Besides replicating our previous study doi.org/10.1016/j.bi...
, we also made an interesting observation:
When sending an emoji per button press we found an increase in EMG activity in the corresponding facial muscle
😀 -> M. Zygomatiucs
😠 -> M- Corrugator

This work originated in a undergrad course on experimental psychology. I'm super proud of my students (and now co-authors) who continued to work on this with me - even when the course was long over

Interestingly, the two personas changed how participants evaluated the virtual agent: The extraverted model was rated as more pleasant.

The LLM was prompted to be either extraverted and talkative or introverted and less talkative.
Using the NEO-FFI as a manipulation check confirmed these differences. The extraverted model also produced more words

We used #embodied #conversational #agents in #VirtualReality.
By combining speech2text, speech-synthesis, and lip-synced animations for #Metahumans our participants engaged in real-time conversations with a virtual human
