I was last with some novel results showing differential learning of self other similarity for human vs non human agents both animals and AI.

Used an odd ball paradigm to compare EEG response to male and female underwear models compared to “dollified” versions.

Next up Jerome Vaes discussed the relationship between dehumanisation and sexual objectification.

Evidence that when distingusihing between humans doll like avatars ingroup vs outgroup faces were only only distinguished at later, contextual, stages of visual processing.

Daniela Ruzzante examines the top down and bottom up factors that modulate levels of dehumanisation.

Evidence via EEG that 9 month olds show heighten visual attention to our group faces along with greater categorisation of our group faces. Perhaps due to more stereotyping.

5 year olds selectively mirror ingroup over out group for fearful but not happy expressions.

By 9 months infants show perceptual biases that discriminate between in group and out group faces

Elisa Roberti looks at the developmental roots of dehumanisation in infant behaviour.

Presents evidence that using TMS to shut down executive function (dlpfc) but NOT social cognition (TPJ) leads people to adopt a more morally acceptable strategy. Suggests that EF may allow for dehumanisation explaining human propensity to violence compared to other species.

First up @lasanaharris.bsky.social discusses the neural networks underlying dehumanisation

Federica Meconi kicks off our symposium on exploring dehumanisation at #ICON2025

Excited to be in sunny Porto to present my newly analysed (last night) data on how perceived humanness modulates similarity learning at #ICON2025 this afternoon!
