Appraisals of Cognitive Neuropsychology

Memory can be biased - here's how... As an aside, I always like to see the authors of the papers - that way, if I should ever see them at a conference, I can capitalize on my terrible source memory and approach them saying "don't I know you from somewhere?".  It also helps attribute, recognition where it is due.   Katherine Duncan Arhanti Sadanand Lila Davachi I attended a talk given by Katherine Duncan at the Rotman Research Institute (where I work).  The talk, was largely based on the findings from the Science paper that came out in July.  The talk was great - and just as importantly, so is the paper and its findings. The idea comes from neuroscience, yet the paper itself is entirely behavioral - something some of the senior faculty liked - that it was still possible to get a psychology/neuroscience paper into Science  without resorting to newfangled methods like fMRI.   Even without fMRI, the paper i...

Before we begin, some background information... It seems that networks and the idea of connectivity is on everybody's minds these days (pardon the pun).  It's a fairly safe bet to say that nearly everyone affiliated with neuroscience has more than a passing familiarity with the default mode and dorsal attention networks (i.e. see Raichle et al., 2001).  These networks are anticorrelated which is to say that when one is being more heavily accessed, the activity in the other is suppressed.  Broadly, the default mode is active at rest, during mind wandering and when thinking about the autobiographical past - it has been described as being related to internally directed attention.  The dorsal attention or task positive network on the other hand is engaged when attention needs to be directed outwards at a cognitively demanding task or situation.  From Dang et al., 2012 What about the frontoparietal cognitive control network?  This network was discove...
