Regret in rats (and readers)

11 03 2015

Mike passed me an interesting Nature Neuroscience paper the other day: Behavioural and neurophysiological correlates of regret in rat decision-making on a neuroeconomic task‘.

I very much liked their operationaliation of regret: the recognition that an alternative action would have yielded more reward than the one you chose, and the experimental set up was very clever. Unfortunately it’s not until you read the tiny-fonted methods that you realize they only worked with 4 rats, and so the Ps of “<<0.001” can only have been got by pseudoreplication
