Large language models can simulate communicative behaviors based on cognitive models. Check out our new work to see how it mimics the way patients with mental health disorders speak.
(1/n) Can large language models simulate patients with mental health conditions?
We introduce Patient-Ψ🤖, where we integrate cognitive modeling with LLMs to simulate patients for training mental health professionals.

In our
#EMNLP2023
paper, we demonstrate LLMs can effectively analyze maladaptive thought patterns from mental health issues, as to assist cognitive behavior therapy. Curious to find out to what extent language can represent human psychological constructs and cognition functions.
Using large language models in psychology:
💡 LLMs have the potential to advance psychological measurement, experimentation and practice.
💡 LLM generated on-topic, grammatically correct useless information, but not based on research and psychology construct.
💡A critical

Love this movie version of Rick & Morty.
Michelle Yeoh won the best actress for her role in “Everything, Everywhere All at Once.” The victory makes her the first Asian star to win best actress in the 95-year history of the Academy Awards.

I’ll tell myself “let’s think step by step” every time I confront something hard.
Large Language Models are Zero-Shot Reasoners
Simply adding “Let’s think step by step” before each answer increases the accuracy on MultiArith from 17.7% to 78.7% and GSM8K from 10.4% to 40.7% with GPT-3.

Current models like GPT3 fail drastically on our dataset, posing great challenges in modeling long-range, complex numerical reasoning paths. How to incorporate large language models into such real-world application domains should be one important next research focus. (2/3)

We find that LLMs can effectively analyze people’s thoughts by distinguishing subjective/objectives, elaborating supporting/contradicting evidence, and summarizing underlying thought schemas. Through these stages, it can predict cognitive distortions based on patients’ speech

Mental illness remains one of the most critical public health issues of our time, due to the severe scarcity and accessibility limit of professionals. In the era of Large Language Models, we believe it is the right time to develop AI assistance for computational psychotherapy.

As we navigate the potential of LLM in psychotherapy, we should always take caution for such development. Our foremost priority should remain on building systems that are safe and responsible. The partnership between professionals and AI systems is a promising direction for the

will significantly benefit psychotherapy and computational psychiatry. We expect to build powerful LLM agent to assist therapists, to cope with the global mental health crisis and the shortage of professionals.
Diagnosis of Thought (DoT) Prompting is a 3-stage framework that provides step-by-step guidance for an AI system to detect cognitive distortions from a patient's speech.
Stage 1 - Subjectivity Assessment: Separate objective facts from subjective thoughts and opinions.

NLP + psychology. I’ve studied both lol. For example, to analyze the mental disorders, trauma, cause of depression, mental process, etc etc, based on people’s speech. Tho most therapists can not even do this really well.
