Research summary

I am interested in understanding the memory processes underlying the ability to recognise previosuly encountered events and the mechanisms involved in the production of false memories in both younger and healthy older adults using behavioral and neuroimagines techniques, such as EEG and fMRI

Current research interests

I am currently keen on deepening my knowledge regarding the relation between Semantic memory and Episodic memory. Semantic relations between unstudied and studied items increase the probability of false recognition of the new items. Roediger and colleagues have argued for an activation/monitoring framework to account for false memories in the DRM paradigm. The second major framework used to account for false memory is the fuzzy-trace theory. This theory predates that of Roediger in accounting for false memories and suggestibility effects. The primary assumption of fuzzy-trace theory is that a verbatim trace and a gist trace result from an encoding experience, and the corresponding processes operate in parallel. A verbatim trace represents the surface form of the presented list items, whereas the gist trace represents the semantic content. False memories are attributed to gist extraction that occurs during encoding, whereas veridical memories are due to verbatim traces. The main question is: can gist memory be better understood by elaborating a computationally feature-based model of semantic memory, i.e the Conceptual Structure Account, with quantifiable conceptual structure dimensions that have been associated with distinct neural substrates?

Past research interests

I have previously studied the mechanisms in the medial temporal lobe underlying the two main processes of Familiarity and Recollection. Furthermore I was interested in studying the role of the posterior parietal cortex during High vs Low confidence responses and the associated phenomenon of Encoding-Retrieval Flip, one of the most robust effect noticeable through the fMRI. I explored the brain using innovative techniques such as the Representational Similarity Analysis (Kriegeskorte et al., 2008).
