The aim of the EFFORT project is to measure cognitive effort in children and understand how it relates to their socioeconomic background. To carry this out, a large sample of school children conducted different real-effort tasks in Universidad Carlos III de Madrid. This new methodology will produce the first reliable evidence of socioeconomic differences in effort. The findings will provide valuable insights for educational practitioners and help design policies aimed at improving equality of opportunity.
