Insights into the cognitive evolution of genus Homo: Eye-tracking analysis of stone tool recognition in trained versus novice modern humans

Key Points

• Stone tool recognition varied significantly between trained and novice modern humans, highlighting distinct cognitive adaptations.
• Key evidence indicates that trained individuals recognized tools 30% faster than novices, revealing efficiency differences in processing.
• Analyses used eye-tracking to observe visual attention and recognition patterns, linking cognition to evolutionary aspects of genus Homo.
• Findings suggest the need for deeper exploration into how training shapes cognitive evolution in humans and their tool use.
