Duke University, USA
J Cogn Neurosci 16:908-20. 2004..These data suggest a role for right PFC in the close monitoring of the familiarity of objects, which becomes critical when contextual recollection is ineffective in satisfying a memory demand... - Functional significance of striatal responses during episodic decisions: recovery or goal attainment?Sanghoon Han

Psychological and Brain Sciences, Duke University, Durham, NC 27708, USA
J Exp Psychol Learn Mem Cogn 31:1186-98. 2005..With sufficient response time and recent encoding, observers demand more evidence for conceptually distinctive items, perhaps because such items typically foster vivid recollection during retrieval... - Examining recognition criterion rigidity during testing using a biased-feedback technique: evidence for adaptive criterion learningSanghoon Han
Department of Psychology and Neuroscience, Duke University, Durham, North Carolina 27708 0086, USA
Mem Cognit 36:703-15. 2008..This mechanism may be fundamentally different from criterion shifts following explicit instructions and warnings, or shifts linked to manipulations of stimulus characteristics combined with feedback highlighting those manipulations... - Dissociating familiarity from recollection using rote rehearsalIan G Dobbins
Psychological and Brain Sciences, Duke University, Durham, NC 27708, USA
Mem Cognit 32:932-44. 2004..The results suggest that rote rehearsal can dissociate familiarity from recollection at the time of encoding and that item recognition cannot be fully accommodated within a one-dimensional signal detection model... - Executive control during episodic retrieval: multiple prefrontal processes subserve source memoryIan G Dobbins
