Here are some of the scariest quotes from the Washington Post page. AFAIK, each quote is substantiated in the links in the WP parent page.
But [GPS] also affect perception and judgment.
neuroscientists can now see that brain behavior changes when people rely on turn-by-turn directions.
Those who were guided by directions showed less activity in [the hippocampus] than participants who navigated without the device.
The hippocampus … becomes active only when you are engaged in navigating and not using GPS
The hippocampus is crucial to many aspects of daily life. It allows us to orient in space and know where we are by creating cognitive maps. It also allows us to recall events from the past, what is known as EPISODIC MEMORY. And … it is the part of … the brain that … gives us the ability to imagine ourselves in the future.
Studies have long shown [that] the hippocampus is highly susceptible to experience.
atrophy in [the hippocampus] is linked to devastating conditions, including post-traumatic stress disorder and Alzheimer’s disease.
when people use tools such as GPS, … their brain areas involved in navigation tend to shrink.
using spatial-memory strategies for navigation correlates with increased gray matter in the hippocampus
improving spatial memory by exercising the hippocampus - paying attention to the spatial relationships of places in our environment - might help offset age-related cognitive impairments or even neurodegenerative diseases.
If we are paying attention to our environment, we are stimulating our hippocampus, and a bigger hippocampus seems to be protective against Alzheimer’s disease
When we get lost, it activates the hippocampus…Done safely, getting lost could be a good thing.
