Comparison of neural activity that leads to true memories, false memories, and forgetting: An fMRI study of the misinformation effect Carol L. Baym and Brian D. Gonsalves University of Illinois at Urbana-Champaign, Urbana, Illinois 報告：認知所碩一賴依旻輔助：葉丁瑞

Okado and Stark (2005) -Oringinal event phase (OEP) and misinfornmation phase (MP) -left hippocampus tail and left perirhinal: more activity 2 questions -OE encoding ↓→false memory ↑ -neural and psychological event →later reality-monitoring errors and consequently false memory

Method Participants -18 (9male, 9female) -19-27 (M=22.61) -right-handed -native English-speaker Exclude -2 participants -1 in final vignette

Method Stimuli OEP -50 photographs (800*600 pixels) -12 vignettes MP -critical: altered -control: fit -generic -each vignette:12, 6, 32

Method Procedure OEP MP Memory test -item memory recognition test (216Q) -conflict test (216Q)

Method fMRI data acquisition -3T -13m20s/run -318 volumes/phase fMRI data analysis -SPM5
