- Rule-dependent prefrontal cortex activity across episodic and perceptual decisions: an fMRI investigation of the criterial classification accountSanghoon Han
Department of Psychology, Duke University, Durham, NC 27701, USA
J Cogn Neurosci 21:922-37. 2009..These data indicate that LPFC responses reflect the number of executed criterial classifications or judgments, independent of the number of competing stimuli and the overt response demands of the decision task...
- 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...
- Regulating recognition decisions through incremental reinforcement learningSanghoon Han
Duke University, Durham, North Carolina, USA
Psychon Bull Rev 16:469-74. 2009..Overall, these data demonstrate that incremental reinforcement-learning mechanisms influence the degree of caution subjects exercise when evaluating explicit memories...

Department of Psychology and Neuroscience, Duke University, Durham, NC 27701, USA
Neuropsychologia 47:2261-71. 2009..If successful, this improves the match between retrieval cue and engram and facilitates performance...

- Cue- versus probe-dependent prefrontal cortex activity during contextual rememberingIan G Dobbins
Duke University, Durham, NC, USA
J Cogn Neurosci 18:1439-52. 2006..They also demonstrate that contextual remembering recruits multiple, functionally distinct PFC processes...
- Isolating rule- versus evidence-based prefrontal activity during episodic and lexical discrimination: a functional magnetic resonance imaging investigation of detection theory distinctionsIan G Dobbins
Department of Psychological and Brain Sciences, Duke University, Durham, NC 27708, USA
Cereb Cortex 16:1614-22. 2006..We discuss the mechanistic differences between same-different versus forced-choice decisions and the implications of these data for current theories of PFC activity during episodic remembering and executive control...
