+# Computational vs Psychological Concepts - Clarification
+
+## Important Distinction
+
+This repository contains both **psychological content** and **computational examples**. It's crucial to understand that these represent fundamentally different domains:
+
+### Psychological Concepts
+- **Domain**: Human mind, behavior, cognition, and mental processes
+- **Methods**: Empirical research, clinical observation, statistical analysis
+- **Examples**: Cognitive biases, mental shortcuts, personality types, therapeutic approaches
+
+### Computational Concepts  
+- **Domain**: Computer science, algorithms, programming languages, and formal systems
+- **Methods**: Mathematical logic, algorithmic thinking, formal proofs
+- **Examples**: Programming languages (BrainFuck, Coq), Turing completeness, algorithmic complexity
+
+## Key Clarifications
+
+### 1. BrainFuck Programming Language
+The **BrainFuck** programming language examples in this repository are purely computational:
+- It's an esoteric programming language designed for minimal instruction sets
+- Despite the name containing "brain," it has **no relation** to neuroscience or psychology
+- It's included here as part of technical demonstrations, not psychological content
+
+### 2. Formal Logic (Coq)
+The **Coq** theorem proving examples:
+- Represent formal mathematical proofs about psychological concepts
+- Are computational tools for modeling psychological phenomena
+- Should not be confused with the psychological phenomena themselves
+
+### 3. Turing Completeness
+**Turing completeness** is a computational concept that refers to:
+- A system's ability to simulate any Turing machine
+- Computational universality in computer science
+- **Not** a psychological process or cognitive ability
+
+## Guidelines for Content
+
+When encountering computational examples in this repository:
+
+1. **Recognize the Context**: Distinguish between psychology content and technical demonstrations
+2. **Understand the Purpose**: Computational examples may be used to model or represent psychological concepts, but they are not the concepts themselves
+3. **Avoid Conflation**: Don't confuse computational processes with psychological processes
+
+## Repository Structure Clarification
+
+- **Psychology Files**: `.md` files containing research, theories, and observations about human psychology
+- **Computational Files**: `.py`, `.v`, `.ipynb` files and technical sections within `.md` files
+- **Mixed Content**: Some files contain both psychological content and computational representations
+
+---
+
+**Note**: Computation is a tool that can be used to study, model, or demonstrate psychological concepts, but computational processes are not equivalent to psychological processes.
