Abstract

This study tests whether early loss of access to ease is better explained by cumulative monitoring (Z_acc) or by a discrete structural transition toward anticipatory testing (Z_shift). Adults aged 25–35 were recruited under double-blind conditions based on childhood context and exposed to a three-day non-evaluative constraint-based procedure. No outcome measures were imposed; spontaneous self-report served as the primary signal. Participants were independently randomized to contextual constraint only or contextual constraint plus a brief UT99 session.

Design Overview

Between-groups comparison: only-child low-control childhood vs control group.
Double-blind: neither participants nor interacting experimenters knew group assignment.
No evaluative prompts, ratings, or monitoring during the procedure.
Primary outcome: spontaneous reporting of abrupt experiential shift.
Optional UT99 manipulation to test catalytic versus non-essential role.

Core Theoretical Test

If cumulative monitoring alone explains loss, early permissive childhood should strongly predict re-entry.
If a discrete structural shift can close access, permissive childhood will not be uniformly protective.
If UT99 functions as catalyst, spontaneous reporting should increase in context+UT99 cells.

Primary Observation Pattern

When present, reports were abrupt, immediately recognizable, and self-announcing. Absence of reporting was unambiguous. Spontaneous reports were more frequent among only-child low-control participants but not uniformly preserved, supporting a dual mechanism model.

Methodological Contribution

The study demonstrates a regime-sensitive design minimizing evaluative contamination. It treats spontaneous recognition rather than elicited measurement as primary evidence, highlighting limitations of conventional evaluative methods for studying regimes that collapse under observation.
