen viewing over mere exposure duration and employ more rigorous methodologies.
