Just a Personal Space to Share My Thoughts

And currently, many of my thoughts circle around cognitive architectures.


PSI Theory

One of the game changers in cognitive architectures in my opinion.


World Model

What it needs for a machine to become conscious.


Robotics

Wouldn’t it be great if there was a sentient robot at your disposal?

Psi-Theory is a cognitive architecture developed by Dietrich Dörner and his colleagues, which aims to explain how the mind works in terms of interacting systems. Psi-Theory is based on the idea that the mind is composed of multiple interacting systems, such as perception, memory, and action, and that these systems are connected by a set of causal relations.

One of the main features of Psi-Theory is the distinction between three types of systems: psi-systems, which represent the internal states of the architecture; psi-functions, which represent the processes that operate on these states; and psi-relations, which represent the causal connections between the systems and functions.

Psi-Theory has been applied to several areas, such as problem solving, decision making, and cognitive development. Psi-Theory has been used to model a wide range of cognitive phenomena, such as the effects of working memory capacity on problem solving, the role of feedback in decision making, and the development of mathematical reasoning.

Psi-Theory is considered as a theoretical framework that could be used to generate a world model, as it provides a way to represent the different systems, their interactions and the relations between them. However, it is important to note that Psi-Theory has been developed mainly as a theoretical framework, and has not been implemented in any complete cognitive architectures yet, but it could be a starting point for a cognitive architecture able to generate a world model.

To implement Psi-Theory in a complete cognitive architecture, several key elements would need to be considered:

  1. Representation: Psi-Theory proposes a representational system based on psi-systems, psi-functions, and psi-relations. Implementing this system would require determining how to represent the different components of the architecture, such as the internal states, the processes that operate on these states, and the causal connections between the systems and functions.
  2. Processing: Psi-Theory proposes a set of processes that operate on the internal states of the architecture. These processes would need to be implemented in a way that can be executed by the architecture, such as through rule-based or connectionist processes.
  3. Adaptivity: Psi-Theory proposes that the architecture can adapt to new situations through learning and self-organization. Implementing these mechanisms would require determining how the architecture can learn from its interactions with the environment, and how it can self-organize to adapt to new situations.
  4. Interaction: Psi-Theory proposes that the architecture interacts with the environment through perception, action, and communication. Implementing these mechanisms would require determining how the architecture can perceive the environment through various senses, how it can take actions in the environment, and how it can communicate with other agents.
  5. Integration: Psi-Theory proposes that the architecture integrates information from different sources, such as from perception, memory, and reasoning. Implementing these mechanisms would require determining how the architecture can integrate information from different sources, and how it can make inferences about the environment and the relationships between different elements within it.
  6. Development: Psi-Theory proposes that the architecture develops over time, including both innate abilities and learned abilities
