Daily brief research updates from the cognitive sciences
Imagine if you are working and your stress levels are increasing, and then automatically soothing music is turned on to calm you down. Or alternatively if you are heading towards that after lunch dip of drowsiness and upbeat energetic music is turned on to energise you.
This sounds like a sort of mind-reading device of the future, but this is a possibility according to Rose Faghih of NYU Tandon School of Engineering – and without having any invasive electrodes or implants in your brain but through a simple skin patch!
How so you may ask?
Well skin conductance is a well-known way to measure things like stress responses. Your skin reacts very quickly at microscopic levels to things like stress and mental disturbances. We’ve known that for a long time and skin conductance measure are often used in research – it is cheap, non-invasive, and a good measure of many things.
The really tricky thing through is being able to accurately predict these brain or mind states and match these to the biological data and additionally to be able to do this in real time. For this Faghih and her team have developed much more accurate ways of modelling skin responses by mapping this to 3D modelling of sweat glands and amongst other things, how they respond, how sweat distributes, is evaporated, or reabsorbed.
This has then been used to develop accurate algorithms (which though complex require little computing power) to instantaneously predict mental states in real time. This is amazing – it uses very detailed models of how the skin responds to various scenarios and has modelled this to be able to report instantaneously on mind states. Wow!
The uses of this are multifold – the above example of work will probably not be a prime focus (or maybe only in high-risk roles such as pilots). This could include identifying peripheral neuropathy in diabetes patients, post-traumatic stress disorders, on top of multiple uses in mental health monitoring.
This sounds promising, some of you may think that this could be abused by employers. It could be, but I imagine the most obvious uses will be key health issues – in the short term – and that is a good thing.
