Key research themes
1. How do semantic memory representations contribute to the formation of false memories in semantic associative paradigms?
This theme investigates the neural and cognitive mechanisms underlying false memories induced by semantic associations, particularly using the Deese-Roediger-McDermott (DRM) paradigm. It focuses on how semantic relatedness and spreading activation within semantic memory networks contribute to the generation of false memories and the brain regions encoding this semantic similarity. Understanding these processes elucidates why nonpresented but semantically related items are falsely recalled, a phenomenon with broad implications for memory accuracy and retrieval.
2. What neural mechanisms differentiate true memories from false memories, especially regarding contextual and perceptual accuracy?
This area focuses on how the brain, particularly the hippocampus and related cortical regions, supports accurate memory retrieval and discriminates false memories arising from contextual misattribution or semantic similarity. It explores neural activity patterns preceding recall, source monitoring failures, and the distinct neurobiological substrates associated with different types of false recognition, informing our understanding of memory reliability.
3. How do cognitive and metacognitive factors such as belief, confidence, and encoding priorities influence false memory formation and subjective memory experience?
This research focus investigates the role of belief systems, subjective confidence, motivational salience (e.g., value), and metamemory judgments in shaping false memories. It addresses how memory is interpreted phenomenologically by the individual, the impact of intentional control over encoding strategies, and the potential dissociation between memory belief and vivid recollection, with implications for eyewitness testimony and clinical contexts.
