Does autonomic arousal distinguish good and bad decisions? Healthy individuals’ skin conductance reactivity during the Iowa Gambling Task

Imagining the impossible : motor representations in anosognosia for hemiplegia
Jenkinson, P.; Edelstyn, N.M.J.; Ellis, S.J. (2009)Anosognosia for hemiplegia (AHP) is characterised by poor insight or underestimation of hemiplegia after brain injury. Recent explanations of AHP have used an established ‘forward model’, which proposes that normal motor ... -
Reality monitoring in anosognosia for hemiplegia
Jenkinson, P.; Edelstyn, N.M.J.; Drakeford, J.L.; Ellis, S.J. (2009)Anosognosia for hemiplegia (AHP) is a lack of awareness about paralysis following stroke. Recent explanations use a ‘forward model’ of movement to suggest that AHP patients fail to register discrepancies between internally- ... -
The role of reality monitoring in anosognosia for hemiplegia
