PsyDI

Introduction to PsyDI

PsyDI is a multi-modal and interactive chatbot for psychological assessments. Its objective is to explore users' potential cognitive styles through interactive analysis of their multimodal inputs, finally determining their Myers-Briggs Type Indicator (MBTI). Additionally, PsyDI offers feedback in the form of customized figures and detailed analysis for each user. We are continuously improving PsyDI, with upcoming features such as an MBTI gallery. Your feedback is valuable to us!

PsyDI can now be accessed directly via our web link.

📚 Introduction

PsyDI operates on the principle that understanding a user's expressed thoughts involves delving deeper into the underlying cognitive processes. By uncovering these cognitive processes, PsyDI can identify the user's commonly used cognitive styles and ultimately determine their Myers-Briggs Type Indicator (MBTI).

Evaluation Framework

At the core of PsyDI's evaluation process is a table of MBTI scores, following established psychological testing methods. Each row of this table represents the probability of the current user being assigned to a specific MBTI type, ranging from 0 to 100.

Process Description

PsyDI first converts the user's multimodal information into text form. The score model then evaluates these textual expressions, providing probabilities for each sentence being associated with any MBTI type. PsyDI iterates through the following three steps until determining the user's MBTI:

Post Selection: PsyDI selects the post with the highest scores under both of the two MBTI types with the Top-2 probabilities. This step aims to pinpoint the most ambiguous information and prompt further questions to clarify.
Dialog Interaction: PsyDI engages the user in multiple rounds of dialog, utilizing three interaction formats: multiple choice, forced choice, and free question and answer. All the question and answer pairs are integrated into a new post.
Table Update: PsyDI updates the MBTI score table with the new post, incorporating the insights gained from the dialog interaction.

Iterative Refinement

PsyDI iterates through these steps until it reaches a confident determination of the user's MBTI, continually refining its understanding through each interaction.

Roadmap

More multi-modal and interactive questions and examples

Running Frontend Locally

You will first need to use the environment variables defined in .env.example to run PsyDI agent.

Note: You should not commit your .env file or it will expose secrets that will allow others to control access to your various OpenAI and authentication provider accounts.

Then you need to install node.js (v18.17.0 is recommended) and npm on your machine.

After setting up all the prerequisites, you can run the following commands to start the frontend:

npm install -g pnpm
pnpm install
pnpm dev --port 3001

Your app template should now be running on localhost:3001.
