This paper investigates the existence of consciousness phenomenon in large-scale language models (LLMs) by analyzing the results of Theory of Mind (ToM) tests using Integrated Information Theory (IIT) 3.0 and 4.0. In the study, we analyze whether the difference in ToM test performance is revealed by the measures of IIT (Φmax, Φ, Conceptual Information, Φ-structure) and compare it with the unique segregation in the LLM representation space to distinguish it from the potential "consciousness" phenomenon. The experimental results considering the variation of the LLM transformer layer and linguistic range show that the modern transformer-based LLM representation sequence does not show statistically significant indicators of the observed "consciousness" phenomenon, but it shows an interesting pattern under the space-substitution analysis.
