- The study examined the evolution of social relationships among first-year middle school students over time from cliques to circles. - Students' social networks transitioned from tight-knit cliques of close friends to larger circles of acquaintances and classmates as relationships broadened beyond initial friendship groups over the school year. - Larger circles correlated with increased cognitive load as students managed more relationships, showing that social network structure impacts cognitive resource allocation.
