Explanatory Power¶

Self from Coupled Predictive Loops Hypothesis

1. Note¶

This document demonstrates the theory’s capacity to explain existing phenomena. These explanations do not constitute proof, but aim to show that the framework has:

Structural consistency
Cross-phenomenon unification
Compatibility with existing research

2. Unity of Consciousness¶

Phenomenon¶

Subjective experience appears as a single, unified whole rather than multiple independent streams.

Explanation in This Model¶

Multiple internal signals (prediction, matching, state integration) exist within the system. These signals:

Are highly synchronized in time
Refer to the same state variables
Share a representational space
Lack independent channels or external references

→ Satisfy the conditions for indistinguishability

Therefore:

Multiple signals collapse into a single state along the dominant trajectory, manifesting as unified experience.

Key Mechanisms¶

Signal coupling
Indistinguishability principle
Dominant trajectory constraint

3. Sense of Thinking¶

Phenomenon¶

Thinking is experienced as a continuous and unified process.

Explanation in This Model¶

Thinking corresponds to state evolution along the dominant trajectory, involving:

Expansion of multiple predictions
Integration of current state
Prediction–evolution matching

Because these processes:

Occur synchronously
Refer to the same trajectory state
Cannot be distinguished in origin

Therefore:

They are unified and attributed as a single process, experienced as “I am thinking.”

4. Sense of Agency¶

Phenomenon¶

Individuals experience themselves as actively choosing and controlling actions.

Explanation in This Model¶

The system generates multiple predictive trajectories, and actual evolution aligns with one of them.

When the following conditions hold:

Prediction matches actual evolution
The match persists over time
The trajectory aligns with the dominant trajectory

Then:

The current behavior is attributed to the dominant trajectory → experienced as “generated by me.”

If these conditions are not met:

→ Attribution may shift → producing a sense of external origin

Key Point¶

Agency is fundamentally:

The result of attribution based on prediction–evolution matching

5. Continuity of Self¶

Phenomenon¶

Individuals experience themselves as the same person over time.

Explanation in This Model¶

Historical states are compressed into trajectory structures
Current states align with predicted trajectories
Continuity error is minimized

Therefore:

The current state is interpreted as a continuation of the same trajectory.

Core Expression¶

Self = trajectory with minimal continuity error

6. Uniqueness of Self¶

Phenomenon¶

Individuals typically experience only a single self.

Explanation in This Model¶

Although multiple predictive trajectories exist:

Continuity error cannot be minimized simultaneously across multiple trajectories
Multiple trajectories introduce prediction conflicts
The system converges toward a stable solution (a single dominant trajectory)

Therefore:

Only one trajectory is continuously selected → forming a unique self.

7. Behavioral Attribution (Self vs External)¶

Phenomenon¶

Individuals can distinguish between:

Self-generated actions
Externally caused events

Explanation in This Model¶

Attribution is based on:

If actual evolution matches a predictive trajectory → attributed to that trajectory
If matching fails or becomes discontinuous → attribution shifts

Therefore:

Whether a behavior is experienced as self-generated depends on matching and continuity.

8. Disturbances of Self¶

Phenomenon¶

In certain conditions, individuals experience:

Loss of voluntary control
Externalization of thoughts
Instability of self

Explanation in This Model¶

Possible mechanisms include:

Failure of prediction–evolution matching
Increased continuity error
Instability of the dominant trajectory
Weakening of signal coupling

These lead to:

Breakdown or shift in attribution mechanisms
Instability of self-structure

9. Emergence of the First-Person Perspective¶

Phenomenon¶

Experience is expressed in the form of “I.”

Explanation in This Model¶

Generation pathway:

Multi-prediction and multi-signal coupling
→ Indistinguishability
→ Formation of dominant trajectory
→ Single internal representation
→ Output interface
→ “I”

Therefore:

The first-person perspective is a structural output, not an independent entity.

10. Why Experience Is Indivisible¶

Phenomenon¶

Individuals cannot decompose experience into multiple sources.

Explanation in This Model¶

Because:

Signals share a representational space
There are no independent channels
There is no external reference
Signals are highly synchronized in time

The system cannot perform source separation:

Multiple signals collapse into a single representational state.

Thus, experience appears as an indivisible whole.

11. Uncertainty and Multi-Prediction¶

Phenomenon¶

Behavior exhibits partial indeterminacy and flexibility.

Explanation in This Model¶

The system inherently has a multi-prediction structure:

Generates multiple possible trajectories simultaneously
Models different potential scenarios
Retains uncertainty during selection

Therefore:

Uncertainty arises from the multi-prediction structure, not necessarily from external perturbations.

12. Unified Explanatory Power¶

This model explains, through a unified mechanism:

Unity of experience
Continuity of self
Agency (as attribution mechanism)
Uniqueness of self
Behavioral attribution
Disturbances of self

All of these phenomena arise from:

Multi-prediction structure + trajectory selection + indistinguishability + continuity constraints

13. Limitations¶

The current explanatory scope still has limitations:

Does not address why subjective experience exists (the hard problem)
Continuity error is not fully formalized
Lacks quantitative predictions
Lacks experimental validation

14. Summary¶

The explanatory strength of this model lies in:

Using a single structural mechanism to explain multiple classes of phenomena
Avoiding the introduction of additional entities
Maintaining compatibility with existing cognitive science frameworks

Its core can be summarized as:

The self is a trajectory continuously selected within a multi-prediction system; subjective experience is the indistinguishable integration of multiple signals along that trajectory; and agency is an attribution mechanism based on sustained prediction–evolution matching.
