Spatial memory critically relies on the hippocampus and people who use these strategies have greater fMRI BOLD activity and greater grey matter in the hippocampus. Our findings suggest that people with greater GPS habits may rely less on their hippocampus for navigation, as they exhibit a reduced use of spatial memory strategies, reduced cognitive mapping abilities, reduced landmark encoding, and as they have more difficulty learning navigational information. This is consistent with a recent study by Spiers’ group, in which participants who were given instructions on where to turn at decision points while navigating in a film simulation, akin to using GPS, exhibited less fMRI BOLD activity in the hippocampus than when participants self-guided and had to make decisions unaided
I’m so stoked for that to happen to the prefrontal cortex in our ChatGPT society dude, it’s gonna be so rad
