At least as far back as Lev Vygotsky, psychological scientists and others interested in human cognition have considered the relationship between humans’ technology use and cognition. Vygotsky, for example, saw humans’ mediation of ‘tools and signs’ (i.e., technological innovations, both concrete and abstract) as a key part of the learning process, while psychologist Jerome Bruner argues that using technology has a recursive relationship with cognition – as we use tools to accomplish some task, our thinking about the task itself can change.
In this article from The Atlantic, writer Ross Anderson examines the growing body of technologies and methods explicitly designed for ‘cognitive enhancement:’
It could be that we are on the verge of a great deluge of cognitive enhancement. Or it’s possible that new brain-enhancing drugs and technologies will be nothing compared to how we’ve transformed our minds in the past. If it seems that making ourselves “artificially” smarter is somehow inhuman, it may be that similar activities are actually what made us human.

Crosswords can reflect the nature of intuition, hint at the way we retrieve words from our memory and reveal a surprising connection between puzzle-solving and our ability to recognize a human face.
“What’s fascinating about a crossword is that it involves many aspects of cognition that we normally study piecemeal, such as memory search and problem-solving, all rolled into one ball,” says Raymond Nickerson, a psychologist at Tufts University. In a paper published last year, he analyzed the mental processes of crossword-solving.
The Associated Press (via the Huffington Post) reports:
As planes become ever more reliant on automation to navigate crowded skies, safety officials worry there will be more deadly accidents traced to pilots who have lost their hands-on instincts in the air.
Pilots use automated systems to fly airliners for all but about three minutes of a flight: the takeoff and landing. Most of the time pilots are programming navigation directions into computers rather than using their hands on controls to fly the plane. They have few opportunities to maintain their skills by flying manually…

Behind every smart web service is some even smarter web code. From the web retailers – calculating what books and films we might be interested in, to Facebook’s friend finding and image tagging services, to the search engines that guide us around the net.
It is these invisible computations [computer algorithms] that increasingly control how we interact with our electronic world.
At last month’s TEDGlobal conference, algorithm expert Kevin Slavin delivered one of the tech show’s most “sit up and take notice” speeches where he warned that the “maths that computers use to decide stuff” was infiltrating every aspect of our lives.

Intelligence is in the genes, researchers reported Tuesday in the journal Molecular Psychology.
The international team, led by Ian Deary of the University of Edinburgh in Scotland and Peter Visscher of the Queensland Institute of Medical Research in Brisbane, Australia, compared the DNA of more than 3,500 people, middle aged and older, who also had taken intelligence tests. They calculated that more than 40% of the differences in intelligence among test subjects was associated with genetic variation.
The genome-wide association study, as such broad-sweep genetic studies are known, suggested that humans inherit much of their smarts, and a large number of genes are involved.
