We introduce a quantum-like (QL) mind model to explain mental processes using probability interference. An image recognition experiment confirmed this QL behavior, showing cognitive systems exhibit unique interference patterns.

Area of Science:

  • Cognitive Science
  • Psychology
  • Physics
  • Computational Neuroscience

Background:

  • Quantum mechanics principles are being explored for modeling cognitive processes.
  • Traditional models struggle to capture the nuances of mental representations and decision-making.

Purpose of the Study:

  • To present a contextualist statistical realistic model for quantum-like representations in cognitive science and psychology.
  • To investigate quantum-like structures in mental processes through cognitive experiments.
  • To introduce the concept of a "quantum-like (QL) mind".

Main Methods:

  • Development of a statistical realistic model incorporating probability interference.
  • Application of the model to analyze cognitive experiments, specifically image recognition tasks.

Related Experiment Videos

  • Statistical analysis of experimental data to identify a non-zero interference coefficient (lambda).

    • Main Results:

    • An experiment on image recognition confirmed predicted quantum-like behavior in mental processes.
    • The study identified a non-zero interference coefficient (lambda) characterizing cognitive QL-behavior.
    • The model predicts both standard (cos theta) and novel (hyperbolic cosh theta) interference patterns in cognitive systems.

    Conclusions:

    • The brain can be modeled as a quantum-like (QL) computer, distinct from true quantum computers.
    • Cognitive quantum-like behavior is characterized by a measurable interference coefficient.
    • The findings suggest that quantum-like formalisms offer a powerful framework for understanding the mind.
