Sex and cultural differences in children's spatial and verbal memory span

Area of Science:

• Developmental Psychology
• Cognitive Neuroscience
• Educational Psychology

Background:

• Assessing cognitive abilities like memory is crucial for understanding child development.
• Environmental factors, such as urban vs. rural settings, may influence cognitive performance.
• Investigating sex-based differences in cognitive tasks can reveal developmental variations.

Purpose of the Study:

• To compare spatial and verbal memory performance in children from urban and rural environments.
• To examine potential sex differences in these cognitive domains within the studied age group.
• To identify environmental and demographic factors affecting children's memory spans.

Main Methods:

• Utilized Corsi's block-tapping task to measure spatial span.
• Employed the Wechsler Digits Forward test for verbal span assessment.
• Collected data from 1113 children aged 4-10 years in urban and rural districts of Regione Campania.

Main Results:

• Children from urban districts demonstrated significantly better performance on both spatial and verbal span tests.
• Sex differences were observed exclusively in spatial span, with boys outperforming girls.
• Performance disparities suggest an influence of environmental context on memory development.

Conclusions:

• Urban environments may provide advantages that enhance children's spatial and verbal memory skills.
• Boys exhibit a developmental edge in spatial memory compared to girls in this age range.
• Findings underscore the importance of considering both environmental and sex factors in cognitive development research.
