Environmental contributions to cognitive development: The role of cognitive stimulation

Early environmental experiences influence children’s cognitive and neural development. In particular, cognitive stimulation, defined as environmental inputs that engage the senses and provide learning opportunities for children, fosters acquisition of knowledge across various cognitive domains. Low levels of cognitive stimulation in early life may restrict learning opportunities, contributing to lasting consequences for neural development and later academic and occupational achievement. This review delves into the role of cognitive stimulation in neural development and related cognitive performance, available tools for measuring cognitive stimulation in various settings, and offers insights into future research directions. In addition, variability in cognitive stimulation, often linked to differences in socioeconomic status, may create disparities in children’s access to enriching experiences that provide the foundation for learning. We therefore briefly review the role of socioeconomic status in cognitive stimulation and cognitive development. We also leverage evidence from intervention studies to illustrate the importance of cognitive stimulation for children’s outcomes. Investigating the influence of cognitive stimulation on children’s brain and behavior development is crucial for developing effective intervention strategies to foster the healthy development of all children and unlocking their full potential.
