AFC Lab Talk Series

We host a virtual talk series on Thursdays at 1600 CET. Our aim: to support early-career researchers and underrepresented groups by providing a platform for their work and increasing networking opportunities.

If you'd like to give a talk, drop us a message and we'll get it organised.

For details on how to access the talks and view the event schedule, see the World Wide Neuro site.

Age-related dedifferentiation across representational levels and their relation to memory performance
Ruhr-University Bochum
Episodic memory performance decreases with advancing age. According to theoretical models, such memory decline might be a consequence of age-related reductions in the ability to form distinct neural representations of our past. In this talk, I want to present our new age-comparative fMRI study investigating age-related neural dedifferentiation across different representational levels. By combining univariate analyses and searchlight pattern similarity analyses, we found that older adults show reduced category selective processing in higher visual areas, less specific item representations in occipital regions and less stable item representations. Dedifferentiation on all these representational levels was related to memory performance, with item specificity being the strongest contributor. Overall, our results emphasize that age-related dedifferentiation can be observed across the entire cortical hierarchy which may selectively impair memory performance depending on the memory task.

Appearance-based impression formation
University of Aberdeen
Despite the common advice “not to judge a book by its cover”, we form impressions of character within a second of seeing a stranger’s face. These impressions have widespread consequences for society and for the economy, making it vital that we have a clear theoretical understanding of which impressions are important and how they are formed. In my talk, I outline a data-driven approach to answering these questions, starting by building models of the key dimensions underlying impressions of naturalistic face images. Overall, my findings suggest deeper links between the fields of face perception and social stereotyping than have previously been recognised.
