Tracking knappers

We have just published one more article on eye-tracking and Lower Paleolithic tools. This time, we analyzed the pattern of visual attention during tool-making. In this pilot study (one single knapper) we quantified overt visual attention when knapping choppers and handaxes. There are differences between the two visual strategies, which suggests that there are distinct visuospatial (cognitive) processes involved. The attention is distributed differently when considering the tool regions or the knapped surface. Also, visual attention displays a more homogeneous pattern for handaxes, possibly because of a more standardized procedure, while it is more variably distributed for choppers. In both cases, anyway, the blank is the main element involved (not the hammer or the flake), as well as the next region of percussion (revealing the attentional schemes of planning and prediction). Visuospatial ability can have experienced major changes during human evolution, and the quantification of the behaviors involved in this domain is hence a stimulating issue in cognitive archaeology. Here more posts on eye-tracking and Lower Paleolithic tools.

    We have published a new study on the evolution of human brain morphology by means of anatomical network analysis (Schuurman & Bruner, 2023), which permits modeling physical interactions among the brain’s morphological elements. These physical interactions inform about geometric constraints which, once untangled, reveal key regions as well as broader phen […]

    Researchers at MIT have developed a new method of electrically stimulating deep brain tissues without opening the skullSince 1997, more than 100,000 Parkinson’s Disease patients have been treated with deep brain stimulation (DBS), a surgical technique that involves the implantation of ultra-thin wire electrodes. The implanted device, sometimes referred to as […]
