Glossary
This glossary defines the core terms of Therapeutic Education.
Its purpose is to stabilize meaning and enable precise reasoning about learning dynamics.
These terms describe structural properties of learning interactions, not traits of the learner.
Enterability
━━━━━━━━━━━━━━━━━━━━
The possibility of initiating engagement with a learning task.
A task may be understood yet impossible to begin.
When entry is not possible, learning does not occur.
Enterability is therefore the first condition of learning.
A task that cannot be entered cannot teach.
Entry Cost
━━━━━━━━━━━━━━━━━━━━
The total demand a task places on the learner at the moment of beginning.
It is the cost of entering interaction before learning can proceed.
Entry cost is shaped by task structure, context, and momentary conditions.
When entry cost exceeds available capacity, initiation fails.
Capacity
━━━━━━━━━━━━━━━━━━━━
The nervous system’s available resources for initiating and sustaining engagement at a given moment.
Capacity is state-dependent, not stable.
It fluctuates with stress, fatigue, emotion, cognitive load, and environment.
Therapeutic Education treats capacity as a constraint to work with, not a deficit to correct.
Continuity
━━━━━━━━━━━━━━━━━━━━
The persistence of engagement across successive moments of interaction.
Learning unfolds over time.
At each transition, entry must be re-established.
When successive moments remain enterable, engagement stabilizes.
When they do not, engagement fragments.
Continuity is therefore the second condition of sustained learning.
Continuous Enterability
━━━━━━━━━━━━━━━━━━━━
The condition in which successive moments of interaction remain enterable.
Under continuous enterability, effort accumulates.
Without it, effort resets.
Learning persists only while continuous enterability is maintained.
Re-initiation Fatigue
━━━━━━━━━━━━━━━━━━━━
The cumulative depletion caused by repeatedly rebuilding entry into a task.
Each collapse of engagement requires a new initiation.
Each initiation consumes capacity.
Under repeated failure, these costs accumulate faster than recovery.
Re-initiation fatigue is not caused by learning itself, but by repeated attempts to re-enter learning.
It explains why fragmented learning becomes progressively harder even when the task remains within ability.
The Effort Paradox
━━━━━━━━━━━━━━━━━━━━
When a task is non-enterable, increased effort reduces the likelihood of successful engagement.
Each failed attempt consumes capacity.
Reduced capacity raises the effective entry cost of the next attempt.
Under these conditions, effort is not neutral.
It accelerates collapse.
The correct response is structural intervention before the next attempt.
The Restorative Loop
━━━━━━━━━━━━━━━━━━━━
The cycle that emerges when learning becomes continuously enterable.
When entry cost is reduced below capacity, engagement becomes possible.
When engagement is sustained, success becomes repeatable.
Repeated success reverses the cycle of stress, failure, and withdrawal.
Therapeutic Education does not restore the learner directly.
It restores the conditions under which learning can occur.
When these conditions hold, three experiences return:
- competence
- belonging
- the expectation of success
Restoration is not an intervention.
It is the outcome of structural compatibility.
Structural Incompatibility
━━━━━━━━━━━━━━━━━━━━
A condition in which task structure imposes an entry cost exceeding the learner’s available capacity.
Structural incompatibility is not a property of the learner or the task alone.
It is a property of their interaction at a given moment.
When present, learning becomes non-enterable despite intact ability and understanding.
Proxy Learning Response
━━━━━━━━━━━━━━━━━━━━
A behavioral pattern in which task completion occurs without entry into the learning process.
Proxy responses emerge when entry cost exceeds capacity but completion is still required.
They satisfy external demands while leaving learning unchanged.
They are structurally induced, not motivational failures.
Learning Identity
━━━━━━━━━━━━━━━━━━━━
The learner’s internal expectation of whether learning is possible for them.
Repeated exposure to non-enterable tasks reshapes this expectation.
Over time, inability to enter tasks is misinterpreted as inability to learn.
Learning identity is therefore an outcome of structural conditions, not a fixed trait.
Harm Prevention
━━━━━━━━━━━━━━━━━━━━
A design constraint stating that learning systems must not produce predictable psychological harm through repeated non-enterable demands.
Harm prevention does not eliminate challenge.
It eliminates structural conditions that reliably produce collapse of engagement.
Therapeutic Education
━━━━━━━━━━━━━━━━━━━━
A paradigm studying the conditions under which learning remains possible under fluctuating capacity.
It examines the relationship between task structure and nervous system constraints.
Therapeutic Education does not redefine what must be learned.
It defines the conditions under which learning can occur.
It is governed by a single boundary:
Education must not demand what a nervous system cannot give.
