Within the depth-psychology corpus, 'contraction' operates across three distinct but interconnected registers. In the Stoic lineage — most fully developed by Sorabji, Graver, and Inwood — contraction (συστολή) names one of the four generic passions: the psychic shrinking that constitutes distress, defined as a judgement that present evil warrants a drawing-inward of the soul. This is not mere metaphor but a quasi-physical event in the chest, and its fate over time — whether the impulse, the opinion, or the contraction itself abates — is a problem Chrysippus wrestles with at length. In somatic and trauma-informed approaches, Levine treats contraction as one pole of the organism's innate pendulation rhythm, paired irreducibly with expansion; trauma is precisely the failure of this oscillation. Heller's NARM framework extends this to a therapeutic dialectic in which expansion into health predictably triggers contraction, and the clinician's task is to normalize and titrate that rhythm rather than pathologize either pole. Masters brings an explicitly critical-contemplative dimension: the binary that casts expansion as positive and contraction as negative is itself a form of spiritual bypassing. Across these registers, contraction marks the boundary between healthy rhythmic responsiveness and pathological fixity — and the corpus insists that this boundary is far more permeable than common assumption supposes.

expansion is positive, contraction negative; that expansion lifts us and contraction sinks us; that expansion epitomizes yes, contraction no; that expansion is 'higher,' contraction 'lower;' that expansion frees us while contraction entraps us
Masters argues that the idealization of expansion over contraction is a paradigmatic instance of spiritual bypassing, treating a context-dependent rhythmic polarity as an absolute moral hierarchy.

trauma is about being frozen or stuck, pendulation is about the innate organismic rhythm of contraction and expansion. It is, in other words, about getting unstuck by knowing (sensing from the inside), perhaps for the first time, that no matter how horrible one is feeling, those feelings can and will change.
Levine defines pendulation as the organism's healthy rhythmic alternation between contraction and expansion, and locates traumatic pathology precisely in the arrest of this natural oscillation.

it is important to let clients know that this expansion-contraction dynamic is a normal part of the therapeutic process and help them release any fears and judgements they have about it.
Heller frames the expansion-contraction cycle as an expected and normative feature of therapeutic progress in NARM, requiring psychoeducation rather than pathological interpretation.

It seems to me that a belief remains in the form that what is actually present is bad, but that as the belief grows older, (1a) the contraction abates (aniesthai), and, as I think, (1b) the impulse towards con
Sorabji presents Chrysippus's account of grief's fading: the contraction as somatic-psychic concomitant of distress may abate with time even while the belief that something bad has occurred persists.

he evidently defined them as being contractions and expansions on the occasion of (fresh) judgements of evil and good... the four generic emotions as being a contraction, expansion, reaching, or leaning away, but offers the judgements as the cause
Sorabji reconstructs Zeno's and Chrysippus's definitions of the four generic passions, with contraction identified as the bodily-psychic movement that constitutes distress, causally downstream of evaluative judgement.

A NARM therapist keeps in mind how much contact clients can tolerate before becoming disorganized and how much expansion is possible before contraction is triggered.
Heller specifies the clinician's calibratory function: tracking the threshold at which expansion into relational contact tips into defensive contraction for clients with Connection Survival Style.

it is vital to control of the emotions to understand that the contractions and expansions which constitute the mental first movements are no more than sensed inner movements in the chest.
Sorabji argues that locating contractions and expansions as felt movements in the chest is therapeutically essential for Stoic emotional management, enabling a time-gap between first movement and full passion.

the fact that both the impulse to the contraction and the opinion can be taken to be the persistent factor is puzzling, until we consider the relation of the assent to the impulse in the psychology of action.
Inwood examines the technical puzzle within Chrysippean psychology of whether it is the impulse toward contraction or the evaluative opinion that persists as grief fades, arguing the general psychology of action renders this distinction less decisive.

we think that it is not only bad but also such as to justify feeling a contraction in our soul over it. With the passage of time our presentation of the situation changes, when we get a chance to consider it more carefully, and we then think that it is bad, but no longer such as to justify feeling grief.
Inwood reconstructs Chrysippus's account of contraction's decline as a revision of the evaluative judgement that the situation warrants psychic shrinkage, distinguished from the separate judgement that something bad occurred.

Sorabji maps the Stoic taxonomy of generic passions in which contraction (distress) is structurally paired with expansion (pleasure), both constituted by evaluative judgements about present goods and evils.

Try to keep your arm in the position of a hysteric contracture and describe the movement of the arm; you will remark that you have not the same perseverance or courage as the patient
Janet documents hysterical contracture as a dissociated somatic fixation — a bodily contraction that persists beyond voluntary control — anticipating later somatic-trauma frameworks.
