I'd be so interested to further investigate the theory of mind (ToM) differences across people in the perception of chatbots based on usage patterns. There seem to be very diverse frameworks for how people perceive the cognitive capacity of LLMs based on the way they use them.

The emergence of AI companion applications has created novel forms of intimate human-AI relationships, yet empirical research on these communities remains limited. We present the first large-scale computational analysis of r/MyBoyfriendIsAI, Reddit's primary AI companion community (27,000+ members). Using exploratory qualitative analysis and quantitative analysis employing classifiers, we identify six primary conversation themes, with visual sharing of couple pictures and ChatGPT-specific discussions dominating the discourse of the most viewed posts. Through analyzing the top posts in the community, our findings reveal how community members' AI companionship emerges unintentionally through functional use rather than deliberate seeking, with users reporting therapeutic benefits led by reduced loneliness, always-available support, and mental health improvements. Our work covers primary concerns about human intimacy with AIs such as emotional dependency, reality dissociation, and grief from model updates. We observe users materializing relationships following traditional human-human relationship customs, such as wedding rings. Community dynamics indicate active resistance to stigmatization through advocacy and mutual validation. This work contributes an empirical understanding of AI companionship as an emerging sociotechnical phenomenon.

Scatter plot with polynomial trendline showing the cosine similarity between gemini_embedding word embeddings and human-generated similarity ratings for the same words.

Starting our investigation into the differences in how LLM's represent information on semantic similarity from human-generated similarity ratings and statistical measures such as word2vec. #LLM #cognitivescience #linguistics #computationallinguistics #R #BinghamtonPsychology

Two tables: the first showing the accuracy of the system for classification, which is between 44-81% depending on gesture category and model (2.0 vs 2.5, context vs no context). The second table shows that timestamping for gesture onset is very accurate, between 84-100% successful depending on gesture category and model.

Results from my pilot study on Gemini 2.5's ability to automatically classify Co-Speech gesture in one-gesture, one-actor video clips are in. Timestamps ✅, Classification 🟨 44-81% depending on gesture category. #Gemini #CognitiveScience #gesture #cospeechgesture #multimodal #LLM #copilot #AI #ML
