The BBC Radio 4 series The Life Scientific has recently profiled three four, count’em, three four, cognitive scientists.
Because the BBC find the internet confusing I’m just going to link straight to the mp3s to save you scrabbling about on their site.
The most recent profile you can grab as an mp3 was artificial intelligence and open data Nigel Shadbolt.
The next mp3 for your list is an interview with cognitive neuroscientist and teenage brain researcher Sarah-Jayne Blakemore.
And finally, grab the mp3 of the programme on spatial memory researcher and recent Nobel prize winner John O’Keefe.
UPDATE: Thanks to those nice folks on the Twitter who told me about another edition I missed. AI scientist Maggie Boden was also profiled and you can also grab that edition as an mp3.
That’s more than an hour an a half of pure cognitive science. Use carefully. Keep away from fire. Remember, the value of your investments may go down as well as up

The whole “cognitive” model of brain and behavior function is wrong, but has pop appeal, obviously.
How is “cognition” measured in animals, duh?
