What can be an effect of belonging to an impoverished environment during childhood on IQ?

Belonging to an impoverished environment during childhood can lead to lower IQ scores on average due to several factors related to access to resources, stimulation, and educational opportunities. Environments that lack adequate educational materials, stable home conditions, nutritional support, and enriching experiences can hinder cognitive development. This is reflected in various studies that have shown a correlation between socioeconomic status and cognitive functioning. Children from impoverished backgrounds may have fewer opportunities for cognitive engagement and development, ultimately impacting their intellectual growth and performance on IQ tests. This connection highlights the importance of environmental influences on cognitive abilities during formative years.
