I think the Raspberry Pi is going to be fantastic, for reasons summed up very nicely by David McGloin – the availability of such a cheap and versatile barebones technology will kickstart a new generation of tinkerers and coders.
It’s worth mentioning that this kickstart wouldn’t just be limited to the newest generation currently going through their primary and secondary school educations. Should my hands-on experience of the device live up to my expectations (and the expectations of those who have bought all the units that went on sale this morning), I will be ordering a couple for each PhD student I take on. After all, what’s the point in using an expensive desktop computer running expensive software on an expensive OS to run simple psychology experiments that have hardly changed in the past 15 years? What’s the point when technology like the Raspberry PI is available for £22? Moreover, if you can get researchers to present experiments using a medium that has also helped them pick up some of the most desirable employment skills within and outwith academia, expertise with and practical experience in programming, then I think that’s a fairly compelling argument that it would be irresponsible not to.
But won’t I have missed a critical period in my students’ development from technology consumers into technology hackers?
Every psychology student can and should learn how to code (courtesy of Matt Wall), and it’s never too late. I learned to code properly in my twenties, during my postdoc. The reason it took me so long was that I had never needed to code in any serious goal-driven way before this time. Until the end of my PhD, Superlab and E-Prime had been perfectly passable vehicles by which I could present my experiments to participants. My frustration with the attempts of these experiment presentation packages to make things ‘easy’, which ended up making things sub-optimal, led me to learn how to use the much ‘harder’ Matlab and Psychophysics Toolbox to present my experiments. Most importantly, I was given license to immerse myself in the learning process by my boss. This is what I hope giving a PhD student a couple of Raspberry Pis will do, bypassing the tyranny of the GUI-driven experiment design package in the process. Short-term pain, long-term gain.
In a few years, my behavioural testing lab-space could simply be a number of rooms equipped with HDMI monitors, keyboards and mice. Just before testing participants, students and postdocswill connect these peripherals to their own code-loaded Raspberry Pis, avoiding the annoyances of changed hardware settings, missing dongles and unre
liable network licenses. It could be brilliant, but whatever it is, it will be cheap.
